摘要
针对来自山西省的2处地热水,应用Larson指数和Langelier饱和指数,对其腐蚀和结垢趋势进行分析判断,并提出langelier饱和指数新模型;在316不锈钢、紫铜和20#碳钢基底上进行地热水静态腐蚀结垢实验,并实验考察地热水浓缩一倍后的结垢状况。结果表明,2种地热水均属于强腐蚀型,地热水B比地热水A更易结垢;新模型可更准确判断地热水的结垢趋势。
Corrosion and fouling trends of two different types of geothermal water obtained from Shanxi province were analyzed using Larson and Langelier saturation indexes, and a new model of Langelier Saturation index was proposed. Static corrosion and fouling experiments on the samples of 316 stainless steel, red copper as well as carbon steel of No. 20 type in geothermal water were carried out. Crystallization fouling behaviors of the two types of geothermal water were compared by evaporating concentration of geothermal water to half original volume. The results indicate that both types of the geothermal water are highly corrosive and geothermal water B is easier to form crystallization fouling than A; the new model shows better agreement with the experimental results of fouling trends.
