Description

Technical Field

[0001] The present invention relates to the technical field of condenser anti-corrosion, and in particular to a system and method for inhibiting condenser operation corrosion. Background Art

[0002] The carbon steel structure of the direct air-cooled condenser is in a wet steam environment with high flow rate, low pH value and negative pressure. The combined effect of mechanical and chemical factors causes flow-accelerated corrosion. The main reasons for the corrosion are: the maximum average flow rate of the low-pressure cylinder exhaust steam can reach 80m / s. Due to the turbulence caused by the pipe bending and diameter change, the local flow rate will be higher, which aggravates the scouring effect of the primary condensate on the carbon steel surface. During the condensation process of the low-pressure cylinder exhaust steam in the air-cooled island, ammonia and oxygen will be redistributed between the vapor and liquid phases. According to Henry's law, most of the ammonia is distributed in the vapor phase and is difficult to dissolve in the liquid film, resulting in a very low pH value of the condensate. At the same time, trace amounts of non-volatile corrosive ions such as Cl in the steam - 、SO 4 2- The condensate will be concentrated in the condensate, and the pH value of the liquid phase will be further reduced, which will promote the dissolution of the metal oxide film. Under negative pressure, the primary condensate of low-pressure cylinder exhaust steam on the carbon steel surface is almost oxygen-free. In addition, the water temperature is between 50 and 70°C, so it is difficult to form a stable protective film on the carbon steel surface, and the erosion resistance is poor.

[0003] How to inhibit the occurrence of corrosion is particularly important. Simply changing the structure of the equipment to avoid sudden changes in flow conditions, or using materials with strong corrosion resistance to fill in local surface treatment, is obviously unrealistic for the direct air-cooled units that have been put into operation.

[0004] Therefore, for the direct air-cooled units that have been put into operation, from a chemical point of view, an oxidant with a high liquid phase distribution coefficient is added to the exhaust steam of the air-cooled condenser to try to increase the redox potential of the liquid film on the carbon steel surface, so that a dense and stable protective oxide film is formed on the metal surface, thereby achieving the purpose of slowing down the corrosion of the direct air-cooled condenser system.
