离子交换塔树脂转移管管径选择及树脂转移工艺试验研究

针对离子交换装置的泥沙及成本问题,设计制造试验装置.进行试验测试对比三种方案中树脂在装置中转移时的水流量和转移时间,得到最优方案.液体在装置中能较好地形成湍流,有效地冲散了树脂层,解决了泥沙问题,防止了因树脂结块而影响吸附效率.还能兼顾固定床投资成本、运行成本低和移动床操作简单的优点.

Experimental Study on Diameter Selection of the Ion Exchange TowerResin Transfer Tube and the Resin Transfer Technology

According to the problem of sediment and high cost,an experimental device has been designed and manufactured.Then some experiments were done in three different schemes.The water flow and time of the resin transferring in the device were compared and the optimal solution was obtained.The liquid in the device could form to turbulence well,effectively break up the resin,solve the sediment problem and prevent reducing adsorption efficiency from agglomeration of the resin.And the new device could give consideration to the low fixed bed investment and operation cost of fixed bed and the advantages of simple operation of moving bed.
