Compact type in-line liquid separator

Abstract

The invention relates to a compact type in-line liquid separator. The compact type in-line liquid separator comprises a gas inlet tube, a vortex generator, a separating cavity, a gas discharge tube, a liquid discharge tube and a liquid-level control valve, wherein the gas inlet tube, the vortex generator, the separating cavity and the gas discharge tube are connected by a flange in sequence; a guide vane of the vortex generator is in tight fit with a vortex generator housing; the guide vane can whirl after a gas-liquid mixture flows through the guide vane in the housing; the liquid discharge tube is connected with the tail end of the separating cavity, and the liquid-level control valve is mounted at the tail end of the liquid discharge tube. The liquid separator is mainly used for separating a liquid in the gas-liquid mixture( with a gaseous phase as a main body), so that the compact type in-line liquid separator, which is simple in structure, convenient for mounting, relatively low in pressure drop and high in separating efficiency, can be provided for the fields of offshore platforms, deepwater or ultra-deepwater oil and gas development (petroleum, natural gas, chemical engineering, biology and environmental protection), and the like. The device can be mounted and operated under a condition of complex environment and a limited space, can be used for effectively removing the liquid in the gas, and is high in reliability.

Description

technical field [0001] The invention relates to the field of gas-liquid separation equipment, in particular to a compact inline dehydrator. Background technique [0002] Cyclone separators have been widely used in mineral processing, petroleum, chemical industry, light industry, environmental protection, medicine, textile and many other industrial fields because of their advantages such as high separation efficiency, small equipment size and suitable for long-term operation. Gas-liquid cyclone separation technology is an efficient multi-phase fluid separation technology. Its principle is to use the density difference between two or more phases under the action of centrifugal force to achieve two-phase or multi-phase separation. According to the working principle, the gas-liquid cyclone separator is divided into column type cyclone separator, axial flow guide vane type gas-liquid cyclone separator, swirl plate type gas-liquid separator, spiral vane type gas-liquid separator, ...

AI Technical Summary

Problems solved by technology

[0005] Based on the problems existing in the above-mentioned prior art, the present invention provides a compact inline dehydrator, which can overcome the shortcomings of existing separators such as bulky volume, excessive pressure drop, complex structure, and easy failure of moving parts. Simple structure, easy installation, low pressure drop, high separation efficiency, can be used in offshore platforms, deep water or ultra-deep water oil and gas development (petroleum, natural gas, chemical, biological and environmental protection) and other fields to separate gas in complex environments and space constraints Liquid phase in a liquid mixture (gas phase as the main body)
