The invention relates to a flue gas collection device, in particular to a hot anode scrap flue gas collection device for an aluminum electrolysis cell with a pre-baked anode. According to the hot anode scrap flue gas collection device for the aluminum electrolysis cell with the pre-baked anode, a box door is arranged on a box body, a clamping device is arranged at the bottom of the box body, and aflue gas exhaust port is formed in the side wall of the box body. The hot anode scrap flue gas collection device for the aluminum electrolysis cell with the pre-baked anode has the advantages that flue gas in the hot anode scrap cooling process can be well collected in the box body and taken away by negative pressure of a purification system, so that the workshop environment is not polluted; dueto the fact that the device is fixed on an anode supporting plate, existing trailer transportation is not affected, and the floor space of an electrolysis workshop is not additionally occupied; the device does not need to move in the using process, and only the box door needs to be manually opened, so that the operation is simple, and the labor intensity is low; and the device has no effect on theoriginal workshop arrangement, factory building structure and production equipment, not only can be applied to a newly-built electrolysis workshop, but also can be well applied to existing workshop configuration increasing, and has excellent universality.
