Description
Известные способы получени удобрите тьных и кормовых фосфатов вызывают необходимость складского дозревани промежуточного шодукта и св заны со значительным расходом серной кислоты.Known methods for producing fertilizer and feed phosphates necessitate the storage maturation of the intermediate product and are associated with a significant consumption of sulfuric acid.
Предложенный способ позвол ет получать трикальцийфосфат из промежуточного продукта производства монокальдийфосфата без складского дозревани и без затраты серной кислоты.The proposed method allows to obtain tricalcium phosphate from the intermediate product of the production of monocallium phosphate without storage maturation and without the cost of sulfuric acid.
Предлагаемый способ одновременного -получени удобрительного монокальдийфосфата и кормового трикальцийфосфата, заключаетс в том, что .полученный в производстве монокальцийфосфата, при разложении апатитового концентрата оборотной кремнефтористоводородной кислотой отделенной от маточника, содерл ащего НзРО4 + CaHSiFe неотмытый содержащий 30% маточника CaSiFe 2Н20 примен етс дл разложени свежей порции апатита в трубчатой печи при 1200-1300° с образованием содержащего - 0,2%F2 кормового трикальцийфосфата. Выдел ющиес при этом фтористые газы вместе с такими же газами от кислотного разложени апатита абсорбируютс водой и возвращаютс в виде H2SiF6 в процесс на разложение апатита .The proposed method of simultaneously obtaining fertilizer monocarbium phosphate and feed tricalcium phosphate is that it is obtained in the production of monocalcium phosphate, while decomposing apatite concentrate with recycled hydrofluoric acid is separated from the mother liquor, containing HFD4 and CaHeHephracaphyephtheroma; portions of apatite in a tubular furnace at 1200-1300 ° with the formation of 0.2% F2-containing feed tricalcium phosphate. The fluorine gases produced in this case, together with the same gases, are absorbed by water from the acid decomposition of apatite and returned as H2SiF6 to the decomposition of apatite.
На чертеже изображена схема получени монокальцийфосфата и кормового трикальцийфосфата.The drawing shows a scheme for the preparation of monocalcium phosphate and feed tricalcium phosphate.
Предмет изобретени Subject invention
Способ получени трикальцийфосфата путем раложени апатита, отличающийс тем, что апатит подвергают разотожению при 1200-1300° полученным в производстве монокальцийфосфата осацком двухводного кремнефтористого кальци .A method for producing tricalcium phosphate by decomposing apatite, characterized in that apatite is subjected to dissolution at 1200-1300 ° obtained in the production of mono-calcium phosphate by precipitating calcium hydrofluoride calcium two-water.
