SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a: in order to solve the problem that the treatment effect of the existing filter felt is not ideal aiming at the characteristics of high temperature, strong corrosivity and large dust amount, the modified acrylic fiber coating spunlace filter felt is provided.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a modified acrylic fiber coating water thorn filter felt, includes that the fine PTFE yarn machine that mixes of alkali glass weaves the filter cloth, the fine PTFE yarn machine that mixes of alkali glass weaves both sides of filter cloth are provided with first modified acrylic fiber and mixes PTFE fibrous surface course and the mixed PTFE fibrous surface course of second modified acrylic fiber respectively, the one side that the fine PTFE yarn machine that mixes of alkali glass weaves the filter cloth is kept away from to the mixed PTFE fibrous surface course of second modified acrylic fiber is provided with the PTFE coating.
Preferably, the content of the modified acrylic fiber in the first modified acrylic fiber mixed PTFE fiber surface layer and the second modified acrylic fiber mixed PTFE fiber surface layer is 60%, and the content of the PTFE fiber is 40%.
Preferably, the fiber web is reinforced by high-pressure water jet among the alkali-free glass fiber mixed PTFE yarn woven filter cloth, the first modified acrylic fiber mixed PTFE fiber surface layer and the second modified acrylic fiber mixed PTFE fiber surface layer.
Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses use the fine PTFE yarn machine of mixing of alkali glass of no glass to weave the filter cloth as the substrate, the tensile strength of filter material has been increased, the dimensional stability and the service temperature of filter material have been improved, the life and the filter effect of filter material have greatly been prolonged, this filter felt has better mechanical strength, can be suitable for the deashing of high-frequency to handle, mix the PTFE fibre with modified acrylic fibre and consolidate through water thorn and form the surface course, it is applicable in high temperature, the flue gas dust removal of strong corruption, the additional one deck PTFE coating of dust-facing surface further strengthens this filter felt's filtration efficiency and corrosion resisting property, and promote its easy deashing effect.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the figure: 1. weaving filter cloth by using alkali-free glass fiber mixed PTFE yarns; 2. a first modified acrylic mixed PTFE fiber surface layer; 3. a second modified acrylic fiber mixed PTFE fiber surface layer; 4. and (3) coating PTFE.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1, the modified acrylic fiber coating spunlace filter felt comprises an alkali-free glass fiber mixed PTFE yarn woven filter cloth 1, wherein a first modified acrylic fiber mixed PTFE fiber surface layer 2 and a second modified acrylic fiber mixed PTFE fiber surface layer 3 are respectively arranged on two sides of the alkali-free glass fiber mixed PTFE yarn woven filter cloth 1, and a PTFE coating 4 is arranged on one side, far away from the alkali-free glass fiber mixed PTFE yarn woven filter cloth 1, of the second modified acrylic fiber mixed PTFE fiber surface layer 3.
The utility model discloses use the fine PTFE yarn machine of mixing of alkali glass of no glass to weave filter cloth 1 as the substrate, increased the tensile strength of filter material, improved the dimensional stability and the service temperature of filter material, greatly prolonged the life and the filter effect of filter material to modified acrylic fibres mix the PTFE fibre and consolidate through water thorn and form the surface course, applicable in high temperature, the flue gas dust removal of strong corruption, PTFE coating 4 further strengthens the filtration efficiency and the corrosion resisting property of this filter felt.
Please refer to fig. 1, the content of the modified acrylic fiber in the first modified acrylic fiber mixed PTFE fiber surface layer 2 and the second modified acrylic fiber mixed PTFE fiber surface layer 3 is 60%, the content of the PTFE fiber is 40%, the utility model discloses a fiber surface layer made by carding and web-forming process after fully mixing 60% of the modified acrylic fiber and 40% of the PTFE fiber, applicable to the flue gas dust removal of high temperature and strong corrosion.
Please refer to fig. 1 heavily, adopt high pressure water jet to consolidate the fibre net between alkali-free glass fibre mixed PTFE yarn woven filter cloth 1, first modification acrylic fibre mixed PTFE fibre surface course 2, the second modification acrylic fibre mixed PTFE fibre surface course 3, the utility model discloses the fibre net is conveyed the commentaries on classics thigh water thorn district by the defeated net curtain and is carried out high pressure water jet and entangle the reinforcement, after 5 times of squirt high pressure jets, fibre net stable in structure, effectively entangles between the fibre, and the surface is levelly and smoothly even.
