Изобретение относитс к горной промышленности и может быть использовано дли улавливани пыли.The invention relates to the mining industry and can be used to capture dust.
Известен способ приготовлени смеси дл улавливани пыли, основан 1ый на непoльзoE aнии порошкообразных гигроскопических солей и смачивающих добавок 1|,A known method of preparing a mixture for trapping dust is based on the first use of powdered hygroscopic salts and wetting additives 1 |,
Недостаток известного способа заключаетс в том,, что при использовании получаемой смеси в рудничном воздухе по вл етс солева пыль.A disadvantage of the known method is that when using the resulting mixture in the mine air salt dust appears.
Известен другой способ приготовлени смеси дл улавливани пыли, основанньгй на использовании порошкообразных гигроскопических солей, смачивающих агентов и инертных добавок 2.There is another method of preparing a mixture for trapping dust, based on the use of hygroscopic powdered salts, wetting agents and inert additives 2.
Однако при этом способе приготовлени расходуетс большое количество гигроскопических солей, а эффективность пылеулавливак дей смеси низка.However, this method of preparation consumes a large amount of hygroscopic salts, and the efficiency of dust collection of the mixture is low.
Цель изобретени - повышение эффективности пылеулавливающей смеси, снижение расхода гигроскопических солей и исключение образовани солевой пыли в рудиичной атмосфере,The purpose of the invention is to increase the efficiency of the dust collection mixture, reduce the consumption of hygroscopic salts and eliminate the formation of salt dust in the rudium atmosphere,
Поставленна цель достигаетс тем, что в гигроскопическую соль перед применением при перемешивании ввод т тонкодисперсную воду в количестве 1-2 О вес. %, преимущественно 6 вес. %, причем количество конечного продукта относительно гигроскопической сол принимают в пределах 74-90 вес.%, преимущественно 8О85 вес.%, а при введении в смесь инертных добавок отношение количества гигроскопической соли, к количеству воды принимают при весовом соотнсмиении от 74: 26 до 9О : 1О, преимущественно 8О:2О.The goal is achieved by introducing fine water in an amount of 1-2 O before the application with a hygroscopic salt. %, mostly 6 wt. %, with the amount of the final product relative to the hygroscopic salt being in the range of 74-90% by weight, mainly 885% by weight, and when inert additives are added to the mixture, the ratio of the amount of the hygroscopic salt to the amount of water is taken at a weight ratio of 74: 26 to 9O : 1O, mainly 8O: 2O.
Способ осуществл етс следующим образом .The method is carried out as follows.
Перед нанесением сло гигроскопической соли ввод т тонкодисперсную воду в количестве от 1 до 2О вес.%, преимущественно 6 вес.%, по отношению к количеству гигроскопической соли. Если используютс не такие чистые гигроскопические соли, как, наприь ер, хлористый кальций, хлористьй магний или смесь этих солей, а их смесь с инертными веществами, среди которых могут быть измельченные вBefore applying a layer of hygroscopic salt, fine water is introduced in an amount of from 1 to 2% by weight, preferably 6% by weight, relative to the amount of hygroscopic salt. If not pure hygroscopic salts are used, such as, for example, calcium chloride, magnesium chloride or a mixture of these salts, but their mixture with inert substances, among which may be ground

Смачн Ю1ЭДЯ агент добавл ют или от дельно примеривают его к впрыскиваемой воде.The lube agent is added or separately tried on to the injected water.
Дл устранени непри тного- запаха в смесь дополнительно ввод т душистые вещества в количестве от 0,1 до 0,2 вес. % по отношению к общему весу готового продукта.To eliminate the unpleasant smell, fragrant substances are additionally introduced into the mixture in an amount of from 0.1 to 0.2 weight. % relative to the total weight of the finished product.
Добавка тонко распыленного продукта вызывает рекр стаплиза1гаю и агломерацию отдельных частичйк тюртчлш соли между собой.The addition of a finely sprayed product causes reclamation and agglomeration of the individual particles of turtchlsh salt among themselves.
в результате этого происходит св зывание наиболее мелких частичек и предотвращение их уноса .рудничным воздутсомas a result of this, the smallest particles are bound and their entrainment is prevented.
