Along with increasingly stricter to environment protection treating of country, people are to industrial fumes Comprehensive Treatment of Pollution technology
Increasingly pay close attention to and pay attention to.Bag type dust removing technology due to advantages such as filter efficiency height, length in service life,
It is more and more wider that industrial fumes administer field application.But, comprehensive control smelting iron and steel, waste incineration,
When the industries such as coal-burning power plant, cement, chemical industry exist high-risk (flammable, explosive) flue dust, owing to filtrate amasss
Poly-static sparking, causes detonation even to explode equivalent risk, thus to the antistatic of filter bag and resistance to elevated temperatures
Have higher requirement.General industrial dust reaches (i.e. explosion limit) after to a certain degree in concentration
Such as factors such as electrostatic discharge spark or extraneous igniting, the most easily cause blast and fire.As: flour dirt,
Chemical industry dust, coal dust etc. such as static discharge have the possibility of blast.At present at the antistatic of filter bag
Reason mainly has blending method and face coat method.Blending method mainly uses and conventional fibrous material is changed with passing through
The fiber after property with electric conductivity carries out the method manufacture antistatic filter bag of blending, but due to after modified
Conductive fiber performance affected relatively big by working conditions such as flue-gas temperature, corrosive gas, humidity, significantly
Limit the range of application of this filter bag.Use face coat method to be confined to coat one layer at material surface to lead
Electrocoating paint, to improve antistatic property, is difficult to control inner surface resistance and is in relatively low scope, and electrostatic consumption
Scattered speed is slower., there is poorly conductive, machinery in the gas cleaning filter bag using these technology to prepare at present
The low inferior problem of intensity difference, wearability and heat-resisting quantity.
Summary of the invention
In view of this, this utility model is directed to a kind of antistatic dedusting filtering bag, to solve current flue gas
Purify filter bag electric conductivity and the low inferior problem of bad mechanical strength, wearability and heat-resisting quantity.

Alkene/carbon nanomaterial hybrid coating；Described bottom, the first carbon nanomaterial coating, base cloth layer, second
Connected by acupuncture between carbon nanomaterial coating, polyimides superfine fibre filter material layer adjacent two layers.
Further, the carbon in described first carbon nanomaterial coating, described second carbon nanomaterial coating
One in graphene nanometer sheet that nano material is selected from, CNT, graphite.
Further, the thickness of described first carbon nanomaterial coating is 100～500nm, described second carbon
The thickness of nano-material coating is 100～500nm.
Further, the carbon nanomaterial in described politef/carbon nanomaterial hybrid coating is selected from
Graphene nanometer sheet, CNT, one in graphite.
Further, described bottom is by aramid fiber, glass fibre, polyimide fiber, polyphenylene sulfide
The non-woven fabrics that one or more fiber blends in ether fiber, polytetrafluoroethylene fibre become.
Further, the grid cloth that described base cloth layer is made into by polytetrafluoroethylfilament filament fiber.
Further, the total grammes per square metre of described base cloth layer is 100～500 grams/m, and its warp-wise density is

Relative to prior art, a kind of antistatic dedusting filtering bag described in the utility model has following excellent
Gesture:
A kind of antistatic dedusting filtering bag described in the utility model, its politef/carbon nanomaterial is miscellaneous
Change coating, as meeting knoisphere, is possible not only to improve the antistatic property of filter bag, it is also possible to improve the anti-of filter bag
Oxidisability, acid-alkali-corrosive-resisting ability, deashing ability and intensity；Polyimides superfine fibre layer is by poly-
The leaf type structure of imide fiber uniqueness makes it have bigger specific surface area, increases the hole of carpet veneer
Rate and aperture are less, thus improve its filter efficiency；First carbon nanomaterial coating and the second carbon nanometer material
The setting of material coating, solves the problem that filter bag inner surface electrostatic dissipation is slow, can also strengthen filter bag simultaneously
Anti-dust erosive wear, increase the service life；And base cloth layer plays the effect of skeletal support；Bottom
Be conducive to the air-flow entering filter bag to pass through, reduce resistance, it is ensured that breathability.
