Study of Manufacturing High Pure Chlorine Dioxide with Multi-Stage Compound Chlorine Dioxide Generator

Abstract:

Based on the status that conversion rate of Single-stage compound chlorine dioxide generator is not high in the market，we designed a multi-stage compound chlorine dioxide generator and discussed the best reaction conditions. At the same time ,we also focused on the reaction temperature, reactor pressure, concentration of raw materials and raw materials ratio on the performance of generator. The results show that the best reaction conditions of water bath temperature was 70°C、gas pressure was 60 ml • min^-1、mass fraction of HCl was 24%、mass fraction of NaClO₃ was 26%、Molar ratio of HCl and NaClO ₃was 3. Under these conditions, the Index ,such as production of ClO₂、production of effective chlorine、yield and purity of ClO₂、consumption rate of NaClO₃ and the ratio of ClO₂/Cl₂,reached a higher level, providing the technical basis for the mass production of Multi-stage compound chlorine dioxide generator.
