Embodiment 1
[0038] This embodiment provides a method for reusing high-efficiency filter housings in nuclear power plants. The used waste high-efficiency filter housings are first disassembled, and then the filter plate is stripped from the filter material, and then the radioactive contamination is measured. Filter plates and mounting plates that are not polluted or less polluted are reassembled and used.
[0039] The high-efficiency filter housing in this embodiment is improved, and the high-efficiency filter housing is assembled from a detachable filter plate and a mounting plate. The filter plate and installation plate are made of stainless steel, and require a 5-year cycle, which is reusable. It can not only increase the mechanical strength of the frame, but also facilitate the decontamination and cleaning of the surface when the filter material is repeatedly bonded.
[0040] Such as figure 1 As shown, the method for reusing the high efficiency filter housing of the nuclear power pla...
Embodiment 2
[0067] Such as image 3 As shown, the method for reusing the high efficiency filter housing of the nuclear power plant provided in this embodiment includes the following steps:
[0068] S201: disassemble the high-efficiency filter housing;
[0069] Disassemble the high-efficiency filter housing after filtration, and disassemble the assembled filter plate and mounting plate by removing the bolts. The filter plate and mounting plate are handled separately.
[0070] S202: Peel off the filter material on the filter plate;
[0071] Peel off the bonded filter plate and filter material that needs to be replaced after filtration. The stripping environment must be carried out in a room or equipment with negative pressure. In a negative pressure environment, it can prevent radioactive dust from spilling during the stripping process. Because the filter material is firmly bonded to the filter plate. The directly bonded filter material needs to be peeled off by heating with a heater, o...
Embodiment 3
[0089] This embodiment provides a high-efficiency filter housing for a nuclear power plant. The high-efficiency filter housing for a nuclear power plant is a part of the high-efficiency filter, and the high-efficiency filter includes a housing and a filter element.
[0090] Such as Figure 4 , Figure 5 and Image 6 As shown, the nuclear power plant high-efficiency filter housing of the present embodiment includes two filter plates 1 and four mounting plates 2, two filter plates 1 have filter holes, and are bonded with filter materials, and the two filter plates 1 are installed on At the front and back positions, the four mounting plates 2 are respectively installed at the four positions of up, down, left, and right between the two filter plates 1 . Between the filter plate and the mounting plate 2, and between the mounting plates 2 are detachably assembled together by bolts or screws.
[0091] Both the filter plate 1 and the mounting plate 2 are made of stainless steel, an...
