Example Embodiment
[0033] Embodiment 1 of the present invention: A method for fine treatment of condensed water in nuclear power plants, which adjusts the flow of condensate to be deeply treated through the pre-filter, cation exchanger, and resin trap by controlling the opening and closing states of valves in the pipeline. , The sequence of the anion and cation exchanger and the resin trap B is to meet the advanced treatment requirements for condensate under different operating conditions. In addition to ionic impurities, the condensate to be further treated also contains metal corrosion products and suspended impurities. Among them, the metal corrosion products are mainly iron oxides. When the iron content of the metal corrosion products in the condensate to be further treated is greater than 1000μg / At L, the purification of condensed water includes the following steps:
[0034] Step a: Open valve one 8, valve two 9 and valve six 13, close valve five 12, valve three 10, and valve four 11. The con...
