Description
Известные способы кристаллизации сульфата закиси железа из отвальных растворов, получаемых ипи травлении изделии из чериых металлов, св заны с большими трудност ми и ведут к потере серной 1 цслоты, содержащейс в этих растворах.The known methods of crystallization of ferrous sulfate from waste solutions obtained by etching a black metal product are very difficult and lead to the loss of sulfuric acid containing in these solutions.
Отличительна особенность описываемого способа регенерации тракцлььых растворов дл травлени изделий из черных металлов состшгг в том, что удаление железа из раствора осуществл ют посредством его окислени кислородом под давлением ири повыщениой температуре. Такой способ позвол ет возвращать травильные растворы в производство и удал ть из них железо в виде товарного иродукта.A distinctive feature of the described method of regeneration of traction solutions for pickling ferrous metal products is that the removal of iron from the solution is carried out by oxidizing it with oxygen under pressure and increasing temperature. This method allows the pickling solutions to be returned to production and iron is removed from them as a commercial product.
Дл отделени регенерированного раствора от выпавшего осадка нроцесс окислени травильного раствора кислородом ведут при 140-160 иод давлением 5-8 кг/c.ir. При этом ироиесс идет с образованием безводной окиси железа, котора выпадает в виде тонкодисиерсного т желого фиолетово-красного осадка, используемого, например , в качестве абразивного материала (крокус) или пигмента длиTo separate the regenerated solution from the precipitated precipitate, the process of oxidizing the pickling solution with oxygen is carried out at 140-160 iodized with a pressure of 5-8 kg / c. At the same time, iroiesc goes with the formation of anhydrous iron oxide, which precipitates as a fine violet-red sediment used, for example, as an abrasive material (crocus) or as a pigment
красок.paints.
Непрерывна регенераци травильных растворов может обеспечить замкнутый процесс, не требующиГ ирименени серной кислоты, расход которой в этом случае будет онредел т1)С только уровнем механических потерь.Continuous regeneration of pickling solutions can provide a closed process that is not required for sulfuric acid, the consumption of which in this case will be on the limit t1) With only the level of mechanical losses.
Предмет изобретени Subject invention
Сиособ регенерации травильных растворов дл травлени изделий из черных металлов, отличающийс тем, что, с целью удалени из раствора железа, их окисл ют кислородом при 140-160° ц давлении .5-8 кг/см.A regeneration method for etching solutions for pickling ferrous metal products, characterized in that, in order to remove iron from the solution, they are oxidized by oxygen at 140-160 ° C at a pressure of 5-8 kg / cm.
