General in the process of smoke gas treatment, high-temperature flue gas directly enters the phenomenon that the steam condensation can occur in the situation of reduces heat after deduster, has the stickums such as a large amount of mist of oils, trickle floccule in the flue gas of discharging in some special operation condition and exists., no matter be that water or the existence of oily matter all can cause the paste bag of filter bag, the problem that hardens and stop up, cause the pressure reduction of deashing difficulty, increasing dust pelletizing system.Therefore, this type high temp, moisture, oil-contg. smoke are had higher requirement in the selection of filtrate.
At present, common continuous operation temperature of refusing the grease proofing filtrate of water is 120-130 ℃, non-refractory, if operating on for a long time continuously temperature surpasses under 130 ℃ of environment, its strength loss is large, and produces very large contraction, and the size of filter bag is changed, not only affect the dust removal and filtration effect, more change jobs also for later stage of filter bag and brought great inconvenience; Even select PPS, P84, filtrate that these Costco Wholesales of PTFE are relatively high also can only meet the requirement of this type of operating mode to temperature, moisture and oily matter in solution flue gas that can not be perfect are attached on filter bag, and the paste bag that causes, problem hardens.Therefore be badly in need of the filtration problem that a kind of practicality and novel filtrate product with strong points, that Costco Wholesale is relatively low solve present high temperature, high humidity, high burn into oiliness flue gas.
The utility model content
The purpose of this utility model is to provide the special-purpose filtrate of a kind of high-temperature oil resistance GY-1.Filter material surface after dipping and high temperature calendering are processed is Paint Gloss, and splendid chemical stability is arranged, and not aging, hydrophobic is grease proofing again, make to be trapped in surperficial dust and to be easy to peel off, and has stopped the problem that dust hardens and stops up filtrate.Carry out after shredding, mixing, combing again the operation of blending acupuncture by different fibrous materials and combine chemistry and the physical property of different fibers, intensity and the surface abrasion resistance of felt body have been promoted, but also improved the wherein pliability of glass, make its folding resistance stronger, also make the resistance to elevated temperatures of polyster fibre also be greatly improved and improve; Through calendering, singe, thermal finalization, the impregnating operation felt body longer service life after processing.
The technical solution of the utility model is as follows:
A whole set of material mainly comprises: high temperature calendering layer (1), and the grease proofing water microporous barrier of refusing that adopts that the high temperature bright mode forms anchors at GY and meets on knoisphere (2); GY meets knoisphere (2), is the mixed layer body that adopts take polyster fibre, glass fibre, P84 fiber as main formation; Base cloth layer (3) is the layer body that adopts glass fibre to form; GY adhesion layer (4) is the mixed layer body that adopts take polyster fibre, glass fibre, PPS fiber as main formation.
GY meets knoisphere (2) and is covered on base cloth layer (3), base cloth layer (3) is covered on GY adhesion layer (4), GY meets knoisphere (2) and is covered in by closing on nematophore that base cloth layer (3), GY adhesion layer (4) form, then by the acupuncture complex method, links reinforcing.
Three layers of body gross weight that described GY meets after knoisphere (2), base cloth layer (3), GY adhesion layer (4) interfix are 550g/m 2
Described GY meets knoisphere (2) and is respectively the mixed layer body that the PPS fiber of glass fibre, the 2.5D * 60mm of polyster fibre, the 5D * 60mm of 2.8D * 60mm forms, and grammes per square metre is 100g/m 2
Described base cloth layer (3) is the textle layers body that 5D * 60mm glass fibre forms, and grammes per square metre is 300g/m 2
Described GY adhesion layer (4) is respectively the mixed layer body that the PPS fiber of glass fibre, the 2D * 60mm of polyster fibre, the 5D * 60mm of 2.5D * 60mm forms, and grammes per square metre is 150g/m 2
The utility model technology has following advantage:
1. be applicable to the improvement of high temperature, high humidity, high burn into oiliness flue gas operating mode;
2. be furnished with a certain proportion of water oil-proofing agent of refusing in the PTFE maceration extract, make filtrate have very high hydrophobicity and grease proofness, the dust that touches filtrate can come off very soon, has solved the problem that the oiliness dust hardens and stops up filtrate;
3. after blending, impregnation process, the pliability of filtrate, tensile strength, wearability and decay resistance are significantly improved;
4. adopt the highlighted calendering technique of high temperature to substitute conventional coating technique, mixed the grease proofing filter material surface of refusing the water microporous barrier more smooth, more hydrophobic, more grease proofing, filtering accuracy is higher, reduced the gathering of dust; Make the dust of filtration be easy to remove from the film surface, ash-removal effect is good, the cycle is long, thereby has reduced operating cost the service life of having improved filtrate;
5., take glass fibre, polyster fibre as main base-material, improved the pliability of glass fibre and the resistance to elevated temperatures of polyster fibre after mixing by adding PPS, P84, PTFE fiber, and greatly reduced cost.
