Description
Technical field
The utility model belongs to industrial dedusting field more particularly to one kind for high-temperature flue gas filter pleated filter
Cloth bag.
Background technology
Sack cleaner (and electric-bag complex dust collector) is high-efficiency dust remover, widely applied a kind of heavy in countries in the world
The environmental protection equipment wanted.The sack cleaner overwhelming majority all makees filter cloth using Nomex at present, Nomex filter cloth usually by base fabric and
Fibre prickling is combined, and base fabric therein plays booster action, and just as the reinforcing bar in concrete, and base fabric is usually single
Layer.
With environmental requirement raising and adapt to the energy-saving and emission-reduction requirement that country proposes, sack cleaner (and electric bag
Complex dust collector) use it is more and more extensive.Sack cleaner is that the dust in flue gas is carried out using filter element i.e. filter bag
It intercepts, realizes purifying smoke.Filter bag becomes one of most important component in sack cleaner (and electric-bag complex dust collector),
It is most critical component.Filter bag is a kind of chemical fibre under normal conditions, its temperature tolerance and corrosion resistance by fiber characteristic
Influence.
Since flue-gas temperature is high, contains very high SOx and NOx, common PPS in flue gas in the industrial smokes such as coal-burning boiler
(polyphenylene sulfide) base fabric and PPS fibers can not meet the requirement used for a long time, so, former high-temperature flue gas administers general use
Electrostatic precipitator.The development of high-temperature filter material at present, as high temperature resistance filtration material PPS, P84 (polyimide fibers) obtain widely should
With so that bag filter becomes a kind of high-efficiency dust remover of mainstream.Particularly superpower weatherability fiber PTFE (polytetrafluoroethyl-nes
Alkene) production domesticization, bring the reduction of price, PTFE base fabrics and its fiber filter cloth start to apply in high-temperature flue gas, and obtained
Excellent effect.In the high-temperature flue gas processing of coal-burning boiler, the Nomex of PTFE base fabrics also has begun extensive use.
The public number Chinese patent for CN202666573U discloses a kind of plating film filtering material of filtration efficiency, including base
Cloth has Nomex face layer in the upper and lower surface of base fabric, and there is plated film in the outer surface of a face layer wherein.It is in use
By the tiny particles content that imperfect combustion is formed, entered in Nomex layer in the case where filtering wind action, filtrate is caused
Scald and breakage, so as to influence using effect.
Utility model content
Technical problem to be solved in the utility model be for background technology deficiency provide it is a kind of for high temperature cigarette
Air cleaner pleated filter cloth bag, can reduce the tiny particles content entered in Nomex, so as to reduce damage.
The utility model uses following technical scheme to solve above-mentioned technical problem
One kind is for high-temperature flue gas filter pleated filter cloth bag, it is by frame and the filter bag on frame
Connection composition；The filter bag is made of three bending filter membrane interconnections, and bending filter membrane is in W type gauffers, and three bendings are filtered
The tip position of film is connected with connecting line, and rhomboid cavity is formed between every two bending filter membranes after connection；Above and below filter bag
Both ends are mounted on by caulking gum on frame；It further includes and is set to the outermost alumina-silicate refractory fibre blanket of filter bag, it is described
Alumina-silicate refractory fibre blanket is equipped with double-deck and is sutured by way of fire resisting silk thread and by latitude and longitude, passes through connection after suture
Line is connect with bending filter membrane, the fire resisting cell compartment of several closings is formed between two layers of alumina-silicate refractory fibre blanket, in fire resisting cell compartment
The middle quartzy particulate matter of filling.
The fire resisting cell compartment is regular polygon.
The fire resisting cell compartment is square, and the length of side is not more than 2cm.
The left and right ends of the bending filter membrane are connect by reinforcing plate with frame.
The bending filter membrane is PTFE Nomex microporous membranes.
The utility model compared with prior art, has following technique effect using above technical scheme：
Firstth, PTFE (polytetrafluoroethylene (PTFE)) Nomexs microporous membrane is subjected to fold processing, improves the intensity of cloth, make it
The whole cloth bag of certain rigidity itself is formed with, without installing metal joist additional, avoids abrasion cloth bag, service life is long.
The secondth, double-deck alumina-silicate refractory fibre blanket, tool are set before PTFE (polytetrafluoroethylene (PTFE)) Nomexs microporous membrane
There is good fire resistance, the tiny particles content generated for lattice gear due to burn incompletely；Double-deck alumina-silicate refractory fibre blanket leads to
It crosses fire resisting silk suture and fills quartzy particulate matter, larger improves its fire resistance and durability, improves its intensity.
