Description
Изобретение относитс к области получени соединений бари .The invention relates to the field of producing barium compounds.
Известный периодический способ получени хлористого бари заключаетс в спекании баритового концентрата с восстановителем и хлористым кальцием в течение 4-5 час. При этом, полученный плав хлористого бари сливают , охлаждают, измельчают и выщелачиЕ-ают .The known periodic method for producing barium chloride is to sinter barite concentrate with reducing agent and calcium chloride for 4-5 hours. At the same time, the resulting melt of barium chloride is poured, cooled, crushed and leached.
С целью непрерывного осуществлени процесса , предлагаетс смесь баритового концентрата и восстановител предварительно прокаливать при 900-1200°С, а весовое отношение баритового концентрата к восстановителю брать пор дка 3:1. Предварительное прокаливание можно проводить в одной барабанной вращающейс печи.In order to carry out the process continuously, a mixture of barite concentrate and reductant is preliminarily calcined at 900-1200 ° C, and the weight ratio of barite concentrate to reducing agent is taken in the order of 3: 1. Pre-calcination can be carried out in a single drum rotary kiln.
Чтобы предотвратить спекание плава сернистого бари с футеровкой печи при предварительном прокаливании, в шихту ввод т 15- 20% хлористого кальци . С той же целью при введении в печь всего хлористого кальци ввод т дополнительно 10-15% восстановител или баритового концентрата. При врем проведени всего процесса восстановлени около 2 час.To prevent sintering of the sulphurous barium melt with the furnace lining during preliminary calcination, 15-20% calcium chloride is introduced into the mixture. For the same purpose, with the introduction of total calcium chloride into the furnace, an additional 10–15% of the reducing agent or barite concentrate is introduced. When the entire recovery process is performed, it takes about 2 hours.
гранулируют на чашечном гранул торе. Далее щихту в виде гранул весом 143 лг и 7,5 кг хлористого кальци , содержащего 73% основного вещества, загружают в печь, температуру в которой поддерживают пор дка 1100°С. По мере продвижени плава в печи происходит восстановление баритового концентрата . Через 50 мин в среднюю часть печи подают 70 кг хлористого кальци , содержащего 73% основного вещества, и 10 кг баритового концентрата. Температуру в печи поддерживают 1000°С.granulated on a pan granulator. Next, blended granules weighing 143 lg and 7.5 kg of calcium chloride, containing 73% of the basic substance, are loaded into a furnace, in which the temperature is maintained at about 1100 ° C. As the melt advances in the furnace, barite concentrate is restored. After 50 minutes, 70 kg of calcium chloride containing 73% of the main substance and 10 kg of barite concentrate are fed to the middle part of the furnace. The temperature in the furnace support 1000 ° C.
Состав полученного плава: Bad, - 92 кг, СаСЬ, - 4 кг, CaS - 20 кг С - 3 кг, КаОз, SiOj и пр. - 9 кг.The composition of the resulting melt: Bad, - 92 kg, CAC, - 4 kg, CaS - 20 kg C - 3 kg, KaOz, SiOj, etc. - 9 kg.
Врем проведени всего процесса 125 лшп.The duration of the process is 125 lshp.
