Abstract
Tank cleaning system is formed by an upper deck having a spout potion and a deck portion, injectors and a separation chamber having a conical bottom wall and a top formed by a waste baffle. The injectors connect the deck portion with the separation chamber so that the waste baffle and upper deck are axially separated to provide an outlet passage therebetween. The injector passages direct water through the upper deck and waste baffle into the lower chamber and impart a significant velocity component tangential to the chamber to the water flowing therethrough to impart a helical flow to the water in the chamber. A debris outlet passage is provided adjacent to the bottom of the lower portion of the chamber. The dirt laden stream enters the chamber through the injectors and dirt is separated by centrifugal action in the chamber and rejected through the debris outlet while the cleaned water passes through the outlet passage and is returned to the surrounding water.
