Themixing cavity 23a and thebackflow cavity 23 are arranged, so that the flow state of backflow and mixed fluid is more stable in actual use, and the working reliability is effectively improved.

In addition to themixing chamber 23a and thereturn chamber 23 provided in fig. 1 and 2 ofembodiment 1 and 2, themixing chamber 23a may be provided independently in the high-pressurefluid treatment tank 2 without providing thereturn chamber 23, as shown in fig. 3 of embodiment 3, in which case the fluid flowing out of the turbine powerplant outlet pipe 14 does not enter thereturn chamber 23 first, but directly enters theejector pipe 242 of the turbine powerplant outlet pipe 14.
