HARMFUL GAS PROCESSING EQUIPMENT FOR ELECTROLYTIC CELL

PROBLEM TO BE SOLVED: To provide a harmful gas processing equipment which restrains damage caused by diffusion of harmful gas into electrolyte which gas is generated around an electrode in the electrolyte, and can easily and surely detect abnormality of harmful gas processing system. SOLUTION: In order to capture harmful gas generated around an electrode 13, from electrolyte 11 together with it, a suction pump 34 is arranged in a processing pipe channel 33 stretching from the electrolytic cell 12. On the spouting side of the suction pump 34 in the processing pipe channel 33, a harmful gas cleaning part member 35 is arranged on the upper stream side, and a flow rate sensor 36 for detecting abnormality of the processing system is arranged on the downstream side. Thereby, diffusion of harmful gas into the electrolyte 11 can be restrained. For example, when the harmful gas cleaning part member 35 is normal without generating clogging, the flow rate sensor 36 measures the flow rate corresponding to the normal state. When clogging is generated in the harmful gas cleaning part member 35, the flow rate is this case becomes lower than the normal case.
