Abstract
The utility model relates to an arc coal-fired gasification boiler, which is characterized in that an arc-shaped downcomer and an arc-shaped water wall tube are arranged in the boiler; a grate without an ash removing door is provided with an automatic ash discharge device; a motor of the grate is an adjustable intermittent operation motor; a porous gasification burner is arranged between a boiler barrel and the grate; one side of a machine seat is provided with a moment protection speed reducing motor and the adjustable intermittent operation motor, and the other side of the machine seat is provided with a noiselessness fan; a motor of a water pump, an electromagnet, an air inducing motor, an air blowing motor and the motor of the grate are respectively controlled by a circuit of an electric control cabinet which is provided with an automatic/manual switching mechanism. The utility model has the advantages of difficult scaling, small running resistance, high coal combustion efficiency, no smoke, no pollution, simple manufacturing technique and long service life.
Description
The utility model belongs to boiler design and manufacturing technology field.
At present, the boiler that use various places, its water screen tube, down-comer just are being, are falling " eight " font pipe.Shortcoming is: there is " ellipse " phenomenon in the knee of down-comer; Knee wall compression distortion, resistance in service is bigger, and efficient is low, easily fouling; The manufacturing process complexity, service life is short.Simultaneously, the interior arch of this boiler can only play the protection combustion, can not remove black smoke, and environmental issue is big, the solution of need making great efforts.
The purpose of this utility model is that the problem at existing boiler structurally exists provides a kind of employing arc water screen tube and down-comer, has the arc gasification coal-fired boiler of porous type gasification combustor.
The technical solution of the utility model is:
The utility model is because of adopting arc water screen tube and arc down-comer, and coal carries out second-time burning in the porous gasification combustor, so claim the arc gasification coal-fired boiler.
Compare with existing boiler, inventive point of the present utility model is:
1 change existing boiler water-wall tube, down-comer just, " eight " font that falls is arc.With solve the down-comer knee occur oval, resistance in service is big, efficient is low, easy fouling, service life short problem;
The 2 interior arches that change existing boiler are porous gasification combustor (placing drum bottom and fire grate top), so that fire coal reaches second-time burning, with the coal after-flame, flame is by the many pore ejections of gasification combustor, no black smoke, no dust;
3 employings do not have the door of scratching in the ashes, it has the fire grate of automatic ash dropped unit, to solve operating environment free from dust problem;
4 adopt intermittent duty motor and noiselessness blower fans, to improve automaticity and to make the boiler noiselessness that is in operation;
5 adopt the tube-sheet type end socket, and its advantage is not pressurized shape restriction of thickness, and the bloated in advance technology of fire tube is simple, and bridge does not rupture.
Below in conjunction with accompanying drawing planform of the present utility model is done and to be specified
Fig. 1 is the utility model structural representation
Fig. 2 is I of the present utility model-I cutaway view
Fig. 3 is the circuit theory diagrams of electrical control cubicles
The board-like end socket 3-of 1-arc down-comer 2-drum 4-fire tube 5-arc water screen tube 6-next part case 7-porous gasification combustor 8-does not have the adjustable intermittent duty motor of the automatic ash dropped unit 10-of a fire grate 9-force moment protection reductor 11-12-noiselessness blower fan of scratching in the ashes
As shown in the figure, arc down-comer 1, arc water screen tube 5 be pot body part two. By arc down-comer 1, tube-sheet type end socket 2, drum 3, fire tube 4, arc water screen tube 5 and lower Header 6 is through being welded to form a pot body.
Do not have the fire grate 8 of scratching in the ashes and have automatic ash dropped unit 9. This fire grate is through supporting seat and the welding of pot body Be integral. Be bolted on support again.
Drum 3 and nothing are scratched in the ashes porous gasification combustor 7 between the fire grate 8.
One side of support is equipped with force moment protection reductor 10 and adjustable intermittent operation motor 11; Another Side is equipped with noiselessness blower fan 12.
The circuit control of electrical control cubicles divides three groups (seeing Fig. 3).
Pump motor M4It is separately first control group. When leaving water temperature be lower than the upper limit set or It is lower that sensor is passed to the leaving water temperature controller with leaving water temperature in limited time, water pump namely start on request or Stop. Electromagnet T is independent second control group, and it is automatic that its timing adhesive action draws grey mechanism Ash falls. Id-motor M1, blower motor M2With fire grate M3It is the 3rd control group. When return water temperature is lower than the upper limit set or in limited time lower, sensor is passed to the backwater temperature with temperature signal During the degree controller, controller is controlled starting or stoping of the 3rd control group motor.
Automatic/hand switching mechanism in the electrical control cubicles can automatically also can be manual.
Fire grate M in the 3rd control group3Be adjustable intermittent operation motor, speed governing is intermittently delivered coal. Its intermittent duty speed regulation process is:
As fire grate M3Contactor J6Adhesive, speed regulator get electric work, integrated timer IcReset, Q holds output low level, BG3Conducting, silicon controlled toggle work, fire grate running. While BG1Cut-off, BG2Satisfy and close conducting, timer starting of oscillation. When reaching the scheduled time. Timer The upset of Q end is high level, BG3Cut-off, silicon controlled toggle quits work, and motor shuts down. While BG2Cut-off, BG1Satisfy and close conducting. After reaching the scheduled time, timer Q end turns over again Transfer low level to, motor turns round again. The motor real-world operation time was directly proportional with service cycle. When When potentiometer adopted linear potentiometer, motor rotation was continuously adjustable in setting range, and it regulates model Enclose and to be turned round to continuous operation by zero, therefrom can select the desirable speed of delivering coal.
The utility model has the advantages that the decline caliber does not have oval phenomenon, and is less scaling, running resistance Little, long service life. Coal combustion efficient height, there is not problem of environmental pollution in no black coal, makes
Technology is simple.
Embodiment:
Can implement with the relevant explanation processing and manufacturing in the specification by structure shown in the drawings.Key wherein is: adopt arc water screen tube, arc down-comer, porous gasification combustor and the fire grate that does not have scratch in the ashes a fire grate and adjustable intermittent duty.
