专利说明:
The invention relates to the field of aluminum production, in particular, by electrolysis of molten salts in electrolyzers with longitudinal placement in the housing. Known busbar aluminum cell with two-sided supply of current to the anode bus through the drain located at the input and output ends of the cathode casing, the cathode rods of which are divided into groups connected to self-contained packages of cathode tires, in which the current to the input and output cathodes t is asymmetrical in a ratio close to 2: 1. A disadvantage of the known technical solution is a reduction in production. electrolysis cells with an increase in the unit capacity of the electrolysis cell due to the increase in current, especially in series with a nominal current above 100 kA. As the current of the cell increases, the magnetic field and electromagnetic forces in the molten aluminum increase. Uncompensated electromagnetic forces induce the circulation of the melt and, distortion of its level, which leads to a decrease in the performance of the electrolysis process. The purpose of the invention is to improve the performance of high unit capacity electrolyzers with a high degree of compensation of electromagnetic forces in the melt due to the redistribution of the magnetic field in it. To do this, packages of cathode tires of groups of rods closest to the input end of the cathode casing are connected to the stands located at the input end, and the remaining groups with cages located along the sides of the cathode casing of the subsequent electrolyzer. At the same time, if the rolling rods are divided into two groups, then the one located to the side of the board is connected to the anode bus in its middle, and when dividing the cathode rods of one side into three groups, the stoves are placed so that their connection with the anode bus. the length into sections of length 1: 3 and 2: 3, respectively. , FIG. 1 shows a diagram of the bus-bar when dividing the cathode rods of one side of the cathode casing into two groups, B, plan; in fig. 2 - the same, when divided into three groups. The electrolyzers 1 and 2 are located one after the other along the longitudinal axis of the housing, connected in a series electric circuit by a busbar containing anode tires 3, 4, stands 5, 6ji located at the input end of the cathode housing 7, b; cathode rods 9, divided into two groups 10 and 11, 12 and 13 from each side, respectively (Fig. 1), or three groups 10 and 11, 12 and 13, 14 and 15 (Fig. 2), each: and of which The cathode busbars 16, 17, 18, 19, 20, 21 are connected to the independent pack. Moreover, the bus packs 16 and 18 are connected to the stoppers 5 and 6, and the bus packs 17 and 19 to the stoppers 22, 23 located along the sides cathode housing when the cathode rods are divided into two groups. If the cathode rods are divided into three groups of 10, 11/14, and 12, 13, 15, then the packages of cathode tires 17 and 19 are connected to the sinks 24 and 25, and the packages of the tires 20 and 21 are connected to the sinks 26 and 27. The current from Stacks 24, 25 and 26, 27 are fed to anode tires 3 and 4 at points 28 and 29, which divide the length of the tires in ratios 1: 3 and 2: 3. The implementation of a current-equivalent according to the above scheme of bus-bar leads to a significant decrease in the horizontal components of the magnetic field, equalizing their values over the area of the liquid cathode. At the same time, a significant reduction in the vertical components of the floor in the corners and their differences along the sides of the cathode shell is achieved. The use of this busbar allows you to increase the current in the electrolyzer by 30%, the current efficiency to bring dg 70 P No. 10 11/7 3; g
