Abstract
A rotary apparatus and method is provided for cleaning liquid storage tanks, particularly above ground tanks. The rotary cleaning apparatus includes a Tee housing that is rotated around a vertical axis and a nozzle housing mounted to the Tee housing for rotation around a horizontal axis, resulting in a 360° spherical spray pattern. A set of downspray nozzles is mounted to the Tee housing at an angle to the vertical axis to rotate with the housing and generate a conical spray pattern. In the preferred embodiment, the apparatus draws liquid stored in the tank through a filter and pumps the filtered liquid through the rotary cleaning apparatus.
