Abstract

The present invention relates to a method and apparatus for preparing chlorine dioxide useful in water purification plants, more specifically to a method and apparatus wherein the reactants can be evenly mixed, and side reactions can be inhibited, and which highly pure chlorine dioxide can be successively produced by automatically supplying a chlorite solution in an amount proportional to the current velocity of dilution water before the chlorite solution reaches an ejector nozzle. According to the present invention, it is possible to prepare highly pure chlorine dioxide more easily and economically compared to the conventional process and apparatus for preparing chlorine dioxide, and in addition, it is possible to easily control the concentration of chlorine dioxide and the production ratio of chlorine dioxide and chlorine at a desired proportion upon concurrent water-treatment with chlorine so as to maximize the pre-treatment effect of the water from water supply source.

　

WO2004002883   为水纯化厂生产二氧化氯的方法和装置

摘要：现发明是有关水纯化厂制备有水二氧化氯的方法和装置，尤为特别之处是该方法和装置，反应剂甚至能混合，副反应被抑制，亚氯酸溶液到达喷射嘴之前按比例按量对稀水流速，自动供亚氯酸水溶液，连续生产高纯二氧化氯。依现发明，更容易制高纯二氧化氯，比传统制备二氧化氯更经济，另外更容易控制二氧化氯浓度，生产二氧化氯和氯的比例是企望的比例，以企与氯共同同时处理水，以便对水源水取得最佳  处理效果。
