为了防止冷却器水管出现结垢或腐蚀问题,目前所采用的均为化学处理方法,这会造成二次污染或花费大量资金,因此采用物理方法———磁处理方法对循环冷却水测定不同磁场强度下循环水的pH值、电导率、PSI的变化情况。对比未经过磁处理的循环水,试验结果表明防垢效果最佳时的磁场强度为34 000 Gs,可以有效降低pH值,使旧垢脱落,减少循环水结垢的可能性,并用首钢高炉冷却水进行磁处理,取得了满意的效果。 In order to prevent the occurrence of scaling or corrosion of the cooler pipes, the current are used in chemical treatment methods, which will cause secondary pollution or spend a lot of money, so the use of physical methods --- magnetic treatment of circulating cooling water determination of different magnetic fields Strength, circulating water pH, conductivity, PSI changes. Compared with the recycled water without magnetic treatment, the test results show that the magnetic field intensity with the best anti-scaling effect is 34 000 Gs, which can effectively lower the pH value, shed the old scale and reduce the possibility of circulating water scaling, Water magnetic treatment, and achieved satisfactory results.
