Description
Известны способы снижени влажности цементных сырьевых шламов при помощи различных реагентов-разжижителей органического и минерального происхождени : с льфитно-спиртовой барды, дубильного экстракта, канализационных щелоков, щелочных торф ных выт жек, растворимого стекла и др.There are known methods for reducing the moisture content of cement raw sludges with the help of various organic and mineral diluents: from alcohol-alcohol stillage, tanning extract, sewage liquor, alkaline peat extracts, soluble glass, etc.
Предлагаемый способ позвол ет использовать отходы промыщленности дл производства разжил ител и тем самым расширить ассортимент недефицитпых реагентов цл снижени влажности шламов.The proposed method allows the use of industrial wastes for the production of wastewater and thereby expanding the range of non-deficient chemicals for reducing the moisture content of sludge.
В описываемом способе в качестве разжижител цементных сырьевых шламов примен етс щелочной лигнин, получаемый путем нагревани отхода гидролизной промышленности - лигнина со шелочью. Щелочной лигнин вводитс при помоле в цементные сырьевые щламы в количестве от 0,1 до 1% по весу.In the described method, alkaline lignin is used as a diluent for cement raw sludges, which is obtained by heating the waste of the hydrolysis industry - lignin with silk. Alkaline lignin is introduced by grinding into cement raw materials in an amount of from 0.1 to 1% by weight.
Применение щелочного лигнина в качестве разжижител в указанных количествах позвол ет снизить влажность шлама на 2,5-7,7°о, не измен при этом его текучести.The use of alkaline lignin as a diluent in the indicated amounts allows to reduce the moisture of the sludge by 2.5-7.7 ° o without changing its flowability.
Предмет изобретени Subject invention
Снособ снижени влажности сырьевых цементных шламов с помошью разжижителей органического и минерального происхождени , о тличающийс тем, что, с целью расщирени ассортимента реагентов дл снижени влажности щламов, при помоле сырьевых цементных в них ввод т в количестве от 0,1 до 1% по весу щелочной лигнин, подучаемьш путем (агревани отхода гидролизной промьн ленности- - лигнина сощелочью.The method for reducing the moisture content of raw cement slurries with the help of organic and mineral diluents, is characterized in that, in order to expand the assortment of reagents to reduce the moisture of the slurry, when grinding the raw cement, they are introduced in an amount of from 0.1 to 1% by weight alkaline lignin produced by (heating of the waste by hydrolysis industry - lignin with a base.
