Study on the Renewable Toxic Gas Filtering Apparatus

To cope with biochemical terrorism attack and public health emergency, it is urgently necessary to develop a kind of renewable toxic gas filtering apparatus in order to solve problems of regular replacement and short protective time of existing toxic gas filtering apparatus. Based on the analysis of the deficiency of existing toxic gas filtering apparatus, a kind of renewable toxic gas filtering apparatus was developed using the technology of variable pressure. The contaminated air could be purified by renewable toxic gas filtering apparatus finally provide pure air for persons in the vessel compartment. Renewable toxic gas filtering apparatus can satisfy the NBC protective of civil building.
