Wet dust removal air purification system

Abstract

The invention discloses an air purification system adopting wet dust removal. The air purification system comprises an air return channel, an electric induction device, a spray device, an air inlet filter unit and an electrostatic dust removal device, wherein the electric induction device is arranged on the indoor top, the inlet end of the electric induction device communicates with the air return channel, and a high-voltage negative power supply is arranged in the electric induction device; the inlet end of the spray device communicates with the outlet end of the electric induction device, and an air cleaning agent is arranged in the spray device; the outlet end of the air inlet filter unit is arranged on one side of the outlet end of the spray device, and the inlet end of the air inlet filter unit communicates with an air inlet of an air conditioning system; and the inlet end of the electrostatic dust removal device is arranged on the other side of the outlet end of the spray device, and the outlet end of the electrostatic dust removal device communicates with the indoor top space. According to the air purification system, the technical problems of poor dust removal effect of the air purification system and difficulty in increasing the quality of indoor air are solved.

Description

technical field [0001] The present invention relates to an air purification system, more specifically, the present invention relates to a wet dust removal air purification system. Background technique [0002] In recent years, every autumn and winter, especially after winter, the central and eastern regions of China will encounter smog from time to time, and there is a trend of normalization of smog. Some environmental protection experts have analyzed that smog is likely to replace smoking as the number one "killer" of lung cancer. Among them, Beijing-Tianjin-Hebei, the Yangtze River Delta, Chengdu-Chongqing, and the Central Plains are the most polluted in the world, and the annual average concentration of PM2.5 has exceeded 70μg / m 3 , more than 2 times higher than the national standard and more than 7 times higher than the WHO guidance value. [0003] The smog and dust in the air, coupled with the environmental pollution caused by interior decoration, has become a social ...

Problems solved by technology

[0007] Another object of the present invention is to provide a wet dust removal air purification system. An electric induction device and a spray device are respectively arranged at both ends of the indoor top. After the dust in the indoor return air is charged in the electric induction device, it flows into the In the spraying device, it will be condensed and combined with the dry mist generated by water to form large-grained dust, wherein the outlet ends of the two spraying devices are set opposite to each other, and the condensed large-grained dust will collide with the air and combine to form larger-grained dust At the same time, the outlet end of the air inlet filter unit is connected to the collision area, and an upward blowing air blowing device is installed at the bottom of the collision area, and the return air and fresh air are further collided and mixed, and then sent to the electrostatic precipitator In the device, small particles of dust are effectively condensed and formed into larger particles of dust, which are effectively absorbed by the electrostatic precipitator. This invention solves the technical problems of poor dust removal effect of the air purification system and difficult improvement of indoor air quality.
