Abstract

The utility model discloses a compound filter screen of graphite alkene, it externally encapsulates frame (5) internal fixation has filter screen body (1), filter screen body (1) primary filter layer (2), with compound filter layer (3) of graphene film's HEPA and graphite alkene active carbon compound filter layer (4) be formed by stacking in proper order. Compound filter layer of HEPA and the compound filter layer of graphite alkene active carbon with graphene film make up the filter screen body of formation, and its purifying effect exceedes conventional filter screen far away. This filter screen has adopted compound filter layer of HEPA and the compound filter layer of graphite alkene active carbon with graphene film, consequently very big promotion the specific surface and the adsorption effect of filter screen body, can more effectively get rid of and filter noxious material, its purifying effect is far away above conventional filter screen.

Description

A kind of Graphene composite filter net
Technical field
The utility model belongs to air purification field, especially a kind of Graphene composite filter net.
Background technology
Along with expanding economy, present environmental pollution is day by day serious, and haze weather occurs again and again, is in quick-fried table status for a long time, and the air outside outdoor and car all exists serious pollution problem, is also a pollution space that can not be ignored in indoor and car simultaneously.The harmful substances such as the PM2.5 in haze are serious has jeopardized the healthy of people, and breathing clean air becomes a kind of demand urgently to be resolved hurrily.Existing air purifier, generally adopts the conventional filtration net of primary filter+HEPA+ active carbon, adsorbs, pollutant in filtered air, reaches the effect purified air.There is the slower weak point of specific area deficiency, adsorption rate in conventional filtration net, have impact on the adsorption effect of screen pack.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of Graphene composite filter net of advantages of good adsorption effect.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: it has screen pack body at outer enclosure frame internal fixtion, and described screen pack body is by primary filter layer, be formed by stacking successively with the HEPA composite filter of graphene film and Graphene active carbon composite filter.
HEPA composite filter with graphene film described in the utility model is composited by HEPA folded filter paper and the graphene film that is positioned at its both sides.
Graphene active carbon composite filter described in the utility model is composited by the honeycomb grid being filled with Graphene active carbon compound and the screen cloth that is positioned at its both sides.
Primary filter layer described in the utility model is cotton fiber filter course.
Outer enclosure frame material described in the utility model is EVA and/or paperboard.
The beneficial effect adopting technique scheme to produce is: Graphene is as the new material across the epoch, the specific area that its two dimensional surface crystal structure tool is very large, can as adsorbent of good performance, pollutant has adsorption dynamics adsorption kinetics faster on Graphene, its cavernous structure makes pollutant have higher diffusion rate, and directly causes the higher rate of adsorption.Therefore, formed by combining with the HEPA composite filter of graphene film and Graphene active carbon composite filter screen pack body, its clean-up effect is considerably beyond conventional filtration net.
The utility model have employed HEPA composite filter with graphene film and Graphene active carbon composite filter, therefore specific area and the adsorption effect of screen pack body is improved greatly, can more effective removal and filtering poisonous material, its clean-up effect is considerably beyond conventional filtration net.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
