Abstract:
A swirling column nozzle comprises a nozzle body with an air chamber defined therein; an outlet portion, a feed pipe penetrating through the air chamber and extending to the outlet portion, an oxygen supplying portion disposed on the nozzle body, the outlet portion is formed with a swirling guide part for moving a mixture of the oxygen gas and the concentrate downwardly in the form of a swirling column. Further, a swirling column smelting equipment and a method thereof are disclosed. The air flow moves downwardly in a substantially swirling column, so the chemical reaction path and reaction time are extended remarkably, allowing the reduction of the height of the reaction shaft.
