Description
Technical field
The present invention relates to technical field of heat exchange, more particularly to boiler one kind can convenient and efficient thorough deashing it is movable
Tubulation air hose air preheater.
Background technique
The air preheater generally used on boiler at present, by air preheating housing, in air preheating housing
Both ends cooperate the tubulation of solid welding with the tube sheet pore on air preheating housing respectively, are separately fixed at air preheating housing
The upper and lower flue of upper and lower end and the air duct composition for being separately fixed at air preheating housing two sides, the caloic sent out by economizer
Flue gas is drawn after air preheater upper flue, tubulation inner cavity, lower flue by air-introduced machine, and cold air is by side air duct, sky
In air preheater shell, enter boiler air room behind the air duct of the other side, the cold air transversal flow column in air preheating housing
When pipe surface, completion is exchanged with the flue gas heat passed through in tubulation inner cavity, is heat by the air come out in air preheating housing
Air, this tubulation inner cavity are walked flue gas (caloic), and the air preheater that air is walked outside tubulation is referred to as smoke pipe air preheater.By
Economizer send out caloic flue gas by air preheater upper flue, air preheating housing, after lower flue by air inducing power traction
Out, cold air behind side air duct, tubulation inner cavity, other side air duct enter boiler air room, tubulation inner cavity cold air with
Heat exchange, the sky come out by tubulation inner cavity are completed by the caloic flue gas in air preheating housing when transversal flow tubulation surface
Gas is hot-air, and air is walked in this tubulation inner cavity, and it is pre- that the air preheater that tubulation walks flue gas (caloic) outside is referred to as air hose air
Hot device.Either smoke pipe air preheater or air hose air preheater, are all solid weldings in air preheater in structure upper tube array
It is stiff on the tube sheet of shell, it is fixed tubulation.In use, smoke pipe air in the caloic flue gas environment containing ash
The tubulation inner cavity of preheater, air hose air preheater tubulation surface be easy dust stratification, Shortcomings are, when deashing must blowing out,
There are deashing time length, large labor intensity, the difficulty for being unable to mechanization deashing, it cannot thorough deashing.
Summary of the invention
The technical problem to be solved by the present invention is to, having air hose air preheater in structure upper tube array is fixed tubulation,
Stiff, in tubulation superficial dust, existing deashing blowing out, deashing is difficult, cannot thorough deashing deficiency.
In order to solve the above technical problems, the technical solution used in the present invention is, providing one kind can be convenient and efficient thoroughly clear
The movable tubulation air hose air preheater of ash, it is separately fixed at the air preheater by air preheating housing, bolt
Upper and lower flue, the bolt arranged side by side of shell upper and lower end are fixed on the ventilation blower air draught on the tube sheet of the air preheating housing side
Road, with atmosphere phase ventilating duct, the opposite opened button door and tubulation that are hingedly fixed on the tube sheet of the air preheating housing other side
Composition, the door inner cavity of the opposite opened button door form revolution air compartment, and door opposite side and the bottom edge engaged with the other side tube sheet have
Gasket, it is characterised in that: also scrape hawk and rotating plate pressure regulation air door, the tubulation is movable tubulation, and the hawk of scraping exists
Equidistant parallelly distribute in the air preheating housing, with the forward and backward plate inner wall solid welding of the air preheating housing, the column
Pipe respectively to the air preheating housing tube sheet and described scrape corresponding tubulation mounting hole clearance fit, the tubulation on hawk and exist
Have handle hole on the side wall of described revolution air compartment one end, the rotating plate pressure regulation air door in the mouth end with atmosphere phase ventilating duct,
The axis of the rotating plate pressure regulation air door cooperates with the corresponding mounting hole on the wall with atmosphere phase ventilating duct, draws described and big gas phase
One end outside the wall of ventilating duct is connected with operation handle.
Compared with the prior art the present invention, scrapes hawk and the rotating plate pressure regulation air door described in design has；The tubulation
For movable tubulation, it can be achieved that radial rotating and sliding axially, its advantages are, can be in the state of not blowing out, regular people
The operating mechanism of handle hole cooperation in work or mechanized operation and the tubulation, by the tubulation radial rotating 180
When spending angle, flue gas direction is met on the tubulation surface to be become carrying on the back flue gas direction, realizes self-cleaning removing institute by flue gas backward erosion
State tubulation superficial dust；When sliding the tubulation axial direction pull, the tubulation and described scrape between hawk exist along described
The relative mechanical of tubulation axial direction moves, and realizes that mechanical scraping brush type removes the tubulation superficial dust；Deashing process is convenient, fast,
Thoroughly；Blocking flue is avoided, ensure that heat exchange efficiency.
Detailed description of the invention
Fig. 1 be can convenient and efficient thorough deashing movable tubulation air hose air preheater schematic diagram of main cross-sectional structure；
Fig. 2 be can convenient and efficient thorough deashing movable tubulation air hose air preheater in Fig. 1 A-A to sectional structure
