Air purification device adopting plasma discharge combined with modified molecular sieve and using method thereof

Abstract

The invention discloses an air purification device adopting plasma discharge combined with a modified molecular sieve and a using method thereof. The device comprises a filter screen module, a plasma purification device, a humidification pressurization device and a detection display control module. A gas outlet of the filter screen module is connected with a gas inlet of the humidification pressurization device, another gas outlet is connected with a dry air inlet of the plasma purification device, and a gas outlet of the humidification pressurization device is connected with a wet air inlet of the plasma purification device. According to the method, air is filtered through the filter screen module to be respectively sent to the plasma purification device and the humidification pressurization device; the air enters a humidification water tank to undergo water atomization through an ultrasonic nebulizer and then is sent to a wet air leading-in pipe of the plasma purification device; and the air entering the plasma purification device is purified through corona discharge. According to the air purification device and the using method, the W type plasma purification device is adopted to be favorable for prolonging reaction time and solve the problem of squeal; dry and wet air separation is adopted to promote gas mixing, and the VOC pollutant clearance rate is high.

Description

technical field [0001] The invention belongs to the technical field of air purification, and in particular relates to an air purification device combined with plasma discharge and modified molecular sieve and a use method thereof. Background technique [0002] At present, my country's air pollution is still very serious, mainly manifested as soot pollution and factory exhaust gas. The concentration of total suspended particulate matter in the urban atmospheric environment generally exceeds the standard; sulfur dioxide pollution has been at a relatively high level; the total amount of motor vehicle exhaust pollutants has increased rapidly; nitrogen oxide pollution is increasing, and harmful substances include formaldehyde, benzene, ammonia, radioactive radon, etc. . With the deepening of industrialization and urbanization in my country, it is difficult to improve the ambient air quality in the short term. The concentration of PM2.5, PM10, formaldehyde, benzene, germs and o...
