Single in the filter felt structure of existing bag-type dust equipment, efficiency of dust collection is limited, for high temperature, corrosive fume dedusting
Time, dust removing effects is poor.
Utility model content
The purpose of this utility model is to provide a kind of heat resistance fiber filter felt, it is possible to improve asking of prior art existence
Topic, by using melamine fiber to make high-temperature-resistant layer structure, it is achieved while the resistance to elevated temperatures of filter felt, utilize trimerization
The filter effect of cyanamide fiber, forms multiple filtration structure with the combination of composite acupuncture fibrous layer, improves the filter effect of filter felt.
This utility model is achieved through the following technical solutions:
A kind of heat resistance fiber filter felt, includes meeting knoisphere, high-temperature-resistant layer, composite acupuncture fibrous layer and basal layer, institute successively
The knoisphere of meeting stated is that polyimide fiber is made, and described high-temperature-resistant layer is that melamine fiber is made, described meet knoisphere and
Mutually bondd by phenolic resin glue-line between described high-temperature-resistant layer.
Further, for this utility model is better achieved, described composite acupuncture fibrous layer is polytetrafluoroethylene fibre
Make.
Further, for this utility model is better achieved, described basal layer is that ultra-fine polyester fiber is made.
Further, for this utility model is better achieved, described composite acupuncture fibrous layer and described basal layer it
Between be provided with epoxy glue layer.
Further, for this utility model is better achieved, described knoisphere of meeting is 2 strata imide fibers intersection net layings
Forming layer structure, described high-temperature-resistant layer is the layer structure that 2 layers of melamine fibers intersection net laying is formed.
This utility model compared with prior art, has the advantages that
(1) this utility model meets knoisphere by using polyimide fiber to make, it is possible to utilize its high temperature resistant, corrosion resistance
Can, it is conveniently used for high temperature, corrosivity flue dust dedusting, helps to maintain the stability of filter felt；
(2) this utility model is by using melamine fiber to make high-temperature-resistant layer, it is possible to utilize it high temperature resistant, corrosion-resistant
Performance, helps to maintain the stability of structure, meanwhile, utilizes its architectural characteristic, it is achieved the filtration to dust, fine with composite acupuncture
Dimension layer constitutes combined filtration structure, is favorably improved integrally-built filter effect.
Accompanying drawing explanation
In order to be illustrated more clearly that the technical scheme of this utility model embodiment, will use required in embodiment below
Accompanying drawing be briefly described, it will be appreciated that the following drawings illustrate only some embodiment of the present utility model, the most should be by
Regard the restriction to scope as, for those of ordinary skill in the art, on the premise of not paying creative work, also may be used
To obtain other relevant accompanying drawings according to these accompanying drawings.
Fig. 1 is this utility model overall structure schematic diagram.
Wherein: 101. meet knoisphere, 102. high-temperature-resistant layers, 103. composite acupuncture fibrous layers, 104. basal layeres, 105. phenolic aldehyde trees

Detailed description of the invention
Below in conjunction with specific embodiment, this utility model is described in further detail, but embodiment party of the present utility model
Formula is not limited to this.
Embodiment 1:
As it is shown in figure 1, a kind of heat resistance fiber filter felt, include successively meeting knoisphere 101, high-temperature-resistant layer 102, composite acupuncture fibre
Tieing up layer 103 and basal layer 104, described knoisphere 101 of meeting is made for polyimide fiber, and described high-temperature-resistant layer 102 is trimerization
Cyanamide fiber is made, and described meeting between knoisphere 101 and described high-temperature-resistant layer 102 is the most viscous by phenolic resin glue-line 105
Knot.
Generally using temperature due to polyimide fiber is 260 degrees Celsius, and its resistance to elevated temperatures is good, and has good
Saturability, plays certain filter effect, therefore, uses polyimide fiber to make and meet knoisphere, it is possible to play certain filtration
While effect, there is effect high temperature resistant, corrosion resistant, contribute to extending the service life of filter felt；
The characteristic do not shunk under 300 celsius temperatures owing to melamine fiber has, do not melt, and as
High-temperature-resistant layer, it is possible to utilize the filter effect that it is good, filter felt is high temperature resistant, anticorrosion effect, meanwhile, it is capable to keep away to play raising
Exempt from filter felt to deform under high-temperature flue gas effect, coordinate with composite acupuncture fibrous layer, it is possible to increase integrally-built filtration
Effect；
