| 摘 要： | 采用Fluent软件对加氢反应器中单个泡罩分配器的流体力学性能进行模拟，以BL型气液分配器为基础构型，通过改进其下降管和碎流板结构进行结构优化。结果表明，改进的气液分配器构型与原BL型气液分配器相比，喷洒面积增大255%，不均匀度减小30.19%，压降增大73.63%，综合性能优于原BL型气液分配器。

NUMERICAL SIMULATION AND STRUCTURE OPTIMIZATION OF DISTRIBUTOR IN HYDROGENATION REACTOR |
| |
| Abstract: | The hydrodynamic performance of the bubble distributor in hydrogenation reactor was simulated by Fluent software. The downcomer and the stream breaker of the BL gas-liquid distributor. were optimized in structure. It was found that the spray area increases by 255% and the non-uniformity reduces by 30.19% after optimization, but the pressure drop of the improved distributor is 73.63% higher than the BL type distributor. The results indicated that the comprehensive performance of the new distributor is better than the prototype. |
