Bubbling type water washing air purifier

Abstract

The invention discloses a bubbling type water washing air purifier, and relates to the field of air purification. Indoor air is fed into a bubbling pipe type air purification pipe containing a surfactant through an air blower or a booster pump, water enters the air purification pipe from the top in a spraying manner, then air flow from bottom to top makes full contact with and absorbs water flow from top to bottom, the water finally flows into a water storage tank below a machine body, and the process is repeated to form water recycling. Toxic and harmful chemical substances, dust particles and bacterial microorganisms in the air are adsorbed, filtered and removed, and the treated purified air is discharged from a top air outlet. According to the purifier, sieve pores are continuously washed at a relatively high flow speed, scaling and filth blockage are not easy to generate, the purifier can be repeatedly used, a very good water-saving effect is achieved, the purifier can continuously work for a long time by adding water once, the removal rate of harmful substances such as formaldehyde, benzene series and radon in the air reaches up to 97% or above, and the concentration of the harmful substances in the purified air is 0.02 mg / m<3> or below.

Description

technical field [0001] The invention belongs to the technical field of air purification, and in particular relates to a bubble tube type air purification device. Background technique [0002] Indoor air pollution is an "invisible killer" that endangers human health, and it is also an environmental issue of common concern throughout the world. In my country, with the acceleration of urbanization, the health problems caused by indoor air pollution are becoming more and more prominent. The main sources are decoration, kitchen fume, smoking, human body and domestic garbage. Indoor air pollution has caused great harm to human health. , the prevention and control of indoor air pollution has become one of the special tasks of the Healthy China Action. The selection of air purifiers is currently an internationally recognized important method to improve indoor air quality. With the enhancement of health awareness and the improvement of living standards of Chinese residents, indoor ai...

Problems solved by technology

The problems they have are: the solid phase adsorption effect is not ideal; the purification effect will decrease significantly with the extension of use time, and the filter screen needs to be replaced regularly; the follow-up cost is high

[0005] Chinese patent CN211953058U discloses an indoor air humidifier and purifier, comprising a top cover, a humidifier shell and a purification box, characterized in that the fixing groove and filter plate are provided with jacks, and the fixing groove and filter plate The plates are detachably connected by pins, but the spray method usually has a small gas-liquid contact area and short contact time, so the purification efficiency in one pass is not high, and it is often used in combination with other technologies

However, the small-hole sieve plate is easy to block, and is not suitable for handling dirty, viscous and solid-particle feed liquid; the large-hole sieve plate is easy to leak liquid, requiring high operating pressure and low mass transfer efficiency.

The sieve plate tower takes into account the processing throughput, purification performance and energy consumption, but its structure is complex, the operation flexibility is small, and the safety requirements are high.
