Description
Technical field
The utility model relates to a kind of reactor, especially relates to a kind of noble metal close dissolving reactor.
Background technology
Noble metal comprises gold, silver and platinum, palladium, rhodium, iridium, osmium, eight elements of ruthenium, wherein platinum, palladium, rhodium, iridium, osmium, six elements of ruthenium are called again platinum group metal, due to the uniqueness of its performance and the scarcity of resource, be used as " strategic reserves metal " in the world.The preparation of the extraction of noble metal, separation, refining and precious metal chemical complex all needs it is dissolved, so the reaction vessel that noble metal dissolves is particularly important.
Because platinum group metal is electropositive metal, except the very strong fine-powdered metal of chemical reactivity can slowly be dissolved in red fuming nitric acid (RFNA) and the concentrated sulfuric acid, other platinum group metal is insoluble to any single inorganic acid, must in acid solution, add strong oxidizer, make oxidizing potential surpass the electrode potential of platinum group metal, just can capture electronics platinum group metal is oxidized to from entering solution.
Gold in noble metal, platinum, three elements of palladium belong to soluble element, and rhodium, iridium, ruthenium belong to indissoluble solution element.Easily soluble noble metal hydrometallurgical technology commonly used leaches from waste material, its main method has 1, aqua regia dissolution: this is the classical way of noble metal waste material, because technology is reliable, yield is high, the short dissolving that is widely used in large noble metal waste material and high-load noble metal waste material of cycle; 2, sulfuric acid or nitric acid dissolve: sulfuric acid or nitric acid can with the palladium effect, generate the sulfate and nitrate of solubility; 3, aqueous solution chlorination dissolves: the aqueous solution chlorination method refers to logical chlorine in water and HCl solution medium, by chlorination, makes noble metal in raw material with the stripping of chloride form.The aqueous solution chlorination method is one of leaching means the most frequently used in precious metal hydrometallurgy, by this method, processes various dead catalyst, and metal leaching rate is higher, general all more than 98%.
Summary of the invention
The utility model, for gold, platinum, three soluble elements of palladium, provides a kind of noble metal close dissolving reactor, has effectively solved the loss of noble metal in noble metal close dissolving process and the problem of Environmental security.
For achieving the above object, the technical solution that the utility model adopts is:
Noble metal close dissolving reactor, comprise still body, kettle cover and support, and still is as upright cylindric and vertically rack-mount, and still body outside is surrounded by heating jacket, and a discharge gate is arranged at bottom, and blow-off valve is arranged on discharge gate; Solution feed mouth, condensing reflux mouth, solid material charging aperture, vacuum degassing mouth, temperature-measuring port and agitator are arranged on kettle cover, high-level container and condensing reflux pipe are vertically rack-mount, the solution feed mouth connects inlet valve and high-level container, the condensing reflux mouth is connected with the condensing reflux pipe, on the solid material charging aperture, blind flange is arranged, the vacuum degassing mouth has vacuum valve; Still body and kettle cover connect into an integral body by jockey.
During work, first by negative pressure, acid solution is extracted in high-level container, opens inlet valve the acid solution in high-level container is slowly put into to reactor, open blind flange and add materials at the solid packing mouth, heating jacket is heated, and turn on agitator is stirred.Vacuumize from the vacuum degassing mouth in course of reaction, prevent that reaction from producing too high pressure, causes potential safety hazard; Temperature when temperature-measuring port records reaction, controlled heating jacket, thus the temperature while controlling reaction; The steam produced during reaction returns in reactor after the condensing reflux pipe is cooling.Stop after having reacted stirring and the heating jacket heating, open blow-off valve after cooling to discharge material, the cleaning tank body is gone forward side by side into subsequent processing.
