Abstract

The invention provides a high-pressure hydrodynamic cavitation stirrer. The high-pressure hydrodynamic cavitation stirrer comprises a shell, a cavitation rotating wheel, an inducer, a centrifugal impeller and a driving device, wherein a double-layer channel is arranged in the shell, the outer-layer channel is an outlet, and the inner-layer channel is an inlet; a centrifugal impeller is installed in the shell and used for pressurizing and inputting the inner-layer channel into the outer-layer channel, and the centrifugal impeller is connected with a driving device; an inducer is installed in the inner-layer channel, a cavitation rotating wheel is installed in the outer-layer channel, the centrifugal impeller, the inducer and the cavitation rotating wheel rotate coaxially, and the centrifugal impeller drives the inducer and the cavitation rotating wheel to rotate synchronously; a cavitation hole is formed between the outer layer channel and the inner layer channel and located between the cavitation rotating wheel and the inducer. A high-flow-speed and high-pressure area is provided for the device through the inducer and the centrifugal impeller, cavitation is generated in the high-flow-speed and high-pressure area through the cavitation runner, and organic pollutants in sewage can be efficiently treated and degraded.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a high-pressure hydraulic cavitation mixer. 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. [0003] 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 an...
