ABSTRACT

Current studies on improving the separation performance of cyclone separators focus on five aspects: i] geometry-structure optimization, ii] geometry-parameter optimization, iii] operation-parameter optimization, iv] operating-condition optimization, and v] internal component optimization. Many scholars work on the design and use of internal components in a cyclone separator to solve various industrial problems, but they seldom systematically classify these internal components. In the last 1999–2019 years, reports on such classification were relatively rare. Compared to the other four aspects, the internal components optimization has a unique advantage: when the equipment operation fails, there is no need to replace the original equipment, just the defective component, which greatly saves both maintenance and engineering expenses. In this review, several kinds of internal cyclone components are systematically summarized and classified, including their mechanism and usage effect. Furthermore, the trends in internal component development have also been prospected. Combined applications, development of new components and applications of new materials are the three main trends. In the future, internal components will be more diversified, detailed, precise and simplified. Finally, we expect that these developments will not only improve the separation efficiency and reduce the pressure drop but also satisfy requirements in environmental protection and process security.

摘要

目前关于提高旋风分离器分离性能的研究集中在五个方面：i] 几何结构优化，ii] 几何参数优化，iii] 操作参数优化，iv] 操作条件优化和 v] 内部组件优化。许多学者致力于旋风分离器内部组件的设计和使用以解决各种工业问题，但很少对这些内部组件进行系统分类。在过去的 1999-2019 年中，关于此类分类的报告相对较少。与其他四个方面相比，内部元件优化有一个独特的优势：当设备运行出现故障时，无需更换原有设备，只需更换有缺陷的元件，大大节省了维护和工程费用。在这次审查中，系统总结和分类了几种内旋风元件，包括其作用机理和使用效果。此外，还展望了内部组件的发展趋势。组合应用、新部件的开发和新材料的应用是三大趋势。未来，内部组件将更加多样化、精细化、精密化和简化。最后，我们希望这些发展不仅能提高分离效率和降低压降，还能满足环境保护和工艺安全的要求。组合应用、新部件的开发和新材料的应用是三大趋势。未来，内部组件将更加多样化、精细化、精密化和简化。最后，我们希望这些发展不仅能提高分离效率和降低压降，还能满足环境保护和工艺安全的要求。组合应用、新部件的开发和新材料的应用是三大趋势。未来，内部组件将更加多样化、精细化、精密化和简化。最后，我们希望这些发展不仅能提高分离效率和降低压降，还能满足环境保护和工艺安全的要求。
