Secondary charge dust removal air purification system

Abstract

The invention discloses a secondary charged dust removing air purification system. The secondary charged dust removing air purification system comprises a return air channel, an electric induction device, a charged dust collection device, an inlet air filter unit and an electrostatic dust removing device, wherein the electric induction device is arranged at the top of the interior of a room; the inlet end of the electric induction device communicates with the return air channel; the electric induction device is internally provided with a high-voltage negative power source; the inlet end of the charged dust collection device communicates with the outlet end of the electric induction device; direct current high voltages are connected to the upper side and the lower side of the charged dust collection device; the outlet end of the inlet air filter unit is arranged on one side of the outlet end of the charged dust collection device; the inlet end of the inlet air filter unit communicates with an air supply outlet of an air conditioning system; the inlet end of the electrostatic dust removing device is arranged on the other side of the outlet end of the charged dust collection device; and the outlet end of the electrostatic dust removing device communicates with a space at the top of the interior of the room. According to the secondary charged dust removing air purification system, the technical problem that fine dust in air cannot be effectively filtered is solved.

Description

technical field [0001] The invention relates to an air purification system, more specifically, the invention relates to a secondary charging 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 p...

[0007] Another object of the present invention is to provide a secondary charging dust removal air purification system, in which an electric induction device, a spray device and a charged dust collection device are respectively arranged at both ends of the indoor top, and the dust in the indoor return air is After the induction device is charged, it is passed into the spray device to condense and combine with the dry mist generated by water to form large particle dust, and then pass through the charged dust collection device, and the charged large particle dust passes through the charged dust collection device The electric field bias in the charged dust collection device is adsorbed on the dust collecting plate of the charged dust collection device, where the outlet ends of the two charged dust collection devices are set opposite to each other, and the large particles of dust air collected by the charged dust collection device do not collide At the same time, the outlet end of the air inlet filter unit is connected to the collision area, and an upward blowing device is installed at the bottom of the collision area, after the return air and fresh air are further collided and mixed, Sending it into the electrostatic precipitator, the small particles of dust are effectively condensed into larger particles of dust, which are effectively absorbed by the electrostatic precipitator. This invention solves the technical problem that the fine dust in the air cannot be effectively filtered out
