摘要：
Venturi inlet configuration is important for the circulating fluidized bed desulphurization tower. By using numerical simulation, the gas flow fields of the circulating fluidized bed desulfurization reactor with one venture and multi-venturi were investigated. The results showed that the gas flow field was obviously uneven and there was a longer inlet affected zone in the circulating fluidized bed desulphurization tower with the original design condition of only one venture. The gas flow field with the structure of multi-venturi group was obviously uniform. Based on this configuration, to revise proper diameter distribution for the venture tube group the gas flow field became more uniform. The inlet structure optimization based on the velocity non-uniformity could obtain more uniform flow field and shorter inlet affected zone in desulphurization tower than based on the flow rate deviation factor.
