Description

Изучение режима работы сланцеперегонных шахтных печей показало, что греющие газы движутс  преимущественно по периферии печи, где и протекает интенсивно пчрогенный процесс.The study of the operating mode of slate-shale shaft furnaces showed that the heating gases move mainly along the periphery of the furnace, where the intensively apogenic process takes place.

В центральной же части печи, в виду замедленного течени  теплоносител , сланец прогреваетс  гораздо медленнее.In the central part of the kiln, in view of the slow flow of the heat transfer fluid, the slate is heated much more slowly.

Между тем известно, что если кусок сланца нагреваетс  медленно и долгое врем  пребывает при температуре 350-400°, то он превращаетс  в асфальт, разм гчаетс  и образует с соседними кусками слипщуюс  массу. Выделение сланцевого масла из этой массы в зоне перегонки происходит неэффективно, а наличие значительного количества масла в массе, переход щей в зону горени , обусловливает развитие излишне высоких температур и интенсивное шлакообразование.Meanwhile, it is known that if a piece of shale is heated slowly and for a long time stays at a temperature of 350-400 ° C, it turns into asphalt, softens and forms a cohesive mass with adjacent pieces. The extraction of shale oil from this mass in the distillation zone is inefficient, and the presence of a significant amount of oil in the mass passing into the combustion zone causes the development of excessively high temperatures and intensive slag formation.

В предлагаемой шахтной печи эти недостатки устранены тем, что в зоне перегонки сланца, в осевой части генератора, вмонтирован сердечник. В результате этого из рабочего пространства печи исключаетс  осева  часть зоны перегонки, где начинает24In the proposed shaft furnace, these disadvantages are eliminated by the fact that in the distillation zone of the slate, in the axial part of the generator, the core is mounted. As a result, the axial part of the distillation zone is excluded from the working space of the furnace, where it starts 24

с  асфальтообразование и создаетс  правильное направление движени  сланца по периферии навстречу потоку греющих газов.the asphalt formation also creates the correct direction of movement of the shale along the periphery towards the flow of heating gases.

Предлагаема  печь схематически изображена на чертеже. Форма.печи с суженной верхней и расширенной нижней частью обусловливает скорости продвижени  реагентов в соответствии с технологическими требовани ми процесса. Подвешенный в зоне перегонки сланца сердечник / предотвращает образование сплошных асфальтовых масс в осевой части печи.The proposed furnace is shown schematically in the drawing. The form of the furnace with a narrowed upper and extended lower part determines the rates of advancement of the reagents in accordance with the technological requirements of the process. The core suspended in the shale distillation zone / prevents the formation of solid asphalt masses in the axial part of the kiln.

В верхней части печи имеетс  загрузочна  камера 2 с куполом 3 и подвижным конусом 4. Несколько ниже вмонтирован вышеуказанный металлический сердечник 1, нижн   часть которого выполнена из жароупорного материала. Во врем  работы печи пары сланцевого масла отсасываютс  вместе с теплоносителем через трубу 5. Остаток сланца переходит через конический по с в расширенную часть печи и, постепенно опуска сь, сгорает в потоке дуть , создава  теплоноситель. Зола удал етс  при помощи вращающейс  решетки 6.In the upper part of the furnace there is a loading chamber 2 with a dome 3 and a movable cone 4. Above, the above-mentioned metal core 1 is mounted, the lower part of which is made of heat-resistant material. During furnace operation, shale oil vapors are sucked together with coolant through pipe 5. The remainder of the shale passes through the conical section into the expanded part of the furnace and, gradually lowering, burns in the stream to blow, creating a coolant. The ash is removed by means of a rotating grate 6.
