Description
Technical field
The present invention relates to technical field of heat exchange, more particularly to boiler one kind can be convenient and swift thoroughly clear
The movable tubulation airduct air preheater of ash.
Background technology
The air preheater generally used on boiler at present, it is pre- by air preheating housing, in air
Two ends coordinate the tubulation of solid welding with the tube sheet pore on air preheating housing, divided respectively in hot device housing
The upper and lower flue of air preheating housing upper and lower end is not fixed on and is separately fixed at air preheater
The air channel composition of housing both sides, the caloic flue gas sent out by economizer by air preheater upper flue,
Drawn after tubulation inner chamber, lower flue by air-introduced machine, cold air is by side air channel, air preheater shell
In vivo, boiler air room is entered behind opposite side air channel, the cold air in air preheating housing is laterally rushed
During brush tubulation surface, completion is exchanged with the flue gas heat passed through in tubulation inner chamber, by air preheater shell
Air out is hot-air in vivo, and this tubulation inner chamber is walked and walks air outside flue gas (caloic), tubulation
Air preheater is referred to as smoke pipe air preheater.The caloic flue gas sent out by economizer is pre- by air
Drawn in hot device upper flue, air preheating housing, after lower flue by air-introduced machine, cold air passes through one
Behind crosswind road, tubulation inner chamber, opposite side air channel enter boiler air room, tubulation inner chamber cold air with
Heat exchange is completed by the caloic flue gas in air preheating housing during transversal flow tubulation surface, by arranging
The air that tube cavity comes out is hot-air, and this tubulation inner chamber walks to walk flue gas (caloic) outside air, tubulation
Air preheater be referred to as airduct air preheater.Either smoke pipe air preheater or airduct
Air preheater, is all solid welding on the tube sheet of air preheating housing in structure upper tube array, it is impossible to living
It is dynamic, it is fixed tubulation.In use, smoke pipe air preheat in the caloic flue gas environment containing ash
The tubulation inner chamber of device, the easy dust stratification in tubulation surface of airduct air preheater, Shortcomings are, deashing
Shi Bixu blowing outs, there is the difficulty that deashing time length, labor intensity are big, be unable to mechanization deashing, it is impossible to
Thorough deashing.
The content of the invention
The technical problem to be solved in the present invention is that existing airduct air preheater is solid in structure upper tube array
Fixed pattern tubulation, it is impossible to activity, in tubulation superficial dust, the deashing blowing out existed, deashing is difficult,
Can not thorough deashing deficiency.
In order to solve the above technical problems, the technical solution used in the present invention is that can facilitate there is provided one kind
The movable tubulation airduct air preheater of quick thoroughly deashing, it is by air preheating housing, bolt
It is separately fixed at the upper and lower flue of the air preheating housing upper and lower end, is bolted to side by side
Ventilation blower suction channel on the tube sheet of the air preheating housing side, with air phase ventilating duct, be hinged
Opposite opened button door and tubulation composition on the air preheating housing opposite side tube sheet are fixed on, it is described
The door inner chamber of opposite opened button door forms revolution air compartment, door opposite side and the bottom engaged with the opposite side tube sheet
While there is sealing gasket, it is characterised in that：Hawk and flap pressure regulation air door are also scraped, the tubulation is activity
Formula tubulation, it is described to scrape hawk equidistant parallel distribution in the air preheating housing, with the sky
The forward and backward plate inwall solid welding of air preheater housing, the tubulation respectively with the air preheating housing pipe
Plate and it is described scrape corresponding tubulation mounting hole gap on hawk and coordinate, the tubulation is in the revolution air compartment one
Have handle hole on the wall of side, the flap pressure regulation air door in the mouth end with air phase ventilating duct,
The axle of the flap pressure regulation air door coordinates with the corresponding mounting hole on the wall with air phase ventilating duct, drawn
Described in going out operation handle is connected with one end outside the wall of air phase ventilating duct.
Compared with the prior art the present invention, hawk and the flap pressure regulation air door is scraped described in being designed with；
The tubulation is movable tubulation, can be achieved radial rotating and to slide axially, and its advantage is, energy
In the state of not blowing out, periodically manually or mechanically change operation and match somebody with somebody with the handle hole on the tubulation
The operating mechanism of conjunction, when by the tubulation radial rotating 180 degree angle, cigarette is met on the tubulation surface
Gas direction is changed into back of the body flue gas direction, and the self-cleaning removing tubulation surface area is realized by flue gas backward erosion
Ash；When the axial pull of the tubulation is slided, the tubulation and described scrape between hawk are present along institute
The relative mechanical motion of tubulation axial direction is stated, realizes that mechanical scraping brush type removes the tubulation superficial dust；Clearly
Grey process is convenient, fast, thorough；Avoid blocking flue, it is ensured that heat exchange efficiency.
