滩田饱和卤水直接进罐精制盐的新工艺

New Technology of Pruducing Refined Salt by Adding Salt Field Saturated Brine into Evaporating Pot Directly

利用滩田饱和卤水直接进蒸发罐蒸发结晶制取氯化钠,在制盐过程中采取三次洗涤方法,除去钙镁离子,以获得纯度超过99.1%的氯化钠和浓度较高的制盐母液。

NaCl was produced by adding salt field saturated brine into evaporating pot to evaporate and crystallize. In this process, Ca^2＋ and Mg^2＋ was removed by washing three times, and the aim is to obtain NaCl that its pureness was more than 99.1% and mother liquor with the quite high concentration for producing salt.
