Indoor photocatalysis air purification device

Abstract

The invention relates to an indoor photocatalysis air purification device. The air purification device comprises an air purification device shell, a fiber filter layer, an HEPA net filter layer and anadsorption layer, wherein a fan is arranged behind the air purification device shell, and an air inlet is just formed in the front surface of device. According to the invention, gas firstly enters the fiber filter layer, so large solid substances such as dust and hair in the air are filtered out; then, the gas passes through an HEPA net, so pM2.5 particles in the gas are removed; the gas in whichimpurities are basically removed enters a photocatalysis system; an ultraviolet lamp source is arranged on the inner wall of the photocatalysis system, a plurality of layers of flat catalysis plateswhich are parallelly arranged in a trapezoidal shape are arranged at the center of the photocatalysis system, and catalysis space is distributed in an S shape, so the residence time of air is prolonged, and photocatalysis efficiency is improved; and an activated carbon adsorption layer is arranged at an outlet, so VOCs and intermediate products which are not purified by photocatalysis are prevented from being discharged into indoor air. The air purification device of the invention provides an effective solution for indoor air purification.

Description

technical field [0001] The invention belongs to the technical field of air purification, and in particular relates to a photocatalytic air purification device for efficiently purifying particulate matter and harmful gases in the air by using multiple technologies such as photocatalytic reaction, filtration, and activated carbon particle adsorption. Background technique [0002] With the development of society, people spend more and more time indoors, and the impact of indoor air quality on people's health and comfort is becoming more and more significant. Long-term exposure to indoor air pollutants has a certain impact on human health. In severe cases, it can lead to indoor air syndrome, construction-related diseases, and even cancer. VOCs and PM2.5 are the main pollutants of indoor air, which mainly come from building decoration materials and furniture. There are more than 300 types of VOCs in various indoor environments. Mainly aliphatic hydrocarbons, aromatic hydrocarbon...

Problems solved by technology

The adsorption method mostly uses activated carbon. After the adsorption carbon is saturated, not only can it no longer be adsorbed, but it will also become a source of pollution. For the entire environment, it only transfers pollution and does not completely degrade it.

Ozone technology mainly has the functions of sterilization, disinfection, and deodorization. It has low degradation efficiency for VOCs, and ozone is harmful to the human body and the environment. If it is accidentally leaked, it may cause greater harm.
