Electrostatic fresh air purification device

Abstract

The invention provides an electrostatic fresh air purification device. The electrostatic fresh air purification device comprises a shell and a purification module arranged in the shell. An outdoor air inlet pipeline and an indoor air inlet pipeline are arranged on one side of the shell, a purified air outlet pipeline is arranged on the other side of the shell, and air of the outdoor air inlet pipeline and air of the indoor air inlet pipeline are purified through the purification module and then blown out through the purified air outlet pipeline. The purification module comprises a filtering net and a draught fan. The ratio of the cross sectional area of the outdoor air inlet pipeline to the cross sectional area of the indoor air inlet pipeline is (2-4):(6-8). By means of the technical scheme, PM2.5 is efficiently removed, the one-time purification efficiency reaches 90% or above, meanwhile, efficient sterilization and removing of gaseous pollutants such as formaldehyde, methylbenzene and TVOC are achieved, and global-function purification is achieved; fresh air is introduced, oxygen is increased, and the comfort degree is improved; and resistance is small, and energy consumption is low.

Description

technical field [0001] The invention belongs to the technical field of air purification, in particular to an electrostatic fresh air purification device. Background technique [0002] At present, there are mainly two types of fresh air and purification products on the market. One is the fresh air ventilation system, which uses a parallel replacement method to introduce outdoor air and exhaust indoor air. This type of system can only solve the problem of fresh air, and does not The quality improvement is not obvious; the other is the indoor circulating air purifier, which can only solve the problem of indoor air quality, and the lack of fresh air will cause indoor hypoxia. [0003] At present, the existing air purifiers and fresh air technologies are as follows: [0004] (1) Ordinary indoor circulating air purifier, through various filter materials (glass fiber, non-woven fabric, ordinary static electricity, photocatalyst, cold catalyst, activated carbon, etc.), through the ...

AI Technical Summary

Problems solved by technology

[0008] In view of the above technical problems, the present invention discloses an electrostatic fresh air purification device, which can comprehensively solve the problems of fresh air, PM2.5, bacterial viruses, formaldehyde, toluene, and VOC, realize full-function purification, and double improve the indoor air purification effect , at the same time, it can meet the basic fresh air demand, purify fresh air and indoor circulating air at the same time, form a whole-house purification, with small resistance and low energy consumption
