中文摘要:
      循环冷却水浓缩倍数的提升会加剧换热设备的结垢,同时,工业规模循环冷却水系统的循环冷却水量和排污量也严重制约着阻垢剂和除垢方法的选择。将阻垢剂划分为传统化学阻垢剂、基于石化产品的绿色阻垢剂、基于生物提取物的绿色阻垢剂三大类,针对阻垢剂的类型和特点进行了分析总结,介绍了阻垢剂的研究现状并分析了阻垢剂的发展趋势;简述了常用的物理除垢方法及其研究进展,对换热设备的损伤和较低的除垢能力是这类方法难以忽视的问题;阻垢剂和物理方法组合使用的相关研究表明物理方法会显著影响阻垢剂的性能。结合循环水系统除垢的研究现状,对除垢的技术发展进行了总结和展望,提出了对阻垢剂和除垢方法使用的建议以及解决相关问题的新思路。
英文摘要:
      Abstract: With the increase of concentration multiple of circulating cooling water, the scaling of heat exchange equipment will aggravate. At the same time, the selection of scale inhibitors and descaling methods is severely restricted by the amount of circulating cooling water and blowdown of industrial scale circulating cooling water systems. Scale inhibitors are divided into three categories: traditional chemical scale inhibitors, green scale inhibitors based on petrochemical products and green scale inhibitors based on biological extracts. In this paper, the type and characteristic of scale inhibitors are analyzed and summarized, and the research status and development trends of scale inhibitors are introduced. Common physical descaling methods and research progress are briefly described, which the scale inhibition ability is relatively low and is easy to cause damage to the equipment. Some studies show that physical methods can significantly affect the performance of scale inhibitors when scale inhibitor are used in combination with physical methods. Combined with the current research situation of descaling in circulating water system, the development of descaling technology is summarized and prospected, and the suggestions for the use of scale inhibitors and descaling methods and new ideas for solving the scaling problems are put forward.
