Description

Предлагаемый способ очистки поваренной соли от солей магни  и кали  основан на перекристаллизации Ла С/ в его насыщенных водных растворах с попеременным осаждением солей и Mg, при чем перва  осаждаетс  введением в раствор свежих количеств подлежащей очистке соли, а вторые - от прибавлени  известкового молока с получением, в виде отброса, раствора КС1 иThe proposed method for purification of sodium chloride salt from magnesium and potassium is based on the recrystallization of La C / in its saturated aqueous solutions with alternate precipitation of salts and Mg, at which the first is precipitated by the introduction of fresh amounts of salt to be purified into the solution, and the latter from , in the form of garbage, solution KC1 and

предлагаемый способ состоит в следующем . Высокую колонну с расширенным в виде колокола приемником внизу ее наполн ют насыщенным раствором чистой поваренной соли, нагретым до температуры, близкой к точке кипени . Эта температура сохран етс  во все врем  процесса. После этого сверху всыпают ровным слоем соль, подлежащую очистке, с таким расчетом, чтобы содержащиес  в ней соли кали  и магни  могли быThe proposed method consists in the following. The high column with a bell-extended receiver at the bottom of it is filled with a saturated solution of pure salt heated to a temperature close to the boiling point. This temperature is maintained throughout the process. After that, evenly pour the salt to be cleaned on top, so that the potassium and magnesium salts contained in it can

растворитьс  ранее того срока, который нужен дл  свободного падени  кристаллов сквозь весь раствор до дна приемника Затем на основании пробных титров раствора определ ют тот момент, когда раствор окажетс  насыщенным относительно магни . Тотчас прекращают введение новых количеств промываемой соли и весь выпавший в приемник осадок чистой Na Cl перенос т на центрофугу, где он осушаетс  от примеси раствора. Оставшийс  в колонне раствор смешивают затем с известковым молоком в соответствующей пропорции, в результате чего выпадает осадок Mg (ОН).,dissolve before the time required for the free fall of crystals through the entire solution to the bottom of the receiver. Then, on the basis of the test titers of the solution, the moment when the solution is saturated with respect to magnesium is determined. Immediately, the introduction of new quantities of the washed salt is stopped, and all the precipitate deposited in the receiver with pure NaCl is transferred to the centrifuge, where it is dried from the admixture of the solution. The solution remaining in the column is then mixed with the milk of lime in an appropriate proportion, resulting in a precipitate of Mg (OH).,

Вследствие сильной растворимости Са С4, остаток раствора может быть использован дл  промывки новых количеств соли, вплоть до получени  растворов, насыщенных относительно Са CL или КС1, представл ющих отброс. Предмет патента. Способ очистки поваренной соли от солей магни  и кали , отличающийс  тем, что мелкую поваренную - соль пропускают сквозь высокий слой насыщенного раствора чистой поваренной соли при температуре, близкипени  этого кой к температуре раствора.Due to the strong solubility of Ca C4, the remainder of the solution can be used to wash new amounts of salt, up to and including solutions saturated with Ca CL or KC1, representing garbage. The subject of the patent. The method of purification of table salt from magnesium and potassium salts, characterized in that small table salt is passed through a high layer of a saturated solution of pure table salt at a temperature that is close to the temperature of the solution.
