Abstract

The invention relates to the technical field of civil air defense equipment, and relates to a civil air defense filter absorber, which includes a box body and a filter mechanism, one end of the box body is provided with an air inlet, and the other end of the box body is provided with an air outlet port; the filter The mechanism is arranged in the box; including a blocking mechanism arranged in the box, the blocking mechanism includes a baffle and a first non-woven fabric, the baffle is arranged in the box and is located between the air inlet and the Between the filter mechanisms, a first air hole is opened on the baffle; the first non-woven fabric is arranged on the baffle. The blocking mechanism provided in the present invention can block dust, thereby improving filtering efficiency.

Description

technical field [0001] The invention relates to the technical field of civil air defense equipment, in particular to a civil air defense filter absorber. Background technique [0002] At present, there are many kinds of filtering and absorbing devices on the market. The filtering and absorbing devices in the prior art are devices that can effectively filter out toxic gases, radioactive dust and soot, and can provide clean air. The special filter and absorbing device for civil air defense is a kind of Civil air defense filter absorber Special filter absorber for civil air defense is the core product of wartime ventilation system. It is mainly used in the drug-related ventilation system of civil air defense projects, which can effectively filter the poisonous smoke, poisonous fog, biological aerosol and radioactive dust in the poisoned air, and permanently filter the air to make it clean. [0003] At present, the Chinese invention with the authorized publication number CN1083...
