Description

Technical Field

[0001] The present invention relates to the technical field of cooling tower monitoring, and in particular to a real-time monitoring method and system for concrete degradation based on a cooling tower of a thermal power plant. Background Art

[0002] At present, the cooling tower for the circulating water body of thermal power plants is a thin-shell structure, and the cooling tower wall is usually prefabricated with reinforced concrete. Since reinforced concrete is a multi-phase coexisting building material composed of coarse aggregate, sand and cementing materials, reinforced concrete is essentially a porous and heterogeneous material, and there are usually a number of non-continuous micro cracks, pores and bubbles inside it. Carbon dioxide and sulfate in water and air can easily enter the concrete through the pores and cause degradation reactions, which significantly reduces the durability of concrete.

[0003] Due to the special functions of cooling towers, which require ventilation and water vapor evaporation, the deterioration of concrete materials is further aggravated in the environment in which they are located, resulting in hidden dangers such as local deformation of the tower wall and overall tilt, which seriously affects the structural performance of the cooling tower and its overall service life. If the degree of concrete deterioration of the cooling tower is not discovered in time, it will endanger the normal operation of the thermal power plant and may even cause production accidents in severe cases. Summary of the invention
