Embodiment Construction
[0025] The technical solutions of the present invention will be further described below in conjunction with the drawings and specific implementations.
[0026] This embodiment discloses a wet reactor for improving the efficiency of vanadium dissolution-deammonium and ammonium transformation reaction and a reaction method based on the wet reactor. Such as figure 1 As shown, the wet process reactor includes a reactor 1, and a foam collection chamber 2, an impeller assembly 3, and an exhaust port 4 are sequentially arranged on the top of the reactor 1 upwards. On the top of the foam collection chamber 2 and located at the top of the impeller assembly 3. An inner flow guiding tube 51 and a flow guiding outer tube 52 are provided on the outside, wherein the vertical flow guiding inner tube 51 serves as the suction port of the upper structure. The height of the inner diversion tube 51 is smaller than the height of the outer diversion tube 52. A cleaning hole 8 and a motor 7 are arrange...

The invention discloses a wet-process reactor and a reaction method, and belongs to the technical field of hydrometallurgy, and the wet-process reactor and the reaction method are designed for solvingthe problem that negative influence on quality and purity of late-stage products can be generated in an existing defoaming method. The wet-process reactor comprises a reaction kettle, wherein the topof the reaction kettle is provided with a foam collecting chamber, an impeller assembly and an air outlet; a flow guide inner tube and a flow guide outer tube which are arranged in a sleeve mode arearranged at the top of the foam collecting chamber; a capturing chamber is formed between the flow guide inner tube and the flow guide outer tube, and the capturing chamber communicates with the foamcollecting chamber through a backflow pipe; an expansion chamber is formed at the top of the capturing chamber; and a press-down turbine impeller and a six-straight-blade disc turbine are arranged inthe reaction kettle. According to the wet-process reactor and the reaction method, bubbles generated in a reaction process can be sheared and crushing into smaller bubbles which are easy to capture, so that reaction efficiency is improved, liquid and solid reactants are mixed more sufficiently, operation is simpler, no pollution is caused, adverse effects on product quality and purity is not generated, and reaction efficiency is higher.
Description
Technical field [0001] The present invention relates to the technical field of hydrometallurgy, in particular to a wet process reactor for improving the efficiency of vanadium dissolution-deammonium and ammonium transformation reaction and a wet process reactor for improving vanadium dissolution-deammonium and ammonium The reaction method of chemical transformation reaction efficiency. Background technique [0002] Hydrometallurgy is a process of chemical treatment or organic solvent extraction of metal mineral raw materials in an aqueous solution of acid or alkaline medium, separation of impurities, and extraction of metals and their compounds. At present, most vanadium minerals are decomposed, extracted and dissolved vanadium- Hydrometallurgical processes are used for the removal of ammonium, ammonium transformation and impurity removal. [0003] In the hydrometallurgical process, there are problems that the leaching rate of P impurity elements is high and a large number of bubb...
