The invention relates to a rapid powdered coal pyrolysis and semi-coking combined device and a process method thereof, belongs to the technical field of powdered coal pyrolysis and provides a rapid powdered coal pyrolysis and semi-coking combined device synchronously executing powdered coal pyrolysis and semi-coking gasification and high in heat efficiency, low device investment and safe and stable in operation and a process method thereof. According to the adopted technical scheme, a bottom discharging port of a powdered coal buffer bin is connected with a rapid powdered coal pyrolysis reactor, the rapid powdered coal pyrolysis reactor is communicated with a semi-coking gasification reactor, and pyrolysis coal gas produced by the rapid powdered coal pyrolysis reactor is subjected to separation and dust removal through a multi-stage separator; the separated dust is fed into a dust tank; the separated semi-coking dust is fed into a semi-coking buffer bin, the semi-coking buffer bin is connected with the semi-coking gasification reactor, a gasifying agent inlet pipe is arranged on a fire grate of the semi-coking gasification reactor, the bottom discharging port of the semi-coking gasification reactor is provided with a dust slag tank, and a slag outlet of the dust slag tank is connected with a slag cooling machine. The rapid powdered coal pyrolysis and semi-coking combined device is widely used for powdered coal pyrolysis.
Description
technical field [0001] The invention relates to a pulverized coal fast pyrolysis and semi-coke gasification combined device and a process method thereof, belonging to the technical field of pulverized coal pyrolysis. Background technique [0002] my country's energy structure is characterized by "rich coal, poor oil, and little gas", and coal will continue to be the main energy source in my country for a period of time to come. The economic development of the western region needs the support of the new coal chemical industry. [0003] During coal mining and subsequent processing, 40% of the pulverized coal with particle size less than 10mm will be produced, and this part of coal is currently mainly used as fuel. Since the very useful chemical components such as phenol and naphthalene and coal tar are not extracted from coal and burned directly as fuel, in fact this is a waste of energy. [0004] At present, severe smog and environmental protection requirements also require...
