Japanese Patent Laid-Open No. 2006-97322 Japanese Patent No. 5177770

  The invention described in Patent Document 1 has a problem that the waste is treated by the reaction between the organic waste and steam, but the untreated portion of the organic waste remains in part. In addition, paragraph [0137] of Patent Document 1 only describes that the steam after treatment is extracted from the saturated steam exhaust pipe, and therefore organic waste that generates harmful substances such as chlorine compounds when exhausted in the steam state. There was a problem that things could not be processed.

  The invention described in Patent Document 2 has a problem that the processing apparatus becomes large because the container is a horizontally long cylindrical type. Further, paragraph [0057] of Patent Document 2 describes that the air in the container is discharged to the outside through the vent pipe and the intake pipe, and the problem that organic waste that generates harmful substances such as chlorine compounds cannot be treated. was there.

  Furthermore, in the case of a cylindrical processing container, when taking out the residue remaining in the processing container, there is a problem that it takes time to apply pressure to the residue discharge port in one place, but a stirring blade is attached. Since the rotating shaft is long, there is a problem that it is easily bent by the stirring operation, and there is also a problem that the tip end portion of the stirring blade comes into contact with the inner peripheral wall of the cylindrical processing container due to the bent rotating shaft and the inner peripheral wall is scratched.

  Therefore, the inventor of the present application treats the reaction between the organic waste and the steam by carbonization and activation by an oxidation reaction with the steam, so it is important to permeate the steam into the organic waste. For this reason, if drain is attached around the organic waste, the vapor does not penetrate into the organic waste from the part where the drain is attached. The present invention has been conceived by creating an unattached state.

  The present invention has been devised in view of these problems, and drains generated by the reaction are not attached to the periphery of organic waste, and vapor containing harmful substances such as chlorine compounds can be recovered in liquid form. It is an object of the present invention to provide an organic waste treatment apparatus and an organic waste treatment method.

The organic waste treatment process, and drain discharged from the organic waste treatment process in the drain storage tank maintained at the same pressure as the pressure in the reaction tank at least in parallel with the organic waste treatment process. Drainage And a cooling step for cooling and liquefying the steam flowing out from the organic waste treatment step by flowing into the cooling water bath when the inside of the reaction vessel is depressurized after the organic waste treatment step. It is characterized by that.

  The organic waste treatment apparatus according to claim 1 can be safely recovered by changing into a liquid even if vapor containing harmful substances such as chlorine compounds is generated by the treatment of the organic waste.

  In addition, drain that increases due to reaction with high-temperature and high-pressure steam in the reaction tank can be discharged to the drain storage tank during the reaction with high-temperature and high-pressure steam, so that even if drain is generated in the reaction tank, Since it flows out into the tank, it is possible to create a state in which almost no drain exists in the reaction tank. As a result, there is an effect that the high-temperature high-pressure steam penetrates into the organic waste during stirring and the reaction is promoted, so that no unreacted portion of the organic waste is generated.

The organic waste treatment apparatus according to claim 1 , wherein steam injected from a steam injection pipe on the peripheral wall of the cylindrical residue extraction portion provided in the opening at the bottom of the reaction tank is provided in the residue extraction portion. By disposing the steam injection pipe so as to be injected from the peripheral wall toward the opposing peripheral wall and to be injected obliquely upward from the peripheral wall of the residue take-out part toward the central part of the reaction tank, By spraying high-temperature and high-pressure steam from a steam spray pipe, it is possible to prevent drains and residues from being present in the residue take-out portion, and the organic waste in the reaction vessel is jetted toward the central portion of the reaction vessel. Since the high-temperature and high-pressure steam is put into a fluid state and the drain attached to the organic waste is also blown away, the steam is easily penetrated into the organic waste, so that the reaction is promoted and the unreacted portion of the organic waste is reduced. It does not occur Achieve the results.

  The organic waste processing apparatus 1 of the present invention carbonizes and activates organic waste from food factories, general households, supermarkets, and other stores by oxidation reaction with high-temperature and high-pressure steam.

  As shown in FIG. 1 or 2, an organic waste treatment apparatus 1 according to the present invention is an organic waste treatment apparatus 1 for treating organic waste, and includes steam generation means 2 for generating high-temperature and high-pressure steam, Injecting the organic waste provided in the upper part, the residue extracting part 4 for taking out the organic waste residue provided in the bottom, the residue extracting part 4 and the high-temperature and high-pressure steam provided in the upper part are jetted A steam tank 11 to 16 and a reaction tank 5 equipped with a stirring means 8 for stirring the organic waste charged therein, connected to the reaction tank 5 by the first pipe 21, and discharged from the reaction tank 5. The first piping 21 for flowing the generated steam is immersed in water and connected to the cooling water tank 6 for liquefying the steam by the steam generating means 2 and the first piping 22 as shown in FIG. As shown, the upper part of the reaction tank 5 is connected to the fourth pipe 24. To fluidly the steam, and is provided with a drain reservoir 7 which is flowable drain connected near the bottom and the third pipe 23 of the reactor 5.

  The steam generating means 2 may be any means that can generate steam having temperature and pressure so as to be carbonized and activated by oxidation reaction of organic waste with steam, for example, a kerosene boiler for boiling water. And as an example of the temperature and pressure of a vapor | steam, a 1-2MPa vapor | steam may be supplied at 220-230 degreeC, for example. The high-temperature and high-pressure steam generated by the steam generating means 2 is supplied to the reaction tank 5 through a steam supply pipe 20. The steam supply pipe 20 is provided with a thermometer (not shown) and a pressure gauge (not shown), and a check valve (not shown) and a pressure regulator 35 are provided and supplied to the reaction tank 5. The temperature and pressure of the high-temperature and high-pressure steam are controlled by a control unit (not shown). Since the supply time of the high-temperature and high-pressure steam can be controlled by the control unit, the temperature, pressure and supply time of the high-temperature and high-pressure steam are optimal for carbonization and activation by the oxidation reaction with steam for organic waste. Can be set and maintained. In addition, a safety valve (not shown) is provided in the kerosene boiler of the steam generating means 2 such as a kerosene boiler so as not to cause abnormal pressure.

  The reaction tank 5 includes an input unit 3 for introducing organic waste provided in an upper opening, a residue extraction unit 4 for extracting organic waste residues provided in a bottom opening, the residue extraction unit 4 and Vapor injection pipes 11 to 16 for injecting the steam provided in the upper part, a stirring means 8 for stirring the input organic waste, and a steam outlet 31 for taking out the high-temperature and high-pressure steam in the reaction tank 5 are provided.

  The throwing unit 3 is a part for feeding organic waste into the reaction tank 5. After throwing the organic waste, an opening / closing valve (not shown) such as a ball valve is operated to Seal the opening.

  The vapor injection pipes 11 to 16 are disposed at least in the upper part of the reaction tank 5 and the residue extraction part 4. The high-temperature and high-pressure steam sprayed from the steam spray pipes 11 and 12 disposed in the upper part of the reaction tank 5 penetrates into the organic waste and is disposed in the residue take-out section 4 as shown in FIG. The high-temperature and high-pressure steam sprayed from the steam spray pipes 13 to 16 blows back the drain and the organic waste falling to the residue extraction unit 4 from the residue extraction unit 4 into the reaction tank 5. The attachment position and number of the steam injection pipes are not limited to the positions and numbers, and are appropriately set depending on the size and form of the reaction tank 5.

  As shown in FIG. 4 (a), when the steam injection pipe 50 for injecting the high temperature and high pressure steam in the horizontal direction to the residue extraction portion 4 is in a single form, the high temperature and high pressure steam is opposed to the inner periphery of the residue extraction portion 4 facing the inner periphery. While colliding with the wall surface and reflecting inside the residue extraction portion 4 to reduce the momentum, as shown in FIG. 4B, high temperature and high pressure steam is horizontally applied to the residue extraction portion 4 of the present invention as shown in FIG. In the case of the form in which the high-temperature high-pressure steam is injected toward the inside of the vapor injection pipes 13 and 14 and the reaction tank 5 to be injected, the high-temperature high-pressure steam collides with each other from the opposite horizontal direction in the residue extraction portion 4 and reacts. It is injected directly into the tank 5.

  Thereby, when the reaction is completed and the inside of the reaction tank 5 is decompressed to open the ball valve 40 of the residue extraction section 4, the steam injection pipes 13 to 16 are disposed at four locations of the present invention. As shown in FIG. 5 (a), the residue in the cylindrical body of the residue take-out portion 4 was all discharged, and nothing was left cleanly, and all the organic waste that had been input was processed. On the other hand, as a comparative example, as shown in FIG. 5 (b), in the case where the high-temperature high-pressure steam is injected from only one place in the horizontal direction, a bridge made of residue or the like so as to cover the upper part of the cylindrical body of the residue extraction portion Phenomenon 70 was seen.

  As shown in FIGS. 3 (b) and 3 (c), the steam injection pipes 13 to 16 disposed in the residue take-out section 4 are arranged in a cylindrical shape provided at the bottom opening of the reaction tank 5. The steam ejected from the steam jet pipes 13 and 14 on the peripheral wall of the residue extracting section 4 is sprayed from the peripheral wall of the residue extracting section 4 toward the opposing peripheral wall, and the residue extracting section 4 Vapor injection pipes 15 and 16 are arranged so as to inject obliquely upward from the peripheral wall toward the center of the reaction vessel 5. As a result, no drain or organic waste is left in the residue extraction unit 4. In addition, since the organic waste in the reaction tank 5 is caused to flow obliquely upward toward the central portion of the reaction tank 5, the high-temperature and high-pressure steam easily penetrates into the organic waste. ing.

  The agitation unit 8 agitates the organic waste by rotating a plurality of blades attached to a rotary shaft 10 disposed at the center of the reaction vessel 5. The gap between the tip of the blade and the inner peripheral surface of the reaction vessel 5 is, for example, about 5 mm. If this gap is wide, organic waste that is not stirred is generated, and if this gap is too narrow, there is a concern that the tip of the blade comes into contact with the inner peripheral wall surface of the reaction tank 5. The size and form of the blades of the stirring means 8 may be any form that can be set so as to create a state in which high-temperature and high-pressure steam can enter the organic waste, with a gap of about 5 mm from the inner wall surface of the reaction tank 5.

  The residue extraction unit 4 is provided immediately below an opening provided at the bottom of the reaction vessel 5. It is a part for taking out the residue of organic waste after completion of the reaction, and has a cylindrical shape. During the reaction, an on-off valve such as a ball valve 40 provided at the lower part of the residue extraction unit 4 is operated to be in a sealed state, and upon completion of the reaction, an on-off valve such as a ball valve 40 provided at the lower part of the residue extraction unit 4 is used. To open. Further, steam injection pipes 13 and 14 for injecting steam in the horizontal direction and steam injection pipes 15 and 16 for injecting steam obliquely upward are disposed on the cylindrical peripheral wall of the residue extraction portion 4.

  The cooling water tank 6 is connected to the reaction tank 5 by a first pipe 21, and steam generated after the high-temperature high-pressure steam and organic waste react in the reaction tank 5 is connected to a steam outlet 31. After that, the pressure is adjusted by the pressure regulator 36 and is flown into the first pipe 21, the large solid is removed by the strainer 37, the sound is silenced by the silencer 38, sent to the cooling water tank 6, and immersed in the cooling water tank 6. The steam is liquefied as it flows in the first pipe 21. By liquefying, for example, harmful substances such as chlorine compounds can be collected in the liquid and collected in the container 39.

  The drain storage tank 7 is connected to the steam generating means 2 by the second pipe 22 or connected to the upper part of the reaction tank 5 by the fourth pipe 24 so that the steam can flow and is near the bottom of the reaction tank 5. And the third pipe 23 to allow the drain to flow. Further, if the installation height of the drain storage tank 7 is set lower than the height of the drain outlet 30 of the reaction tank 5, the drain in the reaction tank 5 flows out into the drain storage tank 7 by natural fall. Further, when the installation height of the drain storage tank 7 is made higher than the height of the drain outlet 30 of the reaction tank 5, the drain in the reaction tank 5 is pumped up and drained into the drain storage tank 7. Can be made.

  As a result, the pressure in the reaction tank 5 and the pressure in the drain storage tank 7 are made the same, and the drain generated by the reaction between the high-temperature and high-pressure steam and the organic waste is promptly stored in the reaction tank 5. The drain tank 7 is allowed to flow out into the drain storage tank 7 to create a state in which no drain exists in the reaction tank 5. For this reason, since it is difficult for the drain to adhere to the stirred organic waste, the high-temperature and high-pressure steam penetrates into the organic waste, so that there is no untreated portion of the organic waste and all the waste can be treated.

  The form of the reaction tank 5 is a spherical reaction tank 5 having a spherical shape. Compared with the same internal volume by using a spherical shape, for example, it can be made smaller than a cylindrical container, and the rotating shaft 10 can be made shorter than the cylindrical container, so that the stirring blade attached to the rotating shaft 10 is rotated. Thus, even when the organic waste is pushed forward and a large load is applied to the rotary shaft 10, it is possible to prevent the rotary shaft 10 from being bent, and shortening the rotary shaft 10 can prevent thermal deformation from increasing.

  Next, the usage method of the organic waste disposal apparatus 1 will be described. First, the optimum temperature, pressure and supply time of the high-temperature and high-pressure steam are selected and set according to the type and amount of organic waste to be introduced. Then, the on-off valve such as the ball valve of the charging unit 3 of the reaction tank 5 is opened, and the on-off valve such as the ball valve 40 of the residue extracting unit 4 is closed, and the organic waste is charged into the reaction tank 5. After completion of the charging, the on-off valve such as the ball valve of the charging unit 3 is closed to make the reaction vessel 5 sealed.

  Next, steam generation by the steam generating means 2 is started. As a result, high-temperature and high-pressure steam at the set temperature and pressure is supplied for the set supply time, the stirring blades of the stirring means 8 rotate, and the organic waste rotates in the reaction tank 5. High-temperature and high-pressure steam enters the organic waste and is carbonized and activated by an oxidation reaction with the steam.

  Water droplets that become drainage are generated by carbonization and activation in the oxidation reaction with the steam and start to accumulate at the bottom of the reaction vessel 5. At this time, the reaction tank 5 and the drain storage tank 7 are set to the same pressure, and if the height of the drain storage tank 7 is made lower than the height of the drain outlet 30 provided near the bottom of the reaction tank 5, As soon as the drain begins to accumulate, it immediately and naturally flows into the drain storage tank 7. Thereby, the state in which no drain exists in the reaction vessel 5 can be maintained.

  Further, the high-temperature and high-pressure steam is disposed in the residue take-out section 4, and the high-temperature and high-pressure steam is injected obliquely upward toward the two steam injection pipes 13 and 14 for injecting the high-temperature and high-pressure steam in the horizontal direction and the reaction tank 2. A total of four steam injection pipes 15 and 16 create a state in which no residue exists in the cylindrical shape of the residue extraction portion 4. Then, the organic waste is caused to flow into the reaction tank 5 by the high-temperature and high-pressure steam jetted obliquely upward toward the reaction tank 5. This flow facilitates the penetration of high-temperature and high-pressure steam into the organic waste.

  Since the drainage of the drain into the drain storage tank 7 and the injection of the high-temperature high-pressure steam from the residue take-out section 4 do not have any drain in the reaction tank 5 and the organic waste is stirred while flowing, the supply time of the high-temperature high-pressure steam Even if carbonization and activation progress by oxidation reaction with steam after the passage of time, drain does not easily adhere to organic waste, so high-temperature and high-pressure steam easily penetrates into organic waste, and carbonization and activation by oxidation reaction with steam Will continue to be promoted. Thereby, there is no untreated part of the organic waste, and the treatment of the organic waste can be completed.

  When the high-temperature high-pressure steam supply time has elapsed, the high-temperature high-pressure steam is caused to flow into the cooling water tank 6 in order to reduce the pressure in the reaction tank 5 to atmospheric pressure. Then, after the pressure in the reaction tank 5 is reduced to atmospheric pressure, an open / close valve such as the ball valve 40 of the residue extraction unit 4 is opened, and the residue in the reaction tank 5 is taken out by dropping.

  Next, the organic waste processing method 60 will be described. The organic waste processing method 60 is an organic waste processing method 60 for processing organic waste, which includes a steam generation step 61 for generating high-temperature and high-pressure steam, and the organic waste in the reaction tank 5. After charging and sealing the inside of the reaction tank 5, the steam generated in the steam generation step 61 is injected from the upper part of the reaction tank 5 and the peripheral wall of the cylindrical residue extraction part 4 provided at the lower part of the reaction tank 5 From the horizontal direction and obliquely upward, which is the central region direction of the reaction vessel 5, and while stirring the organic waste, carbonization and activation are performed by an oxidation reaction with steam, and organic Organic waste treatment step 62 for treating waste, and drain discharged from the organic waste treatment step 62 in the drain storage tank 7 maintained at the same pressure as the pressure in the reaction vessel 5 are at least organic. Waste treatment process 2 and the drain storage process 63 stored in parallel with the organic waste treatment process 62, the steam discharged from the organic waste treatment process 62 flows into the cooling water tank 6 when the pressure in the reaction tank 4 is reduced. And a cooling step 64 for cooling and liquefying.

  The injection of the high-temperature and high-pressure steam from the residue extraction unit 4 is performed so that two high-temperature and high-pressure vapors are injected from the peripheral wall of the residue extraction unit 4 toward the opposing peripheral wall, and the other two high-temperature and high-pressure vapors. Steam injection pipes 13 to 16 are arranged so that the steam is injected obliquely upward from the peripheral wall of the residue extraction portion 4 toward the central region of the reaction tank 5.

  In the drain storage step 63, the drain that has started to accumulate in the reaction tank 5 is quickly flowed to the drain storage tank 7 that can maintain the same pressure as the pressure in the reaction tank 5 of the organic waste treatment process 62. ing.

  Since the drainage of the drain into the drain storage tank 7 and the injection of the high-temperature high-pressure steam from the residue take-out section 4 do not have any drain in the reaction tank 5 and the organic waste is stirred while flowing, the supply time of the high-temperature high-pressure steam Even if carbonization and activation progress due to the oxidation reaction by steam after the passage of time, drain does not easily adhere to the organic waste, so high-temperature and high-pressure steam penetrates into the organic waste and the carbonization and activation deteriorates due to the oxidation reaction by the steam. Absent. Thus, the organic waste can be completed without any untreated portion.

  In the cooling step 64, the vapor flowing out from the waste treatment step 62 is cooled and liquefied, so that harmful substances such as chlorine compounds can be included in the liquid and recovered.
