弱酸性H离子交换器在H-Na离子交换系统中的运行终点控制

Running Destination Control of the Weak-acid H Ion Exchanger in H-Na Ion Exchange System

分析了弱酸性H离子交换器中的离子分布状况,指出弱酸性H离子交换器在软化降碱系统与除盐系统中运行终点的差别,认为弱酸性H离子交换器在软化降碱系统应采用不足量酸再生,运行中出水应保持一定碱度,方可保证锅水水质指标符合国家标准,并计算出了弱酸性H离子交换器运行终点的控制指标。

Analyzes the ion distribution condition in the weak - acid H ion exchanger, and points out the differences of the running destination in the weak - acid H ion exchanger between the low alkaline soften system and the demineralixation system. Reckoned that the use of weak - acid H ion exchanger should be confined to less recycle acid and the water produced should maintain proper alkailinity so that the quality of the water in the bider can meet the national sandard. Also it calculates the control standard of running destination in the weak acidity H ion exchanger.
