Description

Novel environment-friendly household high-efficiency filter

Technical Field

Background

Fine particulate matter, also known as PM2.5, refers to particulate matter in ambient air having an aerodynamic equivalent diameter of 2.5 microns or less. Compared with the thicker atmospheric particulate matters, the PM2.5 has small particle size, large area, strong activity, easy attachment of toxic and harmful substances (such as heavy metals, microorganisms and the like), long retention time in the atmosphere and long conveying distance, thereby having larger influence on human health and atmospheric environmental quality. At present, China is one of the most serious areas polluted by fine particulate matters in the world, PM2.5 becomes a focus problem of wide public attention, and the problem of solving the pollution of PM2.5 is imminent.

One important means of controlling the concentration of particulate matter in air is air filtration. At present, air filters of ventilation air-conditioning systems mainly comprise a filter material type air filter and a double-area type static filter.

The filtering material type air filter can be classified into coarse effect, medium effect, high effect and the like according to the filtering efficiency grade and the filtering resistance matched with the filtering efficiency grade. Generally, the higher the filtration efficiency, the greater the filtration resistance during operation. The mechanism of the filter material type filter for trapping the particulate matters comprises inertia, interception, diffusion, static electricity and other effects. Different trapping mechanisms correspond to the particles in different particle size ranges, wherein the electrostatic effect has a good trapping effect on the particles of 0.1-0.5 micrometer. Therefore, before the dust-containing air enters the filter material type filter, the particles in the air can be charged with static electricity, which is helpful for improving the filtering efficiency of the filter.

The double-zone electrostatic filter purifies and utilizes the ionization part to carry the same electric charge with the particulate matter in the air, and the particulate matter that carries the electric charge is caught or is adsorbed on the dust collecting plate after running dust collector to reach air-purifying's purpose, the product shortcoming is higher to technical requirement, improper control can produce air pollutants such as ozone, nitrogen oxide harmful to the human body, the product advantage is that running resistance is low, the working costs is few, the later maintenance expense is low, and can kill microorganisms such as the bacterium in the air.

Therefore, a scheme combining the two technologies is lacked at present, and if the action mechanisms of the electrostatic filter and the filter material type filter are combined, the air filter with better filtering performance and wider application range can be obtained.
