Vertical barrel plasma indoor air purifying device

Abstract

The invention relates to a vertical barrel plasma indoor air purifying device, comprising an earthing electrode and a discharge electrode; wherein, the earthing electrode is barrel-shaped and is connected with a power ground; the discharge electrode is baculiform, and the surface thereof is evenly provided with a plurality of discharge pricks; the discharge electrode is connected with an output end of a high-frequency power supply; the earthing electrode and the discharge electrode are arranged together by an insulated bracket; the earthing electrode can be made by a metal mesh; an insulated cylinder is arranged outside the metal mesh for fixing the metal mesh; the diameter of the mesh of the metal mesh can not be larger than 4% of that of the earthing electrode; the discharge electrode can be made by metal bars; the discharge pricks are welded on the lateral side of the metal bars; the discharge pricks can be in the shape of pyramid or cone or sawtooth, and are distributed on the discharge electrodes in a layering way; 3-6 discharge pricks are arranged in the same layer and the directions of the discharge pricks in adjacent layers are staggered. The invention features relatively simple structure, good ionization effect, the capacity of realizing relatively high purification effect, thus being mainly applied to purification of indoor air.

Description

technical field [0001] The invention relates to a vertical cylinder type plasma indoor air purification device. Background technique [0002] People spend at least half of their life indoors. Due to the effective indoor space and less exchange with outdoor space, the indoor environment itself not only has no natural purification ability, but also due to the popularity of indoor decoration and air conditioners As well as people's daily life, pollutants are continuously discharged into the indoor space, mainly harmful substances such as volatile organic compounds, solid suspended particles and aerosols, such as formaldehyde, toluene, xylene, benzene, amine, ammonia, etc., causing Indoor air pollution seriously endangers people's health. The main pollutants include formaldehyde and benzene series. Therefore, with the improvement of people's living standards and the aggravation of air pollution, the problem of indoor air pollution has become more and more widespread. focus on. ...

Problems solved by technology

[0003] In order to improve the air in the above-mentioned environment, people have adopted many methods to kill bacteria in the air and eliminate harmful substances to reduce air pollution. Medium-efficiency, high-efficiency (sub-high-efficiency) filters, etc., the filter material is mainly glass fiber, synthetic fiber, asbestos fiber and filter paper or filter cloth made of these fibers, in order to filter the dust in the air to purify the air, However, these porous filter materials will increase the resistance of air flow, and with the prolongation of use time, the filtering effect will decrease. If they are not replaced in time, it will aggravate air pollution and even produce secondary pollution; (2) Static electricity The dust removal method discharges the circulating air to charge the dust in the air, and then uses the dust collection device to collect the charged dust to achieve the purpose of purifying the air, but this method cannot kill the bacteria in the air, and It is inconvenient to set up and use; (3) the ultraviolet ray sterilization method
