Combined high-efficiency gas-liquid separator

Abstract

The invention achieves the purpose by providing a combined high-efficiency gas-liquid separator. The combined high-efficiency gas-liquid separator comprises an outer barrel, an inner barrel and a corebarrel, wherein the inner barrel stretches into the outer barrel; the lower end part of the inner barrel stays outside the outer barrel; a primary impeller is mounted on the middle part of the innerbarrel; a secondary impeller is mounted on the top of the inner barrel; a liquid draining section is arranged on the inner barrel between the primary impeller and the secondary impeller; liquid draining holes for communicating the internal space of the inner barrel and the internal space of the outer barrel are formed in the liquid draining section; a separator outer barrel upper chamber for dropping a liquid phase is formed between the secondary impeller and a separator gas phase outlet; the core barrel is arranged inside the separator outer barrel upper chamber; separating pore plates are mounted between the core barrel and the outer barrel; a water baffling ring is mounted at the lower end of the core barrel; separator liquid phase outlets are formed in the lower end part of the outer barrel; the separator gas phase outlet is formed in the top of the outer barrel. The combined high-efficiency gas-liquid separator is compact in structure and small in volume occupancy, and can achieveefficient and fine separation of a gas-liquid mixture under the conditions of wide liquid flow and gas content.

Description

technical field [0001] The invention relates to a gas-liquid separator, in particular to a gas-liquid separator in the field of nuclear energy. Background technique [0002] During the operation of nuclear power plants, gas-liquid mixtures need to be separated in many equipment such as steam generators. Due to the difficulty of on-site maintenance and the small space, the existing gas-liquid separation equipment has problems such as single applicable flow pattern and narrow flow process, and it is impossible to complete the gas-liquid separation under multi-flow patterns, especially under unstable flow patterns, by relying on a single separation principle. Efficient separation of two phases. Therefore, it is of great significance to develop a gas-liquid separator that has a compact structure, a small footprint, and integrates multiple separation principles to achieve efficient separation of gas-water mixtures. [0003] Most of the current gas-liquid separation equipment on...
