    摘要: The invention relates a floating entrainment metallurgical process. In this process, the reaction gas and the powdery materials are injected into the reaction furnace, aiming to obtain a controllable highly rotating and floating state and reach the ignition point under the high-temperature radiation of the reaction furnace to combust intensely. Meanwhile, the rotating fluid injected in the reaction furnace will drive the furnace gas, and forms a relatively low-temperature circular backflow protection area around the rotating fluid. The reaction gas is tangentially fed into the rotating generator along numbers of rotary channels to form a controllable rotating airflow, in addition, a conical exit air controller that can be moved up and down is adopted to control the exit area of the rotating generator, thus controlling the velocity of the reaction gas into the reaction furnace; the powdery materials fall freely around the reaction gas and are involved in the high-speed rotating airflow, forming a rotating fluid, of which the powdery materials are highly dispersed into the reaction gas, moving downwards along the radial high-speed rotating axle. For the purpose of this invention, a steplessly adjusted reactor is as well referred to in this invention.

    摘要: The invention relates to a suspension smelting furnace comprising a reaction shaft (1), an uptake shaft (2), and a lower furnace (3), as well as a concentrate burner (4) for feeding reaction gas and fine solids into the reaction shaft (1) of the suspension smelting furnace. The concentrate burner (4) comprises a fine solids discharge channel (5) that is radially limited by the wall (6) of the solids discharge channel, a fine solids dispersion device (7) in the fine solids discharge channel (5), an annular reaction gas channel (8) that surrounds the fine solids discharge channel (5) and is radially limited by the wall (9) of the annular reaction gas channel (8), and a cooling block (10) that surrounds the annular reaction gas channel (8). The cooling block (10) is a component that is manufactured by a continuous casting method. The cooling block (10) is attached to the arch (11) of the reaction shaft (1) and the wall (9) of the annular reaction gas channel (8), so that the discharge orifice (12) of the annular reaction gas channel (8) is formed between a structure (13), which is jointly formed by the cooling block (10) and the wall (9) of the annular reaction gas channel (8), and the wall (6) of the solids discharge channel. The invention also relates to a concentrate burner (4) for feeding reaction gas and fine solids into the reaction shaft (1) of a suspension smelting furnace.
