Abstract
The invention relates to a sealing method of a magnesium electrolysis cell cover. Materials required for the sealing method comprise an asbestos rope (1), a solid NaCl and CaF2 mixture (2), a molten electrolyte (3) and molten asphalt (4). The sealing method comprises the following main steps: firstly filling the asbestos rope (1) into the gaps of the electrolysis cell cover, tamping the asbestos rope (1), then filling the dried solid NaCl and CaF2 mixture (2) at an equal weight ratio into grooves, and then pouring the molten electrolyte (3) into the grooves of the cover; repeating the steps 2-3 times until the materials are solidified; and then pouring the molten asphalt (4) onto the solidified materials. By using the method provided by the invention, the entire electrolysis cell cover can be effectively sealed and the cell temperature and chlorine outlet negative pressure of the electrolysis cell are stabilized, thereby maintaining the normal production of the electrolysis cell and improving the worker working and production environments.
Description
Technical field
The invention belongs to the magnesium eletrolysis technical field, particularly the closing down magnesium electrolysis bath packing technique.
Background technology
The ordinary production of electrolyzer is that the electrolysis of magnesium chloride needs electrolyzer to keep certain temperature, AC starting and direct current can make electrolyzer reach the predetermined production temperature after starting, but if electrolyzer is not effectively sealed, interior air of groove and groove lid outer air are carried out heat exchange must make the groove temperature descend rapidly, also make simultaneously MAGNESIUM METAL oxidation in the groove, influence the negative pressure of tank room again, the chlorine leakage that causes electrolysis production, destroy material balance and energy balance that electrolyzer is produced, the chlorine of Guo Louing must worsen the life security that production environment threatens the electrolysis workman simultaneously.In actual production process, after electrolyzer is adding ionogen and keeping exchanging heated constant temperature 3 days, before sending direct current, need seal to whole electrolytic bath lid to electrolyzer.
Summary of the invention
For solving electrolyzer sealing problem in process of production, the invention provides a kind of sealing method of closing down magnesium electrolysis bath lid, can effectively seal electro bath-lid, prevent that the interior material of electrolyzer and the external world from carrying out heat exchange and exchange of substance.
Technical scheme of the present invention is: a kind of sealing method of closing down magnesium electrolysis bath lid, material requested is mainly by asbestos twine, solid NaCl and CaF
2Mixture, fused electrolyte, molten asphalt are formed, and key step is: at first be filled in the slit of electro bath-lid with asbestos twine, the compacting asbestos twine is again with the solid NaCl and the CaF of mass ratioes such as exsiccant
22 mixtures are filled in the groove, fused electrolyte are poured into groove afterwards again and cover in each groove, repeat to treat for 2～3 times that it solidifies after, pour into a mould molten asphalt more thereon.
Adopt the method for the present invention whole groove lid of sealed electrolytic cell effectively, stablize the groove temperature and the chlorine outlet negative pressure of electrolyzer, thereby keep the ordinary production of whole electrolyzer, improve electrolysis workman work production environment.
Description of drawings
Fig. 1 adopts the resultant sealing ply synoptic diagram of the inventive method.
Among the figure: 1-asbestos twine, 2-solid NaCl and CaF
2Mixture, 3-fused electrolyte, 4-molten asphalt.
Embodiment
Below in conjunction with accompanying drawing sealing method of the present invention is described in further detail.
A kind of sealing method of closing down magnesium electrolysis bath lid, material requested is mainly by asbestos twine 1, solid NaCl and CaF
2Mixture 2, fused electrolyte 3, molten asphalt 4 formed, and its key step is: at first be filled in the slit of electro bath-lid with asbestos twine 1, tamp asbestos twine 1, again with the solid NaCl and the CaF of mass ratioes such as exsiccant
22 mixtures 2 are filled in the groove, fused electrolyte 3 are poured into groove afterwards again and cover in each groove, repeat to treat for 2～3 times that it solidifies after, pour into a mould molten asphalt 4 more thereon.
Claims (1)
