| In the process of plasma melting, the emissions containing toxic acid gases and fine particles of dust must be governance. The smelting exhaust from the plasma furnace entering the second combustion chamber, air dilution cooling system, primary ceramic filters and secondary ceramic filters, harmful particles and toxic gas after combustion, settlement, cooling, filtering and adsorption process, not only the harmful components obtained governance, and meet European emissions standards, but also can collect the valuable dust return plasma melting system, turning waste into treasure. |
