The yellow phosphorus production method comprises the following steps: S100, preparing raw materials; s200, a raw material pretreatment procedure; s300, burdening and mixing: mechanically mixing the core raw material with the multi-element system additive; s400, an electric furnace smelting procedure: feeding the furnace charge into an electric furnace, and carrying out carbon thermal reduction reaction to generate yellow phosphorus-containing steam; s500, a condensation and collection process: changing the yellow phosphorus vapor into a liquid state through a condensation system, and collecting the yellow phosphorus vapor; wherein the multi-element system additive comprises a fluxing agent, a reaction accelerant and a structure regulator; the method further comprises a process control step, wherein the adding amount of the multi-element system additive is controlled and adjusted through closed-loop feedback based on monitoring data. According to the method, by introducing a multi-element system additive and optimizing process control, the production energy consumption is reduced to a certain extent and the furnace condition stability is improved while the phosphorus reduction rate is increased and the residual phosphorus in the slag is reduced.

This utility model relates to a reaction device, a reaction vessel for resin production, including a stirring shaft and a vessel body. The lower end of the stirring shaft extends into the vessel body along the upper end and is connected to stirring blades and a trigger rod. The upper end of the stirring shaft is connected to a drive motor. The trigger rod includes a rod body perpendicular to the stirring shaft. A groove is formed along the axial direction of the end of the rod body away from the stirring shaft. Limiting grooves are formed on opposite sides of the inner wall of the groove, consistent with the direction of the groove. An alloy contact is provided in the groove. With the cooperation of a spring and a guide block, the alloy contact of this utility model can stably contact the spherical protrusion during stirring, generating regular vibration. This vibration can effectively drive the flow of reactants near the side wall in the vessel body, making the reactants more thoroughly mixed. At the same time, the vibration can reduce the adhesion of reactants to the side wall of the vessel body, significantly improving reaction efficiency, reducing material waste and equipment cleaning difficulty.
