Hydrodynamic three-stage cavitation device

Abstract

A hydrodynamic three-stage cavitation device belongs to the field of fluid cavitation and comprises a water inlet A, a water outlet B, an air inlet C, a pore plate 1, a circular-truncated-cone-shapedpore plate 2, circular truncated cone-shaped pore plate holes 3, a cylinder 4, a first annular hole 5, a baffle element 6, a second annular hole 7, a long rod 8, an end cover 9, a handle 10, a cavitation pipe body 11 and a circular truncated cone-shaped pore plate bottom hole 12. The device is characterized in that the distribution of the circular holes 3 and the shape of the axial section of thebaffle element 6 can be changed, the circular-truncated-cone-shaped pore plate 2 and the baffle element 6 are matched with the long rod 8 and can coaxially move along with the long rod 8, and then thepositions and the strength of the three cavitation fields are changed; the pore plate 1 is provided with an air inlet, and a large number of microbubbles are mixed in water inlet fluid; and enough gas nuclei are provided for three cavitation fields at the downstream. A three-stage cavitation structure is adopted, so that the defect of insufficient cavitation is overcome, and more energy is released; The cavitation device is simple in structure, convenient to operate and low in cost, the cavitation efficiency is effectively improved, and the cavitation device has very considerable developmentand application prospects.
