Hydrodynamic cavitation sewage treatment equipment

Abstract

The invention discloses hydrodynamic cavitation sewage treatment equipment, which comprises a water pump, a main pipeline, a cavitator 1, a cavitator 2, an impinging stream chamber, a pressure gage 1, a pressure gage 2, a valve 1, a valve 2, a valve 3, a valve 4, a valve 5, a water tank 1, a water tank 2, a detection device, a drainage pipe, a return pipe, an overflow pipe, a branch pipeline 1, a branch pipeline 2, a support and a base. The two cavitators are concentrically and symmetrically arranged at two sides of the impinging stream chamber; sewage in the water tank 2 arrives the main pipeline through the water pump, respectively flows into the branch pipeline 1 and the branch pipeline 2, and then enters the cavitator 1 and the cavitator 2; the liquid subjected to cavitation treatment is sprayed out from the end parts of the cavitator 1 and the cavitator 2 so as to accomplish impinging in the impinging stream chamber. Each cavitator is formed by a Venturi tube, a perforated plate, a porous cavitation nozzle and an impinging nozzle. The hydrodynamic cavitation of the perforated plates, the internal cavitation of the Venturi tubes and the cavitation of the porous nozzles are organically combined, and the cavitation is intensified by additionally arranging the impinging nozzles, so that a cavitation effect with the highest level is achieved.
