Purifying medium replaceable air purifier filter core which is used for removing formaldehyde

Abstract

The invention discloses a purifying medium replaceable air purifier filter core which is used for removing formaldehyde. The purifying medium replaceable air purifier filter core can be used in different places, and is especially suitable to be used for removing formaldehyde in newly decorated rooms or vehicles. The purifying medium replaceable air purifier filter core is divided into, in the filter core air flowing direction and based on functions, a filter layer, a decomposition layer, and an adsorption layer successively; is composed of a filter screen, and adsorption mediums such as alumina spheres loaded with oxidizing catalysts such as potassium permanganate, and high iodine value active carbon; and is used for interception of particle matters, decomposition of gaseous state pollutants, and adsorption of gaseous state pollutants which are not decomposed by the decomposition layer or other decomposition products; the decomposition layer and the adsorption layer are provided with material change openings, so that it is convenient for replacing of devitalized purifying mediums such as the oxidizing catalysts and adsorption mediums in the filter core. The purifying medium replaceable air purifier filter core can be used for filtering and removing particle pollutants, and decomposition and adsorption of gaseous state pollutants such as formaldehyde, benzene, and toluene; the using end point can be determined conveniently, the internal purifying mediums can be replaced conveniently, the using cost is reduced greatly, the purifying effect is enhanced, and filter core recycling is realized.

Description

technical field [0001] The invention belongs to the field of air purifier filter element production. It specifically relates to an air that can filter particulate pollutants, decompose and adsorb gaseous pollutants, and can indicate the use status, facilitate disassembly and assembly, facilitate replacement of purification media, and be reusable, greatly enhance the purification effect and reduce the use cost. Purifier filter. Background technique [0002] With the enhancement of social awareness of environmental protection, the problem of air pollution has become more and more important, especially the excessive formaldehyde, benzene, toluene and other benzene series substances caused by decoration (decoration) are the main reasons for indoor and car air pollution. Since the release of formaldehyde, benzene, toluene, etc. is long-term and slow, for example, the release cycle of formaldehyde is as long as 3-15 years, there is still a lack of effective treatment to solve ind...

AI Technical Summary

Problems solved by technology

However, the adsorption of the adsorption medium can only temporarily capture but cannot decompose the adsorbed gaseous pollutants. After the room temperature rises or the adsorption reaches saturation, the gaseous pollutants will be re-released to form secondary pollution, especially in newly renovated rooms. The concentration of gaseous pollutants is high. Depending on the amount of adsorption medium filled in different filter elements, the filter element will be saturated within a few to hundreds of hours and lose its purification ability.

[0004] The current air purifier filter elements are all formed in one piece, and the internal adsorption medium cannot be replaced, and the user cannot judge whether the internal adsorption medium of the filter element still has adsorption capacity. The user can only discard the filter element regularly and purchase a new filter element. The failure is fast, and the end of use cannot be effectively determined, resulting in high cost of use of the current air purifier, poor purification effect on gaseous pollutants, and discarded filter elements form new solid waste, resulting in waste of resources
