Problems solved by technology

The adsorption method usually uses adsorbents such as activated carbon. Since the adsorbent is usually a non-polar surface, the adsorption capacity and adsorption effect are limited; although the ozone oxidation method can effectively remove formaldehyde, ozone can react with unsaturated hydrocarbons and nitrogen oxides. A large number of free radicals and other groups, new substances will cause secondary pollution of the indoor environment; photocatalytic oxidation requires light energy as the driving force, and its application is subject to certain restrictions

Description

technical field [0001] The invention relates to the field of air purifiers, in particular to an air purifier for efficiently removing formaldehyde. Background technique [0002] People spend 80% of their time indoors. Therefore, the quality of indoor air is closely related to human health. Formaldehyde is a major pollutant widely present in indoor air, especially in newly decorated rooms. Formaldehyde is toxic to multiple systems and organs of the human body, and is irritating and toxic to the nervous and respiratory systems of the human body. Exposure to a large amount of formaldehyde can also cause allergic rhinitis. In the past 20 years, the rapid development of my country's real estate development has driven the rapid development of the decorative materials industry and the interior decoration industry. Due to the rapid development, the quality of decoration materials and the quality of decoration teams are uneven, the indoor decoration pollution has seriously affected...
