摘要
Abstract
For the problem of blockage in the inlet pipelines of the original parallel cyclone separator and in outlet pipeline of the gas riser,the influence of the structural types of the inlet pipeline of the parallel cyclone separator and outlet pipeline of the gas riser on the fluid inside the pipelines during coal dry distillation process was studied.The structure was optimized and compared with the original structure.The results show that increasing the bend angle and reducing the number of bends in the inlet pipeline can effectively reduce the overall pressure drop of the pipeline.Compared to the original pipeline structure,the optimized pipeline achieves a pressure drop reduction of approximately 75%.The use of Tee pipes prevents lower gas velocity on the outer wall of bends,thus avoiding particle deposition and blockage in low-speed areas.The adoption of tangential gas risers can significantly improve the low-speed areas and unstable flow problem caused by swirling,thus preventing particle accumulation.Extending the height of the blind-end pipeline can effectively reduce the influence of vortex on the flow field of the cyclone separator.Combined with a comprehensive analysis of the flow field and pressure drop,it is found that a blind-end height of 700 mm for the gas rise pipe is the most suitable.The overall system operation cycle in industry has been extended from 3 months to more than 6 months,with a pressure drop reduction of approximately 48%compared to the original structure.This research can provide guidance for the design and application of parallel cyclone separators in engineering.关键词
