Embodiment Construction
[0040] Devices for collecting and removing gases are installed in the reduction tank. A reduction tank is a device for the production of aluminum by reducing a melt and typically consists of an anode, a point alumina feeder with a breaker, a collector beam with gas lines and caps, and a hood. All structural elements of the claimed device are fixed on the collector beam 1 . The cover of the reduction tank 2 is made of a separate cover, inside which the guide element 3 is firmly mounted horizontally with respect to the electrolyte casing of the melt. Guiding elements can be structured as plates or protrusions ( Figure 4 and Figure 5 ), the plate or protrusion is made of the material used to make the cover, such as aluminum. The number of guide elements is determined by the velocity of the flow between the guides, and it is necessary to ensure that the airflow velocity is higher than 2m / s and lower than 7m / s to exclude the gas escaping from the reduction tank and carry the a...
