在低压锅炉的制水设备中,常见的是无中排装置低流速逆流再生式的和有中排装置压脂层气(水)顶压逆流再生式的固定床软化器。该项技术虽已得到普及应用,但真正发挥具有制水质量好、制水量大和大幅度降低食盐消耗作用的为数并不很多。针对这些问题,作者根据在百余台上述两种制水设备都采用低流速逆流再生技术所作经济运行工况反复调试的实践表明,只 In the low-pressure boiler water equipment, it is common to have low-flow non-mid-stream unit with a low-flow recirculation type and a medium-pressure tank (water) top pressure countercurrent regeneration type fixed bed softener. Although the technology has been popularized and applied, it is not many to really play the role of making good water quality, producing large quantity of water and reducing salt consumption drastically. In response to these problems, according to the author in the hundreds of units of both water-based equipment are used low-flow countercurrent regeneration technology for economic operation of the repeated commissioning practice shows that only
