摘要/Abstract

摘要： 针对水合物混合浆体中存在少量天然气的问题，设计了一种适合水合物混合浆体除气除砂的新型水力旋流器?双锥?内锥型水力旋流器，采用有限体积数值模拟方法研究了颗粒粒径、锥角组合、进口压力对固体颗粒和天然气分离效率的影响. 结果表明，固体颗粒粒径为50?90 ?m、天然气气泡直径为400?800 ?m、进口压力为4.3?7.3 MPa时分离效率最佳，最优的锥角组合为10o–5o.

Abstract: A double cone?inner cone hydrocyclone suitable for removing gas and sand in mixed slurry of natural gas hydrate was designed for the presence of natural gas in the mixed slurry of submarine natural gas hydrate. The effects of particle size, cone angle combination, inlet pressure on separation efficiency of solid particles and natural gas were studied. The results showed that under the conditions of the solid particle diameter 50?90 ?m, the natural gas bubble diameter 400?800 ?m and the inlet pressure 4.3?7.3 MPa, the optimum separation efficiency can be archived, the optimum cone angle combination was 10o–5o.

Key words: seabed nature gas hydrate, seabed separation, double cone-inner cone hydrocyclone, multiphase flow, CFD
