Abstract

The invention discloses a device and a method for purifying air by using low-temperature plasma activated water. The device comprises a low-temperature plasma generating device and an activated wateratomizing device. The low-temperature plasma generating device comprises a power supply, an insulating container and a plasma generating mechanism arranged in the insulating container. The plasma generation mechanism comprises an electrode array plate, a porous electrode column and a blocking dielectric tube. The electrode array plate comprises a connecting plate and an electrode column array group which is arranged at the bottom of the connecting plate and consists of high-voltage electrode columns. Through holes matched with the high-voltage electrode column are distributed in the porous electrode column, and a barrier dielectric pipe is arranged between the through holes and the high-voltage electrode column. At least two gas inlet holes for loading working gas are symmetrically formedin the upper part of the side wall of the insulating container wall. According to the device and the method, bacteria and fungi can be efficiently inactivated, the inactivation effect on specific species of fungi is remarkable, and most fungi in the air can be efficiently killed within 30 minutes (> 98.5%).

Description

Technical field [0001] The invention relates to the technical field of low-temperature plasma, in particular to a device and method for purifying air by using low-temperature plasma to activate water. Background technique [0002] At present, air disinfection often uses ultraviolet radiation and ozone fumigation. Ultraviolet radiation requires that the disinfected part be fully exposed to ultraviolet rays to achieve disinfection. When used for air disinfection, it requires a suitable temperature of 20°C to 40°C and a relative humidity of less than 80%. , Otherwise the sterilization effect is not good. Ozone fumigation and disinfection of air must be carried out indoors without people, and wait at least 30 minutes after disinfection before entering. [0003] The application of low-temperature plasma in the field of air disinfection and sterilization has just started, showing great potential. There have been related studies at home and abroad that directly expose microbial aerosols...
