Air purification device based on low-temperature plasma technology

Abstract

The invention discloses an air purification device based on a low-temperature plasma technology, and belongs to the field of air purification. According to the the scheme of the air purification device based on the low-temperature plasma technology, a fan rotates after being powered on, and air forms circulating air flow through a circulating air inlet hole and an exhaust ring to enable a purification air duct to rotate, suspended substances in the air are prevented from adhering to the inner wall of the shell so that the air quality is improved; the cold catalyst layer performs catalytic reaction on harmful substances in the air at normal temperature to generate water and carbon dioxide, the suspended substances and the harmful substances are mixed with the water, the weight of the suspended substances and the harmful substances is increased, and the suspended substances and the harmful substances fall into the storage frame, air enters the purification air duct through the air inletholes along the flow guide grooves in the outer ends of the adsorption blades through purification of harmful substances and suspended solids by hydrogen peroxide, the cleaning plate expands when encountering water, abuts against the inner wall of the shell and limits rotation of the purification air duct, and water generated by reaction of the cold catalyst layer and harmful gas is prevented fromcirculating to the exterior of the shell.

Description

technical field [0001] The invention relates to the field of air purification, more specifically, to an air purification device based on low-temperature plasma technology. Background technique [0002] Air purification refers to providing overall solutions for various indoor environmental problems such as sterilization and disinfection, dust reduction and haze removal, removal of harmful decoration residues and peculiar smells, improving living and office conditions, and improving physical and mental health. Indoor environmental pollutants and pollution sources mainly include Radioactive gas, mold, particulate matter, decoration residue, second-hand smoke, etc. [0003] my country's air pollution has evolved from soot-type pollution in the last century to regional and complex air pollution, and has become the region with the most serious aerosol pollution in the world. At the end, the average annual concentration of PM2.5 has exceeded 70ug / m 3 , more than 2 times higher tha...

Problems solved by technology

[0005] At present, most of the purification devices filter harmful substances in the air, and cannot effectively sterilize and disinfect harmful gases. When replacing the filter element of the purification device, harmful gases will still cause secondary pollution
