Embodiment Construction

[0014] The solution of the present invention will be described in further detail below in conjunction with the examples, but this description will not constitute a limitation of the present invention.

[0015] Such as figure 1 As shown, an electrolytic cell for electrolytic manganese production comprises eleven unit electrolytic cells, an ion diaphragm 1 and a sealing gasket are arranged between each of the unit electrolytic cells, and the ion diaphragm is a highly conductive acid and alkali resistant Polyvinyl fluoride-based or polysulfone-based homogeneous anion-exchange membrane; the interior of the unit electrolyzer is alternately arranged with mesh anodes 2 and plate-shaped cathodes 3, which are called anode chamber 8 and cathode chamber 9 respectively. , the mesh anode is a three-dimensional mesh coating anode composed of two or more mesh coating anodes connected in parallel, and the mesh coating anode is titanium-based, aluminum-based, copper-based or nickel-based Ruth...

Abstract

The invention relates to an electrolytic tank for electrolytic manganese production, in particular to an electrolytic tank adopting an anion-exchange membrane and a titanium-based coating anode. The electrolytic tank comprises a plurality of unit electrolytic tank bodies, and an ion diaphragm and a sealing gasket are arranged between every two unit electrolytic tank bodies. The electrolytic tank has the advantages that due to ion selective permeability of the anion-exchange membrane, manganese ions are limited in a cathode chamber, in this way, only deposition of manganese on a cathode occurs in the electrolytic process, and anode mud cannot be generated; 2, due to the fact that a great amount of anode mud is not generated any more, the electrolytic tank does not need to be cleaned frequently, and production efficiency can be greatly improved; 3, a reticular titanium-based coating is adopted to form a three-dimensional electrode to serve as the anode, and the reticular titanium-based coating has a large reaction area and low oxygen evolution potential, so that the electrolytic tank formed in the mode is 0.5-1 V lower than traditional tank pressure, and electrolytic energy consumption can be lowered by 20% and above.

Description

technical field [0001] The invention relates to an electrolytic cell for electrolytic manganese production, in particular to an electrolytic cell using an anion exchange membrane and a titanium-based coating anode. Background technique [0002] In the industrial production of electrolytic manganese, the electrolytic cell has been composed of cloth bag diaphragm and grid anode made of lead alloy, such as patent: 200820054326.2 (energy-saving electrolytic manganese device). And a lot of improvements have been made to the anode structure, such as patent: 201310575496 (an electrolytic manganese anode plate and its manufacturing method); in order to save energy and reduce consumption, optimize the distance between the cathode and anode as much as possible, and the pole distance of the same name of the electrolytic cell has been reduced to 650-700mm. However, since the bag-type diaphragm only has a partial physical barrier effect, it is impossible to avoid the diffusion of mangan...
