TECHNOLOGICAL LINE flue gas cleaning electrolytic production of aluminum

摘要

The proposed technical solution relates to the electrolytic production of aluminum and can be used for purification of exhaust gases with the upper current lead electrolyzers with self-baking anodes. Process flue gas cleaning line electrolytic production of aluminum, comprises a block of dry cleaning, comprising at least one hopper fresh alumina, at least one vertical adsorbing reactor equipped with a unit for feeding the flue gases, the supply of fresh alumina node supplying exhaust alumina node, at least one a tubular filter consisting of filter chamber and spent alumina hopper associated with the storage hopper and the adsorbing reactor outlet gases from the filtration system second camera system output the purified gas into the atmosphere. Nodes feeding fresh and spent alumina formed as chutes mounted at an angle in the housing adsorbing reactor above the neck. gas removal system from the filter bag filter chamber is connected to the wet scrubbing unit, comprising at least three scrubber provided with supply and discharge lines soda solution. Droplet, flue, chimney connected to output of the purified gas into the atmosphere. The line feeding fresh alumina can be provided with the device for controlling the flow of alumina. alumina feed exhaust line may be provided with a device for controlling the flow of alumina. Hopper spent alumina can be connected to the hopper of fresh alumina conveying line equipped with a device for controlling the flow of alumina. 3 ZP f.p.m 1 yl.
