Analysis of Problems Existing in Operation of Anion Exchangers
Combined with the specific operation of the chemical demineralization ion exchanger in this work area,the paper analyzes the phenomena of large fluctuation of water production due to different working conditions,poor raw water quality,unreasonable hydrophobicity recovery,reduction of effective resin in the ion exchanger leading to the decrease of periodic water production,and high conductivity after regeneration due to conductivity meter reasons and mixing of yin-yang resin.The corresponding solutions,such as unifying the regenerated liquid method,improving the pretreatment process and equipment maintenance,changing the direction of fixed expansion drain,replenishing resin in time,replacing the conductance meter electrode and separating the positive resin in the negative bed,are put forward,which are of great significance for the long-term stable and efficient operation of the ion exchanger.
