Abstract
The utility model relates to the sealing technology of a horizontal cover of an aluminum electrolysis cell, in particular to a horizontal cover sealplate device for the aluminum electrolysis cell. The horizontal cover flue gas sealing device comprises a horizontal cover sealplate which is arranged at the gap between the horizontal cover of the electrolysis cell and a concave area of an anode guide rod. The horizontal cover flue gas sealing device for the electrolysis cell has the beneficial effects that environmental pollution of a mill plant and surroundings is reduced and the working environment of workers is improved, meanwhile, reclamation of harmful fluoride in the flue gas can be improved, and production cost of primary aluminum liquid can be reduced.
Description
Technical field
The utility model relates to aluminium cell flue gas trapping packing technique, specifically relates to the tightness system in the recessed district of a kind of aluminum cell anode guide rod and level cover contact site gap.
Background technology
The prebaked-anode type cell that certain Chinalco's online production at present moves, be in the high temperature production state more than 950 ℃ since the many decades for a long time, pot superstructure level cover is caused bigger non-reversible deformation, even several kinds of electrolyzers stop groove, overhaul is proofreaied and correct the level cover, but the distortion of level cover still is difficult to restore, the resistance to air loss variation causes electrolyzer to produce a large amount of dissipations of flue gas.Because the singularity of the aluminium cell technological process of production, have to frequently change the anode operation every day, because anode rod distortion, crooked and the craneman of girder steel operates the difference of quality, change in the anodic process at aluminium cell, anode rod or anode girder steel collision level cover become " ordinary affair " that are difficult to avoid, in this replacing anode operation to the collision of level cover, also make electrolyzer level cover that the damaging distortion of hanging low and curling or upwarping bending has taken place, cause the space between anode rod and the level cover gap increasing, the resistance to air loss variation, flue gas trapping efficient is lower.Thereby caused factory building and surrounding enviroment to pollute, the worker laboring environment is poor, and is unfavorable for the recovery of harmful fluorochemical in the flue gas.
Summary of the invention
The technical problems to be solved in the utility model is the deficiency that exists at prior art, a kind of aluminium electrolysis anode guide rod, level cover gap contact site are provided, play the raising resistance to air loss between the slot, strengthen flue gas trapping efficient, reduce the tightness system of harmful fluorochemical discharging in the flue gas.
A kind of aluminium cell level of the utility model cover tightness system, be achieved by following technical proposals: a kind of aluminium cell level of the utility model cover tightness system comprises anode, anode rod, the level cover, level cover sealing plate, anode large bus bar, crust breaking cylinder, the crust breaking hammer stem, gas collection hole, gas skirt, the groove cover plate, three angle cover plates, bassinet stand, stove group, groove thorax sidewall, cathode carbon pieces, cathode steel bar, pot shell, table, level cover gap district, felt, insulating mica plate, described level cover tightness system are arranged on electrolyzer level cover and the recessed gap position, level cover gap district of anode rod.
A kind of aluminium cell level of the utility model cover flue gas tightness system has following beneficial effect compared with prior art: the utility model has improved the electrolyzer sealing property, particularly improve the sealing property of electrolyzer level cover, reached the effect that improves flue gas trapping efficient.By installing and using level cover sealing plate, significantly reduced factory building secondary flue gas concentration, improved the worker laboring environment, for realizing cleaner production and target for energy-saving and emission-reduction, Aluminium Electrolysis takes a firm foundation.The utility model is installed and is formed sealing between level cover " U " type sealing plate and the anode rod at the gap position that electrolyzer level cover contacts with anode rod, plays the effect that seals around the anode rod.Reach the high-seal effect, improve the effect of flue gas trapping efficient.A kind of aluminium cell level of the utility model cover seal plate means has played minimizing factory building and surrounding enviroment and has polluted, and improves worker laboring environment's beneficial effect, has improved the recovery of harmful fluorochemical in the flue gas simultaneously, reduces primary aluminum liquid production cost.

Embodiment
Below in conjunction with drawings and Examples a kind of aluminium cell level of the utility model cover seal plate means technical scheme is further described.
As shown in Figure 1-Figure 3, a kind of aluminium cell level of the utility model cover tightness system comprises anode 1, anode rod 2, level cover 3, level cover sealing plate 4, anode large bus bar 5, crust breaking cylinder 6, crust breaking hammer stem 7, gas collection hole 8, gas skirt 9, groove cover plate 10, three angle cover plates 11, bassinet stand 12, stove group 13, groove thorax sidewall 14, cathode carbon pieces 15, cathode steel bar 16, pot shell 17, table 18, level cover gap district 19, felt 20, insulating mica plate 21, described level cover tightness system are arranged on the recessed gap position, level cover gap district (19) of electrolyzer level cover 3 and anode rod 2.
Described level cover sealing plate 4 adopts the insulating mica plate 21 of thick 10mm to be made by cutting.
Described level cover sealing plate 4 is " recessed " word length square shape, and its profile length of side is 300mm * 250mm; Level cover sealing plate 4 recessed districts i.e. " U " type district are a square, and the length and width size of U-shaped mouth is a bit larger tham anode rod 2 cross sections, and it is of a size of 135mm * 135mm.
Described level cover sealing plate 4 is compound two-layer structure up and down, and the upper strata is an insulating mica plate 21, and lower floor sticks on the thick felt 20 of insulating mica plate downside 10mm.
Before change poles operation in order to prevent that level cover sealing plate from falling in the groove, burnt out by the high-temp liquid ionogen, to in advance level cover sealing plate 4 be moved to be placed on and slit by the district on the level cover of 30～40cm position apart from the anode rod that changes, after groove installs on the new anode, by the gap position of promptly horizontal seal plate 4 buttons being put into anode rod and the recessed district of level cover.At this moment, level cover sealing plate the recessed district of " U " type, just in time form identical mutual snap effect with anode rod, need not fixing in addition or special mounting.In order to play good sealing effectiveness, when the level of installation cover sealing plate 4, a side that must will have felt 20 is installed in the below, is close to the level cover and really plays sealing, prevents that electrolyzer from producing flue gas dissipation, pollutes factory building and surrounding enviroment.
