Vertical pyrolysis equipment for coal substance

摘要

Disclosed is a vertical pyrolysis equipment for coal substance, which includes an enclosed kiln body with an inlet and an outlet, a flame-gas heating pipelines provided inside the kiln body, coal substance conveying and pyrolysis passage formed between the flame-gas heating pipelines and inner wall of the kiln body, coal pyrolysis gas collecting tube connected with coal substance conveying and pyrolysis passage provided on the kiln. The heat generated by flame-gas heating pipelines is conducted and radiated to coal powder in the coal substance conveying and pyrolysis passage. The coal powder sufficiently absorbs the heat and is pyrolyzed into fuel gas, tar gas and coal with high heat value inside the coal substance conveying and pyrolysis passage. The pyrolyzed fuel gas and tar gas are transferred to the gas dedusting-liquifying mechanism outside the kiln through the connecting coal pyrolysis gas collecting tube for collecting, dedusting, separating and high-pressure liquefying.
