Wet air purification method and air purification apparatus

Abstract

The invention provides a wet air purification method which integratedly uses the three purification technologies of centrifugal purification, water spray purification and water film purification. A dynamic water film purifying process is used in the water film purification; i.e., a water film maintains moving with an included angle of the water film and an air flowing direction being 90 DEG and actively cuts air flow so as to increase probability and frequency of collision between air and the water film, so purifying efficiency is improved, and finally, miniaturization and high efficiency of a purification apparatus are realized. The wet air purification method is applicable to any apparatus carrying out gas purification. An air purification system is characterized by comprising a rotary cylindrical filter screen, a spray pipe, a cylindrical vessel and other necessary parts like a water pump and a blower fan. A household washable air purifier designed based on the wet air purification method comprises two parts, i.e., a freely separable water tank and a purification host machine, wherein the bottom of the purification host machine is provided with a water pump, the upper part of the water pump is connected with a spray pipe having an open pore, the exterior of the spray pipe is provided with a cylindrical metal filter screen assembly using the spray pipe as a rotating shaft, the filter screen assembly is disposed in a cylindrical purification chamber, the upper part of the purification chamber is connected with a centrifugal fan, and a control circuit is mounted on the upper part of the centrifugal fan.

Description

technical field [0001] The invention relates to an air purification method and air purification equipment, belonging to the technical field of air purification treatment. Background technique [0002] At present, there are many kinds of air purification products on the market, but the purification principles adopted are basically dry multi-layer filtration and adsorption methods (such as electrostatic adsorption, activated carbon adsorption, HEPA filtration, etc.), coupled with various catalytic and decomposition methods (such as photocatalyst). When this type of purifier is working, pollutants are directly accumulated on the filter device, which will affect the filtering effect, and it is easy to become a breeding body of bacteria and form secondary pollution. Simultaneously its filtering device generally can't be cleaned, needs to be replaced after using for a period of time, and it is inconvenient to use, and the use cost is high. [0003] The use of wet dust removal an...

Problems solved by technology

[0004] The purpose of the present invention is to solve the miniaturization and high-efficiency application problems of wet dust removal and purification technology, so that industrial dust removal and purification equipment can be miniaturized, and at the same time, the wet air purification method can be applied to household air purifier products, thereby completely solving the problem. The inconvenient treatment of pollutants in dry household air purifiers and the existence of secondary pollution problems have led to new expansions in the use of household air purification products, from dry purification to wet purification
