Background

In the application fields requiring gas filtration, such as air filters, air cooling systems, emission purification systems, etc., the gas is often filtered by using filter materials such as coarse filter cotton, fiber filter paper, filter paper with a through cavity, activated carbon filters, brush filters, etc., but the life cycle of these filter materials is often short.

Taking an air cooling system of a Computed Tomography (CT) machine as an example, an air inlet of the CT machine is filtered by coarse filter cotton. The main components of the coarse filter cotton are polyester fiber (PET) and polypropylene fiber (PP), the coarse filter cotton needs to be replaced after being used for 1 to 2 months under the rated air flow using condition, the filter cotton is allowed to be cleaned for two times at most, and the filtering efficiency is reduced by about 15% after being cleaned once. If the dust concentration in the environment is larger, the life cycle of the filter cotton is also reduced.

In addition, at present, the above-mentioned filter materials are mostly unrecoverable, and are often disposed of by incineration, and generate a large amount of harmful substances such as carbon dioxide and formaldehyde, which cause air pollution.
