Problems solved by technology

However, before the pure metal is separated by electrowinning, the cyclone electrowinning technology still needs to dissolve the metal waste in acid to prepare a metal salt solution, which consumes a lot of acid and causes certain environmental pollution.

Abstract

The invention relates to a rotational flow electrolyzing device for separating and recycling a metal composite waste material. The rotational flow electrolyzing device comprises an anode basket, a liquid intake channel, a power supply, an anode mud channel, an anode mud collecting tank and a cathode, wherein the cathode is internally provided with the anode basket and a clearance is formed between the cathode and the anode basket; the anode basket is internally filled with a metal composite waste material so as to form an anode integrally; the anode basket is internally provided with a liquid intake channel; electrolyte flows into a metal composite waste material outside the channel via the liquid intake channel, is in full contact with the metal composite waste material for reacting, further penetrates through the anode basket to enter the clearance between the anode and the cathode, and then flows out; metal required to be electrolyzed and purified in the metal composite waste material is dissolved in an ion mode under the specific electrode potential and is separated out from the cathode; although metal with low electrode potential is dissolved at the anode, the metal cannot be separated out at the cathode, and metal with high electrode potential is remained at the anode as anode mud, and flows into an anode mud collecting tank via the anode mud channel. According to the invention, metal can be separated and recycled efficiently with zero pollution and low cost.

Description

technical field [0001] The invention relates to the separation and recovery technology of composite metal waste, in particular to a swirl electrolysis device for separating and recycling metal composite waste. Background technique [0002] At present, the recycling of metal waste has become the consensus of people. The existing metal waste recycling methods in China mainly include pyrometallurgy, mechanical flotation, dissolution, electrowinning and traditional electrolysis. Pyrometallurgical method has serious secondary pollution, low recovery rate, and expensive treatment equipment; mechanical flotation method has expensive equipment, cumbersome process flow, and low recovery rate; dissolution method has high cost, high acid consumption, serious environmental pollution, and difficult regeneration of some metals ; Although the traditional electrolysis method has no pollution to the environment, it has high energy consumption, high cost, long production cycle, and phenomena ...
