★Product introduction of ferrosilicon furnace environmental protection system
The ferrosilicon furnace environmental protection system is an environmental protection equipment system for efficient purification of large amounts of flue gas, dust and harmful gases generated during the high-temperature smelting process of ferrosilicon electric furnaces (submerged arc furnaces). The flue gas emitted during the operation of the ferrosilicon furnace contains high-temperature dust (mainly SiO₂, Fe₂O₃), CO, silicon monoxide, trace fluorides and heavy metal particles. It has the characteristics of high temperature, high dust and high concentration, and has extremely high requirements for the processing capacity and material selection of the environmental protection system.
The system usually consists of a smoke hood collection device, a high-temperature bag dust collector, a cooling system, a flue gas conveying pipeline, an intelligent control system and some flue gas waste heat recovery or tail gas purification units.
★Product features
High-efficiency dust removal
Adopting high-temperature resistant bag dust collectors or electric bag composite dust collectors, the dust removal efficiency is as high as 99.9% or more, and the dust emission concentration can be controlled within 20mg/m³, and some systems can reach below 10mg/m³.
Adapt to high-temperature smelting flue gas
The system temperature resistance design can reach above 260~300°C, and some areas use water cooling or air cooling to ensure long-term stable operation of the system without heat damage.
Segmented cooling design
Reasonably cool the flue gas in grades to prevent condensation, bag sticking and system corrosion, extend equipment life and improve dust removal efficiency.
Dust collection can be recycled
The captured silicon powder or alloy dust has secondary utilization value and can be recycled as industrial raw materials to enhance the comprehensive utilization efficiency of resources.
Automatic control and linkage management
The matching PLC automatic control system can realize the linkage start of the electric furnace operation and the dust removal system, and monitor the key parameters such as air volume, temperature, and pressure difference in real time to ensure safe operation.
Low operating cost and convenient maintenance
The modular structure is adopted, the filter bag is easy to replace and repair, the operating resistance is low, the fan energy consumption is small, and the overall operating economy is good.
Environmental protection meets policy requirements
The system design complies with environmental protection standards such as "Emission Standards for Atmospheric Pollutants from Industrial Furnaces" and "Emission Standards for Pollutants from Ferroalloy Industries" to ensure legal emissions and stable production of enterprises.
Flexible matching of different furnace types
Customized design can be carried out according to ferrosilicon furnaces of different capacities (such as 12500kVA, 25000kVA, 33000kVA, etc.), and it can be adapted to semi-enclosed furnaces, fully enclosed furnaces and other structures.
