With the continuous improvement of the environment, the PM2.5 is effectively controlled. In the application of an air conditioner and an indoor fresh air system, the indoor PM2.5 is not the key point of air purification. Formaldehyde and TOVC produced by decoration pollution and bacterial viruses spread in the air become important killers affecting the health of people. The traditional formaldehyde removing method for the product adopts chemical spray covering and activated carbon adsorption of a purifier, and has the defect that the chemical spray covering does not really remove formaldehyde. Formaldehyde is released into the room as is after a few days. The activated carbon net can not adsorb formaldehyde for a long time, and the adsorption saturation fails after several months. The spraying and frequent replacement of the activated carbon filter element must be carried out continuously. The user uses inconveniently and frequently changes the filter screen and drops into with high costs. The traditional product sterilization and disinfection adopts photocatalyst and filter screen filtration, the low efficiency of photocatalyst sterilization has been eliminated by the market, and the filtration is only to concentrate the indoor dispersed bacteria and viruses on the filter screen and not kill them, causing the risk of secondary pollution to be great.

The main element of all organic pollutants (bacteria, viruses, formaldehyde, ammonia, benzene, TVOC and the like) is C, H (carbon and hydrogen), and the molecular structure is relatively stable. The effect of the light plasma is to tear the stabilized hydrocarbon molecule chains: the organic matter (hydrocarbon) is subjected to a photosensitization process under the irradiation of ultraviolet light with a specific wavelength (UVC 254nm) and a specific intensity, namely, molecules of the organic compound absorb photons with a specific wavelengthAfter the energy, the molecular chain is torn and decomposed into ions, free atoms, excited molecules or neutral molecules. UVC ultraviolet rays irradiate air entering a machine body, the irradiated air generates high-energy-level light plasma, and the sterilization and disinfection efficiency (tearing pollutants) of the high-energy-level plasma is 1000 times that of other physical and chemical sterilization technologies. After the molecular chain of the pollutant is torn, another ultraviolet lamp tube is arranged in the box body, and ultraviolet light with specific wavelength (VUV 185nm) and specific intensity is emitted to irradiate the air entering the machine and oxygen molecules (O) in the air2) Can become ozone (O) after absorbing photon energy3) And atomic oxygen (O). These elements are chemically very reactive and strongly oxidizing, and are strong oxidizing agents capable of oxidizing all organic substances by photosensitive decomposition products (UVC tear-off action: decomposition of contaminants into ions, free atoms, excited molecules or neutral molecules) into water vapor (H)2O) and carbon dioxide (CO)2) And the like. The purpose of thoroughly removing the pollutants is achieved.
