工作时，多级湿式乳化脱硫塔喷淋装置的三层喷淋管4喷洒雾化乳化纯碱液，烟气经过风机6抽取到达进气口7，并经过冷却喷淋装置降温进行第一步脱硫反应后后进入塔体与乳化碱液反应；由于烟气流速大，塔体为气密性，烟气在风力集能气旋室8与乳化碱液高速旋切，使乳化碱液液滴进一步减小，增大了反应接触面积，提高了脱硫效率和碱液的利用率；烟气充分脱硫后到达双层除雾器3。过程中未反应完全的乳化碱液沉入集液室12，通过控制阀17与排放管引入pH调节池10，循环利用价格较高的纯碱钠离子，提高脱硫效率的同时有效降低了成本。脱硫剂为乳化碱液。pH调节池调节pH值为8-10。pH调节池中加入纯碱（碳酸钠）、烧碱（氢氧化钠）、水通过电动搅拌器20搅拌制成乳化碱液。When working, the three-layer spray pipe 4 of the spray device of the multi-stage wet emulsification desulfurization tower sprays the atomized emulsified soda ash solution, the flue gas is extracted by the fan 6 and reaches the air inlet 7, and is cooled by the cooling spray device for the first step of desulfurization After the reaction, it enters the tower body to react with the emulsified lye; because the flue gas flow rate is large, the tower body is airtight, and the flue gas is rotary-cut with the emulsified lye at a high speed in the wind power energy-collecting cyclone chamber 8, so that the emulsified lye droplets are further reduced. Small size, which increases the reaction contact area, improves the desulfurization efficiency and the utilization rate of lye; after the flue gas is fully desulfurized, it reaches the double-layer demister 3. During the process, the unreacted emulsified lye sinks into the liquid collection chamber 12, and is introduced into the pH adjustment tank 10 through the control valve 17 and the discharge pipe, so as to recycle the expensive sodium ions of soda ash, improve the desulfurization efficiency and effectively reduce the cost. Desulfurization agent is emulsified lye. The pH adjustment pool adjusts the pH value to 8-10. Soda ash (sodium carbonate), caustic soda (sodium hydroxide) and water are added into the pH adjustment tank and stirred by an electric mixer 20 to make emulsified lye.
