Abstract
The utility model relates to a PTFE bag-type filter material. The bag-type filter material of the existing bag-type dust remover has the poor adaptability for the different characters of flue gas and powder dust and other problems. The utility model is characterized in that the upper end surface of a base cloth of PTFE bag-type filter material is provided with a PTFE fiber layer, the lower end surface of the base cloth is also provided with a PTFE fiber layer, the base cloth is woven with the PTFE single-stranded long fiber, the PTFE fiber layer on the upper end surface of the base cloth is formed by the PTFE short fiber, and the PTFE fiber layer on the lower end surface of the base cloth is formed by the PTFE short fiber. The PTFE bag-type filter material of the utility model is characterized by the strong high-temperature resistance, acid and alkali corrosion resistance and oxidation resistance, and not hydrolyzing. The dust remover's bag made of the bag-type filter material of the utility model can be applied to the treatment for various characters of flue gas and powder dust, particularly can roundly adapt to the treatment for the flue gas of the garbage incinerator.
Description
Technical field:
The utility model relates to a kind of cloth bag of sack cleaner, particularly relates to a kind of Sack filtering material of polytetrafluoroethylene.
Background technology:
Reinforcement along with environmental protection consciousness; and to the concern of health; the application of deduster more and more widely in industry; at present to flue gas; sack cleaner is all adopted in the processing of dust; the cloth bag filtrate of sack cleaner is mainly selected for use aromatic polyamide fibre; polyphenylene sulfide fibre; poly-aromatic imide fiber and glass fibre etc.; though these cloth bag filtrates respectively have different advantages; but to face flue gas of different nature; dust; also exist different shortcomings; to reduce as aromatic polyamide fibre operating temperature when moisture and chemical composition are arranged, especially at SO
2Exist, when having moisture, can be corroded, strength retention ratio reduces, and polyphenylene sulfide fibre is to the oxidant sensitivity, poly-aromatic imide fiber be not hydrolysis, price is higher and glass fibre to the corrosion-resistant of hydrofluoric acid, highly basic, thus, can in practical operation, reduce the service life of cloth bag, and can make the sack cleaner complete machine not good enough the effect of flue gas, dust processing, simultaneously, also influenced the continuous maintenance operate as normal of deduster complete machine.
Summary of the invention:
The purpose of this utility model is that a kind of improved Sack filtering material of polytetrafluoroethylene will be provided, it not only can be handled at flue gas, the dust of different character effectively, and, can also prolong service life of cloth bag, simultaneously, also promoted the complete machine performance of sack cleaner.
The scheme of technology of the present utility model is to achieve the above object: Sack filtering material of polytetrafluoroethylene of the present utility model has a described base cloth, be shaped on a polytetrafluoroethylene fibre layer on the upper surface of described base cloth, also be shaped on a polytetrafluoroethylene fibre layer on the lower surface of described base cloth.Described base cloth is made into by the sub-thread long fibre of polytetrafluoroethylene (PTFE), polytetrafluoroethylene fibre layer on the upper surface of described base cloth is formed by polytef flocks, and the polytetrafluoroethylene fibre layer on the lower surface of described base cloth is also formed by polytef flocks.
Because the utility model has improved the cloth bag filtrate of existing sack cleaner, on cloth bag filtrate base cloth, all be manufactured with a polytetrafluoroethylene fibre layer on the lower end surface, and the polytetrafluoroethylene fibre layer is all constituted by polytef flocks, described base cloth adopts the sub-thread long fibre of polytetrafluoroethylene (PTFE) to be made in addition, the cloth bag filtrate that is made of polytetrafluoroethylene fibre has best corrosion resistance and hear resistance, can resist oxidation and surface contaminants, do not become fragile, do not rupture, do not burn, extremely strong hydrolytic resistance is arranged, all better than the anti-vapour permeability of any material, like this, enlarged cloth bag greatly to different flue gases, the adaptability of dust, improve the service life of cloth bag, ensured the normal operation of sack cleaner, also make dust removing effects get strong guarantee.
Description of drawings:
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is the structural representation of Sack filtering material of polytetrafluoroethylene of the present utility model.
The specific embodiment:
Below with reference to accompanying drawing to Sack filtering material of polytetrafluoroethylene of the present utility model and be described in further detail.
Referring to Fig. 1, the Sack filtering material of polytetrafluoroethylene of this utility model is made up of the polytetrafluoroethylene fibre layer (3) on the lower surface of polytetrafluoroethylene fibre layer (2) on the upper surface of described base cloth (1), described base cloth (1) and described base cloth (1).
Described base cloth (1) is made into by the sub-thread long fibre of polytetrafluoroethylene (PTFE).
Polytetrafluoroethylene fibre layer (2) on the upper surface of described base cloth (1) is formed by polytef flocks.
Polytetrafluoroethylene fibre layer (3) on the lower surface of described base cloth (1) is formed by polytef flocks.
Described Sack filtering material of polytetrafluoroethylene of the present utility model passes through needling process by polytef flocks, acupuncture is made the polytetrafluoroethylpunched punched felt filtrate on the described base cloth that is made into the sub-thread long fibre of polytetrafluoroethylene (PTFE), and be made into cloth bag, its have high temperature resistant, acid and alkali resistance burn into oxidation resistance by force, characteristic that can not hydrolysis.The cloth bag of the deduster that cloth bag filtrate of the present utility model is made especially can adapt to the processing of flue gas of garbage furnace all sidedly applicable to the flue gas of various character, the processing of dust.
