Wet process purification device and method for air

Abstract

The invention discloses a wet process purification device and method for air. The purification device comprises a controller and a water circulation channel and an air purification channel which are controlled by the controller; the water circulation channel comprises a cylindrical shell with an open upper end, the upper part of the shell is provided with a mesh vent hole, the bottom of the shellis provided with a water return tank having a sealed structure, and the middle of the shell is provided with a middle water storage container communicating with the water return tank; and the outer ring of the middle water storage container is provided with a water filter tank having an annular structure, a water spray filter net is arranged under the water filter tank, the air purification channel comprises an air pump and a gas discharging pipe, and gas outlets of the gas discharging pipe are arranged between the middle water storage container and the water spray filter net. According to thewet purification device for the air provided by the invention, circulating water flows through the filter net to realize air purification, a circulating water system is adopted to realize water cleaning treatment, long-term effective operation of the purification equipment is conveniently maintained, and the device has simple maintenance and low costs.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to a wet air purification device and method suitable for household use. Background technique [0002] With the increase of the city scale, the air pollution in the urban area is more and more serious, and the indoor air quality without purification treatment will be worse than the outdoor air quality, especially in the dry winter in the north. With the expansion of urban population and city scale, the market demand for household small-scale air purification equipment is strong. [0003] The main pollutants in the atmosphere include particulate matter, harmful gases (nitrogen oxides, sulfides) and microorganisms (viruses and bacteria). At present, there is no comprehensive household air purification system that can efficiently filter particulate matter, harmful gases, and microorganisms at the same time. Most of the existing household air purification equipment adopts a dry...
