Abstract
The present invention discloses a method for improving the radiation of the casing of a large aluminum electrolytic tank. The present invention uses a method for welding a plurality of radiating fins (2) at the outer side of the casing (1) to improve the radiating capacity of the casing, and solves the problem of aluminum electrolytic tanks with a super-large capacity that the casing is seriously distorted due to the overhigh temperature of the casing to cause an inner liner at the side of the tank to be damaged.
Description
Affiliated technical field
The present invention relates to large-scale aluminum electrolytic cell, relate in particular to and strengthen 300KA and the above a kind of method of strengthening the heat radiation of large-scale aluminum electrolytic cell pot shell of 300KA.
Background technology
Along with the Aluminum Electrolysis Production development of technology, the capacity of electrolyzer is increasing, and promptly increasing by the strength of current of electrolyzer, the thermal value of cell body is increasing thereupon.In order to keep the electro-thermal equilibrium of electrolyzer, will inevitably increase the thermal load of pot shell.The domestic 300KA level electrolyzer that has, before the method for not taking special heat radiation, the shell temperature of groove sidepiece is up to more than 450 ℃.Like this, the ionogen of groove thorax inwall is difficult for forming complete crust, the breakage of washing away meeting generation cell wall liner of high-temperature fusant.Simultaneously, because the temperature of pot shell is too high, cause that the intensity of pot shell reduces, produce gross distortion under the effect of pot shell internal stress, the groove liner is damaged thereupon, has reduced the time limit of service of electrolyzer.This situation is proved by the early damage of 280KA Thoughs.In order to reduce the temperature of pot shell, present 300KA groove has to adopt force ventilated way sometimes, blows pot shell with pressurized air, makes its cooling, and this obviously can not be as the terms of settlement under the ordinary production state.
Summary of the invention
Technical problem to be solved by this invention provides simple a kind of method of strengthening the heat radiation of large-scale aluminum electrolytic cell pot shell.Under the constant situation of electrolytic bath shell structure, only need some radiator element of welding on the outer wall of pot shell, logical superheated conduction, the width of cloth are penetrated, can strengthen the heat-sinking capability of pot shell effectively, just as radiator can be strengthened heat radiation, by the convection current of air, take away heat, reach the purpose of pot shell heat radiation.
The invention is characterized in:
A. do not need the pot shell structure of electrolyzer is done any change, only around the electrolyzer pot shell on, weld some radiator element.
B. the specification of radiator element and quantity can be determined according to the size of electrolyzer capacity, and for 300KA～500KA electrolyzer, the specification of radiator element is: long 400～800mm, wide 150～400mm, thick 5～25mm.The radiator element quantity of every platform trough is 70～300.
C. the welding position of radiator element: avoid electrolyzer and shake backboard support, the upper end of radiator element near or reach the downside of groove along plate, the lower end of radiator element will be apart from electric tank cathode rod iron upside 100～200mm.Radiator element is that vertical direction is welded on the pot shell outer side wall.
D. the material of radiator element is common charcoal steel.
Advantage of the present invention and effect are: strengthening large vol electrolyzer pot shell heat-sinking capability, is the effective measure of avoiding the pot shell gross distortion, reducing inner lining damage, can improve the time limit of service of electrolyzer significantly, promptly prolongs cell life.The present invention is applied to the heat radiation of electrolyzer pot shell dexterously to the principle of radiator heat radiation, is simple, a good method of obvious results.
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail.

Fig. 2 is that the master behind the electrolyzer radiation fin looks synoptic diagram.
Fig. 3 is the schematic side view behind the electrolyzer radiation fin.
Embodiment
In the outer periphery of electrolyzer pot shell 1, weld some radiator element 2.The welding position, the left and right sides of radiator element 2, make avoid electrolyzer about it shake backboard support 3, the welding position up and down of radiator element 2 will make its upper end get close to the downside of groove along plate, and makes them down more than the end distance electric tank cathode rod iron 4 upside 50mm.According to varying in size of tankage, determine length, width, thickness, the quantity of its radiator element.For 300KA～500KA electrolyzer, the length of radiator element is 400～800mm, and width is 150～400mm, and thickness is 5～25mm, and the quantity of every platform trough welding radiator element is 70～300.Radiator element is the vertical direction welding.The material of radiator element is common charcoal steel.The shape of radiator element can be an orthogonal, also can not make orthogonal, and is for example trapezoidal.
Claims (3)
1. a method of strengthening the heat radiation of large-scale aluminum electrolytic cell pot shell is characterized in that welding some radiator element around pot shell.
2. a kind of method of strengthening the heat radiation of large-scale aluminum electrolytic cell pot shell according to claim 1, it is characterized in that for 300KA～500KA large vol aluminium cell, the specification of radiator element is long 400～800mm, wide 150～400mm, thick 5～25mm, 70～300 of every platform trough welding radiator element, the material of radiator element is common charcoal steel.
3. a kind of method of strengthening the heat radiation of large-scale aluminum electrolytic cell pot shell according to claim 1, the welding position that it is characterized in that radiator element, avoid the backboard support that shakes of electrolyzer about it, its the upper end near groove along the plate downside, the distance of its lower end and electric tank cathode rod iron upside is 100-200mm, and radiator element vertically is welded on the outer wall of pot shell.
