The energy conservation and consumption reduction of diaphragm electrolyzer with metal anodes is a complex and systematic work and one of the most important factors influecing the production cost of diaphragm caustic soda.The following measures are put forward:in respect of technology,adopting Gore film filter to improve the quality of refined brine,adopting modified diaphragm and expanded anode technology to improve the process of diaphragm manufacture;in respect of management,clearly defining responsibilities,enforcing assessment rules,programming,standardizing and systematizing the management of electrolyzers,improving the qualities of workers,adopting microcomputers to help the management of electrolyzers.These modifications bring about remarkable results in respect of energy conservation and consumption reduction,the average cell voltage reduces from 3.270 V to 3.162 V and the average electric energy consumption reduces from 2 440 kW·h/(t·100% NaOH) to 2 376 kW·h/(t·100% NaOH) at 1.7 kA/m2 of current density.
