Abstract
The utility model discloses a prickling filter felt of a polyimide fibre surface, which comprises a dust attaining layer made of polyimide (P84) fibre, a first adhesive layer made of polyphenyl thioether (PPS) fibre, a base cloth layer made of polyphenyl thioether (PPS) short yarn base cloth or polyfluortetraethylene (PTFE) long yarn base cloth, and a second adhesive layer made of polyphenyl thioether (PPS) fibre. The first adhesive layer covers on the base cloth layer which covers on the second adhesive layer, and the first adhesive layer, the base cloth layer and the second adhesive layer are fixed and connected mutually by the composite needling way. The dust attaining layer covers on the first adhesive layer, the dust attaining layer and a composite needling body are connected and fixed mutually by the composite needling way again, wherein, the composite needling body is formed by the first adhesive layer, the base cloth layer and the second adhesive layer. Because the compact polyimide (P84) fibre layer is used as the outermost layer which directly contacts with dust, the filtering precision of the filter material can be improved, the differential pressure of the filter material is reduced, the service life of the filter material is prolonged, the concentration of emission of the smoke can be controlled to be less than 30mg/Nm<3>, and the energy consumption and the operation cost of a dust catcher can be lowered.
Description
Technical field
The utility model relates to industrial smoke dust removal by filtration technical field, particularly relates to a kind of polyimide fiber surface layer needled filtering felt.
Background technology
From on January 1st, 2004, all " construction project statement of the effect to be occasioned on the environment " be newly-built, enlarging, the reconstruction Thermal Power Plant Construction project by examining, and the highest permission concentration of emission of its boiler smoke is 50mg/Nm
3, the 200mg/Nm of this and old standard
3Compare and want much strict.Present most electrostatic precipitation system can't reach 50mg/Nm
3Emission request, need transform, usually the electric field of expansion quantity to be arranged, uses bag type dust removing technology, transform the rear end electric field be electricity-bag composite dedusting technology etc. as bag-type dusting to the renovation technique that adopts.
Its front end of electricity-bag composite dedusting technology is provided with electric field (cathode and anode), and in the rear end filter bag is set.When flue gas when the electric field, the most dust in the flue gas will be collected, and the flue gas that only contains low amounts of dust enters the rear portion filter bag, is finished the filtration of rear end dust by bag-type dusting.Flue gas is behind electric field, and the soot dust granule that particle diameter is bigger is accepted by electric field, and the residue dust size is very little, and concentration is lower.Used conventional high-temperature filter material is in the face of the very little dust of particle diameter, and it is very fast more easily to be caused resistance to rise by the deep layer of dust incision filtrate, shortens service life; Running resistance is higher, problems such as energy consumption increasing.
