A temperature and liquid level joint adjustment device and magnesium electrolyzer using the device

Abstract

The invention discloses a temperature and liquid level combined adjusting device and a magnesium electrolytic cell applying the same. The temperature and liquid level combined adjusting device is arranged in the magnesium electrolytic cell and comprises a cylinder body which is arranged in a sealed mode; a temperature adjusting cavity and a liquid level adjusting cavity which are independent from each other are arranged in the cylinder body; the liquid level adjusting cavity is located in the temperature adjusting cavity; liquid discharging pipes communicating with the liquid level adjusting cavity and a central cavity are arranged at the lower part of the cylinder body; a connecting pipe communicating with the liquid level adjusting cavity is arranged on the upper part of the cylinder body; gas is injected into or discharged out of the liquid level adjusting cavity through the connecting pipe; electrolytes contained in the liquid level adjusting cavity correspondingly flow from the liquid discharging pipes to the central cavity or flow back; and an air inlet pipe and an exhaust pipe are arranged at the two ends of the cylinder body separately and communicate with the temperature adjusting cavity. The temperature and liquid level combined adjusting device has the advantages that the temperature and liquid level adjusting functions can be combined together through one device, a heat exchanger and a liquid level control device are combined into one, the equipment manufacturing cost can be saved, and the service life is long; and the current efficiency of the electrolytic cell can be improved.

Description

technical field [0001] The invention relates to the technical field of sponge titanium production, in particular to a temperature and liquid level joint adjustment device and a magnesium electrolytic cell using the device. Background technique [0002] In the whole process production process of sponge titanium, the by-product MgCl of sponge titanium is used 2 , using an electrolytic cell to produce metallic magnesium (Mg) and chlorine (Cl 2 ), where Mg can be used for titanium reduction in the return steam system, and Cl 2 Sent to chlorination system to produce TiCl 4 . [0003] Magnesium electrolysis is one of the key links in the whole production process of sponge titanium. The electrolytic cell is the core equipment of the magnesium electrolytic process. The temperature control of the electrolytic cell is very important, because the temperature of electrolysis affects the conductivity, primary crystal temperature, density, and Physical and chemical properties such as ...
