Diagnosis and analysis system and method for corrosion state of circulating cooling water

Abstract

The invention relates to a diagnosis and analysis system and method for the corrosion state of the circulating cooling water. The system comprises four kinds of acquisition modules of water quality, condenser tube attachments, pharmaceutical treatment formula information and equipment material and structural data, the above modules are respectively connected with a water quality analysis module, an attachment analysis module, a pharmaceutical treatment formula and equipment material analysis module and a structural analysis module and are then connected with a decision layer module through a data layer module and a feature layer data processing module. The method includes: acquiring water quality information, equipment material information, structural information, condenser attachment information and pharmaceutical treatment formula information; respectively analyzing and processing data acquired by the acquisition modules; excluding pathological data; extracting characteristic quantity of the analyzed data; conducting comprehensive analysis and diagnosis of an expert system. Corrosion and scaling conditions are integrated, scaling analysis and solution are given, feedwater qualityof boilers is guaranteed, and long-term, efficient and economical operation of the circulating cooling water system is ensured.

Description

technical field [0001] The invention belongs to the technical field of circulating cooling water treatment in thermal power plants, in particular to a system and method for diagnosing and analyzing the corrosion state of circulating cooling water. Background technique [0002] With the improvement of the level of thermal power plants, higher requirements are also put forward for their circulating cooling water systems. Improper treatment of circulating water will not only increase operating costs, but also lead to system scaling, corrosion and other risks, endangering the thermal system. safe operation. [0003] During the use of the circulating cooling water, due to the continuous evaporation and concentration of the water, the content of various organic matter, sediment, various salts and other impurities brought into the system with the supplementary water will gradually increase, coupled with the reproduction of bacteria and algae. , making the circulating water show st...
