VERFAHREN ZUR VERGASUNG VON ABFALLFLUESSIGKEITEN, DIE ORGANISCHE BESTANDTEILE ENTHALTEN UND SCHACHTOFEN ZUR DURCHFUEHRUNG DES VERFAHRENS

摘要

A waste liquid is dripped down into a shaft chamber 1 of a shaft furnace 2 at the bottom of which chamber is a rotating conical grate 3 on which is an incandescent bed of carbon-rich material 6 than can be supplied from the top of the shaft. Oxygen is supplied through holes 17 of a raised head 15 of the grate. The liquid, vaporized as it reaches the incandescent bed, is drawn through the bed 6 where it is gasified and where high molecular weight components are cracked, forming a gas mixture that is drawn off through the duct 18 at the bottom of the shaft while solid residues of the liquid collect in the bed 6 from which ashes pass through a peripheral gap 5 and drop down through the duct 18 to a collecting hopper 21. The gas mixture then flows upward through a second incandescent bed 24 of carbon-rich material, such as coke or wood charcoal, where the oxygen, exhausted along with the gas mixture from the shaft 1, maintains a temperature between 900 DEG and 1000 DEG C. There the remaining high molecular weight contents of the gas mixture are cracked, while entrained ash particles are held back by the bed of coals. A suction blower 20 pulls out a gaseous product useful as fuel.
