Abstract

The invention discloses a renewable gas particulate filtering unit. The renewable gas particulate filtering unit comprises a polluted air inlet, a primary filter, a compressor, a gas-water separator, a freeze drying machine, a secondary filter and a tertiary filter which are connected by a main pipeline in sequence, wherein the tertiary filter is respectively connected with a first pipeline and a second pipeline through the main pipeline, the tail end of the first pipeline and the tail end of the second pipeline are respectively connected with a flow control valve, and the flow control valve is connected with a clean air outlet. The renewable gas particulate filtering unit can regenerate a filter absorber and be recycled, thus solving the problem that antivirus time is limited by the adsorption capacity, and significantly reducing the follow-up security demands of resupply, replacement and treatment of the filters of current activated carbon based nuclear biochemical systems.

Description

technical field [0001] The invention relates to the technical field of nuclear, biological and chemical protection, in particular to a device capable of filtering and purifying air polluted by nuclear, biological and chemical pollutants. Background technique [0002] The so-called regenerative poison filter ventilation device means that the core component of the device is a regenerative filter absorber, which works alternately through two independent filter absorbers. When working, one filter absorber is in the working state to filter and purify pollutants, while the other filter absorber is regenerated through pressure-changing and temperature-changing technology, and finally achieves the purpose of circulating, filtering and purifying the air, so as to provide air for cabins or bunkers. Personnel provide clean air. [0003] At present, the existing poison filtering and ventilation devices all use one-way activated carbon filters. After working under nuclear, biochemical a...
