Description

  This invention is special management industrial waste processing such as waste asbestos discharged from discharge factory and scattering asbestos (sprayed asbestos) generated by asbestos removal construction with dismantling, repair work of building and vehicle The present invention also relates to a waste asbestos treatment apparatus and method which can be processed into a non-scattering asbestos exfoliation body with high safety on site and can be easily treated as general waste. Moreover, this invention relates to the asbestos solidification additive suitable for using for the processing apparatus and method of waste asbestos. In addition, the present invention is particularly suitable for solidified non-sprayed asbestos peeled bodies when the scattered asbestos peeled body and asbestos solidifying additive produced in the waste asbestos treatment apparatus and method are integrally solidified and processed into a non-scattering asbestos peeled body. The present invention relates to a stable fuel pellet manufacturing apparatus and method suitable for use in an embodiment that can be used as fuel pellets because the scatterable asbestos exfoliation body is high in calories. Furthermore, the present invention relates to a processing apparatus and method for waste asbestos encapsulated in a flexible container, which is suitable for use when it has already been treated by specially controlled industrial waste treatment.

  Conventionally, in the processing method of waste asbestos discharged from the removal process, asbestos removed at the site is first packed in a double plastic bag, loaded on a dedicated vehicle and transported to a managed final disposal site. Landfilled. In addition, waste asbestos and the like were cemented on site. However, solidification of cement such as waste asbestos leads to an increase in the amount of waste asbestos to be processed, which is inefficient in the work process, so when removing asbestos from the site of building demolition / renovation work, The person in charge hesitates to adopt, and the harmless treatment method as disclosed in Patent Document 1 is preferred.

  That is, when removing waste asbestos from a building demolition / renovation site, a detoxification processing device as disclosed in Patent Document 1, for example, has been proposed in order to increase the efficiency of the work process. (1) Take measures to prevent scattering of waste asbestos discharged from waste asbestos discharge factories. In addition, the waste from the building demolition / renovation site is directly packed in a double plastic bag and transported to an intermediate treatment plant. (2) In the intermediate treatment plant, the discharged material transported into the melting furnace in the melting facility is directly put together with the bag and melted and solidified at a furnace temperature of 1500 ° C. or higher. Asbestos fibers are melted and made harmless in the solidified waste asbestos “slag” and “carel”. (3) After melting and solidifying, detoxified slag, etc. can be buried in a stable final disposal site because it is a substance that falls under the scope of specially controlled industrial waste and falls under “glass scrap and ceramic scrap”.

JP-A-10-337547

  However, when the present inventor observed the construction situation and intensively studied, it was found that the above detoxification processing apparatus has room for further improvement. In other words, the waste from the building demolition / renovation work site is directly packed in a double plastic bag, but in the first place the scattering waste asbestos (sprayed asbestos) has a low specific gravity, so it is compressed and scattered waste asbestos ( Compared with the case where the sprayed asbestos is changed to a property corresponding to “glass waste and ceramic waste”, the volume is expanded about 100 times. Therefore, the volume of plastic bags filled with spillable waste asbestos also expands about 100 times, so even if it is loaded on one specially managed industrial waste dedicated vehicle and transported to an intermediate treatment plant, the transport cost is low. Increase.

  In addition, for those who are in charge of removing asbestos, considering the transportation costs using specially managed industrial waste vehicles and the detoxification costs at intermediate treatment plants, they are transported directly to a final disposal site that is managed and landfilled. Since the processing is not completely inferior as simple and quick processing, it is performed at a constant rate. Then, compared with the case where waste asbestos (sprayed asbestos) is compressed and changed to a property equivalent to “glass scraps and ceramic scraps”, the volume is about 100 times larger in a managed final disposal site. Long-term storage for about ten years will be performed. However, from the standpoint of a management-type final disposal site manager, it is necessary to occupy and manage plastic bags filled with spilled waste asbestos for a long period of time, and the waste asbestos remains stable even after several decades. Since it is a substance, its risk of carcinogenicity does not change, so there are many requests for detoxification treatment.

  According to the waste asbestos treatment apparatus and method of the present invention, a scattering asbestos peeling body generated at a building demolition site or a repair work site is processed into a non-scattering asbestos peeling body using an asbestos-solidifying additive at the site. It is possible to easily carry out the work of transporting the non-scattering asbestos exfoliation body to the final disposal site or the intermediate disposal site. In addition, the transport unit, asbestos-solidifying additive storage unit, and the stable conversion unit used in the waste asbestos processing apparatus of the present invention can be moved to a building demolition site or a repair work site in a state of being loaded on a truck.

  According to the processing apparatus for waste asbestos encapsulated in the flexible container of the present invention, the flexible container that has been landfilled is carried out or dug out and put into the stable conversion unit. In the stable type conversion unit, the scattering asbestos peeled body enclosed in a flexible container and the asbestos solidifying additive contained in the asbestos solidifying additive containing unit are solidified and processed into a non-scattering asbestos peeled body. However, it can be processed from specially controlled industrial waste to stable industrial waste so that it can be easily managed as general waste. In addition, the asbestos-solidifying additive storage unit, stable conversion unit, and removal filter can be moved to a managed final disposal site in a state of being loaded on a truck. Also gets higher.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a block diagram illustrating a waste asbestos treatment apparatus according to the present invention. In the figure, spraying asbestos 4 is sprayed on the wall surface and ceiling surface of a boiler room or the like of a building 2 in order to improve heat insulation and fire resistance. The repair worker 6 takes charge of the work of peeling the sprayed asbestos 4 from the wall surface at the repair work site of the building 2. The anti-scattering sheet 8 is used to isolate the asbestos 4 peeling work area from the surrounding environment. For example, a plastic sheet having a thickness of about 2 to 3 mm is used. The scattering asbestos peel-off body 10 is generated in an area surrounded by the scattering prevention sheet 8, and a dust-proof measure is taken so that the repair worker 6 does not inhale. Dust proofing measures are necessary to maintain the occupational health environment. From the viewpoint of preventing so-called mesothelioma, the asbestos-peeling body 10 is removed from the work environment by performing a wet treatment of asbestos 4 before the peeling operation. Prevent splashing inside. The specific contents of the dust-proofing measures include applying a paste-like substance for wet treatment to the sprayed asbestos 4 or spraying a pretreatment agent called a primer. The inside of the work environment surrounded by the scattering prevention sheet 8 is maintained in a negative pressure state to prevent the scattering asbestos peeler 10 from leaking to the surroundings. Therefore, in the room surrounded by the scattering prevention sheet 8, the scattering asbestos peeling body 10 exists in two types: a wet lump-like scattering asbestos peeling body 10a and a scattering asbestos peeling body 10b floating in the air. To do.

  The conveyance hose 12 connects the work area surrounded by the scattering prevention sheet 8 and the conveyance unit 20 and has airtightness so that the scatterable asbestos peeled body 10 does not leak into the environment. The crusher 14 is used for pretreatment when the scatterable asbestos peeler 10 is wet-processed, because the scatterable asbestos peeler is a large wet lump 10a. The crusher 14 arranges the wet-processed scattered asbestos exfoliation body 10a to an appropriate size and forms it into an air-carryable shape so that it can be conveyed by the conveyance hose 12, and has a pellet molding function, for example. It is good to have. Further, instead of the transport hose 12, it may be transported by conveyor. In this case, in order to prevent the floating dispersible asbestos peeler 10b from scattering, the entire conveying conveyor is isolated from the surroundings, and the entire conveying conveyor is surrounded by the scattering preventing sheet 8. Also keep negative pressure.

  The waste asbestos treatment device is composed of a transport unit 20, an asbestos-solidifying additive storage unit 30, and a stable conversion unit 40, and is moved to a building demolition site or a renovation site while being loaded on a truck 60. it can. Therefore, the scattered asbestos peeled body 10 generated at the building demolition site or the repair work site can be processed into a non-scattering asbestos peeled body at the site. The work to transport to the intermediate disposal site can be done easily.

  Here, the transport unit 20 includes a collection filter 22 that collects the scatterable asbestos peeler 10, an exhaust filter 24 that performs filtration so that the air discharged into the environment does not include the scatterable asbestos peeler 10, and a transport hose. 12, a transport pump 26 for transporting air containing the scatterable asbestos peeler 10 to the transport unit 20, and a transport pipe 28 for transporting the scatterable asbestos peeler 10 collected by the collection filter 22 to the stable conversion unit 40. Have. For the collection filter 22, for example, a filtration type dust collector (bag filter) is used. The bag filter has a structure in which a large number of filter cloths are incorporated in a steel box, and includes a main body, a filter cloth, a wiping device, an ash extraction conveyor, and the like. The filter cloth is obtained by processing glass fiber or the like into a cylindrical shape, which is like a paper pack of a vacuum cleaner. The flue gas entering from the inlet duct is collected on the surface of the filter cloth by the scattered asbestos exfoliation body 10 contained therein, and then comes out of the outlet duct. The scatterable asbestos exfoliation body 10 deposited on the filter cloth is wiped off by the high-pressure air blown from the injector pipe at regular intervals. The scattered asbestos peeled body 10 that has been wiped out is extracted to the outside by a conveyor and sent to the processing facility for the scattered asbestos peeled body 10.

As the exhaust filter 24, for example, a HEPA filter is used. HEPA filter is High
Abbreviation for Efficiency Particulate Air Filter. It is a filter that collects fine particles contained in air or exhaust gas with high performance, and is used in exhaust facilities such as nuclear facilities. In general, this means that dioctal phthalate (DOP, etc.) particles with a particle size of 0.15μm are collected with an efficiency of 99.97% or more with respect to the rated air volume. For example, in a nuclear facility, air in a management area is ventilated, and the air after ventilation is discharged from the exhaust facility as a gaseous waste, and a HEPA filter is used to remove radioactive particulates in the exhaust.

  The asbestos-solidifying additive storage unit 30 stores asbestos-solidifying additive 32. Here, asbestos-solidifying additive 32 may be, for example, fine-particle shaped or pulverized plastic 34. The plastics 34 in the form of fine particles or pulverized are used for recycling under the effective resource utilization promotion method. For the asbestos-solidifying additive storage unit 30, for example, a handler (not shown) or an air transporter is used for transport. For the handler (not shown), for example, a robot arm is used, and the plastic waste of the asbestos-solidifying additive storage unit 30 is gripped by the grip portion at the tip, and rotated from the asbestos-solidifying additive storage unit 30 to the funnel port 41. Then, the plastic waste is gripped by the gripping portion, dropped into the funnel port 41, and rotated again from the funnel port 41 to the asbestos-solidifying additive containing unit 30.

  The stable conversion unit 40 integrally separates the scatterable asbestos peeler 10 transported by the transport unit 20 and the asbestos-solidifying additive 32 accommodated in the asbestos-solidifying additive-accommodating unit 30 into a non-scattering asbestos detachment. The stable conversion unit 40 is preferably a volume reduction machine 45 that is molded into a pellet-like non-scattering asbestos peeled body. The volume reduction processing machine 45 integrally solidifies the scatterable asbestos peeled body 10 conveyed by the conveying unit 20 and the fine-particle-shaped or pulverized plastic 34 to process it into a non-scatterable asbestos peeled body. Is softened at a relatively low temperature of about 150 ° C. to 200 ° C., and this softening temperature is further lowered in a pressurized state, so that the scatterable asbestos peelable body 10 can be processed into a non-scatterable asbestos peelable body. In the volume reduction processor 45, for example, it is molded into a pellet-like solid material such as RDF or RPF. Therefore, in order to ensure the prevention of asbestos scattering around the pellet-like solid matter, a paste-like adhesive substance may be covered, and a pellet coating unit 48 for covering the periphery with a plastic film is installed. Also good.

Here, RDF is an abbreviation for Refuse Derived Fuel, and in Japanese it is called solid waste fuel. Combustible waste such as raw garbage, waste plastic, and waste paper is crushed and dried, then mixed with quick lime, and compressed and solidified. Since it is dried, compressed, and formed, it can be transported and stored for a long time, and used as a heat source. It can be mixed with coal and used for cement firing. The calorific value is about 5000kcal / kg, close to coal. Under the current law system, since the raw material is waste, the production of RDF is regarded as one of the intermediate treatment methods for general waste, and the municipalities are incinerated by the main business. Treatment facilities that incinerate RDF are required to take measures to reduce the emission of air pollutants, including dioxins, and to prevent dust scattering, waste gas treatment, and dioxin concentration measurement. Waste heat is used for electricity and steam. RPF is Refuse Paper &
Abbreviation for Plastic Fuel, it is a solid fuel with a constant shape and high density, so it has the same convenience as coke, pulverized coal, etc., and is excellent in handling, transportation and storage. And since the industrial waste whose generation | occurrence | production history is clear is used as a raw material, it has the property that stable quality is obtained compared with RDF.

The funnel port 41 is provided at the entrance of the fixed dose feeder 42, and the plastic 34 is charged therein. The fixed amount feeder 42 conveys a predetermined amount of the plastic waste that has been input to the funnel-type supply port 43. For conveyance, for example, a blower suitable for powder transportation may be used. In the case where the plastic 34 in the form of fine particles or ground is PET (polyethylene terephthalate) or nylon, a limestone feeder (not shown) is used to put limestone (calcium carbonate: CaCO ₃ ) into the funnel port 41. It is good to provide.

When plastic waste is used as the plastic 34, when the plastic waste is polyethylene terephthalate or nylon, it does not appear to contain chlorine. However, when recovered as plastic waste, the fact is that other transparent plastics containing chlorine are mixed. Therefore, calcium contained in limestone combines with chlorine gas that separates as the plastic waste is thermally decomposed to form calcium chloride. Calcium carbonate is theoretically composed of 56% calcium oxide (CaO) and 44% carbon dioxide (CO ₂ ), but limestone contains some impurities such as magnesium, alumina, silicic acid and iron. Yes.

  In the funnel-type supply port 43, the plastic 34 or a mixture of the plastic 34 and limestone is sent to the input port 44 of the volume reduction processor 45. The volume reduction processing machine 45, such as an RDF forming machine, is preferably one that solidifies the pulverized plastic waste again into a pellet, and the plastic waste is softened so that it can be easily molded as required. For example, it is preferable to raise the temperature to about 80 ° C. to 100 ° C., for example. The plastic waste solidified into pellets by the volume reduction processor 45 is sent to the stable waste holding tank 47 through the transport pipeline 46. When the pellet coating unit 48 is provided, the plastic waste that has been solidified into pellets by the volume reduction processing unit 45 is covered with a paste-like adhesive substance, or the periphery is covered with a plastic film, and the stable type It is sent to the waste holding tank 47. Here, processing the scattering asbestos peeling body 10 into a non-scattering asbestos peeling body means that it is handled as non-scattering asbestos waste, and also means having a property as a stable waste. The scattering asbestos exfoliation body 10 has a notification from the Ministry of the Environment as a legal treatment concerning waste disposal and cleaning (for example, ring waste production issue No. 050330010, issued on March 30, 2005, ring waste production occurrence) No. 0508220001, promulgated on August 22, 2005), it is necessary to comply with this administrative interpretation.

  The operation of the apparatus configured as described above will be described. FIG. 2 is a flowchart illustrating the method for treating waste asbestos according to the present invention. First, the truck 60 loaded with the waste asbestos treatment device is placed on the construction site (S102). And the repair worker 6 surrounds the wall surface which peels the scattering asbestos (spraying asbestos 4) of a construction site (building 2) with the scattering prevention sheet 8 (S104). At this time, the sprayed asbestos 4 is wetted to prevent the asbestos peeler 10 generated by the peeling work in the working environment from being released in a large amount in the atmosphere. Then, the repair worker 6 connects the peeling work site (building 2) and the transport unit 20 with the transport hose 12 via the scattering prevention sheet 8 (S106). Subsequently, the repair worker 6 confirms the storage state of the asbestos-solidifying additive 32 in the asbestos-solidifying additive storage unit 30 (S108), and if the amount required for this work is not stored, the asbestos-solidifying additive 32 is stored. Refill with solidification additive 32. In this way, the preparation stage of the waste asbestos treatment operation is completed.

  Then, the repair worker 6 peels off the asbestos-containing body (sprayed asbestos 4) on the wall surface and ceiling surface of the construction site (building 2) (S110). When the asbestos exfoliation body 10 when peeled becomes a large shape by wet processing and is not suitable for pneumatic transportation or powder transportation, the asbestos exfoliation body 10 is finely crushed to a particle diameter of several mm to several cm by a crusher 14 or Mold and arrange in an appropriate shape suitable for pneumatic transportation and powder transportation. And the asbestos peeling body 10 produced | generated by peeling operation | movement is conveyed by the conveyance unit 20 via the conveyance hose 12, or is conveyed by the conveyance conveyor to the conveyance unit 20 (S112). And the asbestos peeling body 10 and the asbestos solidification additive 32 conveyed by the conveyance unit 20 are integrally solidified by the stable conversion unit 40 and processed into a non-scattering asbestos peeling body (S114). At this time, by using the pellet coating unit 48 or the like, the plastic waste solidified into pellets by the volume reduction processor 45 is covered with a paste-like adhesive substance, or the periphery is covered with a plastic film. It is better to send it to the stable waste holding tank 47. The processed non-scattering asbestos exfoliation body can be reused as fuel in the form of pellets, and is treated as general waste as stable waste (S116).

  Then, the repair worker 6 determines whether or not the peeling work of the asbestos-containing body (sprayed asbestos 4) on the wall surface and ceiling surface of the construction site (building 2) has been completed (S118). And if peeling work is incomplete, it will return to S110 and will continue the peeling work of asbestos containing body (spraying asbestos 4). When the peeling work is completed, the repair worker 6 removes the transport hose 12 that connects the peeling work site 2 and the transport unit 20 (S120), and removes the scattering prevention sheet 8 from the construction site 2 (S122). The dust-proof clothing on which the removed anti-scattering sheet 8 and the repair worker 6 are worn is molded into a pellet-like solid material such as RDF or RPF at the site using the volume reduction processor 45. Therefore, the dust-proof clothing on which the removed anti-scattering sheet 8 or the repair worker 6 that has been conventionally treated as a content of scatterable asbestos is treated as a stable waste. Then, the person in charge of the waste asbestos treatment apparatus moves the truck 60 loaded with the waste asbestos treatment apparatus from the construction site 2 to the next site (S124).

  In addition, the non-scattering asbestos exfoliation body produced by the waste asbestos treatment method of the present invention is treated not only as a general waste, but also the non-scattering asbestos exfoliation body produced as a stable fuel pellet and positively. Can also be evaluated. In this case, the waste asbestos processing apparatus of the present invention shown in FIG. 1 is read as follows in the stable fuel pellet manufacturing apparatus. First, the conveyance unit 20 conveys the scattering asbestos peeling body 10, and is the same as that of the processing apparatus of waste asbestos. Next, the asbestos-solidifying additive storage unit 30 stores fine-particle shaped or pulverized plastic 34 (hereinafter referred to as “particulated plastic”). Asbestos-solidifying additive 32 is compared with a waste asbestos treatment apparatus. It is limited to fine particle shape or pulverized plastic 34 with high thermal energy. The volume reduction processing unit 40 solidifies and solidifies the scatterable asbestos peeled body 10 conveyed by the conveyance unit 20 and the plastic 34 accommodated in the asbestos-solidifying additive-accommodating unit 30 into pellets for stable fuel. However, as compared with the waste asbestos processing apparatus, the stable conversion unit 40 is limited to the volume reduction processing unit 40 including the volume reduction processing machine 45 adapted to the plastic 34.

  FIG. 3 is a flowchart illustrating a method of using the stable fuel pellet manufacturing apparatus of the present invention. First, the truck 60 loaded with the stable fuel pellet manufacturing apparatus is mounted on the construction site (S202). And the repair worker 6 surrounds the wall surface which peels off the scattering asbestos (spraying asbestos 4) of a construction site (building 2) with the scattering prevention sheet 8 (S204). At this time, the sprayed asbestos 4 is wetted to prevent the asbestos peeler 10 generated by the peeling work in the working environment from being released in a large amount in the atmosphere. Then, the repair worker 6 connects the peeling work site (building 2) and the transport unit 20 with the transport hose 12 via the scattering prevention sheet 8 (S206). Subsequently, the repair worker 6 confirms the accommodation state of the particulate plastic 34 in the asbestos-solidifying additive accommodation unit 30 (S208), and if the amount required for the current work is not accommodated, it is converted into particles. Refill with plastic 34. In this way, the preparatory work for the stable fuel pellet manufacturing apparatus that also serves as a waste asbestos treatment work is completed.

  Then, the repair worker 6 removes the asbestos-containing body (sprayed asbestos 4) on the wall surface and ceiling surface of the construction site (building 2) (S210). When the asbestos exfoliation body 10 when peeled becomes a large shape due to the wet treatment and is not suitable for pneumatic transportation or powder transportation, the crusher 14 prepares an appropriate shape suitable for pneumatic transportation or powder transportation. And the asbestos peeling body 10 produced | generated by peeling work is conveyed by the conveyance unit 20 via the conveyance hose 12, or is conveyed by the conveyance conveyor to the conveyance unit 20 (S212). And the asbestos exfoliation body 10 and the particulate plastic 34 which are conveyed by the conveyance unit 20 are integrally solidified by the volume reduction processing unit 40 and processed into stable fuel pellets (S214). Since the particulate plastic 34 is softened at about 80 ° C. to 120 ° C., it is easily integrated with the asbestos exfoliation body 10 by the volume reduction processing unit 40 and then solidified into a pellet by natural cooling. At this time, by using the pellet coating unit 48 or the like, the plastic waste solidified into pellets by the volume reduction processor 45 is covered with a paste-like adhesive substance, or the periphery is covered with a plastic film. It is better to send it to the stable waste holding tank 47. And the processed non-scattering asbestos exfoliation body can be reused as a fuel in a pellet state (S216).

  Then, the repair worker 6 determines whether or not the peeling work of the asbestos-containing body (sprayed asbestos 4) on the wall surface and ceiling surface of the construction site (building 2) has been completed (S218). And if peeling work is incomplete, it will return to S210 and will continue peeling work of asbestos containing body (spraying asbestos 4). When the peeling work is completed, the repair worker 6 removes the transport hose 12 that connects the peeling work site 2 and the transport unit 20 (S220), and removes the scattering prevention sheet 8 from the construction site 2 (S222). The dust-proof clothing on which the removed anti-scattering sheet 8 and the repair worker 6 are worn is molded into a pellet-like solid material such as RDF or RPF at the site using the volume reduction processor 45. Therefore, the dust-proof clothing on which the removed anti-scattering sheet 8 or the repair worker 6 that has been conventionally treated as a content of scatterable asbestos is often made of plastic such as polyethylene and has high calorie. Therefore, it is suitable for reuse as fuel. The person in charge of the stable fuel pellet manufacturing apparatus moves the truck 60 loaded with the stable fuel pellet manufacturing apparatus from the construction site 2 to the next site (S224).

  FIG. 4 shows a case where the waste asbestos treatment apparatus of the present invention is used when a scattered asbestos exfoliated material already managed as a specially managed industrial waste at a managed final disposal site is processed into a stable industrial waste. FIG. In the figure, in the management-type final disposal site 70, it is considered that the waste that has been landfilled is not leaked to the surrounding environment by surrounding it with the retaining wall 72, etc. A display board 74 to that effect is provided. The individual scattering asbestos exfoliation body is sealed in a flexible container 76 such as plastic.

  A worker 78 of the waste asbestos processing apparatus moves to a management-type final disposal site on a truck 60 loaded with a transport unit 20, an asbestos-solidifying additive storage unit 30, and a stable conversion unit 40 as shown in FIG. 4, for example. To do. Here, the transport unit 20, the asbestos-solidifying additive storage unit 30, and the stable conversion unit 40 are the same as those already described with reference to FIG. In the managed final disposal site, the asbestos-containing body (sprayed asbestos 4) of the wall surface and ceiling surface of the construction site (building 2) is the point that the scattering asbestos peeling body is enclosed in the flexible container 76. It is different from peeling work. However, the point that the scattering asbestos peel-off body 10 is enclosed by the scattering prevention sheet 8 is the same as the point that the scattering asbestos peel-off body is enclosed in the flexible container 76. Therefore, even if the scattered asbestos exfoliate has already been managed as specially controlled industrial waste at a managed final disposal site, the asbestos-containing body (sprayed asbestos 4) on the wall and ceiling of the construction site (building 2) In the same manner as the peeling operation of), the scatterable asbestos peeled body can be processed into a stable industrial waste using a waste asbestos treatment apparatus. In this case, in order to prevent scattering at the management-type final disposal site, the vicinity of the flexible container 76 that is the work target is prevented from scattering around the work site as in the case of the construction site (building 2). It is necessary to enclose the sheet 8. Further, when the asbestos peeled body 10 in the flexible container 76 becomes a large shape by the wet process and is not suitable for pneumatic transportation or powder transportation, the crusher 14 makes the suitable shape suitable for pneumatic transportation or powder transportation. It is necessary to align.

  However, it is troublesome to enclose the flexible container 76 that has been landfilled with the anti-scattering sheet 8, and it is possible to connect the conveyance unit 20 and the flexible container 76 directly with the conveyance hose 12. It is necessary to form an opening in the flexible container 76 and join it, and the work efficiency may not necessarily be high. Therefore, it is conceivable to excavate the flexible container 76 that has been subjected to the landfill treatment and directly input it into the stable conversion unit 40 to process it into a stable industrial waste in a state in which the dispersible asbestos exfoliation material does not scatter in the environment. .

  Fig. 5 shows an example of waste asbestos enclosed in a flexible container, which is suitable for processing the scattered asbestos exfoliate already managed as specially controlled industrial waste at a managed final disposal site into stable industrial waste. It is a block diagram which shows an example of a processing apparatus. The worker 78 of the waste asbestos processing apparatus moves to the management-type final disposal site 70 by the truck 60 loaded with the asbestos-solidifying additive storage unit 30, the stable conversion unit 40, and the removal filter 50. The managed final disposal site 70 is provided with a transporter such as a crane-type handler 82 that transports the flexible container 76 that has been landfilled to the funnel port 41 of the stable conversion unit 40. Here, the transport rail 80 is installed from the management-type final disposal site 70 to the parking position of the truck 60, and the flexible container 76 is transported by the crane-type handler 82 that moves along the transport rail 80. Instead of the crane-type handler 82, the operator 78 may carry out the transfer / loading operation of the flexible container 76.

  In the figure, asbestos-solidifying additive accommodation unit 30 accommodates asbestos-solidifying additive 32 and is the same as the waste asbestos processing apparatus shown in FIG. The stable conversion unit 40 is a non-sprayable asbestos obtained by solidifying the scatterable asbestos peeled body enclosed in the flexible container 76 and the asbestos-solidifying additive 32 accommodated in the asbestos-solidifying additive-containing unit 30. This is processed into a peeled body. Here, as with the waste asbestos processing apparatus shown in FIG. 1, a funnel port 41, a fixed amount input device 42, a funnel type supply port 43, an input port 44, a volume reduction processing device 45, a transporter. A pipe 46, a stable waste holding tank 47, and a pellet coating unit 48 are provided. The periphery of the stable conversion unit 40 is surrounded by a sealed casing 49 so that the scattered asbestos peeled body enclosed in the flexible container 76 is not scattered. The sealed casing 49 has openings near the funnel opening 41 and the transport pipeline 46, but is kept at a negative pressure so that the scatterable asbestos peeled body does not scatter to the outside. That is, the scattering asbestos peeling body is transported inside the sealed casing 49 by the transport pump 58 provided on the removal filter 50 side.

  The removal filter 50 removes the scattering asbestos peeling body from the air generated from the flexible container 76 when the stable conversion unit 40 processes the scattering asbestos peeling body enclosed in the flexible container 76. . Here, the removal filter 50 collects the scattering asbestos peeling body from the conveyance hose 52 that conveys the scattering asbestos peeling body 10 scattered by the stable conversion unit 40 to the removal filter 50 and the air that is conveyed by the conveyance hose 52. A collecting filter 54 for carrying out the filtration, an exhaust filter 56 for performing filtration so that the air discharged into the environment does not contain the scattering asbestos peeling body, and a conveyance pump 58 for conveying the air containing the scattering asbestos peeling body to the conveyance hose 52. ing. In addition, it is good to provide the conveyance path (not shown) which returns the scattering asbestos peeling body collected by the collection filter 54 to the funnel mouth 41 of the stable type conversion unit 40.

  In the apparatus configured as described above, the flexible container 76 that has been subjected to the landfill process is dug out and is put into the stable conversion unit 40 using the crane-type handler 82 or the like. The stable conversion unit 40 is a non-sprayable asbestos obtained by solidifying the scatterable asbestos peeled body enclosed in the flexible container 76 and the asbestos-solidifying additive 32 accommodated in the asbestos-solidifying additive-containing unit 30. Process into a peeled body. The removal filter 50 removes the scattering asbestos peeling body from the air generated from the flexible container 76 when the stable conversion unit 40 processes the scattering asbestos peeling body enclosed in the flexible container. Thus, the stable conversion unit 40 can easily manage the scatterable asbestos peeled body enclosed in the flexible container 76 from a specially managed industrial waste to a stable industrial waste and manage it as general waste. While being able to be processed into a state, the removal filter 50 prevents the scattering of the asbestos peeled body into the environment.

  FIG. 6 is a flow chart for explaining the method for treating waste asbestos encapsulated in the flexible container of the present invention. First, the truck 60 loaded with the processing equipment for the waste asbestos enclosed in the flexible container is mounted on the management-type final disposal site 70 (S302). And the repair worker 6 confirms the accommodation state of the asbestos-solidifying additive 32 in the asbestos-solidifying additive accommodation unit 30 (S304), and when the amount required for this work is not accommodated, the asbestos-solidifying additive is added. Agent 32 is replenished. In this way, the preparation stage of the waste asbestos treatment operation is completed.

  Then, the worker 78 carries out or digs out the flexible container 76 in which the scattered asbestos of the management-type final disposal site 70 is enclosed (306). The carried out flexible container 76 is transported to the stable conversion unit 40 by an appropriate transport device such as a transport conveyor (S308). And the asbestos peeling body 10 and the asbestos solidifying additive 32 enclosed in the flexible container 76 are solidified integrally and processed into a non-scattering asbestos peeling body by the stable conversion unit 40 (S310). At this time, by using the pellet coating unit 48 or the like, the plastic waste solidified into pellets by the volume reduction processor 45 is covered with a paste-like adhesive substance, or the periphery is covered with a plastic film. It is better to send it to the stable waste holding tank 47. The processed non-scattering asbestos-peeled body can be reused as fuel in the form of pellets, and is treated as general waste as a non-scattering asbestos-peeled body (S312). Moreover, when processing the scattering asbestos peeling body 10 enclosed with the flexible container 76 with the removal filter 50, the scattering asbestos peeling body 10 is removed from the air produced from the flexible container 76 (S314).

  Then, the worker 78 determines whether or not the processing operation of the flexible container 76 filled with the scattering asbestos in the management-type final disposal site 70 has been completed (S316). And if processing work is not completed, it will return to S306 and will continue carrying out and excavation work of the flexible container 76 with which scattering asbestos was enclosed. When the processing work is completed, the person in charge of the work moves the truck 60 loaded with the processing equipment for the waste asbestos sealed in the flexible container from the management-type final disposal site 70 (S318).
