an air purification device

Abstract

The invention discloses an air purifying device which comprises an outer shell. An air guide cover is arranged at the lower end of one side of the outer shell, and a device body is arranged in the outer shell; the inner lower end of the device body is provided with an absorption liquid storage chamber; an air inlet pipe is arranged on one side of the absorption liquid storage chamber; an air distribution plate is arranged at the inner lower end of the absorption liquid storage chamber; dust plates are staggered at intervals in the absorption liquid storage chamber sequentially from top to bottom; a liquid distribution plate is arranged above the dust plates, and a water inlet end of the liquid distribution plate is connected with a water pump; a first filter layer is arranged above a waterproof air-permeable membrane which is arranged above the liquid distribution plate; a photocatalytic oxidation chamber is formed above the first filter layer; photocatalytic plates are transversely staggered at intervals in the photocatalytic oxidation chamber sequentially from top to bottom; each photocatalytic plate is provided with a penetration hole, and ultraviolet light tubes are arranged inthe penetration holes; a second filter layer is arranged above the photocatalytic oxidation chamber, and the top end of the device body is provided with an air outlet pipe. The air purifying device is high in treatment efficiency, pollutants in treated air are almost all removed, and an extensive application prospect is achieved.

Description

technical field [0001] The invention belongs to the technical field of air pollution treatment, and in particular relates to an air purification device. Background technique [0002] Effective control of air pollution, especially indoor air pollution, which has serious harm to human body, has become a hot issue that people pay more and more attention to. Indoor air pollutants are mainly carbon monoxide, nitrogen oxides, hydrocarbons, sulfur oxides and particulate matter, especially PM2.5. At present, more than 300 volatile organic compounds have been identified indoors, mainly including aliphatic hydrocarbons, aromatic hydrocarbons, Chlorinated hydrocarbons, aldehydes and ketones, therefore, indoor air pollution is a growing problem. [0003] The method that is used for indoor air purification can be divided into ventilation type, filter type, adsorption type and catalytic purification type etc. according to the action principle, but all has its own defect. The ventilation...
