Adsorption of dioxins and furans: During the waste incineration process, some toxic dioxins and furans are produced. Powdered activated carbon has an extremely high specific surface area and good adsorption properties, which can effectively adsorb these harmful substances and reduce their emission concentration.
Removal of heavy metals: The flue gas produced by incineration may also contain heavy metals. Through the adsorption capacity of activated carbon, heavy metal elements in the flue gas, such as mercury, lead and cadmium, can be effectively captured.
Removal of acidic gases: Acidic gases (such as HCl, HF, SO2, etc.) produced by waste incineration can also be further adsorbed by activated carbon after combining with certain chemicals (such as alkaline substances).
Used in combination with other flue gas purification equipment: Powdered activated carbon is usually used in conjunction with bag filters, electrostatic precipitators and other equipment. While the flue gas is being adsorbed, the activated carbon particles are also separated from the airflow, thereby improving the overall purification efficiency.
In practical applications, powdered activated carbon can be evenly distributed into the flue gas through the injection system for sufficient mixing and adsorption reactions. Used activated carbon is collected and processed together with other filter dust to ensure protection of the environment and human health.
