Abstract
The utility model discloses a polytetrafluoreethylene fiber high-tempearture-resistant Teflon membrane needled filter felt, which is characterized by comprising a base fabric layer and a filter layer, wherein the filter layer is formed by carding polyetetrafluoreethylene fibers, the base fabric layer is formed by transversely and longitudinally interweaving polytetrafluoroethylene filament yarns, and a Teflon emulsion fully-impregnated membrane layer respectively covers the surface of the fibers of the base fabric layer and the filter layer. Compared with the prior art, the polytetrafluoreethylene fiber high-tempearture-resistant Teflon membrane needled filter felt has advantages that polytetrafluoroethylene (PTFE) has extreme chemical inertness, can resist acid-alkali corrosion in full coverage of pH values, has stable properties under a strict condition and can resist the corrosion of different harmful and toxic compositions generated by the burning of garbage. The cross section of the fiber is specially-shaped, the filter area can be improved, and the filter precision can be improved. Then the membrane treatment is carried out, the Teflon layer has good anti-bonding property, and the filter material can play a role in gas-solid separation under a corrosive high-temperature environment, so that the service life of the filter material can be maintained.
Description
[technical field]
The utility model relates to the high temperature resistant teflon of a kind of polytetrafluoroethylene fibre and oozes the film needled filtering felt.
[background technology]
Along with the development of national economy urban construction, the amount of domestic waste is the trend that increases year by year.The field of burying of the processing of landfill in the past has been difficult to satisfy the demand, and causes secondary pollution.So adopting incineration technology is that to have a garbage disposal thorough, and have can outer energy supply source and reclaim the income of taking metal.But owing to burn produce harmful, poisonous flue dust must strictly purify.
The harmful poisonous composition that consumer waste incineration produces is very complicated, wherein also comprises some trace and metal, like mercury, and cadmium, lead, chromium, tweezer, copper etc., and also the granularity of the particle that produces is superfine, and viscosity is high.The big 23-30% of flue dust water capacity not only has oxygen, many sulfur oxides, and carbon dioxide, many nitrogen oxides also have sour gas etc.It is extremely harmful to human body also possibly to produce carcinogens such as bioxin and furans in the burning.
[utility model content]
The utility model provides the high temperature resistant teflon of a kind of polytetrafluoroethylene fibre to ooze the film needled filtering felt in order to solve the above-mentioned deficiency of prior art.
The above-mentioned purpose of the utility model realizes through following technical scheme: the high temperature resistant teflon of a kind of polytetrafluoroethylene fibre oozes the film needled filtering felt; It is characterized in that: it comprises base cloth layer and filter course; Said filter course is made up of the polytetrafluoroethylene fibre carding; Said base cloth layer is interweaved by polytetrafluoroethylene (PTFE) long filament longitude and latitude and constitutes, and the fiber surface of said base cloth layer and filter course is all covering the full dipping of teflon emulsion and oozing rete.
The gross thickness of said base cloth layer and filter course is 1.2mm.
The utility model advantage compared with prior art is: PTFE has extreme chemical inertness; Soda acid in the whole pH value scopes of ability corrodes; Under harsh conditions, show stable properties, so can keep out the corrosion of the various harmful poisonous compositions of waste incineration generation.The fibre section is an abnormity, can improve filter area, thereby improves filtering accuracy.Ooze film again and handle layer of teflon and have good anti stick property, filtrate can reach the effect that gas-solid two is separated and the service life that helps keeping filtrate under the corrosivity hot environment.

Fig. 1 is the structural representation of the utility model;
Fig. 2 is the structural representation of the utility model base cloth layer and filter course.
In the accompanying drawing, the 1-base cloth layer; The 2-filter course.
[specific embodiment]
Below in conjunction with accompanying drawing the utility model is further detailed:
As shown in Figure 1; The high temperature resistant teflon of a kind of polytetrafluoroethylene fibre oozes the film needled filtering felt; It is characterized in that: it comprises base cloth layer 1 and filter course 2, and as shown in Figure 2, said filter course 2 is made up of the polytetrafluoroethylene fibre carding; Said base cloth layer 1 is interweaved by polytetrafluoroethylene (PTFE) long filament longitude and latitude and constitutes, and the fiber surface of said base cloth layer 1 and filter course 2 is all covering the full dipping of teflon emulsion and oozing the rete (not shown).
The gross thickness of said base cloth layer 1 and filter course 2 is 1.2mm.
The production procedure of the utility model is: at the bottom of filter bag tube → filter bag tube reinforcing → filtration sack → filter bag.
Then the present technique scheme implementation finishes.
