Изобретение относитс к области борьбы с пылью в процессах получени пылевидного торфа, используемого в энергетике, микробиоло гии, сельском и других област х народного хоз йства . Известен состав дл пылеподавленн , содер жащий 0,00005-1,0 вес.% водного раствора натриевой соли эквнмол рной смеси моно- М дйцетилфосфзтов общей формулы (Яб PO ONa+C g Н jOP(O) (ONa) 11. Недостатком этого состава вл етс низка эффективность пы елодавлени . Наиболее близким по технической суииюсти и достигаемому результату к предлагаемому вл етс состав дл пыле1К давлеш1 , включающий воду и 0,00001-1,0 вес.% смачивател на основе полиглицеркдов общей формулы (СН СН-СН О)в ,где R -фракци синте0 тнческих жирных кислот , {2, Недостатком состава вл етс слаба актив иость к подавленто торф ной пыли, особенно ее мелких частиц (50 мкм и менее). Цель изобретени - повыиюок эффективности пылеподавлени . Поставленна цель достигаетс тем, что состав дл подавлени торф ной пыли на основе воды и поверхностно-активного вещества содержит , в качестве поверхностно-активного вещества, алкилсульфонат натри общей формулы , где R - алкил с длиной цепи С Q при следующих соотношешс х компонентов , вес.%: Алкилсульфонат натри OjO 1-0,1 ВодаОстальное Выпускаемый промыишенностью легкодоступный алкильсульфонат натри (ОСТ 6-01-32-77 ) представл ет собой жидкий или пастообразный продукт, раствори1ш 1й в воде, не вьшадаюищй из разбавленных растворов минеральных кислот и щелочей. Состав дл пыледавлени готов т простым растворением алкнлсульфоната натри в воде. Пример. Эффект усилени вод ного пылеподавлени алкильсульфонатом оценивают путем пленочной флотации по времени осаждени торфмюй пыли с размером частиц 50 мкмThe invention relates to the field of dust control in the processes of obtaining pulverized peat used in power engineering, microbiology, agriculture, and other areas of the national economy. A composition for dust suppression is known, containing 0.00005-1.0% by weight of an aqueous solution of the sodium salt of an equimolar mixture of mono-M dimethyl phosphosts of the general formula (Yab PO ONa + Cg H jOP (O) (ONa) 11. The disadvantage of this composition is is the lowest dusting efficiency. The closest in terms of technical resolution and the achieved result to the proposed is the composition for dust pressure 1, including water and 0.00001-1.0 wt.% wetter based on polyglycers of the general formula (CH CH-CH O) in, where R is the fraction of synthetic fatty acids, {2, The disadvantage of the composition is weak and the activity to suppress peat dust, especially its fine particles (50 µm or less). The purpose of the invention is to increase the efficiency of dust suppression. The goal is achieved by the fact that the composition for suppressing peat dust based on water and surfactant contains as a surfactant, sodium alkyl sulfonate of the general formula, where R is alkyl with a chain length Q Q in the following ratios, wt%: Alkyl sulfonate sodium OjO 1-0,1 WaterOthers Available in easily available alkyl sulfate on three (OST 6-01-32-77) is a liquid or pasty product, dissolved in water, not from dilute solutions of mineral acids and alkalis. The dusting composition is prepared by simply dissolving sodium alkynesulfonate in water. Example. The effect of enhancing water dust suppression with alkyl sulfonate is evaluated by film flotation based on the deposition time of peat dust with a particle size of 50 µm.
и менее из imsHHHoro торфа Нелванского месторождени . Навеску пыли 0,1 г высьшают на новерх ость 200 г вбды или состава, помещенных в 250 мл химические стаканы и по времени осаждени торф ной пыли суд т об эффективности состава. Чем меньше врем полного осаждени торф но пыли, тем эффективнее состав.and less from imsHHHoro peat from the Nelvansky deposit. A portion of 0.1 g of dust is dried to the tip of 200 g of budding or composition placed in 250 ml beakers, and the composition efficiency is judged by the time of deposition of peat dust. The shorter the time for complete precipitation of peat but dust, the more effective the composition.
