电解槽直流供电-中英对照
电解工艺所需的直流电源由现场交流电源通过变压器/整流器单元提供。连至三相电源的基础单元将产生6伏脉冲直流电输出。更加复杂的整流器单元能够生成12伏和24伏的脉冲直流电输出。
直流输出的脉冲导致直流电压出现“波动”。可以通过增加脉冲的数目来减小波动大小。为了达到电解槽满意的工作要求，直流电压波动（通过电压波动峰谷幅值进行测量）不应超过总电压的5%。此限制要求适用于所有可能的正常工作条件，包括停车和设备使用寿命结束的情况。
在实际操作中，整流器的要求更易于受到其它因素的影响，例如，交流系统中的谐波和允许整流变压器功率因数。
电解槽压降
供给分框架总管的盐水和碱液必须具有足够高的压力，以克服电解槽和进口/出口分框架总管的摩擦压力损失和静压力水头影响。在各种流体条件下，从入口到分框架总管、从分框架出口总管（电解槽供给界区）到出口的联合压力损失都不能超过以下数值。
盐水压力损失 - 0.60 bar
碱液压力损失 - 0.72 bar
2.7电解槽吹扫用气
对于吹扫电解槽的氢气总管而言，压缩氮气是必不可少的。氮气供给压力必须至少为0.5 bar g。
对于吹扫电解槽的氯气总管而言，压缩空气（不含油）或氮气是必不可少的。空气或氮气供给压力必须至少为0.5 bar g。
如果在氯气系统吹扫工作中使用氮气，则必须将其与氢气系统吹扫所使用的氮气分离开来，这样氢气和氯气将不会通过氮气吹扫系统发生混合。

DC power supply for electrolytic cell
Electrolytic process for DC power supply provides the site AC power through the transformer/rectifier unit. Even to the basis of three-phase power supply unit will have a 6 volt dc pulse output. More sophisticated rectifier unit can generate the pulse dc 12 v and 24 v output.
Dc output pulse dc voltage will appear "volatility". It is applicable to increase the size to reduce the number of pulse wave. In order to meet the requirements of electrolyzer satisfied work, the dc voltage fluctuation (through the voltage fluctuation in peak amplitude measurement) should not exceed 5% of the total voltage. These restriction requirements apply to all possible normal working conditions, including parking and equipment service life of the end of the situation.
In practice, the requirement of the rectifier are more easily affected by other factors, for example, in the ac system harmonic and allow the power factor rectifier transformer.
The pressure drop of the electrolytic cell
Supply framework manager of saline and alkaline solutions must have a high enough pressure, in order to overcome the electrolyzer and import/export framework of main friction pressure loss and static pressure head. Under the condition of all kinds of fluid, from the entrance to the main framework, from export main framework supply battery (cell) to the export of pressure loss are no more than the following values.
Salt water pressure loss - 0.60 bar
Lye pressure loss - 0.72 bar
Cell purging gas
For purging electrolytic tank of hydrogen manifold, compressed nitrogen is essential. Nitrogen supply pressure must be at least 0.5 bar g.
For purging chlorine director general of the electrolytic cell, compressed air (oil) or nitrogen is essential. Air or nitrogen supply pressure must be at least 0.5 bar g.
If in chlorine system used in the nitrogen purging work, it must be with the hydrogen system used by purging nitrogen separation, such hydrogen and chlorine gas mixture will not occur through the nitrogen purging system.
