Abstract

The invention provides an air purification device for removing low concentration formaldehyde and benzene series. The device comprises a casing provided with an air inlet and an air outlet communicating with a space to be purified, a pretreatment bin arranged in the casing and located behind the air inlet, Wherein a physical adsorption layer for adsorbing formaldehyde in air and benzene series molecular particles in air is arranged in the pretreatment bin, a photocatalyst reaction bin arranged in the casing and behind the pretreatment bin, and an exhaust gas recovery bin which is arranged in the casing, behind the photocatalyst reaction bin and in front of the air outlet and is used for recovering and trapping trace amounts of formaldehyde and benzene molecular particles undecomposed catalytically by the photocatalyst reaction bin. The air purification device utilizes a pretreatment bin-photocatalyst reaction bin-exhaust gas recovery bin three-grade composite bin structure to solve the technical problem that the existing photocatalyst technology can not clear the low concentration of formaldehyde and benzene series particles in the air.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to an air purification device for removing low-concentration formaldehyde and benzene series in the air. Background technique [0002] Formaldehyde and benzene series are highly volatile organic compounds with a high degree of pollution, and are one of the main pollutants in indoor air. Among them, formaldehyde has a great impact on human health, and has a strong stimulating effect on human mucous membranes and skin. When inhaled at high concentrations, severe respiratory tract irritation and edema will occur, causing eye irritation and headaches. Inhalation of low concentrations can cause persistent headache, weakness, insomnia, etc. Long-term exposure can cause dermatitis, abnormal lung and liver function, abnormal immune function, central nervous system, and damage the genetic material in cells, which is a possible carcinogen. Photocatalyst is a general term for photo-...
