METHOD AND ARRANGEMENT FOR COLLECTING AND REMOVAL OF ACID MIST FROM AN ELECTROLYTIC CELL

摘要

The invention relates to a method and to an arrangement for collecting and removal of acid mist from an electrolytic cell (1). The arrangement comprises a cover (3) for covering an open top of a container (2) of the electrolytic cell (1) so that a space (9) is formed between a surface (10) of electrolyte (6) contained in the container (2) and the cover (3), a decontamination system (7) provided with an acid mist suction channel (8) terminating in an upwards facing inlet opening (13) in the space (9), and a cleaning arrangement (14) for spraying the upwards facing inlet opening (13) with washing fluid (15). The cleaning arrangement (14) has a fluid nozzle (16). The fluid nozzle (16) is in the acid mist suction channel (8). The fluid nozzle (16) is arranged to spray washing fluid (15) at least downwards into the acid mist suction channel (8).
