前言逆流再生工艺的推广及应用,是锅炉水处理技术的一次革命。但长期以来,人们大都对“空气顶压法”、“低流速法”较为重视,而对负压法”不那么理解,甚至要问“既然已有”空气顶压法”和“低流速法”互补优缺,那何必要搞“负压法”呢?其实不然“负压法”确有它的独到之处。例如,它与空气法相比具有节约投资及运行费用的突出优点。“低流速法”虽不需空气系统,但也只能限入阳床。这主要因阳床树脂比重大,再生液粘度低所
Preface The promotion and application of countercurrent regeneration technology is a revolution in boiler water treatment technology. However, for a long time, people mostly pay more attention to the “Air Top Pressure Method” and “Low Flow Rate Method”, but do not understand the negative pressure method. They even ask “Since the” Top Air Pressure Method “and” “Complementarity, why then engage in” negative pressure “? In actual fact,” negative pressure law “does have its unique features. For example, it has outstanding advantages over the air method in terms of investment and operating costs. Although the ”low flow rate method" does not require an air system, it can only be confined to a sunny bed. This is mainly due to the proportion of positive resin bed Yang, regenerative fluid low viscosity
