Air purification device for indoor formaldehyde removal

Abstract

The invention provides an air purification device for indoor formaldehyde removal. A settling chamber, a purification chamber and an air supply channel which are distributed from bottom to top are arranged in a box body, a first filter plate is separated between the settling chamber and the purification chamber, and an air feeder is separated between the purification chamber and the air supply channel; an exhaust fan is arranged on the side surface of the settling chamber, a Lorentz settling assembly is arranged in the settling chamber, and Lorentz force of the Lorentz settling assembly is perpendicular to a rotating shaft of the exhaust fan; a second filter plate is arranged in the purification chamber, the second filter plate is of a net-shaped filter structure woven by warps and wefts, each warp comprises a first thread main body and a photocatalyst thread wound outside the first thread main body, each weft comprises a second thread main body and a metal silver thread wound outside the second thread main body, and an ultraviolet light activation module is arranged on one side of the second filter plate; and a charged particle generator is arranged in the air supply channel. Most harmful substances can be settled, the burden of the filter plates is reduced, the working performance of the second filter plate can be maintained without replacement, and the air purification device is convenient to use and environmentally friendly.

Description

technical field [0001] The invention relates to the field of air purification, and specifically discloses an air purification device for indoor aldehyde removal. Background technique [0002] The air purification device, as the name suggests, is a device used to purify the air. It mainly circulates and purifies the indoor air through the air extraction mechanism and the air supply mechanism. [0003] With the continuous improvement of people's living standards, people pay more and more attention to their health. Indoor air pollution is a problem that people are very concerned about and needs to be solved urgently. There are thousands of indoor air pollutants, such as kitchen fume, fiber dander, formaldehyde, ammonia, etc., especially formaldehyde, which is extremely harmful to the human body and induces health problems of varying degrees. [0004] In the prior art, the air purification device mainly uses filter screens of different densities to filter and purify the air. Th...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, the air purification device mainly uses filter screens of different densities to filter and purify the air. The main filter and adsorption material is disposable purification materials such as activated carbon. When the service life such as saturation is reached, the filter screen needs to be replaced. Inconvenient and not environmentally friendly
