| titleOfInvention | Super fine iron oxide desulfurizer preparation facilities |
| abstract | The utility model discloses a preparation device of an ultra-fine ferric oxide desulfurizer, which comprises a stirring device main body, a washing device main body, a filter pressing device main body, a granulating device main body and a drying device main body, wherein ferrous sulfate and sodium hydroxide are added with water to react, and after being stirred for thirty minutes, the mixture is stood, washed, filter-pressed and granulated, and finally dried and packaged, so that the prepared ultra-fine ferric oxide desulfurizer has high removal performance on hydrogen sulfide, has a certain removal effect on thiols such as organic sulfur, inorganic sulfur and the like, and has the sulfur removal precision of more than 0.05 ppm; the desulfurizer is suitable for being used as a super-fine desulfurizer under the conditions of existence or absence of oxygen and carbon dioxide and is applied to sulfide purification with special requirements on gas sources such as natural gas, conversion gas, carbon dioxide gas and the like; the equipment is simple in use, convenient to operate, small in bed resistance, fast in desulfurization and high in purification degree; the physical strength of the materials is high, the materials are not argillized after being soaked in water for 72 hours, the system is pressurized and depressurized in the using process, and the materials are not deformed and crushed. |
