Example Embodiment
[0028] Such as figure 2 As shown, a gas smelting furnace provided by the present invention includes a furnace body 1, a chimney is connected to the upper end of the furnace body 1, a spiral dust removal device 2 is arranged between the furnace body and the chimney, and an induced draft fan 3 is connected to the chimney. The exit leads to a pool 4. Through the dust removal device and the pool, the exhaust gas of the melting furnace can be fully purified.
[0029] The furnace body 1 is provided with a feed port 11 and a molten iron discharge port 12, and a feeding mechanism is provided on the feed port. Between the feed port 11 and the discharge port 12 in the furnace body 1, at least two rows of fuel gas and combustion-supporting gas nozzles surrounding the side wall of the furnace body are arranged from top to bottom; On the setting height of the furnace body, this position is the melting section of the melting furnace. The nozzle here can be called the melting section nozzle 1...
