Изобретение относитс  к способам получени  эпсомита (кристаллогидрата сульфата магни  MpSO4-71 20) и может быть использовано в химической промышленности в производстве добавок дл  цементов, высококачественной окиси магни , магнезиального удобрени  и др.The invention relates to methods for producing epsomite (magnesium sulfate crystalline MpSO4-71 20) and can be used in the chemical industry in the production of additives for cements, high-quality magnesium oxide, magnesia fertilizer, etc.

Известен способ получени  эпсомита из природного сульфатно-хлормагниевого сырь  - морской воды - путем ее упаривани  до концентрации MgSO4 - 9,1%, MgCU - 14,7%, NaCl -9,8% и охлаждени  упаренного раствора до -5°С с последующим отделением кристаллов.A method is known for producing epsomite from natural sulfate-chloromagnesium raw material — sea water — by evaporation to a concentration of MgSO4 — 9.1%, MgCU — 14.7%, NaCl —9.8%, and cooling the evaporated solution to -5 ° C, followed by separation of crystals.

Недостаток этого способа - значительные энертозатраты на упаривание морокой воды.The disadvantage of this method is significant energy consumption for evaporation of sea water.

Дл  расширени  сырьевой базы и снижени  энергозатрат предлагаетс  мирабилит смешивать с 23-26%-пым pacTBOipoM хлористого магпи  в весовом соотношении 1:2-4,5 и выдел ть кристаллы из полученной суспензии.In order to expand the raw material base and reduce energy consumption, it is suggested that mirabilite be mixed with 23-26% pacTBOipoM chloride magpie in a weight ratio of 1: 2-4.5 and isolate the crystals from the resulting suspension.

Пример 1. К 2,4 25%-кого хлор.магниевого раствора добавл ют 1,0 кг мирабилита (4:1,7% Na2SO4) при 20°С и интенсивно перемешивают в теплоизолированном реакторе. Через 4 мин из суспензии отдел ют 0,37 кгExample 1. To a 2.4 to 25% chlorine magnesium solution, add 1.0 kg of mirabilite (4: 1.7% Na2SO4) at 20 ° C and mix vigorously in a thermally insulated reactor. After 4 minutes, 0.37 kg of suspension is separated.

твердой фазы, по составу соответствующей эпсомиту - семиводному сульфату магни .solid phase, according to the composition of the Epsomite - magnesium chloride sulphate.

Пример 2. При той же тем1пе ратуре смешивают 1 кг мирабилита и 3,2 кг 26%-ного раствора хлористого магни . После 5 мин перемешивани  получают 0,45 кг эпсомита.Example 2. At the same temperature, 1 kg of mirabilite and 3.2 kg of a 26% magnesium chloride solution are mixed. After 5 minutes of stirring, 0.45 kg of epsomite is obtained.

Пример 3. При тех же температурпых услови х смешивают 1 кг мирабилита и 4,3 кг 23%-ного раствора хлористого магни , получают 0,52 кг эпсомита.Example 3. Under the same temperature conditions, 1 kg of mirabilite and 4.3 kg of a 23% magnesium chloride solution are mixed; 0.52 kg of epsomite is obtained.

Таким образом получают технический эпсомит из нового вида сырь , что позвол ет вести Процесс с меньшими энергетическими затратами .In this way, a technical epsomite is obtained from a new type of raw material, which allows the Process to be conducted with lower energy costs.

По сравнению с известным способом энергетические затраты снижаютс  в 3-4 раз.In comparison with the known method, energy costs are reduced by 3-4 times.

Предмет изобретени Subject invention

Способ получени  зпсомита из сульфатнохлормагниевого сырь , отличаю1цийс  тем, что. с целью расширени  сырьевой базы, мира билит смешивают с 23-26%-ным раствором хлористого магни  в весовом соотношенииThe method of obtaining zpsomita from sulphate-chloromagnesium raw material differs by the fact that. In order to expand the raw material base, Bilit is mixed with a 23-26% solution of magnesium chloride in a weight ratio

1 :2-4,5 и из полученной суспензии выдел ют кристаллы.1: 2-4.5, and crystals were separated from the resulting suspension.
