Composite type air purification filter element with multilayered structure

Abstract

The invention discloses a composite type air purification filter element with a multilayered structure. The composite type air purification filter element comprises a coarse filter layer used for removing large-particle contaminants in air, a metal / molecular sieve layer used for adsorbing and decomposing corrosive gas in air, an organic adsorption layer used for adsorbing and catalytically decomposing organic harmful gas in air, a particle adsorption layer used for adsorbing small-particle contaminants in air and a sterilizing layer used for removing bacteria, molds and other harmful microorganisms in air. The composite type air purification filter element with the multilayered structure can effectively adsorb and treat various harmful substances, solves the problems that a traditional air purification filter element is single in function, low in efficiency and prone to produce secondary pollution and has the advantages of being high in adsorption efficiency and adsorption speed, large in adsorption capacity, wide in treatment range, environmentally friendly, capable of treating harmful gas and the like, and the market application prospects are wide.

Description

technical field [0001] The invention relates to a composite air purification filter element, in particular to a composite air purification filter element with a multi-layer structure, which belongs to the field of air purification. Background technique [0002] In recent years, with the rapid development of modern industry, environmental pollution has become more and more serious, especially in China, where the economy is developing rapidly. Living in turbid air for a long time will cause great damage to the nervous system, respiratory system, and immune system of the human body, resulting in decreased immunity and related diseases. At the same time, with the continuous improvement of people's quality of life, while striving for comfort and ease in the living environment, it is also required to have the functions of health preservation and health care. [0003] At present, the main pollutants in the air include several aspects: one is inhalable particles, dust, smoke, polle...

AI Technical Summary

Problems solved by technology

Although it has improved the shortcomings of the secondary pollution of traditional filters to a certain extent, it cannot absorb acid gases in the air such as hydrogen sulfide, sulfur dioxide, and acid gases containing chloride ions, and it is also difficult for small particle pollutants smaller than 2.5 microns. Adsorption, and it cannot decompose the adsorbed organic gases such as formaldehyde
