Abstract

The invention discloses a pneumatic ultrasonic multiphase mixer. The pneumatic ultrasonic multiphase mixer comprises a body, a gas flow guide chamber for introducing inflowing gas in the horizontal direction and for accelerating the gas to generate ultrasonic waves through resonance, a liquid flow guide chamber and a mixing chamber. The gas flow guide chamber comprises a flow guide chamber body, a center rod and a resonant chamber. The liquid flow guide chamber is arranged in the vertical direction of the main body and used for rupturing liquid through liquid nozzles, wherein solid powder is added to the liquid of the liquid flow guide chamber or the gas of the gas flow guide chamber in advance. The resonant chamber is contained in the mixing chamber. The mixing chamber is arranged in the horizontal direction of the main body and comprises an inner chamber body and a mixing chamber outlet communicating with the inner chamber body. Gas-phase continuous multiphase mist flow or liquid-phase continuous multiphase bubble flow is output through the mixing chamber outlet. According to the pneumatic ultrasonic multiphase mixer, mixing of the gas phase, the liquid phase and the solid phase is strengthened through the ultrasonic waves, and uniform multiphase mixed flow is formed; and water mist with the diameter being lower than 10 micrometers can be generated, the misting effect is better, the liquid-phase continuous multiphase bubble flow can be output as well, and thus the fire extinguishing efficiency is improved.

Description

technical field [0001] The invention relates to a gas-liquid-solid multiphase mixer. More specifically, the present invention relates to an aerodynamic ultrasonic multiphase mixer. Background technique [0002] Ultrasonic atomization has important applications in the field of liquid atomization. When the high-speed air flow is ejected from the gas nozzle, ultrasonic waves will be generated in the resonant cavity, and the ultrasonic waves will act on the centrifugal liquid film and high-speed jet, which will accelerate the breakage of the liquid film and jet flow, and the oscillation of the ultrasonic wave will make the gas-liquid mixing more uniform. In the past, the application of ultrasonic atomization was mainly in the open space of the nozzle, which required a high compactness of the structure, and the application was concentrated in the fields of combustion, metallurgy, and cleaning. [0003] The predecessors' application of Hartmann's whistle mainly focused on ultras...
