Description
лоты при 90-95° С в течение 3 ч, полученную (Пульпу фильтруют п .кек промывают.lots at 90-95 ° C for 3 h, obtained (Pulp was filtered; the cake was washed.
Выход продукта составл ет 96 %.The product yield is 96%.
Степень извлечени железа в раствор составл ет 64 %.The degree of iron extraction into the solution is 64%.
Потери серной кислоты па св зывапне кальци в сульфат кальци в 3 раза меньше, чем в известном способе.The loss of sulfuric acid in calcium binding to calcium sulfate is 3 times less than in the known method.
Использование предлагаемого слособа получени раствора сульфата алюмини позвол ет уменьшить потерп серной кпслоты и расход известн ка при переработке золы; перерабатывать отходы энергетической промышленности в место цепиого гидрата окиси алюмини на сульфат алюмини дл использовани в Kai4ecTBe коагул нта дл очистки промышленных п бытовых вод и дл производства электролитического глинозема; улучшить саиитарно-гигиенические услови производства к его :влл ни-е на окружающ)ю среду.The use of the proposed aluminum sulphate solution production method makes it possible to reduce the sulfur dioxide content and lime consumption during the processing of ash; process waste from the power industry to a place of aluminum oxide hydrate on aluminum sulphate for use in Kai4ecTBe coagulant for purifying industrial and domestic water and for the production of electrolytic alumina; to improve the sanitary and hygienic conditions of production for its use: in the environment.
