<p>A spin-suspension-entrainment metallurgical process. A reaction gas (12) and a powdered material are sprayed into a reaction furnace (13) to achieve a controllable highly dispersed spin suspension status, and reach the ignition temperature under the high-temperature radiation of the reaction furnace (13) to undergo an intense combustion reaction. Meanwhile, a spin fluid (15) sprayed into the reaction furnace (13) drives the furnace gas, so as to form a reflux protective layer (14) of a relatively low temperature around the spin fluid. The reaction gas (12) in multiple turnaround channels flows along the tangent to enter a swirl generator (2), to form a controllable rotating gas flow. A conical outlet wind speed controller (9) capable of moving vertically is used to control the area of the outlet of the swirl generator (2), and control the speed that the reaction gas (12) enters the reaction furnace (13). A powdered material flow (11) falls freely along the periphery of the reaction gas (12), and is entrained into the high-speed rotating gas flow, so as to form the spin fluid (15) rotating radially at a high speed and moving vertically along the axial direction where the powdered material is highly dispersed in the reaction gas. Also provided is a reactor for implementing the method and capable of stepless adjustment.</p> |
