Abstract
The utility model discloses a multi-stage heating heat exchanger for coal stoves, which is composed of a chimney water sleeve (2) with a water outlet (1), a stove mouth water sleeve (6), and a stove body water sleeve (8) which are connected in sequence. The utility model is characterized in that a heat collecting pipe (31) is arranged in the chimney water sleeve (2); the chimney water sleeve (2) and the stove body water sleeve (8) are communicated; the upper end and the lower end of the stove mouth water sleeve (6) respectively have a communicating pipe; communicating pipes are respectively communicated with the chimney water sleeve (2) and the stove mouth water sleeve (8); the direction of a water inlet (10) is the tangential direction of the out circle of the stove mouth water sleeve (8). The utility model solves the defects of low heat efficiency and no natural circulation in general heat exchangers. The utility model has the advantages of high efficiency and automatic circulation. The utility model can be widely used in various life coal stoves for heating radiators.
Description
The utility model discloses that a kind of to can be used for common coal-fired life warming stove be the heat exchanger of radiator heat supply.
At present, to install heat exchanger additional be that the radiator heat supply is widely adopted to coal-fired life warming stove.Because the differential water pressures slight drag of heat exchanger itself is big, be difficult to form the circulation of nature water, all adopt water pump pressurization forced circulation.
It is little that invention task of the present utility model provides a kind of water circulation resistance, but the coal stove of the big Natural Circulation of differential water pressures is with multistage heating heat-exchange device.
Technical essential of the present utility model is:
1, adopts body of heater, fire door, three grades of water jackets of chimney.
2, in the chimney water sleeve thermal-collecting tube is installed.
3, adopt two groups of heat collecting sheet designs.
4, the axis of water inlet and furnace water jacket cylindrical are the secant-shaped installation.
The utility model is finished like this: a kind of coal stove comprises the chimney water sleeve of taking the mouth of a river (1) out of (2) that connects successively from top to bottom with multistage heating heat-exchange device, furnace saliva set (6), furnace water jacket (8) three parts constitute, it is characterized in that having installed in the chimney water sleeve (2) thermal-collecting tube (3), link between chimney water sleeve (2) and the furnace water jacket (8), furnace saliva set (6) upper end has cross over pipe (4) and chimney water sleeve (2) to link, the lower end has cross over pipe (7) and furnace water jacket (8) to link, be positioned at the chimney water sleeve (2) at chimney position, be connected and installed with heat collecting sheet (5) between furnace saliva set (6) and the furnace water jacket (8), the axis and furnace water jacket (8) cylindrical that are positioned at the water inlet (10) of furnace water jacket (8) lower end are the secant-shaped installation.
In order to improve the heat exchange benefit, can be at the installed inside heat collecting sheet (9) of furnace water jacket (8).
Cold water was in water inlet enters heat exchanger when the utility model used, and heating is discharged from delivery port at last step by step.Because difference in height is big between importing and exporting, make the water that generation is big in the heat exchanger too poor easily.Because water inlet axis and body of heater water pipe are tangent, reduced the water inlet resistance again.More than several design results make thermal efficiency height of the present utility model, hydraulic pressure is big, forms Natural Circulation, can be widely used in the various life coal stoves.
Figure of description 1 is a structure cutaway view of the present utility model; Accompanying drawing 2 is that the A-A of accompanying drawing 1 is to cutaway view.
Among the figure: 1, delivery port, 2, chimney water sleeve, 3, thermal-collecting tube, 4, cross over pipe, 5, heat collecting sheet, 6, furnace saliva set, 7, cross over pipe, 8, furnace water jacket, 9, heat collecting sheet, 10, water inlet.
An embodiment of the present utility model has adopted the high-strength steel sheet welding to make.Wherein, it is trapezoidal that chimney water sleeve is, and fire door and furnace water jacket are in the form of a ring.
Claims (2)
1, a kind of coal stove comprises the chimney water sleeve of taking the mouth of a river (1) out of (2) that connects successively from top to bottom with multistage heating heat-exchange device, furnace saliva set (6), furnace water jacket (8) three parts constitute, it is characterized in that having installed in the chimney water sleeve (2) thermal-collecting tube (3), link between chimney water sleeve (2) and the furnace water jacket (8), furnace saliva set (6) upper end has cross over pipe (4) and chimney water sleeve (2) to link, the lower end has cross over pipe (7) and furnace water jacket (8) to link, be positioned at the chimney water sleeve (2) at chimney position, be connected and installed with heat collecting sheet (5) between furnace saliva set (6) and the furnace water jacket (8), the axis and furnace water jacket (8) cylindrical that are positioned at the water inlet (10) of furnace water jacket (8) lower end are the secant-shaped installation.
2, according to the described coal stove of claim 1 with multistage heating heat-exchange device, it is characterized in that furnace water jacket (8) installed inside heat collecting sheet (9).
