Description
(54) СПОСОБ БРИКЕТИРОВАНИЯ СУЛЬФАТА НАТРИЯ(54) METHOD FOR BRIQUETTING SODIUM SULPHATE
вращени сульфата натри в сульфид на 3,5- 6,3%, производительность шахтной печи на 10-15%.rotation of sodium sulfate to sulfide by 3.5-6.3%, the productivity of a shaft furnace by 10-15%.
Пример. Порошкообразный сульфат натри с исходной влажностью 3% поступает в бункер, откуда лотковым нитателем, нодают на транспортерную ленту, далее элеватором в установку КС, где интенсивно перемешиваетс воздушным потоком. На транспортерную ленту до элеватора из дополнительного бункера тарельчатым питателем подают полугидрат сульфата кальци . Разр жение в установке КС 3 мм вод. ст., перепад давлени 750 мм вод. ст., расход воздуха 7500 , температура воздуха 31 °С.Example. Sodium sulfate powder with an initial moisture content of 3% enters the bunker, from where it is put on a conveyor belt with a lot of thread, then goes to the CS plant by an elevator, where it is vigorously stirred by air flow. Calcium sulfate hemihydrate is fed to the conveyor belt to the elevator from an additional bunker with a plate feeder. Discharge in the installation of KS 3 mm water. Art., pressure drop 750 mm water. Art., air flow 7500, air temperature 31 ° C.
Над «кип шим слоем распыл етс техническа вода, расход которой 735 л/ч, а температура 18°С. Увлажненную и тщательно перемешанную массу подают на два вальцевых пресса с давлением прессовани 150- 250 КГС/СМ2.Technical water is sprayed above the boiling layer, the flow rate is 735 l / h and the temperature is 18 ° C. A moistened and thoroughly mixed mass is fed to two roller presses with a pressing pressure of 150-250 KGS / CM2.
Выход брикетов весом 650 г составл ет 95%.A yield of 650 g briquettes is 95%.
Состав брикета, %: NaaSOi 82,2; И.О. 0,9; CaSO4 6,6; NaCl 0,1; Н20 9,2; СгОз 0,4; HzSOThe composition of the briquette,%: NaaSOi 82.2; AND ABOUT. 0.9; CaSO4 6.6; NaCl 0.1; H20 9.2; SgOz 0,4; HzSO
0,4. Брикет разрушаетс при нагрузке 133 кгс/см. После восстановительной плавки в услови х шахтной печи печной плав имеет состав, %: КазЗ 66,3; NaaSgOg 3,7; Na2SO4 Ыа2СОз отсутствует, CaSO4 5,1; нерастворимый остаток 13,9. Степень превращени сульфата натри в сульфид - 93%.0.4. The briquette is destroyed under a load of 133 kgf / cm. After reduction smelting in the conditions of a shaft furnace, the furnace melt has the composition,%: KazZ 66.3; NaaSgOg 3.7; Na2SO4 Na2COz is absent, CaSO4 5.1; insoluble residue 13.9. The conversion of sodium sulfate to sulfide is 93%.
