Description
Technical field
The utility model relates to the fanning strip autotracker that a kind of bimetal tube drives, and relates to the sealing device of rotary regenerative air preheater rotor and fanning strip specifically, belongs to the heat-exchange apparatus technical field in the unit boiler of thermal power plant.
Background technology
Rotary regenerative air preheater is to utilize the hot flue gas that the coal-burning boiler afterbody is discharged in the thermal power plant, with a kind of heat-exchange device of cold air heating back entering boiler auxiliary combustion, is used widely on the heavy duty boiler in modern times.Rotary regenerative air preheater is owing to rotatable parts are arranged, and is gapped between rotor and fanning strip and rotor and the arc, bigger pressure reduction arranged, the problem that this has just brought air in flue gas, to leak, the problem of promptly leaking out between the air side of preheater and the fume side simultaneously.Leaking out of rotary regenerative air preheater can cause unit heating power operating mode relatively poor, quickens the cold end corrosion process, reduces generatine set heat efficiency, increases the ventilating machinary power consumption, and boiler efficiency is reduced, and then influences the economic benefit of unit overall operation.At present along with the continuous increase of boiler capacity, rotary regenerative air preheater is also more and more big, and this makes problem such as leak out more outstanding.The air leak rate of air curtain of rotary regenerative air preheater general requirement in design is not more than 10%, but practical application much is 20～30%, sometimes even up to 40%.To be rotor with temperature raise the main cause that rotary air preheater air leak is big irregular " mushroom distortion " takes place causes excesssive gap between rotor and the fanning strip promptly so-called " triangle leak out district ".The size of air leak rate of air curtain is to weigh an important indicator of rotary regenerative air preheater technical merit.Solve the rigid Sealing Technology of the general employing of the problem of leaking out at present, promptly, reserve seal clearance in advance by calculating the hot shaping parameter.But because the distortion between rotor and the fanning strip has certain angle, preset clearance can not be too small, can produce clamping stagnation otherwise be in operation, and can make between rotor and the fanning strip and scratch, and influences the normal operation of equipment; And a slot reservation is excessive, can not well seal again, makes hot operating the leaking out will be very big.
The utility model content
The purpose of the utility model is in order to overcome the deficiency of above-mentioned rotary regenerative air preheater sealing state; A kind of rotary regenerative air preheater fanning strip self-checking device is provided, and the fanning strip autotracker that this rotary regenerative air preheater bimetal tube drives has automatic compensation because the problem of the excesssive gap that " the mushroom distortion " of rotary regenerative air preheater rotor causes.
The utility model solves the technical scheme that its technical problem adopted: the utility model comprises bimetal tube retractor device, movable fanning strip up and down and lever beam up and down; The inner and outer pipe of bimetal tube retractor device is processed by two thermal coefficient of expansion different metallic materials, and concrete structure is following:
Its structure is: the outer tube upper end is provided with two parallel last ears; The bottom is provided with base flange plate; The top of base flange plate is provided with can be through the through hole of upper lever beam, monaural in interior pipe top connects through ring flange, and the below connects ear down; Interior monaural and last ears are hinged by hinge one, and following ear is through the power arm end of the hinged upper lever beam of bearing pin; The last fanning strip of rotor top and the following fanning strip of below are made as the fanning strip that can move up and down, and are provided with two pin joints between the narrow end of fanning strip and the crossbeam; Side at preheater crossbeam flue vertically is equipped with bracing frame; Through base flange plate the bimetal tube retractor device is installed on the horizontal plane of bracing frame, bracing frame is provided with locating hole, and the fulcrum hole of upper lever beam and locating hole are hinged by hinge two; The front end of upper lever beam connects through last jockey goes up the wide end of fanning strip; The tail end of upper lever beam connects connecting rod, and connecting rod connects lever beam down, and following lever beam connects fanning strip down through lower connecting device.
The beneficial effect of the utility model is: through this device effectively controlled since rotor that rotor " mushroom distortion " forms and fanning strip between " triangle leak out district ", leakage loss descends significantly, simple in structure, rebuilding construction is implemented easily.
