Description
Technical field
The present invention relates to the converter of a kind of external-heat low-temperature carbonization, mainly for the production of isolated air heating such as ature of coal, wooden, pitch, resins, to outlet temperature 300-600 ℃, make its pyrolysis obtain the device of carbonized material or pyrolysis product.
Background technology
Low-temperature carbonization is to produce one of important procedure in the gac process, and this process is heating raw materials, and non-carbon is reduced, and to produce the operation that is applicable to the needed carbonaceous material of activation procedure, is the master operation before activation.
The charring furnace of producing at present gac mainly contains internal heat type and external-heat, what most of enterprise still adopted is internal heat type charing converter, there are a lot of problems in this stove in actual production: as internal heat type charing converter high-temperature flue gas directly enters in stove, with material, directly contact, and mix with the volatile matter gas that the material pyrolysis produces, if missing of ignition in stove, in stove, volatile matter gas (tar and gas mixture) is easy to blast, if catch fire in stove, material will be ablated, and the charring process temperature is uncontrollable in claimed range, material strength and void distribution will be destroyed, and the material surface can should be excess Temperature and surperficial coking, greying, the activation procedure that is unfavorable for next step, due to the coal particle of material and cohere the ablated destruction of skeleton, and cause the product yield to descend.And this kind of internal heat type charring furnace is the monotubular structure, and it is too high that this structure can cause material to be piled up in stove, and the material sliding velocity is too fast, cause material impact power ambassador material broken too many before uncured, the product yield declines to a great extent.
Therefore, the internal heat type charring furnace is not suitable for the production high quality active carbon, and technical process is seriously polluted, the safety performance extreme difference, and the starting material loss is large, is not suitable with scale operation, can not adapt to gac fast development and customer demand.
The external-heat charring furnace does not contact material with high-temp waste gas, naked light and air, the volatile matter gas of material pyrolysis is not also together with high-temp waste gas and air mixed, so can not cause catching fire in blast and material channel, material is without ablation, and yield is high; Charing outlet temperature and temperature gradient distribution can be controlled, and material can be according to optimum technological temperature production, and the product strength of producing is high, and initial void distribution is good.The charring furnace of many material channels structure, can make the solid accumulation height reduce, and material rolling speed when rotating with body of heater reduced, and product breakage is reduced; The external-heat charring furnace of many material channels structure has increased the heating surface area of material, material is heated more even, and the thermo-efficiency of body of heater improves.
Therefore, the external-heat charring furnace becomes the trend and direction of development, domestic known public technology has: the Chinese invention patent specification sheets disclosed a kind of " the energy saving and environment friendly revolution charring furnace of external heat " (notification number: CN102092706B) on December 13rd, 2010, it has advantages of above-mentioned external-heat charring furnace, but because there is following critical defect in it, so can't drop into suitability for industrialized production:
1. because material channel adopts, link of boards is fixing forms an integral body, by an end, fix, the other end with the mode of freely-supported by structure, this kind of structure is only applicable to the shorter external-heat charring furnace of diameter smaller length; If charring furnace enlarged diameter length lengthens, this kind of structure can be because material channel be become whole rear weight excessive by link of boards, two pivot and longs are spent long and cause the stress in bending of material channel significantly to increase, reduced the permissible stress of material under the condition of high temperature due to material channel, when stress in bending is less than the permissible stress at the temperature of material channel material in processing requirement, will fracture, cause this patent to use in suitability for industrialized production.
2. only be provided with the material channel tightness system one at discharging tube sheet place, when normal production, the volatile matter gas that can't play in isolated discharging cover enters body of heater inside, cause equipment and process pipe to stop up, cause a large amount of contaminative tobacco (its composition is tar and coal gas) to discharge contaminate environment, and have the potential safety hazard of blast.
3. if material channel adopts non-circular closed cross-section, make material form local quick landing in the body of heater rotation process, so surging force is large, cause the material fragmentation of producing, affect quality product.
4. the material of not strengthening can be shed and caused fragmentation at the flight of low-temperature zone, and in high temperature section, flight is not set, can make the inhomogeneous of material pyrolysis, the serious quality that affects product.
5. when the inner heating of body of heater, can make skin temperature too high and produce distortion, cause equipment normally to use.
In sum, existing external-heat charring furnace all can not drop into suitability for industrialized production, even and when producing among a small circle, still there is unstable product quality in poor stability, production process, have environmental pollution, therefore, the gac suitability for industrialized production needs that a kind of reliability is high, the external-heat charring furnace of constant product quality, safety and environmental protection, but has no report in prior art.
