Problems solved by technology

However, traditional adsorption materials have limited adsorption capacity and short service life. In actual use, the adsorption materials need to be replaced frequently, which limits the use of traditional adsorption purifiers.
[0005] Therefore, the current indoor air purification technology still needs to be improved.

Embodiment

[0057] Under the condition of 1m / s head-on wind speed, the first-pass efficiency of toluene with an inlet concentration of 1ppm can reach 93.5%, and its air resistance is less than 5Pa. The air purification module has a good purification effect on indoor pollutants, and has low wind resistance, which can effectively save fan energy consumption. The specific process of its purification-regeneration cycle test is: real-time monitoring of the concentration of pollutants before and after the purification module; The regeneration temperature is controlled at 80°C for 5 minutes and cooled for 5 minutes; then switch to the purification mode. After 5 purification-regeneration cycles, the first-pass efficiency of toluene can still reach 91.3%, and it has good performance stability.

Abstract

The invention provides an air purification sheet and an air purification module. The air purification sheet comprises a base material sheet, a purification coating and a heating assembly, wherein thepurification coating is arranged on the outer surface of the base material sheet; the base material sheet comprises a first supporting sheet and a supporting sheet; the heating assembly is arranged between the first supporting sheet and the second supporting sheet. Thus, the air purification sheet is simple in structure, convenient to manufacture and low in wind drag. The heating assembly is arranged in the air purification sheet and can make the purification coating rapidly regenerate in situ. The service life of a purifying material is prolonged. The air purification sheet can be used for effectively purifying indoor gaseous pollutants for a long term.

Description

technical field [0001] The invention relates to the field of air purification, in particular to an air purification sheet and an air purification module. Background technique [0002] With the increase in the number of new buildings, more and more new decoration materials and chemical products are used in interior decoration, which will release excessive pollutants such as volatile organic compounds (VOCs) and formaldehyde, causing serious indoor pollution . [0003] Volatile organic compounds and formaldehyde may cause sensory stimulation to the human body, make the human body feel dry, irritate the eye mucous membrane, nasal mucous membrane, respiratory tract and skin, etc.; cause headache, fatigue, drowsiness and other discomfort. Pollutants such as alcohols, aromatic hydrocarbons and aldehydes can irritate the mucous membrane and upper respiratory tract; some volatile organic compounds such as benzene, tetrachloroethylene, trichloroethane, trichloroethylene and formalde...
