Abstract
The invention discloses a uniform addition mode of elemental sulfur in ammonium phosphate. The uniform addition mode is characterized in that the elemental sulfur contained in ammonium sulphate phosphate contained in a final product is uniformly distributed in solid ammonium phosphate. The addition state of the elemental sulfur in the ammonium phosphate is a solid state or a liquid state. The uniform addition mode of solid sulfur comprises the following steps: mixing a sulfur solid with a nonionic surface active agent and water to prepare a uniform sulfur suspension liquid or a sulfur colloid, and then adding the sulfur suspension liquid or the sulfur colloid to raw material phosphoric acid or reaction slurry obtained after the phosphoric acid is neutralized by using ammonia. The uniform addition mode of the liquid sulfur comprises the following steps: mixing the liquid sulfur with the nonionic surface active agent, and then adding to the raw material phosphoric acid or the reaction slurry obtained after the phosphoric acid is neutralized by using the ammonia, or firstly adding the nonionic surface active agent and then adding the liquid sulfur to the raw material phosphoric acid or the reaction slurry obtained after the phosphoric acid is neutralized by using the ammonia.
Description
Technical field
The present invention relates to the preparation method containing ammonium phosphate sulfate, particularly, relate to the even addition manner of a kind of elemental sulfur in phosphorus ammonium.
Background technology
Simple substance sulfenyl phosphorus ammonium contains the sulphur of high density, and the expense transported and use is low compared with other sulfur fertilizers; Secondly, slowly, validity period is long, and simple substance sulfenyl phosphorus ammonium can replace the lower concentration sulfur fertilizers such as sulphur ammonium and calcium superphosphate, is just causing the extensive concern of people in recent years in its release.Due to the hydrophobic nature of sulphur, the avidity of sulphur and phosphorus ammonium is poor, adopts simple means to be difficult to make sulphur together with phosphorus ammonium Homogeneous phase mixing.At present; external common simple substance sulfenyl ammonium phosphate production method mainly wraps up one deck sulphur at phosphorus ammonium outside surface; namely in tablets press, spray one deck elemental sulfur to the outside surface of phosphorus ammonium, its shortcoming is that sulphur easily comes off in transport, transport process, and sulphur is not easily absorbed by farm crop in application.Another kind method is, in phosphorus ammonium production process, liquid sulfur is added to granulation together in phosphor ammonium slurry, by the dissemination of nozzle, spray granulating obtains simple substance sulfenyl ammonium phosphate product, due to the limitation of this technique, the uniform product of component can not be obtained, and leave potential safety hazard often to subsequent handling and transport.
Summary of the invention
The technical problem to be solved in the present invention is: the present invention realizes the scattering problem of sulphur in phosphorus ammonium by adding nonionic surface active agent, and the dispersing property of sulphur in phosphorus ammonium is better, and the danger in production is less.
