Fecha de publicación: 01/12/2017 Fuente: WIPO "circular economy" The utility model provides a prevent hot stove in ore deposit, rotary kiln of furnace charge splash and unite smelting system, the fire coal gets into gas producer through the coal bunker, and the reentrant gas producer of steam pocket is brought into by air blower to the air, and coal gas, a series of processing of coal gas process are down gone up to coal gas, lower coal gas, slag in the gas producer production, and it is combustion -supporting to send into the rotary kiln, and the CO that the hot stove in ore deposit produced sends into the rotary kiln, and the material of rotary kiln prereduction changes over to the hot stove in ore deposit over to. The utility model discloses beneficial effect: the coal gas of gas producer output gets into the rotary kiln after the integrated treatment of this system, for the rotary kiln replenishes required gas, adopt and preheat the raw materials, and the material obtains the intensive drying, has reduced and has gone into the moisture of stove, therefore reduced the produced burner gas volume of the smelting process, is favorable to stablizing the working of a furnace, guarantees the safety in production, reduces heat and stops time scalar sum time. Make full use of the heat of each station, fuel economy, accord with the environmental protection requirement.
