Description

The present invention relates to a technique for removing volatile pollutants (VOC) such as toluene and other organic solvents and various foreign substances (pollutants, bad odor, smoke, etc.) floating in the air. More specifically, the present invention relates to a technique for removing VOC from a gas containing VOC.

  For example, a large amount of organic solvent is used in a printing factory or the like. If the volatilized organic solvent is contained in the exhaust from the facility where the organic solvent is used and diffuses, the surrounding environment of the facility where the organic solvent is used may be adversely affected.

  In order to remove various foreign matters (contaminants, bad odor, smoke, etc.) floating in the air, for example, VOC, it is conceivable to perform combustion treatment with a gas turbine. However, the VOC contained in the exhaust from the facility where the organic solvent is used is very small and is too small to be used as fuel for the gas turbine.

In order to remove VOC contained in the exhaust from the organic solvent use facility, there is a technique in which an activated carbon tank is interposed in the exhaust system to adsorb the VOC in the exhaust to the activated carbon (for example, Non-Patent Document 1). ).
However, in such a technique, in order to regenerate the activated carbon tank, it is necessary to repeat the adsorption process and the regeneration process, and it is necessary to provide two lines interposing the activated carbon tank.
For this reason, for example, in a facility that uses a small amount of organic solvent and produces a relatively small amount of VOC, such as a small-scale printing factory, a VOC treatment system that uses at least two activated carbon tanks is compared to the scale of the entire facility. Will be too large and not cost effective

As another conventional technique, there is a technique for detoxifying VOC by a chemical reaction by combining an electric hot air generator and a platinum honeycomb catalyst (for example, see Non-Patent Document 2).
However, in such a technique, since electricity must be constantly supplied and heated to the reaction start temperature while removing the VOC, a large amount of electricity is consumed, resulting in an increase in VOC processing cost. The problem cannot be solved.

  The present invention has been proposed in view of the above-described problems of the prior art, can reduce the processing cost of VOC, and can reliably collect VOC even when the VOC concentration is very low. The purpose is to provide various reactors.

  The reaction apparatus of the present invention has a catalyst (1) for cleaning unreacted gas (process gas) to be treated, and the catalyst (1) has a plurality of paths (1a) extending in the longitudinal direction. The catalyst (1) is accommodated in a casing (3), and is configured to be rotatable around a rotation axis (R) extending in the longitudinal direction. ) Is connected to an air supply system line (4) through which unreacted gas flows and a discharge line (5) from which gas after reacting with the catalyst is discharged, and the catalyst (1) in the casing (3) is connected. ) The upper space is partitioned by a separator (7) into an air supply side (32I) to which an air supply system line (4) is connected and an exhaust side (32E) to which an exhaust line (5) is connected (catalyst) Of the separator so as to extend radially with respect to the catalyst and to be rotatable with respect to the catalyst. 7 is attached), the separator (7) is formed by laminating a plurality of flexible plate-like members (for example, metal foils 71 and 72 formed relatively thin), and each plate-like member The members (71, 72) are arranged in contact with the catalyst (1), and a plurality of slits (71s, 72s) are formed on the side in contact with the catalyst (1). ) In the longitudinal direction (radial direction of the rotatable catalyst) except for the central slit (71sc), the positions of the slits (71s, 72s) of the adjacent plate members are shifted from each other, and the separator of the catalyst (1) The plurality of paths (1a) formed in the catalyst (1) communicate with the member (2b) provided on the side (opposite side) separated from (7, 7B).

Here, “the space above the catalyst (1) in the casing (3)”, that is, the “supply side (32I) to which the supply system line (4) is connected by the separator (7) and the discharge line (5) are connected. The space partitioned by the discharge side (32E) thus made means the space inside the lid (upper lid 32) of the casing (3). An air supply system line (4) and a discharge line (5) are connected to the lid (upper lid 32).
Further, the above-described member (the member 2b provided on the side separated from the separator of the catalyst) is intended to include a configuration such as an end cap.

In carrying out the present invention, the end of the member (22b) (provided on the side separated from the separators 7 and 7B of the catalyst 1) opposite to the separators (7 and 7B) is configured as a double bottom. The pressure between the double bottoms (22v) is preferably negative (see FIG. 10).
Or in this invention, it is preferable to comprise the member (catalyst rotor 2,202) which fits the said catalyst in the double structure which consists of an outer member (23O) and an inner side (inner member 23I) ( FIG. 11). The outer member (23O) and the inner member (23I) can be integrally configured by a closed end portion (upper edge portion 23U).

In the present invention, the catalyst (catalyst rotor 2) rotates, and the separator (7) that partitions the supply side (32I) and the exhaust side (32E) while contacting the rotating catalyst rotor (2) is separated. I have.
The untreated gas is supplied to the supply side (32I), enters the catalyst (1), and is discharged from the exhaust side (32O). The untreated gas is cleaned by an exothermic reaction while passing through the catalyst (1).

Here, even if the purified gas after reaction on the exhaust side (32E) is discharged out of the casing (3), the combustion heat (reaction heat) remains. When the catalyst rotor (2) rotates to reach the supply side (32I) and the untreated gas flows, the combustion heat (reaction heat) remaining in each path (1a) is input to the untreated gas. . Then, the temperature of the process gas that has flowed into the catalyst (1) is raised to a temperature sufficient to cause a reaction.
That is, according to the configuration of the present invention, the catalyst rotor (2) can be rotated, and the upper side of the catalyst (1) is divided into the supply side (32I) and the exhaust side (32E) by the separators (7, 7B). Thus, the same effect as that of the heat exchanger is achieved.
As a result, an expensive heat exchanger can be omitted.

Further, in the present invention, if a separator (7) configured by laminating a plurality of relatively thin plate-like members (71, 72) is configured to partition the air supply side (32I) and the exhaust side (32E) ( (2) The untreated gas is prevented from leaking to the exhaust side.
That is, the separator (7) formed by laminating a plurality of relatively thin plate-like members (71, 72) is always in contact with the rotating catalyst (1). Since the contact is always made, the air supply side (32I) and the exhaust side (32E) can be sufficiently sealed.

  Here, since the separator (7) in contact with the rotating catalyst (1) is formed by bonding a plurality of relatively thin plate-like members (71, 72), it causes elastic deformation. Thus, the separator (7) can be prevented from wearing the catalyst (1) while being bent (bending). Moreover, it does not become a resistance of rotation of the catalyst (1).

Slits (71s, 72s) are formed on the catalyst side of the individual plate members (71, 72), ensuring flexibility (bending due to elastic deformation) between the slits (71s, 72s), Breakage of the rotating catalyst (1) can be prevented.
Here, since the positions of the slits (71 s, 72 s) of the adjacent plate members (71, 72) are shifted, the slits (71 s, 72 s) in the whole of the plurality of plate members (71, 72) are A labyrinth seal will be constructed. The labyrinth seal prevents unreacted gas from leaking to the exhaust side (32E).

  Even if the separator (7B) in the present invention is configured by a curtain (for example, an air curtain (nozzle 7Bt) thereof) configured by jetting gas (Claim 3), the supply side (32I) and the exhaust side (32E) Can be sufficiently sealed, and there is no fear that the rotation resistance of the catalyst (1) or the catalyst (1) will be worn.

  In the present invention, the plurality of paths (1a) formed in the catalyst (1) are formed on a member (2b) provided on the side (opposite side) separated from the separator (7, 7B) of the catalyst (1). When communicating (Claim 4), after the gas that has entered the path (1a) communicating with the supply side (32I) in the catalyst (1) and caused an exothermic reaction flows into the member (2b), Since the gas flows to the path (1a) communicating with the exhaust side (32E), the gas surely flows from the supply side (32I) to the exhaust side (32E).

Here, the end opposite to the separator (7, 7B) of the member (22b) provided on the side separated from the separator (7, 7B) of the catalyst (1) is configured as a double bottom, If the pressure between the double bottoms (22v) is made negative (see FIG. 10), the space (22v) between the double bottoms will insulate (vacuum insulation), so the reaction on the catalyst (1) side It is prevented that heat is radiated from the hollow member (22b) to the surroundings.
Moreover, since heat insulation (vacuum insulation) is performed in the space (22v) between the double bottoms, the reaction heat on the catalyst (1) side passes through the double bottom part (22b) to the electric motor (12) side. Is prevented from being transmitted to. Accordingly, it is possible to prevent the rotation transmission member (such as the drive shaft 10) and the rotation power source (the electric motor 12) that are in contact with the double bottom portion (22b) from being heated.
Even if the member (catalyst rotors 2, 202) into which the catalyst is fitted has a double structure consisting of the outer member (23O) and the inner side (inner member 23I) (see FIG. 11), the effect of shaking An effect is obtained.

In the present invention, basically, the preheating heater (80) is turned off except during startup.
At the time of start-up, it is necessary to raise the temperature to such an extent that a reaction is caused by the preheating heater (80), but thereafter, the exothermic reaction heat in the catalyst (1) remains in each of the plurality of paths (1a) of the catalyst (1). Therefore, even if it is not heated by the preheating heater (80), the temperature of the untreated gas can be raised to the extent that the reaction occurs due to the reaction heat remaining in the path (1a).
Unlike the prior art, it is not necessary to keep the preheater heater (80) always on.
Therefore, the present invention consumes very little energy except during startup.

  Embodiments of the present invention will be described below with reference to the accompanying drawings.

  First, the operating principle of the reaction apparatus of the present invention will be described with reference to FIGS. FIG. 23 is a block diagram schematically showing a process in which the unreacted gas to be treated is cleaned by the catalyst 1.

  In FIG. 24, as an example, the unreacted gas to be processed has a calorific value of 1000 kcal / kg in the state of air-fuel mixture. Such unreacted gas has a low mixing rate in the atmosphere and does not react, and even if it is condensed, it is too thin to be recovered.

Therefore, the unreacted gas is fed into the preheating device K2 by, for example, the blower K1.
Since the reaction of the gas to be treated is not progressing at the initial stage of the process, reaction heat is hardly generated and a preheating device K2 is provided, and the gas can be reacted by the preheating device (for example, an electric heater) K2. Preheat to approximately 350 ° C.
The gas preheated to 350 ° C. passes through the heat exchange device K3. However, heat exchange cannot be performed in the heat exchange device K3 because the reaction heat is not sufficiently generated since the process is still in the initial stage. Then, it is fed into the reactor (catalyst) 1 as it is.

  The gas sent to the catalyst is heated to 200 ° C. and reaches 550 ° C. by a reaction in the reactor 1 (contacting platinum in the catalyst to cause an oxidation reaction (exothermic reaction)).

  In other words, due to the reaction in the reaction apparatus 1, the exhaust temperature is increased by 200 ° C. for the increased temperature.

  The treated gas discharged from the reactor 1 is increased by 550 ° C. from the atmospheric temperature Ta, and the heat exchange device K3 inputs a heat amount corresponding to 350 ° C. from the energy held by the treated gas. .

Here, as can be judged from FIG. 24, the necessary heat exchange rate μ of the heat exchanger K3 is
μ = ((Ta + 350) −Ta) / ((Ta + 550) −Ta) = 350/550 = 0.64
64% is sufficient.
If the efficiency of the heat exchanger is improved, the inlet temperature of the reactor 1 may be 400 ° C. If the reactor inlet temperature is low (some solvents may cause this), improving the efficiency of the heat exchanger will raise the reactor inlet temperature (eg up to 400 ° C.). Therefore, it can respond to such a case.

The preheating device K2 is a start-up heater, and at the start of operation, the temperature does not rise in the heat exchanger K3. Therefore, the preheating device K2 can be heated by the preheating device K2 and can be reacted by the catalyst (reaction device 1). Is the purpose.
Therefore, after the reaction reaches a certain level, the preheating device K2 is not operated.

However, in the principle diagram shown in FIG. 24, the heat exchanger K3 is used, and such a heat exchanger is expensive and bulky as a whole apparatus.
Therefore, in the embodiment of the present invention, an apparatus in which a heat exchanger and a reaction apparatus are combined as shown in FIG. 25 is proposed.

In FIG. 25, the catalyst (catalyst rotor) 1 whose upper end is partitioned by the separator 7 is rotated. With such a configuration, the catalyst 1 can act as a heat exchanger.
That is, even if the purified gas after reaction is exhausted on the exhaust side E, combustion heat (reaction heat) remains. Then, when the catalyst 1 rotates (arrow R) and reaches the input side I and unprocessed gas (not shown) flows in, it remains in each path (a large number of tubes 1a formed in the direction of the rotation axis of the catalyst). Combustion heat (reaction heat) is input to the untreated gas, and has the same effect as the heat exchanger K3 described with reference to FIG.
That is, the temperature can be raised to a temperature sufficient for the untreated gas flowing into the catalyst 1 to react.

  Next, a first embodiment will be described with reference to FIGS.

  In FIG. 1, a catalyst 1 having a cylindrical shape and having a plurality of paths 1 a parallel to the axial center line (rotation center) R of the cylinder and carrying platinum Pt is fitted into a cylindrical catalyst rotor 2. .

The catalyst rotor 2 is configured by a cylindrical body 2a and a hollow member 2b having a partially spherical bottom at the lower end of the cylindrical body 2a, which are integrally connected by, for example, welding. Maximum diameter portions 2c and 2c are formed slightly above the connection position between the upper end of the cylindrical body 2a and the hollow member 2b, and are fitted to the inner periphery of a radial bearing Br described later.
A step portion 2d is formed in the vicinity of the lower end of the cylindrical body 2a of the catalyst rotor 2, and is locked so that the lower end of the catalyst 1 is in contact with the step portion 2d.

  The catalyst rotor 2 is accommodated in a casing 3. The casing 3 includes an outer cylinder 31 that houses the catalyst rotor 2, an upper lid 32 that is airtightly joined to the upper end of the outer cylinder 31 via a seal member 34, and a lower end of the outer cylinder 31 via a seal member 34. It is comprised by the lower cover 33 joined airtightly.

  At the upper and lower end portions of the outer cylinder 31, radial bearings Br for freely accommodating the catalyst are fitted.

On the upper surface of the upper lid 32, an air supply port 32i for connecting the air supply system line 4 and an exhaust port 32o for connecting the exhaust system line 5 are formed. A spare communication hole 32 e is formed around the side of the upper lid 32.
Here, an air supply system line (4) and a discharge line (5) are connected to the upper lid 32 (lid body) of the casing 3. The space inside the upper lid 32 constitutes a “space above the catalyst (1) in the casing (3)”, and the space is divided into a supply side 32I and a discharge side 32E by a separator 7 described later. It is partitioned. The air supply system line 4 is connected to the air supply side 32I (partitioned by the separator 7) of the upper lid 32 (cover body), and the discharge line 5 is connected to the discharge side 32E.

The supply line 4 for supplying process gas (untreated gas) to the catalyst is provided with a starter spare heater 80.
The catalyst initially treated with the process gas (untreated gas VOC) is at room temperature and does not reach the temperature required for the reaction. Therefore, it is necessary to heat with a starter heater until reaction heat is generated.
Here, when a heater is disposed in the hollow member 2b at the bottom of the catalyst rotor 2, the catalyst rotor 2 rotates, so that power supply to the heater becomes difficult, and a slip ring or the like must be used. If a spare heater 80 for a starter is provided in the supply system line 4 as described above instead of using a slip ring or the like, power supply to the heater is facilitated.

  In addition, a partition wall 6 is fixed to the inner wall surface of the upper lid 32 by welding, for example, so as to divide the inside into two parts, that is, the intake port 32i side and the exhaust port 32o side through the center of the upper surface.

  As shown in detail in FIG. 2, the partition wall 6 is provided with bolt holes 6 a for attaching the separator 7 in the vicinity of the lower end at five locations in the illustrated example. Further, a groove 6b having a uniform depth is formed in the center in the thickness direction at the lower end of the partition wall 6 so that one of the plate-like members described below constituting the separator 7 can be inserted. ing.

Each of the separators 7 is relatively thin, including a single first plate member 71 shown in detail in FIG. 3 and two second plate members 72 shown in detail in FIG. It is comprised with the plate-shaped member (for example, very thin stainless steel plate) which is easy to do.
The material only needs to have both heat resistance of 500 ° C. to 600 ° C., which is the reaction temperature in the catalyst, flexibility, and availability, and in the embodiment, it is particularly easily available. Stainless steel sheet is selected.

  Referring to FIG. 3, the first plate-like member 71 includes a plurality of slits 71s having the same pitch p including the central slit 71sc, and is formed over substantially the entire length. The mounting holes 71a having the same pitch as the bolt holes 6a formed in the partition wall 6 are drilled at five locations.

  Referring to FIG. 4, the second plate member 72 has a plurality of slits 72s having substantially the same pitch p except for the central slit 71sc, and is formed above the slit 72s. Mounting holes 72a having the same pitch as the bolt holes 6a formed in the partition wall 6 are drilled at five locations.

  In the first plate-like member 71 and the second plate-like member 72, the pitch of the mounting holes 71a, 72a and the pitch of the slits 71s, 72s are both equal, and the mounting holes 71a of the first plate-shaped member 71 are the same. And the mounting holes 72a of the second plate member 72 are mounted in the mounting holes 6a of the partition wall 6, the slits 71s, 72s of the first and second plate members 71, 72 are ½ pitch from each other. It is formed so as to be shifted one by one.

FIG. 5 shows a retainer 73 for reliably pressing the plate member 72 that is thin and easily deformed against the partition wall 6 when the second plate member 72 is attached to the partition wall 6.
At the center in the width direction of the retainer 73, a mounting hole 73a having the same pitch as the bolt hole of the partition wall 6 is formed.

When the separator 7 is formed, that is, when the first plate member 71 and the second plate member 72 are attached to the partition wall 6 using the retainer 73, the slits 71s and 72s of the plate members 71 and 72 are formed. A certain plate end is attached in a state of being substantially in contact with the upper surface of the catalyst 1.
The two second plate members 72 and the first plate member 71 have a labyrinth structure because the slits are shifted from each other by a half pitch.
Such a labyrinth structure is configured to prevent the untreated gas from leaking from the supply side (the region indicated by reference numeral 32I in FIG. 1) to the discharge side (the region indicated by reference numeral 32E in FIG. 1). ing.

Since the end portions of the plate-like members 71 and 72 having the slits 71 s and 72 s are attached in a state of being substantially in contact with the upper surface of the catalyst 1, the separator 7 (plate-like members 71 and 72) is caused by contact resistance if contacted temporarily. 6 is deformed so as to be dragged in the direction opposite to the rotation direction of the arrow Y, as shown in FIG. That is, the rotation direction of the catalyst rotor 2 reverses the direction in which the separator 7 (plate-like members 71 and 72) bends at the middle.
Therefore, the slits 71sc and 72sc are inserted in the middle of any of the three plates, and the board is allowed to bend in the reverse direction with the middle (rotation axis R) as a boundary.
Furthermore, the thermal expansion of the catalyst rotor 2 in the longitudinal direction of the rotor can be absorbed by the flexibility of the separator 7 (plate-like members 71 and 72).

Referring to FIG. 1 again, a columnar protrusion 33c is formed at the center of the bottom 33a of the lower lid 33 of the casing 3, and a columnar hollow 33d is formed inside the protrusion 33c. Is formed.
An insertion hole 33e through which the drive shaft 10 for rotationally driving the catalyst rotor 2 is inserted is formed on the upper and lower surfaces sandwiching the hollow portion 33d.

  The drive shaft 10 is formed by a large-diameter portion 10 a, a medium-diameter portion 10 b, and a small-diameter portion 10 c, and an end portion of the small-diameter portion 10 c is connected to the rotating shaft 12 a of the electric motor 12 via a connecting member 11.

  The middle diameter portion 10 b is rotatably supported by a two-layer thrust bearing 14 accommodated in the bearing housing 13. Further, a male screw is formed at the small-diameter portion side boundary portion of the medium-diameter portion 10b, and is configured to be screwed with the female screw of the positioning nut N2.

  A plate-like member 8 is mounted concentrically with the large-diameter portion 10a at the end of the large-diameter portion 10a, and a bearing portion 10d that is thin in an arc shape is formed in the middle of the large-diameter portion 10a. . The bearing portion 10d is formed at the same height position as the hollow portion 33d of the lower lid 33, and is configured to take a large space in the hollow portion 33d.

  By providing a cylindrical hollow portion 33d formed inside the protruding portion 33c of the bottom portion 33a of the lower lid 33 of the casing 3 and a bearing portion 10d formed on the large diameter portion 10a of the drive shaft 10, a catalyst is obtained. The reaction heat generated in the rotor 2 is hardly transmitted to the thrust bearing 14 side. That is, the reaction heat of the catalyst 1 is not easily transmitted to the thrust bearing 14, and the lubricating grease in the thrust bearing 14 is protected from high temperatures.

The plate-like member 8 supports the catalyst rotor 2 so as to make point contact at the lower end vertex of the hollow member 2 b of the partial spherical body of the catalyst rotor 2. In the vicinity of the outer edge of the plate-like member 8, a plurality of drive pins 9 (two in the figure) parallel to the drive shaft 10 are erected, and the end of the drive pin 9 is the hollow member 2 b of the rotor 2. For example, it is fixed by welding or the like in the vicinity of the outer edge of the lower end.
Therefore, the driving force of the electric motor 12 is transmitted to the catalyst rotor 2 through the driving shaft 10 by the plurality of driving pins 9 erected on the plate member 8.

Although not clearly shown in the drawing, one end of the bearing housing 13 on the side of the catalyst rotor 2 is formed with a retaining edge for the thrust bearing 14 and not clearly shown in the drawing on the open side of the bearing housing hole at the other end. Has an internal thread.
The male screw of the ring nut 16 is screwed into the female screw, and the end of the ring nut 16 and the retaining edge prevent the multi-layer thrust bearing 14 from falling out of the bearing housing 13. .

  First, the thrust bearing 14 is engaged with the drive shaft 10 at the boundary (step) between the large-diameter portion 10a and the medium-diameter portion 10b of the drive shaft 10 and the end portion on the small-diameter portion 10c side of the medium-diameter portion 10b. This is performed by a locking nut N2 that is screwed into the male screw portion formed in the above.

  The electric motor 12 is connected to the bottom member 33 a of the lower lid 33 of the casing 3 through the horizontal support member 17 and the vertical support member 18.

  In the first embodiment having the above-described configuration, the catalyst rotor 2 is configured to be rotatable, and is partitioned into the supply side 32I and the exhaust side 32E while being in contact with the upper surface of the rotating catalyst 1. By providing the separator 7, the untreated gas is supplied to the supply side 32I. The processing gas supplied to the air supply side 32I and entering the catalyst 1 is discharged from the exhaust side 32E while generating reaction heat while reacting. That is, the gas is purified by an exothermic reaction while passing through the catalyst 1.

Here, even if the purified gas after the reaction is exhausted on the exhaust side 32E, the combustion heat (reaction heat) remains. When the catalyst rotor 1 rotates to reach the supply side 32I and the untreated gas flows in, the combustion heat (reaction heat) remaining in each path 1a is input to the untreated gas. Since the process gas flowing into the catalyst 1 is heated to a temperature sufficient to cause a reaction, the same effect as that of a heat exchanger is achieved. As a result, an expensive heat exchanger can be omitted.

In the present embodiment, since the separator 7 formed by bonding a plurality of relatively thin plate-like members 71 and 72 separates the supply side 32I and the exhaust side 32E, untreated gas leaks to the exhaust side 32E. It can be prevented that it comes out.
That is, the separator 7 formed by bonding a plurality of relatively thin plate-like members 71 and 72 is always in contact with the rotating catalyst 1. Since the contact is always made, the supply side 32I and the exhaust side 32E can be sufficiently sealed.

  The separator 7 that is in contact with the rotating catalyst 1 is formed by laminating a plurality of relatively thin plate-like members 71 and 72, so that it can be contacted while elastically deforming (bending). is there. Therefore, wear of the catalyst 1 by the separator 7 can be prevented. Further, the presence of the separator 7 does not become a great resistance to the rotation of the catalyst rotor 2.

Since the slits 71 s and 72 s are formed on the catalyst 1 side of the individual plate-like members 71 and 72, the catalyst 1 that rotates while guaranteeing flexibility (bending due to elastic deformation) between the slits 71 s and 72 s. Can be prevented from being damaged.
Since the positions of the slits 71s and 72s of the plate members 71 and 72 adjacent to each other are shifted, the slits 71s and 72s form a labyrinth seal in the whole of the plurality of plate members 71 and 72. Such a labyrinth seal prevents unreacted gas from leaking from the supply side 32I to the exhaust side 32E.

  In the present invention, the catalyst 1 is integrally attached to the hollow member 2b catalyst rotor 2 on the opposite side of the catalyst 1 from contacting the separator 7, and the plurality of paths 1a are communicated with the hollow member 2b. Since the gas that has entered the path 1a communicating with the air supply side 32I in the inside and has caused an exothermic reaction flows into the hollow member 2b and then flows into the path 1a communicated with the exhaust side 32E, the gas is discharged from the air supply side 32I. The gas surely flows to the side 32E.

In the first embodiment, the preheating heater 80 is basically turned off except during startup.
At the time of start-up, it is necessary to raise the temperature to such an extent that a reaction is caused by the preheating heater 80, but thereafter, the exothermic reaction heat in the catalyst 1 remains in each of the plurality of paths 1 a of the catalyst 1. Even without overheating, the heat of reaction remaining in the path 1a can raise the temperature of the untreated gas to such an extent that a reaction occurs.
That is, unlike the prior art, it is not necessary to keep the heater always on.
Therefore, this embodiment has very little energy consumption except at the time of startup.

  Next, a second embodiment will be described with reference to FIG.

In the first embodiment of FIGS. 1 to 6, the separator 7 is an embodiment using a plurality of thin and flexible plate-like members 71 and 72 made of a high stainless steel plate.
On the other hand, 2nd Embodiment of FIG. 7 is embodiment using the curtain (for example, air curtain) comprised by ejecting gas. A configuration different from the first embodiment will be described below.

Around the cylinder of the upper lid 32B of the casing 3B, an air supply port 32Bi and an exhaust port 32Bo are formed on the opposite side of the air supply port 32Bi. At the center of the upper surface of the upper lid 32B, a pipe taper screw hole 32Bt that communicates the inside and outside of the upper lid 32B is formed.
Further, the inner wall of the upper lid 32B includes the pipe taper screw hole 32Bt, and a curtain-like nozzle 7B is formed over the entire inner wall surface so as to divide the upper lid 32B into an air supply side 32I and an exhaust side 32E. ing.
A slight gap is formed between the tapered tip 7Bt of the nozzle nozzle 7B and the catalyst 1. Compressed air is supplied to the nozzle 7B from a compressed air supply source (not shown), and the compressed air is injected toward the upper surface of the catalyst 1 from the nozzle tip 7Bt.
Except for the configuration described above, the second embodiment is substantially the same as the first embodiment shown in FIGS.

According to the second embodiment having such a configuration, since the curtain (air curtain) configured by ejecting gas (for example, compressed air) from the nozzle 7B is used as the separator, the supply side 32I and the exhaust side 32E are used. Can be sufficiently sealed, and there is no fear of causing rotation resistance of the catalyst 1 or wearing out of the catalyst 1.
That is, since a mechanism for blowing compressed air is employed, the pressure can prevent unreacted gas from bypassing the catalyst and leaking from the inlet side to the outlet side.

  Next, an embodiment of the third embodiment will be described with reference to FIG.

In the first embodiment of FIG. 1, when the shaft (rotating shaft) R that rotates the rotor is overheated, for example, the grease for lubrication enclosed in the thrust bearing 14 is melted, and the drive shaft 10 and the bearing (bearing case). 13 may be burned.
In order to prevent such a situation, an embodiment provided with a mechanism for blowing unreacted gas for cooling the “rotating shaft of the rotating catalyst (shaft connected to the output shaft of the motor)” is shown in FIG. It is one embodiment of 3 embodiment.

  One embodiment of the third embodiment of FIG. 8 is different from the embodiment of FIGS. 1 to 6 in the hollow portion 33d formed inside the cylindrical protrusion 33c at the bottom of the lower lid 33 of the casing 3; For example, a tube taper screw Tp that communicates the inside and the outside of the hollow portion 33d is formed, and the tube taper screw Tp and a spare communication hole 32e formed around the side of the casing upper lid 32 are communicated by a tube T with a dedicated cap. (That is, the air inlet side 32I of the upper lid 32 and the hollow portion 33d of the lower lid 33 communicate with each other by the tube T).

  As described above, by connecting the air supply port side 32I and the hollow portion 33d with the dedicated tube T, the unreacted and relatively low temperature processing target gas is formed into a columnar protrusion at the bottom of the lower lid 33 of the casing 3. The drive shaft 10 that is attracted to the hollow portion 33d formed inside 33c and penetrates through the hollow portion 33d is cooled. Since the drive shaft 10 is cooled halfway, the reaction heat of the catalyst 1 is not transmitted to the thrust bearing 14, preventing melting of lubricating grease in the thrust bearing 14, or preventing failure of the electric motor 12 due to an excessively high temperature. Is planned.

  Except for the difference in the above configuration, an embodiment of the third embodiment of FIG. 8 is substantially the same as the first embodiment of FIGS.

  Next, another embodiment of the third embodiment will be described with reference to FIG.

Another embodiment of the third embodiment of FIG. 9 is different from the embodiment of the third embodiment of FIG. 8 in that, for example, an air compressor C or a blower is used separately from the air compressor C to a dedicated tube. This is an embodiment in which T is connected to a pipe taper screw Tp communicating between the inside and the outside of the hollow portion 33d.
Other configurations and operational effects are the same as those of the third embodiment shown in FIG.

Next, a fourth embodiment will be described with reference to FIG.
In the fourth embodiment of FIG. 10, the hollow member 2b at the lower end of the catalyst rotor 2 is double-bottomed with respect to the first embodiment of FIGS. 1 to 6 (the sign of the hollow member in the fourth embodiment is 22b). In this embodiment, the double bottom space 22v is evacuated.
Other configurations are the same as those of the first embodiment shown in FIGS.

The hollow member 22b at the lower end of the catalyst rotor 2 has a double bottom, and the space 22v has a vacuum structure, so that heat insulation can be achieved and the influence of the reaction heat of the catalyst 1 on the thrust bearing 14 can be prevented.
That is, the lubricating grease in the bearing 14 can be prevented from melting, or the motor can be prevented from being damaged due to an excessively high temperature.

  Next, a fifth embodiment of the present invention will be described with reference to FIG. In the fourth embodiment of FIG. 10, only the lower end member 2b of the catalyst rotor 2 has a double bottom, whereas in the fifth embodiment of FIG. 11, the entire catalyst rotor has a double structure.

FIG. 11 shows a catalyst rotor 202 according to the fifth embodiment. As is apparent from FIG. 11, the catalyst rotor 202 includes an outer member 23 </ b> O constituting the outer side of the double structure and an inner member 23 </ b> I constituting the inner side.
The outer member 23O is configured such that the tubular body 2a-1 and the lower end (bottom) member 2b-1 are integrally connected, for example, by welding or the like. On the other hand, the inner member 23I is configured such that the cylindrical body 2a-2 and the lower end (bottom) member 2b-2 are integrally connected by, for example, welding.

The outer member 23O and the inner member 23I are integrally configured by configuring the upper edge portion 23U as a closed end portion.
Here, in order to improve heat insulation, it is preferable that the space 23v between the outer member 23O and the inner member 23I has a negative pressure.

  In the fifth embodiment of FIG. 11, since the catalyst rotor 202 has a double structure, the reaction heat generated in the catalyst 1 (not shown in FIG. 11) is released outside the catalyst rotor 202 by heat transfer. The amount of heat that is lost can be reduced. As a result, waste of reaction heat generated in the catalyst 1 (reaction heat is dissipated to the surroundings by heat transfer) is reduced, and the reaction heat is continuously supplied into the catalyst 1 as a preheating source of unreacted gas ( It is used as an energy source for preheating.

Other configurations and operational effects in the fifth embodiment in FIG. 11 are the same as those in the above-described embodiments.
The configuration according to the fifth embodiment can also be applied to other embodiments.

FIG. 12 shows a sixth embodiment of the present invention.
In each embodiment of FIGS. 1 to 11, the height direction position of the catalyst 1 or the catalyst rotor 2 cannot be changed after the base on which the entire apparatus is placed is determined. In the embodiment, the height direction position of the catalyst 1 or the catalyst rotor 2 (only the catalyst rotor 2 is shown in FIG. 12) is configured to be adjustable.

  In FIG. 12, the drive pin 9 fixed to the member 2 b of the catalyst rotor 2 is inserted into a through hole 8 b formed in the plate-like member 8. In other words, this allows the drive pin 9 to move relative to the plate-like member 8 in the direction of the center line C of the catalyst rotor 2, but when the like-like member 8 rotates in the direction of the center line C. Are attached to rotate together.

Between the apex of the lower end of the curved member 2b and the plate-like member 8, an adjusting mechanism for adjusting the distance between them is configured. The adjusting mechanism includes a bolt 204 and a blind hole 206 drilled at the end of the large-diameter portion 10a of the drive shaft 10 on the catalyst rotor 2 side (upward in FIG. 12). A female screw portion (not clearly shown) that is screwed onto the bolt 204 is formed.
When adjusting the position in the height direction of the catalyst or the catalyst rotor 2, that is, the position in the direction of the center line C, the bolt 204 may be rotated. If the bolt 204 is tightened clockwise, the catalyst rotor 2 moves downward, and if it rotates counterclockwise, the catalyst rotor 2 moves upward.

Configurations and operational effects other than those described above in the sixth embodiment of FIG. 12 are the same as those of the embodiments of FIGS.
And the structure of 6th Embodiment of FIG. 12 is applicable to each embodiment of FIGS.

  Next, a seventh embodiment will be described with reference to FIGS.

  First, with reference to FIG. 13 and FIG. 14, “control during normal operation” of the seventh embodiment, that is, an embodiment in which the rotational speed of the drive electric motor 12 is controlled by a change in exhaust temperature will be described.

In performing “control during normal operation” of the seventh embodiment of FIGS. 13 and 14, the configuration as a base is the same as that of the apparatus of the first embodiment (reference numeral J1 in FIG. 13) as shown in FIG. In this embodiment, the control unit 100 as the control means, the exhaust system line 5 is provided with a temperature sensor St, and the electric motor 12 is provided with a tachometer Sr.
In FIG. 13, reference numeral 200 denotes a printing factory that discharges gas to be processed, for example, reference numeral Li denotes an input signal line, and Lo denotes an output signal line.
The control method will be described below.

  In step S1, the allowable minimum temperature Ta and the allowable maximum temperature Tb are set, and in step S2, the temperature T at the outlet of the casing 3 is measured by the thermometer St.

  In the next step S3, the control unit 100 determines that the measured temperature T is less than the allowable minimum temperature T2 (T <Ta), or the temperature T is equal to or higher than the allowable minimum temperature Ta and equal to or lower than the allowable maximum temperature Tb (Ta ≦ T ≦ Tb) or whether the temperature T exceeds the allowable maximum temperature Tb (Tb <T).

If the measured temperature T is less than the allowable minimum temperature Ta (T <Ta), the process proceeds to step S4, and after the rotational speed of the electric motor 12 is reduced, the process proceeds to step S7.
When the temperature T is equal to or higher than the allowable minimum temperature Ta and equal to or lower than the allowable maximum temperature Tb (Ta ≦ T ≦ Tb), the process proceeds to step S5, the current rotational speed of the electric motor 12 is maintained, and the process proceeds to step S7.
If the temperature T exceeds the allowable maximum temperature Tb (Tb <T), the process proceeds to step S6, and after the rotational speed of the electric motor 12 is increased, the process proceeds to step S7.

In step S7, the control unit 100 determines whether or not to end the control. If it is desired to end the control (YES in step S7), the control unit 100 ends the control as it is.
On the other hand, if it is desired to continue the control (NO in step S7), the process returns to step S1, and steps S1 and after are repeated again.

  Although not described in the control flow (FIG. 14), the rotation speed of the catalyst rotor 2 can always be monitored by the tachometer Sr during operation of the apparatus.

  The reason why the temperature sensor Sr is provided in the exhaust system line 5 is that the exhaust temperature T is a parameter directly connected to the thermal efficiency of the reactor and is easy to measure.

  This is because the concentration on the supply side (inlet side of the reaction apparatus) is measured, and if the concentration on the inlet side is high, the rotation speed can be reduced. However, the mechanism for measuring the concentration is complicated and expensive. Therefore, it is preferable to control at the outlet side temperature that can be easily measured by the relatively inexpensive temperature sensor Sr as in this embodiment.

  Next, with reference to FIG. 15 and FIG. 16, “control for determining presence / absence of catalyst regeneration” of the seventh embodiment will be described.

  As shown in FIG. 15, the configuration of the processing apparatus is different from the apparatus (FIG. 13) in the case of performing the “control during normal operation” described above in that a warning buzzer 300 is added.

  With reference to FIG. 16, the control method of “judgment of presence / absence of catalyst regeneration” will be described.

  In step S11, the control unit 100 first records the exhaust temperature and the rotational speed of the catalyst rotor 2 in the initial stage, that is, in the initial stage when the VOC process is started with a new catalyst or a catalyst immediately after regeneration. The exhaust temperature is measured by the temperature sensor St (step S12).

  In the next step S13, the control unit 100 determines whether or not the rotational speed of the catalyst rotor 2 is slower than a predetermined ratio, for example, 20% or more from the initial stage of the same exhaust temperature. (NO in S13), the loop from Step S12 to Step S13 is repeated, and if the rotation speed is slower than the predetermined ratio (YES in Step S13), the process proceeds to Step S14.

  In step S14, the control unit 100 determines that “catalyst regeneration is necessary”, gives a warning by the buzzer 300 (step S15), and proceeds to step S16.

In step S16, it is determined whether or not the reproduction has been executed. If it has been executed (YES in step S16), the process returns to step S1, and steps S11 and after are repeated again.
On the other hand, if the reproduction is not executed (NO in step S16), the loop of step S15 and step 16 is repeated.

  Next, with reference to FIGS. 17 and 18, “control for judging deterioration of catalyst” in the seventh embodiment will be described.

  As shown in FIG. 17, the configuration of the processing apparatus is different from the apparatus (FIG. 15) used in the above-described “judgment of catalyst regeneration” in that a timer 120 is connected to the control unit 100. A control method of “control for judging deterioration of catalyst” will be described below with reference to FIG.

  First, in step S21, after measuring the exhaust temperature using the temperature sensor St, in step S22, the control unit 100 determines whether the exhaust temperature is equal to or lower than a predetermined temperature.

  If the exhaust gas temperature exceeds the predetermined temperature (NO in step S22), the loop of steps S21 and S22 is repeated. If the exhaust gas temperature is equal to or lower than the predetermined temperature, in step S23 (YES in step S22), the rotation of the catalyst rotor 2 is performed. The number is decreased by a predetermined number of revolutions.

  In the next step S24, the control unit 100 monitors until a predetermined time elapses (loop in step S24). When the predetermined time elapses (YES in step S24), the exhaust gas temperature is measured again (step S25). ).

In step S <b> 26, the control unit 100 determines whether or not the exhaust gas temperature has risen by a predetermined value or more compared to before deceleration.
If the exhaust temperature has not risen above a certain value (NO in step S26), it is determined that the exhaust has deteriorated (step S27).
On the other hand, if the temperature has risen above a certain value (YES in step S26), the process returns to step S1 and repeats step S21 and subsequent steps.

  In the next step S28, a warning is given by the buzzer 300, and the control is terminated.

  Next, with reference to FIG. 19 and FIG. 20, the “counting method of the total processing amount ΣQ” of the processing gas processed by the apparatus of the seventh embodiment will be described.

  As shown in FIG. 19, the configuration of the processing apparatus is such that a flow meter Sq is provided in the air supply system line 4 with respect to the apparatus (FIG. 17) in the case of performing the above-described “control for judging catalyst deterioration”. The only difference is that the buzzer connected to the control unit 100 is changed to the display means 130.

  With reference to FIG. 20, the “counting method of the total processing amount ΣQ” will be described.

    In step S31, the measurement is started by the timer 120, and the control unit 100 determines whether or not the predetermined time ΔT has elapsed (step S32).

  When the predetermined time ΔT has elapsed (YES in step S32), the temperature sensor St reads the exhaust temperature, and the flow meter Sq reads the result on the flow meter side (step S33).

  In the next step S34, the control unit 100 calculates a processing amount Qn for a predetermined time ΔT, and obtains a total processing amount ΣQ by sequentially integrating similar processing amounts for every predetermined time (step S35).

  In the next step S36, the control unit 100 determines whether or not the processing work is finished. If the processing work is finished (YES in step S36), the control unit 100 displays the total processing amount ΣQ on the display means 130. To finish the control. On the other hand, if the process has not ended (NO in step S36), the process returns to step S31, and step S31 and subsequent steps are repeated again.

Next, an eighth embodiment of the present invention will be described with reference to FIGS.
In the eighth embodiment, the amount of heat generated by the reaction of the gas to be processed (untreated gas) such as VOC in the catalyst 1 exceeds the allowable maximum value (upper limit), or the allowable minimum value (lower limit). It is configured to perform control to activate the emergency avoidance means when the value falls below.

In FIG. 21, the exhaust system line 5 is provided with a temperature sensor Std for detecting the exhaust temperature Td, and the intake system line 4 is provided with a temperature sensor Sti for detecting the intake air temperature Ti.
Further, a heater 80 and a blower 82 are interposed in the intake system line 4, and the clean air supply line 4-2 is joined at the junction PG. A flow rate adjustment valve Vca and a flow meter SQA for measuring the flow rate QA in the region 4-1 are interposed in the region 4-1 further upstream from the junction PG (printing factory 200 side).
On the other hand, the clean air supply line 4-2 communicates with a clean air supply source (not shown), and a flow rate adjusting valve Vcb and a flow meter SQB for measuring the flow rate QB in the line 4-2 are interposed.

  The detection signals of the temperature sensors Std and Sti and the flow meters SQA and SQB are sent to the control unit 110 via signal transmission lines SL1 to SL4, respectively. A valve opening control signal (control signal signal for adjusting the flow rate) from the control unit 110 is sent to the flow rate adjustment valves Vca and Vcb via the signal transmission lines SL5 and SL6.

The control of the eighth embodiment will be described mainly with reference to FIG.
First, the flow rates QA and QB in the areas (or lines) 4-1 and 4-2 are measured by the flow meters SQA and SQB, and the exhaust temperature Td and the intake air temperature Ti are detected by the temperature sensors Std and Sti (step S41). Note that, at the beginning of the operation of the reaction apparatus shown in FIGS. 21 and 22, the clean air flow rate QB flowing through the line 4-2 is zero.

Next, the calorific value Q in the catalyst 1 is calculated using the detected flow rates QA and QB and the temperatures Td and Ti in a calculation block (not shown) in the control unit 110 (step S42). Then, it is determined whether or not the calculated calorific value Q is within an appropriate range (step S43).
Here, the appropriate range (or allowable range) of the calorific value is determined on a case-by-case basis depending on the scale of the printing plant 200 where the reaction apparatus is installed, the size of the catalyst 1, and various other conditions. A numerical value that can be determined in advance.

If the calorific value Q is appropriate (Yes in step S43), the reactor throughput is appropriate and there is no need to supply clean air from the line 4-2, so the valve Vcb is closed and the valve Vca is closed. Only the opening degree is adjusted to determine the throughput of the reactor (step S44). Specifically, the opening degree of the valve Vca is adjusted so that the exhaust temperature (exit temperature) Td is maintained higher than the intake temperature (inlet temperature) Ti.
If only the opening degree of the valve Vca is adjusted and the valve Vcb is closed (if step S44 is completed), the process proceeds to step S45.

If the heat generation amount Q is too low with respect to the appropriate range (allowable range) (“Q is too low” in step S43), the VOC processing amount is insufficient and the reaction heat is sufficiently generated in the catalyst 1. Since there is no state, the auxiliary heater 80 is operated (step S46). In this case, since the reaction is insufficient, it is not necessary to supply normalized air, and the valve Vcb is closed.
After operating the auxiliary heater 80, the exhaust temperature (exit temperature) Td and the intake air temperature (inlet temperature) Ti are measured (step S47), and if the exhaust temperature Td does not become higher than the intake air temperature Ti (step S48). No), the auxiliary heater 80 continues to operate (the loop in which step S48 is No).

If the exhaust temperature Td is higher than the intake air temperature Ti (Yes in step S48), the auxiliary heater 80 is stopped (step S49), and the process proceeds to step S45.
By the control in steps S46 to S49, it is possible to cope with an abnormal situation in which the amount of heat generated in the catalyst 1 is lower than the allowable range.

If the heat generation amount Q is too high with respect to the permissible range (“Q is excessive” in step S43), the VOC processing amount is excessive and the reaction heat in the catalyst 1 is excessive. And supply clean air into the reaction path 1 via the line 4-2 to reduce the VOC concentration of the gas to be treated and reduce the opening of the valve Vca so that the VOC enters the catalyst 1. The amount to be supplied is decreased (step S50).
Then, the exhaust temperature Td and the intake air temperature Ti are measured (step S51).

If the reaction heat in the catalyst 1 is large, the temperature difference between the exhaust temperature Td and the intake air temperature Ti becomes large. If the reaction heat in the catalyst 1 is within an appropriate range, the temperature difference between the exhaust temperature Td and the intake air temperature Ti is also less than an allowable value (as determined by the case-by-case as in the allowable range of the heat generation amount Q). It becomes.
In step S52, it is determined whether or not the temperature difference between the exhaust temperature Td and the intake air temperature Ti is less than or equal to an allowable value. If the difference is greater than or equal to the allowable value (No in step S52), the heat generation amount Q is still excessively large. It is determined that there is, and the process returns to step S50.

On the other hand, if the temperature difference between the exhaust temperature Td and the intake air temperature Ti is equal to or less than the allowable value (Yes in step S52), it is determined that the heat generation amount is not excessive, and the process proceeds to step S45.
By controlling the steps S50 to S52, it is possible to cope with an abnormal situation in which the reaction heat in the catalyst 1 becomes excessive.

  In step S45, it is determined whether or not the operation of the reaction apparatus is finished and the control is finished. If the operation is continued (No in step S45), the process returns to step S41 and the above-described control is repeated.

  The control in the eighth embodiment described with reference to FIGS. 21 and 22 can be executed in combination with the above-described embodiments.

Next, a ninth embodiment of the present invention will be described with reference to FIG.
In the first to eighth embodiments, the generated heat quantity is effectively utilized by the reaction device J1 that supports the reaction of the gas to be treated (untreated gas) such as VOC by the catalyst 1, but this reaction device J1. The purified exhaust gas discharged from the air is discharged to the atmosphere while having a calorific value of 200 to 250 ° C., for example.

  Further, there is a possibility that unreacted (unburned) gas exists in the exhaust gas discharged from the reactor J1.

  In the ninth embodiment, the exhaust gas discharged from the reaction device J1 is reacted again (burned) by the stationary reaction device, so that the VOC can be further removed.

  In FIG. 23, the factory 200 and the reactor J1 are connected by an air supply system line 4, and a heater 80 capable of controlling the heating amount is interposed in the air supply system line 4, and communicates with the heater 80 and the upper part of the catalyst 1. A temperature sensor 4 c is interposed in the air supply system line 4.

  Further, the reactor J1 and the fixed reactor Rs are connected by a discharge line 5, and a heater 90 capable of controlling the heating amount is interposed in the discharge line 5, and the discharge line 5 leading to the heater 90 and the upper part of the catalyst 1. The temperature sensor 5c is interposed between the heater 90 and the discharge line 5 leading to the inlet side of the stationary reactor Rs.

  The stationary reactor Rs is similar in material and function to the catalyst 1 of the reactor J1 according to the first to eighth embodiments. For example, a platinum catalyst is used, and the shape, size, and lamination of the catalyst are arranged. It is set according to the properties of the gas passing through the stationary reactor Rs. A discharge pipe R5 is connected to the outlet side of the fixed reactor Rs, and a temperature sensor 5e is interposed near the fixed reactor Rs of the exhaust pipe R5.

The heater 90 is configured to have a function and a capacity capable of starting the reaction of the VOC exhaust gas containing the unreacted components discharged from the reaction device J1 with the stationary reaction device Rs or supplying a heat amount sufficient to continue the reaction. ing.
The configuration other than the above is substantially the same as that of the first embodiment.

With reference to FIG. 23 and FIG. 1 of the first embodiment, the operation of the ninth embodiment having the above configuration will be described mainly with respect to portions different from the first embodiment.
The VOC gas discharged from the factory 200 is supplied to the reactor J1 through the supply system line 4 and led to the supply side 32I divided by the partition wall 6 and the separator 7 above the catalyst 1.
The VOC gas descends the path 1a from the upper part of the area of the catalyst 1 existing on the intake side 32I, and the exothermic reaction of VOC is started by the catalytic action while descending.

  In the region of the catalyst 1 that has reached the exhaust side 32E (rotating the catalyst 1), the exothermic reaction continues to become high temperature while the VOC that has entered the path 1a and has undergone the exothermic reaction rises. As a result, the VOC is purified and reaches the upper space of the catalyst 1 on the exhaust side 32E. Then, it flows through the discharge line 5.

The gas (reacted gas) discharged (purified) from the exhaust side 32E to the discharge line 5 is directed to the stationary reactor Rs.
In the stationary reactor Rs, the unreacted VOC remaining in the reaction gas cleaned and discharged in the discharge line 5 is reacted again using, for example, a heat amount of 200 ° C. held by the reaction gas at the time of discharge. .
In the stationary reactor Rs, the VOC remaining in the reaction gas can be reliably reacted and cleaned. And since such reaction can be performed using the amount of heat held by the reaction gas, the energy consumed in the stationary reactor Rs is relatively small.

  Here, a temperature sensor 5e is interposed in the discharge line RS of the stationary reactor Rs, and the reaction state in the stationary reactor Rs is the temperature of the gas after the reaction (line RS) measured by the temperature sensor 5e. The reaction gas temperature flowing through the Although not shown in FIG. 23, a control unit may be provided to control the amount of heat supplied from the heater 90.

  More specifically, the amount of heat supplied from the heater 90 is the same as the amount of heat supplied from the heater 80 to the reactor J1, and is controlled by a control unit (not shown) according to the reaction status of the stationary reactor Rs. The temperature is controlled by considering the detected temperature Td2 of the temperature sensor 5d and the detected temperature Td3 of the temperature sensor 5e as parameters.

It should be noted that the illustrated embodiment is merely an example, and is not a description to limit the technical scope of the present invention.
For example, if the catalyst is rotatable, Pt need not be supported on the ceramic.
It is also possible to implement a combination of a plurality of the above-described embodiments simultaneously.

The present invention can also be applied to a place where smoke is produced, a smoking area or other air purification.
It is possible to apply the exhaust heat of the reactor of the present invention (the amount of heat / exhaust heat possessed by the treated clean gas exhausted from the catalyst / 200 ° C.) to dry garbage.
