Description

Technical Field

[0001] The invention relates to the field of liquid water-soluble fertilizers, and in particular to a high-concentration chelated water-soluble fertilizer reactor and a formula. Background Art

[0002] Water-soluble fertilizer refers to a compound fertilizer containing nitrogen, phosphorus, potassium, calcium, magnesium, trace elements, amino acids, humic acid and alginic acid that can be completely dissolved in water. Compared with traditional superphosphate and granulated compound fertilizers, water-soluble fertilizers have obvious advantages. It is a fast-acting fertilizer with good water solubility and no residue. It can be completely dissolved in water and can be directly absorbed and utilized by the roots and leaves of crops.

[0003] The chelate reactor is a commonly used reaction equipment in chemical plants. It mainly drives the stirring shaft through a motor and uses stirring blades to fully stir the reactants to make them fully mixed. Currently, many liquid water-soluble fertilizers are mainly mixed by reactor equipment.

[0004] However, in the current mixing reaction, the mixing effect of the water-soluble fertilizer cannot be optimal due to the basic technical problems that are difficult to overcome, such as the back mixing of the reactor and the uneven heating system and heat exchange difficulties of the reactor. That is, the chelating agent and the metal ions cannot fully react. Even if the chelating agent is added in excess, the chelate will precipitate or precipitate. Therefore, how to effectively utilize the unchelated metal ions or the precipitated chelate is a relatively important technical issue at present. Summary of the invention
