Integrated pyrolysis and gasification device for seed coal and integrated pyrolysis and gasification method for seed coal

The invention provides an integrated pyrolysis and gasification device for seed coal and an integrated pyrolysis and gasification method for seed coal. The integrated pyrolysis and gasification devicecomprises a raw material bin and a reaction bin, wherein the raw material bin is used for storing and discharging seed coal; the reaction bin is used for pyrolyzing and gasifying the seed coal in theraw material bin; an inner cavity of the reaction bin is divided into a pyrolysis area, a gasification area and a coke discharging area; the gasification area and the coke discharging area are arranged below the pyrolysis area in parallel; the seed coal in the raw material bin is pyrolyzed to generate semicoke in the pyrolysis area by utilizing high-temperature synthesis gas generated by gasification as a heat carrier; a part of the semicoke enters the coke discharging area and is discharged as a semicoke product; and the other part of the semicoke enters the gasification area and is gasified, and generated high-tempe
