随着我国环保政策持续加码,工业挥发性有机物(VOCs)治理成为大气污染防治的重点领域。近日,活性炭吸附脱附催化燃烧(CO)技术凭借其高效、节能、环保的特性,在化工、涂装、印刷等行业广泛应用,为VOCs治理提供了创新解决方案,助力企业实现绿色低碳转型。
技术原理:循环利用,高效净化
活性炭吸附脱附催化燃烧技术结合了吸附浓缩与催化氧化两大核心工艺。首先,活性炭通过高孔隙率结构吸附VOCs废气,实现污染物的富集;随后,通过热空气或蒸汽对活性炭进行脱附,将浓缩后的高浓度废气引入催化燃烧装置。
在催化剂(如贵金属或金属氧化物)作用下,VOCs在250-350℃的低温环境中发生氧化反应,分解为二氧化碳和水,净化效率可达95%以上。该技术不仅避免了传统高温焚烧的高能耗问题,还能通过余热回用系统降低运行成本,实现能源循环利用。
应用优势:经济环保双赢
与传统治理技术相比,该技术具有显著优势:
-
节能降耗:催化燃烧温度较直接燃烧降低40%-50%,结合余热回收,综合能耗减少30%以上;
-
安全稳定:活性炭阻火设计及催化剂的抗中毒性能提升,保障设备长周期运行;
-
适应性强:可处理苯类、酯类、酮类等多种复杂VOCs组分,浓度适用范围广(200-5000mg/m³);
-
低碳减排:无二次污染,碳排放量较传统工艺下降20%。
行业实践:标杆案例引领风向
在浙江某大型汽车涂装企业,该技术成功落地后,VOCs年排放量从120吨降至5吨以下,设备运行成本降低25%,获评省级环保示范项目。此外,山东某石化园区采用“活性炭吸附+CO”组合工艺,实现VOCs去除率98.2%,年节约标煤超800吨,经济效益与环境效益显著。
政策驱动,前景广阔
随着《“十四五”挥发性有机物综合治理方案》的推进,各地对VOCs排放标准日趋严格。业内专家指出,活性炭吸附脱附催化燃烧技术契合“双碳”目标需求,未来可通过智能化控制系统、新型催化剂研发进一步优化效能,预计到2025年市场规模将突破50亿元。
活性炭吸附脱附催化燃烧技术的推广,标志着我国VOCs治理迈向“高效化、资源化”新阶段,为打赢蓝天保卫战注入强劲动力。
