Microporous bubbling air purifier

Abstract

The invention belongs to the technical field of environmental protection technology and household appliances. A microporous bubbling air purifier is provided with a deflector and a primary filter screen at an air inlet, and a microchannel fine-pore sieve plate and a water-absorbing and air-permeable layer are provided in an airflow channel. The air flows in from the air inlet, blows the liquid film on the surface of the primary filter, the liquid surface in the water receiving tray and the water-absorbing air-permeable layer for storing the absorbing liquid successively, entrains a large amount of liquid to form a gas-liquid mixture, and mainly passes through the screen in the form of fine air bubbles. The microchannel of the plate forms a bubbling layer above the sieve plate, which generates a large number of bubbles and continuously breaks and renews to achieve extremely high gas-liquid contact area and mass transfer efficiency. The invention comprehensively utilizes liquid droplets, liquid films and bubbles to realize gas-liquid contact and process intensification, can not only effectively remove liquid or solid pollutants, but also can absorb and remove gaseous pollutants, and has high purification efficiency. The invention has the advantages of compact structure, convenient use, small gas phase resistance and no need to replace consumables.

Description

Technical field [0001] The invention relates to a gas purification device, which belongs to the technical fields of environmental protection technology and household appliances, and can be applied to household or commercial air purifiers. Background technique [0002] The 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 life and needs to be replaced regularly, and the use cost is high; catalytic technology, plasma technology, and electrostatic technology have good purification effects for specific pollution sources, and their use i...

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.
