Dioxin and mercury control on flue gasPowder carbon injected before the baghouse; stack PCDD/F kept below the 0.1 ng TEQ/Nm3 permit limit.
Dioxin Removal · Flue Gas Treatment · Mercury Adsorption
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.
沟通您的项目行业概述
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。
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。
生活垃圾焚烧厂、危废焚烧设施、污泥焚烧站及工业废弃物热处理厂。

常用炭型: 粉状 · 柱状 · 浸渍活性炭
产品参数
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
The exact train is confirmed against your flue-gas analysis, operating temperature and the TEQ limits in the discharge permit.

常见问题
需要更快评估?请在询价时附上现有工艺数据。
Dry injection rates commonly fall between 50 and 150 mg/Nm3, tuned against stack test results. We help you set the starting dose and adjust after the first measurement campaign.
Yes. Sulfur-impregnated grades are available for low-temperature mercury polishing, and we can compare them against standard powder carbon on your gas data.
Fly ash with captured carbon is collected as hazardous waste under local rules. We provide technical data sheets that support your disposal classification.
Share your flue-gas analysis and permit limits. We can arrange bench adsorption tests and a sample batch for on-site injection trials.
