活性炭制造与定制化吸附解决方案

Dioxin Removal · Flue Gas Treatment · Mercury Adsorption

垃圾焚烧

Hazardous and municipal waste incineration produces flue gas loaded with dioxins, furans, mercury and acid gases. Powdered activated carbon injection combined with fabric filtration captures these micro-pollutants reliably, while fixed-bed polishing secures compliance with strict TEQ limits under variable furnace loads.

垃圾焚烧用活性炭 —— 烟气净化解决方案

垃圾焚烧是生活垃圾与工业废弃物无害化处置的重要方式。但焚烧烟气中含有二噁英、汞蒸气、重金属、VOCs 及恶臭物质等剧毒污染物。活性炭喷射或固定炭床吸附已成为深度净化烟气的成熟可靠技术。

我们的高性能粉状与颗粒活性炭针对焚烧尾气治理定制,广泛应用于生活垃圾焚烧厂、危废焚烧设施及污泥焚烧项目。

核心应用场景

  1. 焚烧烟气二噁英去除 吸附多氯二苯并二噁英与呋喃(PCDD/Fs)。活性炭捕集垃圾燃烧过程中产生的微量二噁英分子,是控制二噁英排放最广泛采用的方法。
  2. 汞与重金属蒸气捕集 去除烟气中的元素汞及其他挥发性重金属。汞难以被常规洗涤器捕集,活性炭可实现深度去除,满足环保排放限值。
  3. VOCs and Odor Control 吸附垃圾燃烧过程中产生的残留挥发性有机物与恶臭气体,减少焚烧厂周边异味污染,改善周边空气质量。
  4. 危废焚烧烟气精制 针对危废焚烧线,对布袋除尘与洗涤后的烟气进行深度净化,拦截微量持久性有机污染物与有毒重金属。
  5. 污泥焚烧烟气治理 处理污泥热焚烧尾气,控制二噁英与汞的释放,帮助污水处理厂安全处置脱水污泥。

为何选择我们的垃圾焚烧活性炭

  • 优化微孔结构,对二噁英与汞吸附容量高
  • 耐温性好,在烟气工况下性能稳定
  • 细粉炭适用于干法喷射系统,颗粒炭适用于固定吸附塔
  • 吸附速度快,适合烟气管道内的短接触时间
  • 灰分杂质低,粒径均匀,喷射分布均匀
  • 可为大型生活垃圾焚烧与危废处置项目批量供货

工作原理

粉状活性炭喷入高温烟道,有毒有机分子与汞蒸气被快速吸附至炭表面,载污炭随飞灰由布袋除尘器一并捕集。固定床工艺中,烟气通过颗粒炭床层,污染物被截留在炭孔内。

服务行业

Recommended starting ranges for flue-gas duty. Final values depend on the gas composition, injection system and the emission limits in your permit.

炭型 碘值 典型粒径 适用工况 选型效果
Powder carbon (injection grade) 800–1000 mg/g 200–325 目 Dry injection upstream of baghouse Captures dioxins and mercury in one step
Sulfur-impregnated carbon 900–1100 mg/g 4×10 mesh Mercury polishing on low-dust gas High mercury uptake at low dose
Coal-based extruded carbon 900–1100 mg/g 3 mm / 4 mm Fixed-bed polishing after filtration Low dust, stable long-cycle bed
蜂窝炭 600–900 mg/g 100×100×100 mm

100×100×50 mm

Low-dust tail-gas treatment Very low airflow resistance

处理流程

From furnace outlet to compliant stack.

The exact train is confirmed against your flue-gas analysis, operating temperature and the TEQ limits in the discharge permit.

  1. 01Rapid quench to the adsorption temperature window
  2. 02Powder carbon injection into the duct
  3. 03Baghouse filtration with the carbon captured on bags
  4. 04Fixed-bed polishing for mercury and residual PCDD/F
  5. 05Stack monitoring with spent-carbon disposal support
