| titleOfInvention | System and method for extracting iodine from waste solution of polaroid manufacturing process |
| abstract | The invention discloses a system and a method for extracting iodine from a waste solution in a polaroid manufacturing process, wherein the system comprises a cooling crystallization tank, a borax dehydrator, a filtrate relay tank, a first filtrate collecting tank, a crude iodine dehydrator and a second filtrate collecting tank which are sequentially connected; the inlet end of the cooling crystallization tank is connected with a waste solution inlet pipe; a borax collecting tank is arranged at the solid outlet end of the borax dehydrator; the inlet end of the solution relay tank is connected with a sulfuric acid storage barrel and a sodium hypochlorite storage barrel through a sulfuric acid inlet pipe and a sodium hypochlorite inlet pipe respectively; a solid outlet end of the coarse iodine dehydrator is provided with a coarse iodine collecting tank; the inlet end of the second filtrate collecting tank is connected with a sodium hydroxide storage barrel and a sodium thiosulfate storage barrel through a sodium hydroxide inlet pipe and a sodium thiosulfate inlet pipe respectively, and the outlet end of the second filtrate collecting tank is connected with a treatment fluid outlet pipe. The invention can extract iodine with higher purity, has high recovery rate, strong environmental protection and high system automation degree, and reduces labor force and cost. |
