Description
Technical Field
The invention relates to the technical field of electrolytic aluminum, in particular to a treatment method of electrolytic aluminum.
Background
The carbon-containing hazardous waste of electrolytic aluminum comprises carbon slag, waste cathode carbon blocks (comprising carbon materials such as tamping paste, side carbon blocks and the like), anode scrap cleaning materials, overhaul slag and the like, and is listed in national hazardous waste address book (HW 48 nonferrous metal smelting waste-salt slag and scum generated in the process of electrolytic aluminum because of containing toxic substances such as soluble fluoride and the like). Carbon slag is formed in an electrolytic tank due to carbon particles falling off caused by various reasons such as long-term erosion and washing of anode carbon blocks and cathode carbon blocks by electrolyte, uneven combustion, selective oxidation, unqualified quality and the like in the electrolytic aluminum production process. Because of being soaked and permeated by electrolyte for a long time, the content of fluoride salt in the carbon slag is very high, the main components accounting for about 60-70% of the weight of the carbon slag are cryolite, sub-cryolite and carbon, and the balance is aluminum oxide, sodium fluoride, calcium fluoride, magnesium fluoride, lithium fluoroaluminate, potassium fluoroaluminate and the like. It is counted that about 10-15 kg of anode carbon slag is produced per ton of raw aluminum, the aluminum electrolysis capacity in 2017 in China is about 4490 ten thousand tons, and the anode carbon slag is about 674 ten thousand tons. And (3) carrying out overhaul slag, wherein the aluminum electrolysis cell generally runs for 5-8 years, and the planed furnace bottom materials are commonly called overhaul slag because of severe damage. The overhaul slag mainly comprises waste cathode carbon blocks (containing steel bars), waste refractory materials (refractory bricks, insulating bricks, dry anti-seepage materials and the like). The waste cathode carbon block contains about 70% of carbon, part of carbon is graphite carbon, contains about 30% of fluoride salt, mainly Na3AlF6, naF, caF2 and NaCN, and contains a small amount of Al2O3, free metal impurities and the like. The components of the waste cathode carbon block which are harmful to the environment are as follows: naF is easy to dissolve in water, and F-is leached out, so that the hazard is extremely high; na3AlF6 is easy to decompose to generate NaF and AlF3 when heated, so that the method has certain hazard; cyanide exists in the form of NaCN or Na4[ Fe (CN) 6] and is about 0.1 to 0.2 percent although the content is very low, the cyanide is easy to leach CN < - > when meeting water, HCN is released by reaction with water, and the cyanide has extremely high toxicity. The anode scrap is required to be re-mixed into the production of a new anode as a raw material, so that the surface electrolyte, soft anode scrap and steel claw rust of the anode scrap are required to be cleaned by using iron shots before use, and the generated waste residues are the anode scrap cleaning material or shot blasting anode scrap cleaning material, and the main components and the contents are 40% of carbon powder, 55% of electrolyte, 5% of rust and iron shots and the like are estimated initially. Because of the presence of electrolytes, the leachate fluoride concentration of such waste exceeds the 100mg/L standard and is also a solid hazardous waste.
During the process of electrolytic aluminum, crushing treatment is needed, and catalyst is added during crushing, but in the existing catalyst adding process, excessive catalyst is often needed to be added in order to ensure the best catalytic effect, so that the waste problem exists. In order to solve the above problems, the present invention proposes a method for treating electrolytic aluminum.
