Combined hydraulic power cavitation device

Abstract

The invention relates to a combined hydraulic power cavitation device comprising a submerged body, a pore plate and a reed, wherein the submerged body is installed in a round pipeline to generate wake flow cavitation; the pore plate generates jet flow hydraulic power cavitation; the reed generates vibration cavitation; the submerged body is positioned on the upper stream in the round pipeline and is positioned at the center in the round pipeline; the submerged body is fixedly connected with the round pipeline by a submerged body fixing bracket; the pore plate and the round pipeline are fixedly connected and are installed between the submerged body and the reed; the porous plate is provided with a plurality of jet flow inlet holes; the reed is fixedly connected with the round pipeline by a feed fixing bracket and a reed fixing base; the reed fixing base is provided with an axial slit; the reed with a tip is embedded and fixed in the slit; and the tip of the reed just faces the center position of the jet flow inlet hole, and a gap is left. The combined hydraulic power cavitation device has the beneficial effect that a tail flow cavitation structure, a jet flow hydraulic power cavitation structure and a vibration cavitation structure are organically combined and unified to strengthen the cavitation effect. The combined hydraulic power cavitation device has the advantages of simple structure, good cavitation effect and strong practicability.

Description

technical field

[0001] The invention relates to the field of combined cavitators, in particular to a combined hydraulic cavitator. Background technique

[0002] At present, the cavitation used in the chemical industry is mainly divided into two types, one is the vibration cavitation caused by the vibration of the object surface in contact with the liquid, and the other is caused by the use of flow limiting devices such as orifice plates and Venturi tubes. Jet hydrodynamic cavitation. Usually these two types of technologies are researched and utilized in their respective branch fields. Vibration cavitation is to fix an object such as a reed on the downstream of the pipeline by flange or welding. When the liquid medium flows through the reed, it will cause the reed to generate ultrasonic vibration. The high amplitude and high frequency vibration of the reed can be in the liquid corresponding pressure waves are generated. Cavitation occurs when a pressure change occurs in a ...
