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 ...

Embodiment approach 1

[0028] Such as figure 1 Shown is a schematic structural diagram of the air duct 1 and the purification unit 6 in the air purification system in the car. The cross section of the air duct 1 is rectangular, and the polluted gas is introduced into the interior of the purification unit 6 through the air-inducing fan 2. The structure of the purification unit 6 is: parallel arrangement 2 plasma electrode structures and the catalyst film 5, 2 to 4 ultraviolet lamps 4 are arranged between the 2 plasma electrode structures and the catalyst film 5, and the function of the transformer 3 is to convert the primary side voltage (the 12V DC power supply used by the car) ) into a high pressure that can excite the plasma structure to generate a high-energy plasma. At the same time, the ballast 7 can directly supply power to the ultraviolet lamp 4 through a 12V DC power supply; the transformer 3 and the ballast 7 are arranged outside the air duct 1 . After the polluted gas passes through the p...

Embodiment approach 2

[0032] Such as Figure 6 As shown, the specific process is similar to Embodiment 1, except that two purification units 6 are arranged in the air duct, and the two purification units 6 are arranged as three plasma electrode structures and two sets of ultraviolet lamps 4 are arranged between the catalyst membrane 5 .

Embodiment approach 3

[0034] Such as Figure 7 As shown, the specific process is similar to Embodiment 1, except that the two electrode structures in the purification unit 6 are opposite to the catalyst membrane 5 at a certain angle, forming a wedge-shaped surface and placed in the air duct to increase the pollution between the polluted gas 1 and the catalyst membrane. 8 contact area.

Abstract

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...
