After the material is applied to the electrolysis cell, the heat loss of the side part can be greatly reduced, the electricity energy utilization rate is improved, and the electricity consumption per ton of aluminum is reduced.
Description
Technical field
The utility model belongs to the aluminum electrolysis field, relates in particular to a kind of aluminum electrolyzing cell used side lining.
Background technology
Large-scale aluminum electrolytic cell design has been adopted between the good silicon nitride combined silicon carbide brick of single circle strip, sidepiece welding finned heatsink, heat conduction, groove and the heat dissipation technology of the plenum of factory building etc.This kind design causes the utilization ratio of electrolysis electric energy low (less than 50%), and the heat radiation on electrolyzer sidepiece and top is the major cause of energy loss, and wherein the sidepiece heat radiation can account for the 30%-45% of the total heat dissipation capacity of whole electrolyzer.
In order to reduce the aluminium cell power consumption, current numerous electrolysis plants are extensively carried out low bath voltage production run, need to reduce the cell body heat energy dissipation, the insulation of intensified electrolysis groove, the insulation of lay special stress on sidepiece.
Existing aluminum electrolyzing cell used side lining mainly contains three kinds of forms, and the one, common charcoal piece, the 2nd, silicon nitride combined silicon carbide brick, the 3rd, the composite block of silicon nitride combined silicon carbide brick and common charcoal piece.Common charcoal piece heat-insulating property is better, but the potential resistance to electrolyte contamination corrosive power is poor, be prone to oxidation.Silicon nitride combined silicon carbide brick electrolyte-resistant erosional competency is strong, but insulated capacity is poor, and the sidepiece heat radiation is big; Price is high simultaneously, and the common charcoal piece of separate unit cost exceeds more than 1 times.The composite block of silicon nitride combined silicon carbide brick and common charcoal piece has been gathered the advantage of two kinds of materials, and the more common charcoal piece of price is high, and heat radiation is greater than common lateral mass.
The utility model content
The purpose of the utility model is the deficiency that exists to above-mentioned prior art, and a kind of aluminum electrolyzing cell used side lining is provided, and the heat that the electrolyzer of using this material can reduce sidepiece scatters and disappears, and improves utilization rate of electrical, reduces a ton aluminium power consumption.
Above-mentioned purpose realizes through following proposal:
A kind of aluminum electrolyzing cell used side lining is characterized in that, said liner is the composite block of silicon nitride combined silicon carbide brick and refractory brick, or the composite block of common charcoal piece and refractory brick.
A kind of aluminum electrolyzing cell used side lining of the utility model is characterized in that, the composite block of the composite block of said silicon nitride combined silicon carbide brick and refractory brick, common charcoal piece and refractory brick adopts JM2600 Blakite JM3300 bonding.
A kind of aluminum electrolyzing cell used side lining of the utility model is characterized in that, said silicon nitride combined silicon carbide brick or the big face of common charcoal piece are offered groove, and said groove is embedded in said refractory brick.
A kind of aluminum electrolyzing cell used side lining of the utility model is characterized in that, said groove is unidirectionally to open, two-wayly open or seal.
A kind of aluminum electrolyzing cell used side lining of the utility model is characterized in that, the area that said silicon nitride combined silicon carbide brick or big of common charcoal piece are attend institute's recessing is 40%～80% of an original area.
A kind of aluminum electrolyzing cell used side lining of the utility model is characterized in that, the said silicon nitride combined silicon carbide brick or big institute of the common charcoal piece recessing degree of depth are 30%～60% of original thickness.
The beneficial effect of the utility model: the heat that the electrolyzer of the liner of application the utility model can significantly reduce sidepiece scatters and disappears, and improves utilization rate of electrical, reduces a ton aluminium power consumption.
