摘要:

针对纺织厂空调循环水系统结垢严重的问题,基于磁阻垢技术和投加阻垢剂,通过垢样分析发现磁化处理是通过改变晶型让形成的钙垢沉积性能下降,而阻垢剂是通过破坏晶体生长来抑制钙垢量;通过静态实验发现,这两种方法对于循环时间较短浓缩倍数较低的水样抑垢效果较好,在PC2566型、YC2655型、YL505型聚羧酸类阻垢剂中,YC2655型阻垢剂抑垢效果最佳,对于已经循环一个月的循环水,磁阻垢比投加聚羧酸类阻垢剂抑垢率更高,其抑垢率高达96%;由于电导率和pH能够反应结垢倾向,电导率和pH越小,水样结垢倾向也就越小,因此通过检测对比分析未经处理的水样以及经两种方法处理后水样的电导率、pH随时间变化的规律,发现磁化处理比投加阻垢剂处理的抑垢效果更好且更稳定。最终得出磁化处理比投加聚羧酸类阻垢剂能更好地解决纺织厂空调循环水系统结垢问题。

Abstract:

In view of the serious scaling in the air-conditioning circulating water system of textile mills, based on magnetic scale inhibition technology and dosing scale inhibitors, through analyzing scale samples, this paper finds that magnetization treatment can reduce deposition of calcium scale that has been formed by changing the crystal form, while the scale inhibitor inhibits the amount of calcium scale by destroying the growth of crystals. Through static experiments, it is found that these two methods have a better inhibiting effect on water samples with shorter circulation time and lower concentration ratio. YC2655 scale inhibitor has the best inhibiting effect among PC2566, YC2655 and YL505 polycarboxylic acid scale inhibitors. For circulating water that has been circulated for 1 month, magnetic scale inhibitor has a higher anti-scaling rate than dosing polycarboxylic acid scale inhibitor, and its anti-scaling rate is up to 96%. Electrical conductivity and pH can reflect scaling tendency, the smaller electrical conductivity and pH, the smaller scaling tendency of water samples. Therefore, through the detection and comparison of untreated water samples and water samples treated with the above two methods, by analyzing the change rules of their conductivity and pH over time, it is found that the magnetization treatment has a better and more stable anti-scaling effect than dosing scale inhibitor. Finally, it is concluded that compared with dosing polycarboxylic acid scale inhibitor, magnetic scale inhibitor can better solve the scaling of the air-conditioning circulating water system of textile mills.
