Cavitation generating device and collision apparatus

Abstract

The application relates to the technical field of cavitation, and discloses a cavitation generating device and a collision equipment, which comprises an input pipeline and a first cavitation unit which are sequentially communicated, the first cavitation unit comprises a first cavitation shell with a first cavitation chamber and a flow guide groove which penetrates through the first cavitation shell and is communicated with the input pipeline and the first cavitation chamber at both ends, the flow area of the flow guide groove is smaller than the flow area of the input pipeline and the first cavitation chamber, the flow guide groove is configured to generate cavitation bubbles of fluid, and the first cavitation chamber is configured to make at least part of the cavitation bubbles collapse. Through the technical scheme, fluid enters the flow guide groove and generates cavitation bubbles, then the fluid enters the first cavitation chamber, and at least part of the cavitation bubbles collapse in the first cavitation chamber to generate cavitation. The cavitation generating device simplifies the structure of the cavitation generating device, and avoids the problem that the cavitation generating device is prone to be blocked.
