ABSTRACT:
The cleaning system includes a pressure vessel containing a cleaning liquid pumped out of the pressure vessel and into a dirty tank. Cleaning liquid and dislodged contaminants are sucked up from the dirty tank by a partial vacuum created above the cleaning liquid within the pressure vessel. Solids and cleaning liquid are pumped from the pressure vessel at a first rate and are separated by a solids separator with the cleaning liquid being centrifuged to remove fine solids and then collected in a makeup tank. Cleaning liquid from the makeup tank is pumped into the dirty tank at a second rate, less than the first rate. Excess liquid in the makeup tank is sucked back into the pressure vessel. A phase separator, mounted beneath the suction inlet, speeds the separation and concentration of solids, liquids and gases/vapors. The phase separator includes a number of vertically aligned, downwardly and inwardly tapered truncated conical concentrators with open tops and open bottoms above and below the free surface.
