烧碱是高耗能产品,降低烧碱能耗,特别是电耗对降低成本、提高能源利用率和产品竞争力至关重要,隔膜法烧碱推广使用扩张阳极、活性阴极、改性膜等技术是降低能耗的有效措施。南京化工厂推广使用活性阴极、改性膜技术对电解槽进行改造,平均降低槽电压0.186伏,平均节电6%,一年收回投资,效益十分显著,此项目获得江苏省节能示范工程项目。
Caustic soda is a high energy-consuming product, reducing the energy consumption of caustic soda, in particular, power consumption to reduce costs and improve energy efficiency and product competitiveness is crucial, the promotion of diaphragm caustic soda expansion cathode, active cathode, modified membrane technology is to reduce Energy-efficient measures. Nanjing Chemical Plant to promote the use of active cathode, modified membrane technology to transform the electrolyzer to reduce tank voltage on average 0.186 volts, an average of 6% saving, one year to recover the investment, the effect is very significant, this project has been energy-saving demonstration projects in Jiangsu Province.
