【摘要】：针对火电厂石膏旋流器运行中存在短路流现象,导致溢流跑粗的问题,设计一种环峰式溢流管结构的新型石膏旋流器,并通过实验方法研究了其工作性能。结果表明,同一压强下与普通石膏旋流器相比,新型石膏旋流器的生产能力提高5%,分离效率提高13%;同时底流质量浓度和分级效率均高于普通石膏旋流器的相应指标,能够有效地缓解短路流,减少溢流跑粗问题,结构简单,易于使用。
[Abstract]:Aiming at the problem of short circuit flow in operation of gypsum cyclone in thermal power plant, a new type of gypsum cyclone with ring-peak-type overflow pipe structure is designed, and its working performance is studied by experimental method. The results show that under the same pressure, the production capacity of the new type gypsum hydrocyclone is increased by 5 and the separation efficiency is increased by 13% compared with the common gypsum cyclone. At the same time, the concentration of bottom flow mass and the classification efficiency are higher than the corresponding indexes of the ordinary gypsum cyclone, which can effectively alleviate the short-circuit flow, reduce the overflow coarsening problem, simple structure and easy to use.
