Method for removing indoor formaldehyde

Abstract

The invention relates to the field of indoor formaldehyde removal, in particular to a method for removing indoor formaldehyde. Firstly, through heating and humidifying, the indoor formaldehyde is released as much as possible, then by spraying a formaldehyde clearing agent and conducting multiple times of air blowing, formaldehyde is removed through ventilating, after indoor formaldehyde is removed, a formaldehyde inhibitor is sprayed to the place where formaldehyde is prone to being generated to seal formaldehyde, and release of follow-up formaldehyde is reduced.

Description

technical field [0001] The invention relates to the field of indoor formaldehyde removal, in particular to a method for indoor formaldehyde removal. Background technique [0002] Formaldehyde has been defined as carcinogenic and teratogenic substances by the World Health Organization. It is a recognized source of allergies and one of potential strong mutagenic substances. Nowadays, in interior decoration, decoration materials and furniture floors, adhesives often contain formaldehyde, long-term exposure to low-concentration formaldehyde can cause respiratory diseases, etc. Children and pregnant women are particularly sensitive to formaldehyde, which is extremely harmful and can cause neonatal Chromosomal abnormalities, leukemia, memory loss in adolescents, pregnancy syndrome, menstrual disorders and other diseases, even young people with strong bodies will suffer from dizziness, nausea and shortness of breath. Formaldehyde is the most important and most irritating source of...

Problems solved by technology

[0003] Formaldehyde mainly exists in decorative materials, furniture, and wooden floors. The binder is the main source of formaldehyde. As time goes by, the binder formed by compounding will undergo a reversible reaction and slowly release the raw material formaldehyde, resulting in indoor formaldehyde pollution. exceed the standard

At present, there are many ways to remove formaldehyde. Traditional physical methods include placing activated carbon and plants, and using their adsorption to remove formaldehyde. However, the effect of plant adsorption is negligible. Excessive concentration of formaldehyde may even cause plant death. Activated carbon adsorption has a slight effect , but needs to be replaced frequently, once the adsorption is saturated, it is easy to spit out formaldehyde, causing secondary pollution; using a new material photocatalyst to remove formaldehyde can effectively decompose formaldehyde, but the photocatalyst needs to work under ultraviolet light, and the indoor environment cannot receive so much ultraviolet light At the same time, the photocatalyst technology is still immature; the principle of installing an air purifier at home is to filter dust, PM2.5 and other particles in the air through an activated carbon filter, which cannot remove organic molecules such as formaldehyde. The purifier is an indoor cycle, and formaldehyde is always indoors, which can neither be absorbed nor discharged; there are also some commercially available formaldehyde cleaners sprayed to neutralize, oxidize or decompose formaldehyde through various reactions, but these methods are harmful to formaldehyde. The treatment is immediate, and the generation of formaldehyde is a slow release process, which cannot effectively remove formaldehyde for a long time

[0004] The patent with the application number CN201711472229.5 proposes a method for removing latent formaldehyde. Through multiple ventilations, combined with formaldehyde scavenger to remove formaldehyde in the room. Although this method can remove most of the residual formaldehyde in the room, it can only remove most of it temporarily. Formaldehyde, and the test of formaldehyde content is immediate, it can only show that the formaldehyde content is less after treatment, and it cannot guarantee that the indoor formaldehyde will always meet the standard in the future
