Problems solved by technology

[0006] Trace elements that are physically mixed or mixed with slurry cannot be completely dissolved in ammonium phosphate and fully undergo chemical reactions. The solubility is poor, and some trace element salts are insoluble in water and cannot be absorbed by plants, resulting in waste of nutrients;

Abstract

The invention discloses a production method of ammonium phosphate containing trace elements. The production method is characterized by adopting a manner of dissolving by phosphoric acid and carrying out full ammonolysis reaction on oxides or salts containing trace elements in the ammonium phosphate production process, and specifically comprises the following steps: adding oxides or salts containing trace elements into an acidolysis tank; recovering a scrubbing solution, phosphoric acid and water from an ammonium phosphate scrubbing system and mixing and stirring; fully decomposing the oxides or salts containing trace elements to ions or complexes to form a phosphoric acid solution containing trace elements; conveying to an acid preparation tank of a tubular reactor by a feed pump; adding phosphoric acid, the scrubbing solution and process water to mix; quickly ammonifying in a tubular reactor and grouting and pelleting in a pelletizer; and then drying, sieving, cooling and wrapping to obtain an ammonium phosphate compound fertilizer containing trace elements. The ammonium phosphate compound fertilizer containing trace elements obtained by adopting the method has good solubility.

Description

technical field [0001] The invention relates to the field of compound fertilizers, in particular to an ammonium phosphate compound fertilizer containing boron, zinc, copper, selenium, iron, manganese, sodium, sulfur, molybdenum, iodine, sodium trace metals or non-metallic elements. Background technique [0002] Ammonium phosphate is a binary quick-acting compound fertilizer that contains nitrogen and phosphorus, two essential nutrients for plant production. Common ammonium phosphates include monoammonium phosphate (MAP) and diammonium phosphate (DAP). [0003] Facing the impact of overcapacity and severe market saturation, it is imperative for fertilizer manufacturers to pursue a differentiation strategy. The diammonium phosphate production process and product quality are single, and its binary compound fertilizer has certain limitations. With the rise of the multi-component compound fertilizer industry and the progress of its technology, the current diammonium phosphate pro...
