Description

technical field [0001] The invention relates to the technical fields of chemistry, thermal engineering and geothermal new energy, in particular to a corrosion and scaling experiment detection system and method in the heat exchange process of geothermal water. Background technique [0002] As a renewable and clean energy, geothermal resources are more and more popular due to their advantages such as wide distribution, low cost, direct utilization, and less environmental pollution. Underground salt water is highly corrosive to materials such as metal pipes and heat exchanger plates, which can easily cause safety problems such as pipe leakage or heat exchange plate perforation corrosion failure. The analysis of the corrosion and scaling degree of geothermal water on site will help To judge the operation status of geothermal projects and reduce unnecessary parking maintenance; [0003] At present, in the field of development and utilization of geothermal resources, the phenomen...
