Method for coating ozone catalytic decomposition material on electrostatic outdoor fresh air or indoor air purified dust collection pole plate

Abstract

The invention discloses a method for coating an ozone catalytic decomposition material on an electrostatic outdoor fresh air or indoor air purified dust collection pole plate, and belongs to the technical field of indoor air purification. According to the method, the surface of a pre-treated pole plate is coated with ozone catalytic decomposition material slurry, pole plate roasting treatment is carried out, and the pole plate loaded with the ozone catalytic decomposition material is obtained. The method is applied to the pole plate with the narrow electrode spacing of an electrostatic dust removal device, dust-contained air flow can make sufficient contact with the pole plate, the ozone making contact with the pole plate can be efficiently removed under the room condition, the ozone catalytic decomposition reaction condition is moderate, no secondary pollution exists, and no safety hidden dangers exist. The method is simple and easy to implement, the production cost is low, the methodis applied to coat the n ozone catalytic decomposition material on the surface of the pole plate, and under the condition that the environment temperature of the pole plate ranges from 5 DEG C to 40DEG C, and the relative humidity ranges from 10% to 90%, the ozone removal rate can reach above 90%.

Description

technical field [0001] The invention belongs to the technical field of indoor air purification. Specifically, it relates to a method for coating an ozone catalytic decomposition material on a dust-collecting pole plate for electrostatic outdoor fresh air or indoor air purification, so as to remove ozone generated during the high-voltage discharge process of electrostatic dust removal. Background technique [0002] Indoor space is the place where people stay the longest, and the quality of indoor air is related to everyone's physical and mental health. Indoor air purifiers can effectively remove indoor air pollutants, improve indoor air quality, and create a healthy and comfortable indoor environment, so they are favored by contemporary people. Affected by atmospheric smog, particulate matter has become the most important indoor air pollutant. The main methods of purifying particulate matter in the air are fiber filtration and electrostatic dust collection. Fiber filtration...
