The invention provides a vanadium extraction leaching device. The vanadium extraction leaching device comprises a tank body, a cover plate arranged at the top of the tank body, a driving motor arranged above the cover plate, stirrers arranged under the cover plate, a plurality of feed inlet nozzles arranged in the cover plate or at the upper part of the side wall of the tank body, sampling nozzles and pH probes arranged in different positions of the side wall of the tank body, a plurality of baffle plates arranged on the inner side wall of the tank body at intervals in the circumferential direction and a feed outlet nozzle arranged at the bottom of the tank body. A stirring rob is arranged under the cover plate. The upper end of the stirring shaft is connected with the driving shaft of the driving motor. The lower end of the stirring shaft is fixedly connected onto the bottom wall of the tank body through a supporting part. The stirrers are arranged on the stirring shaft. The stirrers are arranged in at least two layers in the vertical direction, and the stirring directions of the stirrers of two adjacent layers are different. Through the pH probes and the sampling nozzles arranged in the vanadium extraction leaching device, the on-line monitoring of the whole reaction process can be realized.
Description
technical field [0001] The invention relates to the technical field of hydrometallurgy, in particular to a vanadium extraction and leaching equipment and a vanadium extraction and leaching method using the vanadium extraction and leaching equipment. Background technique [0002] Vanadium is an important metal element with a wide range of uses. About 85%-90% of vanadium is used in steel production. Vanadium is used in steelmaking, which can refine grains and improve the hardness and toughness of steel. Vanadium is also used in catalysts in the sulfuric acid industry and petrochemical industry, in vanadium-titanium alloys for aircraft engines, aerospace cabin frames, ship hydrofoils and introducers, steam turbine blades and rocket engine shells, and for lithium vanadium in high-capacity batteries. Vanadium is used in medicine as an anti-diabetic and a drug for improving cardiovascular function. Even in the ceramic industry and the solar industry, vanadium has a wide range o...
