Expanding the Controllable Range of the Mean Residence Time Ratio of Polydisperse Particles in Multiple-Chamber Fluidized Beds: A Coarse-Grained CFD-DEM Study
摘要：The residence time of polydisperse particles is crucial for their simultaneous conversion in a fluidized bed. This study focuses on regulating the residence time of polydisperse particles to expand their controllable range by optimizing the reactor design and operation step-by-step. The mean residence time (MRT) ratio of coarse and fine particles (t(p)(c)/t(p)(f)) increased significantly with increasing elutriation pipe width of the multiple-chamber fluidized bed, thus enabling the MRT ratio to exceed (d(p)(c)/d(p)(f))(2); however, the MRT ratio of medium and fine particles (t(p)(m)/t(p)(f)) is only slightly exceeded d(p)(m)/d(p)(f). Moreover, by further optimizing the elutriation pipe gas velocity, the latter can be adjusted to be exceed (d(p)(m)/d(p)(f))(1.5). Finally, t(p)(c)/t(p)(f) and t(p)(m)/t(p)(f) can be simultaneously adjusted to exceed (d(p)/d(p)(f))(2) by increasing the number of elutriation pipes. Therefore, present study enables the controllable range of the MRT ratio of polydisperse particles covering from d(p)/d(p)(f2) to (d(p)/d(p)(f))(2) that meets the required reaction time ratio of different particle sizes, which is of great interest for realizing the synchronous conversion of polydisperse particles.
