Embodiment Construction
[0011] Referring to the accompanying drawings, the present invention is a new process for removing dust from electric furnace flue gas by recirculating part of the flue gas. 6. Booster fan 7, deflector 8, air supply equalizing pipe 9, air outlet 10, roof cover 11, air curtain fan 12, safety valve 13, bag filter 14, dust removal fan 15, chimney 16.
[0012] The electric furnace 1 is a steelmaking equipment, and there is a certain distance from the roof cover 11 under the roof cover 11;
[0013] Furnace hole smoke exhaust pipe 2 is made of steel pipe, and steel pipe carries out pipe-to-pipe welding and encircles circular shape, and cooling water is passed in the steel pipe. The inlet end of the furnace hole exhaust pipe 2 is connected to the furnace cover of the electric furnace, and the outlet end is opposite to the water-cooled flue 3;
[0014] The water-cooled flue 3 is made of steel pipes, and the steel pipes are welded pipe-to-pipe to form a circle. Cooling water passes th...
