Background technology
At present, in industrial fumes and powder body, acid and alkali corrosion gas content is high, and chemical environment is complicated, and moisture is big,
And the flue gas big temperature of fluctuation is high.In sack cleaner is applied, ash-laden gas can be needled what felt became
Filter bag carries out effective purifying and dedusting.But, filter effect often due to filter structure material composition and after locate
The difference of reason method and different.
Generally in incinerator, biomass boiler, high temperature smelting furnace, use common PTFE Nomex or
Person's PTFE compound spiked felt, cost is high, and owing to the characteristic difficulty of PTFE and glass is compound, the most wear-resisting,
Easily wash away lower fiber fractionation or breakage at high speed dust.
P84 is a kind of fire-retardant, fiber filtering that heatproof is stable, and under conditions of 240 DEG C of temperature, P84 gathers
The machinery of imide fiber filtrate will not change, and high-temperature resistant is up to 260 DEG C.P84 fiber filtering does not has
Melting temperature, in the most golden yellow.P84 polyimide fibers filtrate is not hygroscopic fiber filtering,
Under the relative humidities of 65%, the water absorption of about 3%.P84 be mainly used in asphalt mixing, cement kiln,
Dry, burn, smelt, the gas cleaning of the process such as various industry kiln, coal-burning boiler and waste incineration, and
It is widely used in the technique that concentration of emission requirement is higher.
Utility model content
The purpose of this utility model is to provide a kind of P84 compound spiked felt with high temperature resistant corrosion resistant high-strength.
This utility model is achieved through the following technical solutions above-mentioned purpose:
A kind of P84 compound spiked felt with high temperature resistant corrosion resistant high-strength, including middle base cloth layer, institute
The upper surface stating base cloth layer is provided with superfine fibre dust-collecting face layer, and the lower surface of described base cloth layer is provided with ventilative clean gas
Surface layer, described base cloth layer, described superfine fibre dust-collecting face layer and described ventilative clean gas surface layer needle felting；Institute
The upper surface stating superfine fibre dust-collecting face layer is provided with PTFE emulsion dipping layer.
Further, described superfine fibre dust-collecting face layer is P84 fiber and ultra-fine PTFE fiber and alkali-free glass
Fiber mixing is compound to be constituted.Wherein the P84 fiber of trilobal cross has cohesive force between higher fiber, permissible
It is combined with more smooth PTFE fiber and alkali-free glass fibre, it is provided that high-tenacity.
Further, described superfine fibre dust-collecting face layer has microcellular structure.
Further, described ventilative clean gas surface layer is PTFE fiber and the compound composition of alkali-free glass fibre mixing.
Further, described base cloth layer is the enhancing base fabric being made into by varicosity alkali-free glass fiber yarn.It is acupuncture
The enhancement layer of felt, provides overall strength for Nomex, has the highest strength, it is ensured that filter whole service life.
Compared with prior art, a kind of P84 with high temperature resistant corrosion resistant high-strength of the present utility model is combined
Nomex has that wearability is good, corrosion-resistant, high temperature resistant, hydrolysis, filtering accuracy high, fracture strength high and
Service life the advantage such as length, can substitute for high common PTFE Nomex:
The most high temperature resistant: can to use at dusty gas temperature is 260 DEG C～300 DEG C, it is adaptable to major part work
Condition scope；
2. filtering accuracy is high: superfine fibre dust-collecting face layer is due to ultra-fine P84, the fiber of PTFE fiber composition
Surface layer structure, it is possible to increase the filtering accuracy of filtrate, increases filter area, improves filtration velocity；
3. acid-alkali-corrosive-resisting ability is strong, stable chemical performance: the excellent antiacid caustic corrosion of PTFE fiber and anti-
Oxidation can be effective against corrosive gas in flue gas, and the acid resistance making up glass is good but general the lacking of alkali resistance
Point, can use on the complex working conditions such as incinerator；
4. wearability is good: P84 fiber has cohesive force between higher fiber so that be not easy to produce cohesive force
PTFE fiber and alkali-free glass fibre be effectively combined, fibrous layer is difficult to be torn, and P84 fiber is simultaneously
There is good anti-wear performance, thus there is higher wearability；
The highest strength and dimensional stability: the enhancing base fabric being made into due to varicosity alkali-free glass fibre yarn line
There is the highest strength, provide for filtrate entirety strength and ensure and stability；
6. service life is long: the Nomex tool of ultra-fine P84, PTFE fiber and alkali-free glass fibre composition
Having the feature of efficient low-resistance, dust is not easily accessible inside filtrate, reduces deashing frequency, and service life is longer；
The most cheap: economic performance is good, owing to major part uses alkali-free glass fibre, and eliminate height
High PTFE coating processes, reduces the use cost of filtrate.
A kind of P84 compound spiked felt with high temperature resistant corrosion resistant high-strength of the present utility model is applicable to flue gas
Temperature is high, dust changes greatly, dust concentration height, acidic and alkaline gas occasion greatly, particularly incinerator,
The industry such as new type nonaqueous cement, biomass boiler, high temperature smelting furnace and chemical industry, generating, Industrial Stoves
Flue gas ash removal field.
