The device favorably improves the whole thermal insulation properties of the aluminium electrolytic tank, and also reduces the diffusing capacity of flue gas produced in the aluminium electrolytic tank around factories, so that the heat dissipation loss of the upper part of the aluminium electrolytic tank can be greatly reduced, heat balance when a low voltage is normally operated is maintained, and the thermal insulation requirement of a future low temperature aluminium electrolytic tank is met.
Description
Technical field
The present invention relates to a kind of Upper part seal structure of aluminium electrolytic tank.
Background technology
The trend of aluminum electrolyzation technology development in the present age develops towards the technique direction of " low pole span, high-density, low power consumption and low emission ".Research and development heat preservation aluminum electrolyzer, reduces electrolyzer thermosteresis, realizes the development trend that aluminium cell stable and high effective operation under low voltage, high pole span is the outer aluminium industry of Present Domestic
[1].Because inert anode fails to apply on a large scale produce, common carbon anode also could not be substituted, and aluminium cell must maintain it by periodic change poles and normally run
[2].Aluminium cell operationally, has gas to generate under anode bottom, and gas and the anode bottom of generation participate in chemical reaction, cause anode constantly to be consumed, and the minimum consumption of theory often producing an aluminum anode is 333kg
[3].Aluminium cell is when change poles, and electrolyte melt directly contacts with the air of surrounding environment with surface coating, causes the heat dissipation capacity of electrolyzer sharply to increase, and can break the original thermal equilibrium system of trough in a short time.When particularly change poles occurs in four bights of electrolyzer, can cause around stove side thicken, stretch one's legs elongated.Stretch one's legs the elongated increase that can cause again aluminium liquid layer horizontal current, current efficiency declines.By calculating, the top heat radiation of aluminium cell accounts for more than 60% of total heat dissipation capacity
[2], so the top insulation strengthening aluminium cell seems particularly important.Predictably, the insulation construction of following aluminium cell and material all will make certain change, to meet the power conservation requirement of low-temperature aluminum electrolysis.
