目前,全国的固定床软水设备基本上都普及使用上了先进的逆流再生技术和低流速逆流再生技术。其共同特点是用手工按程序操作阀门来实现制取软化水。由于具有交换→失效→再生循环往复的周期性,制取软化水的盐耗直接影响制水成本。针对使用单位食盐消耗过多的情况,分析其原因,如何大幅度降低食盐消耗谈一些实践体会。
At present, the country’s fixed bed soft water equipment are basically used on the popular advanced countercurrent regeneration technology and low-flow countercurrent regeneration technology. Its common feature is the manual operation of the valve according to the program to obtain demineralized water system. Due to the cycle of exchange → failure → regeneration cycle, the salt consumption of demineralized water directly affects the cost of water. In view of the situation that the consumption of salt in the unit is excessive, some reasons why it is analyzed and how to reduce salt consumption drastically are discussed.
