(S4) СПОСОБ ДВУХСТАДИЙНОГО ОБЖИГА ПИРИТА В РЕАКТОРАХ С ПСЕВДООЖИЖЕННЫМ СЛОЕМ(S4) METHOD OF TWO-STAGE BURNING OF Pyrite in reactors with a pseudo-liquefied layer
33
ригами. Это позвол ет удалить значительное количество мышь ка и свини.а, остатки которых могут быть подвергнуты дальнейшему восстановлению на ВТ .,рой стадии в атмосфере с восстанавливающими свойствами.rigs. This allows the removal of a significant amount of mouse and pigs. A, the remains of which can be subjected to further recovery at BT., A swarm of a stage in an atmosphere with reducing properties.
Необходимое содержание серы в обожженном материале после второй стадии обработки зависит от вида загружаемого в печь материала.и содержани в нем серы. The required sulfur content in the calcined material after the second stage of processing depends on the type of material fed into the furnace. And the sulfur content in it.
Обычно необходимо наличие 5% серы, предпочтительно 15% и не более 38% сфы в материале после обжига, причем последн цифра исходит из применени в качества сырь чистого пирита.Usually, 5% sulfur is required, preferably 15% and not more than 38% sf in the material after calcination, the latter figure being based on the use of pure pyrite as a raw material.
Обжиг осуществл ют в псевдоожиженном слое с подачей газа, содержащего свободный кислород, например воздух, смесь воздуха с двуокисью углерода или азота, или сернистый ангидрид, в количествах , соответствующих поддержанию указаннь х условий,. Кроме того, в реактор ввод т окислы и другие соединени железа до количества, при котором темпфатура не может более поддерживатьс на необходимом урозгз без подвода дополнительного тепла. Затем материалы загружают во второй реактор , в который добавл ют одно соединение железа типа окислп или сульфрзда.The calcination is carried out in a fluidized bed with a supply of gas containing free oxygen, such as air, a mixture of air with carbon dioxide or nitrogen dioxide, or sulfur dioxide, in quantities that meet the specified conditions. In addition, oxides and other iron compounds are introduced into the reactor to an amount at which the temperature can no longer be maintained at the required temperature without additional heat. The materials are then loaded into a second reactor, to which one iron compound is added, such as an oxidizer or sulfonate.
Подаваемый на первой или второйстадии материал может быть использован дл охлаждени реакторов .The material fed to the first or second stage can be used to cool the reactors.
Во втором реакторе обжиг ведут в услови х образовани магнетита.In the second reactor, the calcination is carried out under conditions of the formation of magnetite.
Способ провод т тшсим o asoMt что все количество входимого в систему воздуха находитс в определенном соотнощении с количеством загр жаемого сырь , в результатах чего можно поддерживать необходимое парциальное давление кислорода в газах обжига на второй стадии.The method is carried out by means of asoMt that the entire amount of air entering the system is in a certain proportion with the amount of raw material being loaded, the results of which can maintain the necessary partial pressure of oxygen in the second stage firing gases.
