Problems solved by technology
[0004] The invention can add waste slag to the inside of the waste slag collection box by using the gravity of the waste slag by setting a guide mechanism, a capping mechanism, a waste slag collection box and a limit mechanism, and at the same time add water to the inside of the storage box for heat exchange, but it can only The heat inside the waste residue is recovered once, which causes a waste of energy, and the recovered energy is only the heat energy in the water body, and the energy form is relatively simple, which reduces the recovery efficiency

[0040] As an embodiment of the present invention, refer to Figure 4 The power generating mechanism includes two first magnets 16 symmetrically and fixedly installed on the inner wall of the second device slot 15, and the outer edge of the rotating shaft 11 is fixedly installed with an induction coil 17 cooperating with the two first magnets 16 inside the second device slot 15 The inner wall of the second device slot 15 is also fixedly installed with two commutators 23 electrically connected to the two ends of the induction coil 17 respectively.
[0041] After the rotating shaft 11 rotates, it will drive the induction coil 17 inside the second device slot 15 to cut the magnetic field lines between the two first magnets 16, and then generate an induced current inside the induction coil 17. The device 23 is electrically connected with the power storage device, so as to complete the storage of the current generated by the induction coil 17, and then complete the recovery of energ...

The invention relates to the technical field of iron smelting, in particular to an iron and steel smelting waste heat utilization system which comprises a shell, a circular groove is formed in one side of the interior of the shell, a water storage tank used for containing water is formed in the other side of the interior of the shell, and a feeding pipe used for loading iron and steel smelting waste is inserted into the circular groove. And a heating mechanism for heating the water body is arranged between the circular groove and the water storage groove. According to the waste heat recovery device, waste heat in the feeding pipe is continuously transferred to water in the water storage tank, the water is heated, primary recovery of heat is completed, when waste heat in steel smelting waste is recovered, a first rotating wheel and a second rotating wheel can continuously rotate and drive a rotating shaft to continuously rotate, and after the rotating shaft rotates, the waste heat in the water storage tank is recovered. The two commutators are arranged in the induction coil, induction current can be generated in the induction coil, the current generated by the induction coil can be stored only by electrically connecting the two commutators with the power storage equipment, and then energy is recycled.
Description
technical field [0001] The invention relates to the technical field of iron smelting, in particular to an iron and steel smelting waste heat utilization system. Background technique [0002] Iron and steel smelting is the general term for steel and iron metallurgical processes. According to the carbon content, industrially produced iron is divided into pig iron (with a carbon content of more than 2%) and steel (with a carbon content of less than 2%). Most of the modern ironmaking Blast furnace ironmaking is used, and direct reduction ironmaking method and electric furnace ironmaking method are used in some cases. Steelmaking mainly uses pig iron smelted in blast furnaces, sponge iron smelted by direct reduction ironmaking, and scrap steel as raw materials, and is smelted into steel by different methods. The basic production process is to smelt iron ore into pig iron in an ironmaking furnace. Then pig iron is used as raw material, smelted into steel by different methods, and...
