Abstract
Description
Изобретение относится к составам сырьевых смесей, используемых в производстве цемента.The invention relates to compositions of raw mixtures used in the production of cement.
Известны сырьевые смеси, включающие глинистый компонент и известняк [1].Raw mixtures are known, including a clay component and limestone [1].
Известна сырьевая смесь, содержащая, мас.%: глинистый компонент 10,0-80,0; пиритные огарки 0,5-3,0; шлам нейтрализации сточных вод производства фосфорной кислоты 0,5-4,0; карбонат магния 0,5-5,0; фосфогипс 0,3-3,0; пыль электрофильтров вращающихся печей цементной промышленности 1,0-10,0; известняк - остальное [2].Known raw mix containing, wt.%: Clay component 10.0-80.0; pyrite cinders 0.5-3.0; sludge neutralization of wastewater production of phosphoric acid 0.5-4.0; magnesium carbonate 0.5-5.0; phosphogypsum 0.3-3.0; dust of electrostatic precipitators of rotary kilns of the cement industry 1,0-10,0; limestone - the rest [2].
Цель изобретения - повышение прочности цемента.The purpose of the invention is to increase the strength of cement.
Цель достигается тем, что в состав сырьевой смеси дополнительно вводят сульфитно-спиртовую барду и шлам нейтрализации сточных вод производства серной кислоты, при следующем соотношении компонентов, мас.%: глинистый компонент 20,0-30,0; пиритные огарки 1,0-2,0; шлам нейтрализации сточных вод производства фосфорной кислоты 3,0-4,0; карбонат магния 3,0-4,0; фосфогипс 1,0-2,0; пыль электрофильтров вращающихся печей цементной промышленности 5,0-10,0; сульфитно-спиртовая барда 0,1-0,2; шлам нейтрализации сточных вод производства - серной кислоты 4,0-5,0; известняк - остальное.The goal is achieved by the fact that sulfite-alcohol stillage and a slurry of neutralizing wastewater from sulfuric acid production are additionally introduced into the composition of the raw material mixture, in the following ratio of components, wt.%: Clay component 20.0-30.0; pyrite cinder 1.0-2.0; phosphoric acid production wastewater neutralization sludge 3.0-4.0; magnesium carbonate 3.0-4.0; phosphogypsum 1.0-2.0; dust of electrostatic precipitators of rotary kilns of the cement industry 5.0-10.0; sulphite-alcohol bard 0.1-0.2; sludge neutralization of wastewater production - sulfuric acid 4.0-5.0; limestone - the rest.
В таблице приведены составы сырьевой смеси и прочность цемента.The table shows the composition of the raw mix and the strength of cement.
В качестве глинистого компонента может быть использован бентонит, каолин и т.п. Шлам нейтрализации сточных вод производства фосфорной кислоты на 80-98% состоит из двуводного сульфата кальция, остальное - примеси фосфатов, фторидов, кремнезема. Шлам нейтрализации сточных вод производства серной кислоты имеет состав, мас.%: сера 71-73, известь 0,5-0,7, опока 15-17, шпаты 1-3, каолин остальное.As the clay component, bentonite, kaolin, and the like can be used. The slurry of neutralizing wastewater from the production of phosphoric acid is 80-98% composed of dibasic calcium sulfate, the rest is impurities of phosphates, fluorides, and silica. The slurry of neutralizing wastewater from the production of sulfuric acid has a composition, wt.%: Sulfur 71-73, lime 0.5-0.7, flask 15-17, spars 1-3, kaolin the rest.
