Multifunctional wide-flow high-efficiency gas-liquid separation device combining gravity and centrifugal technology

Abstract

The invention aims to provide a multifunctional wide-flow high-efficiency gas-liquid separation device combining gravity and centrifugal technology. The device comprises a sleeve and a core tube, wherein the inlet end of the core tube is located outside the sleeve, and the outlet end of the core tube extends into the sleeve; a support structure is arranged between the core tube and the sleeve, animpeller is mounted in the core tube, a water retaining ring is arranged on the inner wall of the sleeve above the outlet end of the core tube, a gas phase lead-out port is formed in the upper end ofthe sleeve, and a liquid phase lead-out port is formed in the lower end of the sleeve. By means of an opening section, oscillation caused by change of the gas-liquid two-phase flow pattern is weakened, liquid phase can flow into the annular descending space between the core tube and the sleeve as soon as possible, and accordingly, separation efficiency is improved, fatigue damage is prevented, andthe service life is prolonged; liquid droplets carried in the gas core can be blocked by a separation baffle and diverted to the inner wall surface of the sleeve, and liquid on the wall surface can be effectively prevented from going uprush too high and being carried by gas due to an annular cavity formed by the water retaining ring and the inner wall of the sleeve. Therefore, separation efficiency can be effectively improved by the structures.

Description

Technical field [0001] The invention relates to a gas-liquid separation device. Background technique [0002] Gas-liquid two-phase flow is widely present in many fields such as power, nuclear energy, petroleum, chemical industry, etc. In order to meet process requirements, ensure system operation safety or improve production efficiency, it is often necessary to realize the separation of gas and liquid phases. [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 separation. For gravity separators, although the structure of the equipment is relatively simple, the equipment size is larger, the separation period is longer, 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 conditions (" Gravity separation device for water treatment", CN101218006...
