Description

  The present invention belongs to a technical field related to an organic matter processing apparatus that thermally decomposes organic matter such as wood and synthetic resin material.

  Recently, a treatment technique for thermally decomposing organic substances at a relatively low temperature has been developed, and organic wastes can be disposed of without generating harmful substances such as dioxins. In this treatment technique, an organic substance is put into a treatment tank in which outside air is blocked, the organic substance is heated, and air (magnetized air) magnetized to the treatment tank is suppressed. Magnetized air has a characteristic of causing a violent thermal decomposition reaction with organic carbon molecules because oxygen is activated by a magnetic force to generate a large amount of negative ions. As a result, the organic matter is oxidatively decomposed into water, ash (inorganic matter, carbon, etc.) and gas (carbon dioxide, hydrocarbon, etc.).

  In order to configure an apparatus that realizes this processing technique, it is necessary to develop a technique for controlling the suppressed supply of magnetized air to the processing tank.

  Conventionally, as an organic substance processing apparatus provided with the technique which controls the suppression supply of the magnetized air with respect to a processing tank, the thing of patent document 1 is known, for example.

  Patent Document 1 discloses a processing tank that heats an organic substance that has been shut off from outside air, a magnetized air supply mechanism that is attached to the lower part of the processing tank and supplies magnetized air to the inside of the processing tank, and a magnetization of the magnetized air supply mechanism. An electromagnetic valve that adjusts the air supply amount, a temperature sensor that detects the temperature inside the processing tank, and a temperature sensor that detects that the temperature inside the processing tank has exceeded a certain temperature connected to the electromagnetic valve and temperature sensor. An organic substance processing apparatus is described that includes a controller configured to operate an electromagnetic valve so as to reduce the supply amount of magnetized air in the magnetized air supply mechanism.

  The organic matter processing apparatus according to Patent Document 1 automatically supplies magnetized air by the linkage of an electromagnetic valve, a temperature sensor, and a controller when the inside of the treatment tank becomes a suitable environment for thermally decomposing organic matter as seen from the temperature. The organic matter is prevented from becoming a high-temperature combustion state.

Further, a blower 35 for forcibly sucking and introducing outside air into the outside air inlet 34 is provided near the combustion chamber 31.

  As shown in detail in FIGS. 3 and 6, the heat exchanger 4 separates and removes moisture contained in the gas G, is formed in a drum shape, and its axis is orthogonal to the axis of the combustion processing mechanism 3.

It is bent and projected in an L shape outside the tank 1. The magnet 52 is not limited with respect to the opposed magnetic poles. The magnetized air supply mechanism 5 does not include a supply power source, and magnetized air A is sucked into the processing tank 1 by the pressure difference between the inside and outside of the processing tank 1 due to the thermal decomposition of the organic matter P. It is like that.

  The electromagnetic valve 6 adjusts the supply amount of the magnetized air A from the magnetized air supply mechanism 5 to the inside of the processing tank 1. A flow rate adjusting valve type is adopted and the magnet 52 of the nozzle 51 of the magnetized air supply mechanism 5.

A discharge port 91 b connected to the nozzle is positioned near the installation height of the nozzle 51 of the magnetized air supply mechanism 5 and is directed toward the axial center of the processing tank 1. The blower 92 applies a forcing force to the gas G flowing inside the duct 91 from the upper side to the lower side.

  As shown in detail in FIG. 7, the hot water supply mechanism 10 includes a jacket-type heat exchange unit 101 provided on the side surface of the treatment tank 1 and a coil-type heat exchange unit 102 provided on the combustion treatment mechanism 3. A circulation circuit is connected to the hot water storage tank 104 by a water supply path 103. A pump 105, a check valve 106, an auxiliary tank 107, and an on-off valve 108 are connected to the water supply path 103 between the hot water storage tank 104 and the heat exchange unit 102 provided in the combustion processing mechanism 3. A path that flows from the provided heat exchanging unit 102 toward the heat exchanging unit 101 provided in the processing tank 1 is configured.

  The hot water supply mechanism 10 is connected to an existing hot water supply facility 20 via a pump 109 and a check valve 1010. The existing hot water supply mechanism 20 includes a water supply tank 201 that stores raw water W such as tap water, a boiler 202 that heats the raw water W, and a hot water storage tank 203 that stores hot water that is the heated raw water W. The hot water storage tank 203 of the existing hot water supply mechanism 20 is connected to the hot water supply line by a circulation circuit, and is connected to the hot water supply mechanism 10 so that hot water can be supplementarily received from the hot water storage tank 104 of the hot water supply mechanism 10. Yes. The hot water storage tank 104 of the hot water supply mechanism 10 is connected to the water supply tank 201 of the existing hot water supply mechanism 20 so as to be supplied with the raw water W.

  In order to operate this mode, the organic substance P is charged on the rooster 13 from the charging port 11 of the processing tank 1 and the heater 2 is energized.

  At this time, the electromagnetic valve 6 is opened by the controller 8 so that a large amount of the magnetized air A can be supplied from the magnetized air supply mechanism 5 to the inside of the processing tank 1.

  The organic matter P heated by the heater 2 is heated to water, ash (inorganic matter, carbon, etc.), gas (carbon dioxide, hydrocarbon, etc.) under the supply of magnetized air A from the nozzle 51 of the magnetized air supply mechanism 5. It will be disassembled.

  At this time, since the tip 51a of the nozzle 51 of the magnetized air supply mechanism 5 is a tapered end port facing downward, the rise of the magnetized air A is restricted and the organic matter accumulated in the rooster 13 of the treatment tank 1 It is reliably supplied to the inside of P. In addition, since the plurality of nozzles 51 of the magnetized air supply mechanism 5 are radially arranged in the cylindrical processing tank 1 and directed toward the axial center of the processing tank 1, the magnetized air A is directed to the organic matter P inside. It will be supplied evenly. Therefore, the thermal decomposition of the organic substance P proceeds reliably and efficiently.

  When the pyrolysis of the organic substance P proceeds and the temperature sensor 7 detects that the inside of the treatment tank 1 has exceeded a certain temperature, the controller 8 closes the electromagnetic valve 6 or throttles the opening. Thus, the supply amount of the magnetized air A from the magnetized air supply mechanism 5 to the inside of the processing tank 1 is decreased.

  As a result, the inside of the treatment tank 1 does not have excess oxygen and the organic matter P is not in a combustion state, and the above-described thermal decomposition of the organic matter P is reliably continued.

  In addition, as the temperature inside the processing tank 1 for reducing the supply amount of the magnetized air A, the temperature of the gas G detected by the upper temperature sensor 71 of the temperature sensor 7 is 180 to 230 ° C., and the lower temperature sensor 72 of the temperature sensor 7. The temperature of the organic substance P detected by is suitably 300 to 500 ° C. However, with regard to these temperatures, when the organic substance P is additionally charged at the initial stage of operation, the temperature of the organic substance P increases even if the temperature of the gas G is low, or ash is increased due to decomposition of the organic substance P. In some cases, even if the temperature of the organic substance P is low, the temperature of the gas G may be high. Therefore, the control of the electromagnetic valve 6 of the controller 8 based on the detected temperatures of the upper temperature sensor 71 and the lower temperature sensor 72 of the temperature sensor 7 needs to be programmed in detail so as to cope with the progress of thermal decomposition.

  The gas G generated by the thermal decomposition of the organic matter P rises inside the processing tank 1, and a part thereof is discharged to the combustion processing mechanism 3 through the heat exchanger 4, and the remaining part flows to the gas flow mechanism 9. The

  At this time, since the suction port 91a of the duct 91 of the gas flow mechanism 9 protrudes into the processing tank 1, a part of the rising gas G can be reliably collected in the gas flow mechanism 9.

  The gas G flowing through the gas flow mechanism 9 is discharged from the discharge port 91b of the duct 91 so as to be blown into the organic matter P accumulated in the rooster 13 of the processing tank 1.

  At this time, since the discharge port 91b of the duct 91 of the gas flow mechanism 9 is positioned near the installation height of the nozzle 51 of the magnetized air supply mechanism 5 and is directed toward the axial center of the processing tank 1, the discharge is performed from the discharge port 91b. The gas G is urged by the magnetized air A supplied from the nozzle 51 and directed toward the axial center of the processing tank 1.

  As a result, convection of the gas G is formed in the processing tank 1, and the temperature inside the processing tank 1 is equalized. Accordingly, the temperature inside the processing tank 1 is accurately grasped by the temperature sensor 7, and the timing for operating the electromagnetic valve 6 is accurate. That is, an environment suitable for thermally decomposing the organic substance P can be reliably realized.

  In addition, the gas G (180-230 degreeC) which rose to the heat exchanger 4 is cooled inside the main-body part 41, and the water | moisture content (water vapor | steam) contained in the gas G is liquefied. The water separated and removed from the gas G by liquefaction is returned to the inside of the processing tank 1 from the drain pipe 43 of the heat exchanger 4.

  The gas G dried by the heat exchanger 4 rises to the combustion processing mechanism 5.

  The gas G that has risen to the combustion processing mechanism 3 is heated to a temperature of 1000 ° C. or more by the heat generating catalyst material 33 and is subjected to combustion processing to be detoxified and non-brominated. Note that heat generation of the catalyst material 33 of the combustion processing mechanism 3 is prevented from leaking to the outside by the refractory material 32. Therefore, no fuel is required for the combustion treatment of the gas G, and the operation cost is reduced.

  In the combustion process of the gas G in the combustion processing mechanism 3, oxygen as an auxiliary agent is positively supplied by the outside air inlet 34 and the blower 35. Accordingly, a reliable combustion process is performed in synergy with the fact that the gas G to be subjected to the combustion process is dried in the heat exchanger 4. In addition, as a catalyst material 33 of the combustion processing mechanism 3, aluminum oxide and silicon dioxide are added as a catalyst for assisting heat generation to silicon carbide, which is a heat generating material as a main component, so that the combustion processing under high heat is performed. Is surely done.

  Since the catalyst material 33 of the combustion processing mechanism 3 is porous and the outside air is supplied from the outside air inlet 34 and the blower 35, the gas G is ensured to rise in the catalyst material 33.

  Furthermore, when the organic matter P is processed, hot water supply that effectively uses the heat generated by the processing hot water supply mechanism 10 is performed. In this hot water supply, the raw water W is efficiently heated by supplying water from the combustion treatment mechanism 3 side that is relatively hot in the combustion process to the treatment tank 1 side that is relatively low in temperature. The hot water supply mechanism 10 is suitable for supplying a constant temperature and amount of hot water continuously for a long time. Therefore, by connecting the hot water supply mechanism 10 to the existing hot water supply equipment 20, the hot water supply mechanism 10 is responsible for auxiliary hot water supply to the existing hot water supply equipment 20 that performs full-scale hot water supply when the amount of hot water used is large. When the amount of hot water used is small, the existing hot water supply facility 20 can be stopped and the hot water supply mechanism 10 can carry out full-scale hot water supply. As a result, the heat energy of the hot water supply can be reduced by utilizing the heat of the treatment of the organic matter P that is waste.

  As described above, in addition to the illustrated form, it is possible to adopt a side loading type in which the organic substance P is charged from the side.

  Further, a plurality of gas flow mechanisms 9 can be provided.

  Further, the blower 35 of the combustion processing mechanism 3 is also connected between the upper door and the lower door of the processing tank 1, and when the organic substance P is additionally charged, the upper door of the processing tank 1. The gas G leaked between the lower doors can be sucked and purged.
