Abstract
A mixed needle-punched filter felt comprises a base cloth layer, an outer adhesive layer attached to the outer side of the base cloth layer, and an inner adhesive layer attached to the inner side of the base cloth layer; the base cloth layer is the base cloth made from polytetrafluoroethylene filament by weaving; the outer adhesive layer and the inner adhesive layer are formed through compositing thorns by mixing polyimide fibers and polytetrafluoroethylene fabrics, which are then paved on the outer side and inner side of the base cloth layer. The mixed needle-punched filter felt with such a structure is characterized in high temperature resistance, high humidity resistance, good corrosion resistance, high filter precision, small filter pressure difference, and good spinning performance in production, and can control the concentration of gas emissions less than 30mg/Nm <3> and control the dioxin emissions for the exhaust in the processing of waster incineration less than or equal to 0.1Ng-TEQ/Nm <3>.
Description
Technical field
The utility model relates to industrial fumes gas dust removal by filtration technical field, specifically is meant a kind of mixing needled filtering felt.
Background technology
In recent years, along with National urban house refuse amount being higher than 10% speed sustainable growth every year, existing 200 cities are absorbed among rubbish surrounds in 660 cities, the whole nation, garbage disposal is extremely urgent.Because rubbish is carried out burning disposal, and to subtract appearance, decrement and innoxious degree all very high, the heat that burning process produces is used for generating electricity and can realizes the energy of rubbish simultaneously again, the waste incineration and generating electricity industry is just attracting increasing capital to quicken to pour in this environmental protection industry (epi), in a few years, the various places waste incineration project that starts one after another, the garbage power plant of whole nation planning and operation just has more than 100, and waste incineration is in the ascendant.
Because China's municipal refuse organic matter composition height, moisture content height, cause flue gas after the incineration treatment of garbage to have characteristics such as high temperature, high humidity, corrosivity are strong, make the incineration treatment of garbage treating tail gas quite harsh to the requirement of filtrate.Waste incineration and generating electricity regulation must be used sack cleaner, and apparent as the effect of the filtrate of sack cleaner core.Along with the further raising that dust emission is required, a lot of cities require dust emission less than 50mg/Nm
3, part developed area even reach 30mg/Nm
3The ， bioxin also requires less than 1 Ng-TEQ/Nm
3Or 0.1Ng-TEQ/Nm
3In addition, also have a lot of high temperature, corrosive gas to need to handle in fields such as smelting, cement, chemical industry, this all requires the research of filtrate to develop towards direction high temperature resistant, corrosion-resistant, high strainability.
The utility model content
Main purpose of the present utility model is to provide a kind of mixing needled filtering felt that is used for industrial fumes gas dust removal by filtration of high temperature resistant, corrosion-resistant, high strainability.
The utility model adopts following technical scheme: a kind of mixing needled filtering felt, the outer adhesion layer and the interior adhesion layer that is attached to the base cloth layer inboard that comprise base cloth layer and be attached to the base cloth layer outside, this base cloth layer is weaved the base cloth that forms for the polytetrafluoroethylene (PTFE) long filament, and this outer adhesion layer and interior adhesion layer are mixed with polytetrafluoroethylene fibre by polyimide fiber and be layed in that this base cloth layer is outer, interior two rear flank are closed thorn and formed.
Aforementioned a kind of mixing needled filtering felt, the polyimide fiber in its outer adhesion layer and the interior adhesion layer and the part by weight of polytetrafluoroethylene fibre are 10%-50%: 90%-50%.
The experiment proved that the mixing needled filtering felt of said structure has the characteristics of high temperature resistant, anti-high humidity, corrosion resistance and good, and the filtering accuracy height, filtrate pressure reduction is little, and spinning property aborning is good, can control smoke emissioning concentration less than 30mg/Nm
3, can control the discharging of incineration treatment of garbage tail gas De bioxin and be less than or equal to 0.1Ng-TEQ/Nm

Description of drawings
Fig. 1 is a cross section structure schematic diagram of the present utility model.
The specific embodiment
The specific embodiment of the present utility model is described with reference to the accompanying drawings.
A kind of mixing needled filtering felt, with reference to Fig. 1, the outer adhesion layer 1 and the interior adhesion layer 3 that is attached to the base cloth layer inboard that comprise base cloth layer 2 and be attached to the base cloth layer outside, this base cloth layer 2 is weaved the base cloth that forms for the polytetrafluoroethylene (PTFE) long filament, and this outer adhesion layer 1 and interior adhesion layer 3 are mixed with polytetrafluoroethylene fibre by polyimide fiber and be layed in that this base cloth layer is outer, interior two rear flank are closed thorn and formed.The polyimide fiber in its outer adhesion layer 1 and the interior adhesion layer 3 and the part by weight of polytetrafluoroethylene fibre are 10%-50%: 90%-50%.
The preparation method of above-mentioned mixing needled filtering felt is: be woven into base cloth layer 2 with the polytetrafluoroethylene (PTFE) long filament, after again the polytetrafluoroethylene fibre of the polyimide fiber of 10%-50% and 90%-50% evenly being mixed, close with above-mentioned base cloth layer 1 by shredding, combing, lapping and to sting into plain felt, adhesion layer 1 and interior adhesion layer 3 outside base cloth layer 2, outside inboard the formation.With the above-mentioned plain felt that has processed, be processed into fine and close Nomex by main acupuncture, and finalize the design at 230 ℃ through framing shaping machine, shaping time is 4-10 minute, to eliminate the mechanical internal stress that produces in mechanical processing process.Nomex after finalizing the design is carried out grease-proof and waterproof handle, improve the grease-proof and waterproof performance of filtrate, prevention steam dewfall on filtrate.At last Nomex is singed, calendering handles, the thickness of control filtrate, Air permenbility are to guarantee good deashing property.
Total grammes per square metre of above-mentioned needled filtering felt is controlled at 500-800g/m
2
Above-mentioned only is the specific embodiment of the present utility model, but design concept of the present utility model is not limited thereto, and allly utilizes this design that the utility model is carried out the change of unsubstantiality, all should belong to the behavior of invading the utility model protection domain.
