Hydraulic cavitation generator for combined treatment of organic pollutants

Abstract

The invention relates to a hydraulic cavitation generator for combined treatment of organic pollutants. The hydraulic cavitation generator comprises a water inlet pipe and a cavitation pipe communicated with the water inlet pipe; the outlet of the water inlet pipe is convergent, and a combined cavitation head is arranged at the connection of the water inlet pipe and the cavitation pipe; the combined cavitation head is formed by splicing a perforated plate and a nozzle and the center line of the nozzle is coincided with the central axis of the inlet pipe; a reed is arranged in a cavity of the cavitation pipe, and a wedge film of the reed is opposite to the nozzle outlet. The perforated plate is combined with the reed whistle, and the reed is placed in the focus position of the cavitation cavity. When water from the nozzle outlet impacts the reed, the vibration produces sound waves. Sound waves are emitted from the focal position of the cavitation cavity and the sound waves are reflected by the cavitation hook surface of the conical variable section and will be emitted parallel to the direction of the flow, so the radiant range of a loud noise is expanded, cavitation bubbles in the wider area can be effectively cavitated under the effect of sound energy, and the collapse degree of the cavitation bubbles will be further enhanced, so as to improve the degradation ability of organic pollutants.

Description

technical field [0001] The invention belongs to the technical field of sewage cavitation treatment equipment research, in particular to a hydraulic cavitation generator for combined treatment of organic pollutants. Background technique [0002] Water is the material basis for human survival and development, and the protection and recycling of water resources is one of the most important issues in environmental protection. China is one of the thirteen water-poor countries in the world. In the past two decades, my country's water bodies have been seriously polluted. The water bodies surveyed in 118 large and medium-sized cities show that 40% of them are heavily polluted. The main sources of water pollution are industrial polluted wastewater, agricultural polluted wastewater and urban domestic sewage. Especially the "three causes" (carcinogenic, teratogenic, and mutagenic) organic pollutants that are difficult to degrade, they not only consume a large amount of dissolved oxyge...
