Description
One, technical field
The utility model belongs to the technology remodeling of long-flame coal distillation apparatus, is specifically related to a kind of internal heat type smalls low-temperature pyrolysis rotary oven.
Two, background technology
At present, long-flame coal is produced blue charcoal and is generally applied internal heat type vertical retort, its ingredient requirement must be the lump coal of 30-80mm, and the lump coal of Modern coal mines mechanical mining only has 30% left and right, lump coal supply day is becoming tight and is on the high side, and the mixed slack coal that is less than in a large number 25mm does not have processed utilization, can only use as bunker coal.If these smalls at a low price can be extracted and become blue charcoal end after coal tar again and make carburelant, moulded coal, formed coke etc. by destructive distillation, its added value must improve very big like this, and has very high economic benefit.
Three, summary of the invention
The purpose of this utility model is the drawback that can not carry out to smalls destructive distillation in order to overcome existing vertical dry furnace, a kind of internal heat type smalls low-temperature pyrolysis rotary oven is provided, the main technical schemes of its solution, to build and have refractory brick (9) on body of heater (8) inner-wall surface of cylinder steel body structure, the formula end socket (4) of being association of activity and inertia is being welded at body of heater two ends, the transmitting gear (6) of the outer wall middle part welding of body of heater cogs and engages with drive unit (7), drive unit (7) is bolted on the pedestal (15) that drives guide rail, body of heater outside weldings three steel guide rails (5), this guide rail is separately fixed at supporting base (14) and drives on pedestal (15), the be association of activity and inertia central position of formula end socket of body of heater left end is fixed wtih spiral and enters device for coal (2), what spiral entered device for coal welds above coal charge case (1), coal gas discharger (3) is housed above the formula of being association of activity and inertia end socket, body of heater right-hand member is association of activity and inertia on the central position of formula end socket and is fixed wtih burner (10), below the formula of being association of activity and inertia end socket, connecting drawing mechanism (11), below drawing mechanism, be provided with refrigerating unit (12), refrigerating unit exit is connecting conveying belt (13).
Advantage of the present utility model: the one, rational in infrastructure, feed coal after in rotary oven, along continuous straight runs moves, conducts heat through combustion gas and refractory brick simultaneously, makes that coal is heated evenly, thermo-efficiency is high, the drawback that in having solved, hot vertical heater cannot destructive distillation smalls; The 2nd, refrigerating unit adopts the indirect type of cooling, the problem that does not exist water to pollute; The 3rd, smalls by deep processing and utilization after, can improve its added value, economic benefit is high.
Four, brief description of the drawings
Below in conjunction with accompanying drawing, the utility model embodiment is elaborated.
Fig. 1: be one-piece construction schematic diagram of the present utility model.
In figure, 1. coal charge case 2. spirals enter device for coal 3. coal gas dischargers 4. formula end socket 5. guide rail 6. transmitting gear 7. drive unit 8. body of heater 9. refractory brick 10. burner 11. drawing mechanism 12. refrigerating unit 13. conveying belt 14. supporting bases 15. of being association of activity and inertia and drive pedestal
Five, embodiment
A kind of internal heat type smalls low-temperature pyrolysis rotary oven as shown in Figure 1, make sometimes, first body of heater is mounted to right low left high position, angle of inclination is 1-3 degree, then the smalls of coal charge case (1) being entered to device for coal (2) through spiral sends in body of heater (8) thorax, the smalls entering after stove rotates and moves backward with rotary oven, burner sprays into burning gas in stove as thermal barrier and the heat exchange of coal counter current contact, coal is carried out to destructive distillation, within dry distillation of coal section temperature is controlled at 350-680 degree, refractory brick (9) accumulation of heat in burner hearth simultaneously, the effect of balance furnace temperature is played in heat release, make the heat in stove even, furnace temperature is stable.Coal moves backward through retort section again, automatically enters refrigerating unit (12) finally by drawing mechanism (11), is cooled to 80 DEG C to be below the blue charcoal of finished product and to be sent by conveying belt (13).The coal gas of dry distillation of coal byproduct in process is delivered to gas purification, recovery system by coal gas discharger (3), and the coal gas after purification is again through burner circulating combustion.
Claims (2)
1. an internal heat type smalls low-temperature pyrolysis rotary oven, it is characterized in that: be to build and have refractory brick (9) on body of heater (8) inner-wall surface of cylinder steel body structure, the formula end socket (4) of being association of activity and inertia is being welded at body of heater two ends, the transmitting gear (6) of the outer wall middle part welding of body of heater engages with the gear on drive unit (7), drive unit (7) is bolted on the pedestal (15) that drives guide rail, body of heater outside weldings three steel guide rails (5), this guide rail is separately fixed at supporting base (14) and drives on pedestal (15), the be association of activity and inertia central position of formula end socket of body of heater left end is fixed wtih spiral and enters device for coal (2), what spiral entered device for coal welds above coal charge case (1), coal gas discharger (3) is housed above the formula of being association of activity and inertia end socket.
