Heating carbon film-adsorption-catalysis composite air purification filter screen and application thereof

Abstract

The invention discloses a heating carbon film-adsorption-catalysis composite air purification filter screen and application thereof. The composite air purification filter screen consists of a substrate layer, a heating carbon film, an adsorption layer, a catalytic layer and a filter layer, wherein the substrate layer mainly plays a role in supporting and protecting; the adsorption layer is mainlyused for rapidly adsorbing harmful gas components; the catalytic layer is used for decomposing gaseous organic matters; the heating carbon film is used for heating the adsorption layer and the catalytic layer, so the adsorption layer is regenerated and the activity of the catalytic layer is improved; and the filtering layer is mainly used for intercepting particles. The composite filter screen disclosed by the invention has the function of simultaneously and efficiently removing gaseous pollutants and particulate matters and the functions of desorption regeneration and environmental low temperature resistance, and can heat air to a certain extent; the flexible substrate is adopted, so bending can be achieved; meanwhile, heating efficiency and the adaptability of a purification module are improved, so the composite air purification filter screen can be used for masks, air purifiers and fresh air systems.

Description

technical field [0001] The invention relates to an air purification device, in particular to an adsorption-catalysis composite air purification device, which is applied in the technical field of air purification. Background technique [0002] Air purification is one of the hottest topics today. Air purification refers to providing overall solutions for various indoor environmental problems such as sterilization and disinfection, dust and haze removal, removal of harmful decoration residues and peculiar smells, so as to improve living and office conditions and enhance physical and mental health. healthy. Air pollutants are usually divided into particulate matter, gaseous pollutants, and biological pollutants. The acquisition of clean air requires the removal of the above pollutants at the same time. Due to the different natures of the above pollutants, the removal methods are also different. For example, filtration and electrostatic dust removal are mainly used for particula...

AI Technical Summary

Problems solved by technology

However, most of the heating devices reported so far are for granular catalysts or honeycomb catalysts, and the heating methods used are mainly heating sheets and resistance wires, and their structural design is also limited by the dual constraints of catalysts and heating parts.

[0005] Through the above analysis, it is found that adding a heating part to the air purification module can improve the effect of adsorption technology and catalytic technology, but the current heating methods are still relatively limited, mainly heating sheets or heating wires, which restrict the design of the purification module to a certain extent, for example , the device is difficult to apply to masks, and the heat transfer efficiency of thermal radiation needs to be improved
