The lower part of the liquid separating pipe 4 is provided with densely distributed and fine liquid separating holes.
As shown in fig. 1 and 2, the gas-liquid channel 9 is composed of an upper-layer wave-shaped fixed disk 5 and a lower-layer wave-shaped rotating disk 6, the wave direction of the upper-layer wave-shaped fixed disk 5 is the same as that of the lower-layer wave-shaped rotating disk 6, the inner side of the upper-layer wave-shaped fixed disk 5 is welded and fixed with the liquid separating pipe, and the outer side of the upper-layer wave-shaped fixed disk is welded and fixed with the outer edge of the rotating disk; the bottom of the lower layer wave-shaped rotating disk 6 is fixedly connected with the top surface of the rotating disk in a marking way and rotates together with the rotating disk.

The rotating shaft speed is 200-2000 rpm. Through rotating, the vapor-liquid exchange efficiency is fully improved.
