Continuous distribution type photocatalyst indoor air purification device

Abstract

The invention discloses a continuous distribution type photocatalyst indoor air purification device, and belongs to the technical field of photocatalyst air purification. A reactant feeding box with pushing mechanism is arranged at top of reaction cylinder. A pushing mechanism continuously guides the photocatalyst reactant in a storage box into the fiber fluff light touch reaction surface in the vertical repeated movement process, wherein the photocatalyst reactant is continuously coated on the rotating fiber fluff light touch reaction surface, the shortage of the photocatalyst reactant is avoided, the reaction area is enlarged, the reaction time is prolonged, and the reaction efficiency is improved. Meanwhile, in cooperation with a connecting structure of the spraying pipe and the dissolving diffusion ball, an external water source drives sodium peroxide powder in the dissolving diffusion ball to diffuse outwards, the sodium peroxide powder encounters water to generate sodium hydroxide and oxygen, an aqueous solution generates water vapor in a reactor with a certain temperature, and a medium for the photocatalytic reaction is formed from a large amount of water vapor and oxygen; therefore, some oil stains and dust particles mixed in the air are removed by the generated sodium hydroxide solution.

Description

technical field [0001] The invention relates to the technical field of photocatalyst air purification, more specifically, to a continuously distributed photocatalyst indoor air purification device. Background technique [0002] Since a certain amount of formaldehyde needs to be added to traditional paint products, formaldehyde can sterilize and prevent corrosion, and effectively prevent the paint from deteriorating and moldy. After the house decoration is completed, the paint will more or less release formaldehyde gas during the drying process. It will pose a great threat to human health. [0003] At present, the physical adsorption method is widely used in the market to remove formaldehyde. The commonly used adsorbents are activated carbon and diatom mud. When the temperature rises, the adsorbed formaldehyde will break away from the adsorbent, so the effect of physical adsorption on removing formaldehyde is not ideal. Chemical catalytic degradation of formaldehyde is reco...

Problems solved by technology

In the prior art, the photoreactive agent is generally directly coated on the furniture or fixtures. After the photoreactive agent has reacted, it is difficult to carry out the subsequent photoreaction. Molecules or oxygen are the medium. If only relying on water molecules and oxygen in the indoor air, the reaction will be slow and the function will be limited.
