新型脉冲式离子交换器研究

Research for new-type pulse ion-exchanger

研究用于提取柠檬酸的新型脉冲式离子交换器工作原理及结构形式。研究了脉冲喷射时间对树脂层压力降和离子交换器流体流量的影响,其结果是:脉冲喷射可降低离子交换器压力降,提高离子交换器的流量,同时可有效防止由于树脂吸胀引起的树脂失效,使离子交换器长期稳定运行。

This paper studies a new-type ion-exchanger used to adsorb citric acid, and expounds its operating principle and structure form. Studied the influence of pulse jet time to the resin layer differential pressures and the discharge of ion exchange. The result is that a pulse jet can reduce the differential pressure of ion-exchanger, at the same time, it can increase the discharge of ion-exchanger, which can effectively prevent ion-exchanger failure caused by resin absorption expansion, making the ion-exchanger long-term and stability operation.
