HYDROGEN GAS EXHAUSTING STRUCTURE FOR ELECTROLYSIS UNIT OF BALLAST WATER TREATMENT SYSTEM

摘要

Disclosed is a hydrogen gas discharging structure capable of safely discharging hydrogen gas, separated from electrolyzed water produced from an electrolytic bath of a ballast water treatment apparatus, to the atmosphere. According to the present invention, the hydrogen gas discharging structure for an electrolytic unit of the ballast water treatment apparatus comprises: a hydrogen gas separator (512) formed in a discharge line (511) of the electrolytic bath (510); an electrolyzed water supply line (513) and an electrolyzed water pump (514) formed to inject the separated electrolyzed water to a main ballast line (10) from the hydrogen gas separator (512); a dilution chamber (550) formed in an upper end of the hydrogen gas separator (512), and integrated into an upper end portion of the hydrogen gas separator (512) while having an internal sealed space as the volume is extended and as being blocked from the outside; a bent valve (551) formed in an upper outlet (512a) of the hydrogen gas separator (512) to discharge hydrogen gathered in an upper end of the hydrogen gas separator (512) to the dilution chamber (551); a discharge hole formed in an upper end of the dilution chamber (550), and extending outside an upper deck of a ship to discharge diluted gas inside the dilution chamber (551) into the atmosphere after a diluted gas discharge line is connected; a blower (560) for putting air in the dilution chamber (550); and an air blast pipe (561) extending to put air for dilution from the discharge hole of the blower (560), and introduced inside the dilution chamber (550).
