流程图
石灰石（石灰）——石膏湿法脱硫适用于大、 中型工业炉窑高、中硫煤机组烟气脱硫，已成功应用于国内和国际水泥、冶金、电力等工业工程中。
产品特点
●采用基于 CFD 分析的均流提效构件，提高脱硫效率
Adopt uniform-fluid device based on CFD analysis, increasing the desulfurization efficiency.
●严格按照 CFD 分析结果配置进口导流、托盘装置及节能环等结构，充分保证了烟气在塔体内的均匀分布，增
加了传质效率。
Equipped with inlet guiding device, tray device, energy saving ring and other structure in strict accordance
with CFD analysis, ensuring uniform distribution of flue gas in the tower and increasing the mass transfer
efficiency.
●合理布置喷淋层及喷头，采用高性能双头喷嘴，强化传质效果
Reasonable layout of spraying layer and nozzle, high-performance double nozzles, strengthening mass
transfer effect.
●采用专有程序设计各喷淋层以及各层的喷头，确保塔体内的喷淋覆盖率和均匀性，提高脱硫效率并节省浆液
循环量。
Adopt special program to design every spraying layer and its nozzles, ensuring high spraying coverage rate
and uniformity, which increases desulfurization efficiency and reduces circle quantity of slurry.
●采用高性能双头喷嘴，明显获得密集的二次雾化效果，增大浆液与烟气的接触面积；该喷头具有优良的耐磨
耐腐防堵功能，可靠性高。
Adopt high-performance double nozzles and achieve intensive secondary atomization, which enlarges the
area between gas and slurry liquid. This nozzle has excellent wear & corrosion resistance, anti-blocking
function and high reliability.
●采用高性能除雾器
Adopt high-performance demister
●采用多层高性能屋脊式除雾器，结合均流板技术，压力降低，临界分离粒径小，确保液滴携带量不大于
20mg/Nm3，最大限度减少雾滴携带粉尘量，实现超净排放。
Adopt multi-layer high-performance roof-type demister combined with flow equalization board technology
to achieve low pressure and small critical separated droplet diameter, ensuring escaping quantity of
droplet no more than 20mg/Nm3. It can minimize dust quantity carried by mist and achieve super-clean
emission.
● DCS 智能控制系统
DCS intelligent control system
DCS 全智能控制系统：
滤饼浓度控制，基于差压的除雾器自动冲洗控制等大大减低了能耗，确保排放达标。 增压风机入口压力控制回路，石灰浆供浆调节控制 SO2 出口浓度控制回路，真空脱水剂
DCS intelligent control system: adds inlet pressure control loop of fan; regulate the SO2 outlet concentration by slurry offering; concentration control by vacuum dehydrating agent filter cake; automatic washing control of demister based on differential pressure. All the controls reduce energy consumption and ensure that emission standard is achieved.
