Description

Известны газовые печи непрерывного действи  с наклонным или горизонтальным подом дл  обработки железной руды и других материалов , гор чих или холодных, во взвешенном состо нии в восстановительной или окислительной среде.;Continuous gas furnaces with an inclined or horizontal hearth are known for treating iron ore and other materials, hot or cold, in a suspended state in a reducing or oxidizing environment .;

Отличительна  особенность описываемой газовой печи состоит в том, что ее под состоит из р да желобов-приемников с установленными в них соплами дл  подвода под давлением гор чего или холодного газа или воздуха (в зависимости от примен емой обработки материалов) из общей воздушно-газовой коробки, примыкающей снизу к поду печи. В печах с наклонным подом сопла устанавливаютс  в желобах отвесно к поверхности пода, а в печи с горизонтальным подом- под углом в 75° в сторону выпускного отверсти  и в 105° -в сторону загрузочного отверсти . Этим обеспечиваетс  поступательное движение материалов во взвешенном состо нии от загрузочного отверсти  к выпускному.A distinctive feature of the described gas furnace is that it consists of a series of chute receivers with nozzles installed in them for supplying hot or cold gas or air under pressure (depending on the material treatment used) from a common air-gas box. adjacent to the bottom of the furnace. In inclined-hearth furnaces, the nozzles are installed in the grooves vertically to the surface of the hearth, and in an oven with a horizontal hearth, at an angle of 75 ° towards the outlet and 105 ° towards the inlet. This ensures the forward movement of materials in a suspended state from the loading opening to the outlet.

На чертеже схематически изображена описываема  печь.The drawing shows schematically the described furnace.

В бункер / подаетс  сыпучий материал, например, железна  руда, котора  попадает в рабочее пространство печи 2. Под действием силы т жести сыпучий материал скапливаетс  на поде 3 печи, поверхность которого выполнена в виде малых бункеров (желобов-приемников). Под печи перфорирован соплами 4.Bulk material is fed into the bunker, for example iron ore, which enters the working space of the furnace 2. Under the action of gravity, the bulk material accumulates on the hearth of the 3 furnaces, the surface of which is made in the form of small bunkers (chutes). Under the oven perforated nozzles 4.

Сжатый воздух или газ (в зависимости от характера процесса), поступающий через сопла в рабочую камеру печи из воздушно-газ.оврй коробки 5, примыкающей снизу к поду печи, поднимает материал и переносит его в следующий бункер. Так совершаетс  последовательное движение материала к выпускному отверстию в приемный бункер 6. При этом одновременно производитс  окисление или восстановление материала. В печах с наклонным подом сопла устанавливаютс   пёрггендикул рно поверхности пода, а при горизонтальном поде - под углом примерно 75° по направлению движени  материала.Compressed air or gas (depending on the nature of the process) coming through the nozzles into the working chamber of the furnace from the air-gas box 5, adjacent to the bottom of the furnace, lifts the material and transports it to the next bunker. In this way, a sequential movement of the material to the outlet opening in the receiving hopper 6 is performed. At the same time, the material is oxidized or reduced. In inclined-hearth furnaces, the nozzles are set to be phergegenic for the hearth, and for horizontal feeds, at an angle of about 75 ° in the direction of movement of the material.
