Description

Technical Field

[0001] The utility model relates to the field related to phosphoric acid concentration, in particular to a high-efficiency automatic separator. Background Art

[0002] The process principle and method of concentration The phosphoric acid produced by the dihydrate method has a mass fraction of only 20% to 24% P2O5. When producing heavy calcium, the mass fraction of phosphoric acid is required to be above 45% P2O5, so the dilute phosphoric acid must be concentrated. The concentration of phosphoric acid is considered to be a difficult operation. This is because wet-process phosphoric acid contains about 2% H2SO4 and about 2% H2SiF6 (in terms of F), which are highly corrosive. At the same time, during the heating and concentration process, impurities in the dilute phosphoric acid that are already in a supersaturated or saturated state precipitate as the concentration of phosphoric acid continues to increase and deposit on the surface of the vessel wall. In addition, there is also the problem of handling waste gas during the concentration process. The methods for concentrating phosphoric acid can be divided into two categories based on their heating methods, namely direct heating and indirect heating evaporation.

[0003] In the prior art, a separator is usually used to achieve heating and concentration of dilute phosphoric acid. A spray structure is also arranged inside the separator to wash the flue gas after separation and reduce the phosphorus content in the exhaust gas. However, the traditional spray structure is usually fixed and has a fixed spray range, which is not sufficient for spraying and washing the flue gas. Utility Model Content
