Изобретение относитс к технолоии получени кормового дикальций- осфата при кислотной переработке риродных фосфатов.The invention relates to a process for the production of feed dicalcium-ospate in the acidic processing of natural phosphates.
Цель изобретени - увеличение скорости фильтрации и повышение питательной ценности готового продукта.The purpose of the invention is to increase the filtration rate and increase the nutritional value of the finished product.
Способ осуществл ют следующим образом .The method is carried out as follows.
Пример 1. 3,972 т очищенной и обесфторенной экстракционной фосфорной кислоты, содержащей, г/л: PyOs 170; 4 16; СаО 1,4; F 0,4, смешивают с 2,845 т раствора нитрата кальци , содержащего, г/л: СаО 140; F 0,07; 0,03, и добавл ют 0,082 т аммиака до рН 4,5. Процесс ведут в течение 1 ч при 70°С. Смесь фильтруют и отдел ют 1,6 т осадка дикальцийфосфата. На фильтр, на осадок дикальцийфосфата, подают предварительно упаренную морскую воду. Упарку морской воды ведут в выпарном аппарате при температуре кипени до содержани в ней солей 11,8 мас.%.Example 1. 3,972 tons of purified and defluorinated extraction phosphoric acid containing, g / l: PyOs 170; 4 16; CaO 1.4; F 0.4, mixed with 2.845 tons of calcium nitrate solution containing, g / l: CaO 140; F 0.07; 0.03, and 0.082 tons of ammonia is added to pH 4.5. The process is carried out for 1 h at 70 ° C. The mixture is filtered and 1.6 t of dicalcium phosphate precipitate is separated. On the filter, on the sediment of dicalcium phosphate, pre-stripped one seawater is fed. The evaporation of seawater is carried out in an evaporator at a boiling point to a salt content of 11.8% by weight.
