Description

  The present invention is one of incinerators for combusting organic waste, and a magnetic powder production apparatus for producing (generating) magnetic powder by combusting organic waste in a magnetic atmosphere. It relates to a manufacturing method.

  In general, the main purpose is to incinerate garbage such as garbage and waste materials in the combustion path. Many waste disposal methods for burning combustible waste have been put to practical use so far, but the main purpose is to burn the waste. For this reason, in order to reliably prevent incomplete combustion of waste, combustion at high temperatures is indispensable. As a result, it is necessary to increase the size of the processing apparatus, and high operating costs are required.

  For this reason, a low temperature incinerator may be used. Some of these low-temperature incinerators are burned with magnetic air (hereinafter referred to as magnetized air bodies).

  These low-temperature incinerators are ignited with a gas burner from the outlet. After ignition, magnetic carbide is completed in a few weeks.

  For example, Patent Document 1 (Japanese Patent Laid-Open No. 2001-304520) discloses an incinerator that incinerates combustible waste by using air that has activated oxygen or the like in the air by influencing the combustion air with the influence of a magnetic field. There has been proposed an incinerator capable of facilitating the combustion of waste by using it and enabling incineration at a low temperature (Patent Document 1).

  The incinerator of this patent document 1 is comprised including the incinerator main body and the flue water tank, and while burning the incineration processed material in the incinerator main body 12, the combustion gas generated by combustion is flue water tank It is sent to the outside through a pipe. And this pipe is led in the water of the water tank. This suppresses the smoke emitted from the water and diffuses the substances contained in the smoke into the water.

  Further, Cited Document 2 (Japanese Patent Application Laid-Open No. 2007-682) discloses an air tube provided with an air tube around the lower portion of the heating furnace, and a magnetic field generator provided with a magnet around the air tube. The waste in the heating path is smoked to turn the waste into magnetic carbide (also called magnetic powder). And smoke is guided to the water tank by an air pipe provided in the upper part of the heating furnace. A magnetism generator is also provided around the air pipe. This is because the cooling water in the water tank is activated by the magnetism of the exhaust gas and the oil removal efficiency is improved.

Further, Cited Document 3 (Japanese Patent Application Laid-Open No. 2006-86307) discloses that air pipes are provided around the lower part of the heating furnace, and a magnetic field generator provided with magnets is attached around the air pipes. Waste in the heating path is changed to magnetic carbide (hereinafter simply referred to as magnetic powder). And smoke is guided to the water tank by an air pipe provided in the upper part of the heating furnace.

  However, since Cited Document 1, Cited Document 2 and Cited Document 3 ignite the waste in the heating furnace with a gas burner, it takes time to ignite the entire waste surface in the heating furnace. Cost.

  In addition, since humans ignite with gas burners, it is dangerous when the heating furnace becomes large, smoke is generated because the lid is opened and ignition is performed by the bus burner, and smell is also emitted when there is a lot of smoke from the heating furnace. It was.

  In other words, the dioxin concentration in the flue gas of the combustion gas exhausted to the outside increases, which may harm the global environment. Furthermore, in any case, a bad odor is generated by exhausting the combustion gas exhausted to the outside of the furnace vessel, which may harm the environment around the incinerator.

  Further, Cited Document 1, Cited Document 2, and Cited Document 3 are used to guide the exhaust smoke from the heating furnace to the aquarium with an air pipe and erase the smoke. However, the water in the aquarium becomes dirty and the water in the aquarium is cancelled. This means that water cannot be easily discarded due to environmental conservation issues.

  That is, each cited document hardly existed except for the removal of the flue gas generated at the time of burning organic waste, except for water.

  Therefore, the magnetic powder manufacturing apparatus using waste can manufacture magnetic powder as soon as possible without igniting the waste in the heating furnace by using a gas burner or the like, and by eliminating smoke coming out of the heating path. Is desirable.

  That is, an object of the present invention is to obtain a magnetic powder manufacturing apparatus and a manufacturing method thereof using waste that can easily and safely ignite waste in a heating furnace and can produce magnetic powder without generating smoke. To do.

  An exhaust pipe unit (exhaust pipe) 108 for exhausting combustion gas (including smoke) generated by the combustion of organic waste to the outside of the furnace container 63 is provided on the top wall of the furnace container 63.

  As shown in FIG. 13, the exhaust pipe unit 108 connects the exhaust pipe 108 a connected to the furnace furnace 63, the first stage exhaust combustion box 105, and the second stage exhaust combustion box 107. Exhaust pipe 108b and exhaust pipes 108c, 108d, 108e (about 150 mmφ) for discharging combustion gas from the exhaust port 119 to the outside from the second stage smoke combustion box 107, brackets 106a, 106b, 106c, etc. Connected with.

  That is, the flue gas combustion unit 103 composed of the flue gas combustion boxes 105, 107 at each stage communicates with the flow path of the exhaust pipe unit 108. Further, the wall portions of the smoke exhaust combustion boxes 105 and 107 at each stage have a double wall structure (see FIG. 8) having an inner peripheral wall and an outer peripheral wall.

  Inside the first-stage flue gas combustion box 105 and the second-stage flue gas combustion box 107, a rod-shaped smoke electric heater (electric gas for flue gas) that burns the flue gas of the combustion gas by electric heating. (Heat wire) 109 and 111 (an example of a smoke heater) are provided, and the heating temperature of each smoke heater 111 (107) is a high temperature of 400 to 800 ° C. (preferably about 700). Thus, electric heating is performed at a temperature higher than that of the plurality of waste electric heaters 93. A temperature sensor may be provided inside the two-stage exhaust smoke combustion boxes 107 and 105.

  Further, the structure of the combustion box 105 for the first stage smoke emission is the same as that of FIG. 8, and has an inner diameter of 300 mmφ (wi side) and an outer shape of 400 mmφ (wo side), as shown in FIG. The cylindrical shape is formed. The height is about 600 mm.

  Further, as shown in FIG. 17 (b), the smoke exhaust electric heater 109 inserted in the first stage smoke exhaust combustion box 105 is composed of two spiral heating wires 109a and 109b. The heating wire 109a is incorporated in the heating wire 109b. These heating wires are covered with a steel mesh 109c of 1 mm mesh (may be 2 mm, 3 mm, 5 mm, 8 mm, and 10 mm). The mesh 109c may be two iron nets covering the outer heating wire and the inner heating wire.

FIG. 17C is a cross-sectional view of the main body, and FIG. 17D is the socket side.

  That is, the smoke is burned by the inner heating wire and the outer heating wire, and the iron braid 109c is heated, so that the smoke is further burned when passing through this mesh.

  On the other hand, the configuration of the second stage smoke combustion box 107 is the same as that shown in FIG. 8, with an inner diameter of 200 mmφ (wi side) and an outer diameter of 300 mmφ (wo side), as shown in FIG. The cylindrical shape is formed. The height is about 400 mm.

  As described above, the first-stage flue gas combustion box 105 and the second-stage flue gas combustion box 107 are different in size and heating wire from the first-stage flue gas combustion box 105. The inside chamber has a diameter of φ300, and the inside diameter of the chamber inside the second stage smoke exhausting combustion box 107 is φ200, so that smoke accumulates on the first stage side. This is burned by the smoke exhaust electric heater 109 (about 700 degrees), and this gas flows to the exhaust port side. However, since the size of the room inside the second-stage smoke emission combustion box 107 is φ200, smoke passes through a narrow passage in the second stage. The passage has a smoke exhaust electric heater 111 having a diameter of φ150, and the second stage smoke combustion box 107 has a smoke outlet, so oxygen is covered from the first stage, so the smoke is completely Will burn.

  Then, the effect | action and effect of 2nd Embodiment are demonstrated.

  Organic waste is introduced from the inlet 71 g of the hopper 71 and stored in the hopper 71. Then, when the shutter 75 is moved forward by the rotation operation of the operation shaft 79 (in other words, the rotation operation of the operation handle 81) and the opening 63a of the furnace vessel 63 is opened by the shutter 75, the organic waste is removed by the hopper. 71 can be supplied to the combustion chamber 65 of the furnace vessel 63.

  After supplying the organic waste to the combustion chamber 65 of the furnace vessel 63, the shutter 75 is moved backward by the rotation operation of the operation shaft 79, and the opening portion 63 a of the furnace vessel 63 is closed by the shutter 75.

  A plurality of air heaters for wastes are supplied to the combustion chamber 65 of the furnace vessel 63 while the magnetic air is supplied to the combustion chamber 65 of the furnace vessel 63 by the plurality of air pipe units 95 with the first magnets and the plurality of air pipe units 99 with the second magnets. By the operation of 93, the organic waste in the combustion chamber 65 of the furnace vessel 63 is electrically heated (350 to 500 degrees: 400 degrees is preferable) and ignited.

  As a result, the organic waste can be dried, carbonized and incinerated sequentially to produce (generate) magnetic powder from the organic waste. The waste electric heater is operated only in the initial stage of combustion of organic waste (for example, 1 hour to 3 hours: preferably about 1 hour from the start of heating).

  On the other hand, the combustion gas (including smoke) generated by the combustion of the organic waste is exhausted to the outside of the furnace vessel 63 by the exhaust pipe unit 108. Here, the exhaust unit 108 is provided with a first-stage exhaust combustion box 105 and a second-stage exhaust combustion box 107 (see FIGS. 17 and 18) in the middle. The flue gas of the combustion gas is electrically heated and burned.

  Here, the reason for using the electric heater for smoke emission will be described. A spiral heating wire as shown in FIG. 9 is used for the first stage smoke combustion box 105 and the second stage smoke combustion box 107 because the temperature of the smoke combustion unit 103 is about 700 degrees n high. State. To maintain this temperature, propane gas will be digested in tens of minutes. In addition, the magnetic powder manufacturing apparatus often heats organic matter in the mountains relatively more than the area where city gas is gasified. For this reason, it heats with an electric wire. Moreover, since the heating wire is spiral as shown in FIG. 9, smoke passes along the spiral heating wire. For this reason, smoke is more likely to burn.

  FIG. 19 is an explanatory view for explaining the operation of the magnetic powder production apparatus according to the present embodiment. In FIG. 19, a predetermined amount of dry organic waste (amount of 1/9 or less when the combustion chamber is 1600φ) is put into the inner furnace 63, and a predetermined amount of organic waste (not dried) is put into the hopper 71. (FIG. 19a).

  In such a state, the plurality of waste electric heaters 93 are turned on and heated for about 1 hour to 3 hours (in the experiment, about 1 hour, but may be dried and burned immediately).

  When starting to catch fire, the plurality of waste electric heaters 93 are turned off (c). When the fire starts, the temperature of the furnace vessel 63 rises (b). At this time, since there is about 20 cm between wi and wo, the outside air is not transmitted into the furnace. In addition, the first-stage exhaust smoke combustion box 105 and the second-stage exhaust smoke combustion box 107 are turned on.

  In this state, magnetized air flows into the organic combustion product in the furnace vessel 63 from the air supply pipe unit 95 with the first magnet, and the internal combustion is activated and burned by this magnetism.

  This combustion passes through the first-stage exhaust combustion box 105 and the second-stage exhaust combustion box 107, but the temperature is set to 600 degrees to 800 degrees, so that the smoke burns. Therefore, it is possible to sufficiently and reliably prevent the flue gas of the combustion gas from being discharged outside the furnace vessel 63. In addition, about temperature, it is good to adjust the electric current which flows into a heating wire with a controller, observing the condition of smoke.

  Burn in this state for about 1 to 2 weeks (d). In general, in the experiment, organic waste was incinerated in about 2 weeks (e). When incinerated, the first-stage flue gas combustion box 107 and the first-stage flue gas combustion box 105 are turned off for about one week (f).

  A controller (not shown) may control such processes a to f.

Even in this state, ash powder continues to be magnetized because the magnetic air enters the inner furnace (g).

  Then, when the temperature drops, the ash powder is taken out as magnetic powder (h).

  In addition, according to the second embodiment, since the organic waste can be burned in the combustion chamber 65 of the furnace vessel 63 to produce magnetic powder from the organic waste, the furnace vessel 63 and the like are extremely excellent in heat resistance. It does not need to be made of a high temperature material. In addition, it is possible to sufficiently and reliably prevent combustion gas flue gas from being discharged to the outside of the furnace vessel 63, so that generation of dioxins and off-flavors during operation of the magnetic powder production apparatus 61 is sufficiently and reliably suppressed. be able to. Therefore, the environmental conservation of the magnetic powder manufacturing apparatus 61 can be easily enhanced while reducing the material cost of the magnetic powder manufacturing apparatus (incinerator) 61.

(Modification of the second embodiment)

Is attached.

As shown in FIG. 20, a bypass pipe 113 is connected between the exhaust pipe 108b and the exhaust pipe 108e connected to the second stage smoke combustion box 107. The bypass pipe 113 has a first bypass pipe 113a connected to the exhaust pipe 108b, a switch 120D connected to the first bypass pipe 113a, and a second bypass pipe 113b connected to the switch 120D.

  A third-stage smoke combustion box 115 is connected to the second bypass pipe 113b. Furthermore, a third bypass pipe 113 c is connected to the third stage exhaust combustion box 115, and a fan 117 with a motor is connected to the third bypass pipe 113.

  A fourth bypass pipe 113e is connected to the motor-equipped connecting fan 117, a switch 120B is connected to the fourth bypass pipe 113e, and the switch 120B is connected to the exhaust pipe 108e by a fifth bypass pipe 113f. .

  Further, a switch 120A is provided at the tip of the exhaust pipe 108e, and a switch 120C is provided between the first-stage smoke combustion box 105 and the exhaust pipe 108b.

  That is, in the present embodiment, smoke that has not disappeared in the second stage smoke combustion box 107 is fed back, and the third stage is heated again (600 to 800 degrees) in the abnormal combustion box 115. It returns to the combustion box 107 for 2nd stage smoke emission.

  At this time, it is preferable to control the opening and closing of each switch. This opening / closing control is preferably performed automatically by a controller (not shown).

  The third stage smoke combustion box 115 may be a heating wire or a gas.

  For some reason (for example, when the inside of the furnace vessel 65 is cooled, the power to the heating wire is reduced, or when the lid is opened halfway), smoke may be emitted. It is preferable to make it function in such a case.

  FIG. 21 is a schematic configuration diagram of a switch. As shown in FIG. 21, a quarter-circular valve case 131 is interposed in the exhaust pipe 108 or the bypass pipe 113, and a tear-like valve 133 is provided in the quarter-circular valve case 131. Provided. A stand 135 for supporting the motor 134 is provided on the exhaust pipe 108 or the bypass pipe 113. The table 135 is preferably heat resistant.

  The fulcrum of the tear-like valve 133 is connected by a drive shaft 132, and a gear 133 (having good heat resistance) for rotating the drive shaft 132 and a motor gear 134 are coupled.

22 is a cross-sectional view of the switch of FIG. As shown in FIG. 22, the teardrop-shaped valve 133 is sandwiched between heat insulating members 136 and 137 for shielding smoke.

  FIG. 22 is an explanatory diagram for explaining the movement of the tear-like valve 133. As shown in FIG. 22, the tear-like valve 133 can close or open the exhaust pipe 108 or the bypass pipe 113 by the rotation of the motor 134.

  FIG. 23 is an explanatory diagram illustrating the opening / closing operation of the switches 120A to 120D of the present embodiment.

  For example, when the state shown in FIG. 23A is the initial state, when smoke is generated or when it is determined that smoke is likely to be generated, the switch is controlled as shown in FIG.

  The ratio of the opening and closing may be determined by determining the amount of opening and closing of the controller and the time for the operator to open and close the controller by looking at the smoke output.

  For example, in FIG. 23B, the fan 117 is rotated in a direction to return the smoke from the exhaust pipe 108e to the exhaust pipe 108b, and the heating wire of the third stage smoke combustion box 115 is turned on. Or gas is burned. In this state, the switch 120A is closed by, for example, about 50%, 120B is opened by 100%, 120C is closed by 80%, and 120D is opened by 100%.

  As a result, smoke in the exhaust pipes 108e, 108d, and 108c flows to the bypass pipe side and outside air enters. This outside air is cold but contains oxygen. For this reason, combustion in the third stage exhaust combustion box 115 is helped, and the smoke is burned and warmed, and then goes to the second stage exhaust combustion box 107 again to be burned. The reason why 120C is closed to about 80% is to let out smoke generated in the furnace vessel 65 and to assist combustion in the furnace vessel 65. Thereafter, the control is performed at the ratio shown in FIG.

  In the above-described embodiment, the air-feeding pipe unit 95 with the first magnet or the air-feeding pipe unit 99 with the second magnet is a magnet, but it may be an electric magnet (consisting of a coil and an iron core). When an electromagnet is used, it is controlled by an external controller (not shown).

  Furthermore, in the said embodiment, although the air supply pipe 97a was provided in the inner wall and the outer wall in parallel, you may make it diagonal. This will prevent tar from going outside.
