METHOD AND APPARATUS FOR QUENCHING OF HEATED BULK MATERIALS

摘要

In the present method the bulk material, especially coke, is maintained at a substantially constant level on a substantially horizontal support surface. The quenching liquid is permitted to flow uniformly through the bulk material for about 45 to 90 seconds until the vapor temperature is cooled down to at least 400 DEG C. The quantity of the quenching liquid which is uniformly distributed over the bulk material is selected so that it evaporates substantially completely, except for a small moisture content in the quenched material. The present bulk material quenching apparatus has a fireproof container resting on a supporting box, the top of which is a grid structure which simultaneously forms a permeable bottom for the quenching container which is provided with a tightly closing cover. A pipe conduit is connected to the cover which has a plurality of conduit outlet openings directed into the container. The box on which the container rests has at least one hinged side wall.
