Description
Предлагаемое изобретение имеет целью приготовление кирпичей, выдерживающих без разрушени продолжительное действие расплавленного сернистого натри при высокой температуре.The present invention aims at preparing bricks that can withstand without destruction the long-term effect of molten sodium sulphide at high temperature.
Недостаток существующих заводских печей, служащих дл изготовлени сернистого натри , заключаетс , по л нению автора, в том, что под Bv и ниev расплавленной сернистой щелочи быстро разъедаетс под этих печей. Дл устранени этого недостатка изобретатель предлагает вз ть в качестве материала дл кирпичей вещество, совершенно не реагирующее химически с сернистым натрием, не плав щеес при температуре заводских печей и достаточно прочное в механическом смысле. Таким веществом автор считает сернистый кальций , легко получаемый восстановлением гипса углем в краснокалильном жару. Дл придани кирпичам механической св зности и прочности, изобретатель рекомендует при их изготовлении прибавл ть к смеси гипса с углем известное количество огнеупорной глины, смесь формировать в кирпичи и обжигать их обычным способом в сильном жару.A disadvantage of the existing factory furnaces used to make sodium sulphide is, according to the author, that under Bv and the molten sulphurous alkali, it is quickly eaten away under these furnaces. To eliminate this drawback, the inventor proposes taking as a material for bricks a substance that does not chemically react with sodium sulphide, does not melt at factory furnace temperatures, and is rather strong in a mechanical sense. The author considers calcium sulfide such a substance, which is easily obtained by the reduction of gypsum with coal in the red-hot heat. In order to impart mechanical coherence and strength to bricks, the inventor recommends adding a known amount of refractory clay to the mixture of gypsum and coal, making the mixture into bricks and firing them in the usual way.

ПРЕДМЕТ ИЗОБРЕТЕНИЯ.SUBJECT OF INVENTION.
Способ приготовлени кирпичей дл футеровки печей, служащих дл получени сернистого натри из сернонатриевой соли, отличающийс тем, что массу из гипса, угл и огнеупорной глины формуют и затем прокаливают в обычных кирпиче - обжигательных печах.A method of preparing bricks for lining furnaces used to obtain sodium sulfide from a sodium sulfonate salt, characterized in that the mass of gypsum, coal and refractory clay is molded and then calcined in conventional brick kilns.
