Multipolar Magnesium Electrolysis Technology In Titanium Sponge Productionresearch And Analysis Of The Feasibility Of The Application

In recent years,rapid development of titanium sponge industry in China,but with Japan,the United States,Russia and other countries there is a big gap.The gap is mainly domestic sponge titanium enterprises mostly only reduction process.The by-product magnesium chloride can only be cheap export or industrial waste,harm environment.Therefore,the titanium sponge titanium enterprise through improving the magnesium electrolysis process,so that the production system to form a cdosed circuit production mode,realize the recycling of magnesium and chlorine,has become the inevitable direction of development.In our country the first matched with the sponge titanium production is no clapboard magnesium electrolytic cell,the process while achieving the recycling of magnesium and chlorine,but by the time magnesium electrolysis technology development limited,sponge titanium production is mainly with Alcan without clapboard magnesium electrolysis process matching,the concentration of chlorine production only about 70%,output of liquid magnesium need refining it may use,huge environmental hazard,reducing the effect is not obvious.With the continuous development of magnesium electrolysis process,as well as the people of process environment friendly,and energy saving and emission reduction requirements more and more high,without clapboard magnesium electrolyze and titanium sponge production matching disadvantage is becoming more and more obvious.The main advantages of multipolar magnesium electrolytic cell technology is the high concentration of chlorine gas,directly out of high purity magnesium,DC power consumption is low,the current efficiency is good,is now the world’s most advanced magnesium electrolysis process,was also known as the current and the titanium sponge production supporting special preparation of magnesium technology.This paper for multipolar magnesium electrolysis technology for in-depth study,and the comparative analysis was performed according to the effect of three companies multistage magnesium electrolysis process used in the production of sponge titanium,draws the multipolar magnesium electrolysis technology was widely promote a mature technology,and titanium sponge production closely matching,science,its technical indicators far outperforms the traditional baffle slot and multipolar magnesium electrolysis system can matched with the titanium sponge production system chlorination process and reduction process,to achieve recycling magnesium chlorine,these two kinds of titanium sponge production main cost factor,dramatically reducing production costs,and solve the chloride magnesium pollution of groundwater,chlorine free emissions and other environmental hazards.Through of Fushun Titanium Industry Co.,Ltd.of magnesium reduction project implementation scheme demonstrates,the implementation of the project the best place selection,process route selection,selection of main process equipment and supporting facilities,and the scheme of the environmental impact analysis conclusion and economic analysis conclusion.The successful application of this technology will greatly promote China sponge titanium industry to industry development,the application of the technology is that quality and high-grade products,technology and equipment of large-scale both sponge titanium industry development trend,another important development direction,it will for the current downturn in the sponge titanium industry bring glimmers of hope.
