锅炉给水,必须通过处理,降低硬度,达到锅炉给水标准,防止炉内结垢,以保证锅炉安全,经济运行。 工业生产,通常采用离子交换法工艺降低给水硬度。 离子交换系统运行一定的时间后,由于水中的Fe~(3+)等过渡金属离子不易被盐再生,使树脂逐步失去交换能力,累积形成中毒现象。为了使中毒的树脂复活,通过酸处理辅以 Boiler feed water must be treated to reduce the hardness, to meet the boiler feed water standards to prevent scale fouling in order to ensure the boiler safe and economical operation. Industrial production, usually using ion exchange process to reduce water hardness. Ion exchange system running for a certain period of time, due to water Fe ~ (3 +) and other transition metal ions are not easy salt regeneration, the resin gradually lost the ability to exchange, the cumulative formation of poisoning. In order to revive the poisoned resin, supplemented by acid treatment
