Treatment system gas dust extraction flue gas of the cement kiln and method of treatment

摘要

A system for treating gas extracted from cement kiln comprising: a probe for extracting a part of combustion gas while it cools, a channel exhaust gas furnace, which runs from an inlet end of a furnace cement a bottom cyclone; a classifier for separating coarse powder from dust contained in the combustion gas extracted by said probe; wet dust collector for collecting dust of the extracted gas containing fine powder discharged from said classifier; and a device for feeding a sulfurizing agent for sulfurizing lead contained in the exhaust gas of the furnace to said wet dust collector wherein dust collection including fine powder discharged from the classifier, desulfurization of the exhaust gas of the cement kiln and sulfurization of lead included in the exhaust gas of the cement kiln are performed simultaneously in the wet dust collector.
