A kind of indoor air purification device for office

Abstract

The invention provides an indoor air purification device for office use, comprising an air outlet upper cover, an octagonal main body and an air intake base, an air outlet is arranged near the center of the top of the air outlet upper cover, and a circle is arranged at the center of the bottom of the air inlet base. Shaped air inlet, the octagonal main body includes several aluminum alloy casing panels, reinforced transition pieces, a cavity, and an air purification module located in the cavity, the air purification module located in the cavity is made of honeycomb titanium dioxide on the surface Made of titanium tube with nanostructure, the titanium tube forms a curved loop structure inside the cavity, and a pressurizing device connected to the cavity of the octagonal body is arranged inside the air intake base, and the lower end of the intake base There are also base feet, which have good pressure resistance, strong PM2.5 adsorption capacity, large dust accumulation, and long service life.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to an indoor air purification device for offices, 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 distance. Therefore, it has a...

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

[0007] Chinese invention patent CN103990344A discloses a spray-type PM2.5 purification device based on titanium dioxide fluid. The device uses titanium dioxide fluid to adsorb PM2.5. The advantage is that the effect is good and antimony dioxide will turn yellow after long-term use, which can effectively prompt People change the fluid, but it still has the disadvantage of reducing the amount of dust and needs to be replaced regularly
