Abstract
The vacuum loading cleaning system includes a pair of interconnected pressure vessels containing a cleaning liquid pumped out of one or both of the pressure vessels, 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 above the cleaning liquid within the pressure vessel. A submersible booster pump aids passage of material along the vacuum line. Solids and cleaning liquid from the pressure vessel are separated by a solids separator with the cleaning liquid being returned to the pressure vessels. A skimmer is used within one or both of the pressure vessels to remove floating solids and liquid contaminants from the system. A phase separator, mounted beneath the suction inlets so that the material from the dirty tank passes through the phase separator, 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.
