【摘要】：通过电解参数对发生器运行效果影响试验,采用单因素方差分析方法,研究了盐水pH值、盐水浓度、电流密度、盐水流量等电解参数对发生器运行效果指标有效氯浓度、交流电耗、盐耗和运行成本的影响。结果表明:盐水pH值对发生器运行效果有显著性影响,盐水为中性时发生器运行效果最好;盐水浓度、电流密度与盐水流量对发生器运行成本均无显著影响,但对有效氯浓度均有显著性影响;盐水浓度、电流密度增加,有效氯浓度提高;盐水流量增加,有效氯浓度降低;设备Tjb-7.5的最佳工况为:盐水流量6L/h,电流密度为18A/dm2,盐水浓度为30g/L,此时设备有效氯浓度7.01g/L,运行成本最低9.52元/kg。
[Abstract]:The effect of electrolytic parameters on the operating effect of the generator was studied by using single factor variance analysis method. The effective chlorine concentration was studied by electrolytic parameters such as pH value of brine, concentration of brine, current density and flow rate of brine. The results show that the pH value of brine has a significant effect on the operation effect of the generator, and when the brine is neutral, the generator has the best operation effect, the concentration of brine, the concentration of brine, and the pH value of brine have a significant effect on the operation effect of the generator. The current density and brine flow rate had no significant effect on the operating cost of the generator, but they had a significant effect on the effective chlorine concentration, the salt water concentration, the current density and the available chlorine concentration increased, the salt water flow rate increased, the effective chlorine concentration decreased. The optimal operating conditions of the equipment Tjb-7.5 are as follows: brine flow rate 6L / h, current density 18A / dm2, brine concentration 30g / L, and the equipment effective chlorine concentration 7.01g / L, the lowest operating cost is 9.52 yuan / kg / kg.
