| 摘 要： | 某焦化厂经过多次扩容后,冷却水系统容量没能跟上发展,冷却能力远低于运行需求,新水(自来水)消耗量远远高出国内外同行业水平。对其水系统进行改造,即新增两台容量为600m3/h的冷却塔、修复当前冷却效果已经较差的2台的冷却塔,将循环冷却水温降下来,以减少循环冷却水系统的排水量和补充水量;增设废水回收利用管网,将原排放的废水用于熄焦补充水,以节省熄焦补充水对新水的消耗,多余的废水引入到集团公司炼铁厂使用。通过改造,焦化厂吨焦耗水从9.03m3降至3.21m3,每年节约用水量约为6×106m3,集团公司年节约用电约2×106kWh,节约运行费用约300万元,获得了较好的经济效益和环境效益。

| Abstract: | A coking plant extended many times,and its capacity of the cooling water system is not match with it,the consumption of new water is much more than that used by others in the same industry.The water system renovation is addressed for an extended coking plant.The installation of two 600 m3/h cooling towers and restoration the existing two cooling towers are to promote the cooling capacity so that the amount of discharge and feed could be reduced.At the same time,the pipe net for waste water reutilisation is ... |
