DETAILED DESCRIPTION
[0012] In order to better understand the utility model, the utility model is further described below in combination with the drawings.
[0013] In the description of the utility model, it should be explained that the positions indicated by the terms "upper", "lower", "left", "right" and the like are based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the utility model and simplifying the description.
[0014] Figure 1 The overall layout of the utility model is shown in the figure. The utility model comprises an inner and outer steady flow pipeline 1, an inner and outer cyclone generator 2, an inner and outer Laval nozzle 3, an inner and outer liquid collecting cavity 4, an inner and outer liquid discharging port 5, and an inner and outer diffuser 6. The inner and outer steady flow pipeline 1, the inner and outer cyclone generator 2, the inner and outer Laval nozzle 3, the inner and outer liquid collecting cavity 4, the inner and outer liquid discharging port 5, and the inner and outer diffuser 6 are arranged in sequence from top to bottom. The inner and outer cyclone generator 2 is installed inside the inner and outer steady flow pipeline 1, the outer cyclone generator is fixedly connected together between the inner and outer steady flow pipelines, and the inner cyclone generator is installed inside the inner steady flow pipeline. The double channels are coaxially arranged. The outer steady flow pipeline of the inner and outer steady flow pipeline 1 is an annular space. The inner cyclone generator in the inner and outer cyclone generator 2 is provided with blades and both ends are ellipsoids; the blades are equidistantly arranged between the ellipsoids and the inner steady flow pipeline. The inner and outer Laval nozzle 3 is provided with the inner and outer liquid collecting cavity 4 and the inner and outer liquid discharging port 5 at the tail end. The inner and outer steady flow pipeline 1, the inner and outer cyclone generator 2, the inner and outer Laval nozzle 3, the inner and outer liquid collecting cavity 4, and the inner and outer diffuser 6 are all made of corrosion-resistant metal. The inner and outer diffusers 6 are coaxially connected with the inner and outer Laval nozzle 3 and are divided into primary and secondary diffusers.
[0015] In the separation process of gas-liquid two-phase, the design of inner and outer channels reduces the settling distance of condensation droplets, and improves the condensation efficiency. The gas-liquid two-phase mixed fluid enters the inner and outer steady flow pipes from the inlet, and after passing through the inner and outer cyclone generators, the gas-liquid two-phase mixed fluid forms cyclone motion to obtain tangential velocity. When the mixed fluid passes through the inner and outer Laval nozzles, the mixed fluid forms supersonic fluid through adiabatic expansion. At this time, a low-pressure and low-temperature environment is formed in the pipe, and the liquid droplet condensation nucleation phenomenon occurs. The liquid droplet gradually grows around the liquid nucleus to form the mixed fluid of gas and condensation liquid droplets. After the mixed gas flow passes through the expansion section of the Laval nozzle, under the condition of the same centrifugal acceleration, the liquid droplets move forward along the wall, and the gas moves forward in the center of the pipe. After the separated liquid passes through the end of the Laval nozzle pipe, the accumulated liquid flows out from the liquid outlet, and the separated dry gas flow still has a high speed, which passes through the two-stage speed reduction and pressure increase of the diffuser, and then is discharged from the dry gas outlet.
