Description
Technical field
The utility model relates to a kind of cooling system, relates in particular to a kind of pressure cooling system of aluminium cell.
Background technology
With in the process of Hall-Ai Lutefa electrolytic production of aluminum, make aluminium liquid and electrolyte melt temperature approximately be stabilized in 950 ℃ by joule effect, heat scatters and disappears away by liner and coating material layer again, and then makes whole cell body be in thermal equilibrium state.
And along with the continuous increase of reinforcing current by aluminum electrolytic cell, keeping under the constant prerequisite of original processing condition and production system, the heat flow rate per unit area of its cathode groove shell also increases thereupon, this will cause the attenuate of ledge thickness, the rising of shell temperature and the distortion of outside steel plate, thereby influences current efficiency, ton aluminium energy consumption, stability and the cell life of electrolyzer.Therefore, in the design process of large-scale aluminum electrolytic cell, must correspondingly take cooling measure effectively, improve the heat-sinking capability of electrolyzer, keep the thermostability of electrolyzer.
USSR (Union of Soviet Socialist Republics) utility model patent Nos.SU 605 865 and SU 663 760 disclose the cooling system that a cover can be controlled outside electrolyzer have been installed.The groove sidepiece of this kind electrolyzer comprises airtight hole, variable insulation board and fan, and wherein fan is equipped under the electrolyzer, and by adjustable valve control.The cooling air that fan is discharged is provided by gas blower or compressor.But the Infrastructure that these equipment claimed are very huge and heavy.

Domatic in order to help to form curing electrolysis melt, U.S. Pat 4 087 345 proposes to install a kind of casing of being furnished with stiffening web and reinforcing skeleton on cell body, help the side by the natural convection cool electrolysis cells of ambient air.But these static devices are not suitable for accurately controlling heat flux.
In order to control the heat of solidifying the domatic formation of electrolysis melt and recovering to take away from trough side part, U.S. Pat 4 608 135 proposes pipelining between the internal insulation of margin plate and cell body, in establish gas extractor, and air inlet port is arranged on the groove sidepiece.Gas extractor is carried by pipeline it from the peripheral air that sucks of trough side part along margin plate.Though this complete equipment is the cooling tank sidepiece effectively, need do bigger change to electrolyzer, and can not make the electrolyzer isolated operation.
June 26 calendar year 2001, a kind of by non-tight type refrigerating unit around pot shell air blast cool electrolysis cells by patent US 6 251 237B1 (corresponding to the FR 2 777 574) proposition of Pechiney company application.But this method is gone into potroom with a large amount of hot blows, and groove temperature is on every side risen, and has worsened the operating environment in the potroom.
On September 7th, 2005, the patent CN 1665963A (corresponding to the US 20060118410A1 on June 8th, 2006) that is applied for by Pechiney company has proposed another kind of method of cooling.To seal corresponding to the outside pot shell of the electrolyzer in melt zone, and offer two inlets, a nozzle blasts air, and another then is refrigerant, for example distilled water.With the refrigerant atomizing, make it to form convective heat exchange with the pot shell surface, by the heat radiation that the latent heat of vaporization is stored pot shell, by forced air flow it is taken away at last.Simultaneously, this patent has also been developed the complete circulating cooling system of a cover for this reason, with refrigerant condensation recycling.This closed system has higher cooling efficiency, but electrolyzer is too strong to the dependency of this system, just can not stop once operation; And this cooling system structure is complicated, and has additionally added equipment such as condenser, atomisation unit, has increased running cost.
At the heat dissipation problem of aluminum cell side, all there is certain defective in such scheme.So the applicant is intended to propose a kind of simple and low-cost apparatus.
