Description

Предлагаема  печь предназначена дл  обжига дробленого известн ка и других сыпучих материалов во взвешенном состо нии (на лету), при вдувании материала снизу, попутно с гор щим газом. Обожженный материал задерживаетс  циклоном , а отход щие газы используютс  дл  предварительного подсушивани  и подогрева материала.The proposed furnace is intended for roasting crushed limestone and other bulk materials in suspension (on the fly), while blowing material from the bottom, along with a burning gas. The calcined material is retained by the cyclone, and the exhaust gases are used to pre-dry and preheat the material.

Изображенна  на чертеже в схематическом виде печь дл  обжига дробленого известн ка и других сыпучих материалов во взвешенном состо нии состоит из проходной стволообразной шахты //, снабженной в нижней части вихревой горелкой, расположенной под питающим шнехом Ю. Циклон 13 служит дл  отделени  порош ообразного продукта от газовой смеси, направл емой по трубопроводу /5 в рекуперативный воздухонагреватель 16, а оттуда через служащую дл  подсушивани  сырого материала трубу 5, сепаратор 6 и расходный циклон 9-в эксгаустор 22. Сырой материал через грохот /, бункер 2 и дробилку 3 поступает дл  подсушивани  в трубу 5 и далее в расходный циклон 9. Затем порошкообразный материал подаетс  в стволообразную шахту 11 при помощи шнека 10 и вихревой горелки. Влетающие через горелку подогретый воздух и горючие газы,The baking kiln shown in the drawing for firing crushed limestone and other bulk materials in a suspended state consists of a through stem shaft, equipped with a vortex burner in the lower part located under the feed screw Y. Cyclone 13 serves to separate the powder product from the gas mixture directed through the pipeline / 5 to the recuperative air heater 16, and from there through the pipe 5 used for drying the raw material, the separator 6 and the expendable cyclone 9-to the exhauster 22. The raw material the screen cutter, the bunker 2 and the crusher 3 are fed for drying into the pipe 5 and further into the expendable cyclone 9. Then the powdered material is fed into the stem shaft 11 by means of the screw 10 and a vortex burner. Preheated air and combustible gases rushing through the burner,

Дл  отделени  готовой продукции от газовой смеси служит циклон 13, снабженный спускной трубой 14. Топливо поступает из бункера 19 через автоматические весы 20 и транспортер 21 в полугенераторную топку 18.By acquiring a large circumferential speed at the inlet, the wellhead of the barrel is prevented from blocking and crushed material poured into the furnace is carried through the entire height of the baking trunk sufficient to complete the process of dissociation or calcination of the material. To separate the finished product from the gas mixture, a cyclone 13 is provided, equipped with a drain pipe 14. The fuel comes from the hopper 19 through the automatic balance 20 and the conveyor 21 to the semi-generating furnace 18.
