Description

Существующие способы переработки спеков не позвол ют быстр отдел ть шлам от крепких растворов дл  нск.лочсин  протекани  вторичных реакций за счет разложени  двухкальциевого силиката и св занных с НИМИ потерь глинозема и шелочи.Existing methods for the processing of cakes do not allow for quick separation of sludge from strong solutions for the treatment of secondary reactions due to the decomposition of dicalcium silicate and the loss of alumina and shells associated with THEM.

ПрехТ;лагаемый способ получени  глинозема по параллельно комбинированной схеме «Байер-Спекание отличаетс  -от известных тем, что агитационное выщелачивание спека и отделение шлама от растворов спековой пульпы -ведут в слабых растворах промывной системы ветви Байера, а полученные окончательные концентрированные растворы перерабатывают по схеме Байера.PrechT; The Bayer Sintering parallel method for producing alumina differs from that known as the agitation leaching of the cake and the separation of the sludge from the solutions of the slurry pulp in a weak solution of the washing system of the Bayer branch, and the final concentrated solutions are processed according to the Bayer scheme .

Этот способ исключает операцию обескремнивани , уменьшает потери глинозема и щелочи, -не требует переделов дл  переработки спекательной пульпы и обеспечивает в услови х одного алюминиевого предпри ти  годовую экономию около 3 млн. руб.This method eliminates the operation of desiliconization, reduces the loss of alumina and alkali, does not require reworking for the processing of sintering pulp and provides, under the conditions of an aluminum plant, annual savings of about 3 million rubles.

Процесс ведут следующим образом. Спекание дл  агитационного выщелачивани  спека провод т в мельницах по замкнутому циклу с классификатором. Дл  вышелачивани  спека используют оборотный раствор, составленный из промывных вод от вторых промывателей ветви Байера и маточного раствора с декомпозиции. Концентрацию обратного раствора подбирают в зависимости от соотношени  потоков ветвей . Байера и спекани . Полученную спекательную пульпу без промежуточных емкостей откачивают в гидрос-месители, где она смешиваетс  в момент поступлени  с промывных вод вторых промыв телей и концентраци  ее доводитс  до концентраций, соответствующих первым промывател м ветви Байера, т. е. 35-40 г1л Na2O общ.The process is as follows. Sintering for agitation leaching of the sinter is carried out in a mill in a closed loop with a classifier. To leach the cake, a circulating solution is used consisting of wash water from the second washers of the Bayer branch and the mother liquor with decomposition. The concentration of the inverse solution is selected depending on the ratio of the flows of the branches. Bayer and speckle. The obtained sintering pulp without intermediate tanks is pumped out into hydro-kneaders, where it is mixed at the time of the second washers coming from the washings and its concentration is brought to concentrations corresponding to the first Bayer washers, i.e. 35-40 g1 of Na2O total.
