Description

  The present invention has an internal structure partitioned into a large number of flow paths, and includes a liquid distributor disposed at an upper portion and a liquid collector disposed at a lower portion, and mass transfer, heat exchange or mixing between a gas and a liquid. The present invention relates to a gas-liquid contact mechanism in a device that performs the above.

  Conventionally, a regular filler as shown in a partial sectional view in FIG. 18 is known as a regular filler in this type of apparatus. This regular packed body a is formed of a porous thin plate that is formed into a plurality of corrugated shapes and alternately stacked at a predetermined interval below a liquid distributor disposed at the upper part of a packed packed column constituting the apparatus. The sheets b are arranged parallel to each other so as to extend in the diagonal direction of the corrugation, and are arranged in multiple layers so as to be inverted in the reverse direction and extended in the diagonal direction at the position contacting the inner wall of the packed tower. It will be. The liquid that freely falls as droplets from the liquid distributor flows down along these thin sheet sheets b and wets the surface of the sheet b. On the other hand, the gas enters and rises from the gas inlet at the bottom of the tower, passes through the regular packing a, and exits from the gas outlet at the top of the tower. While the gas passes through the regular packing a, gas-liquid contact is performed, and desired mass transfer, heat exchange, or mixing is performed.

  The problem with the conventional ordered packed body is that, firstly, a part of the sheet b constituting the ordered packed body a contacts the inner wall c of the packed tower at its bent edge. The liquid flowing down through these sheets b moves to the inner wall c, and a large portion of the liquid flows back along the inner wall c as a wall flow without returning to the sheet b. On the other hand, the gas rising in the packed tower has a parabolic flow velocity distribution in the radial direction of the cross section, the flow velocity at the center is the fastest, and when approaching the wall surface, the flow velocity approaches zero due to viscosity. Therefore, the rising gas tends to flow through the center of the tower, and almost no gas flows through the wall surface. Due to this gas drift, the wall flow of the liquid is less in contact with the gas than the liquid flowing in the center, resulting in non-uniformity in the reaction to be achieved as a result of non-uniform gas-liquid contact.

  The second problem of the conventional regular packing body is that in this regular packing body a, the sheet b is arranged obliquely, so that the pressure loss is high, the energy consumption is correspondingly high, and the efficiency is low. is there.

  The third problem of the above-mentioned conventional regular packing is that the upper limit of the gas load is kept relatively low because the device cannot be operated soundly when the gas load is increased.

  That is, when the flow rate of the liquid supplied from the liquid distributor at the top of the tower is increased, the descending liquid gets wet while spreading the surface of the packing, but when the liquid volume is further increased, the liquid film becomes thicker and partially Leaves the liquid film as droplets. Therefore, if the flow rate of the gas added from the lower part of the tower is increased while the liquid is flowing from the top, the liquid film surface is easily disturbed by the high gas flow velocity and becomes droplets, which are blown upward by the gas.

  As a result, a certain component is concentrated and the descending liquid is caused to flow backward, and the reaction efficiency is deteriorated. The phenomenon that the gas blows off the droplets is often seen until the liquid falls from the liquid distributor at the top of the tower to the top of the regular packing or in the vicinity of the liquid collector provided at the bottom of the tower. For example, it behaves like raindrops from rain gutters blown in all directions by strong winds during typhoons. The liquid distributor is for supplying the liquid uniformly to the regular packed body in the cross-sectional direction of the tower, and the above behavior that blows off the droplets lowers the performance of the packed tower, and therefore must be prevented as much as possible. On the other hand, the liquid collector must collect the separated liquid without blowing it upward as droplets. The above-mentioned conventional apparatus is an effective countermeasure against the scattering and blowing up of liquid droplets in the space between the liquid distributor and the regular packing body and between the regular packing body and the liquid collector due to the increase in the gas flow rate. Does not have.

  Regarding the third problem, a liquid distribution / collection mechanism described in Patent Document 1 has been proposed to solve this problem. In this mechanism, as shown in FIG. 19, a liquid distribution rope h formed by twisting a plurality of strand portions m to a nosul g of a liquid distribution pipe f attached to a liquid distributor e of a packed tower d is connected. The liquid distribution rope h is connected to the regular filler i. The liquid is distributed from the liquid distribution pipe f to the regular packing body i through the liquid distribution rope h and the strand part m branched in two, and the liquid which has completed the gas-liquid contact is formed by twisting a plurality of strand parts n. The liquid collecting mechanism k including the liquid collecting rope j is transferred to the liquid outlet l. Therefore, in this apparatus, the liquid is expected to be reliably transferred to the regular packing body and taken out from the regular packing body without being blown upward even at a high gas velocity.

  This liquid distribution / aggregation mechanism seems to be an ideal liquid distribution method that solves the third problem in theory, but as a result of the experiment, the two strand portions m constituting the liquid distribution rope h are Even if it is composed of the same number of wires, it flows through each wire first due to a slight twist angle difference between each wire or a difference in the compatibility of liquid based on the difference in surface roughness of each wire. The flow of liquid is not uniform for each wire, and the wire that flows most easily has a liquid path ahead of the other wires, and the subsequent liquid follows and does not flow along the other wires. Since there is a tendency, the liquid flowing from the liquid distributor to the liquid distribution rope h does not necessarily flow evenly to the two strand portions m branched from the liquid distributor, and as a result, the liquid flowing to the regular packing i also becomes non-uniform and complete. Gas-liquid contact It was found that can not be.

  As an apparatus for solving the above-mentioned problems, Patent Document 2 is a regular packing body that constitutes an internal structure, and is composed of a plurality of packing body constituent elements. Each packing body constituent element includes an inner wall of the apparatus and an adjacent packing body. A regular filler that extends vertically in parallel with each other in a non-contact state with a component, and a plurality of adapters that connect the liquid distributor and the regular filler and supply liquid from the liquid distributor to the regular filler And a plurality of collectors that connect the liquid collector and the regular filler and supply liquid from the regular filler to the liquid collector. According to this device, each filler component extends vertically in parallel to each other in a non-contact manner with the inner wall of the device and adjacent filler components, so that it flows down from the liquid distributor to each filler component. The liquid moves to the inner wall of the apparatus and does not flow into the wall, and moves to the adjacent packing component and flows to the liquid collector without causing a non-uniform liquid flow. As a result, the amount of liquid flowing through each filler component is uniform, and uniform gas-liquid contact is achieved. In addition, since each filler component extends in the vertical direction in the apparatus, pressure loss can be minimized. Furthermore, since the liquid distributor and the regular packing are directly connected by an adapter, and the regular packing and the liquid collector are also directly connected by the collector, the liquid distributor is regularly connected to the regular packing by the increase in the gas flow rate. It is possible to prevent the droplets from being scattered and blown up in the space between the filler and the liquid collector.

  In order to further improve the gas-liquid contact performance in this gas-liquid contact mechanism, the present applicant has proposed a gas-liquid contact mechanism according to Patent Document 3.

  This gas-liquid contact mechanism has an internal structure that partitions a large number of flow paths between a liquid distributor disposed at the upper part of the apparatus and a liquid collector disposed at the lower part of the apparatus. In an apparatus for mass transfer, heat exchange or mixing, a regular packing constituting the internal structure, comprising a plurality of packing body components, each packing body component comprising an inner wall of the apparatus and an adjacent packing body configuration A regular packing body extending in a vertical direction in parallel with each other in a non-contact state with each of the elements, each of the packing body components comprising two or three wires, each of the two or three wires being a ring shape It has the structure where a part and a gathering part repeat alternately.

  Each filling body component constituting the gas-liquid contact mechanism is composed of two or three wires, and each of the two or three wires has a structure in which a ring-shaped portion and a collecting portion are alternately repeated. The liquid flowing down along this becomes a thin liquid film covering the circular space in the ring at the ring-shaped portion, and the surface area of the liquid is maximized, and the effect of contact with the gas is increased. Then, the liquid is collected. By repeating this operation continuously, the liquid film was renewed and a good gas-liquid contact effect was achieved.

It can also be fixed by a method of tightening 20 from the outside.

Next, the operation of the gas-liquid contact mechanism using the filler component 6 will be described with reference to FIGS.
According to the above embodiment, each filling body component 6 constituting the gas-liquid contact mechanism is composed of three wires 6a, 6b, and 6c, and the two wires 6a and 6b are respectively a ring-shaped portion 15 and a collecting portion. 17 has a structure that repeats alternately, so that the liquid flowing down through this becomes a thin liquid film covering the circular space in the ring in the link-shaped portion 15, the surface area of the liquid is maximized, and the gas rising from below The most effective contact will be made. Next, the liquid forming the liquid film flows down from the ring-shaped part 15 of the wire to the concentrating part 17 directly below, and after collecting the liquid here, it flows down to the ring-shaped part 15 immediately below to cover the inner space of the ring again. A liquid film is formed, and thereafter this operation and shape change are repeated alternately. In this way, the liquid film is renewed successively and an excellent gas-liquid contact effect is achieved.

  Further, since the streaky wire has no branching in the middle, there is little pressure loss. Also, the high performance results in very low pressure loss for performance.

  Moreover, according to the embodiment which uses the filling body component 6 which consists of the said 3 wire, since the linear 3rd wire 6c is arrange | positioned in the middle of the outer 2 wire which forms a ring, The third wire 6c reinforces the ring and exhibits a function of preventing the circular liquid film from being damaged, thereby enabling more efficient gas-liquid contact.

  Further, the horizontal filament 20 has a strong capillary force and constantly holds a certain amount of liquid. And a liquid mixes in a coupling | bond part with each filling body component, and changes gradually. Therefore, the liquid held in the horizontal direction can effectively obtain the gas-liquid contact effect for a long time with the rising gas. In addition, by installing the horizontal filaments 20 at optimum intervals in the vertical direction, the maximum gas-liquid contact effect, that is, the maximum performance can be obtained.

  In addition, the horizontal filament 20 not only retains the liquid for a long time, but also intersects the numerous filler components 6 at many locations and mixes the liquid at those locations. It also has the effect of averaging the vertical liquid flow, and contributes to further performance improvement.

  On the other hand, in terms of the structure of the product, an ideal three-dimensional structure can be obtained by adding a large number of horizontal lines 20 to the packing member 6 in the vertical direction, and transporting the product as compared with the case where only the spacer 19 is provided. , And effects useful for installation in the apparatus can also be obtained.

  In addition, although the spacer 19 which connects a plurality of filling body components 6 in the horizontal direction is also a filament extending in the horizontal direction, the spacer 19 is a monofilament, that is, a single wire that is not a twist of a plurality of wires. Therefore, the liquid flowing down each filler component 6 is not provided with a function of holding the liquid for a long time or flowing it to the adjacent filler component. The horizontal filaments of the present invention can hold the liquid for a long time, and the liquid can be mixed at the intersection with the filler component because the horizontal filaments are stranded or coherent double filaments. This is because the liquid flowing down each filler component can be sucked by capillary action, which is completely different from the spacer in terms of function.

  Note that the present invention can also be applied to a gas-liquid contact mechanism that does not include the adapter and collector as shown in FIG. 1 and that has a structure in which a plurality of filler components hang directly from the liquid distributor.

The liquid flow flowing along the inner wall 10a of the tower is operated so as to flow into each packing component 6. In the embodiment of FIG. 5, since the adapter 4 is provided, most of the liquid flow flows from the adapter 4 to each packing component, but a small portion of the liquid flow scatters around and travels along the inner wall 10a of the tower. Since the liquid flows down, the liquid-liquid contact efficiency can be further improved by collecting the liquid flow and collecting it in the horizontal line 20.

  The embodiment of FIG. 6 is a modification of the embodiment of FIG. In this embodiment, an adapter and a collector are not provided, and the ratio of the liquid droplets from the liquid distributor 2 splashing and flowing along the tower inner wall 10a is larger than that in the embodiment of FIG.

In this embodiment, since the liquid flowing down each packed body component 64 is formed in a polygonal line shape, it flows slowly, and a part of the flow is retained by the horizontal filament 65 and stays in the tower as a whole. Therefore, the time for gas-liquid contact becomes longer and the gas-liquid contact efficiency can be increased.

A vertical line 72 hangs down through a hook (not shown). Horizontal lines 73 that connect the vertical lines 72 in the horizontal direction are arranged at appropriate intervals in the vertical direction. The plurality of vertical lines 72 and the horizontal lines 73 form a reticulated filler component 74. One liquid distributor 70 is connected on both sides so that a mesh-like filler component 74 hangs down, and is supplied with liquid. Each vertical line 72 and horizontal line 73 is preferably composed of a stranded wire or a double contact wire.

  In each net-like filler component 74, the filaments A1, A2 and B1, B2 made of stranded wires or double contact wires are arranged in the vertical direction at appropriate intervals so as to extend in the horizontal direction. The strips A1 and A2 are fixed to the mesh-like filler components 74 on both sides thereof by a suitable method such as clips. The diameter of each horizontal line is set to substantially the same value as the width of the liquid distributor 70, and is preferably about 5 mm to 10 mm, for example.
