Horizontal plasma and photocatalytic indoor air purifier

Abstract

The invention relates to a horizontal plasma and photocatalytic indoor air purifier, comprising a shell body; wherein, the shell body is internally provided with a plasma purifying chamber and a photocatalytic purifying chamber from front to back in turn; the plasma purifying chamber is provided with a plurality of vertical flat plates which are parallel to each other and evenly spaced; a plurality of discharge bars are evenly distributed among the flat plates, and the surface thereof is evenly provided with a plurality of discharge pricks; the vertical flat plate is connected with a negative pole of a power supply, while the discharge bar is connected with a positive pole of the power supply; the vertical flat plate and the discharge bar are arranged together by an insulated bracket; the inside of the photocatalytic purifying chamber is provided with a photocatalytic ultraviolet light, and the top part and / or the bottom part of the photocatalytic ultraviolet light is provided with multilayers of photocatalyst filters; the back end of the shell body is provided with an air outlet, while the front end thereof is provided with an air inlet. The invention features relatively simple structure, good ionization effect, the capacity of realizing relatively high purifying effect, thus being mainly applied to purification of indoor air.

Description

technical field [0001] The invention relates to a horizontal plasma and photocatalytic indoor air purifier, which belongs to the technical field of environmental protection. 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 ...

AI Technical Summary

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 utilizes ultraviolet rays to kill germs in the air, but it is powerless to the dust in the air, cannot purify the air, and is also difficult to be set and used in the central air-conditioning system; (4) Plasma purification method, through the strong electric field and gas discharge generated by the plasma generator, the water molecules and gas molecules in the air are ionized, and after a series of complex excitation, dissociation and ionization processes, .OH, . Free radicals such as H,.O, and pollutants in the air undergo a series of complex redox reactions, in which volatile organic molecules are decomposed, thereby achieving the purpose of air purification. These free radicals also have a strong inactivation of microorganisms It achieves the purpose of sterilization while eliminating organic pollution, but the structure of the existing plasma generator or plasma purification device is relatively complicated, and the density of the generated plasma is small, the air purification speed is slow, and the sterilization The purification effect is not ideal
