Definitions
- organochlorine pesticides such as PCP (pentachlorophenol), chlordene, BHC (hexachlorocyclohexane), anoredrine, dieldrin, endrin, DDT, and PCNB are It is addictive to the human body, accumulates in the human body and adversely affects the liver, etc., and dioxins may be mixed in during the manufacturing process, so production, use and sales are now prohibited by law. Yes.
- One method for detoxifying such soil is to dig up agricultural chemicals from the soil and detoxify the digged agricultural chemicals by chemical treatment (see, for example, Patent Document 1).
- Patent Document 1 There is a fundamental problem that pesticides that have spread to the sea are not suitable.
- the excavated soil contains paper bags and bottle debris encapsulated with pesticides, and a process for removing these debris is necessary. In some cases, there were technical and cost problems.
- the first pipe having the first passage that can be filled with alkali can be inserted into and removed from the first hole of the processing chamber where POPs are thermally decomposed.
- the passage is configured to have a third region between the first region and the second region into which the soil that has been heat-treated under reduced pressure is introduced. Moyore. This soil functions as a reducing agent, and the soil in this area also functions as the conductance of piping. [0047] In the present invention, it is preferable that at least a part of the passage is provided in a room, and it is more preferable that the room is divided into regions.
- the processing apparatus of the present invention can realize the processing method of the present invention as described above. That is, the present invention is a processing apparatus capable of processing an object to be processed containing an organic halide, and includes a first hermetic region that can accommodate and heat the object to be processed, and the first airtight.
- An exhaust system capable of depressurizing the region, and a second region disposed between the first hermetic region and the exhaust system and capable of heating the fraction generated by heating the object to be treated. It is characterized by comprising an airtight region, a reaction chamber inserted between the second airtight region and the exhaust system and filled with solid alkali inside.
- the second hermetic zone not only neutralizes halogen, but also has the function of thermally decomposing dioxins and pesticides derived from the object to be treated. For example, there is a possibility that the agricultural chemicals evaporate and move the exhaust system until the predetermined processing temperature is reached after heating the object to be processed. By heating the second hermetic zone, it can also be used as an exhaust gas treatment device.
- the present invention is characterized in that, in the processing system, the condensing unit is connected to the second processing unit via at least a second valve that controls the flow of airflow. .
- Each of the above-described valves can be suitably inserted, for example, between the first pipe and / or the second pipe and the third passage.
- first part is, for example, soil produced by vacuum heating (first heat medium)
- second part is filled with alkali such as quicklime CaO (second heat medium). May be. It is not excluded to mix and fill the first part with vacuum-heated soil and alkali.
- the drive shaft 37 is connected to the screw 36 on the cantilever support end side in the first heat treatment furnace 28.
- the shaft 37 communicates with the inside and outside of the first heat treatment furnace 28 and has a dust-proof seal. It is connected with the shaft 39 held by 38, 48a, 48b and the unino-kusano join 40. As a result, the bearing 38 is prevented from being deteriorated in sealing performance due to external force.
- Through holes 49 and 50 communicating between the inside and the outside are provided at two locations on the upper upstream side in the first heat treatment furnace 28.
- These through-holes 49 and 50 each have a retort pipe that can be inserted and removed.
- the retort 85 is provided in the first heat treatment furnace 28 and the force is also provided on the upstream side thereof, so that the first heat treatment furnace 28, the second heat treatment furnace 29, and the cooling treatment on the downstream side are provided.
- the degree to which the furnace 30 is contaminated by the thermal decomposition components of the pesticide can be made relatively small. Further, since it is close to the cantilever support side, it is possible to prevent a vacuum leak in the vacuum heating device main body 16 in which the retort 85 is hardly displaced due to thermal expansion.
- halogens such as chlorine derived from organic halides can be neutralized and fixed as a salt.
- chlordane is known to decompose by releasing chlorine when it comes into contact with alkali. Therefore, even if chlordane reaches the alkaline reactor, it can be decomposed and desorbed chlorine.
- the frequency of alkali exchange in the alkali reactor 71 described later can be reduced. As a result, the vacuum heating device 3 can be operated continuously over a long period of time, and the throughput is improved.
- caps 86 are detachably attached to the upper ends of the U-shaped pipes 77, 78, 79, respectively. Remove this cap 86 from the pipes 77, 78, 79, and throw an annunciator 87 into the passages of the self pipes 77, 78, 79. It can be taken out.
- Each of the alkalis 87 is filled with a solid state alkali (for example, quicklime (CaO)).
- halogen such as chlorine derived from organic halides and fixation as a salt.
- the catalytic oxidation device 75 oxidizes the exhaust gas of the vacuum pump 73 with a catalyst. This is used for double safety (fail safe).
- the processing apparatus 1 shown in FIG. 1 has one purge chamber 17, whereas the processing apparatus 100 according to this embodiment is different in that purge chambers 101 and 102 are provided in two stages in series. .
- the downstream purge chamber is decompressed by the vacuum pump 73.
- the processing apparatus 1 shown in FIG. 1 has one purge chamber 18, whereas the processing apparatus 100 according to this embodiment differs in that purge chambers 103 and 104 are provided in two stages in series. .
- the processing apparatus 1 shown in Fig. 1 it was possible to perform continuous processing in batch units in the vacuum heating apparatus 3, but in the processing apparatus 100 according to this embodiment, the purge chambers 102 and 103 were used. The waiting time for purging is eliminated, the object to be processed can be processed almost continuously in the vacuum heating apparatus 3, and the throughput can be further increased.
- the caps 86 and 221 may be fixed with bolts and nuts to a flange that is not screwed.
