Abstract
A system and method is provided for control of layer formation by use of sidelining provided with heat tube.
Description
Background of invention
Background technology
Now, produce in the process of aluminium at the electrolysis tech that relies on so-called aluminium cell (Hall-H é roult cell), the operation of electrolytic cell relies on the protective layer that forms and keep solidifying electrolyte on the cell sidewall.This solidification liquid (frozen bath) is called as the side layer and protects the sidelining of electrolytic cell to avoid chemistry and mechanical wear, and this solidification liquid is to realize the long-life necessary condition of electrolytic cell.Crystal solution (crystallized bath) is used as the buffer of electrolytic cell changes in thermal balance simultaneously.In operation, the heat of electrolytic cell produces and thermal balance will be owing to undesirable interference (variation of the variation of liquid acidity, the variation of alumina concentration, anode-cathode distance of operation, etc.) and electrolytic cell on required activity (metal slag tap variation, the roasting (fire) of (metal tapping), anode, etc.) change.This will cause the thickness of the layer of electrolysis bath circumference to change, and in some cases, the layer of a part on every side is with complete obiteration.Then, sidelining will be exposed to electrolyte and metal, and this combines with the effect of oxidizing gas and will cause the sidelining material corrosion, cause the sidelining corrosion.In operating process, along with the time, the generation repeatedly of this situation will cause the sidelining full consumption.Therefore, the stability of the formation of key-course and layer is very important in aluminium cell.For the aluminium cell with high current density, model calculates and shows, since bigger caloric value, the very difficult side layer that keeps electrolytic cell.Therefore, concerning this electrolytic cell and traditional electrolytic cell with thermal balance question, can keep protecting the layer of sidelining will be the long-life condition of electrolytic cell.
Producing according to the aluminium cell principle in the process of aluminium, energy use at present is higher, need be with the energy of kilowatt hour metering as producing per kilogram aluminium.It is the result that ohm voltage (ohmic voltage) descends in the electrolytic cell that the heat of electrolytic cell produces, and ohm voltage that for example takes place in the metal of current feed, production and particularly electrolyte descends.The heat that about 55% of the energy of input electrolytic cell is used for electrolytic cell produces.The data of document show about 40% the running off by sidelining of net quantity of heat loss of electrolytic cell.Because the loss of the high heat of sidelining and protection solidification layer, sidelining are the optimum positions that heat regeneration element is set in this zone of electrolytic cell.
There is a kind of expectation of regenerating with heat that forms for the optimal control layer.In order to optimize this two purposes simultaneously, the side layer that heat regeneration is positioned as close to formation is very important.This control and layer speed that forms that will cause layer to form is fast as far as possible, and the temperature difference between the cooling medium of the cooling medium of input and output is big as far as possible.The latter is preferred to the utilization/regeneration of energy.
In the prior art, can be with reference to the granted patent of NO 318012, this granted patent enters the PCT stage as PCT/NO2004/000070.This patent documentation has been described a kind of sidelining, and this sidelining is formed with the hole of flowing through for cooling medium (hollow).But, the manufacturing process complexity of this sidelining, and need before the material sintering, be preferably formed molded porose sidelining.
Usually, problem is that heat transmission needs little and thin passage (canal) efficiently, and still, this passage is difficult to make in reliable mode, and can be blocked in sintering process.
In addition, can wherein describe a kind of aluminium cell with reference to GB2076428A, have separation layer on the bottom of this aluminium cell and the wall.Wall is provided with charcoal piece (carbon block), is molded with heat pipe in this charcoal piece, so that heat is removed from electrolytic cell.This heat pipe can be adjusted into different distances to change the degree of heat extraction.
Heat pipe enters in the hole that drills through in the sidelining material, and the problem that this heat pipe is set is, the difference between heat pipe and the sidelining material coefficient of thermal expansion coefficient will cause forming crack or heat pipe and lose with sidelining and contact in sidelining.Also there is significant temperature difference in hole in sidelining.
Therefore, need a kind of method and system that overcomes the problems referred to above.
