Device for heat exchange of electrolytic bath

Abstract

The invention relates to a device for heat exchange of an electrolytic bath, which comprises an air inlet tube, an air outlet tube, stainless steel sleeves and a cooling coil. A heat exchanger is perpendicularly mounted below a cover of a magnesium collection compartment of the electrolytic bath and integrated with the cover of the electrolytic bath. The air inlet tube and the air outlet tube are respectively connected with the cover. The cooling coil is in a multi-set structure and subjected to temperature resistance and corrosion resistance treatment. The outer sleeves for the air inlet tube and the air outlet tube between the level of electrolyte and the bottom of the cover are made of anticorrosion or stainless steel materials, and castables are cast between each stainless steel sleeve and the corresponding one of the air inlet tube and the air outlet tube. Safe and reliable temperature regulation and control for the electrolytic bath are realized by the heat exchanger physically, damage of mass balance, chemical balance and thermal balance of the electrolyte in the electrolytic bath can be reduced, operation is facilitated, operation safety of the electrolytic process is ensured, current efficiency of the electrolytic bath is improved, product quality and mass are improved, operation stability of the electrolytic bath is guaranteed effectively, and energy consumption of an electrolytic system is reduced.

Description

[0001] The invention relates to a technology in the field of metal magnesium smelting equipment, in particular to a device for heat exchange in an electrolytic cell. Background technique [0002] In the entire production process of sponge titanium, the by-product MgCl of sponge titanium is used 2 Use electrolyzer to produce metal magnesium and chlorine, of which Mg is used in the steaming system for titanium reduction, and Cl 2 Sent to chlorination system to produce TiCl 4 . [0003] Magnesium electrolysis is one of the key links in the entire production process of sponge titanium. The electrolytic cell is the core equipment of the magnesium electrolysis process. The temperature control of the electrolytic cell is very important because the temperature of the electrolysis not only affects the conductivity, primary crystal temperature and density of the molten electrolyte. Physicochemical properties such as, viscosity, surface tension, etc., and directly affect the current efficiency...
