Description

Известен способ получени  суперфосфата путем обработки фосфата серной и сол ной кислотами.A method of producing superphosphate is known by treating phosphate with sulfuric and hydrochloric acids.

Описываел ый способ по сравнению с известными упрощает технологию и обеспечивает получение продукта в гранулированном виде.The described method, in comparison with the known ones, simplifies the technology and ensures the preparation of the product in granular form.

Дл  этого фосфат обрабатывают отдельно в смесител х серной и сол ной кислотами, затем приготовленную пульпу и раствор, полученный от обработки фосфата сол ной кислотой, смешивают друг с другом, добавл ют готовый суперфосфат и сушат, отогнанную при этом сол ную кислоту возвраш,ают в цикл.For this, the phosphate is treated separately in mixers with sulfuric and hydrochloric acids, then the prepared pulp and the solution obtained from the treatment of phosphate with hydrochloric acid are mixed with each other, the finished superphosphate is added and dried, the hydrochloric acid is distilled off during this process. cycle.

Способ осуществл ют следующим образом.The method is carried out as follows.

Фосфат обрабатываетс  в смесителе серной кислотой. Полученную пульпу смешивают с раствором фосфата в крепкой .сол ной кислоте, приготовленной в другом смесителе. К смеси добавл ют готовый сртерфосфат в количестве, потребном дл  образовани  (после перемешивани ) сыпучгй массы, котора  затем подвергаетс  сущке. В процессе сушки масса гранулируетс .The phosphate is treated in the mixer with sulfuric acid. The resulting pulp is mixed with a phosphate solution in strong hydrochloric acid prepared in another mixer. The finished srphosphate is added to the mixture in the amount required to form (after stirring) a granular mass, which is then subjected to a substance. During the drying process, the mass is granulated.

Выдел юща с  в процессе сушки сол на  кислота улавливаетс  суспензией фосфата (путем хемосорбции) и раствор ет суспендированный фосфат. Полученный раствор фосфата в крепкой сол ной кислоте возвращаетс  в цикл дл  смешени  с иовым количеством смеси фосфата в серной кислоте. Таким образом, сол на  кислота все врем  циркулирует в процессе. В готовом продукте, полученном в гранулированном виде, сол на  кислота практически отсутствует.The hydrochloric acid released during the drying process is captured by the phosphate suspension (by chemisorption) and dissolves the suspended phosphate. The resulting phosphate solution in strong hydrochloric acid is recycled for mixing with the total amount of the phosphate mixture in sulfuric acid. Thus, hydrochloric acid circulates in the process all the time. In the finished product obtained in granular form, hydrochloric acid is practically absent.

При проведении цроцеоса не требуютс  нейтрализующие добавки, так как после сушки гранулированный суперфосфат содержит требуемое по стандарту количество свободной п тиокиси фосфора. Сточные воды отсутствуют, вследствие того, что во врем  сушки сол на  кислота циркулирует в процессе- Расход серной кислоты на тонну усво емой п ти№ 119190- 2 -Neutralizing additives are not required when performing croceos, since after drying granulated superphosphate contains the required amount of free phosphorus pentoxide. There is no waste water due to the fact that during the drying the hydrochloric acid circulates in the process. The consumption of sulfuric acid per ton of digestible pepper is 119,190-2 -

окиси фосфора в готовом продукте ниже расхода при получении суперфосфата известным cn9fo6oM.phosphorus oxide in the finished product below the flow rate in obtaining superphosphate known cn9fo6oM.

Предмет изобретени Subject invention

Способ получени  суперфосфата путем обработки фосфата серной и сол ной кислотами, отличающийс  тем, что, с целью упрощени  технологического процесса и получени  продукта в гранулированном виде, фосфат обрабатывают отдельно в смесител х серной кислотой и сол ной , затем приготовленную пульпу и раствор, полученный от обработки фосфата сол ной кислотой, смешивают друг с другом, добавл ют готовый суперфосфат и сушат, отогнанную при этом сол ную кислоту возвращают в цикл.The method of producing superphosphate by treating phosphate with sulfuric and hydrochloric acids, characterized in that, in order to simplify the process and obtain the product in granular form, the phosphate is treated separately in mixers with sulfuric acid and hydrochloric, then the prepared pulp and solution obtained from processing phosphate with hydrochloric acid, mixed with each other, the finished superphosphate is added and dried, and the hydrochloric acid distilled at the same time is recycled.
