Double-barrel gas-liquid separator

Abstract

The invention aims at providing a double-barrel gas-liquid separator. The double-barrel gas-liquid separator comprises an outer barrel body, and an inner barrel body which extends into the outer barrel body, wherein the lower end part of the inner barrel body is kept at the outer part of the outer barrel body; an impeller is mounted in the inner barrel body; a liquid draining area section is arranged at the outlet end of the inner barrel body; a liquid draining hole is formed in the liquid draining area section; a separator liquid phase guide outlet is formed in the lower end part of the outerbarrel body; a separator gas phase guide outlet which is a pipe extending into the outer barrel body is formed in the top part of the outer barrel body; a separating baffle plate is arranged in the outer barrel body at the lower part of the separator gas phase guide outlet, and the separating baffle plate is connected to the outer barrel body at the upper part through a separating baffle plate pulling rib; the outer barrel body at the upper part of the inner barrel body forms a gravity separating chamber through which a liquid phase flows back. The double-barrel gas-liquid separator organically combines three separating theories, including the centrifuging separating theory, gravity separating theory and collision separating theory; the double-barrel gas-liquid separator is small in size,and compact in structure and is capable of effectively separating gas-liquid mixtures in wide gas phase and liquid phase process.

Description

technical field [0001] The invention relates to a gas-liquid separator. Background technique [0002] Gas-liquid separation technology is widely used in the exploitation of offshore oil and gas resources. It is of great significance to develop a gas-liquid separator that is small in size, compact in structure, and can operate efficiently under wide flow and multi-flow patterns. [0003] At present, there are many kinds of gas-liquid separators that have been practically applied in actual industrial production. According to the separation principle, they can be divided into the following categories: gravity gas-liquid separator, centrifugal gas-liquid separator, collision gas-liquid separator and combination type gas-liquid separator. Gravity-type gas-liquid separator is a well-studied and well-developed separator. It is widely used due to its high reliability and convenient maintenance. However, it is limited by large structural size, long separation period, and limited pro...
