Abstract
The utility model discloses a brown coal-gas producer, which comprises the furnace and combustion device, wherein the furnace jacket is provided outside the internal furnace which equipped with a conical oxidation at its lower part. An air-supply line is provided on the furnace jacket of the oxidation, which its furnace jacket is forming a wind volume with the upper furnace jacket. The conical oxidation of the internal furnace is provided with distributed air-supply lines all around. The water leg is provided between furnace jacket and the internal furnace, and the oblique admission air pipe is provided in the middle of the internal furnace. The utility model as a brown coal-gas producer can solve the problem that the thermal stability of inferior fuel poor thermal stability lead the adverse gasification, increasing the temperature of the furnace, making the soft coal with high volatilization and low heat endurance and gasify in the furnace in fixed bed with the air as the gasifying agents. It enlarges the using of coal, and enhances the gasification, gasification efficiency and gas heating value, and it is a brown coal-gas gasification device with high efficiency.
Description
Technical field
The utility model relates to a kind of brown coal producer gas generator, especially can the young brown coal that fugitive constituent is higher be gasified totally into the brown coal producer gas generator of high-quality coal gas.
Background technology
At present, known is the fixed bed coal gas producer of vaporized chemical with the air, and its air is to enter from furnace bottom, after obtaining preheating by ash bed top, enter straight-cylindrical zone of oxidation burning coal charge through grate, the slag of generation is entered in the cinder tank by grate, regularly draws out.Be advanced into reducing zone on the carbonic acid gas high-temperature gas that produces, here carbon dioxide reduction becomes carbon monoxide (coal gas), be advanced into the destructive distillation layer in the continuation, heat is passed to fuel, make fuel produce retort process, the destructive distillation gas and the coal gas that produce are together up, enter the drying layer of fuel, and the water vapor that has produced in drying layer is drawn body of heater from the fairlead on drying layer top in the lump.
This furnace type structure high-quality coal that fugitive constituent is lower, moisture is less that can only gasify, as: coke, hard coal etc., for the higher bituminous coal of volatile content, particularly young brown coal, when in this type of furnace, gasifying, the coal gas that produces in the water vapor that is produced in coal tar mist of oil that fugitive constituent produces in the destructive distillation layer and the drying layer and the reducing zone together mixes the back when the coal gas fairlead is discharged body of heater, temperature descends and condense into gluey coal tar settling immediately in pipeline, block pipeline, cause system normally to move, gasification weakens or ends.Straight-cylindrical oxidation panel stove-shaped structure easily makes the coal of poor heat stability produce the bridging phenomenon simultaneously, and fuel is normally gasified.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned defective, a kind of brown coal producer gas generator of novel furnace type structure is provided, this furnace type structure can not only solve the factor of the unfavorable gasification of inferior fuel poor heat stability smoothly, has further improved gasification intensity, gasification efficiency and caloric power of gas.
The technical scheme that the utility model adopted is: the brown coal producer gas generator comprises body of heater and combustion unit, it is characterized in that in the body of heater shell it being flue, the flue bottom is conical oxidation panel, on the body of heater shell of this section, be provided with blast pipe, and form the wind chamber between the body of heater shell of this section and the body of heater shell on top, the conical oxidation panel of flue is provided with the uniform air intake arm of periphery, is water jacket between body of heater shell and the flue, is provided with the oblique tracheae (mouth) of getting of coal gas at the flue middle part.
Above-described coal gas is oblique gets the setting of the horizontal ring-type multiple spot of tracheae, and is designed to coal gas to be got tracheae and water jacket separates sleeve structure.
The utility model brown coal producer gas generator is designed to the taper zone of oxidation of a up big and down small peripheral air intake with oxidation panel, not only is beneficial to and uses the relatively poor coal of thermostability, and the tuyere zone air intake is concentrated simultaneously, easily forms the high-temperature zone, is beneficial to burnouting of fuel.Be designed to a water jacket between the outer wall of stove and the inner bag, can play the recovery heat, improve the effect of body of heater overall thermal efficiency and protection furnace internal-lining.The oblique reducing zone top of tracheae in flue conversion zone (comprising oxidation panel and reducing zone) of getting of coal gas, can directly the coal gas that produces in the reducing zone be taken away, and be designed to sleeve structure, coal gas is got tracheae and water jacket separates, avoid the water in the chuck that temperature of exit gas is reduced, the colloidal of freeze-outing coal tar.
Brown coal producer gas generator of the present utility model can not only solve the factor of unfavorable gasification such as inferior fuel poor heat stability smoothly, and can improve furnace temperature, contained humidity in the coal can also be evaporated simultaneously, carries out thermolysis in the high-temperature zone.Make that to contain fugitive constituent higher, the bituminous coal that thermostability is relatively poor, particularly young brown coal can gasify in the fixed-bed gasification furnace that with the air is vaporized chemical, so not only enlarged the use coal, further improved gasification intensity, gasification efficiency and caloric power of gas, and made the caloric power of gas that is produced by 4600kJ/Nm
3Bring up to 5400kJ/Nm
3, gasification intensity is by 125kg/m
2H improves 210kg/m
2H, gasification efficiency reaches 77%, is a kind of equipment of brown coal hydrogasification efficiently.
Description of drawings
Fig. 1 is a brown coal producer gas generator structural representation of the present utility model.
Among the figure: 1-fire grate, 2-blast pipe, 3-air intake arm, 4-wind chamber, 5-taper oxidation panel, the oblique air hatch of 6-, the 7-water jacket, the 8-flue, 9-steam diffuses mouth, 10-feed opening, 11-throat, 12-water level gauge, the 13-hand hole, 14-stove pin, 15-ash output hole, 16-body of heater shell, 17-body of heater shell.
Embodiment
As shown in Figure 1: brown coal producer gas generator of the present utility model comprises body of heater and combustion unit, it in the body of heater shell 16 flue 8, the flue bottom is conical oxidation panel 5, on the body of heater shell 17 of this section, be provided with blast pipe 2, and form wind chamber 4 between the body of heater shell 17 of this section and the body of heater shell 16 on top, the conical oxidation panel of flue is provided with the uniform air intake arm 3 of periphery, is water jacket 7 between body of heater shell and the flue, is provided with the oblique tracheae (mouth) 6 of getting of coal gas at the flue middle part.
During work, air enters wind chamber 4 by blast pipe 2, enters burning coal in the taper oxidation panel 5 by air intake arm 3 then, when coal is heated on zone of oxidation top, and the coal fragmentation of less stable, smaller volume enters the zone of oxidation burning smoothly.After the charcoal burning in the taper zone of oxidation, the slag that is produced falls into cinder tank by fire grate 1, and the high temperature CO that produces
