Изобретение относитс к устройствам дл сушки сыпучих материалов и может найти применение дл сушки зерна на хлебоприемных предпри ти х и в сельском хоз йстве.The invention relates to devices for drying bulk materials and can be used for drying grain at grain-receiving enterprises and in agriculture.

Известны -установки дл сушки сыпучих материалов, содержащие сушильную камеру кип щего сло и подключенный к ней снизу газораспределитель ный короб с псевдоожиженным слоем инертной насадки 1J .Known are installations for drying bulk materials that contain a fluidized bed drying chamber and a gas distribution box with a fluidized bed of an inert packing 1J connected to it below.

.Недостатком известной установки вл етс невысокий тепловой КПД. A disadvantage of the known installation is the low thermal efficiency.

Целью изобретени вл етс повышение теплового КПД.The aim of the invention is to increase thermal efficiency.

С этой целью установка содержит дополнительную камеру с псевдоожиженным слоем инертной насадки, имеющую с сушильной камерой обшие стенку и газораспределительную решетку, часть которой подключена к коробу, а остальна - к патрубку дл подачи атмосферного воздуха, причем дополнительна камера имеет два выходных патрубка , один из которых подключен к коробу .For this purpose, the installation contains an additional fluidized bed chamber with an inert nozzle, which has a common wall and a gas distribution grid with a drying chamber, part of which is connected to the duct and the rest to the nozzle for supplying atmospheric air, and the additional chamber has two outlet nozzles, one of which connected to the box.

На чертеже изображена схема установки .The drawing shows the installation diagram.

Установка содержит- сушильную камеру 1, газораспределительный короб 2, с инертной насадкой, снабженный патрубками 3 и 4 дл подачи агента сушки и подогретого воздуха, дополнительную камеру 5 с инертной насадкой, имеющую с сушильной камерой общие стенку 6 и газораспределительную решетку 7 и снабженную патрубком 8 дл подачи охлаждающего воздуха, и патрубками 9 и 10 дл выхода подогретого воздуха , загрузочное 11 и разгрузочное 12 устройства и диффузор 13 дл отработавшего агента сушки.The installation comprises: a drying chamber 1, a gas distribution duct 2, with an inert nozzle, equipped with nozzles 3 and 4 for supplying a drying agent and heated air, an additional chamber 5 with an inert nozzle, having a common wall 6 with the drying chamber and a gas distribution grid 7 and equipped with a nozzle 8 for the supply of cooling air, and the connections 9 and 10 for the exit of the heated air, the charging 11 and the discharge 12 devices and the diffuser 13 for the spent drying agent.

Установка работает следующим образом .The installation works as follows.

Влажный материал через загрузочное устройство 11 непрерывно подают в сушильную камеру. Высокотемпературный агент сушки по патрубку 3. подают в газораспределительный короб 2, заполненный промежуточным твердь1м дисперсным теплоносителем.Wet material through the loading device 11 is continuously fed into the drying chamber. The high-temperature drying agent through the pipe 3. is fed to the gas distribution duct 2 filled with an intermediate solid 1m dispersed coolant.

Claims

In the gas distribution duct, due to intensive mixing of the solid phase, heat is transferred from the gaseous agent to the heated air supplied through pipe 4 and the heating of the heat exchanger is heated, and the gaseous drying agent having a sufficiently high temperature enters the chamber 5 filled with an intermediate solid heat carrier , separated by a wall 6 from the chamber 1 and having with it a common gas distribution grid 7,. From chamber 5, a large part of the spent agent is emitted into the atmosphere through nozzle 10, and the rest, together with the heated outside air entering the chamber, an additional trap 8, through nozzle 9 connected to nozzle 4, is fed into the gas distribution box, where it is mixed with part of the initial agent, is heated in the fluidized bed of the inert nozzle and through the gas distribution grid 7 enters the drying chamber. In the chamber 1, the drying agent heats and dries the material, which is continuously released from the chamber with the help of a discharge device 12. The drying agent that has spent in the chamber 1 through the diffuser 13 is emitted into the atmosphere. Due to the multistage heating of the air in the layer with the inert nozzle 6, a better utilization of heat is achieved, which leads to an increase in thermal efficiency. Claims An apparatus for drying bulk materials, preferably grains, contains a drying chamber of a boiling layer and a gas distribution box with a fluidized bed of an inert nozzle connected to it, which, in order to increase thermal efficiency, contains an additional chamber with an inert fluidized bed the nozzle, which has a common wall with the drying chamber and a gas distribution grid, a part of which is connected to the duct and the rest to the nozzle for the supply of atmospheric air, The supplementary chamber has two output connections, one of which is connected to the box.
