Description

Multiplex type filter assembling workbench for nuclear power station

Technical Field

The utility model belongs to the technical field of nuclear power station ventilation system technique and specifically relates to a nuclear power station is with multiplexing type filter equipment workstation.

Background

A nuclear power plant refers to a facility that converts nuclear energy into electrical energy by appropriate means. Nuclear power plants replace the boilers of thermal power plants with nuclear reactors, and generate heat by the special form of "burning" of nuclear fuel in the nuclear reactors, so that the nuclear energy is converted into heat energy to heat water and generate steam. With the increase of the number and scale of nuclear power stations in China, the 'three wastes' (radioactive solid wastes, radioactive waste liquids and uranium ore waste rock and waste residues) generated in the nuclear power operation process are multiplied. In order to avoid possible radioactive substances in the controlled area from escaping to the environment during the operation of the nuclear power plant, the nuclear power plant is provided with a special ventilation system and an air filtration device, so that a large number of ventilation filters are replaced each year, and the filters temporarily store as radioactive waste due to the possibility of containing radioactive particles, so that a large amount of radioactive solid waste is generated each year.

In order to solve the problem, a reusable filter for a ventilation system of a nuclear power plant is available on the market, and the reusable filter generally comprises a detachable metal frame and a filter element, wherein the filter element is adhered and fixed in the metal frame through hot melt adhesive. The basic idea of filter reuse is that after part of metal frame of the filter is disassembled, the filter is placed in a preset temperature environment to melt the hot melt adhesive, and then the filter element is extruded out of the frame through a pressure mechanism; and further disassembling the metal frame into sheets or plates, and performing surface degumming and kernel removal radiation treatment. When the filter element is assembled, the processed sheet or plate is assembled into a metal frame, a new filter element is arranged in the metal frame, and then glue is poured, so that the filter element and the inner surface of the metal frame are fully bonded and fixed in a natural environment, and the filter element can be put into a nuclear power station again. In the above process, since the filter is very heavy, the assembly of the filter needs to be operated from a plurality of angles and directions, and when the filter parts are assembled, the filter is easy to shake and shift, so that the assembly efficiency is low.
