Abstract
This invention discloses a encircling bus-bar arrangement mode of cannelure, which comprises the following characters: adopting non-isoelectric and four-point electric supply mode, some current of back large face in electrolysis bath issuing along four soft negative busbars, flowing into negative busbars of front large face and into upright busbars of downstream bath, the aftercurrent issuing along nine soft negative busbars and respectively flowing into upright busbars of back large face of downstream bath. Some current of back large face issue along four soft negative busbars, and flow into negative busbars of back large face and into upright busbars of downstream bath. The aftercurrent issue along nine soft negative busbars and respectively flow into upright busbars of front large face of downstream bath along negative busbars. The invention comprises the following merits: reducing effectively the magnetic field in bath and horizontal magnetic field, making the magnetic field in whole bath having the character of adequate distribution, that is, multiple-peaked, low peak-to-trough, solving availably the problem of magnetic field of prebaked bath.
Description
Technical field:
The present invention relates to a kind of aluminum cell bus-bar current arrangements method.
Technical background:
China's aluminium industry has the vertical a large amount of grooveds of emissions groove of production at present now and is 65 ~ 120KA level, because current capacity is less, electric mode is advanced in 2 of many employings on busbar arrangement.Along with the jumbo development of vertical emissions groove, expansion, (grooved of 130KA ~ 150KA current capacity) influences electrolyzer and produces that stable important factor---groove internal magnetic field distribution character (require magnetic field value little, gradient is little) becomes even more important.As adopt original electric mode (2 of terminations are advanced) of advancing, and owing to can not satisfy the requirement of electrolyzer Magnetic Field Design, can cause the electrolyzer local magnetic field excessive, groove stability wrecks, and brings very big harm to production operation.
Along with magnetic field (
) and electric field (
) intensity is big more, its flow velocity is big more and produce the inclination (protuberance) of aluminium liquid and the fluctuation at interface.Therefore advance electricity by multiple spot, reduce the each point current value, make Distribution of Magnetic Field even, increase electrolyzer stability.
Summary of the invention:
The objective of the invention is to: provide a kind of at anode arrangement form and the relevant reasonableness of advancing electric mode, adopt vertical emissions groove circulating type " 4 of different currents advance " bus configuration mode, to overcome the unfavorable factor that jumbo vertical emissions groove exists in the electrolyzer engineering.
The present invention is achieved in that it is to adopt 4 of different currents to advance electric mode, the one part of current of the big face in back in the electrolyzer, flow out by 4 cathode soft bus (1), flow into preceding big face negative busbar again through negative busbar (2) back inflow bottom land bus (3) and enter downstream slot riser bus bar (4), its aftercurrent flows out by 9 cathode soft bus (8), enters big face riser bus bar (5) behind the downstream slot, (6) respectively through negative busbar (9); Preceding big face one part of current, flow out by 4 cathode soft bus (10), flow into the big face negative busbar in back again through negative busbar (11) back inflow bottom land bus (12) and enter downstream slot riser bus bar (6), its aftercurrent flows out by 9 cathode soft bus (13), enters the preceding big face riser bus bar (4) of downstream slot, (7) respectively through negative busbar (14).
Current ratio is 9: 4: 9 between end, front and back and big face 4 root posts: 4.
The present invention compared with prior art has and can effectively reduce groove internal magnetic field and transverse horizontal magnetic field, makes full slot field present multimodal and the lower uniform distribution characteristics of peak valley, has effectively solved advantages such as large-scale pre-baked cell magnetic field problem.The present invention and the tens of branch couplings of full groove cathode and anode group, the best electricity, magnetic, the fluid characteristics relation of matching that reach.Can make large pre-baked cell obtain rational groove internal magnetic field and distribute and stable melt flow field, guarantee the stable and higher current efficiency of electrolyzer production process, can well finish design and production demand, fully satisfy the electrolyzer durability requirements.
Description of drawings:
Accompanying drawing 1 is a principle schematic of the present invention.
Embodiment:
Embodiments of the invention: 15% electric current of the big face in back in the electrolyzer, flow out by 4 cathode soft bus (1), flow into preceding big face negative busbar again through negative busbar (2) back inflow bottom land bus (3) and enter downstream slot riser bus bar (4), its aftercurrent flows out by 9 cathode soft bus (8), enters big face riser bus bar (5) behind the downstream slot, (6) respectively through negative busbar (9); Preceding big face 15% electric current, flow out by 4 cathode soft bus (10), flow into the big face negative busbar in back again through negative busbar (11) back inflow bottom land bus (12) and enter downstream slot riser bus bar (6), its aftercurrent flows out by 9 cathode soft bus (13), enters the preceding big face riser bus bar (4) of downstream slot, (7) respectively through negative busbar (14).Big each section of face negative busbar in front and back and downstream slot riser bus bar are respectively by being weldingly connected.
After the big effusive electric current of face side flows into 4 root post buses by each section bus before and after the electrolyzer, flow on the downstream slot anode large bus bar by 4 root posts, anode rod and anode block flow in the downstream slot groove thorax on the anode large bus bar by hanging over again.
