Abstract
The utility model discloses an electrolytic aluminium anode preheating device which comprises a ring-shaped track, wherein one part of the ring-shaped track is arranged in an insulation heat exchange room; one end of the insulation heat exchange room is connected with the inlet of a flue gas pipeline, and the other end of the insulation heat exchange room is connected with the outlet of the flue gas pipeline; and the ring-shaped track is provided with an anode pallet truck. According to the electrolytic aluminium anode preheating device, the gas in the flue gas pipeline is led into the insulation heat exchange room, so that heat exchange is carried out between the high-temperature gas and an anode; therefore, the residual heat is fully utilized, and the electric energy is saved; and the electrolytic aluminium anode preheating device is beneficial to the production of an electrolytic cell.
Description
Technical field
The utility model belongs to the electrolytic aluminum field, is specifically related to a kind of anode preheating device.
Background technology
When electrolytic aluminum smelting process Anodic more renews the utmost point, after changing, the new utmost point just can reach the total current normal level in about 16 ~ 24 hours, major cause is that the temperature of anode of newly changing is low, heat in a large amount of absorption electrolyzers after heat exchange, the ionogen cooling of contact anode forms non-conductive Condensed electrolyte layer, production causes unfavorablely to electrolyzer, causes simultaneously a large amount of energy losses.
The flue-gas temperature of discharging from smoke pipe in the electrolytic aluminum process is between 100 ~ 150 ℃, and a lot of enterprises all are with directly discharging after the gas cleaning, have wasted large energy.
The utility model content
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, and a kind of electrolytic aluminium anode primary heater unit that can take full advantage of flue gas heat preheating anode is provided.
The technical solution of the utility model realizes in the following manner: a kind of electrolytic aluminium anode primary heater unit, comprise circular orbit, the part of circular orbit is arranged in the insulation heat exchange room, insulation heat exchange room one end links to each other with the flue import, the other end links to each other with the flue outlet, and circular orbit is provided with the anode tray car.
Described insulation heat exchange room and flue import connecting place are provided with filtration unit.
The utility model is guided to the gas in the smoke pipe in the insulation heat exchange room, so that high-temperature gas and anode generation heat exchange, and then taking full advantage of surplus heat, saves energy is conducive to electrolyzer production.
Description of drawings
Fig. 1 is use view of the present utility model.
Fig. 2 is anode and anode tray bassinet structure synoptic diagram.
Embodiment
As depicted in figs. 1 and 2, electrolytic aluminium anode primary heater unit of the present utility model, comprise circular orbit 1, the part of circular orbit 1 is arranged in the insulation heat exchange room 2, insulation heat exchange room 2 one ends link to each other with the flue import, the other end links to each other with the flue outlet, and circular orbit 1 is provided with anode tray car 4.
In the utility model, hot flue gas is along A to moving, and anode 3 is placed on the anode tray car 4, along B to moving.Hot flue gas can be heated to anode block about 80 ~ 100 ℃ by after the insulation heat exchange room 2, when the electrolyzer change poles, pulls out anode after the heating in the insulation heat exchange room to the workshop and is placed in the electrolyzer.
Anode after the heating can reach total current at 8 hours, whenever changed an anode and can save 50 ℃ of electricity, also can prevent that the carbon piece that washes away from entering impact production in the electrolyzer simultaneously, and the breeze in the electrolyzer reduces, and reduces electrolytical resistance, improves its conductance.
Described insulation heat exchange room 2 is provided with filtration unit with flue import connecting place.Can further filter like this impurity in the hot flue gas.
