Device for precipitating dust from the quench fumes in coke-quenching towers

摘要

A device (2) for precipitating dust from the quench fumes in coke-quenching towers (1) is shown and described, which consists of a plurality of precipitator plates (4) built at a mutual spacing and mutually parallel into the exhaust stack (3) of the coke-quenching tower (1). The precipitator plates (4) are arranged in vertical planes, forming a flow channel; in each case a plurality of precipitator plates (4) is combined to form a precipitator body (15). The precipitator plates (4) or the precipitator bodies (15) are arranged obliquely. In detail, the precipitator plates (4) or the precipitator bodies (15) are arranged in the shape of a V or W. In order to achieve an even more extensive limitation of pollution, the precipitator plates (4) or precipitator bodies (15) are associated with spray nozzles (19) for initial spraying, the spray nozzles (19) being arranged on the flow-affected sides (20) of the precipitator plates (4) or precipitator bodies (15). According to the invention, the precipitator plates (4) or precipitator bodies (15) are sprayed during the coke quench, i.e. during the quenching time, with a liquid, preferably with water, and in particular during a spraying time within the quenching time.
