Abstract
1. Способ получения угольных брикетов, включающий в себя технологические стадии: отсев угольной шихты от крупной мелочи, ее смешение со связующим - водным раствором флокулянта с примесью ПАВ, брикетирование, сушку, затаривание полученных брикетов, отличающийся тем, что в качестве основного компонента связующего предложен водный раствор флокулянта на основе ПАА с его расходом на изготовление брикета 0,2-0,3% от массы угольной шихты. ! 2. Способ по п.1, отличающийся тем, что в качестве дополнительного компонента в водный раствор ПАА введена добавка неионогенного ПАВ-смеси простых полиэфиров на основе полипропиленгликолей переменного состава, содержащей ди-, три- и полипропиленгликоли, являющиеся отходом стадии ректификации в производстве пропиленгликоля. !3. Способ по п.1, отличающийся тем, что расход ПАВ составляет 0,4-0,6% от массы угля. 1. A method for producing coal briquettes, which includes technological stages: screening the coal charge from small fines, mixing it with a binder - an aqueous solution of a flocculant mixed with surfactant, briquetting, drying, packing the obtained briquettes, characterized in that it is proposed as the main component of the binder an aqueous solution of a flocculant based on PAA with its consumption for the manufacture of briquettes 0.2-0.3% by weight of the coal charge. ! 2. The method according to claim 1, characterized in that, as an additional component, an additive of a nonionic surfactant mixture of polyethers based on polypropylene glycols of variable composition containing di-, tri- and polypropylene glycols, which are a waste of the rectification stage in the production of propylene glycol, is added to the aqueous PAA solution . ! 3. The method according to claim 1, characterized in that the consumption of surfactant is 0.4-0.6% by weight of coal.
