湿法烟气脱硫技术：优点：湿法烟气脱硫技术为气液反应，反应速度快，脱硫效率高，技术成熟，适用面广。缺点：生成物是液体或淤渣，较难处理，设备腐蚀性严重；洗涤后烟气需再热，能耗高；占地面积大，投资和运行费用高；系统复杂、设备庞大、耗水量大、一次性投资高，一般适用于大型电厂。常用的湿法烟气脱硫技术有石灰石-石膏法、间接的石灰石-石膏法、柠檬吸收法等。干法烟气脱硫技术：优点：干法烟气脱硫技术为气同反应，相对于湿法脱硫系统来说，设备简单，占地面积小、投资和运行费用较低、操作方便、能耗低、生成物便于处置、无污水处理系统等。缺点：反应速度慢，脱硫率低，先进的可达60-80%。此外，吸收剂利用率低，磨损、结垢现象比较严重，在设备维护方面难度较大，设备运行的稳定性、可靠性不高。分类：常用的干法烟气脱硫技术有**碳吸附法、电子束辐射法、荷电干式吸收剂喷射法、金属氧化物脱硫法等。
Wet flue gas desulfurization technology: advantages: wet flue gas desulfurization technology is gas-liquid reaction, fast reaction speed, high desulfurization efficiency, mature technology and wide application. Disadvantages: the product is liquid or sludge, which is difficult to deal with and the equipment is seriously corrosive; The flue gas after washing needs to be reheated, with high energy consumption; Large floor area and high investment and operation costs; With complex system, huge equipment, large water consumption and high one-time investment, it is generally suitable for large power plants. Common wet flue gas desulfurization technologies include limestone gypsum method, indirect limestone gypsum method, lemon absorption method, etc. Dry flue gas desulfurization technology: advantages: dry flue gas desulfurization technology is the same reaction of gas. Compared with wet desulfurization system, dry flue gas desulfurization technology has the advantages of simple equipment, small floor area, low investment and operation cost, convenient operation, low energy consumption, easy disposal of products, no sewage treatment system, etc. Disadvantages: slow reaction speed, low desulfurization rate, advanced up to 60-80%. In addition, the utilization rate of absorbent is low, the phenomenon of wear and scaling is serious, it is difficult to maintain the equipment, and the stability and reliability of equipment operation are not high. Classification: common dry flue gas desulfurization technologies include * * carbon adsorption method, electron beam radiation method, charged dry absorbent injection method, metal oxide desulfurization method, etc.
