A formaldehyde purification device and method for treating gas

Abstract

The invention relates to a formaldehyde purification device and a method for treating gas. The formaldehyde purification device includes an air pump and an assembled reaction bottle, and the assembled reaction bottle includes an aeration reaction bottle, a defoaming reaction bottle and an activated carbon adsorption bottle. A proteolytic formaldehyde adsorbent is housed in the aeration reaction bottle, a defoamer is housed in the defoaming reaction bottle, and granular activated carbon is housed in the activated carbon adsorption bottle; the aeration reaction bottle is equipped with a pH meter to monitor the The degree of saturation of the proteolytic formaldehyde adsorbent to adsorb formaldehyde. Use the formaldehyde purification device to suck the gas to be treated in a small space such as a wardrobe into the reaction bottle through an air pump, and after a series of treatments such as adsorbents in the bottle, the purpose of removing formaldehyde and other harmful gases is achieved. The pH meter is used to judge the saturation degree of the adsorbent , avoid empty consumption, have a good effect of removing formaldehyde, and are highly targeted and low in cost.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to a formaldehyde purification device and a gas processing method. Background technique [0002] Air purifiers can provide people with clean and safe air. Various purifiers have different purification principles and purification processes. There are many different technologies and media. The purification technologies commonly used in air purifiers on the market mainly include adsorption technology, high-efficiency filtration technology, catalysis, negative ion, plasma technology, etc. The commonly used materials mainly include activated carbon, synthetic fiber, photocatalyst, HEAP high-efficiency materials, etc. There are obvious differences in air purification efficiency and purification quality. According to relevant evaluation results, the technology of air purifiers to purify PM2.5 in the air is relatively mature, but its ability to remove formaldehyde is uneven, and p...

AI Technical Summary

Problems solved by technology

According to relevant evaluation results, the technology of air purifiers to purify PM2.5 in the air is relatively mature, but its ability to remove formaldehyde is mixed, and problems such as inflated prices and exaggerated efficacy are prominent.

[0003] And the current air purifiers are mainly designed for larger spaces, and some rooms themselves are not very polluted, mainly because the adhesives in the interior panels of some newly purchased furniture will continue to slowly release formaldehyde, which will cause air pollution in the cabinet. Cumulative and high-concentration pollution in local closed spaces such as drawers and drawers

If you directly purify the air in the whole room, not only will the polluted gas originally located in the cabinets and drawers permeate the whole room, increasing the processing capacity, but also the processing effect will be greatly reduced

If these local spaces are sprayed directly with aerosol, it will cause contamination to the objects in the cabinet
