水质分析仪表在pH加药控制上的应用

Issuing time:2018-11-16 09:26

酸碱pH调节加药装胃在各种I业环境的水处理都有着广泛的应用,在任何水溶液中,氢离子和氢氧根离子都是一固定数值,称为水的离子积常数。调节PH值就是靠调节水中两种离子的含显来达到最终改变水质的目的。酸碱PH调节加药装置应用场合:电镀废水,颜料的生产,印染厂水处理,冷却水,化工工艺(反应釜)等,


     酸碱PH调节加药装置系统是通过pH在线控制器自动检测被测液体的PH值,并通过设定控制范围转换成电流信号输出到自动加药计泵,自助加药计泵(设定接收信号范围及输出频率范围)通过接收到的信号,自动调节计星泵的加药量。酸碱pH调节加药装置组成:


     酸喊pH调节加约装置否止常稳定运行,关键取决于PH控制器,加药泵。加药泵的选型根据流体介质选型很重要,尤其是pH自动调节系统经常佘用到浓酸及浓碱,能否在关键需要加药的时候精确的投加所需要的剂量是很重要的。
