Non-condensable gas purification system for RDF pyrolysis gas

The invention discloses a non-condensable gas purification system for RDF pyrolysis gas, and relates to the technical field of RDF pyrolysis. The non-condensable RDF pyrolysis gas discharged from secondary condensing and collecting equipment at the condenser temperature enters a buffer first for buffering, then a primary acid gas removal process is followed, and then through wet electric coke capture and secondary deep acid gas removal and purification, the non-condensable RDF pyrolysis gas is pressurized by a pressure pump and sent to a rear buffer gas tank for storage. A hot blast stove of apyrolysis furnace is sent for using according to the need, and the surplus part is used for direct combustion power generation or as fuel. With the increase of a non-condensable gas purification process, the investment and treatment cost of pyrolysis tail gas treatment equipment are greatly lowered, and the environmental protection effect of flue gas emission from the pyrolysis furnace is improved; moreover, the non-cond
