Method and apparatus for dedusting and absorption of contaminating gases being the exhaust gases of waste-incinerating devices and hot-air cupola furnaces

摘要

The invention relates to a method for dedusting and absorption of contaminating gases in exhaust gases of waste-incinerating devices and hot-air cupola furnaces. In the essence, mud-containing circulation water is atomized in the exhaust gas, whereby dry waste mud is produced. After dust precipitation, the gas is fed to a scrubber which removes the contamination gases. The scrubbing liquid is neutralized and, possibly, mixed with ash and fed back into the circulation.
