Abstract
A unique cleaning method and structure is disclosed which pulses pressurized fluid into a vessel. The pulses clean internal surfaces within the vessel. The internal surfaces may include the internal surfaces of the vessel, or may include items to be cleaned which are placed within the vessel. The pulsed fluid preferably cavitates within the vessel, and impacts upon the surfaces to be cleaned, removing impurities such as scale or other buildup. The fluid may then be directed downstream and recirculated back through the system. Pulses of fluid are cyclically controlled by a control valve to optimize the amount of cavitation within the vessel.
Claims19
A method of cleaning internal surfaces within a vessel comprising the steps of:
- (1) cyclically directing pulses of a pressurized fluid into the vessel, such that the pulses impact upon internal surfaces to be cleaned the pulsing of the fluid being created by cyclically operating a valve, and disposing a wave sensor on a fluid line between the valve and the vessel, the wave sensor delivering a feedback signal to a controller for the valve, and controlling the valve in response to the feedback to maintain a desired frequency;
- and
- (2) directing the fluid out of the vessel.
