Microenvironment air purification device

Abstract

The invention discloses a microenvironment air purification device, and belongs to the field of air purification. The microenvironment air purification device comprises a water curtain washing tank, wherein each of cross sections of the upper and lower parts of the water curtain washing tank is smaller than the cross section of the middle, openings are formed in upper and lower ends of the water curtain washing tank, and a negative pressure generation device is connected to the upper end opening of the water curtain washing tank; and the microenvironment air purification device further comprises a water tank, the water curtain washing tank is vertically located in the water tank, and a water pump is further arranged in the water tank and corresponds to the lower end opening of the water curtain washing tank. The water curtain washing tank with a special structure is used for multi-level water curtain purification on air entering a microenvironment, the air purification effect is better than that of the other purification equipment, the PM (particulate matters) 2.5 purification rate can reach higher than 57%, the PM 10 purification rate can reach higher than 56%, further, the structure is simple, the use is convenient, a special filter screen is not needed, equipment is not required to be replaced frequently, the operation cost is low, and the microenvironment air purification device is suitable for large popularization and application to environments such as a house, an office, a laboratory, a hospital and the like.

Description

technical field [0001] The invention relates to the field of air purification, in particular to a micro-environment air purification device. Background technique [0002] With the development of industrial economy, my country's air pollution is becoming more and more serious. Regional atmospheric environmental problems characterized by inhalable particulate matter (PM10) and fine particulate matter (PM2.5) are becoming more and more serious, harming the health of the people and affecting social harmony and stability. On the other hand, people's requirements for living and living environment are getting higher and higher. Many ordinary houses and factory operating rooms have installed fresh air systems to improve the air quality of micro-environments such as family homes and factory operating rooms. [0003] At present, for the air purification of micro-environment, the air is often not purified, and the polluted air is directly input into the micro-environment, or the princ...

AI Technical Summary

Problems solved by technology

[0003] At present, for the air purification of the micro-environment, the air is often not purified, and the polluted air is directly input into the micro-environment, or the principles of filtration, electrostatic dust removal, and activated carbon adsorption are used to purify the air. These treatments have high operating costs and poor purification effects.

For example, although the filter is used to filter, although it can partially reduce dust (PM2.5, PM10, etc.), once the filter is saturated, it needs to be replaced. The most important thing is that the filtering effect is poor, and the effect of reducing dust is very limited.
