Smelting system

The utility model discloses a smelting system which comprises a feeding device, a smelting furnace, a surface air cooler and a dust collecting device, a discharging port of the feeding device is communicated with a feeding port of the smelting furnace, a flue outlet of the smelting furnace is communicated with an air inlet of the surface air cooler, and an air outlet of the surface air cooler is communicated with an air inlet of the dust collecting device. Smoke generated by the device is dedusted through the surface air cooler and the dust collecting device, so that tail gas and smoke dust are ensured to reach the national emission standard; and the recovered smoke dust is returned to the smelting system through the feeding device. 本实用新型公开了一种熔炼系统，包括进料装置、熔炼炉、表冷器和收尘装置，所述进料装置的出料口与所述熔炼炉的进料口连通，所述熔炼炉的烟道出口与所述表冷器的进风口连通，所述表冷器的出风口与所述收尘装置的进风口连通。本实用新型产生的烟气通过表冷器+收尘装置进行除尘，确保尾气烟尘达到国家排放标准；回收的烟尘通过进料装置再返回熔炼系统。
