Description
Способ осветлени пульп глиноземного производства с применением .флокул нтов, например муки, известен.A method for clarifying alumina production pulps using flocks, such as flour, is known.
Онисываемый способ осветлени , в отличие от известного, вл етс более эффективным и не требует применени муки (пищевого продукта ) .The clarified clarification method, in contrast to the known method, is more efficient and does not require the use of flour (foodstuff).
Особенность способа заключаетс в том, что в качестве флокул нта примен ют синтетический реагент АМФ-168, представл ющнй собой воднорастворимые высокомолекул рные соединени полиакриламидного типа.The peculiarity of the method lies in the fact that flocculant is used synthetic reagent AMP-168, which is a water-soluble high molecular weight polyacrylamide compound.
При осветлении, например красного шлама, берут синтетический реагент в количестве 50 г/г отвеса сухого шлама (вместо 1,5 кг муки).When clarifying, for example, red mud, take a synthetic reagent in the amount of 50 g / g of dry sludge plumb (instead of 1.5 kg of flour).
Эффективность способа по сн етс следующим примером.The effectiveness of the method is illustrated by the following example.
Дл осветлени вз та пульпа крас1 ого шлама глиноземного производства уд. в. 1,256 и, содержаща АЬОз-120 г/.г, NajO (общее) - 140 , NaaO каустической-126 г/л.To clarify the recovered pulp of the beautiful sludge from alumina production beats. at. 1,256 and, containing АООз-120 g / .г, NajO (total) - 140, NaaO caustic-126 g / l.
Содержание красного шлама в пульпе составл ет 35 гДг.The red mud content of the pulp is 35 gDg.
Проведенные опыты по осветлению шламов синтетическим реагентом АМФ-168 (из расчета 50 г/г) и высококачественной мукой (из расчета 1,5 кг/г) при температуре 90° показали, что предлагаемый флокул нт эффективнее известного и расход его меньше.Experiments on the clarification of sludge with synthetic reagent AMF-168 (at the rate of 50 g / g) and high-quality flour (at the rate of 1.5 kg / g) at a temperature of 90 ° showed that the proposed flocculant is more efficient than the known and its consumption is less.
