G50LDD Type Anti-Syphoner Liquid Down Comer
G50LDD型双体抗虹吸短路降液器
Novel G50LDD type anti-syphoner liquid down comer proprietarily assembled with manifolds, switches, flanges, pads, bolts and nuts, has been engineering-calculated and designed through Novel Accurate Calculation & Design Platform on Dynamic Separation Technologies in order to upgrade the conventional structure of double-tubes plus drums under swing operation conditions. When the mixed flows with phases of gas/liquid/solid reach the Novel G50LDD type anti-syphoner liquid down comer, it should switch and discharge the heavy phase flow outside and at same time prevent the outside heavy phase flow against penetrating inside as per the switch value given by Bernoulli Flow Theory to achieve the resistance of syphonage frequently occurring in the conventional poly-tubes plus drums under swing operation conditions.
诺卫技术公司G50LDD型双体抗虹吸短路降液专有技术设备，通过诺卫技术公司精准动力学分离技术工程化计算和组态设计系统平台完成技术方案，由降液管汇、气封开关、法兰、垫片和螺栓螺母等紧固件构成，用于技术升级改造传统结构的双降液管和液封筒以应对实际复杂多变操作工况。当气液固混合物相流进入G50LDD型抗虹吸短路降液器，在达到贝努力流体理论计算值即启动气封开关向外排放重相质流体同时阻挡外部轻相质流体短路窜入降液器，从而防犯传统结构多组降液管和液封筒在实际复杂多变操作工况下频繁发生的虹吸短路问题。
