The invention relates to a vehicle air purification system, belongs to the field of air purifier and in particular relates to a vehicle air purification system integrating nanometer photocatalytic air purification technology, low-temperature plasma technology and active carbon adsorption technology into a whole. The system comprises a fan for introducing polluted air into the purification system; the inside of the purification system is provided with a plasma electrode structure and a catalyst membrane 5; an ultraviolet lamp 4 is arranged between the plasma electrode structure and the catalyst membrane 5 in parallel arrangement; and the outside of the purification system is provided with a transformer 3 and a ballast 7 which are connected with two electrodes of the electrode structure and the ultraviolet lamp. The system combines and applies the nanometer photocatalytic technology, the low-temperature plasma technology and the active carbon adsorption technology into the vehicle air purification system; and the synergistic action of three kinds of technology can overcome respective limitation so as to achieve the effect of removing pollutants at high efficiency.

Description

technical field [0001] The invention belongs to the field of environmental protection, in particular to an air purification system used in the interior of a car. Background technique [0002] From the production to the use of vehicles, a series of processes are accompanied by the generation of pollutants. The production process mainly has the following methods: 1) When the vehicle is produced, a large amount of plastic products and adhesives are used for the interior parts of the vehicle. , its main components include formaldehyde, benzene, xylene, acetone, etc., which are the chief culprits of environmental pollution in the car; 2) After the engine has been running for a long time, the heat generated by it will increase the volatilization of pollutants in the car; If the air conditioner is not cleaned and maintained for a long time, a large amount of dirt will adhere to the inside, and the harmful substances such as amine, nicotine, and bacteria produced will permeate the s...

AI Technical Summary

Problems solved by technology

However, since the photocatalytic reaction is a surface reaction, whether low-concentration pollutants can fully contact the surface of the catalyst, and whether the photons emitted by the light source can excite the catalyst to generate more electrons and holes , are the main issues affecting the efficiency of photocatalytic air purifiers

[0004] (2) Activated carbon is an important adsorbent for removing polluted gases by physical methods. It has a large specific surface and has a strong adsorption effect on harmful gases contained in polluted gases. However, due to physical adsorption, it only plays a role in pollution. The transfer of pollutants does not reach the oxidative decomposition of polluted gases, so after a period of use, there will be adsorption saturation, and the filter element needs to be cleaned or replaced regularly

[0006] Due to the limitations of various technologies, there is currently no effective means to achieve the purpose of efficiently removing pollutants
