凡是采用低流速逆流再生技术制备锅炉给水的固定床离子交换器,第1个周期都必须应用大反洗→再生→小反洗→正洗→制水5步程序操作运行。当这个周期的离子交换树脂失去制水能力之后,从第2个至第16个计14个周期必须应用再生→小反洗→正洗→制水4步程序操作运行。不论是少周期的5步程序操作法,还是多周期的4步程序操作法,因为再生→小反洗→这2步程序的再生液和小反洗水都是用泵从离子交换器底部输进,并以一定 Any use of low-flow countercurrent regeneration technology to prepare boiler feed water fixed bed ion exchanger, the first cycle must be applied backwash → regeneration → small backwash → wash → water 5-step program operation. When the ion exchange resin of this cycle loses its ability to make water, it must be regenerated → small backwash → positive wash → water making 4-step program operation from the 14th cycle of the second to the 16th. Whether it is a less cycle 5-step process, or a multi-cycle 4-step process because regeneration → small backwash → the two-step regeneration solution and the small backwash are pumped from the bottom of the ion exchanger Enter, and with certain
