Active Carbon enhanced Sodium Bicarbonate for Bronze Recycling Foundry

The process of recovering bronze from scrap metal and industrial waste represents a significant environmental challenge, primarily due to the polluting emissions generated during smelting. The fumes emitted contain harmful substances such as sulfur oxides (SOx), hydrochloric acid (HCl), hydrofluoric acid (HF), and heavy metals. To address these issues and reduce environmental impact, it is essential to use fume purification systems based on special additives such as active carbon enhanced sodium bicarbonate mixed.

An effective purification system for bronze recovery can include the use of active carbon enhanced sodium bicarbonate, which performs a dual function: it reduces the acids present in the fumes and captures heavy metals and other harmful substances. The combination of these two components allows for more efficient fume treatment, simplifying the process thanks to the use of a single dispenser.

Solution with Active Carbon Enhanced Sodium Bicarbonate

This type of system uses active carbon enhanced sodium bicarbonate which is fed into the filtering system through a single dispenser. This eliminates the need for separate stations for grinding the bicarbonate and distributing the activated carbon, optimizing time and reducing operating costs. The combination of the two components in additive form ensures the simultaneous reduction of oxides, acids, and heavy metals.

Flue Gas Cleaning with Active Carbon enhanced Sodium Bicarbonate

FAQ

During the recovery of bronze, the emitted fumes contain Sulfur Oxides (SOx), Hydrochloric Acid (HCl), Hydrofluoric Acid (HF), and heavy metals, such as Lead (Pb), Cadmium (Cd), and Mercury (Hg). These pollutants derive from the composition of the scrap metals and the use of additives during melting. A filtering system based on enhanced sodium bicarbonate effectively neutralizes these compounds, reducing the environmental impact.
During the bronze melting process, scrap metal is heated to high temperatures, generating fumes containing polluting substances. The use of sodium bicarbonate enhanced with activated carbon allows for the simultaneous neutralization of acids (such as HCl and HF) and the absorption of heavy metals and other toxic compounds. This solution simplifies fume treatment, making it more efficient and economically sustainable.
Sodium bicarbonate, combined with activated carbon, serves a dual function. On one hand, it neutralizes the acids in the fumes, transforming them into non-hazardous solid salts. On the other hand, with the addition of activated carbon, it also captures heavy metals and other harmful substances. This multi-component approach ensures a complete reduction of pollutants in a single step.
