Description
Известные способы сушки материалов в кип щем слое неприменимы дл сушки суспензий и растворов, так как барботаж сушильного агента через сушильный материал приводит к комкованию последнего при значительной его влажности.The known methods of drying materials in a fluidized bed are not applicable for drying suspensions and solutions, since the sparging of the drying agent through the drying material leads to the clumping of the latter with its considerable humidity.
Особенность предлагаемого способа сушки заключаетс в том, что суспензию или раствор в жидком виде подают в кип ш.ий слой инертного зернистого материала, а отделение высушенного материала от парогазовой смеси, вынесенной из шахты, осуш,ествл ют вне зоны сушки тем или иным способом (в циклонах, фильтрах и т. п. устройствах).The peculiarity of the proposed method of drying is that the suspension or solution in liquid form is fed into the boiling layer of inert granular material, and the separation of the dried material from the vapor-gas mixture removed from the mine is dried outside the drying zone one way or another ( in cyclones, filters, etc. devices).
Указанный способ обеспечивает интенсификацию процесса сушки суспензий и растворов.This method provides an intensification of the process of drying suspensions and solutions.
Дл выполнени предлагаемого способа сушки предусмотрено устройство , содержаш,ее вертикальную шахту с беспровальноц. решеткой, загрузочный бункер дл сырого материала с питателем, циклон и приемник сухого материала.In order to carry out the proposed method of drying, a device is provided which contains its vertical shaft with an unscheduled one. grate; raw material feed hopper; cyclone; and dry material receiver.
На чертеже изображена схема в обш,ем виде предлагаемого устройства дл сушки суспензий и растворов в кип щем слое инертного материала.The drawing shows a diagram in a general form of the proposed device for drying suspensions and solutions in a fluidized bed of inert material.
В шахту / с беспровальной решеткой 2 насыпаетс слой инертного зернистого материала 3, через который продуваетс сушильный агент (нагретый воздух, дымовые газы). В кип щий слой зернистого материала 3 через питатель 4 из бункера 5 подаетс суспензи или раствор сушимого продукта, распредел ющиес по поверхности зернистого материала тонким слоем. Высушенные частицы материала отдел ютс от поверхности зерен и вместе с сушильным агентом унос тс в циклон 6, где осуществл етс отделение от парогазовой, смеси высушенного материала, удал емого в приемник 7.A layer of inert granular material 3 is poured into the shaft / s besprovalny grating 2, through which the drying agent (heated air, flue gases) is blown. In the fluidized bed of granular material 3, a slurry or solution of the dried product is distributed through the feeder 4 from the hopper 5 and distributed over the surface of the granular material in a thin layer. The dried material particles are separated from the surface of the grains and, together with the drying agent, are carried away to cyclone 6, where they are separated from the vapor-gas mixture of the dried material that is removed to the receiver 7.
Подвод тепла, необходимого дл сушки, осуществл ют различными способами: подогревом в калориферах, дымовыми газами или подогревом через поверхность теплообмена 8 в слое зернистого материала 9.The heat required for drying is supplied in various ways: by heating in calorifiers, by flue gases or by heating through the heat exchange surface 8 in the layer of granular material 9.
