Problems solved by technology

However, the sound wave propagating in the liquid is easy to produce standing waves, and the existence of the standing wave sound field will form a blind area in the liquid. How to minimize or eliminate the standing waves to form a uniform and stable sound field distribution is the key to improving the processing efficiency

Abstract

The invention relates to a saw-toothed vortex field sound chaos cavitation apparatus, which belongs to the technical field of liquid flow chaos reactors. A reactor comprises a saw-toothed vortex fieldpipe, an outlet end of the saw-toothed vortex field pipe comprises an inner layer pipe and an outer layer pipe which are connected in a sleeving manner, along a water flow direction, and a pipe orifice of the inner layer pipe or / and the outer layer pipe is respectively processed in a saw-toothed structure, so that the discharged water form a vortex cavitation chaos field at the pipe orifice; andsound waves generated by an ultrasonic transducer can be scattered and refracted in various directions when propagating in liquid, and can form the uniform and stable sound field distribution in the liquid, so that the efficiency for degrading organic pollutants in a sound cavitation manner can be greatly improved.

Description

technical field [0001] The invention belongs to the technical field of liquid flow chaotic reactors, and in particular relates to a sawtooth vortex field acoustic chaotic cavitation device for treating organic pollutant wastewater by utilizing hydraulic vortex field and sound field chaos degradation. [0002] technical background [0003] According to the survey of the United Nations, my country is one of the thirteen water-poor countries in the world. At present, the total annual water consumption in the country is nearly 620 billion cubic meters, and the water shortage in normal years is more than 50 billion cubic meters. With the economic and social development and the impact of global climate change intensifying , the contradiction between supply and demand of water resources will become more acute. On the one hand, many water resources cannot be reused, which aggravates the scarcity of water resources. On the other hand, the sustainable use of the environment and the susta...
