Description
Technical field
The present invention relates to the pyrolysis plant field of solid fossil fuel, particularly relate to a kind of outer hot vertical tilting pyrolysis oven of pyrolysis solid fossil fuel.
Background technology
At present; with the method production cleaning of pyrolysis or the fuel of upgrading; both can reduce the environmental pollution that direct burning solid fossil oil causes; can make full use of the compound of high economic worth contained in solid fossil fuel again, there is protection of the environment, energy-conservation and rationally utilize the broad sense of solid fossil resource.
And according to the difference of pyrolytic process, the pyrolysis oven adopting has internal thermal upright stove and external-heat upright furnace, external-heat upright furnace technique be wherein nineteen fifties in the method for Britain, German widely used production city coal gas and semicoke, main technique has hot vertical heater etc. outside Wood (W-D) charring furnace, Kao Baisi (Koppers) Lu He China Inner Mongol Yi Dong group.The groundwork principle of external-heat upright furnace is: the upright thin-and-long structure of laying fireproof bricks for destructive distillation chamber, coal enters into indoor straight-through decline the continuously of heated destructive distillation from top coal bunker through suitably constructing, coal is heated and pyrolysis gradually by showing tremendous enthusiasm road in folding process, the speed that coal moves down starts by pyrolysis and reaches destructive distillation chamber bottom to become the coke time and control with coal, and the byproducts such as raw gas that in pyrolytic process, coal discharges gradually rise to top, destructive distillation chamber and are exported.
At least there is following shortcoming in existing external-heat upright furnace: because destructive distillation chamber is upright thin-and-long structure, heated solid materials is indoor straight-through decline the continuously of destructive distillation, if solid material granularity is less than 10mm, there is the closely knit filling destructive distillation of the solid materials interior space, the easy adhesion of material in pyrolytic process, and do not have or rare space, and then cause byproducts such as pyrolysis gas that in pyrolytic process, fossil oil discharges to be gradually difficult for rising to top, destructive distillation chamber being exported, therefore the small particle size solid fossil fuel that existing external-heat upright furnace can not be less than 10mm to granularity is carried out effective pyrolysis.
