Detailed Description
The technical scheme of the invention is clearly and completely described below with reference to the accompanying drawings and the specific embodiments. The specific matters listed in the following examples are not limited to the technical features necessary for solving the technical problems of the technical solutions described in the claims. Meanwhile, the list is only a part of embodiments of the present invention, but not all embodiments.
According to the flexible production method of the aluminum electrolysis series, the number of the electrolytic cells which are put into production of the aluminum electrolysis series is regulated according to the electricity load, the selling price of the electrolytic aluminum and other market demand conditions, so that flexible production is realized. For example, when the power supply load is intense or the sales price of the product is too low, the production is reduced, and a part of the electrolytic cells are stopped. The method for calculating the number of the slots which need to be stopped when the power supply load is reduced comprises the following steps: the power supply system requires reduced load/load used by each electrolytic cell=the number of electrolytic cells to be stopped, and the number of electrolytic cells to be stopped when the aluminum price is too low is determined according to the specific situation of each enterprise.
In the invention, as shown in figure 1, the electrolytic cells of an aluminum electrolysis series are evenly distributed in two rows of plants which are arranged in parallel, the electrolytic cells are sequentially arranged along the length direction of the plants, and the positions of the electrolytic cells of the two rows of plants are in one-to-one correspondence; in the two rows of plants, one row is an electric inlet side plant 1, and the other row is an electric outlet side plant 2. The aluminum electrolysis series current flows in from the front end of the power-in side factory building 1, flows out from the rear end of the power-in side factory building 1 after sequentially passing through a plurality of power-in side electrolytic tanks 3 arranged, and flows in from the rear end of the power-in side factory building 2 after sequentially passing through a plurality of power-out side electrolytic tanks 4 arranged in the power-out side factory building 2, so as to form a current loop. The electricity inlet end and the electricity outlet end of the aluminum electrolysis series current loop are positioned on the same side of the factory building, as shown by arrows in fig. 1.
The number X of the electrolytic cells needing to be stopped is determined according to the power load or the demand condition. When the cell needs to be stopped, starting from the rear end of the power-in side factory building 1, counting out X/2 electrolytic cells, and connecting the counted electrolytic cells to a power-in side factory building bus. For example, as shown in FIG. 1, each square represents 10 cells. When the cell is required to be stopped at 60 places, 30 electrolytic cells 3 on the power feeding side (3 blocks in the figure) are counted from the rear end (i.e., the current direction end) of the power feeding side plant 1. The power-in side factory building bus 10 is connected at the position, the power-out side factory building bus 11 is connected at the power-out side of the power-out side electrolytic tank 4 corresponding to the power-out side factory building 2, and then the power-in side factory building bus 10 and the power-out side factory building bus 11 are electrically connected through the factory building outer bus 12. The series current forms a new loop from the third regulating bus group 7 formed by the power-in side bus 10, the power-out side bus 11 and the bus 12 outside the plant, so that the power of the following 60 electrolytic cells is cut off.
When the number of the stopping grooves needs to be increased, the newly increased number Y of the stopping grooves is determined, Y/2 electrolytic grooves are counted from the bus of the power-in side workshop close to the power-in end in the power-in side workshop, and the counted electrolytic grooves are connected with the new bus of the power-in side workshop on the power-in side. For example, when the stopping of the cell 80 is still required, as shown in fig. 1, 40 cells 3 (4 blocks in the figure) on the power feeding side are counted from the power feeding side plant bus 10 of the third regulating bus group 7, and a new power feeding side plant bus is connected to the counted cells on the power feeding side. And the corresponding electrolytic cell power-off side of the power-off side factory building is connected with a power-off side factory building bus, and then the power-on side factory building bus and the power-off side factory building bus are electrically connected through a factory building external bus to form a second regulating bus group 6. Similarly, when 60 electrolytic tanks are needed to be stopped again, a first adjusting bus group 5 is arranged.
When the groove is required to be stopped, if two or more sets of adjusting bus groups consisting of the power-in side factory building bus, the power-out side factory building bus and the factory building outer bus are already installed, the adjusting bus group close to the rear end of the power-in side factory building can be removed first and then used for new groove stopping operation. For example, when the third adjusting bus bar set 7 and the second adjusting bus bar set 6 are already provided and the number of stopping slots needs to be increased, the third adjusting bus bar set 7 can be removed first and used as a new first adjusting bus bar set 5 to be installed at a corresponding position so as to reduce the consumption of the device.
When slotting is needed, the operation process is opposite to that of slot stopping. Firstly determining the number Z of slots, starting from a power-in side workshop bus near a power-in end in a power-in side workshop, counting Z/2 electrolytic cells backwards, connecting the power-in side workshop bus at the power-in side of the counted electrolytic cells, connecting the power-out side workshop bus at the power-out side of the corresponding electrolytic cells of the power-out side workshop, and then electrically connecting the power-in side workshop bus with the power-out side workshop bus through the outer workshop bus; after connection, other power-in side factory building buses in the power-in side direction and the factory building external buses and power-out side factory building buses connected with the power-in side factory building buses are removed. For example, in the state shown in fig. 1, if 40 pieces are to be slotted, 20 pieces (2 blocks) are counted from the first regulation bus bar group 5 to the right, and at this position, the first regulation bus bar group 5 is removed after the power-in side plant bus bar, the power-out side plant bus bar, and the power-out side plant bus bar are installed. If 60 slots are to be formed in the state shown in fig. 1, 30 slots are positioned backward at the position where the second adjusting busbar set 6 is positioned. At this time, the existing second adjusting busbar set 6 is regarded as having completed the connection process, and the first adjusting busbar set 5 in the electric-incoming side direction thereof can be removed.
In order to facilitate connection or detachment, the upright post bus bars of the electrolytic tank can be divided into two groups, and the two paths of power-in side factory building bus bars, power-out side factory building bus bars and factory building external bus bars are respectively connected to realize tank stopping.

The first intra-plant connection bus 101 is connected to the second intra-plant connection bus 102 at the corner via a first flexible connection 13. The second intra-plant connection bus 102 and the third intra-plant connection bus 103 are connected in parallel to the outer plant bus 12.
