preparation example Construction

[0032] Concrete, the preparation method of described loaded micronano-silver activated carbon, comprises the steps:

[0033] 1) Clean the activated carbon: dry the activated carbon after cleaning;

[0034] 2) Ammonia water impregnation modification: the activated carbon obtained in step 1) is impregnated in an ammonia solution, then taken out and dried;

[0035] 3) Loading micro-nano silver: immerse the activated carbon obtained in step 2) in a silver nitrate solution, then take it out and dry it to obtain the micro-nano silver-loaded activated carbon, and the silver loading of the micro-nano silver-loaded activated carbon is 0.0002-0.1wt %.

[0036] Wherein, the micro-nano silver is elemental silver.

[0037] The activated carbon is porous activated carbon and has good electrical conductivity and water absorption rate, and its electrical conductivity is 200-1000 S / m.

[0038] In the step 1), the main purpose of cleaning the activated carbon is to remove some ash and impuri...

Abstract

The invention provides a formaldehyde removal module. The formaldehyde removal module comprises a micro-nano silver loaded active carbon and a shell, the micro-nano silver loaded active carbon is placed in the shell, and the formaldehyde removal module has a long-acting formaldehyde removal effect. The invention furthers discloses an air purifying device containing the formaldehyde removal module, and an air purifier containing the formaldehyde removal module. The air purifying device and the air purifier respectively have the advantage in long-acting formaldehyde removal.

Description

technical field [0001] The invention belongs to the field of indoor air purification, and in particular relates to a formaldehyde removal module and an air purification device. Background technique [0002] Due to the rapid development of industrialization and the increase of automobiles, China has become the country with the fastest increase in air pollution in the world. Air pollution has seriously affected people's healthy life, indoor and outdoor pollution parallel, facing internal and external troubles. With the more modernization of production and lifestyle, more work and recreational and sports activities can be carried out indoors, and people spend more time indoors. According to statistics, urban residents spend an average of more than 80% of their time indoors every day, especially the elderly, young, sick, disabled and other frail groups with low body resistance and fewer opportunities for outdoor activities. The time is even as high as 93%+. The incidence of v...
