Изобретение относитс к подготовке фосфатного сырь к процессу электровозгонки фосфора и может быть применено в химической промышленности.The invention relates to the preparation of phosphate raw materials for the phosphorus electric sublimation process and can be applied in the chemical industry.
Цель изобретени - повьшение выхода продзпста и увеличение удельной производительности процесса.The purpose of the invention is to increase the output of the production and increase the specific productivity of the process.
Пример. Тонкоизмельченное фосфатное сьфье увлажн ют и окатывают на грантарели. Сырые окатыши смешивают с обожженными, имеющими температуру 200°С, в весовом соотношении 9:1. Температура смеси окатышей АОС, влажность 8,9%, термостойкость 300°С. Окатьшш загружают на колосниковую решетку, сушат и обжигают газообразным теплоносителем, подаваемым сверху через слой окатьш1ей. Сушку ведут при 300°С, а обжиг при 1180°С. Скорость подачи теплоносител во врем обжига 0,65 м/с. Удельна производительность процесса 0,52 т/м, выход продукта фракции плюс 5 мм 98,3%. Дес тую часть по весу обожженных окатьшгей возвращают на смешение с сырыми.Example. Finely divided phosphate is moistened and sprinkled on granterel. Raw pellets are mixed with baked, having a temperature of 200 ° C, in a weight ratio of 9: 1. The temperature of the mixture of pellets AOC, moisture 8.9%, heat resistance 300 ° C. They are loaded onto the grate, dried and burned with a gaseous coolant supplied from above through the layer of the grate. Drying is carried out at 300 ° C and firing at 1180 ° C. The flow rate of the coolant during firing 0.65 m / s. The specific productivity of the process is 0.52 t / m, the product yield of the fraction plus 5 mm is 98.3%. The tenth part by weight of the burnt oakshey is returned for mixing with the raw ones.
В таблице представлена зависимость показателей процесса от технологических параметров.The table shows the dependence of process indicators on technological parameters.
