Abstract

The invention belongs to the field of nuclear power plant radioactive aerosol treatment and particularly relates to a filter drainage-exit-free filter element for nuclear power plant radioactive aerosol treatment. The filter drainage-exit-free filter element comprises an upper end cover (1), a sealing gasket (2), sunk screws (3), connecting rods (7), sealant (9), a lower end cover (10) and a filtering assembly. A round hole is formed in the center of the upper end cover, and a circle of sealing gasket (2) is arranged on the upper surface of the upper end cover. A round hole is formed in the center of the lower end cover (10). The position between the upper end cover (1) and the lower end cover (10) is supported by the six connecting rods (7). The filtering assembly is in a vertically through hollow cylinder barrel shape, and the upper end and the lower end of the filtering assembly are fixed to the upper end cover (1) and the lower end cover (10) respectively through the sealant (9).

Description

technical field [0001] The invention belongs to the field of radioactive aerosol treatment in nuclear power plants, and in particular relates to a filter element without a drain for the treatment of radioactive aerosol in nuclear power plants. Background technique [0002] High-efficiency filters play an important role in the radioactive aerosol treatment process of nuclear power plants. Tianwan Nuclear Power Station has two high-efficiency filter elements designed and supplied by Russia in the primary circuit storage tank exhaust purification system for purifying exhaust gas. radioactive aerosols. Due to the long service time, the filtration efficiency of the filter element is deteriorating at present, and the traditional filters of domestic manufacturers have no similar products. , developed a new filter element for radioactive aerosol treatment filters in nuclear power plants. Contents of the invention [0003] The purpose of the present invention is to provide a kind...
