Разработка режима флотации углей при использовании реагентов-вспенивателей различного химического состава и строения молекул

Abstract

В работе рассмотрено влияние действия реагентов-вспенивателей различного химического состава и строения молекул на разработку режима флотации углей, поступающих на коксование. Установлена наиболее высокая селективность процесса флотации при использовании в качестве реагента-вспенивателя ЭТС-40, что позволяет снизить зольность концентрата на 1,6% в отличие от использования других реагентов-вспенивателей. Пониженная зольность концентрата объясняется использованием в качестве реагентов-вспенивателей технических продуктов нефтехимии, содержащих в групповом химическом составе кремнийорганические соединения.

This article examines the effects of the operation of the reactants, foaming agents with different chemical composition and molecular structure on the development of coal flotation regime entering the coking. Set the highest selectivity of the flotation process using as reagent ETS-40 blowing agent that reduces the ash content at the outlet of 1.6% in contrast to the use of other reagents, blowing agents. The reduced ash content due to the use as reagents, industrial products of petrochemical blowing agent containing the group consisting of organosilicon compounds of the chemical.
