The utility model discloses a coating structure of suture department of compound high temperature resistant filter bag, at the suture department coating one deck silica gel coat of filter bag, filled silica filling layer in the pinhole of the suture department of filter bag covers the pinhole that spills cruelly to the shutoff strengthens its dustproof effect in the pinhole.
Description
Technical field
The utility model relates to a kind of coated structure of suture place of complex fire resistant filter bag.
Background technology
Based on the national requirements of current low emission, increasing application operating mode needs to be emitted on below 5mg, namely our usually said near-zero release, and the control of PM2.5 is also further strict.Conventional filter bag processing is only the adjustment in filtrate material, often ignores the problem in filter bag processing.Usually the selection of filter bag body processing at present has hot melt and suture method, and hot melt is only for the fiber with fusing point, and suture rule can meet all materials.But often there is pinprick on pin hole in suture method, the fine dusts when dust enters deduster on the one hand, especially PM2.5 dust can penetrate pin hole and be discharged into air, high pressure gas expansion filter bag on the other hand in deashing process, also easily from pin hole, muffin to be destroyed, thus fine dust is discharged in air.
Have at present and use overlay film series products to bond at pin hole place, wish to avoid dust to discharge from pin hole, but due to coal-burning boiler use ash content of coal higher, major part coal in siliceous, calcium, the compound of magnesium etc. is more, dust has extremely strong abrasion, PTFE film thickness, usually less than 1 μm, under the effect of high flux air-flow, is very easy to gall thus cause the effect of shutoff pin hole to be lost efficacy.。
Utility model content
The purpose of this utility model is the defect overcoming prior art, provides a kind of coated structure of suture place of complex fire resistant filter bag, and shutoff in pin hole, and hides the pin hole cruelly spilt, and strengthens its dust-proof effect, avoids dust to discharge from pin hole.
The technical scheme realizing above-mentioned purpose is: a kind of coated structure of suture place of complex fire resistant filter bag, described complex fire resistant filter bag comprises superfine fibre layer, the first blended layer, PTFE base cloth layer and the second blended layer from outside to inside successively, described first blended layer and the second blended layer are PPS fiber and PTFE fiber blend layer, the bag body of described complex fire resistant filter bag adopts suture method processing, described coated structure comprises silica gel coat and silicone filler layer, wherein:
Described silica gel coat is coated in the outside at the suture place of described complex fire resistant filter bag, and the peel strength of described silica gel coat is greater than 5kgf/mm, and the coating thickness of described silica gel coat is at 0.02mm ~ 0.04mm;
Described silicone filler layer is filled in the pin hole at the suture place of described complex fire resistant filter bag, and the thickness that described silicone filler layer is filled in pin hole is greater than 0.01mm.
The coated structure at the suture place of above-mentioned a kind of complex fire resistant filter bag, wherein, described silica gel coat and silicone filler layer all select the high temperature resistant silica gel material containing ferrous oxide.
The coated structure at the suture place of above-mentioned a kind of complex fire resistant filter bag, wherein, described silica gel coat contacts with described silicone filler layer and arranges.
The coated structure at the suture place of above-mentioned a kind of complex fire resistant filter bag, wherein, the width of described silica gel coat is greater than the width at the suture place of described complex fire resistant filter bag.
The coated structure at the suture place of complex fire resistant filter bag of the present utility model, compared with prior art, at the outside coating silica gel coat at the suture place of complex fire resistant filter bag, filling gel packed layer in the pin hole at the suture place of described complex fire resistant filter bag, shutoff is in pin hole, and hide the pin hole cruelly spilt, strengthen its dust-proof effect, dust is avoided to discharge from pin hole, and when after the abrasion of silica gel coat, the silicone filler layer of shutoff in pin hole can avoid dust to discharge from pin hole further.
Accompanying drawing explanation
Fig. 1 is the structural representation of complex fire resistant filter bag;
Fig. 2 is the structural representation of the coated structure at the suture place of complex fire resistant filter bag of the present utility model.
Detailed description of the invention
In order to make those skilled in the art can understand the technical solution of the utility model better, below in conjunction with accompanying drawing, its detailed description of the invention is described in detail:
Refer to Fig. 1, most preferred embodiment of the present utility model, complex fire resistant filter bag comprises superfine fibre layer 1, first blended layer 2, PTFE base cloth layer 3 and the second blended layer 4 from outside to inside successively, first blended layer 2 and the second blended layer 4 are PPS fiber and PTFE fiber blend layer, and the bag body of complex fire resistant filter bag adopts suture method processing.
Refer to Fig. 2, a kind of coated structure of suture place of complex fire resistant filter bag comprises silica gel coat and silicone filler layer, silica gel coat 10 is coated in the outside at the suture place 5 of complex fire resistant filter bag, the peel strength of silica gel coat 10 is greater than 5kgf/mm, and the coating thickness of silica gel coat 10 is at 0.02mm ~ 0.04mm; The width w1 of silica gel coat 10 is greater than the width of the suture place w2 of complex fire resistant filter bag.Silicone filler layer is filled in the pin hole 6 at the suture place of complex fire resistant filter bag, and the thickness that silicone filler layer is filled in pin hole is greater than 0.01mm.
Silica gel coat 10 and silicone filler layer all select the high temperature resistant silica gel material containing ferrous oxide.Silica gel coat 10 contacts with silicone filler layer and arranges.
In sum, the coated structure at the suture place of complex fire resistant filter bag of the present utility model, at the outside coating silica gel coat 10 at the suture place 5 of complex fire resistant filter bag, filling gel packed layer in the pin hole 6 at the suture place of complex fire resistant filter bag, shutoff is in pin hole 6, and hide the pin hole cruelly spilt, strengthen its dust-proof effect, dust is avoided to discharge from pin hole, and after silica gel coat 10 is denuded, the silicone filler layer of shutoff in pin hole can avoid dust to discharge from pin hole further.
Those of ordinary skill in the art will be appreciated that, above embodiment is only used to the utility model is described, and be not used as restriction of the present utility model, as long as in spirit of the present utility model, all will drop in Claims scope of the present utility model the change of the above embodiment, modification.
