Abstract
The utility model relates to a charring furnace, particularly a gas-combustion inner-heating continuous charring furnace. The charring furnace body is a refractory brick-lined steel cylinder, a double bell jar coal charging box is arranged at the top part, and a fire exploring hole and a gas nozzle are arranged at the middle part. The utility model is heated by the self-produced gas, reducing the fuel consumption and the production cost. The utility model has the advantages of simple structure, convenient and flexible operation and is mainly used for producing carbocoal from the new born coal in chemical industry, metallurgy industry, etc. The byproduct low temperature tar can be used for chemical industry, metallurgy and building industry. Except that part of the byproduct gas is used for self heating, the rest can be transmitted outside for industrial and civil use.
Description
The utility model relates to a kind of charring furnace, particularly relates to hot continous way charring furnace in a kind of gas combustion.
Present existing charring furnace generally all is the square box shape body of heater that refractory brick is built by laying bricks or stones.Complex structure, the hand firing is discharged of the coke, and is discontinuous, thermo-efficiency is lower, labour intensity is big, it is bigger to pollute.
The purpose of this utility model provides hot continous way charring furnace in gas a kind of simple in structure, the easy to operate combustion, and the coal pollution of the discharging of the coke is little continuously for it.
The purpose of this utility model is achieved in that body of heater adopts steel cylinder, inner lining refractory block.The top has double belljar to add coal bin, is made up of two coal bins up and down, and it acts under the situation of not blowing out, and continuous coal discharges of the coke.Fix a skirtboard at the top of furnace chamber, can make coal be dispersed in sole and stove center, coal is even under reaching.Be fixed with several fire exploring holes at the middle part of body of heater, along the housing radial equipartition, quantity is decided according to stove internal diameter size, is used for observing coal carbonization situation in the stove.If find fluffy material in the stove, can from fire exploring hole, insert drill rod, handle.In the bottom of fire exploring hole along several gas jets of housing radial equipartition, material supply thermal source in stove continuously, quantity is decided according to stove internal diameter size.This gas jet is a jacketed type, the internal chamber wall of nozzle and outer wall looping air flue, and inlet mouth communicates with annular air channel.Ingress at nozzle is provided with coal gas and air control valve, can adjust the ratio of coal gas and air at any time.After coal gas and air are adjusted by a certain percentage,, produce elevated temperature heat gas and the coal counter current contact that moves down, reach the destructive distillation purpose in the nozzle exit burning.The grate cooling coal gas that is used for distributing is installed in the bottom of furnace chamber.The cooling gas entry is located at the bottom of body of heater.Cooled coal gas that enters from the stove bottom and the hot semicoke counter current contact that moves down carry out heat exchange, reach the effect of cooling semicoke.The semicoke that is cooled enters Jiao's dish of furnace bottom, fills the effect that water plays water seal and quenching in the burnt dish.By actuator drives Jiao dish and grate rotation, make burnt dish in continuous rotary course, by the black groove of Jiao semicoke is discharged out of the furnace continuously.Coal gas is discharged from gas exit.
The utility model is owing to adopted the steel cylinder, and so inner lining refractory block is simple in structure.The transmission mechanism that the double belljar at top adds coal bin and bottom makes the rotation continuously of burnt dish, has realized the whole process that continuous coal discharges of the coke continuously.Several gas jets that radially are provided with by stove in addition with self-produced coal gas material supply thermal source in stove continuously, do not need external thermal source heating, have reduced fuel consumption and production cost.Remaining coal gas also can be failed outward, is used for industry and civilian.The air gas variable valve that is provided with before the gas jet.Can adjust the ratio of coal gas and air at any time, easy to operate, flexibly.
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is a structural representation of the present utility model.
Describe details and working condition in detail below in conjunction with Fig. 1 according to the concrete charring furnace that the utility model proposes.
This charring furnace, diameter are 1.5 meters, and body of heater adopts steel cylinder 3, inner lining refractory block 4.The coal bin 1 of adding of furnace roof portion adopts the double belljar structure, is made up of two coal bins up and down, and during coal, the chain operation of two valve switching motions is to realize the continuous operation of production.Fix a skirtboard 2 on furnace chamber top.Hand-hole 5 at the body of heater middle part is used for shutdown maintenance.Four fire exploring holes 6 are arranged on the body of heater middle and lower part, along the housing radial distribution, in the bottom of fire exploring hole along uniform six gas jets 7 in housing footpath, the ingress of this gas jet, be provided with coal gas and air control valve,, regulate the ratio of coal gas and air at any time according to inner operating.In the bottom of furnace chamber grate 8 is housed, cooling coal gas enters stove internal cooling layer from body of heater bottom cooled coal gas inlet 11 through grate.Be filled with water in the burnt dish 9, play the effect of water seal and quenching.By transmission mechanism 13, drive burnt dish and fire grate rotation, make burnt dish in rotary course continuously, by the black groove of Jiao 10 semicoke is discharged out of the furnace continuously, coal gas is from gas exit 12 discharges.
During work, coal charge adds coal bin 1 through double belljar, enter in the stove from furnace roof portion, pass through the drying layer (105～120 ℃ of temperature) of coal from top to bottom successively, the variable valve of the air that coal gas that destructive distillation layer (temperature 700-800 ℃) and gasburner 7 spray into and nozzle clamp cover into by being provided with before the nozzle, in the nozzle exit burning, produce high-temperature gas, reach destructive distillation with the coal counter current contact that moves down.Pyrogenous semicoke enters the cooled coal gas counter current contact that cooling layer (250～350 ℃ of temperature) and furnace bottom blast by the destructive distillation layer, carry out heat exchange, after being cooled to 250～350 ℃, semicoke enters burnt dish, after water in the burnt dish of quilt cools off once more, by burnt dish of actuator drives and grate rotation, make burnt dish in rotary course continuously, semicoke is discharged out of the furnace continuously by the black groove of Jiao 10.The coal gas that reaction back produces is discharged from gas exit 12, and a part enters gas jet by coal gas and the air control valve that is provided with before the gas jet, supplied heat source in stove continuously, remainder can fail outward be used for industrial and civilian.
