摘要
通过对旋风管的导向叶片、排气与排尘结构等3部分的重大改进与创新，开发了国产EPVC系列旋风管和最新的PDC型旋风管，同时还开发了具有独特防返混排尘结构的PIM型卧管式多管旋风分离器，目前这两项技术已在全国40多个炼油厂催化裂化装置上推广应用，经济效益显著。
The new EPVC series and PDC type high efficiency guide-vaned cyclone tubeswere developed on the improvements of the guide vanes, the exhaust tubes and the dust dischangeconfiguration. New PIM type multicyclone separator with horizontally installed PT-Ⅱ type cyclone tubes, of which the patented anti-backmixing cone was characteristic, was also developed.All of them were used successfully with significant economic benefits in more than 4o sets of fluidized catalytic cracking units.
