Description
При известных способах обжига мелкозернистых материалов, например флотационного концентрата, в псевдоожиженном кип щем слое не обеспечиваетс вы;сока удельна производительность печей.With known methods for firing fine-grained materials, such as flotation concentrate, you are not provided in a fluidized bed; you have the specific productivity of the furnaces.
Дл устранени этого недостатка предлагаетс вводить в исходные материалы перед обжигом не более 0,5% весовых хлоридов щелочных или щелочноземельных металлов или сульфатов щелочных металлов в виде порошков или концентрированных растворов. В качестве таких реагентов можно применить хлористый натрий, сульфат натри и пр. Эти реагенты можно добавл ть в виде концентрированного раствора, подаваемого через тонкораспыливающие форсунки на TpaHicnopTepnyro ленту, перемещающую подлежащий обжигу материал к печи. Можно также примен ть сухие тонкомолотые реагенты, равномерно перемешиваемые с поступающим в печь сырьем. Получаемый из такого сырь огарок мало отличаетс по гранулометрическому составу от огарков составной щихты, что дает возможность повЫ|Сить удельные нагрузки печей дл обжига сульфидов в кип щем слоеПредмет изобретени To eliminate this drawback, it is proposed to introduce into the raw materials before calcining no more than 0.5% by weight of alkali or alkaline earth metal chlorides or alkali metal sulphates in the form of powders or concentrated solutions. Sodium chloride, sodium sulfate, etc. can be used as such reagents. These reagents can be added in the form of a concentrated solution supplied through microfluidising nozzles to a TpaHicnopTepnyro tape, transferring the material to be calcined to the furnace. It is also possible to use dry, finely ground reagents that are uniformly mixed with the raw material entering the furnace. The cinder obtained from such raw material differs little in its granulometric composition from that of composite solvents, which makes it possible to increase the specific loads of furnaces for calcining sulphides in a fluidized bed.
Способ обжига мелкозернистых материалов, например флотационного концентрата, в псевдоожижениом (кип щем) слое, отличающийс тем, что, с целью повышени удельной производительности печи , перед обжигом в исходные материалы ввод т не более 0,5% весовых хлоридов щелочных или щелочноземельных металлов или сульфатов щелочных металлов в виде порошков или концентрированных растворов.The method of firing fine-grained materials, such as flotation concentrate, in a fluidized bed (fluidized bed), characterized in that, in order to increase the specific productivity of the furnace, before firing, no more than 0.5% by weight of alkali or alkaline earth metals or sulphates are added to the starting materials alkali metals in the form of powders or concentrated solutions.
