Equipment and method for disassembling low-radioactivity folding type waster filter

Abstract

The invention discloses equipment and method for disassembling a low-radioactivity folding type waster filter. According to the equipment and method, the folding type waster filter to be disassembled is installed into a disassembling system, after an external package is disassembled, a shell cutting machine is used for transversely cutting the two ends of each of two longitudinal beams in a rectangular frame type metal shell of the folding type waster filter to separate out transverse beams at the front and back end, a core cutting machine is used for conducting linear cutting on combining seams of the inner sides of the two longitudinal beams in the rectangular frame type metal shell of the folding type waster filter and a core of a filter element to separate out the core of the filter element, finally the disassembled metal shell is heated by a tunnel type oven to change the caking property of attached glue, and separation of the glue and the metal shell is achieved through electric shovel glue in a shovel glue negative pressure ventilation cabinet. According to the equipment and method, the folding type waster filter can be disassembled before waste is treated, classification of metal materials and nonmetal materials is achieved, and the beneficial effects of being high in automatic degree, high in efficiency, safe, energy-saving, environment-friendly and the like are achieved.

Description

technical field [0001] The invention relates to a device and method for dismantling decommissioned low-radioactivity folded waste filters in nuclear air and gas treatment systems, more specifically for specific activity less than or equal to 4×10 6 Bq / kg (GB9133-1995, ie radioactive solid waste Class I) folded waste filter equipment and method for dismantling and dismantling and material classification before waste treatment. Background technique [0002] In accordance with the country's long-term plan to develop clean nuclear energy and expand the nuclear industry, with the rapid development of nuclear power technology, filters used in nuclear facilities, especially low-radioactive waste filters, are being decommissioned and piled up in large quantities. For low-radioactive waste round filters, domestic nuclear industry units simply pack radioactive waste round filters into 200L standard waste barrels for storage. A standard R series round filter (dimensions: φ518× 624), ...

AI Technical Summary

Problems solved by technology

For low-radioactive waste round filters, domestic nuclear industry units simply pack radioactive waste round filters into 200L standard waste barrels for storage. A standard R series round filter (dimensions: φ518× 624), a standard waste bin can only hold one round filter, the storage volume is large and takes up a lot of storage space

In addition, according to relevant information, it costs 70,000 yuan to dispose of a 200L standard waste bin equipped with an R-series circular filter, which is expensive.
