Problems solved by technology

Studies have shown that the main component of smog is aerosol, and the composition is relatively complex. The main components are particles of aluminosilicate, sulfur dioxide, and nitrogen oxides, especially some heavy metal particles such as lead and chromium. The size of these particles is mostly at the nanometer level. , the above-mentioned air purification equipment is difficult to purify

Abstract

An indoor air purification system and purification method based on wet filtration, including a three-layer liquid collection tank connected together and containing a treatment solution capable of purifying the air arranged sequentially from top to bottom, a filter screen is arranged on the top of the treatment solution, and a There is an air outlet on the top of the body, and a suction fan is installed at the bottom of the lowermost liquid collection tank, and a stop valve is provided at the bottom of each liquid collection tank. The gas inlets are connected, and the gas outlet of the stop valve leads the gas into the corresponding liquid collection tank. The invention has the advantages of simple processing, convenient liquid addition, easy disassembly and assembly, can maintain good sealing performance, can effectively improve the purification rate of indoor air, remove toxic gases, dust, heavy metal particles and organic particles in the air, and humidify the air at the same time. Kill harmful bacteria and viruses and maintain good indoor air quality.

Description

technical field [0001] The invention relates to the field of air purification, in particular to an indoor air purification system and purification method based on wet filtration. Background technique [0002] At present, air pollution has seriously endangered people's safety. Northern regions often suffer from smog in winter, and the demand for air purification systems has increased sharply. The air purifiers currently used mainly include filter air purifiers, photocatalytic air purifiers, plasma air purifiers, etc. Some of these purifiers can purify formaldehyde in the air to a certain extent, and some can absorb relatively high levels of formaldehyde in the air large solid particles. Studies have shown that the main component of smog is aerosol, and the composition is relatively complex. The main components are particles of aluminosilicate, sulfur dioxide, and nitrogen oxides, especially some heavy metal particles such as lead and chromium. The size of these particles is ...
