Description

  The present invention relates to a PCB waste detoxification processing facility for detoxifying PCB waste, and in particular, a worker who connects each processing process line via a three-dimensional automatic warehouse that automatically receives and unloads processing objects. The present invention relates to a PCB waste detoxification treatment facility that can eliminate PCB exposure to human bodies and eliminate human error.

  PCB (polychlorinated biphenyl) has been used as insulation oil for electrical equipment such as transformers, condensers, ballasts for discharge lamps, lubricating oil for pumps, heat medium for air conditioning equipment, etc., but it is toxic and persistent. Therefore, the production of PCBs and products using PCBs has been stopped because they accumulate and cause great damage to human health and living environment. PCB waste, such as waste PCB, waste oil containing PCB, and PCB contaminants, is stored in a designated storage facility and detoxified by a PCB waste detoxification facility.

  FIG. 4 is a diagram illustrating an example of a processing process of a processing object in a PCB waste detoxification processing facility.

  The processing object received in the receiving process line is transported to the dismantling process line after sorting by sorting and sorting. In the demolition process line, oil is drained to remove the waste PCB, and further, the PCB that adheres to and is impregnated in the object to be processed is removed efficiently, and then disassembled, cut, separated, crushed and separated. In the dismantling process line shown in FIG. 4, for example, in dismantling B, the transformer is dismantled and separated into impregnating members, non-impregnating members, and other A, B, C, etc. Dismantled and sorted.

  The dismantled processing object is transported to the detoxification process line cleaning A, cleaning B or vacuum heating separation process, and is washed with a cleaning liquid to remove adhered or impregnated PCB, or heated, for example, PCB is removed by evaporating, condensing and liquefying PCB by vacuum heat separation. The removed PCB is subjected to decomposition treatment (liquid treatment) in the same manner as the drained PCB.

  The processed object to be processed is transported to the acceptance / rejection determination process line, and the acceptable product that has been subjected to the detoxification completion determination (graduation determination) below the determination criterion of the processed PCB waste (so-called graduation criterion) by the determination waiting device is unloaded, Products that fail graduation judgment are returned to the detoxification process line and detoxified again.

An example of a transformer detoxification method is disclosed in Patent Document 1. In the transformer detoxification method of Patent Document 1, the drain cock of the transformer is opened, waste oil is extracted from the transformer, and the extracted PCB oil is decomposed. On the other hand, the transformer from which the waste oil has been extracted is further disassembled and disassembled into metal containers, iron cores, coils, etc., and the coils are further disassembled and classified according to the material such as copper wire, paper, wood, etc., and then washed and separated. Processing is performed. And the metallic container, the iron core, and the copper wire of the coil are taken out on condition that the processing reference value is cleared, and become a metallic byproduct. Non-metallic members and cleaning liquid are decomposed together with waste oil and taken out as non-metallic by-products such as hydrochloric acid, carbon dioxide gas, and oil from which PCBs have been removed. The PCB processed product is repeatedly subjected to the detoxification process until the PCB processed product graduates.

A container that is emptied by the refilling device may be temporarily stored, and a transport device that transports the container to the dismantling process line may be arranged.

  The present invention is based on the processing plan set by the three-dimensional automatic warehouse by arranging each process line around the three-dimensional automatic warehouse and connecting the process lines in the atmosphere where the PCB is exposed to the human body via the three-dimensional automatic warehouse. Processing lot summary, processing line recombination, and processing order recombination of processing objects can be automatically performed. Moreover, it becomes possible to eliminate an operator's intervention as much as possible by couple | bonding via a conveying apparatus between each line and the three-dimensional automatic warehouse between each line. In addition, by connecting with each three-dimensional automatic warehouse with a transport device, products that have failed graduation judgment can be automatically returned to the three-dimensional automatic warehouse for detoxification treatment and reprocessed in the detoxification treatment process line. Thus, operator intervention is eliminated. As a result, it is possible to prevent the PCB from being exposed to the human body, and it is possible to prevent the occurrence of human error by fully automatic operation.

  In addition, if you connect a three-dimensional automatic warehouse for judgment waiting, a three-dimensional warehouse that stores the dispensing container, and a refilling device that refills the processing object that has passed to the dispensing container, the graduation judgment-accepted product is refilled unattended and delivered outside the facility. be able to.

  Moreover, since the storage space can be reduced by introducing a three-dimensional automatic warehouse, the installation area and the building scale can be reduced, the useless space can be eliminated, and the ventilation air volume can be reduced.
