Abstract
The invention discloses a cathode bus bar wire structure of 350KA aluminum electro-bath that adopts the method of large face six pointers input electricity, and 6 column bus bar wires are set at the electricity inputting side. The electricity input side bus bar wire and the electricity output side bus bar wire adopt multilayer bus bar wire symmetrically collocation. The bus bar wire beside the electro-bath adopts stair collocation. And the compensation bus bar wire under the bottom of electro-bath adopts the collocation method of lower than the AB girder of the groove to pass through the bottom. The cathode bus bar wire and the cathode steel stick adopt cathode steel stick compressor to join together. Others adopt common location and connection. The invention successfully solves the problem of equality and stability of the melting magnetism in the large aluminum electro-bath.
Description
Technical field:
The present invention relates to a kind of negative busbar collocation method that is used for super-huge prebaked cell.
Technical background:
Along with improving constantly of aluminium cell designing technique and process operation level, the working current of modern large-scale aluminum electrolytic cell increases just day by day, and the magnetic field that its current carrying bus and melt electric current produce more shows outstanding to the production of electrolyzer and the influence of steady running.Because the electromagnetic force that magnetic field and melt Interaction Law of Electric Current produce makes in the groove melt circulation quicken, and causes liquid aluminum generation protuberance, deflection and fluctuation, in addition may influence electrolyzer can not ordinary production.Therefore, during a dynamical large scale electrolytic cell, must consider to weaken and the control flume internal magnetic field, its magnetic-field component value is dropped in the numerical range of qualification, thereby obtain stable, production effect efficiently by rational busbar arrangement in design.
Summary of the invention:
The objective of the invention is to: the novel bus collocation method that a kind of 350KA of being applicable to electrolyzer is provided, make it under the big strength of current of 350KA, the magnetic field of melt is distributed rationally, is stablized in the electrolyzer, the electric current distributed uniform, guaranteeing stable, the ordinary production of electrolyzer, and for improving current efficiency, reducing power consumption and create conditions.
The present invention is achieved in that the mode that adopts 6 in big face to advance electricity, electricity input side has 6 root post buses (1), electricity input side bus (2) adopts the balanced configuration of multilayer bus with electricity output side bus (5), the groove side bus (3) at electrolyzer two ends adopts the staged configuration, compensation bus (4) at the bottom of the electrolytic bath adopts and is lower than groove AB beam and wears the mode of bottom land and dispose, adopt cathode steel bar connector presser (7) to connect between cathode soft bus (6) and the cathode steel bar (8), other be routine layout be connected.
In above-described formation, the current ratio distribution means of 6 root post buses (1) of electricity input side for equating, electricity output side bus (5) adopts the frame mode around negative busbar.
The configuration structure characteristics of this bus are: advance a side bus (2) and adopt balanced configuration with electricity output side bus (5), guaranteed the homogeneity of groove internal magnetic field, and in electricity output side bus (5), the electricity output side cathodic current is divided into 6 groups, all adopt mode, with the distribution of current of balance AB side around negative busbar.At the influence of big galvanic series adjacent row slot, groove side bus (3) is taked the staged configuration, offsets the reverse influence of electrolyzer AB side vertical magnetic field simultaneously.Bottom land compensation bus (4) adopts and is lower than the collocation form of wearing bottom land of electrolyzer AB beam, thereby greatly reduces electrolyzer vertical magnetic field gradient in the horizontal direction.Riser bus bar (1) adopts 6 geometric ratios of big face to advance the frame mode of electricity.Consider the welding difficulty of electrolytic cell overhaul, adopt cathode steel bar connector presser (7) to connect between cathode soft bus (6) and the cathode steel bar (8).
During work, galvanic current enters the 6 root post buses (1) of this groove from the upstream electrolyzer, electric current enters on the anode large bus bar of groove superstructure by riser bus bar, be redistributed to and respectively organize anode, flow through melt dielectric substrate, aluminium liquid layer in the groove, and behind the cathode carbon pieces, cathode steel bar, by being connected in the cathode steel bar connector presser (7) between cathode steel bar (8) and the cathode soft bus (6), the cathode soft bus of A side imports electricity input side bus (2) with electric current, the B side then import to electricity output side bus (5).The electric current of electricity input side bus (2) enters on the 6 root post buses of downstream slot by groove side bus (3) and 6 bottom land compensation buses (4) at electrolyzer both ends respectively, and the electric current of electricity output side bus (5) then directly imports the riser bus bar of downstream slot.Wherein the electric current of electricity input side about 60% enters downstream slot by the groove side bus (3) at two ends, and about 40% electric current enters downstream slot by the compensation bus (4) of bottom land.
The invention has the beneficial effects as follows: it has successfully solved the homogeneity of melt magnetic environment in the super-huge aluminium electrolysis cell, the problem of stationarity, thereby makes that groove internal magnetic field gradient is littler, for electrolyzer is enhanced productivity, steady running is laid a good foundation.
