Abstract
The utility model discloses a composite filter felt structure which has a base fabric layer formed by a woven acrylic fiber, and the upper surface and the lower surface of the base fabric layer are symmetrically glued with mixed fiber layers. The mixed fiber layer is formed by blending terylene and the acrylic fiber. The composite filter felt structure uses composite terylene and the acrylic fiber, which makes the best of the two materials, has strengthened effect and makes up the disadvantages of a single fiber, so that the composite filter felt has the advantages of high strength, good hydrolysis resistance performance, good anti-oxidizability, good wear resistance performance, excellent filter effect, long service life, low cost, etc. The composite filter felt further has good anti-erosion ability to both organic and inorganic acids, so that the composite filter felt is suitable for dedusting management of high humidity flue gases under the condition of relatively low temperature requirement in cement industry, reducing the failure of filter bags ahead of schedule caused by hydrolysis, and prolonging the service life of the composite filter felt.
Description
Technical field
The utility model belongs to the technical field of normal temperature chemical fibre filtrate, refers to especially a kind of composite filter felt structure.
Background technology
At cement industry, it is high that the flue dust that the operating mode that some temperature requirements are lower produces has moisture, and dust viscosity is large, and the operating temperature characteristics such as between 65 ~ 120 ℃ often use normal temperature chemical fibre filtrate to carry out dust removal by filtration.In the prior art, dust removal by filtration mainly contains the chemical fibre filtrates such as terylene, polypropylene fibre, acrylic fiber with normal temperature chemical fibre filtrate, and these chemical fibre filtrates all exist weak point separately.Wherein, polyster fibre chemical fibre filtrate easily is hydrolyzed; especially under the condition of inorganic acid and organic acid existence, more easily be etched; the phenomenons such as filter bag hydrolysis inefficacy often can appear in actual condition is used; even cause filter bag damage; cause dust leakage, can't be applicable in the cement industry smoke harnessing to high-humidity gas fume under the lower operating mode of temperature requirement.
The utility model content
The purpose of this utility model provides a kind ofly has good resistance to organic and inorganic acid, to guarantee filter effect and the composite filter felt structure in service life.
In order to reach above-mentioned purpose, solution of the present utility model is:
A kind of composite filter felt structure, it pastes mixed fiber layer by the woven base cloth layer that forms of acrylic fiber symmetrically at the upper and lower faces of base cloth layer.
Described mixed fiber layer is to be formed by terylene and acrylic fiber blend.
Adopt technique scheme, its obvious technique effect is:
The utility model is that terylene and acrylic fiber composite are used the formation composite filter felt, learn from other's strong points to offset one's weaknesses, effect stack, remedied the deficiency of Single Fiber, have that intensity is high, hydrolytic resistance is good, non-oxidizability is good, wearability is strong, filter effect is good, the plurality of advantages such as long service life, cost are low, and organic and inorganic acid is had good resistance, applicable in the cement industry to the smoke harnessing of high-humidity gas fume under the lower operating mode of temperature requirement.
Described terylene and acrylic fiber composite filter felt, has splendid anti-hydrolytic performance, this depends on the intrinsic anti-hydrolytic performance of acrylic fiber self, with terylene and acrylic fiber composite, can effectively overcome the weakness that terylene easily is hydrolyzed, improve the anti-hydrolytic performance of composite filter felt comprehensively, reduce filter bag and lost efficacy in advance because of hydrolysis, prolonged the service life of composite filter felt.
Description of drawings
Fig. 1 is structural representation of the present utility model.
1 base cloth layer, 2 mixed fiber layers.
The specific embodiment
The utility model will be further described below with reference to accompanying drawing.
As shown in Figure 1, the utility model has disclosed a kind of composite filter felt structure.This filter felt is layer structure, and the centre is base cloth layer 1, pastes symmetrically mixed fiber layer 2 at the upper and lower faces of base cloth layer 1.
The utility model adopts non-woven technology to reinforce the composite filter felt structure of bonding formation base cloth layer 1 and mixed fiber layer 2, to acrylic fiber and polyster fibre compound use learn from other's strong points to offset one's weaknesses, effect stack, remedied the deficiency of Single Fiber, have that intensity is high, hydrolytic resistance is good, non-oxidizability is good, wearability is strong, filter effect is good, the plurality of advantages such as long service life, cost are low, and organic and inorganic acid is had good resistance, applicable in the cement industry to the smoke harnessing of high-humidity gas fume under the lower operating mode of temperature requirement.
The other composite filter felt of this terylene and acrylic fiber, has splendid anti-hydrolytic performance, this depends on the intrinsic anti-hydrolytic performance of acrylic fiber self, with terylene and acrylic fiber composite, can effectively overcome the weakness that terylene easily is hydrolyzed, improve the anti-hydrolytic performance of composite filter felt comprehensively, reduce filter bag and lost efficacy in advance because of hydrolysis, prolonged the service life of composite filter felt.
