Operation principle of the present invention is described as follows:
The present invention is connected by upstream flange 10 with moisture gathering line, as shown in figure 3, the biphase gas and liquid flow of upstream passes through When of the invention, gland 4 moves upwards under differential pressure effect along guide rod 6, and biphase gas and liquid flow passes through gland 4 and annular water conservancy diversion pedestal 3 Between annular gap flow to downstream.The effect of buffer spring 8 be prevent from opening in high entrance gas-liquid flow velocity lower cover 4 it is too fast right Cross supporting frame 5 impacts damage.Because the outer rim of swirl vane 12 and the inwall of straight length 9 are brought into close contact, biphase gas and liquid flow exists By that will produce centrifugal motion during swirl vane 12, the larger liquid phase of density can be thrown toward wall, and the less gas phase of density exists Pipeline center is flowed, so as to form spiral flow.Because larger tangential velocity be present in spiral flow, under tangential shearing force, Its fluid-carrying capability strengthens, so as to which upstream hydrops is constantly carried along into downstream.The present invention the annular entrance channel of water conservancy diversion pedestal 3 be Gradual shrinkage structure, circulation area reduces when upstream incoming passes through entrance, the increase of biphase gas and liquid flow flow velocity, produces spiral flow ability and increases By force, liquid distance is taken so as to increase.
If fluctuating pipeline climbing section is longer, or inlet fluid flow rate is smaller, and liquid phase climbs one in the downstream of swirl vane 12 After set a distance, spiral flow fluid-carrying capability weakens, and liquid phase can return to the low-lying place of pipeline under gravity, cause discharge opeing to lose Effect.The check-valves 1 that the present invention uses can effectively prevent liquid-phase reflux, as shown in figure 4, when flowing back, gland 4 can in deadweight and It is descending along guide rod 6 under the Action of Gravity Field of withdrawing fluid, the outlet of final closed ring water conservancy diversion pedestal 3, so as to prevent liquid-phase reflux. Rubber ring 7 on gland 4 plays a part of sealing at this moment, prevents liquid from passing through the seam between gland 4 and annular water conservancy diversion pedestal 3 Gap leaks.After fluid passage closure, ducts upstream pressure is continuously increased, and gland 4 will be pushed open again after reaching critical value, now on Trip high speed incoming can re-form spiral flow in the case where the present invention acts on, and hydrops is continued to bring downstream pipe into.
As shown in figure 5, it is the working effect schematic diagram of the invention in pipeline.Upstream biphase gas and liquid flow after the present invention, Change of flow is spiral flow, fluid-carrying capability increase, gradually brings liquid into downstream line, spiral intensity of flow increases with duct length Add and constantly decay until disappearance, can not finally continue discharge opeing., can be in pipe in order to strengthen the control effect to hydrops and slug flow More playscript with stage directions inventions are arranged in road, pipeline is divided into several processing units, are produced again by the present invention before spiral flow disappears Raw spiral flow, continue to complete discharge opeing work.Due to effectively controlling backflow by check-valves 1, at rear, incoming is continuously replenished Under promotion, the liquid in processing unit is pushed to undulated pipeline top step by step, is finally discharged.
It can be seen that the hydrops in pipeline is taken away into low-lying place on the premise of present invention can be implemented in pipeline on-line production and prevented The hydrops being brought away from returns to the function at low-lying place, while reduces the length of slug flow liquid plug, makes the defeated process of collection more flat Surely, and the present invention also have it is simple in construction, it is easy to operate, it is safe and efficient the advantages of, be with a wide range of applications.
