Abstract

The invention provides a recovery device for valuable metals in waste foamed nickel, and is suitable for the field of heavy metal recovery. The recovery device comprises a material barrel, a pure water inlet, a sodium chlorate solution inlet, a dilute sulfuric acid inlet, a feeding port and a safety valve are formed in the top of the material barrel, a material stirring barrel is arranged inside the material barrel, and a collecting box is arranged below the material barrel. According to the recovery device, the material stirring barrel is partitioned, continuous oxidation acid leaching operation can be carried out, the reaction time is greatly shortened, the reaction efficiency is improved, the leaching rate of metal is obviously improved, the nickel leaching rate can reach 99% or above,the treatment effect is obvious, in addition, an online monitoring system is introduced for flammable and explosive hydrogen gas, it is guaranteed that the reaction can be conducted safely and continuously, the reaction safety coefficient is improved, and the possibility of accident occurring is reduced.

Description

technical field [0001] The invention belongs to the field of heavy metal recovery, in particular to a recovery device for valuable metals in waste nickel foam. Background technique [0002] Nickel foam is a sound-absorbing material with excellent performance. It has a high sound absorption coefficient at high frequencies. The design of the sound-absorbing structure can improve its sound-absorbing performance at low frequencies. Nickel foam is also used to manufacture cadmium-nickel batteries and hydrogen-nickel batteries. One of the best electrode materials for nickel batteries. [0003] The matrix material used for the foamed nickel electrode material is a porous open-cell foam plastic, which contains spongy porous metal nickel, iron, copper and their composite layer porous body. At present, the commonly used method is to use wet extraction. Hydrogen is easily generated during the process, and the reaction is violent at the same time, which is not conducive to safe product...
