Publication number: 20240017275Abstract: The present disclosure provides a cyclone separator and a cyclone separation method. The cyclone separator includes a shell and a core tube. An upper end of the shell is provided with a gas inlet. A lower end of the shell is provided with a shell outlet. An opening at a lower end of the core tube is provided inside the shell. The lower end of the core tube is provided with a baffle structure, and at least a portion of the baffle structure extends vertically. By providing the baffle structure, the present disclosure can cut off the flow path of the short-circuit flow and the radially centripetal moving gas flow such as the centripetal flow in the particle spiral band area, weaken the short-circuit flow, the inner vortex flow and the precessing vortex core, thus improving separation efficiency of fine particles with particle diameters of 1 ?m to 10 ?m.Type: ApplicationFiled: January 5, 2023Publication date: January 18, 2024Inventors: Sihong GAO, Yiping FAN, Chunxi LU
