Description

  The present invention provides a pedestal (hereinafter referred to as a trace amount) for cleaning and transporting a radiator such as an electric device having a trace amount of PCB adhered therein in a past use, which is used for cleaning and removing the trace amount PCB. Cleaning of PCB-attached radiator and transportation platform).

  Electrical equipment such as transformers used for power transmission and transformation used to use PCB as cooling oil and insulating oil. From the viewpoint of preventing environmental pollution, the manufacture of PCBs was discontinued in 1972, and electrical equipment such as transformers that used PCBs according to the law enacted in July 2001 was used after removing the PCB insulating oil. The extracted PCB liquid was to be stored. At the same time, the inside of the transformer container and the inside of the transformer with the PCB adhered to the surface were kept in their original form because the method for treating the trace amount of PCB was not established. In recent years, a processing method has been developed for this small amount of PCB, and it has been gradually applied to electric equipment such as a transformer.

When processing electrical equipment with a small amount of PCB attached, for example, when discarding a large transformer, if its weight is 10 tons or more, the outer shape is too large and there are restrictions due to the Road Transportation Law. However, it is difficult to transport the same as it is to the PCB processing plant. Therefore, electrical equipment is once disassembled and divided and transported. At that time, in order to prevent a small amount of PCB adhering to the inner wall surface of the container and the built-in parts from leaking outside during transportation, disassembly and transfer, the electrical equipment that becomes waste is cut down and dismantled to reduce its size. , housed in a dedicated container about capacity 1 m ^3, it is transported or transferred to ensure tightness.

  Patent Documents 1 to 3 disclose examples of a method and an apparatus for treating electric equipment to which such a small amount of PCB is attached. In the method of dismantling a PCB-enclosed device described in Patent Document 1, the device enclosing a PCB is dismantled by sawing or the like. At that time, the PCB is sawed as a cooling liquid.

  In addition, in the method for treating low-concentration PCB-containing insulating oil-filled equipment described in Patent Document 2, in order to eliminate the need for a large-scale treatment plant, the concentration is reduced to below the legal standard by irradiating gamma rays without extracting PCB insulating oil. Let me. Furthermore, in the detoxification processing system for equipment using PCBs described in Patent Literature 3, the PCB remaining in the container and the internal member after the PCB is extracted is replaced with a catalyst tank, a microwave irradiation device, a cooler, a heat retaining member, a heater, A system including means such as a heat pump is configured and processed.

  Patent Documents 4 to 6 describe examples of transport containers for transporting hazardous materials, transporting liquids and solids required to prevent leakage to the outside, or prevention of contamination from the outside.

JP 2005-95710 A JP 2010-269283 A JP 2008-272550 A JP-A-2000-7084 JP 2011-526231 A JP-A-5-246482

  In the method of disassembling a device enclosing a PCB described in Patent Document 1, a great deal of labor is required to disassemble the device, and there is no disclosure of detoxification processing and transportation of the disassembled device. That is, the dismantled equipment may also contaminate the surrounding environment, so that it is necessary to pay sufficient attention to detoxification treatment and transportation, but these are not considered.

  Further, the methods described in Patent Documents 2 and 3 require a gamma ray irradiation device or a microwave irradiation device as a processing device. Therefore, if the electrical equipment is relatively small, such as a pole transformer, the processing equipment can be reduced in size and the processing equipment can be moved.However, in the case of a medium-sized or large-sized transformer, the irradiation equipment is also required. It is difficult to move the irradiation device to a place where the transformer is stored in a large size. In addition, these patent documents 2 and 3 do not consider the movement of a transformer as a processing object to a processing place.

  Patent Literatures 4 to 6 disclose sealed containers for transporting dangerous goods and the like. However, since these do not relate to large-sized electric equipment to which a small amount of PCB is attached, consideration is given to how to prevent environmental pollution and accommodate it in a container, for example, in the case of a large-sized transformer. Absent.

  The supply pipe 701 is supplied with a PCB cleaning liquid from a PCB cleaning liquid supply hose (described below) 862 of a PCB processing apparatus (described below). In the recovery pipe 703, the recovery liquid after cleaning the inside of the radiator is sent to a PCB cleaning liquid recovery hose (described later) 863 of the PCB processing apparatus.

  In the above configuration, when the PCB cleaning liquid is supplied from the PCB processing apparatus, the cleaning liquid is supplied to the lower connection pipe 803 via the supply flexible pipe 711. At this time, since the supply connection portion 805 is connected to a position eccentric below the lower pipe flange 807, the PCB cleaning liquid is supplied from the supply connection portion 805 to the inner bottom of the lower connection pipe 803. With the supply, the PCB cleaning liquid gradually rises from the bottom of the inside, fills all the fins of the radiator 801, further rises and flows into the upper connection pipe 802 from below to fill the inside.

  Since the recovery connection portion 804 is eccentrically connected to the upper side of the upper pipe flange 806, when the upper connection pipe 802 is filled with the PCB cleaning liquid, the PCB cleaning liquid on the uppermost liquid level in the upper connection pipe 802 is connected for recovery. It overflows from the part 804 and flows out. The PCB cleaning liquid that has overflowed from the collection connection portion 804 is collected by the collection pipe 703 via the collection flexible pipe 712, and is sent to the PCB processing apparatus.

  As described above, since the collecting connection portion 804 is connected to the eccentric position above the upper pipe flange 806 and the supply connecting portion 805 is connected to the eccentric position below the lower pipe flange 807, the PCB cleaning liquid is supplied to the radiator 801. The entire inner surface from the inner bottom to the ceiling can be contacted, and the trace PCB adhered to the inner surface can be effectively cleaned.

  In the PCB processing apparatus, the recovered PCB cleaning liquid is regenerated and supplied to the supply pipe 701 again, or the collected PCB cleaning liquid is stored and another new PCB cleaning liquid is supplied to the supply pipe 701. .

  FIG. 8 is an explanatory diagram of installing the radiator in a state where the gantry alone is laid sideways. When installing the radiator on the gantry, the gantry 100 shown in FIG. 1 is laid down on its side, and the radiator 801 is placed on the gantry from above with the radiator 801 suspended. Then, in this state, the upper supporting frame is fixed to the upper horizontal frame 104 via the upper fire receiving piece 603, and the upper part of the radiator 801 is supported. Further, the lower support frame is fixed to the lower horizontal frame 205 via lower fire receiving pieces 606 and 609 to support the lower portion of the radiator 801.

  Further, in a state where the stand 100 alone is placed sideways, both ends of the supply flexible pipe 711 are connected to the lower pipe flange 807 of the lower connection pipe and the connection port 702 of the supply pipe 701 by a coupler. On the other hand, both ends of the recovery flexible pipe 712 are connected to the upper pipe flange 806 of the upper connection pipe 802 and the connection port 704 of the recovery pipe 703 by couplers. At this time, the opening directions of the connection pipes 802 and 803 of the radiator 801 and the opening directions of the connection ports 702 and 704 are directed to the outside of the gantry (the outside of the gantry is vertically oriented in FIG. 8). Therefore, the connection work of each flexible pipe with the coupler is in the same direction.

  In the work of installing the radiator on the gantry with the gantry 100 placed sideways, the work position is low and the work direction is downward, so that work safety can be ensured and work efficiency is improved. In addition, since the connection directions of the supply flexible pipe 711 and the recovery flexible pipe 712 at the respective couplers are the same (vertical direction in FIG. 8), connection work in the same direction is sufficient, and work safety can be ensured. Work efficiency is improved.

  Next, as shown in FIG. 9, the stand 100 on which the radiator is installed is lifted by the wire 850 via the metal fittings 107 to 110 and raised. In this erecting, if the lifting height of the upper erecting bracket 107 is set higher than the lifting height of the lower erecting bracket 108, the erecting can be easily and safely performed. Next, as shown in FIG. 10, the gantry 100 alone is connected back to back to form a gantry on which a radiator is installed.

FIG. 11 is an explanatory diagram in which the installation and gantry shown in FIG. 10 are lifted and loaded on a trailer that is a transport vehicle . The connecting gantry is lifted by the wire 851, installed on the metal tray 861 for preventing leakage of the transport vehicle 860, and fixed by a predetermined wire.

Figure 12 is an explanatory view of a state of connecting the radiator frame stacked on the transport vehicle to the cleaning device. The connecting stand provided on the metal tray 861 for preventing leakage is connected to a PCB cleaning liquid supply hose 862 extending from the PCB processing device 865 by the transporting vehicle 860. Then, the supply pipe 701 of the connection stand and the PCB cleaning liquid supply hose 862 of the PCB processing device 865 are connected by a coupler, while the recovery pipe 703 and the PCB cleaning liquid collection hose 863 of the PCB processing device 865 are connected by a coupler.

  A PCB cleaning liquid is supplied to the inside of the radiator 801 to perform cleaning for a predetermined time, and a small amount of PCB attached to the inside of the radiator 801 is processed and removed. Therefore, the user transports the entire vehicle 860 to the vicinity of the PCB processing device 865. In the case of the present embodiment, the cleaning liquid is discharged from the supply pipe and the recovery pipe after the operation is continued for about 8 hours and the cleaning is completed. As a result, the trace amount of PCB is almost completely removed, which is below the allowable standard for waste, and can be discarded as general industrial waste.

  The radiator that has become general industrial waste is transported by the transport vehicle 860 and disposed at the metal disposal site while being installed in the gantry.
