ABSTRACT:
A tank cleaning system wherein a cleaning liquid is sprayed into a dirty tank and simultaneously sucked out of the tank. The cleaning liquid is stored in a pressure vessel and incompletely fills the vessel to leave a space above the liquid. A pump draws the liquid from the bottom of the vessel through a line to be sprayed into the tank to be cleaned. A vacuum is created within the space above the free surface of the liquid within the pressure vessel by a vacuum pump. While spraying the cleaning fluid into the tank, a vacuum line sucks up the cleaning liquid and dislodged contaminants from the bottom of the tank. The vacuum line terminates at the pressure vessel so that cleaning liquid and contaminants are discharged into the vessel so that cleaning liquid and contaminants never pass through the vacuum pump. Solids settling on the bottom of the vessel are pumped out into a solids separator. Liquid collected by the solid separator is sucked back into the vessel by the vacuum in the vessel.
