Problems solved by technology

However, the activated carbon filter type air purifier in the existing disclosed technology is mainly limited to the purification of physical air pollution of suspended matter, and the photocatalyst air purifier mainly relies on absorbing ultraviolet rays as energy to decompose formaldehyde, benzene and other decoration chemical pollution, which is affected by the use environment. Influenced by the amount of ultraviolet rays that can be absorbed in the medium, the purification efficiency fluctuates greatly

Embodiment Construction

[0024] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0025] A membrane separation air cleaner, comprising a wind pressure device, an air separation device, the air separation device includes a separation membrane with a membrane wall densely covered with micropores, the separation membrane has one layer or more than two layers, and the separation membrane has two layers In the above, the separation membranes are arranged in the order of the size of the micropores of the membrane wall, and the separation membrane with the largest micropores of the membrane wall is arranged at one end where the air enters the air separation device, and the wind pressure device and the air separation device are integrated or separated. When adopting separate arrangement, the wind pressure device and the air separation device are connected through pipelines or air ducts. This kind of design structure is simple, and...

Abstract

The separating film air purifier includes wind pressure device and air separator, and features the air separator with one layer or several layers of separating film possessing densely distributed micropores. The several layers of separating film are so arranged orderly in the mrcropore sizes, that the separating film with largest micropores in the air entering side. The present invention adopts separating film with selectively penetrating capacity as the separating medium, and under the action of the wind pressure device, gas with molecules smaller than the micropores passes through the film while gas with molecules larger than the micropores is intercepted, reaching the aim of separating gas. The present invention has simple structure, high contaminated air separating efficiency and capacity of control operation.

Description

technical field [0001] The invention relates to a membrane separation air purifier, in particular to an air purifier for purifying polluted air by using the separation membrane separation principle according to the physical properties of different gas molecule sizes in the air. Background technique [0002] Air pollution, especially indoor air pollution, has become one of the top ten killers affecting human health. The number of deaths caused by indoor air pollution in my country reaches 111,000 people every year. However, the activated carbon filter type air purifiers in the existing disclosed technology are mainly limited to the purification of physical air pollution of suspended matter, and the photocatalyst air purifiers mainly rely on absorbing ultraviolet rays as energy to decompose formaldehyde, benzene and other decoration chemical pollution, which is affected by the use environment. The impact of the amount of ultraviolet light that can be absorbed in the medium cau...
