Abstract
The utility model relates to an oblique type fire tube boiler capable of rapidly discharging dirt, which belongs to heat energy converting equipment. The utility model solves the disadvantage of hindered dirt discharge of the existing vertical type and horizontal type fire tube boilers. A boiler barrel of the fire tube boiler is obliquely arranged, and no horizontal surface exists in the boiler barrel. Dirt in the water, which can be centralized to the lowest point of the bottom inside the boiler barrel, are rapidly discharged by a dirt discharging pipe which is arranged at the lowest point. A partition wall which plays the role of heat insulating protection to the bottom of the boiler barrel and to the dirt discharging pipe is arranged between a burnout chamber and a boiler hearth which is positioned at the outer bottom of the boiler barrel.
Description
Affiliated technical field
The utility model belongs to thermal power transfer equipment, specially refers to a kind of quick blowdown inclined multitubular boiler.
Background technology
In the prior art, multitubular boiler has two kinds of forms, and drum vertically is placed as vertical fire tube boiler, and the drum horizontal positioned is a horizontal tubular boiler; Drum is made up of a cylindrical shell, two flat tube sheets of circle and Duo Gen fire tube.
During boiler operatiopn, flame flows in fire tube, and water is static relatively and be heated outside pipe.Dirt precipitates because of static in the water, because of heating concentrates, finally is deposited on the drum inner bottom part, is discharged by the blow-off pipe that is contained in the bottom.Cause that for keeping from heat obstruction in the pipe, blow-off pipe are contained in the adiabatic place of drum outer bottom one end or edge.
In the vertical fire tube boiler, the drum inner bottom part is the flat tube sheet of horizontal positioned, on have many fire tubes vertical; Dirt deposition is on the flat tube sheet, between fire tube and the fire tube in the water, and the blow-off pipe that is positioned at flat tube sheet edge can't be discharged dirt.In the horizontal tubular boiler, the drum inner bottom part is circular arc, and lowest part is a horizontal line; Along with increasing of deposition dirt, horizontal line becomes horizontal plane gradually, and the blow-off pipe that is positioned at bottom one end is difficult to dirt is drained.
Summary of the invention
In order to overcome existing vertical and horizontal two kinds of not smooth defectives of the horizontal blowdown of multitubular boiler, the utility model provides a kind of quick blowdown inclined multitubular boiler, and it focuses on the bottom minimum point with the dirt in the drum, is discharged by blow-off pipe, not only blowdown is quick, and blowdown is clean.
The technical solution adopted in the utility model is: the angle of drum inclination with assembling, and be placed on the boiler steelframe and fix, like this, minimum point is not a plane in the drum, but the orthogonal vertical point of cylindrical shell and circular flat tube sheet.Blow-off pipe is punished two kinds of installation forms at the point that hangs down: for the unpressurized hot water boiler, blow-off pipe is contained in the drum outer bottom, and suction inlet does not insert in the drum up; To concentrate near the dirt of the point that hangs down by gravity discharges.For steam boiler, the pressure hot-water boiler is arranged because the some place's perforate of hanging down is dangerous, blow-off pipe is inserted in the drum by the side, near the point that hangs down, suction inlet down, by the pressure in the drum, near the dirt that will concentrate on the point that hangs down is discharged.Because dirt concentrates near the point that hangs down in the drum, can not be heated near the point so hang down, and the outer blow-off pipe of drum can not be heated, so the utility model minimum point outside drum, near the partition wall that setting has certain thickness together, makes with heat-insulating material below promptly hanging down the point, blow-off pipe is wrapping up tightly within the walls, is caused outside the boiler by the partition wall side; Partition wall separates combustion chamber and secondary furnace, and the centre has through hole that two Room are linked to each other.
The utility model has the advantages that: drum is in tilted layout, and does not have horizontal plane in the drum, and dirt focuses on minimum point in the drum from all directions in the water, is discharged fast by blow-off pipe.Partition wall concentrates place and blow-off pipe that the insulated heat effect is arranged to the boiler drum bottom dirt.
Description of drawings
The utility model will be further described below in conjunction with accompanying drawing:
Accompanying drawing 1 is a kind of cutaway view of quick blowdown inclined multitubular boiler,
Accompanying drawing 2 is detailed structure view that dirt is concentrated the A-A of place section in the accompanying drawing 1.
Among the figure: 1. cylindrical shell; 2. fire tube; 3. partition wall; 4. combustion chamber; 5. secondary furnace; 6. down blow pipe; 7. go up blow-off pipe; 8. circular flat tube sheet; 9. water inlet pipe; 10. hot water (steam) is managed; 11. steelframe.
The specific embodiment
In the accompanying drawing, flame from the combustion chamber (4) pass partition wall (3), the water in secondary furnace of flowing through (5) and fire tube (2) and the drum carries out heat exchange, discharges outside the boiler then.Cold water is entered in the drum by water inlet pipe (9), by fire tube (2) heating or vaporization, outside hot water (steam) pipe (10) is discharged boiler.Because a drum angle of inclination also is fixed on the steelframe (11), therefore, cylindrical shell (1), circular flat tube sheet (8) and the fire tube (2) of forming drum all tilt, there is not horizontal plane in the drum, dirt can only be concentrated and be deposited to minimum point in the drum, be positioned near the suction inlet of blow-off pipe (7) or down blow pipe (6) in the water, and suction inlet is flooded; Opening blow-off pipe just can utilize pot inner pressure or gravity that dirt is discharged outside the boiler fast.
Claims (2)
1, a kind of quick blowdown inclined multitubular boiler does not have horizontal plane in the drum, and lowest part is the orthogonal vertical point of shell and tube sheet, it is characterized in that: angle of drum inclination is fixed on the boiler steelframe.
2, quick blowdown inclined multitubular boiler according to claim 1 is characterized in that: the outer minimum point of drum is positioned on the adiabatic partition wall.
