Multi-stage indoor formaldehyde removing device with sterilization effect

Abstract

The invention provides a multi-stage indoor formaldehyde removing device with sterilization effect. According to the invention, a high-pass filter screen, a water vapor removing layer, a carbon dioxide removing layer, a steel mesh and a formaldehyde removing layer are sequentially installed between an air inlet and an air outlet; the high-pass filter screen is used for filtering dust particles andPM2.5 particles; the water vapor removing layer is made of a silica gel or molecular sieve, and the silica gel or molecular sieve is grown on activated carbon cotton or high-pass fibers; the carbon dioxide removing layer employs a metal organic framework material growing on the activated carbon cotton or high-pass fibers; the steel mesh is sprayed with nanometer silver ions and is provided with aplurality of uniformly-distributed ultraviolet lamps; and the formaldehyde removing layer is a metal organic framework material growing on the activated carbon cotton or high-pass fibers, and the metal organic framework material is doped with a photocatalyst. The multi-stage indoor formaldehyde removing device of the invention can remove PM2.5, dust, water vapor and CO2 gas step by step, therebyefficiently removing formaldehyde and achieving sterilization effect at the same time.

Description

technical field [0001] The invention relates to an adsorbent structure for efficiently removing indoor formaldehyde, which is suitable for CO 2 Indoor spaces with a certain concentration of harmful gases such as formaldehyde and formaldehyde require high-efficiency purification. Background technique [0002] With the improvement of people's production and living standards, the reports of disease incidents caused by formaldehyde and other major polluting gases in house decoration are gradually increasing, and the indoor environmental pollution problem has been paid more and more attention by people. Especially formaldehyde, as a colorless and irritating gas, is one of the main components of indoor polluting gases. It is mainly concentrated in plywood, fiberboard, particle board and other artificial boards in living room decoration materials and furniture, as well as in various paints and coatings, and there are also formaldehyde residues in textiles. When the concentration ...

Problems solved by technology

Also only for formaldehyde gas, not for CO 2 and other harmful substances such as bacteria, and because other gases will participate in the competitive adsorption with formaldehyde, the actual adsorption effect of the above two cases on formaldehyde remains to be verified

[0004] It can be seen that there is currently
