the blade rectifier 4, the natural gas containing liquid plug or entrained liquid enters the blade rectifier 4 from the gas-liquid inlet with certain flow velocity, the medium disperses from the rectilinear motion to flow out along the arc direction of the blade, and then rushes to the inner wall of the equipment, in the collision process of the medium and the blade rectifier 4, the uneven liquid plug, gas-liquid mixed phase, liquid-in-gas, gas-in-liquid and the like in the pipeline are dispersed and broken, so that the preliminary separation of gas phase and liquid phase is realized, gas and liquid phase fluid is formed, the liquid contacts with the wall of the equipment, the flow direction is changed along the inner wall of the equipment or directly to enter the bottom of the equipment, and the gas is positioned in the upper area of the equipment and flows to the corrugated plate filler of the section collector;
