Description
The scrap aluminum that can be used for this process is mainly the waste aluminum produced by the dismantling of electronic waste. This process mainly melts aluminum-containing waste through electricity and burning various fossil fuels, adds slag beaters and refining agents after melting, and physically removes all kinds of scum generated by melting.
During the treatment process, slag breakers and refining agents are used to remove impurities in molten aluminum; The purity of sodium hydroxide required is 100%, the main function is to remove organic impurities, the main components of the slag breaker are sodium fluorosilicate, sodium chloride, potassium chloride, and the refining agent is mainly cryolite; Electricity and natural gas are used to provide the heat needed for melting. The treatment process produces anthracene oil, COD, ammonia nitrogen, petroleum pollution and phenol wastewater, as well as waste gases containing sulfur dioxide, nitrogen oxides, hydrogen chloride and fluoride, which are directly discharged into the atmosphere after treatment.
The raw materials used for aluminum scrap are pure aluminum scrap, which have been sorted and packaged.
Activity Description
This dataset represents the process of producing recycled aluminum rods through melting waste aluminum and subsequent refining. The treatment process includes the consumption of energy and auxiliary materials, as well as the generation of waste gas and wastewater.
Process Description
After waste aluminum undergoes smelting, slagging, refining, slagging and filtration, it is poured and sawed to finally produce aluminum rods.
