An important part of the recycled aluminum industry is the smelting of waste aluminum, but in the smelting process will produce a lot of smoke, there are a lot of harmful substances in the smoke, whether it is a great threat to the environment or human health, therefore, to explore and implement effective flue gas control measures to promote the sustainable development of the recycled aluminum industry is of great significance.
Waste aluminum smelting makes waste aluminum materials get effective recovery and reuse, through the smelting process, waste aluminum is converted into high-quality aluminum alloy, waste aluminum recycling is mainly through fire smelting, in the process, will use fuel, waste aluminum itself and additives will produce different oxides of gas, as well as various metal oxides and non-metallic oxides of particulate matter, These pollutants will not only pollute the environment, but also endanger people’s lives.
The waste gas of the recycled aluminum industry will produce particulate gas and gaseous pollutants, and the particulate gas is mainly metal oxides and non-metallic oxides, which will also produce gas pollution.
The flue gas catcher is a new type of heavy-duty dry purification treatment device that we have independently developed and owned all intellectual property rights using a new combination of materials and processes. It is composed of multiple groups of metal DPF carriers in parallel, which can reach the blackness level of Ringelmann or below.
For the treatment of nitrogen oxides, we can use selective catalytic reduction method to convert NOx into nitrogen and water through the action of catalysts, thereby reducing NOx emissions.
The flue gas treatment generated in the smelting process of waste aluminum is a systematic project, which needs to comprehensively consider the characteristics and composition of the flue gas, adopt a variety of effective technologies and methods for comprehensive treatment, by optimizing the smelting process, strengthening the pretreatment of raw materials, using efficient dust removal and exhaust gas discharge equipment, effectively reduce the impact of flue gas on the environment, and promote the green development of the recycled aluminum industry. Enterprises need to continuously improve their environmental awareness and technical level to contribute to sustainable development.
