Activated carbon for flue gas treatment in waste incineration
With the acceleration of the urbanization process, the amount of waste generated is increasing day by day, and waste incineration and treatment have become important tasks in urban environmental management. In this process, as an efficient adsorbent material, powdered activated carbon plays a crucial role by virtue of its unique physical and chemical properties.
The Role of Activated Carbon in Waste Incineration
1.Removing Dioxins
Dioxins are very harmful chemicals produced when waste is burned. They can hurt people’s health and damage the environment. Powdered activated carbon is like a super sponge with lots of tiny holes and a huge surface area. When the smoke from burning waste passes through the carbon, the dioxins get trapped in these tiny holes. This helps clean the smoke and reduces the amount of dioxins released into the air, making the environment safer.
2.Adsorbing Heavy Metals
There are often different kinds of heavy metal elements in the garbage, like mercury, lead, and cadmium. When the garbage is burned, these heavy metals will be carried out with the smoke. Powdered activated carbon is really good at holding onto heavy metals. It can fix the heavy metal ions in the smoke on its surface, either by physical adsorption or chemical adsorption. For example, for mercury, which can easily turn into a gas, powdered activated carbon can effectively hold it and stop it from going into the air. This helps us get rid of heavy metals effectively and reduces the risk of heavy metal pollution to the environment caused by waste incineration.
3.Reducing Acidic Gases
When we burn garbage, some acidic gases will also be produced, such as sulfur dioxide and hydrogen chloride. Activated carbon can work as a helping tool. To some extent, it can hold onto the acidic gas molecules and make the concentration of these gases in the smoke lower. This makes the smoke cleaner and less harmful when it’s released into the air.
In short, powdered activated carbon is like a superhero for cleaning up the smoke from waste incineration. It catches harmful chemicals, heavy metals, and acidic gases, making the air cleaner and safer for everyone!
