Abstract

The invention relates to the technical field of gas-liquid separator parts, and in particular relates to a self-circulation two-stage axial gas-liquid separation cyclone tube. The self-circulation two-stage axial gas-liquid separation cyclone tube comprises a first straight tube section, a second straight tube section, a first flare tube section and a second flare tube section, wherein the first straight tube section is internally provided with two fixed cross blades used for converting axial-flow fluid into rotational-motion fluid; two ends of the first flare tube section are respectively flared, the tail end of the first straight tube section is inserted into the front end of the first flare tube section and is fixed therein through a U-shaped weld assembly, the front end of the second flare tube section is tubular, the tail end of the second flare tube section is flared, and the front end of the second flare tube section is inserted into the tail end of the first flare tube section and is fixed therein through a U-shaped weld assembly; the front end of the second straight tube section is inserted into the tail end of the second flare tube section and is fixed therein through a U-shaped weld assembly. The self-circulation two-stage axial gas-liquid separation cyclone tube is greatly enhanced in space adaptability, decreased in pressure drop and especially suitable for down hole and offshore platforms.

Description

technical field [0001] The invention relates to the technical field of gas-liquid separator components, in particular to a self-circulating two-stage axial gas-liquid separation swirl tube. Background technique [0002] The particularity of offshore oil and gas fields and offshore platforms puts forward new requirements for gas-liquid separation technology and separators in oil and gas gathering and transportation: firstly, the structure of the separator must be compact to meet the strict space requirements; secondly, the separation efficiency must be improved , to reduce processing costs. Based on the above two points, the compact separator using the principle of centrifugal separation has become the first choice. The most common compact separators are cyclone separators, rotary power separators, online rotary separators, etc., but most of these separators have gas overflow, and they are faced with excessive pressure drop or complex structure, and the moving parts are pron...
