Problems solved by technology

However, the application of reed whistle in sewage treatment is very limited, mainly as follows: (1) It is difficult to increase the amplitude of sound pressure greatly, which makes it difficult to further increase the cavitation intensity; (2) It is difficult for the reed whistle to accurately find the node to set (3) It is difficult to excite reed vibration in viscous media and suspension liquid containing hard particles, which brings difficulties to the wide engineering application of reed whistle

Abstract

The invention relates to a turbulence resonance fluid sounder. According to the turbulence resonance fluid sounder, a liquid medium is disturbed through interaction of a jet flow of a convergence type nozzle and an obstacle body with grooves, the counteractive is produced to a jet flow near the nozzle, therefore, an alternating pressure field and an alternating speed field are produced between the nozzle and the obstacle body, natural vibration of a resonance rod is simulated, sound waves are then emitted, key technical defects existing in a traditional resonant wedge whistle can be effectively overcome, and the turbulence resonance fluid sounder replaces the traditional resonant wedge whistle to be widely applied to waste water processing. The turbulence resonance fluid sounder is simple in structural design, low in cost, large in sound pressure amplitude, and capable of effectively improving pressure field intensity of a pulse area and cavitation intensity of the pulse area. Meanwhile, vibration energy of the resonant rod enables the sound waves to be spread farther, and therefore the range of a cavitation area is increased. When the turbulence resonance fluid sounder is applied to waste water processing, the ultrasonic wave waste water processing effect can be effectively improved and enhanced, and the turbulence resonance fluid sounder is suitable for industrialized application.

Description

Technical field [0001] The invention relates to the technical field of fluid sound research, in particular to a turbulent resonance fluid sound generator. Background technique [0002] In the past two decades, water pollution in our country has been very serious. The main sources of water pollution are industrial wastewater, agricultural wastewater and urban domestic sewage. Especially the hard-to-degrade "three-caused" (carcinogenic, teratogenic, genetic mutation) organic pollutants, which not only consume a large amount of dissolved oxygen in the water body, make the water body lose the ability to purify itself, but also can exist in the environment for a long time. It invades into the human body through the food chain and gradually accumulates, posing a serious threat to human health. At the same time, due to water pollution, many water resources cannot be reused, which aggravates the scarcity of water resources and affects the sustainable use of the environment and the susta...
