An overview of novel geometrical modifications and optimizations of gas-particle cyclone separators

A gas-particle cyclone separator is an economical device for removing particulate solids from a gas system, which is widely utilized in industrial applications. This review mainly focuses on the recently reported advances in performance improvement by conducting novel geometrical modification and optimization of gas-particle cyclone separators. The effect of each main parameter on cyclone performance was comprehensively discussed and summarized. Novel geometrical modifications of gas-particle cyclones are classified into four categories: vortex finder configuration, inlet configuration, cyclone body configuration, and dust collector configuration. With consideration of the complexity of cyclone structure, commercial potential, manufacturing cost, and performance improvement capability, the novel design of slotted vortex finder (SVF), integrated compact-bend cyclone (ICBC), gas cyclone-liquid jet separator, and cyclone with a shunt device (ECSD) are discussed. Moreover, the recent progress in global optimization of gas-particle cyclone separator for performance improvement is comprehensively summarized and discussed. At last, the status of relevant research field is estimated by strengths, weaknesses, opportunities, and threats (SWOT) matrix, which is expected to provide some meaningful experiences and inspirations for the future development of gas-particle cyclone separators.
