蒸发空冷器结垢原因分析及化学清洗效果的评价

摘要

通过对结垢机理的化学分析和实验室试验分析，确定高炉蒸发空冷器换热管结垢原因并制定清洗方案。通过机械清洗和化学清洗达到除垢的目的，有效地降低了水温，节约了水量。%Through chemical analysis and laboratory test of scaling mechanism in heat exchanger tube of blast furnace evaporative air cooler, the causes of the scaling were deter-mined and a cleaning scheme was drawn up. Scaling was removed by mechanical and chemi-cal cleaning, which effectively reduced water temperature and saved water consumption.
