Problems solved by technology

However, neither physical adsorption nor chemisorption can achieve satisfactory results, because when the adsorption and desorption reach equilibrium, the adsorbent will fail or need to be regenerated.
Plasma technology has a certain purification efficiency for benzene series gas, but the purification process has two disadvantages: 1) benzene series are prone to plasma polymerization or trigger polymerization to form small particles, resulting in excessive particles; 2) plasma discharge is easy to produce O 3 , harmful by-products such as CO and nitrogen oxides, resulting in secondary pollution
This mechanism is due to the continuous consumption of Ag + , so the service life (durability) of the antibacterial agent depends on the silver content of the antibacterial material, and eventually the antibacterial performance will fail due to the depletion of silver.
So the exudation mechanism of Ag + Antimicrobial agents have problems in service life and economy, and cannot adapt to the economic strategy of sustainable development

Embodiment 1

[0034] The integrated system purifying device of the present invention includes three main parts, that is, normal-pressure low-temperature plasma, electrostatic dust removal part and catalyst part.

[0035] (i) Atmospheric pressure low-temperature plasma: Corona discharge with an extremely uneven electric field is used to generate plasma. One pole of the corona electrode is a double zigzag, star, linear or needle electrode, and the other pole is a flat electrode. The voltage is DC or pulse voltage of 1-20kV.

[0036] (ii) Part of the electrostatic precipitator: The electrostatic precipitator is a device that uses a high-voltage electric field to charge the particles, and separates and settles the particles from the airflow under the action of Coulomb force. The electrostatic precipitator can capture all fine dust and mist droplets, the particle size range of which is 0.01-100μm, and the dust removal efficiency of PM10 and PM2.5 can be as high as 99.9%. Dust, the resistance of...

Abstract

The present invention is a single-atom nano-composite catalyst air purifier that simultaneously removes formaldehyde, benzene series organic matter, carbon monoxide, ozone and high-efficiency antibacterial in a room (vehicle) by atmospheric pressure plasma and room temperature catalysis, and involves plasma, electrostatic dust removal, and environment Catalysis, environmental protection and air purification fields. It is characterized in that pollutants such as formaldehyde, benzene series organic matter, carbon monoxide, ozone, bacteria and germs in the air are effectively removed through low-temperature plasma, electrostatic dust removal and integrated catalyst integration technology, as shown in the figure. The present invention successfully utilizes plasma, electrostatic precipitator and room temperature catalyst technologies, successfully and efficiently removes multiple pollutants at the same time without secondary pollution, and overcomes the existing single technology in closed or semi-closed spaces such as rooms (vehicles) The application bottleneck in the field of air purification in China has an absolute leading position in the world.
