Design of Choking Cavitator and its Feasibility Study in Wastewater Treatment

Abstract:

A new cavitator-choking cavitator is designed on the basis of analyzing the choking cavitation phenomena that occurs in gas-liquid mixed flow of straight pipe ,in jet pump under operating limits and in steady adiabatic flashing flow of stepped circular tube as well as in a cylindrical pipe with a sharp edged-corner for the steady and unsteady flows. The feasibility preliminary research of choking cavitator is carried out with analysis the signals of cavitation noise and treating simulated wastewater (phenol solution). The results offers a new approach in cavitator development field at home and abroad because of the effect that treating simulated wastewater with choking cavitator is preferable,and the cavitation per energy produced by choking cavitator is higher than that by self-oscillated chamber nozzle.
