Air purifying system with loop-current cyclone dust removal

Abstract

The invention discloses an air purifying system with loop-current cyclone dust removal. The air purifying system comprises an inlet air filter set, a cyclone mixing device, a gas washing device, a first return air filter and a second return air filter, wherein the lower end of the inlet air filter set is provided with a top channel; the cyclone mixing device is arranged in a sandwich layer of an indoor side wall; the inlet end of the cyclone mixing device communicates with the upper end of the top channel; the outlet end of the cyclone mixing device communicates with the top channel; indoor return air treated by the cyclone mixing device is transmitted into the gas washing device; the first return air filter is arranged on the center of the indoor bottom; the first return air filter communicates with the air inlet of an air regulating system; the second return air filter is arranged at the two sides of the indoor bottom; the second return air filter is used for treating indoor air and directly transmitting the treated indoor air into the cyclone mixing device. The air purifying system solves the technical problem of great space usage and low treatment efficiency of the air purifying system.

Description

technical field [0001] The invention relates to an air purification system, more specifically, the invention relates to an air purification system for circulating cyclone dust removal. 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 so...
