VERFAHREN UND VORRICHTUNG ZUR QUECKSILBERABSCHEIDUNG BEI DER ZEMENTKLINKERHERSTELLUNG
A method and a device remove mercury from exhaust gases during a production of cement clinker. The device contains a pre-heating stage, a feed point for raw materials required for the production of the cement clinker, a rotary kiln for burning the raw materials, a filter stage for removing dust from the exhaust gases conducted in the main flow, and a raw mix mill for partially mill drying the raw materials. A circuit for the mercury in the exhaust gases is formed between the pre-heating stage and the raw mix mill or the filter stage. To achieve good mercury removal at low cost, a sub-flow of 1 to 30 volume percent of the exhaust gases is branched off from the main flow of the exhaust gases having a temperature of at least 300° C. A separator and thereafter at least one stage for removing mercury are arranged in the sub-flow.
