在“双碳”目标驱动下，脱硫技术作为工业环保的核心环节备受关注。然而，看似成熟的脱硫工艺背后，仍存在诸多技术瓶颈亟待突破。本文从一线实践出发，梳理当前脱硫领域的五大核心难点，揭开环保卫士们的“硬骨头”。

　　Driven by the "dual carbon" goal, desulfurization technology has attracted much attention as a core component of industrial environmental protection. However, behind the seemingly mature desulfurization process, there are still many technical bottlenecks that urgently need to be overcome. This article starts from frontline practice, sorts out the five core difficulties in the current desulfurization field, and reveals the "hard bones" of environmental defenders.

　　01设备腐蚀：隐形“杀手”缩短系统寿命脱硫系统长期接触酸性气体和化学药剂，管道、反应塔等关键设备易发生腐蚀漏液。尤其湿法脱硫中，pH值控制不当（如低于8.2时）会加速金属腐蚀，导致点蚀穿孔?17。部分国产成人综合亚洲AV麻豆下载显示，脱硫液中的硫酸钠副盐含量超标（超76g/L）时，结晶沉积进一步加剧腐蚀，维修成本可占年运营费用的15%以上。

　　01 Equipment Corrosion: Invisible "Killer" Shortens System Lifespan. The desulfurization system is exposed to acidic gases and chemical agents for a long time, and key equipment such as pipelines and reaction towers are prone to corrosion and leakage. Especially in wet desulfurization, improper pH control (such as below 8.2) can accelerate metal corrosion, leading to pitting and perforation. Some cases have shown that when the content of sodium sulfate by-product in desulfurization solution exceeds the standard (over 76g/L), crystal deposition further exacerbates corrosion, and maintenance costs can account for more than 15% of annual operating expenses.

　　02废水处理：高盐重金属成“烫手山芋”湿法脱硫虽效率高，但产生的废水pH值低（4-6）、含石膏颗粒及铅/汞等重金属，处理难度极大?6。传统中和沉淀法难以彻底去除溶解性污染物，而蒸发结晶工艺能耗又居高不下。更棘手的是，废水处理成本占脱硫总成本的20%-30%，成为企业环保合规的“拦路虎”?。

　　02 Wastewater treatment: Wet desulfurization with high salt and heavy metals to produce "hot potato" has high efficiency, but the resulting wastewater has a low pH value (4-6), contains gypsum particles and heavy metals such as lead/mercury, and is extremely difficult to treat. The traditional neutralization precipitation method is difficult to completely remove soluble pollutants, and the energy consumption of the evaporation crystallization process is also high. What's even more tricky is that the cost of wastewater treatment accounts for 20% -30% of the total cost of desulfurization, becoming a "roadblock" to corporate environmental compliance.

　　03副产物困局：资源化利用遇技术瓶颈脱硫过程中产生的硫酸钙（石膏）、硫氰化钠等副产物，若无法有效利用将造成二次污染。例如，湿法脱硫石膏纯度不足时难以建材化，堆存占地问题突出；而干法脱硫的硫酸钠副盐积累会反向腐蚀设备，形成恶性循环?57。据测算，仅副产物处置费用即可增加吨处理成本0.3-0.5元?。

　　03 byproduct dilemma: Resource utilization encounters technological bottlenecks. The by-products generated during the desulfurization process, such as calcium sulfate (gypsum) and sodium thiocyanate, if not effectively utilized, will cause secondary pollution. For example, when the purity of wet desulfurization gypsum is insufficient, it is difficult to convert it into building materials, and the problem of storage and land occupation is prominent; The accumulation of sodium sulfate by-product in dry desulfurization will reverse corrode the equipment, forming a vicious cycle. According to calculations, the cost of by-product disposal alone can increase the processing cost by 0.3-0.5 yuan per ton.

　　04技术路线选择：效率与成本的博弈?湿法脱硫?：石灰石-石膏法效率超95%，但系统复杂、耗水量大，且易产生“石膏雨”污染；?干法脱硫?：循环流化床工艺节水明显，但脱硫效率波动大（85-95%），钙硫比过高时经济性下降；?生物脱硫?：运行成本低至0.04元/m?，但对气体成分敏感，规模化应用仍待突破；

　　04 Technical route selection: The game between efficiency and cost Wet desulfurization: Limestone gypsum method has an efficiency of over 95%, but the system is complex, consumes a large amount of water, and is prone to "gypsum rain" pollution; Dry desulfurization: The circulating fluidized bed process saves water significantly, but the desulfurization efficiency fluctuates greatly (85-95%), and the economy decreases when the calcium sulfur ratio is too high; Biological desulfurization: The operating cost is as low as 0.04 yuan/m ?, but it is sensitive to gas composition, and its large-scale application still needs breakthroughs;

　　05运行优化难题：多变量协同控制如走钢丝脱硫系统需精准调控吸收剂浓度、液气比、温度等十余项参数。以某电厂为例，烟气SO?浓度波动±10%时，若未及时调整钙硫比，脱硫效率可能骤降8%，同时副盐生成量增加30%。此外，煤气中CO?含量过高会消耗碳酸钠吸收剂，导致脱硫效率与药剂成本“双失控”?。

　　05 Operation optimization challenge: Multi variable collaborative control such as steel wire desulfurization system requires precise regulation of more than ten parameters including absorbent concentration, liquid gas ratio, temperature, etc. Taking a power plant as an example, when the concentration of SO ? in flue gas fluctuates by ± 10%, if the calcium sulfur ratio is not adjusted in time, the desulfurization efficiency may drop sharply by 8%, and the amount of by-product salt production may increase by 30%. In addition, excessive CO ? content in coal gas can consume sodium carbonate absorbent, leading to a "dual out of control" of desulfurization efficiency and chemical cost.

　　破局之道:技术创新正在路上面对这些挑战，行业正探索新路径：纳米改性吸收剂提升反应效率、膜分离技术强化废水回收、AI算法实现参数智能调控……正如某环保工程师所言：“每个难点背后，都是技术迭代的契机。”唯有持续攻坚，方能让蓝天保卫战从“达标”走向“高效”。

　　The way to break through: Technological innovation is on the way to face these challenges, and the industry is exploring new paths: nano modified absorbents to improve reaction efficiency, membrane separation technology to enhance wastewater recovery, AI algorithms to achieve intelligent parameter control... As a certain environmental engineer said, "Behind every difficult point is an opportunity for technological iteration." Only by continuously tackling challenges can the blue sky defense battle move from "standard" to "efficiency".
