The converter steelmaking gravity dry method dedusting and afterheat recycling device can recycle the powder particle high-heat flue gas generated by the converter after the treatments of decreasing the temperature and dedusting by a series of devices and realize the good performance of energy conservation and emission reduction.

Description

technical field [0001] The invention relates to a converter steelmaking dedusting and waste heat recovery device, in particular to a device for realizing energy saving and emission reduction by using gravity dry dust removal and waste heat recovery and reuse, and belongs to the technical field of energy saving and environmental protection in iron and steel smelting. Background technique [0002] As the concept of scientific development continues to gain popularity, energy saving and emission reduction in the industrial production process has become a matter of great concern and attention. In the field of steelmaking, the emission of dust particles is very serious to the environment, and the emission of waste heat is harmful to the climate. Bad influence, also produces huge waste at the same time. Therefore, how to do a good job in the environmental pollution and waste heat recovery of the dust particles discharged from the steelmaking converter is a difficult problem that th...

Problems solved by technology

In the prior art, there are mainly dry dedusting devices for the treatment of steelmaking waste gas, but the dedusting effect of this device is not good and the waste heat cannot be recycled, the cost is expensive, and the operation model is complicated. Another way is the wet dedusting device, but it is also It does not have the efficiency of waste heat recovery and utilization, and the dust removal effect is poor and the structure is complicated
