In today's society, with the continuous acceleration of urbanization, domestic waste disposal has become a hot topic of concern. Incineration, as a common garbage disposal method, can effectively reduce the volume of garbage, but it also produces a large number of harmful gases and particles, causing pollution to the environment. As an important purification material, powdered activated carbon is becoming the key to solving the pollution of incineration flue gas. However, choosing the right powdered activated carbon can be challenging, as there are many types on the market, each with different characteristics. Activated charcoal
One. Functions of powdered activated carbon
Powdered activated carbon is a very amazing material, it has a very large specific surface area and a lot of tiny pore structures. This enables powdered activated carbon to efficiently adsorb various harmful substances, thereby achieving the purpose of purifying flue gas. When garbage is incinerated, the flue gas produced contains a large amount of harmful gases and particulate matter, such as:Sulfur dioxide, nitrogen oxides, heavy metals, etcPowdered activated carbon can quickly adsorb these harmful substances, purify flue gas, and protect the environment.
Wood Activated Carbon:Wood activated carbon is made of wood as raw material, and its pore structure is relatively uniform, which makes it have a good adsorption effect. In addition, wood activated carbon also has strong high temperature resistance, which is suitable for flue gas purification in high temperature environments.
Coir Activated Carbon:Coconut shell activated carbon is made of coconut shell as raw material, which has high hardness and large porosity, so it has strong adsorption capacity. Coconut shell activated carbon has a remarkable effect on adsorbing harmful substances and is a powdered activated carbon with excellent performance.
Coal activated carbon: Coal activated carbon is made of coal as raw material, its pore structure is relatively complex, and the adsorption rate is relatively fast. Coal-based activated carbon performs well in flue gas purification, especially for the adsorption of particulate matter.
There are several factors to consider when choosing the most suitable powdered activated carbon:
1.Smoke composition:According to the characteristics of the flue gas composition produced by incineration of garbage, powdered activated carbon with appropriate adsorption characteristics is selected.
2.High temperature resistance:Considering the working temperature of the incineration equipment, select powdered activated carbon with good high temperature resistance to ensure its stable operation in a high-temperature environment.
3.Value for money:Comprehensively consider the adsorption effect, high temperature resistance and other factors, choose the most cost-effective powdered activated carbon to ensure that the economic and practical effect is achieved.
Through an in-depth understanding of the characteristics of different types of powdered activated carbon, we can provide more scientific and green solutions for the flue gas purification of domestic waste incineration. Let us devote ourselves to the cause of environmental protection and help the dream of a fresh blue sky!
