连铸冷却水复合膜过滤器技术的研发

为了钢铁工业节能减排、降低水污染和吨钢耗水量,进行了转炉炼钢连铸冷却水过滤器技术的研发,成功开发了一种以多孔PVC陶瓷复合管为过滤元件的过滤器装置。对由多孔PVC陶瓷复合管过滤器过滤的污泥进行检测,可知多孔陶瓷复合过滤管具有很好的分离效果。检测过滤前后的水质,发现过滤后水的浊度和悬浮物含量显著降低,水质达到指标要求。通过工业试验研究和近3年的实际应用,确定了多孔PVC陶瓷复合过滤设备的最佳操作条件和反冲洗条件。

Technology of microporous multiple tube membrane filter for purifying cooling water in continuous casting process

In order to achieve energy conservation and emission reduction and reduce water pollution and water consumption per ton steel in iron and steel industry, technology of filter for continuous casting cooling water in converter steelmaking process was studied, and a filter device whose filter element is porous PVC ceramic composite pipe was successfully developed. Sludge which was obtained by the porous PVC ceramic composite pipe filter was detected, and it was found that the porous PVC ceramic composite pipe filter had a good separation function. Water quality was detected before and after filtration, and it was found that turbidity and suspended solids of water significantly reduced after filtration, and water quality has reached the requirements. Through industrial experiments and nearly three years of practical application, the best operating conditions and backwash conditions of the porous PVC ceramic composite pipe filter were obtained.
