1. Improvement of production process
1. Optimize the smelting process: improve the furnace structure, increase furnace temperature and combustion efficiency, and reduce exhaust gas emission concentration.
2. The use of advanced furnace technology: such as high-efficiency combustion technology, oxygen combustion technology, double furnace combustion technology, etc., can reduce exhaust gas emissions and improve energy utilization.
3. Optimize alloy ingredients and limestone additives: According to the physical and chemical properties of limestone, adjust its addition amount and ratio to reduce the CO and SO2 content in the exhaust gas.
4. Minimize dust emissions during raw material crushing.
5. Using microwave heating technology: It can improve the temperature uniformity in the furnace and reduce the large amount of nitrogen oxide emissions produced in areas with excessive temperatures.
2. Pollution Control
1. Wastewater treatment: The wastewater generated in the production of carbon-manganese ferroalloy contains high concentrations of suspended solids and heavy metal ions. Medium-carbon ferromanganese alloy manufacturers can use precipitation, ion exchange, membrane separation and other technologies for treatment.
2. Exhaust gas treatment: Using high-temperature and high-concentration exhaust gas purification technologies, such as wet dust removal, desulfurization and denitrification, etc., can reduce particulate matter and pollutant emissions in exhaust gas. Exhaust vent covers, flue gas purification facilities, etc. can also be installed to control and reduce exhaust emissions.
3. Waste residue treatment: Waste residue contains a certain amount of metal elements and other useful components, which can be recycled through magnetic separation, gravity separation and other methods to minimize the generation of waste residue and environmental pollution.
4. Establish a waste recycling system: classify waste for collection, reuse and resource utilization to minimize environmental pollution.
3. Resource recycling
1. Promote the recycling of medium carbon manganese ferroalloys: Recycle waste residue, waste water, etc. into the alloy production process to reduce the need for fresh raw materials, reduce resource consumption and environmental pollution.
2. Research and develop manganese slag resource utilization technology: Utilize manganese slag as a resource, such as preparing fine particles of ferromanganese alloy, aluminum-manganese alloy, etc., to change the traditional problems of disorderly stacking of waste slag and large area occupied.
3. Carry out circular economy cooperation: Cooperate with other industries to provide wastewater, waste gas and other resources and wastes in the production of medium-carbon manganese ferroalloy as raw materials or energy to other industries to achieve resource recycling.
