Description
Technical field
The present invention relates to a kind of sealing brush, be specifically related to a kind of air preheater composite seal brush, belong to sealing brush technical field.
Background technology
Heat power plant boiler adapted air preheater generally has two kinds of tubular type and swingings, wherein rotary regenerative air preheater because of compact conformation, characteristics such as floor space is little, the steel consumption amount is little by the large-scale power station extensive use.Because rotary regenerative air preheater adopts the single track Sealing Technology more, adds installation deviation and factors such as long-time running wearing and tearing and thermal deformation, causes the air leak rate of air curtain of unit bigger than normal, it is the ubiquitous problem of station boiler of using this equipment.
Leaking out of rotary regenerative air preheater can be divided into two parts: structure is leaked out (or claiming to carry to leak out) and is directly leaked out.Because air preheater inside is divided into some storehouses lattice, it is inevitably that this structure determines structure to leak out, and generally speaking, the leak out share of the total inleakage of duty gas preheater of this part is less, less than 10%.The form of mainly leaking out of air preheater is for directly leaking out, inevitably there is the gap between the sound of rotary regenerative air preheater, the blast of wind pressure ratio secondary blast and fume side is high a lot of again, under the effect of pressure reduction, wind direction secondary side and fume side are directly leaked and the secondary wind direction fume side is leaked out.Leaking out not only increases the boiler exhaust gas heat loss, and has increased the weight of the equipment cold end corrosion that causes because the cigarette temperature drop is low, has also increased the blower fan power consumption, also can directly influence boiler output because of deficiency in draught when the problem of leaking out is serious.
The rotary regenerative air preheater conventional seals adopts the gapped Sealing Technology of rigidity, keeps a minimum clearance between sound, reaches the minimum of leaking out.Because the mushroom deformation problem of air preheater rotating cylinder, and this distortion constantly changes with the load environment temperature, makes static seal be difficult to reach the gap width an of the best.The gap is too small, easily produces the sound friction between diaphragm seal and the fanning strip, directly threatens the safe operation of equipment; Excesssive gap, the air-heater leakage rate is big, has influenced the economical operation of unit again.
Air preheater brush Sealing Technology is the air preheater flexible sealing technology of newly-developed, and its core component brush silk adopts a high-temperature alloy to make, and the meeting of brush silk freely change angle and cooperates with it when contact with fanning strip, forms a sealing surface.Coefficient of friction between brush silk and the fanning strip is less, and both can not cause rigid damage to fanning strip at flexible contact.The brush silk has good resilience, can restore to the original state rapidly when entering nonclient area, thereby can keep lower air leak rate of air curtain for a long time.The sealing of air preheater brush is rotated jerk value requirement reduction to the both ends of the surface of rotating cylinder and the depth of parallelism, flatness and the rotating cylinder of fanning strip, maintenance duration and workload have been reduced, can also adapt to simultaneously rotating cylinder mushroom deformation in various degree under the different load, make that the air leak rate of air curtain of air preheater can both remain on a reduced levels under arbitrary load.For the air preheater that adopts common rigidity diaphragm seal sealing, its air leak rate of air curtain is 6%-10% when operating mode is good, during poor sealing even reach 20%-30%.Test data shows, adopts the sealing of air preheater brush can be so that its air leak rate of air curtain is reduced to 3%-6%, and is subjected to the influence of load variations less, can keep higher sealing effectiveness for a long time.
Air preheater brush seal operation environment is very abominable, contains gases such as oxysulfide, nitrogen oxide in the high-temperature flue gas, easily forms dew point corrosion at cold junction, is mingled with solid particles such as coal ash simultaneously in the flue gas, constantly washes away sealing device.Consider above factor, simultaneously for reaching better sealing effectiveness, generally install a brush sealing assembly additional in the former diaphragm seal of air preheater position, but not directly change former diaphragm seal, so air preheater rotating cylinder gross weight increases, loading ability of bearing increases, and starting current also can increase thereupon, to the electric part requirement raising of equipment.
Chinese patent ZL 200620113790.5 discloses the rotary regenerative air preheater that has brush sealing, pointed out sealing property that the brush sealing is excellent and with the assembly relation of each parts of air preheater, but not to the specific constructive form explanation of brush sealing.Air preheater equipment is huge, and brush sealing adopts the mode of complete assembly welding to have problems such as welding deformation, thermal stress are big, thus nowadays on the market common air preheater brush seal structure mostly be bolt clamping structure greatly.The whole sealing device complex structure, heavy unusually, starting current increases comparatively obvious.Complicated clamping can not guarantee precision, and production efficiency is also lower.The air preheater brush is sealed under the duty and generally contacts with the fanning strip interference, be subjected to an intermittent impulsive force along direction of rotation inevitably, and constantly in cold and hot medium, circulate, each parts easily produces fatigue damage, firm degree can't guarantee, exists the brush silk to drop, brush hidden danger such as bar comes off.
