Problems solved by technology

However, the above-mentioned test coke oven still has not overcome the problem of low actual tar yield, because in the above-mentioned test coke oven structure, there are not enough pyrolysis gas flow channels, and the pyrolysis gas can only be discharged from the furnace roof, which is easy to cause heat The decomposed gas stays in the coaling box for a long time, and the gaseous tar in it undergoes secondary cracking due to continuous exposure to high temperature, resulting in the actual tar yield being much lower than the theoretical value, which cannot reflect the real tar yield

Abstract

A pyrolysis device for carbonaceous materials comprises a carbonization chamber, a carbonaceous material container, a programmed temperature controller, a heating chamber and a sealing cover. The carbonization chamber comprises at least one pyrolysis gas outlet; the carbonaceous material container is placed in the carbonization chamber, and at least one pyrolysis gas ventilating port is arranged on at least one side wall of the carbonaceous material container; and the heating chamber is positioned around the bottom or the lower side of the carbonization chamber. The pyrolysis gas outlets are positioned around tops of the side walls of the carbonization chamber, sandwich gaps are formed among outer surfaces of the side walls and / or the outer surface of the top of the carbonaceous material container and inner surfaces of side walls and / or the inner surface of the top of the carbonization chamber, and are used as pyrolysis gas flowing channels, the pyrolysis gas ventilating ports are communicated with the pyrolysis gas outlets via the pyrolysis gas flowing channels, and gaseous pyrolysis products are quickly exhausted out of the carbonization chamber via the pyrolysis gas ventilating ports, the pyrolysis gas flowing channels and the pyrolysis gas outlets. The pyrolysis device prevents secondary pyrolysis of condensable pyrolysis products, and accordingly the yield of liquid pyrolysis products is greatly increased.

Description

technical field [0001] The invention relates to a carbonaceous material pyrolysis or dry distillation device and system, in particular to a medium-low temperature pyrolysis or dry distillation device and system for small or experimental carbonaceous materials. Background technique [0002] The medium and low temperature pyrolysis of carbonaceous materials and the dry distillation technology for separating and extracting high value-added oil and gas components, as a carbonaceous material conversion and utilization technology that meets the requirements of clean energy, play an important role in the rational utilization of coal and other carbonaceous material resources in my country. meaning. [0003] Pyrolysis or dry distillation devices are crucial to the conversion and utilization of carbonaceous materials mentioned above. At the same time, carbonaceous materials with different properties or types require pyrolysis or dry distillation devices with different structures. Peopl...
