Problems solved by technology

However, the current research on hydrodynamic ultrasound requires a high fluid power source, the energy conversion rate is low, and only the gas-liquid two-phase mixing is considered, and the solid-phase interaction is ignored, resulting in a huge amount of gas required and high engineering costs.

Abstract

The invention discloses a reed type hydrodynamic ultrasonic gas-liquid-solid multi-phase mixer. The reed type hydrodynamic ultrasonic gas-liquid-solid multi-phase mixer comprises an upper cover, a lower bottom and a plurality of reeds. The upper cover and the lower bottom are detachably combined in a sealed mode to form a cavity. The multiple reeds are horizontally and fixedly arranged on the inner wall of the upper cover at intervals. The upper cover comprises a gas introduction pipe, a solid supporting frame and first nozzle passages. The lower bottom comprises a liquid introduction pipe and second nozzle passages. The tip end of any reed is opposite to the liquid outlet end of one of the second nozzle passages at the distance of 2-8 mm. Each second nozzle passage is of a narrow-seam structure 1-3 mm wide. The diameter of each first nozzle passage is 2-4 mm, and the first nozzle passages all enable gas to be sprayed towards one reed. Through introduction of the surrounding type reed structure and solid-phase materials, the atomization effect of the mixer is improved, the gas amount needed in the atomization process is lowered, and the reed type hydrodynamic ultrasonic gas-liquid-solid multi-phase mixer has the beneficial effects of being simple in structure, high in maneuverability, safe and reliable.

Description

technical field [0001] The invention relates to a gas-liquid-solid multiphase mixer. More specifically, the present invention relates to a reed type hydrodynamic ultrasonic gas-liquid-solid multiphase mixer. Background technique [0002] Atomization mixing devices are widely used in aerospace, aviation, metallurgy, spraying, oil exploration and other fields, especially in water mist fire extinguishing, and the fineness and uniformity of atomized particles of fine water mist directly determine the fire extinguishing effect . [0003] At present, the research on ultrasonic mixer is mainly divided into electric ultrasonic and hydrodynamic ultrasonic according to ultrasonic. Among them, electric ultrasonic requires external electrical equipment, which is too expensive to be widely used in industry; fluid dynamic ultrasonic uses fluid as power to excite the reed vibration of the ultrasonic mixer, so that the reed resonates with the fluid medium and emits ultrasonic waves.
