Abstract

The invention brings forward a coal pyrolysis apparatus and pulverized coal boiler combined system and a method for processing coal. The coal pyrolysis apparatus and pulverized coal boiler combined system comprises a rapid pyrolysis reactor, a pulverized coal boiler and a pyrolysis oil gas processing system. The rapid pyrolysis reactor comprises a multilayer regenerative type radiant tube, a semi-coke outlet and an air exhaust umbrella. The air exhaust umbrella comprises an umbrella portion and a handle part, which are communicated through gas. The pulverized coal boiler is communicated with the rapid pyrolysis reactor through the semi-coke outlet. The pyrolysis oil gas processing system is communicated with the rapid pyrolysis reactor through the handle part of the air exhaust umbrella. Through the coal pyrolysis apparatus and pulverized coal boiler combined system and the method for processing coal, complexity of the coal pyrolysis technology can be effectively reduced, and subsequent tar processing cost is decreased. Meanwhile, pyrolysis products are reasonably utilized, and generating cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of step-by-step utilization of coal, and in particular relates to a combined system of a coal pyrolysis device and a pulverized coal boiler and a method for processing coal. Background technique [0002] The semi-coke produced after coal pyrolysis can be used as fuel to generate electricity, while the existing coal pyrolysis topping process is mainly aimed at circulating fluidized bed power generation units. For example, the Process Institute of the Chinese Academy of Sciences and Zhejiang University use the hot ash produced by the circulating fluidized bed boiler as the heat carrier, and use the down-bed process to realize the pyrolysis of coal and recover the oil and gas. Because the existing system adopts a relatively complicated coal pyrolysis topping process of solid or gas heat carrier, and the oil and gas resources generated through the coal pyrolysis process, it is necessary to equip a corresponding ...
