Abstract
The utility model discloses a high-temperature-resistant needled felt with laminated PTFE (Polytetrafluoroethylene) fiber, which is of a layered structure. PTFE fiber layers are respectively bonded to the upper surface and the lower surface of PTFE base cloth symmetrically; and a PTFE microcellular film which is compounded by a needling machine is laminated on a fiber layer at a windward surface. The high-temperature-resistant needled felt provided by the utility model has the advantages of good chemical gas corrosion resistance, high stretching intensity, and a good dust stripping performance by adopting surface filtration, ash can be removed easily, the ash removing frequency of a deduster is lowered, and the service life of a filter material is prolonged.
Description
Technical field
The utility model relates to a kind of for liquid-solid separation and gas-solid separation technology field fiber needled felt, particularly the fiber film-coated high temperature resistant Nomex of a kind of PTFE.
Background technology
At present, in the lower occasion of some filtrating smoke dust temperature, as iron-smelter, garbage burning factory, the blast furnace gas filtering material that uses such as long, its heat endurance, chemically-resistant gas attack, filtering accuracy are relatively poor, and the service life of filtrate is very low.
The utility model content
Technical problem to be solved in the utility model is that a kind of deashing frequency that reduces deduster will be provided, and improves the filtrate fiber film-coated high temperature resistant Nomex of PTFE in service life.
In order to solve above technical problem, the utility model provides a kind of PTFE fiber film-coated high temperature resistant Nomex, this Nomex is layer structure, the sticking PTFE fibrage of upper and lower surface difference symmetry at the PTFE base cloth covers one deck compound microporous teflon membran of needing machine on the fibrage of windward side.
Superior effect of the present utility model:
1) the chemically-resistant gas attack is good, the hot strength height;
2) adopt surface filtration, the stripping performance of dust is good, easy-to-clean ash;
3) the deashing frequency of reduction deduster, the service life of having improved filtrate.
Description of drawings
Fig. 1 is structural representation of the present utility model;
The number in the figure explanation:
1-microporous teflon membran; 2-PTFE fibrage;
3-PTFE base cloth.
The specific embodiment
Below in conjunction with Fig. 1 and specific embodiment the utility model is described in detail.
The utility model provides a kind of PTFE fiber film-coated high temperature resistant Nomex, the fiber film-coated high temperature resistant Nomex of described PTFE is layer structure, the sticking PTFE fibrage 2 of upper and lower surface difference symmetry at PTFE base cloth 3 covers one deck compound microporous teflon membran 1 of needing machine on the fibrage 2 of windward side.
Gas is contact microporous teflon membran 1 earlier, dust impurity in microporous teflon membran 1 adsorbed gas carries out deashing to be handled, secondly by PTFE fibrage 2 the harmful chemical gas in the gas is filtered, the PTFE fibrage 2 of transferring by PTFE base cloth 3 carries out the filtration second time at last, reduce the deashing frequency of deduster, improve the service life of filtrate.
Continuous operation temperature of the present utility model is 120 ℃ ~ 250 ℃, moment serviceability temperature be 260 ℃, brute force 〉=900N/5 * 20 ㎝ radially, broadwise brute force 〉=1000N/5 * 20 ㎝, radial fragmentation percentage elongation≤45%, broadwise elongation at break≤45%, air permeability 2-5m
