Abstract
This invention discloses a method for preventing magnetic interference among the vertical cells in an aluminum reduction cell. The method equips a bus bar in each vertical cell that passes through the cell bottom and protrudes from the electrolytic cell gear. The method can incorporate the current from 2-5 cathodic soft bus bars at the back of the reduction cell, directs the current to the cell bottom bus bar, and then directs the current the the cathodic bus bars in the front of the reduction cell. This invention divides the bus bars at the back of the reduction cell and passes some of them through the reduction cell, thus can prevent the magnetic interference from the neighboring vertical cells. This invention has such advantages as simple equipment, and good effect on preventing magnetic interference.
Description
Technical field:
The present invention relates to a kind of method that prevents magneticinterference between the vertical emissions groove of aluminium cell, belong to the aluminium electrolysis slot field perturbation technique field that prevents.
Background technology:
The traditional vertical emissions groove of China's aluminium industry mostly is the self-roasting tank, and in recent years owing to environmental requirement, existing at present production self-roasting tank all is transformed into prebaked cell, and tankage is the comparatively large capacity grooved of 85 ~ 150KA by 55 ~ 70KA reorganization and expansion simultaneously.The groove row spacing of vertical emissions groove is generally about ten meters, distance closer (spacing of present most horizontally-arranged groove is more than 45 meters), and phase mutual interference in magnetic field strengthens between two emissions grooves, has a strong impact on the ordinary production of electrolyzer.Conventional compensation approach adopts bus to be compensated by the big face method of detouring in back more, and its compensation effect can not satisfy the requirement of electrolyzer Magnetic Field Design to jumbo grooved poor effect, can cause electrolyzer stability to wreck, and brings very big harm to production operation.Therefore, existingly prevent that the method for magneticinterference between the vertical emissions groove of aluminium cell from still being not ideal enough.
Summary of the invention:
The objective of the invention is: provide a kind of method that simple, less investment, effect prevent magneticinterference between the vertical emissions groove of aluminium cell preferably that disposes, to overcome the deficiencies in the prior art.
The present invention is achieved in that it all is equipped with the bottom land bus (3) that passes bottom land and pass later from electrolyzer in each electrolyzer of vertical emissions groove, it is after the electric current of per 2～5 cathode soft bus (1) of big face is pooled to the negative busbar (2) of the big face in back after with electrolyzer, again it is compiled electric current and flow into 1 bottom land bus (3), flow into the preceding big face negative busbar (4) of electrolyzer after then the electric current of bottom land bus (3) being walked around electrolyzer, and then the electric current of big face negative busbar (4) before the electrolyzer is entered into the groove riser bus bar (5) of another electrolyzer of downstream; Connect by being weldingly connected respectively between each bus.
Owing to adopted technique scheme, under the voltage condition such as utilization of the present invention, the relation principle that electric current and resistance (bus distance) are inversely proportional to, the big face portion bus in back is passed through electrolyzer in the broken line mode in limited space, with the influence of magnetic field that the adjacent row groove of balance produces, it can prevent the phase mutual interference in magnetic field between the vertical emissions groove of aluminium cell effectively.Adopt the present invention, can not only effectively weaken the influence of adjacent row groove, make that full slot field is evenly distributed, gradient is little, reach the effect of " peak clipping, add paddy ", and can effectively solve the vertical emissions groove magnetic field problem of comparatively large capacity.This busbar arrangement of wearing slot type bottom land bus-bar collocation of the present invention makes electrolyzer obtain rational groove internal magnetic field distribution and stable melt flow field, it can guarantee the stable and higher current efficiency of electrolyzer production process, can well finish design and production demand, fully satisfy the electrolyzer durability requirements.Through evidence, the present invention and the tens of branch couplings of full groove cathode and anode group can reach best electricity, magnetic, the fluid characteristics relation of matching.The present invention has obtained in the preferable groove dynamically electromagnetic hydroimechanics operating performance after test on vertical row's aluminium cells such as 120KA level, 150KA level is used, reached that full slot field is evenly distributed, electrolyzer production is steady.Therefore the present invention compared with prior art, the present invention has that configuration is simple, less investment, result of use is better and the tangible advantage of anti-magnetic field interference effect.

Embodiment:
Embodiments of the invention: the present invention can directly change a social system on existing vertical emissions groove, during making, in each electrolyzer of existing vertical emissions groove, all install the bottom land bus (3) that passes bottom land and pass later from electrolyzer, after the electric current that will have 2～5 cathode soft bus (1) of big face behind the vertical emissions groove electrolyzer now by the bus ways of connecting is pooled to the negative busbar (2) of the big face in back, the electric current that compiles with its negative busbar (2) flow in 1 bottom land bus (3) again, then the electric current of bottom land bus (3) is walked around by the mode of lead and flow into behind the electrolyzer before the electrolyzer in the big face negative busbar (4), and then the electric current of big face negative busbar (4) before the electrolyzer is incorporated in the groove riser bus bar (5) of another electrolyzer of downstream.During making, the connection between each bus preferably adopts the mode of welding to connect.
Claims (2)
1. method that prevents magneticinterference between the vertical emissions groove of aluminium cell, it is characterized in that: it all is equipped with the bottom land bus (3) that passes bottom land and pass later from electrolyzer in each electrolyzer of vertical emissions groove, it is after the electric current of per 2～5 cathode soft bus (1) of big face is pooled to the negative busbar (2) of the big face in back after with electrolyzer, again it is compiled electric current and flow into 1 bottom land bus (3), flow into the preceding big face negative busbar (4) of electrolyzer after then the electric current of bottom land bus (3) being walked around electrolyzer, and then the electric current of big face negative busbar (4) before the electrolyzer is entered into the groove riser bus bar (5) of another electrolyzer of downstream.
