Method and device for purifying air and application of device

Abstract

The invention discloses a device for purifying air. The device comprises an air exchange device and a ventilation pipeline. Openings are formed in two ends of the ventilation pipeline, the air exchange device is arranged at the opening in one of the ends of the ventilation pipeline, the opening in the other end of the ventilation pipeline is open, the openings in the two ends of the ventilation pipeline keep in the air, and the middle of the ventilation pipeline is arranged in media at the temperatures different from the temperature of the air. The device for purifying the air has the advantages that the middle of the ventilation pipeline with the openings in the two ends is arranged in the media at the temperatures different from the temperature of the air, the air exchange device is arranged at the opening in the corresponding end of the ventilation pipeline, accordingly, the air around the openings in the two ends of the ventilation pipeline can flow through the media at the temperatures different from the temperature of the air, and moisture in the air can be condensed; impurities in the air can be adsorbed and dissolved in condensed water, and accordingly the air can be easily and conveniently purified.

Description

technical field [0001] The present invention relates to the technical field of air treatment. More specifically, the present invention relates to a method, device and application of air purification. Background technique [0002] Before the 1970s, there were 8 typical environmental pollution incidents in the world, 5 of which were air pollution incidents. Environmental pollution includes three states of gas, liquid and solid. The impact of air pollution on weather and climate is very significant. The main aspects of performance are reducing the amount of solar radiation reaching the ground, increasing atmospheric precipitation, acid rain, and increasing atmospheric temperature. There are two main categories of air pollutants, one is aerosol state pollutants, which mainly include dust, smoke droplets, fog, falling dust, floating dust, suspended matter, etc.; aerosol refers to solid particles, liquid particles or their Suspension in a gaseous medium; liquid droplets or soli...

AI Technical Summary

Problems solved by technology

[0003] When people control urban air pollution, they use spraying water mist into the air or using chemical substances to react with harmful gases to deal with air pollution, which will easily cause new pollution sources, dust will be brought into the air twice, and water resources will be wasted; The existing air handlers are only for the purification of indoor air. Because of the high cost of air purification, the application of filtration or condensation of water vapor in the air needs to collect and transport low-temperature refrigeration fluid, which requires a large amount of energy to collect and transport low-temperature refrigeration fluid. The equipment is complicated, the use is restricted by the fluid conditions, it is difficult to purify the outdoor air, and it is difficult for people to obtain a high-quality outdoor living environment, especially for places with serious air pollutants such as roads with many vehicles and dusty factory areas. Purification of outdoor air is urgently needed
