Description
125°С и при этой температуре происходит разложение фосфата в течение 30 мин. Затем во вторую секцию подают еще 14,52 вес. ч. серной кислоты той же концентрации и продолжают перемешивание еще 25 мин. За это врем степень разложени апатита достигает 92%, в газовую фазу выдел етс 82% фтора. Пары воды и фтор улавливают в абсорбционной бащне. Пульпа при интенсивном перемещивании сохран ет хорошую подвижность, и ее пульповым насосом подают в барабанный гранул тор - сущилку, где происходит окончательна сушка и гранул ци продукта, а степень разложени апатита достигает 95%. Гранулированный продукт после барабанного гранул тора-сушилки классифицируют, охлаждают , нейтрализуют и передают на складирование .125 ° C and at this temperature the decomposition of phosphate occurs within 30 minutes. Then in the second section serves another 14.52 weight. including sulfuric acid of the same concentration and continue mixing for another 25 minutes. During this time, the degree of decomposition of apatite reaches 92%, 82% of fluorine is released into the gas phase. Water vapor and fluoride are trapped in the absorption bachne. With intensive movement, the pulp retains a good mobility, and its pulp pump is fed to a drum granulator, a nutcracker, where the final drying and granulation of the product takes place, and the degree of decomposition of apatite reaches 95%. The granulated product after the drum granulator torus dryer is classified, cooled, neutralized and transferred to storage.
Ориентировочный экономический эффект применительно к услови м Маардуского химкомбината (объем выпускаемого гранулированного суперфосфата составл ет 700 тыс. т/год в условных туках) составит за счет увеличени степени выделени и утилизации фтора при условии его переработки на фторидбифторид аммони 800000 руб/год.The estimated economic effect in relation to the conditions of the Maardu Chemical Plant (the volume of granulated superphosphate produced is 700 thousand tons / year in conditional tukas) due to an increase in the degree of emission and utilization of fluorine, provided it is processed to ammonium fluoride bifluoride 800,000 rubles / year.
