Problems solved by technology

Although the Venturi tube of this structure solves the connection problem between the various sections of the pipeline, its material requirements are special and the processing is difficult. Ordinary equipment cannot realize the processing of a large-length Venturi tube, which restricts its promotion and application.
In addition, the traditional Venturi tube is used for water treatment. Due to structural reasons, a single-stage structure is mostly used, but there are problems of small reaction area and low efficiency.
Restricts its application in hydraulic cavitation technology

Abstract

The invention discloses a novel venturi tube type hydrodynamic cavitation water treatment device. A left bracket is arranged at the left end in a housing; a right bracket is arranged at the right end in the housing; a rectifying rod with a central line coincident with that of the housing is arranged on the left bracket and the right bracket; the rectifying rod is a rod-like body, of which two end surfaces are parallel planes vertical to the central line and the side surface is a cosine rotating curved surface, or circular truncated cone bodies integrally connected through a middle cylindrical body are arranged at the two ends of each of at least two cylindrical bodies; and end cylindrical bodies are arranged at the end parts of the circular truncated cone bodies on the outer sides of the cylindrical bodies at the two ends. Compared with the conventional venturi tube, the venturi tube has the advantages of simple structure, simplicity for processing, convenience for mounting, high pressure resistance, good sewage treatment effect and the like, and can be used for sewage purification treatment.

Description

technical field [0001] The invention belongs to the technical field of water treatment, and in particular relates to a novel Venturi tube type hydraulic cavitation water treatment device. Background technique [0002] The extreme physical conditions formed by the turbulence effect, perturbation effect, interface effect and energy accumulation effect caused by ultrasonic cavitation provide a very effective way to strengthen and accelerate chemical reactions. In recent years, environmental problems have become increasingly prominent, and the application of power ultrasound in water treatment has been extensively and deeply studied. However, ultrasonic cavitation only produces energy concentration in a small range near the sound source, and the cavitation effect is strong, so it has a good effect on the object to be treated. At the same time, only 5% to 10% of the total energy consumption of the ultrasonic transducer is used for cavitation, and the remaining 90% to 95% of the ...
