| titleOfInvention | Arsenic purifier is removed in phosphoric acid vulcanization of wet process |
| abstract | The utility model discloses a wet-process phosphoric acid sulfuration arsenic removal purification device, which comprises a screw conveyer, a vulcanizing agent bin, a Venturi mixer, a reaction tank and a solid-liquid separation device; a vulcanizing agent enters a vulcanizing agent bin through a spiral conveyor, and an outlet of the vulcanizing agent bin is connected with a vulcanizing agent inlet arranged on the Venturi mixer; the outlet of the Venturi mixer is connected with the inlet of the reaction tank, and the outlet of the reaction tank is connected with the solid-liquid separation device; the venturi mixer is also provided with a phosphoric acid solution inlet; a compressed air inlet is arranged on the vulcanizing agent bin; the reaction tank is an airtight device. Through adopting the venturi mixer to replace traditional stirring for multiple material is misce bene in the venturi mixer, and equipment area is little, unpowered consumption, the energy can be saved and the cost. Meanwhile, the reaction tank is an airtight device, and the vulcanizing agent does not need to be independently prepared into solution, so that the overflow of hydrogen sulfide gas generated in the reaction is effectively prevented, the field operation safety is improved, and the environment is protected. |
