壓(ya)力式(shi)鹽(yan)(yan)溶(rong)解器(qi)是(shi)制(zhi)備鈉離(li)子交換器(qi)還原(yuan)需用鹽(yan)(yan)溶(rong)液或鹽(yan)(yan)溶(rong)液過濾用的(de)。在壓(ya)力式(shi)鹽(yan)(yan)溶(rong)解器(qi)的(de)底部(bu)設(she)有排水(shui)(shui)盤和石英砂(sha)過濾層。制(zhi)備鹽(yan)(yan)溶(rong)液時，先(xian)將(jiang)一定數量(liang)的(de)鹽(yan)(yan)裝入壓(ya)力式(shi)鹽(yan)(yan)溶(rong)解器(qi)內，用具有壓(ya)力的(de)水(shui)(shui)通過食鹽(yan)(yan)層將(jiang)鹽(yan)(yan)溶(rong)解并經石英砂(sha)過濾層過濾。經過過濾的(de)清鹽(yan)(yan)水(shui)(shui)從壓(ya)力式(shi)鹽(yan)(yan)溶(rong)解器(qi)下部(bu)出水(shui)(shui)管引出。壓(ya)力式(shi)鹽(yan)(yan)溶(rong)解器(qi)運行一段時間后應進
