众所周知，二氧化氯是一种无毒无害的氧化剂和消毒剂，对细菌、病毒及真菌孢子的杀灭能力均很强。二氧化氯一般是采用盐酸与氯酸钠(或亚氯酸钠)定量注入到反应罐内，反应罐在加热的情况下发生化学反应生成二氧化氯与氯气。一定浓度的氯酸钠水溶液(或者一定浓度的亚氯酸钠水溶液)和一定浓度的盐酸被定量输送到反应罐内，在一定温度下经过曝气反应生成二氧化氯和氯气的气液混合物，制成一定浓度的二氧化氯混合消毒液，再通过水射器吸入投加到消毒水体中或投加到需要消毒的物体中，完成二氧化氯和氯气的协同消毒、氧化等作用。As we all know, chlorine dioxide is a non-toxic and harmless oxidant and disinfectant, which has a strong ability to kill bacteria, viruses and fungal spores. Chlorine dioxide is generally injected quantitatively into the reaction tank by using hydrochloric acid and sodium chlorate (or sodium chlorite), and the reaction tank undergoes a chemical reaction under heating to generate chlorine dioxide and chlorine gas. A certain concentration of sodium chlorate aqueous solution (or a certain concentration of sodium chlorite aqueous solution) and a certain concentration of hydrochloric acid are quantitatively transported into the reaction tank, and a gas-liquid mixture of chlorine dioxide and chlorine gas is generated after aeration reaction at a certain temperature.

Alkali pump 28 inhales lye from the bottom of lye storage tank 29 and pumps it to the liquid distributor at the top of the alkali washing tower 3, and then flows down to the bottom of the alkali washing tower 3 through the packing inside the alkali washing tower 3 to complete the process of distributing the liquid from the top of the absorption tower 2. gas absorption. So far, the two-stage absorption of chlorine dioxide gas by the absorption tower and the treatment of the tail gas by the alkali washing tower 3 have been completed.
各吸收塔(包括碱洗塔)运行时，水由进水管22经布液器40流入塔体38内，经填料层37流向塔体38底部，液面逐步上升，浸没布气器，至排液口34位置处，经排液管流向储液罐11中(上述过程就是产生消毒液的过程)。二氧化氯气体经进气管42由布气器33进入水中，与水混合搅动，通过气液格栅5流向填料层6。气体与液体搅动混合后生成二氧化氯溶液，二氧化氯溶液由排液口3排出，多余气体上升通过气液格栅5和填料层6与下行的水混合，然后再由出气口10排出，进入下一吸收塔。液位开关35为常开式，当塔体38内液体出口流量小于进口流量的液面会漫过出液口34，逐步上升触发液位开关35，此时液位开关35闭合，发出信号，停止进水，可保证吸收塔的安全。当塔体38内压力高出设定值时安全阀39开启释放塔内压力，确保吸收塔安全运行。When each absorption tower (including the alkali washing tower) is in operation, water flows into the tower body 38 from the water inlet pipe 22 through the liquid distributor 40, flows to the bottom of the tower body 38 through the packing layer 37, and the liquid level rises gradually, submerging the gas distributor, to the exhaust At the position of the liquid port 34, it flows into the liquid storage tank 11 through the drain pipe (the above-mentioned process is exactly the process of producing disinfectant). Chlorine dioxide gas enters the water from the air distributor 33 through the air inlet pipe 42, mixes and stirs with the water, and flows to the packing layer 6 through the gas-liquid grid 5. The gas and the liquid are stirred and mixed to form a chlorine dioxide solution, which is discharged from the liquid discharge port 3, and the excess gas rises through the gas-liquid grid 5 and the packing layer 6 to mix with the descending water, and then is discharged from the gas outlet 10. into the next absorption tower. The liquid level switch 35 is a normally open type. When the liquid outlet flow in the tower body 38 is less than the liquid level at the inlet flow, the liquid level will overflow the liquid outlet 34 and gradually rise to trigger the liquid level switch 35. At this time, the liquid level switch 35 is closed and a signal is sent. Stopping water intake can ensure the safety of the absorption tower. When the pressure in the tower body 38 is higher than the set value, the safety valve 39 is opened to release the pressure in the tower to ensure the safe operation of the absorption tower.
来自两级吸收塔的液体分别通过第一排液管24和第二排液管25汇入储液罐11中，经过与储液罐11连接的消毒液管21输送至消毒场所。可打开取样阀19取样检测。The liquid from the two-stage absorption towers flows into the liquid storage tank 11 through the first liquid discharge pipe 24 and the second liquid discharge pipe 25 respectively, and is transported to the disinfection place through the disinfectant liquid pipe 21 connected with the liquid storage tank 11 . The sampling valve 19 can be opened for sampling and testing.
