Изобретение относитс к аппаратам дл псевдоожижени дисперсных материалов и может быть использовано при сушке, прокалке, термообработке материалов в химической, пищевой и других отрасл х промышленности, а также при проведении тетеротеиных химических реакций с псевдоожиженным слоем катализатора.The invention relates to apparatus for fluidizing dispersed materials and can be used for drying, calcining, heat treating materials in the chemical, food and other industries, as well as for conducting tetrotheic chemical reactions with a fluidized bed of catalyst.
Известно устройство дл псевдоожижени твердых частиц, содержащее перфорированную горизонтальную пластину, закрепленные в пластике сопла и отбойную наклонную перегородку, расположенную под сопламир. ,A device for fluidizing solid particles is known, comprising a perforated horizontal plate, fixed in the plastic of the nozzle, and an inclined baffle located under the nozzle. ,
Известен также реактор с псевдоожиженным слоем, содер«аи(ий вертикальный корпус с днищем, газораспределительное устройство, расположенное в верхней части корпуса, сопла, сое- j диИенные с газораспределительным устройством и направленные в сторону днища, и штуцеры ввода и вывода газа t2.Also known is a fluidized bed reactor, containing ai (its vertical casing with a bottom, a gas distribution device located in the upper part of the casing, nozzles, ji-directional with the gas distribution device and directed toward the bottom, and gas inlets and outlets of gas t2.
Недостатками известных аппаратов вл етс то, что существуют застойные зоны между соплами, в которых отсутствует перемешивание дисперсного материала, не обеспечиваетс интенсивное перемешивание фаз, определ ющее эффективность процессов, проводимых в слое дисперсного материала , возможно забивание отверстий и перфорированной решетки дисперсным материалом.The disadvantages of the known apparatus are that there are stagnant zones between the nozzles, in which there is no mixing of the dispersed material, there is no intensive mixing of the phases, which determines the efficiency of the processes carried out in the layer of dispersed material, it is possible that the holes and perforated grid are blocked by the dispersed material.
Цель изобретени - интенсификаци процессов путем вихревого перемешивани частиц твердого материала параллельными потоками газа.The purpose of the invention is the intensification of processes by vortex mixing of particles of solid material by parallel gas flows.
Эта цель достигаетс тем, что в устройстве на внутренней поверхности днища соосно под соплами выполнены сферические углублени .This goal is achieved by spherical recesses made coaxially under the nozzles in the device on the inner surface of the bottom.
На чертеже изображен реактор, продольный разрез.The drawing shows the reactor, a longitudinal section.
