Abstract

The invention belongs to the smelting field, and in particular relates to a system and method for roasting siderite. Coal gas replaces common soft coal and is used as a fuel for roasting siderite. As the principal components of the coal gas are carbon monoxide and hydrogen, harmful gases such as sulfide are not generated in the roasting process, so that the environmental pollution can be reduced. The system comprises a belt sintering machine which comprises an ignition device and a trolley for conveying siderite. A fire spraying nozzle is arranged at the bottom of the ignition device which is located above the trolley. A gap is reserved between the ignition device and the trolley. The system further comprises a coal gas supplying device, an air supplying device and a mixing device. The coal gas supplying device is connected with the mixing device, the air supplying device is connected with the mixing device, and the mixing device is connected to the ignition device.

Description

technical field [0001] The invention relates to the field of smelting, in particular to a system and method for roasting siderite. Background technique [0002] In the traditional siderite roasting system, the siderite is placed in the furnace of the sintering device, and an ignition device connected to the furnace is installed on the outer wall of the sintering device; wherein, ordinary bituminous coal with high sulfur and high ash content is placed in the ignition device Combustion is carried out, and then the flame generated by the bituminous coal combustion is blown into the furnace through the ignition device through the blast device, thereby roasting the siderite in the furnace. [0003] However, in this traditional system for roasting siderite, high-sulfur and high-ash common bituminous coal is used in the ignition device for combustion. Due to the high sulfur content of bituminous coal, a large amount of toxic gases such as sulfides are produced during combustion, wh...
