摘要
综合运用滤元离线清洗技术（OFECT）、“五要素”铺膜工艺、“八步法”爆膜工艺、“火电厂凝结水精处理混床运行性能诊断及优化专家系统”软件等多项专利或专有技术，对某电厂的凝结水精处理系统进行了运行优化，同时应用了的XTW-C型粉末树脂新产品。优化后，水汽品质明显改善，精处理出水Fe的质量浓度由18～25μg／L降至3μg／L，Cl^-的质量浓度由8～10μg/L降至1μg/L以下，主蒸汽Fe的质量浓度由10～15μg／L降至4μg／L，凝结水Fe的质量浓度由25～30μg／L降至10μg／L，保证了机组的安全运行。
The optimization on operation of condensate polishing system in one power plant was performed by a number of patents or proprietary technologies, such as the OFECT, five-factor precoating techniques, eight-step backwash techniques, software of＂Operational Performance Diagnosis and Optimization System for Condensate Polishing Mixed Bed in Thermal Power Plant＂ etc. Meanwhile, developed XTW-C powdered resin was used. After optimizing, the quality of water-steam cycle was improved obviously. The mass concentration of Fe in effluent of condensate polishing fell to 3 μg/L from 18-25 μg/L and the mass concentration of Cl^- was less than 1μg/L from 8 - 10 μg/L, the mass concentration of Fe fell to 4 μg/L from 10 - 15 μg/L in main steam and to 10 μg/L from 25-30 μg/L in condensate. The results assure the unit safe in operation.
