First claim

What is claimed is:

1 . A hydrodynamic cavitation generating device, comprising:
a wheel disc provided with a plurality of flow passages, each flow passage having a throat orifice therein; a driving mechanism connected to the wheel disc and configured to drive a rotation of the wheel disc; and a water-inlet pipe that fits with a first side end face of the wheel disc, and is configured to inject water into a predetermined one of the flow passages when aligned with the predetermined one of the flow passages; wherein a first end of the water-inlet pipe is provided with a sealing ring and the water-inlet pipe is in sealed contact with the first side end face of the wheel disc through the sealing ring.

2 . The hydrodynamic cavitation generating device according to claim 1 , further comprising a water tank, wherein the wheel disc is set inside the water tank, a water-outlet of the water tank is connected to a water-inlet of a circulation pump through a pipeline, and a water-outlet of the circulation pump is connected to the water-inlet pipe through the pipeline.

3 . The hydrodynamic cavitation generating device according to claim 2 , wherein the wheel disc is rotatably connected to a bracket, and the bracket is fixed inside the water tank.

4 . The hydrodynamic cavitation generating device according to claim 1 , wherein the flow passages are evenly distributed along a circumference centered on a center of the wheel disc.

5 . The hydrodynamic cavitation generating device according to claim 1 , wherein an inner diameter of the water-inlet pipe is not less than a diameter of the flow passage.

6 . The hydrodynamic cavitation generating device according to claim 1 , wherein the driving mechanism comprises a driving member, and the driving member is connected to the wheel disc through a transmission mechanism, and is configured to drive the rotation of the wheel disc through the transmission mechanism.

7 . The hydrodynamic cavitation generating device according to claim 6 , wherein the transmission mechanism comprises a belt transmission mechanism or a gear transmission mechanism.

8 . A method for generating cavitation by using the hydrodynamic cavitation generating device of claim 1 , comprising:
submerging the wheel disc in water, driving the wheel disc to rotate by the driving mechanism, and introducing a water flow with a set pressure into the water-inlet pipe, wherein when the wheel disc rotates until the predetermined one of the flow passages is aligned with the water-inlet pipe, the water in the predetermined one of the flow passages is converted from static to flowing according to a set speed, generating cavitation bubbles.

9 . The method for generating cavitation by using the hydrodynamic cavitation generating device according to claim 8 , wherein lubricating oil is applied to an end face of the wheel disc in contact with the water-inlet pipe.
