FIELD: oil-and-gas industry.
SUBSTANCE: device comprises gas collection bell suspended over perimeter of anode jacket connected with gas ducts of centralised gas withdrawal system and branch pipes. At least two branch pipes are arranged symmetrically at central part of lengthwise sides, at the zone of maximum temperatures of gas collection bell and connected with gas ducts of centralised gas withdrawal system. Branch pipes feature decreased outlet cross-section as compared to that of inlet. Air feed holes are made at gas collection bell zone adjoining the branch pipe locations. Extra air feed holes are made at branch pipe bases. Said extra holes are made in mirror axis of branch pipes while hole height-to-pipe base makes 0.22-0.27.
EFFECT: sufficient rarefaction for removal of anode gases, decreased emissions in electrolytic cell case.
