离子交换树脂具有交换能力及其他一系列优良的性能，为付诸实用，宜采用动态连续交换法及相应的装置，对要处理的电解质溶液进行交换、分离、浓缩、吸附。经研究、设计及实用表明，装填有离子交换树脂的柱或塔最为有效。这种柱或塔被称为树脂床，亦常称为交换柱(exchange column)、交换塔(exchange tower)。
用脱矿质器的另一个问题是，小的树脂粒常常逸出树脂床而进入水流。
Another problem with demineralizers is that small resin particles are often dislodged from the bed and enter the water stream.
所有的树脂床对温度都有要求，因此当温度超过预定值时，下泄流将旁通净化床运行。
All of the ion exchanger resins are temperature sensitive; therefore, a temperature diver valve bypasses letdown flow if the letdown heat exchanger outlet temperature rises to a predetermined value.
详细介绍了树脂床工作过程和酸净化装置的工作原理及工艺流程，对酸净化装置投入前后的酸耗量做了对比。
The working process of resin bed and working principle of acid purification unit and flowchart are described particularly. Making comparison of acid consumption of using it before and after.
