Abstract
The utility model relates to a kind of diaphragm seal, is specifically related to a kind of friction-type self compensation double density mounting.This friction-type self compensation double density mounting, comprise gusset, soft seal plate, hard sealing plate and pressing plate, soft seal plate is provided with outside described gusset, hard sealing plate is provided with outside soft seal plate, pressing plate is provided with outside hard sealing plate, described gusset, soft seal plate, hard sealing plate are fixedly connected with by fastening bolt with pressing plate, and described soft seal plate upper end and fanning strip bottom surface touch.Its beneficial effect is: a kind of friction-type self compensation of the utility model double density mounting has: 1) the Retrofit of Air Preheater Seal technology of domestic and international advanced level; 2) be to other any seal form original supplement, improve; 3) the low and stable for extended periods of time of air leak rate of air curtain; 4) regular maintenance, maintenance workload reduce greatly; 5) energy-saving and cost-reducing minimizing cost of electricity-generating, economic benefit is obvious, regains investment for trnasforming urban land in a short time; 6) safe and reliable to operation.
Description
Technical field
The utility model relates to a kind of diaphragm seal, is specifically related to a kind of friction-type self compensation double density mounting.
Background technology
It is 36 or 48 points of chamber structures that air preheater is generally rotor, and conventional seals version is single; Sealing system was the fixed or tuneable architecture of fanning strip originally, leaked out for maximum when the distortion of hot mushroom occurs air preheater rotor in unit operation.To come into operation situation from the air preheater of domestic unit, not good, that air leak rate of air curtain the is high main cause of air preheater operational factor performance is exactly that the project organization of triaxial forces sensor device is unreasonable.
Due to the rigid wearing and tearing occurred unit equipment running time cause the high reason of air preheater air leakage rate have following some:
1) triaxial forces sensor gap causes wearing clearance increase rear without self compensation means because running;
2) after there are wearing and tearing in radial, axial seal sheet, especially hot junction radial outside elastic packing occurred that inefficacy comes off and cause cold wind to invade flue gas storehouse;
3) part heat exchange element damages because of corrugated sheet, forms larger space and becomes so-called smoke corridor, and flue gas flow rate is very fast, and heat transfer effect is low, can be reflected in that pressure reduction is less, exhaust gas temperature is higher.
Utility model content
The utility model is in order to make up the defect of prior art, and provide and a kind of energy-saving and cost-reducing reduce cost of electricity-generating, economic benefit is obvious, the low and friction-type self compensation double density mounting of stable for extended periods of time of air leak rate of air curtain.
The utility model is achieved by the following technical solution:
A kind of friction-type self compensation double density mounting, comprise gusset, soft seal plate, hard sealing plate and pressing plate, soft seal plate is provided with outside described gusset, hard sealing plate is provided with outside soft seal plate, pressing plate is provided with outside hard sealing plate, described gusset, soft seal plate, hard sealing plate are fixedly connected with by fastening bolt with pressing plate, and described soft seal plate upper end and fanning strip bottom surface touch.
Further, described soft seal plate is corrosion resistant plate, and soft seal plate upper end becomes the turnover of 160-170 degree angle to gusset side.
Further, described hard sealing plate steps on steel plate for examining, and hard sealing plate upper end becomes the turnover of 160-170 degree angle to soft seal plate side.
The beneficial effects of the utility model are: a kind of friction-type self compensation of the utility model double density mounting has: 1) the Retrofit of Air Preheater Seal technology of domestic and international advanced level; 2) be to other any seal form original supplement, improve; 3) the low and stable for extended periods of time of air leak rate of air curtain; 4) regular maintenance, maintenance workload reduce greatly; 5) energy-saving and cost-reducing minimizing cost of electricity-generating, economic benefit is obvious, regains investment for trnasforming urban land in a short time; 6) safe and reliable to operation.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described.
Accompanying drawing 1 is structural representation of the present utility model.
In figure, 1 gusset, 2 soft seal plates, 3 hard sealing plates, 4 pressing plates, 5 fastening bolts, 6 fanning strips.
Detailed description of the invention
Accompanying drawing 1 is a kind of specific embodiment of the present utility model.A kind of friction-type self compensation of this utility model double density mounting, comprise gusset 1, soft seal plate 2, hard sealing plate 3 and pressing plate 4, soft seal plate 2 is provided with outside described gusset 1, hard sealing plate 3 is provided with outside soft seal plate 2, pressing plate 4 is provided with outside hard sealing plate 3, described gusset 1, soft seal plate 2, hard sealing plate 3 are fixedly connected with by fastening bolt 5 with pressing plate 4, and described soft seal plate 2 upper end and fanning strip 6 bottom surface touch.
Further, described soft seal plate 2 is corrosion resistant plate, and soft seal plate 2 upper end becomes the turnover of 160-170 degree angle to gusset 1 side.
Further, described hard sealing plate 3 steps on steel plate for examining, and hard sealing plate 3 upper end becomes the turnover of 160-170 degree angle to soft seal plate 2 side.
The utility model is not limited to above-mentioned embodiment, anyone should learn make under enlightenment of the present utility model with the utility model, there is identical or close technical scheme, all fall within protection domain of the present utility model.
Technology, shape, structure part that the utility model is not described in detail are known technology.
