A method and device for removing organic matter in zinc sulfate solution by pressurized atomization

Abstract

The invention relates to a method and a device for removing organic matters in zinc sulphate solution by pressurizing and atomizing, belonging to the field of zinc hydrometallurgy of non-ferrous metallurgy. The method disclosed by the invention comprises the following steps of: adding the zinc sulphate solution into the device for removing the organic matters in the zinc sulphate solution by pressurizing and atomizing after processing by utilizing a pressurizing device and a temperature increasing device, atomizing at first, then, cutting and distributing, finally, strongly stirring, continuously supplying oxygen, ensuring gas cycle of the device, wherein oxygen and the solution in a stirring area are sufficiently reacted so as to realize gas-liquid reaction; oxygen ascends to an atomizing area and is subjected to contact reaction with the atomized solution so as to realize gas-steam reaction; and continuously carrying out circular treatment of the zinc sulphate solution so as to remove the organic matters in the zinc sulphate solution. According to the invention, by means of pressurizing, atomizing and strongly stirring, the organic matters in the zinc sulphate solution are oxidized and decomposed to generate CO2 and H2; the decomposing and removing rates of the organic matters in the zinc sulphate solution are increased; the production cost is reduced; and furthermore, the zinc sulphate solution, the organic matters in which are removed, is steady in quality.

Description

technical field [0001] The invention belongs to the field of nonferrous metallurgy hydrometallurgy zinc, in particular to a method and a device for removing organic matter in zinc sulfate solution by pressurized atomization. Background technique [0002] In the process of hydrometallurgy, too much organic matter in the solution will affect the solution purification and electrolysis production process, resulting in a decrease in electrolysis current efficiency, an increase in DC energy consumption, and an increase in overall production costs. However, the existing method for removing organic matter in zinc sulfate solution needs to add adsorbents or other additives, and the comprehensive recycling of adsorbents or additives is difficult to recover and the overall production cost is high. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides a method for removing organic matter in zinc sulfate solution by pr...
