Abstract

The invention discloses a rotary liquid whistle cavitation generator which comprises coaxially arranged rotors, housing and rotating shaft, wherein a sealing device is arranged between each end of the housing and the rotating shaft; a gap is formed between an inner wall surface of the housing and an outer wall surface of each rotor; a sealed inner cavity is surrounded by the inner wall surface of the housing, the outer wall surfaces of the rotors and the sealing devices; a liquid inlet is formed in one end of the housing; a liquid outlet is formed in the other end of the housing; the liquid inlet and the liquid outlet are communicated with the inner cavity; a plurality of annular partition plates are axially arranged in the housing at intervals; outer peripheries of the annular partition plates are fixed onto the inner wall surface of the housing; the rotor is rotationally penetrated in central through holes of the annular partition plates; the inner cavity is divided into a plurality of sealed sub-cavities by the annular partition plates; a short pipe is arranged on the partition plate between the adjacent sub-cavities; the two adjacent sub-cavities are communicated by the short pipe; a plurality of spring pieces are uniformly distributed on the rotor located in each sub-cavity; the spring pieces are fixed on the outer wall surfaces of the rotors in the radial direction of the rotors.

Description

technical field [0001] The invention relates to a rotating liquid whistle cavitation generator. Background technique [0002] Cavitation is the process of formation, development and collapse of vapor or gas voids (cavities) inside a liquid, and is a very complex fluid dynamics phenomenon. When the cavitation moves and collapses in the liquid, it will generate instantaneous high temperature and high pressure, accompanied by strong shock waves and high-speed jets. According to different methods of generating cavitation, cavitation can be divided into four categories: ultrasonic cavitation, hydraulic cavitation, optical cavitation and particle cavitation. [0003] The cavitation used in the chemical industry is mainly ultrasonic cavitation and hydraulic cavitation. Ultrasonic cavitation refers to a series of dynamic processes such as vibration, extrusion, shrinkage, fracture, growth and collapse of tiny bubbles (gas nuclei) in a liquid under the alternating action of positive...
