1. The utility model provides a strong shearing formula annular jet cavitation generator which characterized in that:

  • comprises a high-pressure water supply pipe (1), and an outflow pipe (5), a rectifier tube (2), a tubular contraction section (3) and a back pressure chamber (4) which are coaxially connected and communicated in sequence;

    the high-pressure water supply pipe (1) is vertically communicated with the rectifier tube (2);

    the outer diameter of the outflow pipe (5) is smaller than the inner diameter of the rectifying pipe (2);

    a tapered annular cavity is formed between the inner wall of the tubular contraction section (3) and the periphery of the outflow pipe (5) and is an annular nozzle (31), and the area ratio of the annular surface of the outlet of the annular nozzle (31) to the area of the section of the outlet of the tubular contraction section (3) is 0.25-0.50;

    one end of the back pressure chamber (4) is communicated with the tubular contraction section (3), the other end of the back pressure chamber is closed, and the back pressure chamber has an obstruction function and enables working fluid to flow back;

    the tubular constriction section (3) space between annular nozzle (31) export and back pressure chamber (4) is cavitation chamber (32), it is located between the biggest internal diameter of tubular constriction section (3) and the minimum internal diameter to go out flow tube (5) external diameter size, it is greater than back pressure chamber (4) internal diameter to go out flow tube (5) internal diameter, high-pressure feed pipe (1) is used for carrying high-pressure working fluid, and high-pressure working fluid passes through rectifying tube (2) with get into behind the cavity between flow tube (5) annular nozzle (31), annular nozzle (31) jet into working fluid blowout cavitation chamber (32), because the interference of back pressure chamber (4), working fluid takes place the backward flow, and the working fluid of backward flow flows through enter behind cavitation chamber (32) outflow tube (5), last working fluid pass through outflow tube (5) flow.
