In order to effectively utilize the space in the electrolyzer, the size of electrolyzer depends primarily on the size of specified current potential water generating capacity, battery lead plate, the Several Factors such as sheet number of the interior battery lead plate of installing of groove.Wherein total battery lead plate area and specified current potential water generating capacity have direct relation, and the long-width ratio of the sheet number of battery lead plate and every plate electrode plate is also closely related with electrolytic efficiency.Particularly the length of battery lead plate determines the time length that current are walked in electrolyzer, has determined the electrolysis time of water in electrolyzer.But contriver's research learns that the length of battery lead plate is not that the longer the better.Experiment through repeatedly shows, under the identical prerequisite of pole plate area, and length bigger (width is more little), the effect of brine electrolysis is relatively poor on the contrary.Electrochemical reaction with following formula (1)～(10) is taking place because in electrolytic process in simultaneously on plate.The reaction of formula (1)～formula (7) is mainly taking place on the anode generally speaking.According to the difference of pole plate coated material composition, reaction lays particular emphasis on formula (1)～formula (5), or formula (6)～formula (7).Active oxygen (O) or reactive chlorine (HClO) that both of these case produces down all are strong oxydised components, can produce good sterilization effect.
But if pole plate is long, the time that current are walked in electrolyzer is long, then possibly produce the chemical reaction suc as formula (8)～formula (10), and the oxidisability of the ClO-that produces is far below the oxidation capacity of HClO.In addition, the HClO of generation
2And HClO
3Though also be strong oxidizer, oxidation capacity also is lower than HClO.Therefore, tap water is walked overlong time in electrolyzer, possibly cause the activity of brine electrolysis to reduce, thereby reduce sterilization effect.
