Carbonization furnace used for destructive distillation

Abstract

The invention discloses a carbonization furnace used for destructive distillation. The carbonization furnace comprises a base, a furnace body arranged on the base and a furnace pipe arranged in the furnace body in a hoisting way, wherein the upper end of the furnace pipe is hermetically connected with the upper end of the furnace body; a combustion heating device used for heating the furnace pipe is arranged below the furnace pipe; the base is provided with an air inlet used for providing the combustion heating device with air and an adjusting door used for controlling the opening degree of the air inlet; a heating gap is left between the furnace pipe and the furnace body; the furnace body is provided with a smoke exhaust port used for exhausting heating smoke; and the upper end of the furnace pipe is provided with a destructive distillation gas outlet used for discharging destructive distillation gas. The carbonization furnace used for destructive distillation employs a manner of direct heating of the furnace pipe; the heating of the furnace pipe is carried out in the furnace body; charging, cooling, discharging and other procedures are carried out out of the furnace body; and after heating of one furnace pipe is completed, another furnace pipe can be hoisted for heating, so destructive distillation efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of dry distillation, in particular to a carbonization furnace for dry distillation. Background technique [0002] Dry distillation is a reaction process in which solid organic matter is heated and decomposed in the absence of air. [0003] At present, dry distillation is mainly earth kiln dry distillation. In earth kiln dry distillation, heat is generated by internal combustion of raw materials. The heating process is controlled by the oxygen introduced, which requires high heat preservation. If the amount of oxygen introduced is large, the internal raw materials will be burned too much, and the product recovery rate will be reduced. Low, must be heated slowly, from loading raw materials, to heating, heat preservation, cooling, out of the furnace, the time of one furnace is about 10 days. Moreover, the smoke and dust produced by the earth kiln method cannot be well collected. Due to the long heat preservati...

AI Technical Summary

Problems solved by technology

In addition, the smoke and dust produced by the earth kiln method cannot be well collected. Due to the long heat preservation and heating time, the wood gas cannot be discharged in a concentrated manner, the wood gas cannot be well utilized, and the smoke and dust cannot be well processed and utilized.

Earth kiln loading must be done by people entering the kiln to load raw materials, which is labor-intensive
