Abstract
The utility model relates to an anodic structure for improving the discharge rate of electrolytic gas in an aluminum electrolytic cell. The anodic structure comprises an anode assembly and a guide rod assembly, wherein the anode assembly is fixedly connected to the guide rod assembly, the bottom of the anode assembly is provided with a groove, a through hole is formed in the carbon bowl in the middle of the anode assembly, the guide rod assembly comprises a guide rod, a crossbeam and a plurality of steel claws, through holes are formed in two steel claws corresponding to the carbon bowl in a plurality of steel claws and a through hole is also formed in the crossbeam. According to the anodic structure, by virtue of communication of the groove inside the anode with hollow steel claws of the guide rod assembly and adoption of the negative pressure suction effect of the upper part of the groove, the CO2 gas generated at the bottom of the anode in the electrolytic cell is extracted to reduce the occurrence of secondary reactions of dissolved metal aluminum particles with CO2 gas and the improvement on the current efficiency is achieved; by increasing the discharge rate of the electrolytic gas, the overpotential formed by the gas film is decreased and power consumption is reduced; by virtue of the gas discharge heat transfer of the groove in the middle of the anode, the non-conduction time of the new anode is reduced, and thus the fluctuation in the electrolytic cell is reduced; by virtue of the gas discharge heat transfer of the groove in the anode, the gas discharge amount of the machined surface is reduced to be conductive to the downward dissolution of alumina and the operation of the groove is stabilized; and the consumption loss of the fluoride salt flying with gas on the working plane is reduced.
Description
Technical field
The utility model relates to a kind of anode structure of aluminum electrolysis cell, relates in particular to a kind of anode construction that improves aluminium cell water electrolytic gas rate of discharge.
Background technology
In electrolyzer, owing to being subject to the impact of anode top solid electrolyte mulch ventilation property, under mulch, form pressure-fired, anode bottom CO
2gas is difficult to be discharged to upper part of the electrolytic cell space, under melt flow effect, and CO
2the probability that gas enters into electrolyte interface is large, and causes current efficiency low.

2gas is discharged difficulty.
Be subject to CO
2gas is discharged difficult restriction, and anode width size can not increase, and the anode quantity of large-scale aluminum electrolytic cell is too much, and the stability of electrolyzer is poorer.
Utility model content
The utility model for overcome the above problems provide a kind of simple in structure, improve gas rate of discharge, reduce power consumption, improve the anode construction of the raising aluminium cell water electrolytic gas rate of discharge of electrolyzer stability.
The technical solution of the utility model is: this anode construction comprises anode assemblies and guide rod assembly, described anode assemblies is fixedly connected with guide rod assembly, groove is offered in described anode assemblies bottom, in carbon bowl in the middle of anode assemblies, offer through hole, described guide rod assembly comprises guide rod, crossbeam and a plurality of steel pawl, in described a plurality of steel pawls, on two steel pawls of corresponding carbon bowl, offer respectively through hole, on described crossbeam, also offer through hole.
In described groove, be filled with wood chip or bamboo chip, depth of cracking closure 50mm.
The utility model is communicated with by anode interior groove and guide rod assembly Hollow Steel pawl, utilizes the negative pressure-pumping effect of groove top, by the CO generating bottom anode electrolytic cell
2gas is extracted out, reduces the metallic aluminium particle and the CO that dissolve
2gas generation secondary reaction, realizes the raising of current efficiency; By strengthening the rate of discharge of water electrolytic gas, reduce the film formed overpotential of gas, reduce power consumption; Exhaust by groove in the middle of anode is conducted heat, and reduces the non-conductive time of new anode, reduces the fluctuation of electrolyzer; Exhaust by groove in anode is conducted heat, and reduces machined surface free air delivery, is conducive to the downward dissolving of aluminum oxide, gutter operation; Reduce the consumption loss that fluoride salt flies upward with gas at machined surface.
The beneficial effects of the utility model are:
1, improve current efficiency 1.5 ~ 2.5%;
2, reduce the film formed overpotential 10 ~ 50mv of gas and reduce power consumption;
3, reduce the electrolyte melt field of flow fluctuating range in electrolyzer, reduce the erosion pawl of electrolyte melt to steel pawl;
4, be conducive to the downward dissolving of aluminum oxide, machined surface free air delivery reduces, gutter operation;
5, reduce fluoride salt consumption;
6, reduce anode consumption;
7, improve the conduction time of new anode, reduce the fluctuation of electrolyzer;
8, subordinate phase is taped the latent power again: reduce pole span, reduce volts lost.
