Description
Technical field
The utility model relates to a kind of destructive distillation device for preparing coal tar, shale oil.
Background technology
The selection of existing destructive distillation device has following requirement: the gas retort that oily yield is high, treatment capacity is large, adaptability to raw materials is wide and water power steam comprehensive energy consumption is low, the oil yield is high refer generally to will be higher than raw material aluminium rice steamer oil-containing 85% better, treatment capacity refers to that industrialized single stove treatment capacity should be greater than 1000t/d, adaptability requires easy handling, control, the variation of the performance such as granularity, oil length, water ratio, the heat that can adapt to raw material collapses, calorific value and treatment capacity.
Existing retorting technique can't satisfy whole requirements, just under the prerequisite that guarantees economy, as much as possiblely satisfies above-mentioned condition.
Existing coal and oil shale retort device can be divided into externally heated retort oven and internally heated retort oven:
Externally heated retort oven is because heat transfer rate is low, and treatment capacity is little, is difficult for amplifying, and is existing superseded, seldom is used.And internally heated retort oven can be divided into bulk, small-particle and powder destructive distillation by raw material granularity, is divided into gas, solid destructive distillation by the difference of thermal barrier.The multiplex gaseous heat-carrier of general block raw material, the multiplex solid thermal carriers of small-particle and powder stock.
The vertical stove of the internal heat type of gaseous heat-carrier is used wider the have strange three sections stoves in Shandong, Gas stove, Brazilian Pei Teluosekesi stove, Fushun stove and full circulation carbonization furnace etc., and raw material is descending in stove, and the hot gas adverse current is by material in gas retort.The gas retort structure mainly is divided into drying and preheating section, retort section and semicoke cooling section.Epimere destructive distillation oil gas, retort section destructive distillation at 500～800 ℃ of temperature, the semicoke cooling section air cooling that is cooled in bottom but effluxes afterwards.
