水質分析儀表在pH加藥控制上的應用

Issuing time:2018-11-16 09:26

酸堿pH調節加藥裝胃在各種I業環境的水處理都有著廣泛的應用,在任何水溶液中,氫離子和氫氧根離子都是一固定數值,稱為水的離子積常數。調節PH值就是靠調節水中兩種離子的含顯來達到最終改變水質的目的。酸堿PH調節加藥裝置應用場合:電鍍廢水,顏料的生產,印染廠水處理,冷卻水,化工工藝(反應釜)等,


     酸堿PH調節加藥裝置系統是通過pH在線控制器自動檢測被測液體的PH值,并通過設定控制范圍轉換成電流信號輸出到自動加藥計泵,自助加藥計泵(設定接收信號范圍及輸出頻率范圍)通過接收到的信號,自動調節計星泵的加藥量。酸堿pH調節加藥裝置組成:


     酸喊pH調節加約裝置否止常穩定運行,關鍵取決于PH控制器,加藥泵。加藥泵的選型根據流體介質選型很重要,尤其是pH自動調節系統經常佘用到濃酸及濃堿,能否在關鍵需要加藥的時候精確的投加所需要的劑量是很重要的。
