Grease electric furnace dust collector

Grease electric furnace dust collector is currently the domestic dust removal equipment for handling electric furnace smoke. It is based on the fact that the smoke generated by electric furnaces is fine and sticky. In order to make the bag dust collector operate normally at an appropriate resistance level, the electric furnace dust collector is required to have strong The dust removal capacity is high, so long bag low pressure large pulse bag dust collector is selected as the dust removal equipment. This kind of equipment has achieved good results in applications in electric furnace steelmaking, blast furnace coal injection, sintering, refractory, carbon black, cement and other industries.

The main features of the grease electric furnace dust collector are dust removal, high filtration load, long dust bag, small footprint, low injection pressure, small maintenance workload, easy replacement and installation of dust filter bags, and under the same air volume, it can Compared with back-blowing bag dust collectors, investment, operating power consumption, floor space, and equipment weight have been significantly reduced.

Characteristics of smoke:

1. Smoke components: The smoke emitted during electric furnace steelmaking contains the following components: FeO2, FeO, SiO2, Ae2O3, CaO, MgO, ZnO, MnO and a small amount of CuO, PbO, and C; the gas components mainly include: CO2, CO, O2 and N2, etc.; as well as SO2 and fluoride.

2. Dust concentration: The dust concentration of the flue gas discharged during oxygen blowing can reach up to 30g/m3;

3. Dust particle size: fine and sticky. More than 80% of dust has a viscosity of less than 10 μm. The grease contained in scrap steel and the oil-containing burners used in steelmaking are all dust produced by steelmaking. They are highly viscous and cannot be easily removed.

Smoke exhaust method of grease electric furnace dust collector:

There are many smoke exhaust methods for steelmaking electric arc furnaces, which can be roughly divided into: smoke exhaust outside the furnace, smoke exhaust inside the furnace, combined smoke exhaust inside and outside the furnace, and roof smoke exhaust. The smoke exhaust method can be determined by analysis and comprehensive comparison based on requirements such as smelting steel type, process operation, process layout, plant conditions, water source conditions, small investment, environmental protection, labor hygiene and energy conservation, as well as maintenance and management levels. The basis is that users generally adopt the form of smoke exhaust outside the furnace.
