Micro pore bubble type air purifier

Abstract

The invention belongs to the technical field of environment protection techniques and household appliances. According to a micro pore bubble type air purifier, a deflector and an elementary filter net are arranged at an air inlet; a micro channel fine pore sieve board and a water absorption permeable layer are arranged at an air flow channel; air flows in from the air inlet, blows the liquid membrane on the surface of the elementary filter net, the liquid surface in a drip tray and the water absorption permeable layer for storing absorbed liquid in sequence and carries a large amount of liquid to form a gas-liquid mixture; the mixture passes through the micro channel of the sieve board mainly in a micro air bubble form; a bubbling layer is formed above the sieve board; a large amount of bubbles continuously burst and update, so that extremely high gas-liquid contact area and mass transfer efficiency are realized. According to the micro pore bubble type air purifier, liquid drops, liquid membranes and bubbles are comprehensively used for gas-liquid contacting and process strengthening; not only are liquid or solid pollutants effectively removed, and also gas pollutants are absorbed; the air purifier has high purification efficiency, is compact in structure, convenient to use and small in gas phase resistance and needs no consumable replacement.

Description

technical field [0001] The invention relates to a gas purification device, which belongs to the technical field of environmental protection technology and household appliances, and can be applied to household or commercial air purifiers. Background technique [0002] An air purifier is a purification device that removes various solid and gaseous pollutants in the air. Commonly used air purification technologies include filtration technology, adsorption technology, absorption technology, plasma technology, negative ion technology, chemical catalysis, photocatalysis, electrostatic dust collection, Ozone technology, etc. Among these technologies, high-efficiency filtration technology and adsorption technology have stable performance, but the filter material has a short service life and needs to be replaced regularly, and the cost of use is high; catalytic technology, plasma technology, and electrostatic technology have better purification effects for specific pollution sources,...

AI Technical Summary

Problems solved by technology

Due to the limitations of noise, structure and other factors on the fan, the gas phase resistance requirement of household air purifiers is usually 100-200Pa, and it is difficult to enter the practical application when the pressure drop reaches 300-500Pa, and the higher pressure drop is basically impossible to implement.

In the bubbling purification technology, the gas needs to overcome the pressure of the liquid level when passing through the bubbling layer, and the gas phase resistance is very high, so it has not been successfully applied in household air purifiers.
