A large-scale high-efficiency air purification equipment for public places

Abstract

The invention provides large-size efficient air purification equipment for a public place. The large-size efficient air purification equipment comprises an air inlet with a flange, an air outlet, provided with a flange, of a connection short pipe, a shell and a draught fan located in the shell, a particle adsorption device and a pressurizing device, and a base, and further comprises a washing device of the particle adsorption device and an anaerobic acidulation degradation device located at the bottom of the shell, wherein the washing device is located at the top of the shell; one end of the air outlet of the connection short pipe is further connected with an air-liquid separator; the particle adsorption device comprises a cavity; a titanium pipe is arranged inside the cavity; the surface of the titanium pipe is of a honeycomb-shaped titanium dioxide nano structure; the titanium pipe forms a bent loop structure in the cavity; the diameter of the titanium pipe is 3mm-10mm; and the large-size efficient air purification equipment has a good pressure-bearing capability, a strong PM2.5 (Particulate Matter 2.5) adsorption capability, large dust accumulation and long service life, and can also realize degradation washing of the titanium pipe.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to a large-scale high-efficiency air purification equipment for public places, which is suitable for the purification of PM2.5 dust, nitrogen oxides, aldehydes and other gases in the air. Background technique [0002] PM2.5 refers to particulate matter in the ambient air with an aerodynamic equivalent diameter less than or equal to 2.5 microns. It can be suspended in the air for a long time, and the higher its concentration in the air, the more serious the air pollution. Although PM2.5 is only a small component of the earth's atmospheric composition, it has an important impact on air quality and visibility. Compared with coarser atmospheric particles, PM2.5 has small particle size, large area, strong activity, easy to attach toxic and harmful substances (such as heavy metals, microorganisms, etc.), and has a long residence time in the atmosphere and a long transportation d...

AI Technical Summary

Problems solved by technology

Plant leaves have a large surface area, which can absorb harmful gases and adsorb PM2.5. The advantage is that it can produce beneficial gases. The disadvantage is that the absorption efficiency is low, and some plants will produce harmful gases

At present, the advanced method in the world is medium adsorption, such as HEPA filter. This method can play a very high-efficiency filtering effect in the early stage of application, but as the use time increases, the amount of dust accumulated in the medium tends to be saturated. It will bring secondary pollution and a significant drop in filtering effect
