Angular multi-stage cavitation generator

Abstract

The invention provides an angular multi-stage cavitation generator. The angular multi-stage cavitation generator comprises a casing, a first-stage cavitation sleeve, a second-stage cavitation sleeve,a third-stage cavitation sleeve, a sealing ring and a bottom cover, wherein the first-stage cavitation sleeve, the second-stage cavitation sleeve, the third-stage cavitation sleeve are sequentially installed inside the casing from the outside in, a plurality of first-stage cavitation generating holes, a plurality of second-stage cavitation generating holes and a plurality of third-stage cavitationgenerating holes are distributed on the wall surface of the first-stage cavitation sleeve, the wall surface of the second-stage cavitation sleeve and the wall surface of the third-stage cavitation sleeve uniformly and separately, and the inlet of the casing communicates with the outlet of the casing through the cavitation generating holes; each cavitation generating hole comprises a front section, a diffusion section and a column, each diffusion section is a conical hole, and the conical angle direction of each conical hole is gradually expanded in a liquid flowing direction; and the conicalangle of each conical hole is 45-75 degrees. The angular multi-stage cavitation generator has a simple and compact structure, and through the structure of the multi-stage cavitation sleeves, organic pollutants in sewage can be treated and degraded efficiently, and therefore the angular multi-stage cavitation generator has broad development space and a broad application prospect.

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...
