    • PURPOSE: A method for preparing chlorine dioxide in high yield is accomplished by proper adjustment of the supply ratio of sodium chlorite and chlorine, by which hydrogen-ion concentration condition is optimized. The chlorine dioxide, when applied to cooling water, showed excellent bactericidal effect against Legionella pneumophila when applied to cooling water. In addition, chlorine dioxide has proven to be effective in eliminating alien algae in cultivating lava. CONSTITUTION: In the generation of chlorine dioxide using sodium chlorite and chlorine, by using a flowmeter and a chemical pump, Cl2 supply rate and NaClO2 supply rate are controlled to adjust pH in the range 1.9 to 2.0. For the smooth dissolving of chlorine gas into sodium chlorite solution, chlorine gas is supplied through glass wool(7), and a baffle(8) is installed to be perpendicular to a sodium chlorite/chlorine inlet. The baffle plays role in converting laminar flow to turbulent flow within short time.
    • 目的:通过适当调整亚氯酸钠和氯的供应比,通过优化氢离子浓度条件来实现高产量制备二氧化氯的方法。 当应用于冷却水时,二氧化氯在用于冷却水时对嗜肺军团病菌显示出极好的杀菌作用。 此外,二氧化氯已被证明有效地消除培养熔岩中的外来藻类。 构成:使用亚氯酸钠和氯生成二氧化氯,通过使用流量计和化学泵,控制Cl2供应速率和NaClO2供应速率,调节pH在1.9至2.0。 为了将氯气平滑溶解在亚氯酸钠溶液中,氯气通过玻璃棉(7)供应,挡板(8)安装成与亚氯酸钠/氯气入口垂直。 挡板在短时间内将层流转化为湍流的作用。
