Description

technical field [0001] The invention relates to a plasma and photocatalytic air purifier for horizontal spraying and humidity adjustment, 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 pol...

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

[0004] In addition, the existing indoor air purifiers are often only used to eliminate pollutants in the indoor air, and due to the limitation of indoor environmental conditions, the indoor air is often too dry most of the time, especially for the northern regions during the heating season, long-term Dryness not only makes people feel uncomfortable, but also brings about the increase of suspended particles and germs and viruses in the air, which affects people's quality of life and health
