Abstract
A carbonaceous substance dry powder gasification device and method, the device comprising from bottom to top a lower cooling and purification section (1), a gasification reaction section (2), a cooling reaction section (3) and an upper cooling and purification section (4); an initial cooling device is disposed at the connection between the cooling reaction section and the gasification reaction section; and a plurality of nozzles are circumferentially arranged in the gasification reaction section. The method comprises: a gasification reaction is conducted between a carbonaceous substance and an oxygenated gasifying agent to generate crude synthesis gas and ash; part of the crude synthesis gas and most of the ash go downstream for cooling and gasification, and the cooled and ash removed crude synthesis gas is transferred to subsequent processes, and the quenched ash is discharged through an ash outlet; the remaining crude synthesis gas and fly ash go upstream to mix with a cooling substance for cooling, and then are transferred to the cooling reaction section for reacting with the incompletely reacted carbon and added gasification agent; the crude synthesis gas and the fly ash are co…
