SYSTEM FOR LEACHING VALUABLE METALS FROM WASTE DE-NOX CATALYST THROUGH ALKALI FUSION

Document Type and Number:

WIPO Patent Application WO/2020/153779

Kind Code:

A1

Abstract:

The present invention provides a system for leaching valuable metals from a waste de-NOx catalyst through alkali fusion. The system comprises: a supply part including a plurality of hopper tanks for supplying a fixed quantity of waste de-NOx catalysts or alkalis; a transfer part, disposed below the supply part, for mixing and transferring the waste de-NOx catalysts and the alkalis; a fusion part into which a mixture of the waste de-NOx catalysts and the alkalis, transferred through the transfer part, is introduced from one side, and a fusion solution is formed by heating the mixture, an impeller for stirring the fusion solution being provided on one side therein, a cover plate being provided on a surface therein, and the fusion solution being discharged downward through a discharge passage formed inside the cover plate; and a particle generating part including a blow unit, which is disposed below the fusion part to receive the fusion solution, and in which the fusion solution is cooled and particles are simultaneously generated by allowing fluids to flow in at one side while the fusion solution is dropping, a scattering unit which is disposed below the blow unit and which strikes and scatters the dropping particles by tilting a disc rotating at a certain speed, and an inclined plate which is disposed below the scattering unit and which transfers the falling particles among the scattered particles in a certain direction.
