Embodiment Construction

[0018] The passage of air entering the equipment is from the bottom to the top, and enters the electrode reaction layer after preliminary filtration through the bottom air inlet 101. The dust adsorbed on the electrode group 201 falls off and is collected in the cleaning box 102 for regular cleaning.

[0019] The electrode reaction layer is composed of multiple sets of electrode groups 201. Each electrode group 201 is composed of multi-layer needle-plate electrodes. The needle points of the positive and negative electrodes are arranged alternately. Electrode discharge produces a large amount of plasma. These high-energy particles can attract surrounding pollutant particles to form heavy ions. PM2.5 particles increase in size and charge, and move to the other end of the electrode to settle down under the action of a strong electric field. During the discharge, active groups such as hydroxyl radicals and ozone will be formed to decompose VOCs to a certain extent. The streamer dis...

Abstract

The invention relates to an indoor air processing technology and device. By means of the indoor air processing technology and device, PM2.5 particles, VOCs pollutant and germs in indoor air can be effectively removed. The indoor air processing device discharges to form a highfield to capture the PM2.5 particles, hydroxyl free radical and ozone are produced to decompose VOCs and play a disinfection role, the produced ultraviolet light plays a sterilization and disinfection role, the photocatalyst is activated to produce an electron hole, and the VOCs is oxidized and decomposed. A safety catalyst in the outlet of a reactor converts the ozone and NOX exceeding the standard into oxygen and nitrate. An ultrasonic nebulizer atomizes water or nontoxic organic matter absorbent and then enables the water or the nontoxic organic matter absorbent to be mixed with air, and the mixed gas is inflated into a filter filled with a modified tourmaline filter material. The indoor air processing device has the advantages that operation cost is low, the processing effect is good, secondary pollution cannot be caused, noise is low, and using is safe and reliable.

Description

technical field [0001] The invention relates to an indoor air treatment process and equipment, which mainly play the role of removing indoor PM2.5 particles, VOCs pollutants and killing germs. It belongs to the field of air pollution control. Background technique [0002] With the increasing pollution of the atmospheric environment and the increasing frequency of haze weather, the problem of indoor air pollution has become more and more serious. The current indoor pollution not only includes traditional dust PM10 and volatile organic compound VOCs such as formaldehyde and benzene emitted by decoration materials, but also a large number of PM2.5 particles and NOx. PM2.5 refers to particulate matter with a diameter of ≤2.5 microns in the atmosphere, also known as particulate matter that can enter the lungs, which has a great impact on air quality and visibility. PM2.5 poses a serious threat to human health due to its small particle size, large specific surface area, easy att...
