An angular multi-stage cavitation generator

Abstract

The invention provides an angle-shaped multi-stage cavitation generator, which includes a casing, a first-stage cavitation sleeve, a second-stage cavitation sleeve, a third-stage cavitation sleeve, a sealing ring and a bottom cover. The first-stage cavitation sleeve, the second-stage cavitation sleeve and the third-stage cavitation sleeve are sequentially installed inside the casing from the outside. A number of first-level cavitation holes are evenly distributed on the wall of the first-level cavitation sleeve, a number of second-level cavitation holes are evenly distributed on the wall of the second-level cavitation sleeve, and a number of second-level cavitation holes are evenly distributed on the wall of the third-level cavitation sleeve. A number of three-stage cavitation holes are arranged, through which the inlet and outlet of the casing are connected. The cavitation occurrence hole includes a front section, a diffuser section and a column, and the diffuser section is a tapered hole; the direction of the cone angle of the tapered hole gradually expands along the direction of liquid flow; the cone angle of the tapered hole is 45 ~ 75 degrees. The invention has a simple and compact structure, and the multi-stage cavitation sleeve structure can efficiently treat and degrade organic pollutants in sewage, and has broad development space and application prospects.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to an angular multi-stage cavitation generator. Background technique [0002] With the continuous development of modern industries such as pharmaceuticals, chemicals, printing and dyeing, the artificially synthesized macromolecular organic matter and refractory chemical substances in water bodies are increasing year by year, making it difficult for traditional sewage treatment methods to adapt to the current increasingly stringent environmental protection requirements. The advantages of cavitation to degrade organic pollutants are reflected. Hydrodynamic cavitation is a hydrodynamic phenomenon. The local high temperature and high pressure, luminescence, discharge, strong shock wave, high-speed jet and other extreme conditions provided by the cavitation bubbles in the liquid during the movement and collapse of the hydrodynamic cavitation process can strengthen the physical and chemic...

Problems solved by technology

[0003] Existing cavitation generators mostly adopt a single-stage structure, which is prone to incomplete cavitation reactions, resulting in residual organic pollutants in the treated sewage, requiring further hydraulic cavitation degradation to achieve the ultimate goal of sewage treatment
