Description
Известен способ очистки плава сернистого натри от нерастворимых примесей, заключаюпшйс в том, что плав сернистого патри раствор ют в воде и к нему добавл ют раствор сернокислого цинка с последующим осаждением нерастворимых примесей.A known method of purifying sodium sulfate from insoluble impurities involves the fact that the melted sodium sulfide is dissolved in water and a solution of zinc sulfate is added to it, followed by precipitation of insoluble impurities.
Предложенный способ отличаетс от известного способа тем, что непосредственно в плав сернистого натри ввод т флюсы, например окись кальци и окись железа. Таким образом значительно упрощают процесс с наиболее полным отделением нерастворимых примесей .The proposed method differs from the known method in that fluxes, such as calcium oxide and iron oxide, are introduced directly into the smelt of sodium sulphide. Thus greatly simplify the process with the most complete separation of insoluble impurities.
Пример. В обогреваемую (при 1200°С) толстостенную банку из нержавеющей стали (1Х18П9Т) емкостью 8 кг заливают жидкий плав сернистого натри из шахтной печи. Добавл ют при перемешивании флюсы 380 гExample. In heated (at 1200 ° С) thick-walled can of stainless steel (1Х18П9Т) with a capacity of 8 kg, liquid sodium sulphide melt is poured from the shaft furnace. 380 g added with stirring
окиси кальци , 140 г закисного железа. При этом плав разлсижаетс , шлаки собирают в нижней части банки. В результате очистки полученный плав сернистого натри имеет следующий состав, fi/o: 80 NaoS; 0,5 нерастворимый остаток; 0,6 Fe.calcium oxide, 140 g of ferrous oxide. In this case, the melt decomposes, slags are collected in the lower part of the jar. As a result of the purification, the resulting sodium sulfate melt has the following composition, fi / o: 80 NaoS; 0.5 insoluble residue; 0.6 Fe.
Предмет изобретени Subject invention
Способ очистки плава сернистого натри путем осаждени нерастворимых примесей в присутствии неорганических добавок, отличающийс тем, что, с целью упрощени процесса и более полного отделени нерастворимых примесей, в качестве неорганических добавок примен ют флюсы, например окись кальци и окись железа, которые ввод т непосредственно в плав сернистого натри .A method of purifying sodium sulphate by precipitating insoluble impurities in the presence of inorganic additives, characterized in that, in order to simplify the process and more completely separate insoluble impurities, fluxes, such as calcium oxide and iron oxide, are used as inorganic additives directly melt sodium sulfide.
