Apparatus for intimately contacting particulate solids with a heavy liquid

摘要

An apparatus for intimately contacting particulate solids with a heavy liquid, said apparatus comprising: (a) a contacting vessel; (b) a particulate solids inlet in communication with an upper end of the contacting vessel; (c) a generally conical deflector positioned in the contacting vessel beneath the particulate solids inlet; (d) an inlet control to control the flow of the particulate solids into the contacting vessel and prevent the discharge of gaseous materials from the contacting vessel; (e) a particulate solids outlet in communication with a lower end of the contacting vessel; (f) an outlet control to control the flow of particulate solids from the contacting vessel so that a bed of particulate solids is maintained in a lower portion of the contacting vessel; and, (g) spray nozzles positioned in the contacting vessel to spray heavy liquid onto the particulate solids as they fall downwardly to the bed of particulate solids. The spray nozzles are positioned so that no spray is directed toward the inner walls of the contacting vessel.
