Abstract

The utility model provides a filter cloth structure with an electrostatic air filter. The filter cloth is composed of N (>/=2) layers of cloth; the first layer is a coarse fibre cloth layer; the rest layers are electrostatic fine fibre cloth layers. The filter cloth of the filter has the advantages of high electrostatic amount caused by friction, easy dust collection, difficult falling in the transmission, avoidance of secondary dust rising, difficult breakdown of large granule dust, good filtering effect and long service life.

Description

A kind of structure that contains the electrostatic air filter filter cloth

The utility model belongs to the air cleaner field, specifically is a kind of structure that contains the electrostatic air filter filter cloth.

At present, what the filter course of general air cleaner adopted all is the fibrage that polyester staple fiber forms after treatment, this fibrage in use exists a lot of deficiencies, the space is bigger between this fibrage fiber, not too even, big dust particle easily punctures fibrage, and the granule dust also sees through fibrage easily, this filter filter cloth is not strong to the absorption affinity of dust, the weak effect of filtration.

The purpose of this utility model provides a kind of electrostatic air filter filter cloth structure that contains, and this filter filter cloth adopts sandwich construction, and adopts the friction fiber cloth of super static easily, and the filter effect of filter is improved.

The filter cloth that the purpose of this utility model is achieved in that this filter is made up of N (〉=2) layer cloth, and employing contains the fibrage of static.

Concrete structure of the present utility model has: the structure of this filter cloth is 2 layers, and ground floor is the crude fibre bed of cloth, and the second layer contains the fine cloth bed of material of static.

Concrete structure of the present utility model also has, and the structure of the filter cloth of this filter is 3 layers, and ground floor is the crude fibre bed of cloth, and the second layer is the middle coarse cloth bed of material that contains static, and the 3rd layer for containing the fine cloth bed of material of high static.

The utility model is owing to the filter cloth to filter adopts sandwich construction, and employing contains the fibrage of static, the filter cloth of filter is had because of fricative static content height, difficult drop-off during easily seizure dust, and transmission is avoided reentrainment of dust, big dust particle also is difficult for puncturing simultaneously, its good filtration effect, long service life has high economic benefit and social benefit.

Below in conjunction with accompanying drawing the utility model is elaborated.

Accompanying drawing 1 is the of the present utility model one concrete structural representation of implementing side

Accompanying drawing 2 is the structural representation of another specific embodiment of the present utility model.

As shown in the figure: filter cloth of the present utility model is made up of N (〉=2) layer cloth, and this filter cloth structure shown in Figure 1 is 2 layers, and ground floor is a crude fibre bed of cloth 1, and the second layer is the fine cloth bed of material 2 that contains static.

This filter filter cloth structure shown in Figure 2 is 3 layers, and ground floor is a crude fibre bed of cloth 1, and the second layer is to contain 3, the three layers of the middle coarse cloth bed of materials of static for containing the fine cloth bed of material 2 of high static.

The utility model is in use because the wind speed of general air blast can both reach the meter per second above 1.5-3, make filter cloth produce static because of friction, easily catch grit, avoid dust to enter main frame, owing to adopt sandwich construction, the Dust Capacity that enters the crude fibre layer reduces, the granule dust is adsorbed, big dust particle weakens at thick layer medium velocity, finally by Electrostatic Absorption, can not puncture filter cloth; Simultaneously multilayer contain static fibrage when transmission under the effect of static, make the dust difficult drop-off, avoid reentrainment of dust.
