Latest Patents
One of Junqing Pan's latest patents is titled "Method and apparatus for sodium slag recovery." This invention focuses on the preparation of high purity sodium and the safe treatment of sodium calcium slag. The disclosed method utilizes a gravity separation—controllable combustion—alkaline liquor leaching process. The steps include subjecting liquid sodium slag to gravity stratification to obtain pure metallic sodium and high calcium content sodium slag, roasting the high calcium content sodium slag, and leaching the roasting slag with alkaline liquor to produce sodium hydroxide and calcium hydroxide. This method offers high efficiency in separating sodium and calcium, reduces separation time, and ensures a safe and continuous production process.
Another notable patent is the "Method for recovering lead oxide from waste lead paste." This method involves dissolving pre-desalted lead plaster using a complexing agent solution, which reacts with PbO to generate lead complexing ions. The process includes adding a precipitant to the lead-containing solution, resulting in a lead salt precipitate and the regeneration of the complexing agent. The final recovery rate of lead oxide can reach 99% or more, showcasing the effectiveness of this innovative approach.
