Because of the aggregation forces are larger in the hard aggregations, the opposed jet of two nozzles were used for the dispersion of the hard aggregations. 对于硬团聚体颗粒，由于颗粒间的团聚力较大，可以采用对撞式双喷嘴对硬团聚体颗粒进行分散处理。
The maximum pressure drop and the operational pressure drop were investigated in a rectangular spouted bed with double nozzles by using air as spouting fluid. 摘要在双喷嘴矩形喷动床内，以空气为喷动气体，研究了最大喷动压降与操作压降的变化规律和影响因素。
