Description
技术领域technical field

背景技术Background technique
化学法二氧化氯发生器的工作原理是将氯酸钠与盐酸溶液混合生产二氧化氯和氯气的混合气体，目前，常用的反应器多为一级全混合式反应器，另外，在二氧化氯的制备中，其化学反应是吸热反应，现有的二氧化氯发生器的在反应的中后期经常会出现温度下降，导致原料转化率降低，二氧化氯的生成量减少。虽然有些发生器已经加入了加热装置，但是，无法做到实时检测，根据需要进行加热以提高原料转化率的目的，因此，现有的二氧化氯发生器的反应效率较低，亟需改进，提高原料转化率。另外，现有的二氧化氯发生器在使用一段时间后，容易被腐蚀，使用寿命一般都比较短，增加了使用成本。The working principle of the chemical method chlorine dioxide generator is to mix sodium chlorate and hydrochloric acid solution to produce a mixed gas of chlorine dioxide and chlorine gas. At present, the commonly used reactors are mostly one-stage fully mixed reactors. In the preparation of chlorine, the chemical reaction is an endothermic reaction, and the temperature of the existing chlorine dioxide generator often drops in the middle and late stages of the reaction, resulting in a decrease in the conversion rate of raw materials and a decrease in the amount of chlorine dioxide produced. Although some generators have added heating devices, real-time detection cannot be achieved, and heating is performed as required to improve the conversion rate of raw materials. Therefore, the reaction efficiency of existing chlorine dioxide generators is low and needs to be improved urgently. Improve the conversion rate of raw materials. In addition, the existing chlorine dioxide generators are easily corroded after being used for a period of time, and the service life is generally relatively short, which increases the cost of use.
