A multi-functional wide-flow high-efficiency gas-liquid separation device combining gravity and centrifugal technology

Abstract

The object of the present invention is to provide a multifunctional wide-flow high-efficiency gas-liquid separation device combining gravity and centrifugal technology, which includes a sleeve and a core tube. The inlet end of the core tube is located outside the sleeve tube, and the outlet end of the core tube extends into the To the inside of the sleeve, a support structure is set between the core tube and the sleeve, an impeller is installed in the core tube, a water retaining ring is set on the inner wall of the sleeve above the outlet end of the core tube, and a gas phase outlet is set at the upper end of the sleeve. The lower end is provided with a liquid phase outlet. The opening section of the present invention not only reduces the oscillation problem caused by the change of the gas-liquid two-phase flow pattern, but also enables the liquid phase to enter the annular descending space between the core tube and the casing as soon as possible, thereby improving the separation efficiency, preventing fatigue damage, and increasing the service life. The separation baffle can block the liquid droplets carried in the gas core and shunt them to the inner wall of the sleeve. The annular cavity formed by the water retaining ring and the inner wall of the sleeve can effectively prevent the liquid on the wall from rushing up too high and being carried by the gas. These structures The setting can effectively improve the separation efficiency.

Description

technical field [0001] The invention relates to a gas-liquid separation device. Background technique [0002] Gas-liquid two-phase flow widely exists in many fields such as power, nuclear energy, petroleum, chemical industry, etc. In order to meet the requirements of the process, ensure the safety of the system operation or improve the production efficiency, it is often necessary to separate the gas phase and the liquid phase. [0003] At present, the gas-liquid separator widely used in the industry is mainly based on the density difference between the gas phase and the liquid phase to achieve gravity separation or centrifugal force separation. For the gravity separator, although the structure of the equipment is relatively simple, the equipment size is large, the separation period is long, and the efficiency is low. When the gas flow rate is too high, it is easy to cause secondary carryover problems, so it is suitable for low flow rate conditions (“ Gravity separation devi...
