Abstract
The utility model discloses a basalt/polyimide fiber composite filter spunlaced felt which is characterized in that basalt/polyimide fiber composite fibrous layers are symmetrically bonded on the upper and the lower surfaces of a basalt base fabric by the high-pressure water flow jet process. The utility model has the advantages that the basalt base fabric provides a good strength for the spunlaced felt; the fibrous surface layers are made of a mixture of basalt and polyimide fibers P84; and owing to the special three-leaf structure of the polyimide fiber P84, most of the dust particles can be entrapped on the surfaces of the spunlaced felt, so as to reduce the resistance of the filter material and increase the service life of the filter material; and besides, both the basalt and the polyimide fiber P84 are high-temperature-resistant materials, so that the service temperature of the spunlaced felt ranges from 120 DEG C to 2600 DEG C and the instantaneous service temperature can reach 3000 DEG C.
Description
Technical field
The utility model relates to a kind of filtering material that is used for flue gas and treating flour dust, particularly a kind of basalt and polyimide fiber combined filtration water thorn felt.
Background technology
At present, higher in the flue-gas temperature of industries such as iron and steel, metallurgy, cement, electric power, chemical industry, pharmacy, and etchant gas content is bigger, common water thorn felt is difficult to satisfy its high-temperature particle thing to the calcination of filter bag and the corrosive gas destruction to filtrate.
The utility model content
Technical problem to be solved in the utility model is basalt and the polyimide fiber combined filtration water thorn felt that a kind of filtering accuracy height, long service life will be provided.
In order to solve above technical problem, the utility model provides a kind of basalt and polyimide fiber combined filtration water thorn felt, at the upper and lower surface of basalt base cloth, injects with High-Pressure Water symmetrically and pastes basalt and polyimide fiber composite fibre layer.
Described basalt base cloth is the fabric that a kind of basalt yarn adopts the plain weave weave to make.
Superior effect of the present utility model is: the basalt base cloth provides good intensity for water thorn felt, fibrous face layer adopts basalt and polyimide fiber P84 to mix, because the special trilobal cross structure of P84, make the most of dust of dust be trapped within the surface of water thorn felt, reduce the resistance of filtrate, improved the service life of filtrate; Basalt and P84 are high-temperature material simultaneously, and the serviceability temperature of this water thorn felt is 120～260
0C, moment serviceability temperature can reach 300
0C.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
The number in the figure explanation
1-basalt base cloth;
2-basalt and polyimide fiber composite fibre layer.
The specific embodiment
See also shown in the accompanying drawing, the utility model will be further described.
As shown in Figure 1, the utility model provides a kind of basalt and polyimide fiber combined filtration water thorn felt, at the upper and lower surface of basalt base cloth 1, injects with High-Pressure Water symmetrically and pastes basalt and polyimide fiber composite fibre layer 2.
Described basalt base cloth 1 is the fabric that a kind of basalt yarn adopts the plain weave weave to make.
The utility model is dropped into actual operating mode use, through implementing proof, continuous operation temperature of the present utility model is 120
0C～260
0C, moment serviceability temperature be 300
0C, brute force 〉=2000N/5 * 20 ㎝ radially, broadwise brute force 〉=2000N/5 * 20 ㎝, radial fragmentation percentage elongation≤25%, broadwise elongation at break≤25%, air permeability 2～6m
3/ m
2Min has improved 10% service life.
