Technical Field

Background
In recent years, a compact Gas-liquid separator, namely a tubular column type Gas-liquid cyclone separator (GLCC) is more suitable for severe underwater conditions due to the advantages of short material retention time, high separation efficiency, large treatment capacity, small occupied area, lower cost, strong pressure bearing capacity and the like, and gradually replaces a gravity separator in the field of deep sea oil and Gas development. GLCC is a novel oil-gas separator based on centrifugal separation, and has a simple and ingenious structure. It is mainly composed of an inclined inlet pipe, a vertical cylinder, a gas-phase outlet pipe and a liquid-phase outlet pipe. The gas-liquid mixed flow firstly enters an inclined inlet pipe, and a gas-liquid stratified flow is formed in the inclined inlet pipe, so that a mixture is pre-separated; the connection part of the inclined inlet pipe and the vertical cylinder is provided with a tangential convergent nozzle, so that gas-liquid mixture subjected to swirl making and acceleration forms gas-phase and liquid-phase two-way rotational flow respectively at the upper part and the lower part of the vertical cylinder, liquid drops in the gas-phase rotational flow are thrown to the side wall and finally flow downwards from a liquid-phase outlet under the combined action of centrifugal force and gravity, and bubbles in the liquid-phase rotational flow are gathered to the central axis while rotating and are finally upwards discharged from the gas-phase outlet at the top. This separation mechanism, in which centrifugal gravitational forces are coupled to each other, is clearly more efficient in separation than conventional gravity separators.
Although the existing tubular column type gas-liquid cyclone separator can carry out gas-liquid separation, in practical application, a small amount of liquid phase is mixed with gas phase at the separation position or a small amount of gas phase is mixed with liquid phase, so that the separation purity is influenced. Therefore, the existing tubular column type gas-liquid cyclone separator needs to be upgraded to improve the gas-liquid separation efficiency and the separation purity.
