摘要
The present invention relates to a device and a method for recovering a large and dry precipitated solid inorganic final product (3D), consisting of phosphorus, nitrogen and an element X selected from the alkaline-earth metals, from a first fluid (1) consisting of at least one divalent cation X2+ mixed with a second fluid (2) containing phosphorus and nitrogen, said device including at least one first reactor (19) which is intended for a primary crystallization reaction, has any shape, and is connected to a second spiral-shaped reactor (20) for secondary crystallization/deposition.
