A New Type of Rotating Liquid Whistle Cavitation Generator

Abstract

The invention discloses a novel rotating liquid whistle cavitation generator, which comprises a coaxially arranged rotor and a casing, the rotor is arranged in the casing through a rotating shaft, one end of the casing is provided with a feed liquid inlet, and the other end of the casing is provided with a There is a feed liquid outlet, and a heat exchange interlayer is arranged outside the shell; several rows of primary reeds are arranged at intervals along the axial direction on the outer wall of the rotor, each row of primary reeds is arranged at intervals on the radially outer side of the rotor, and several Rows of secondary reeds, each row of secondary reeds are arranged at intervals on the radial inner side of the housing, primary reeds and secondary reeds are arranged alternately in the housing, under the action of the rotor and the primary reeds, The material liquid of primary ultrasonic cavitation flowing around the rotor hits the secondary reed, and secondary ultrasonic cavitation occurs. Through the two-stage reed structure of the present invention, the improvement of cavitation efficiency and cavitation intensity is realized, and the uniform temperature control of the liquid inside the casing is realized by providing a heat exchange interlayer outside the casing.

Description

technical field [0001] The invention relates to the field of cavitation, in particular to a novel rotating liquid whistle cavitation generator, which can be applied to the fields of waste water treatment, liquid-liquid heterogeneous reaction, liquid-liquid mixing and the like. Background technique [0002] Liquid whistle has good application prospects in many engineering fields such as sewage treatment, cleaning dirt and liquid-liquid mixing. Commonly used liquid whistle devices mainly have a cantilever structure. The principle is to use high-speed and high-pressure water to impact the reed, causing the reed to vibrate, thereby causing ultrasonic cavitation. The conventional liquid whistle structure has disadvantages such as small processing capacity, complex structure, difficult maintenance, and high energy consumption, so the conventional liquid whistle has certain limitations.

[0005] Patent CN201120324072.3 discloses a wake vortex cavitation rotary generator. The device has a large liquid flux, but the device has a large liquid axial back-mixing, which affects the further improvement of cavitation efficiency

[0006] Patent CN201621439591.3 discloses a rotating liquid whistle cavitation generator. The device has a large liquid flux and can realize continuous operation. However, after the rotor drives the liquid to move at high speed, the kinetic energy of the liquid passes through the holes between the orifice plates and is converted into heat The form of the device is lost, the energy utilization rate of the device is low, and there is still room for improvement in the cavitation intensity and efficiency; and the device cannot achieve a constant temperature function, so it cannot effectively control the temperature of the liquid-liquid heterogeneous reaction
