Description

System and method for inhibiting operating corrosion of a condenser TECHNICAL FIELD

[0001] The present application relates to the field of condenser corrosion prevention, in particular to a system and method for inhibiting operating corrosion of a condenser. BACKGROUND

[0002] The carbon steel structure of a direct air-cooled condenser is in a high flow rate, low pH value and negative pressure wet steam environment, and is subjected to the combined action of mechanical and chemical factors to cause flow accelerated corrosion to occur, and the main reason for the corrosion is that the maximum average flow rate of the low pressure cylinder exhaust steam can reach 80 m / s, and turbulence occurs after the pipeline is turned and the diameter is changed, and the local flow rate will be higher, and the scouring effect of the primary condensate on the carbon steel surface is intensified. During the condensation process of the low pressure cylinder exhaust steam in the air-cooled island, ammonia and oxygen are redistributed in the vapor-liquid two-phase. According to Henry's law, most of the ammonia is distributed in the vapor phase and is difficult to dissolve in the liquid film, which causes the pH value of the condensate to be very low. At the same time, trace amounts of difficult-to-vaporize corrosive ions such as Cl - , SO4 2- , etc. in the steam will be concentrated in the condensate, and the pH value of the liquid phase will be further reduced, promoting the dissolution of the metal oxide film. Under negative pressure, the low pressure cylinder exhaust steam on the surface of the carbon steel is close to oxygen-free, and the water temperature is 50-70 DEG C, so it is difficult for the carbon steel surface to form a stable protective film, and the erosion resistance is poor.

[0003] Therefore, it is particularly important to inhibit the occurrence of corrosion. By simply changing the structure of the equipment, the sudden change of the flow condition is avoided as much as possible, or a material with strong corrosion resistance is used to fill the local surface treatment, and for the direct air-cooled unit that has been put into operation, these measures and means are obviously unrealistic.

[0004] Therefore, for the direct air-cooled unit that has been put into operation, from the chemical aspect, an oxidizing agent with a high liquid phase distribution coefficient is added to the exhaust steam of the air-cooled condenser, and the liquid film oxidation-reduction potential of the carbon steel surface is increased, so that a dense and stable protective oxide film is formed on the metal surface, so as to slow down the corrosion of the direct air-cooled condenser system.

[0005] In the prior art, a metering pump is used to deliver the medicament to the medicine preparation box, and the concentration of the prepared medicament fluctuates, is high or low, and the concentration of the prepared medicament is unstable and inaccurate.
