As shown in fig. 2 and 3, the flow guiding wall 15 guides the fluid entering the housing 11 from the fluid inlet 12 to flow in a rotating trend in a circular configuration, and the gas components will flow to the gas outlet 131 through the structure inside the housing by the difference of centrifugal force between the components, and in particular, in order to reduce the local pressure of the gas in the channel, a gas outlet 132 with smaller exhaust capacity can be added before the gas outlet 131; the components of the liquid droplets will adhere to the side walls 102 and the flow guide wall 15 during the flowing process, and the condensed liquid will be collected to the bottom 103 of the housing under the action of gravity, wherein the bottom 103 of the housing is in a slope or cone structure with high periphery and low middle, because of the structure of the bottom 103 of the housing, the liquid will flow to the liquid outlet 14, which is provided with the umbrella-shaped diaphragm 16, and the umbrella-shaped diaphragm 16 can keep the liquid flowing in one direction even if the liquid in the bottom 103 of the housing is discharged, usually to the liquid tank.
As shown in fig. 4 and 5, the flow guide wall may be realized by a spiral flow guide wall 151, which has extensibility.
The flow guide wall can also be realized by a structure of a hollow chamber (not shown in the figure), and the hollow chamber can improve the sealing performance of the fluid passage and can realize the combined application of the fluid passage.
As shown in fig. 4 to 6, between the fluid inlet 12 and the guide wall 151, an arc-shaped baffle 17 may be arranged, which may buffer, regulate the flow velocity and direction of the fluid, so that the flow of the fluid in the housing is better guided.
