摘　　要：以工业应用成熟的PV型高效旋风分离器为基础,从改善分离器的强度入手,对PV型分离器顶部及进气口等部位的结构进行改造,提出了一种拱顶、直切入口、升气管偏心的新型旋风分离器。介绍了新型分离器与PV型的冷模对比性能试验、分离效率与压降计算及其在粉煤灰熔聚流化床气化、聚丙烯聚合反应装置中的应用。结果表明,新型分离器结构强度和分离性能优良,适合在高温、高压工况下应用。Based on the maturely applied PV type high efficiency cyclone technology, the top and entrance structures of the PV type cyclone were amended, and a new-type cyclone with vault top, eccentric vortex finder and straight cut-in round inlet was put forward. The contrast tests, calculations of the efficiency and pressure drop of the new cyclone and new-cyclone applications for the dedust of the fluidized gasifier for high temperature coal gas and the polypropylene reactor for high pressure off-gas were presented. Results show that the new cyclone is good in both strength and separation performance,being applicable at high temperature and high pressure conditions.
