Description
Technical field
The utility model relates to a kind of boiler, relates to a kind of coal-burning boiler of normal pressure environmental protection specifically.
Background technology
Coal-burning boiler is that a kind of common coal that utilizes provides the device of hot water for people as the energy.The kind of coal-burning boiler is more in the market, discharge flue is generally straight way or horizontal bend, the speed of flue gas in flue reduces slower, being unfavorable for that imperfect combustion composition in the flue gas fully burns also is unfavorable for the dust in flue gas landing, thereby reduced the thermal efficiency of boiler, the dustiness in the flue gas of discharge and to contain the cigarette amount also higher.
Summary of the invention
The purpose of this utility model just is to overcome above-mentioned deficiency a kind of smokeless and dust free countercurrent heat pipes coal-burning boiler is provided, and has solved in the flue gas dustiness and has contained the technical problem that the cigarette amount is big, the thermal efficiency is low.
Technical problem of the present utility model can be achieved through the following technical solutions:
A kind of smokeless and dust free countercurrent heat pipes coal-burning boiler, comprise body of heater, establish burner hearth in the body of heater, furnace body outer wall and inboard wall of burner hearth form the water tank of boiler, roof of the furnace is established chimney, fire grate is established in the bottom, establish coal feed point on the body of heater, coal feed point extend in the burner hearth, and the hot water mouth is established on furnace body outer wall top, and cold water outlet is established in the furnace body outer wall bottom, parallel first damper and second damper of being provided with in burner hearth, establish gas exit on the first damper top, establish exhanst gas outlet in the second damper bottom, first damper and second damper constitute after-burner, second damper and inboard wall of burner hearth form flue, chimney is located at the roof of the furnace away from coal feed point, also is provided with grey cinder notch on the body of heater of fire grate bottom, and the area of after-burner is greater than the area of flue.
Above-mentioned smokeless and dust free countercurrent heat pipes coal-burning boiler also is provided with air inlet below coal feed point, also be provided with volume damper on air inlet, can regulate fire box temperature by regulating air quantity.
Above-mentioned smokeless and dust free countercurrent heat pipes coal-burning boiler is provided with hot-water line in after-burner, hot-water line is connected with water tank.
Above-mentioned smokeless and dust free countercurrent heat pipes coal-burning boiler, hot-water line is arranged on the top of after-burner.
Above-mentioned smokeless and dust free countercurrent heat pipes coal-burning boiler all is provided with hot-water line at the top and the middle part of after-burner.
Above-mentioned smokeless and dust free countercurrent heat pipes coal-burning boiler is provided with dust-exhausting port in the bottom of after-burner, and the dedusting mouth is provided with the cover plate of band handle.
The utility model is provided with the area of the area of after-burner greater than flue in burner hearth, in the combustion chamber imperfect combustion coal smoke through gas exit to after-burner, speed reduces rapidly, under the effect of baffle plate, change direction again, underspeed once more, thereby increase the time of coal smoke in the after-burner stop, make the clean-burning while of imperfect combustion coal smoke, middle dust in the flue gas lands under the self gravitation effect, entering flue through exhanst gas outlet then discharges, because after-burner is located in the burner hearth, temperature is higher in the burner hearth, the coal smoke that comes out in the combustion chamber at high temperature can fully burn through after-burner imperfect combustion composition in dedusting, thereby improves the thermal efficiency.The dust content that the utility model is discharged and to contain the cigarette amount little, thermal efficiency height, simple in structure.After tested, the gas smoke content of the utility model discharge is 25mg/m
3, be significantly less than the dust emission standard 100-150mg/m that national like product is stipulated
3, also lower than the discharge standard of combustion of natural gas.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
A kind of as shown in drawings smokeless and dust free countercurrent heat pipes coal-burning boiler, comprise body of heater 1, establish burner hearth 4 in the body of heater, furnace body outer wall and inboard wall of burner hearth form the water tank of boiler, roof of the furnace is established chimney 7, fire grate 5 is established in the bottom, establish coal feed point 2 on the body of heater, coal feed point extend in the burner hearth, hot water mouth 9 is established on furnace body outer wall top, cold water outlet 13 is established in the furnace body outer wall bottom, parallel first damper and second damper 11 of being provided with in burner hearth, establish gas exit 10 on first damper, 15 tops, establish exhanst gas outlet 12 in the second damper bottom, first damper 15 and second damper 11 constitute after-burner, second damper 11 and inboard wall of burner hearth form flue, chimney 7 is located at the roof of the furnace away from coal feed point 2, on the body of heater of fire grate bottom, also be provided with grey cinder notch 6, the area of after-burner is greater than the area of flue, below coal feed point, also be provided with air inlet 3, volume damper can be installed at the air inlet place, logical control valve is regulated intake, thereby crosses the effect of control burner hearth room temperature, is provided with hot-water line 14 in after-burner, hot-water line is connected with water tank, hot-water line is arranged at top of establishing after-burner and middle part, the instant heating water pipe is arranged in the top and the middle part of after-burner, is provided with dust-exhausting port 8 in the bottom of after-burner, the dedusting mouth is provided with the cover plate of band handle, can regularly clear up the dust in the after-burner.
