Turbulence energy-reinforced hydraulic transient cavitated venturi tube

The invention provides a turbulence energy-reinforced hydraulic transient cavitated venturi tube, wherein a left support is arranged at the left side in a housing, a right support is arranged at the right side in the housing, the left end of a turbulence rod is arranged on the left support, the right end of the turbulence rod is arranged on the right support, a gap between the turbulence rod and the inner wall of the housing is a water flow passageway, at least two levels of venturi tubes which are connected with each other in series and surrounds the whole turbulence rod are arranged between the turbulence rod and the inner wall of the housing, and a throat part of the venturi tube is formed between the part of the turbulence rod with the maximum diameter and the inner wall of the housing. The turbulence energy-reinforced hydraulic transient cavitated venturi tube with the structure provided by the invention is simple in structure, convenient to install, and free from dead angle in the process of treatment, the transient cavitation in the process of hydraulic cavitation can be effectively reinforced, the turbulence energy-reinforced hydraulic transient cavitated venturi tube is high in sewage treatment efficiency, the technical problems of less cavitation strength, low phonochemistry reaction efficiency and the like in the conventional venturi tube hydraulic cavitation can be solved, and the turbulence energy-reinforced hydraulic transient cavitated venturi tube can be used for sewage treatment.
