Abstract

The invention relates to the technical field of electric furnace steelmaking, and provides an electric furnace steelmaking flue gas efficient power generation system which comprises a steelmaking electric furnace, a combustion settling chamber, a waste heat boiler, a pressure stabilizing energy accumulator, a flue gas treatment system and a power generation system. The heat accumulator is arranged in the combustion settling chamber, the superheater is arranged in the heat accumulator, the steelmaking electric furnace, the combustion settling chamber, the waste heat boiler and the flue gas treatment system are sequentially connected, the input end of the pressure stabilizing energy accumulator is connected with the steam output end of the waste heat boiler, and the output end of the pressure stabilizing energy accumulator is connected with the input end of the superheater. The output end of the superheater is connected with the power generation system. By means of the technical scheme, the problem that in the electric furnace steelmaking process in the prior art, due to the characteristic of periodical fluctuation of flue gas, flue gas waste heat cannot be recycled and reused is solved.

Description

technical field [0001] The invention relates to the technical field of electric furnace steelmaking, in particular to an electric furnace steelmaking flue gas high-efficiency power generation system. Background technique [0002] With the development of the national economy and the continuous improvement of energy conservation and emission reduction requirements for iron and steel production processes, the proportion of electric furnace steelmaking in various steel plants in my country will continue to increase. future development direction. During the smelting process of electric furnace steelmaking, the flue gas flow, temperature and dust content are constantly changing, showing periodic fluctuations. It adopts water-cooled jacket cooling and mechanical air-cooler cooling to ensure the purification treatment of flue gas after cooling, and discharge up to the standard. The waste heat is not fully utilized, and electricity is wasted to cool the flue gas. SUMMARY OF THE INV...
