Embodiment
As shown in Figure 1, pre-heated charring furnace, comprise body of heater shell 1, body of heater shell 1 is provided with smoke outlet 11, and the space that body of heater shell 1 surrounds is burner hearth, and burner hearth inside is provided with the carbonizing chamber 21 being surrounded by carbonized tube 2, the pay-off that is used to carbonized tube 2 convey materials is also installed on body of heater shell 1, preferably, pay-off is spiral feeder 3, and smoke outlet 11 places are provided with and are connected to spiral feeder 3 and are used to mud preheating that the flue 12 of fume afterheat is provided.
As shown in Fig. 2 and Fig. 3 are common, spiral feeder 3 inside are provided with the rotating shaft 31 being driven by power set, and be arranged on the screw-blade 32 in rotating shaft 31, rotating shaft 31 inside are provided with the post-receiving chamber 311 of hollow, screw-blade 32 inside are provided with the blade cavity 321 being communicated with post-receiving chamber 311, and flue 12 is communicated with post-receiving chamber 311.
Because material is through preheating tube 5 preheatings, carried out preliminary cracking, volume-diminished, so the internal diameter of preheating tube 5 is greater than the aperture of carbonized tube 2, be approximately the 1.1-1.5 of carbonized tube 2 internal diameters doubly.
Opening for feed 33 places of spiral feeder 3 are provided with rotary seal valve 331, and the carbon granules of carbonized tube 2 outlet 22 is provided with rotary seal valve 221, the arranging of rotary seal valve reduced contacting of material and oxygen, avoided the generation of Dioxins and oxynitride, pollution-free to realize carbonization process.
Preferably, body of heater shell 1 inwall is provided with silicate lagging material, to reduce the calorific loss in burner hearth.
The utility model is when carrying out carbonizing treatment, through twice preheating, preheating is for the first time when charging, owing to being connected with flue 12 between spiral feeder 3 and smoke outlet 11, the flue gas that the interior gaseous combustion in combustion chamber 41 produces is discharged by the smoke outlet 11 on burner hearth, part of smoke is disposed in atmosphere, a part enters spiral feeder 3 by flue 12, in spiral feeder 3, the structure that rotating shaft 31 and screw-blade 32 are hollow, flue gas directly enters post-receiving chamber 311 and blade cavity 321, and the material of spiral feeder 3 inside is carried out to first preheating.
Material after the first preheating of spiral feeder 3 enters in preheating tube 5 through feed-pipe 34, because preheating tube 5 is arranged in burner hearth, first the flue gas that in combustion chamber 41, gaseous combustion produces is disposed in burner hearth, because the waste heat of gaseous combustion in flue gas is now higher, there is first cracking in the material in preheating tube 5, volume-diminished, and produced a small amount of splitting gas, so the process of material secondary preheating is also the process of first cracking.
After material secondary preheating in preheating tube 5, through tremie pipe 52, naturally fall in carbonized tube 2, the interior gaseous combustion of incendiary pencil 4 in carbonized tube 2 outsides produces enough heats carbonized tube 2 is heated, make material carry out carbonization, as the gas part of fuel a small amount of splitting gas that first cracking produces from preheating tube 5, major part is the splitting gas that in carbonized tube 2, material cracking produces, and the two is all connected in incendiary pencil 4 by splitting gas transfer lime 6, mixes and fully burning with combustion air.
In the present embodiment, the material that carbide furnace carries out carbonizing treatment comprises mud, rubbish or biomass material.
The by product that the utility model can rationally effectively utilize carbonizing treatment process to produce, the needed heat of carbide furnace carbonizing treatment is all supplied with by carbonization by product, having realized sewage sludge harmlessness and minimizing processes, realized the reasonable utilization of resource: most of energy that carbonizing treatment consumes adopts the splitting gas producing in carbonization process, reduce energy consumption, avoided splitting gas waste; During carbonizing treatment, splitting gas and combustion air mixed firing, the flue gas with amount of heat producing in combustion processes enters in burner hearth, utilize the waste heat of flue gas to the preheating tube heating in burner hearth, make material carry out preliminary cracking, take full advantage of the heat energy that splitting gas burning produces, shortened the time of material in carbonized tube, improve working efficiency, reduced energy consumption.
Because an end opening is sealed in incendiary pencil one end, blind end is for splitting gas and combustion air air inlet mixed firing, opening end is used for discharging flue gas to burner hearth, because preheating tube is arranged in burner hearth, in flue gas with heat preheating tube is carried out to preheating, make the material in preheating tube carry out preliminary cracking, produce a small amount of splitting gas, the common energy gas as burning of splitting gas producing in splitting gas in preheating tube and carbonized tube, make energy gas abundance in incendiary pencil, sufficient combustion is complete, guarantees the quality of material carbonizing treatment.
Because material carries out preheating and preliminary cracking in preheating tube, the volume of material that is entered carbonized tube by preheating tube will be dwindled, therefore the volume of carbonized tube is compared with the small volume of preheating tube, save the installing space of carbonized tube, dwindled the overall volume of carbide furnace, saved floor space, simultaneously, because carbonized tube caliber is less, heat utilization rate is high, is conducive to save carbonization time.
Enter the flue gas in burner hearth, after to preheating tube preheating, by smoke outlet, enter flue, utilize its waste heat to carry out preliminary preheating to the mud of pay-off, therefore warm of the present utility model comprises a preheating of pay-off and preheating tube secondary preheating, heat utilization efficiency is high, and the heat that burning produces to carbonization splitting gas makes full use of, and has avoided energy dissipation.
