摘　　要：从水电解槽电解电流异常的表象着手,由表及里,深入分析了引起水电解槽电解电流异常的主要原因,然后根据水电解槽冷却水的酸碱度为强碱性的现象,确定了由于水电解槽换热器管程(碱液通道)破裂,导致管程和壳程(冷却水的通道)相通,从而使冷却水和碱液混合在一起,以致冷却水的碱性提高了.由于碱液泄漏,使得电解液的浓度下降,从而导致电解液的导电能力下降,电解槽的电解电流也下降.From the abnormal electrolysis current of electrolysing cell of water, from outward appearance to inner essence, this article analyzes the main reasons deeply, which results in abnormal electrolysis current. According to the phenomenon that cooling water of eleetrolysing cell of water is strong alkaline, we can draw a conclusion because the heat exchanger tubes passes, passes of lye of electrolysing cell of water, crack, the tube passes and shell passes, passes of cooling water of water electrolysing cell of water, inter- link and the cooling water blends in lye, which results in the alkalescency of cooling water arise. Because the lye leaks, electrolyte concentration drops, electrolyte conductivity and current of electrolysing cell of water reduce.
