Horizontal plasma and adsorption type indoor air purifier with spraying humidity adjusting function

Abstract

The invention relates to a horizontal plasma and adsorption type indoor air purifier with a spraying humidity adjusting function. The interior of a shell of the horizontal plasma and adsorption type indoor air purifier is sequentially divided into a spraying humidity adjusting chamber, a plasma purification chamber and an adsorption purification chamber from front to back. Spray pipes with a plurality of spray nozzles are arranged in the spraying humidity adjusting chamber. A water tank is arranged at the bottom of the spraying humidity adjusting chamber. The spray pipes are connected with an immersible pump in the water tank. The plasma purification chamber internally comprises a plurality of vertical panels which are parallel to one another and are arranged at equal intervals. A plurality of discharging rods are evenly distributed between the panels. An adsorptive material layer is arranged in the adsorption purification chamber and made of active carbon fibers with precious metal cold catalysts. An air outlet is formed in the rear end of the shell, and an air inlet is formed in the front portion of the shell. The horizontal plasma and adsorption type indoor air purifier is relatively simple and good in ionization effect, can achieve the great purification effect, and is mainly used for indoor air purification.

Description

technical field [0001] The invention relates to a horizontal spraying and humidity-regulating plasma and adsorption 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 limited 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, air conditioners, etc. 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
