摘　　要：现有通风系统过滤器将玻璃纤维滤纸采用密封胶粘接到金属壳体上,过滤器失效后整体淘汰,造成大量的固体废物。由于密封胶难以从壳体上去除干净,金属壳体无法重复使用,从而导致了高昂的固体废物处理费用。新式可复用外壳核级高效过滤器通过改变原有的内部结构框架,使内部滤芯可以进行更换而不对金属外壳造成结构损坏,从而降低通风系统过滤器的固废产量和处置成本。The filter of the existing ventilation system uses sealant to glue the glass fiber filter paper to the metal shell,and the whole filter is eliminated after failure,resulting in a large amount of solid waste.Sealant is difficult to be removed from the shell,so the metal shell cannot be reused,resulting in high solid waste disposal costs.By changing the original internal structure frame,the new reusable-shell nuclear grade HEPA filter can replace the in‐ner filter element without damaging the structure of the metal shell,so as to reduce the solid waste production and disposal costs of the filter of the ventilation system.
