摘要：【中文】本发明公开了一种气液分离器与气液分离方法。气液分离器设有气液分离器筒体(10)，其内设有螺旋分离器(5)。螺旋分离器筒体的上部设有螺旋分离器入口管(51)，底部设有第一导液管(2)。螺旋分离器筒体的轴心线区域设有升气管(6)垂直管段，升气管垂直管段与螺旋分离器圆筒形筒体之间设有螺旋板(52)。上下相邻两圈螺旋板之间形成螺旋通道，螺旋分离器入口管的出口与螺旋通道的顶部入口相通。螺旋分离器筒体与气液分离器筒体之间设有支撑板(9)，支撑板上设有扭带分离器(7)和第二导液管(8)。本发明公开了采用上述气液分离器进行气液分离的方法。本发明可用于石油化工等行业中的多种工艺过程，平稳高效地进行气液分离。 【EN】The invention discloses a gas-liquid separator and a gas-liquid separation method. The gas-liquid separator is provided with a gas-liquid separator cylinder body (10) in which a spiral separator (5) is arranged. The upper part of the cylinder body of the spiral separator is provided with a spiral separator inlet pipe (51), and the bottom of the cylinder body of the spiral separator is provided with a first liquid guide pipe (2). The axial lead area of the cylinder body of the spiral separator is provided with a riser (6) vertical pipe section, and a spiral plate (52) is arranged between the riser vertical pipe section and the cylindrical cylinder body of the spiral separator. A spiral channel is formed between two adjacent circles of spiral plates, and an outlet of an inlet pipe of the spiral separator is communicated with an inlet at the top of the spiral channel. A supporting plate (9) is arranged between the cylinder body of the spiral separator and the cylinder body of the gas-liquid separator, and a twisted belt separator (7) and a second liquid guide pipe (8) are arranged on the supporting plate. The invention discloses a method for gas-liquid separation by adopting the gas-liquid separator. The invention can be used for various technological processes in the industries of petrochemical industry and the like, and stably and efficiently performs gas-liquid separation.
