Pulse diversion cavitation generator

Abstract

The invention relates to a pulse diversion cavitation generator. The pulse diversion cavitation generator comprises a pulse cavitation nozzle, an abrasion-resistant throat neck, an abrasion-resistant protecting sleeve and a flow stabilizing pipe. The abrasion-resistant throat neck is of a hollow cylindrical structure and internally provided with riflings. The abrasion-resistant protecting sleeve is arranged outside the abrasion-resistant throat neck in a sleeving mode and fixedly connected with the abrasion-resistant throat neck. The pulse cavitation nozzle is fixedly connected with one end of the abrasion-resistant protecting sleeve. The other end of the abrasion-resistant protecting sleeve is fixedly connected with the flow stabilizing pipe. The pulse cavitation nozzle, the abrasion-resistant throat neck and the flow stabilizing pipe are communicated in sequence. According to the pulse diversion cavitation generator, the pressure of cleaning jet flow is small and only is 10-16 MPa; the generator is not dangerous for a user, and the safety of personnel and dirt removing can be ensured; meanwhile, it is ensured that oil paint and an antifouling and anticorrosion coating on a processed surface cannot be damaged.

Description

technical field

[0001] The invention relates to a pulse diversion cavitation generator, which belongs to the field of cavitation jet cleaning devices. Background technique

[0002] Cavitation is a phenomenon of cavitation (vaporization or gasification cavity) that occurs suddenly in water or liquid flow at low pressure. The initial generation of cavitation is not only related to the vaporization pressure of the fluid, but also directly related to the size and number of gas nuclei in the liquid. . The microbubbles in the water and the solid microparticles in the water are the air nuclei that produce cavitation. In the river water or sea water in nature, the microbubbles are the main components of the air nuclei.

[0003] The basic principle of cavitation technology, one is the availability of the formation of holes, and the other is the local high pressure and high temperature induced when the cavitation bubble collapses, which can be used to affect the physical and chemical...
