Air filtering and absorbing device

Abstract

The invention discloses an air filtering and absorbing device. The air filtering and absorbing device comprises a filter shell, a free radical generator, a fine filtering unit and a toxin filtering unit, wherein an air inlet and an air outlet are formed in two ends of the filter shell; an inflow air diffuser is fixedly arranged between the outlet of the air inlet and one end of the filter shell; an outflow air diffuser is arranged between the other end of the filter shell and the inlet of the air outlet; the free radical generator extending into the inflow air diffuser is arranged on the outerwall of the inflow air diffuser; the fine filtering unit is fixed on the inner wall of one end of the filter shell and close to the outlet of the inflow air diffuser; the toxin filtering unit is arranged in the part, located between the fine filtering unit and the inlet of the outflow air diffuser, of the filter shell; the end of the air inlet and the end of the air outlet are each provided withan inlet / outlet adapter. According to the air filtering and absorbing device, the stroke and time of air filtering are increased, air purification is more thorough, dust in air can be effectively filtered and purified, and bacteria, viruses and the like in the air are killed.

Description

technical field [0001] The invention belongs to the technical field of air defense filter equipment, and in particular relates to an air filter absorber. Background technique [0002] Civil air defense facilities are public safety buildings built to deal with special environments such as wartimes and disasters. Its system is complex and its structure is tight. It needs to fully consider the special environment of wartimes and disasters during design and construction, and requires a special ventilation system. , and the air filter absorption equipment is an indispensable part of the special filter absorber for civil air defense, and it is also an important equipment in the drug-related ventilation system of civil air defense projects. It can effectively filter toxic smoke, radioactive dust and other harmful substances in the poisoned air. , to provide filtered clean air for the internal personnel of civil air defense projects; for this reason, in times of war, the air is full...

Problems solved by technology

However, during the use of existing filtering and absorbing equipment, due to the high air humidity, dust, and bacteria in the basement, these pollutants usually gather on the filtering and absorbing equipment during its work, so the filtering and absorbing equipment must be regularly checked. Cleaning, if it is not cleaned, it will lead to unsatisfactory filtering effect. Such frequent disassembly and installation will also cause certain damage to the dust filter itself, which will affect the degree of air purification. It is difficult to replace and replace, the efficiency of air purification and absorption is not high enough, and it cannot adapt to the requirements of various environments. It is urgent to improve the existing
