with population migration and improvement of living environment of people, people pay more attention to indoor air quality. And volatile organic compounds such as formaldehyde, xylene and the like released by indoor decoration (covering places such as ordinary households, offices, artistic spaces and the like) and furniture and the like seriously exceed the national standard, so that the harm to human bodies cannot be ignored. At present, technologies such as activated carbon adsorption, strong oxidant (chlorine dioxide CN104941408A and ozone) oxidation, biological enzyme formaldehyde removal and the like are mostly adopted in the market, the biological enzyme can generally remove formaldehyde in a short period but can not continuously remove formaldehyde, the chlorine dioxide and the ozone used in the oxidation method are harmful to human bodies, and the generated organic byproducts are extremely toxic. In addition, the physical technology of negative ions, low-temperature plasma and the like is adopted to easily generate high-concentration ozone, thereby causing secondary harm to human bodies.

The invention content is as follows:

in order to solve the problems of the prior art, the invention aims to overcome the defects in the prior art and provide an air purification device which can degrade formaldehyde in indoor air in a multiple, high-efficiency and continuous manner.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides an air purification device, includes purifier casing, pre-filtration net, activated carbon adsorption layer, photocatalytic decomposition layer, methanal neutralizer releaser and fan, and pre-filtration net, activated carbon adsorption layer, photocatalytic decomposition layer, methanal neutralizer releaser set up in the purifier casing, and its characterized in that is installed on the purifier casing to the fan: the purifying device comprises a purifying device shell, a fan, a pre-filtering net, an active carbon adsorption layer, a photocatalytic decomposition layer and a formaldehyde neutralizer releaser, wherein the purifying device shell is a cylinder, the fan is arranged above the cylinder, and the pre-filtering net, the active carbon adsorption layer, the photocatalytic decomposition layer and the formaldehyde neutralizer releaser are sequentially arranged on the purifying device shell from top to bottom; the formaldehyde neutralizer releaser is a piece of sponge dipped with formaldehyde neutralizer; the cylinder body below the formaldehyde neutralizer releaser is an air outlet, hollow through holes are uniformly arranged on the cylinder body wall of the air outlet, air introduced by the fan is purified and filtered and then output from the hollow through holes, and the formaldehyde neutralizer in the sponge is slowly released along with wind to react with formaldehyde in the air; the technical scheme is further explained as follows: the photocatalytic decomposition layer is graphene aerogel loaded with photocatalyst, the pore diameter of the aerogel is 0.05-100 microns, and the photocatalyst material comprises nano titanium dioxide particles or nano bismuth vanadate particles; the technical scheme is further explained as follows: the pre-filtering net is made of gelatinized cotton, and the surface of the gelatinized cotton contains AV-990 cationic groups; the technical scheme is further explained as follows: the active carbon adsorption layer is an active carbon fiber module.

Compared with the prior art, the utility model, have following apparent advantage:

1. the utility model discloses the release rate of formaldehyde under the high temperature is taken into full account and is accelerated, and the formaldehyde in furniture, panel can not be released completely to adopt high temperature fumigation or hot-blast blowing off on the present market, and formaldehyde dehydrogenase spraying treatment once or several times can only degrade the formaldehyde of high temperature release in the air, can not last effective degradation to remaining low concentration formaldehyde in the panel of later stage. Therefore, the invention adopts the formaldehyde neutralizer for long-term storage and has sustained action on the slowly released formaldehyde.

2. The utility model fully considers the problem of secondary pollutants brought in the process of processing formaldehyde, so oxidants such as sodium bisulfite, urea, chlorine dioxide, ozone and the like and ammonium agents are not adopted.
