备注

旋流气液分离器能够实现高气速、高气液比工况下的气液分离,从而满足降本增效的要求。通过调研国内外水下旋流气液分离器的研究成果,对不同类型的水下旋流气液分离器进行了重点评述,从旋流场内液滴破碎机理、分离器内部流场参数等方面论述了水下旋流气液分离器的理论研究进展。结合工程实际需求,提出了水下旋流气液分离器研究中的不足及其未来的研究方向:建立水下旋流气液分离器的独立设计准则;进一步完善液滴在旋流场中破碎与聚合的理论研究;将旋流气液分离器与其他形式的分离器相结合,形成综合性的分离系统。(表1,参[50]

Gas-liquid cyclone separator can realize gas-liquid separation in the working conditions of high gas speed and high gas/liquid ratio and can satisfy national requirements on cost reducing and efficiency increasing. In this paper, domestic and foreign research achievements on undersea gas-liquid cyclone separators were investigated, and different types of undersea gas-liquid cyclone separators were mainly reviewed. Then, the theoretical research progress of undersea gasliquid cyclone separator was discussed from the aspects of the breakage mechanism of droplet in the swirling flow field and the internal flow field parameters of separator. Finally, based on the actual engineering demands, the disadvantages and future development direction of the researches on undersea gas-liquid separator were pointed out. It is recommended to establish an independent design criterion for undersea gas-liquid cyclone separator, further improve the theoretical researches on droplet breakage and coalescence in the swirling flow field, and combine the gasliquid cyclone separator with other forms of separators to establish an integrated separation system.
