摘要
改进了亚硫酸氢钠溶液的生产方法,气体系统增用预洗塔,生产出了具有纯度高、无机械杂质优点的亚硫酸氢钠。吸收系统中采用一级吸收塔并联的方式,两个一级吸收塔交替使用,重复作业,保证了生产的连续进行。
Improved the production methods of sodium bisulfite solution,gas system with prewash tower,produced has advantages of high purity,no mechanical impurities of sodium bisulfite.Absorption system with the method of level of absorption tower in parallel,two level of absorber used interchangeably,repeated operation,to ensure the continuous production.
