Main sources: metal dust particles generated in the metal melting process of the hardware industry, die-casting industry, foundry industry, and SO2, NOX harmful gases generated during the combustion of diesel oil (heavy oil), and diesel fuel (heavy oil) when the generator is working. Exhaust gas generated during the process.
Hazard: Furnace exhaust gas and generator black smoke are the main causes of acid rain, resulting in large air pollution, especially direct damage and indirect impact on the on-site operators, crops and soil near the factory.
Treatment method: swirling water spray method + lye absorption
