Abstract
The utility model discloses a kind of corrosion-resistant acrylic resin coating high-temp filter felt, aramid fiber 1313 is punctured repeatedly by pricker on aramid fiber base fabric two sides, it reinforces obvolvent and obtains filter felt, surface refractory acrylic resin coating is carried out by transfer method in the dust-collecting face of filter felt.The utility model has the advantages that high temperature resistant, hydrolysis, corrosion-resistant, permeability is good, surface is smooth, dust adhesive force is small, equipment resistance is small, energy consumption is small.
Description
Technical field
It is the utility model relates to the technical field that flue gas ash removal after a kind of high-temperature flue gas denitration filters, in particular to a kind of resistance to
Corrode acrylic resin coating high-temp filter felt.
Background technique
The industries such as steel, cement, smelting all use the denitration process of SNCR, and a large amount of steam can be generated during out of stock
With other corrosive substances.Current filtering material is unable to satisfy high temperature requirement, this is the place that the application needs to be improved.
Utility model content
Technical problem to be solved in the utility model is to provide for a kind of good permeability, high temperature resistant, hydrolysis, corrosion resistant
Lose acrylic resin coating high-temp filter felt.
For the technical problem more than solving, the utility model provides a kind of corrosion-resistant acrylic resin coating high-temp mistake
Felt is filtered, is punctured aramid fiber 1313 repeatedly by pricker on aramid fiber base fabric two sides, obvolvent is reinforced and obtains filter felt, in mistake
The dust-collecting face for filtering felt carries out surface refractory acrylic resin coating by transfer method.
The transfer method carries out surface refractory acrylic resin coating, is by high temperature resistant and corrosion resistant acrylic resin
Liquid is equably coated in the surface of filter felt by transferring roller, reaches surface micropore and is automatically repaired function.
The filter felt with a thickness of 2.5 ± 0.2mm, the dust-collecting face of filter felt becomes more to cause through acrylic resin reparation
Close, average pore size is at 0.8 micron, grammes per square metre 580g/m2Or density 0.23g/cm3, the Air permenbility control of coating is in 120L/
dm2.min。
The heatproof of the utility model filter felt continues at 200 degree, instantaneously at 250 degree；Acrylic resin resistant to high temperature it is resistance to
Warm nature is at 200 degree or more.
Superior effect of the utility model is:
1) the utility model filter felt has high temperature resistant, hydrolysis, corrosion resistant excellent performance；
2) the utility model filter felt have permeability is good, surface is smooth, dust adhesive force is small, equipment resistance is small, energy
Consume small advantage.
Detailed description of the invention
The accompanying drawings constituting a part of this application is used to provide a further understanding of the present invention, this is practical
Novel illustrative embodiments and their description are not constituteed improper limits to the present invention for explaining the utility model.
In the accompanying drawings:
Fig. 1 is the structural schematic diagram of the utility model；
Figure label explanation:
1-acrylic resin coating；2-aramid fiber 1313 layers；
3-aramid fiber base fabrics.
Specific embodiment
The embodiments of the present invention are described in detail below in conjunction with attached drawing.
As shown in Figure 1, the utility model provides a kind of corrosion-resistant acrylic resin coating high-temp filter felt, in aramid fiber base
3 two sides of cloth is punctured aramid fiber 1313 by pricker repeatedly, is reinforced obvolvent and is obtained filter felt, in the dust-collecting face of filter felt
Surface refractory acrylic resin coating 1 is carried out by transfer method.
Aramid fiber 1313 is combed by nonwoven acupuncture technique, intermediate folder aramid fiber base fabric, carry out pre- needle, main needle,
It repairs needling process and obtains aramid fiber filter felt in surface.
Physical treatment is carried out to aramid fiber filter felt, handle, singe including thermal finalization, press polish, surface it is super smooth whole
Reason.
Coating treatment is carried out to the dust-collecting face of aramid fiber filter felt, surface refractory acrylic acid tree is carried out by transfer method
Rouge coating.
Out of stock application field of the utility model filtering material especially suitable for the industries such as steel, cement, smelting NCR.
The foregoing is merely the preferred embodiments of the utility model, are not intended to limit the utility model, for this
For the technical staff in field, various modifications and changes may be made to the present invention.It is all in the spirit and principles of the utility model
Within, any modification, equivalent replacement, improvement and so on should be included within the scope of protection of this utility model.
