Abstract
The vacuum loading cleaning system includes a pair of interconnected pressure vessels containing a cleaning liquid which is pumped through a heat exchanger and into a dirty tank. Cleaning liquid and dislodged contaminants are sucked up from the dirty tank by a partial vacuum in the pressure vessel. Solids and cleaning liquid from the pressure vessel are separated by a solids separator with the cleaning liquid being passed through a centrifuge to remove fine solids before being returned to the pressure vessels. A skimmer in a pressure vessel removes floating solids and liquids. A phase separator is mounted beneath the suction inlets of a pressure vessel to speed the separation and concentration of solids, liquids and gases. 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.
