循环水阻垢剂自动配药和投加技术的工程应用

Engineering Application of Automatic Dispensing and Dosing Technology for Circulating Water Scale Inhibitor

循环水阻垢剂在循环水处理中起着至关重要的作用,其投加方式和技术监督直接关系到对换热设备的缓蚀阻垢性能,这也是全国各企业在环保零排放的驱动下出现循坏水冷却设备发生结垢和腐蚀后最易忽略的一个因素。根据工程实际,对循环水阻垢剂的配置和投加方式进行研究和改造,在某电厂率先实现循环水阻垢剂的自动配置和投加。阻垢剂供货质量得到有效的监督,配置浓度稳定可控,投加计量自动、定量且可控。循环水在原有指标控制策略下,换热设备结垢腐蚀情况明显减缓。循环水阻垢剂的自动配药和投加在工程实际应用中效果良好,具有很好的应用推广价值,同时具有很好的经济效益和环境效益,可为相关工程的设计和改造提供借鉴。

Circulating water scale inhibitor plays an important role in circulating water treatment,and its dosing mode and technical supervision are directly related to the corrosion and scale inhibition performance in heat exchange equipment.This is also one of the most easily neglected factors after scaling and corrosion of circulating water cooling equipment in enterprises across the country.According to real status of the project,research and transformation are carried out on dispensing and dosing mode of scale inhibitor for circulating water.In a certain power plant,automatic dispensing and dosing of scale inhibitor for circulating water are realized first.The supply quality of scale inhibitor can be effectively supervised,dispensing concentration is stable and controllable,and dosing measurement is automatic,quantitative and controllable.Under original index control strategy of circulating water,the scaling and corrosion of heat exchange equipment are significantly reduced.The automatic dispensing and dosing of scale inhibitor for circulating water have good effect in the practical application of the project,with good application and promotion value,as well as good economic and environmental benefits,which can be used for reference in the design and transformation of relevant projects.
