The present invention discloses a comprehensive treatment device and treatment method for electrolytic aluminum overhaul
slag. The device is a diaphragm
electrolysis device, comprising a plurality of unit cells, wherein the unit cells are separated by an
anode and a
cathode. In the unit cells, an anion membrane is arranged near the
anode, and a cation membrane is arranged near the
cathode. A partition with a chamber is arranged between the
anode, the anion membrane, the cation membrane, and the
cathode, respectively, to separate the unit cells from the anode to the cathode into an anode chamber, a solution chamber, and a cathode chamber; multiple groups of unit cells are connected in series, and the cells are connected in parallel, or multiple groups of unit cells are connected in parallel and the cells are connected in series. The method comprises the steps of sorting and crushing,
wet grinding and immersion, filtering, and diaphragm
electrolysis. This scheme can effectively classify and treat the overhaul
slag and dispose of it harmlessly. The diaphragm
electrolysis method is adopted to enrich
sodium fluoride while electrochemically breaking
cyanide, so as to realize the recycling of aluminum
slag, carbon blocks,
refractory materials, and
sodium fluoride.
