The invention discloses a two-stage cavitation generator with a composite structure. The two-stage cavitation generator comprises a Venturi tube and an orifice plate. The exterior of the Venturi tubeis tubular, and the Venturi tube is successively composed of an inlet end, a gradual contraction section, a throat section, a gradual enlargement section and an outlet end. The orifice plate is provided with several pore channels, which are arranged in the throat section. The two-stage cavitation generator is an integrated two-stage cavitation generator with the orifice plate and the Venturi tubenested. Through simulation verification, the two-stage cavitation generator can complete two cavitation processes when boundary conditions are certain, has higher cavitation efficiency than a traditional single-stage cavitation generator, and has a better cavitation effect and larger cavitation area to release more energy in comparison with a combined cavitation generator formed by direct connection of an orifice plate and a Venturi tube. By combining advantages of a traditional single-stage cavitation generator and optimizing the structure of the combined cavitation generator, the optimum structure value relation is brought forward. The two-stage cavitation generator has engineering development value and anapplication prospect.
