The invention discloses a method for deeply recovering phosphorus and vanadium from molten iron containing phosphorus and vanadium, which comprises the following steps: treating the molten iron containing phosphorus and vanadium by adopting an oxygen blowing method, in the oxygen blowing method, directly blowing mixed gas into the molten iron by utilizing a spray gun, the volume concentration of the oxidizing gas is 18%-50%. The method has the advantages of improving the recovery rate of phosphorus and vanadium, reducing the smoke amount and the like, and also has the characteristics of low cost, short process, environmental friendliness, less carbon emission, high heat utilization rate, full utilization of resources and the like.

The application discloses a rotary floating entraining metallurgical nozzle, which comprises a reaction gas channel and a material channel which are sleeved with each other, an entraining channel is arranged concentrically in the reaction gas channel, a rotating shaft is arranged in the center of the entraining channel, a blade assembly is connected to the bottom of the rotating shaft, a driving device is arranged on the top of the rotating shaft, exhaust holes are arranged on the wall of the entraining channel, and the upper ends of the reaction gas channel, the material channel and the entraining channel are not communicated with each other. The application has the advantages of simple structure, better mixing reaction effect of gas and material particles, low smoke dust rate, and more concentrated reaction in the center, thereby effectively reducing the erosion on the wall of a reaction tower.
