Изобретение относитс к технике сушки и может быть использовано в химической и других отрасл х промышленности.This invention relates to a drying technique and can be used in the chemical and other industries.
Известный способ сушки полидисперсных полимерных материалов состоит в нагреве их в кип щем слое.A known method of drying polydisperse polymeric materials consists in heating them in a fluidized bed.
Недостатками известного спосо&а вл ютс длительность процесса и неравномерност обработки материала, привод ща к образованию агломератов частиц и снижению качества продукта.The disadvantages of the known method are the duration of the process and uneven processing of the material, leading to the formation of agglomerates of particles and a decrease in the quality of the product.
Цель изобретени - интенсификаци процесса и повышение качества сушки.The purpose of the invention is to intensify the process and improve the quality of drying.
Это достигаетс тем, что нагрев осуш.есвл ют в два этапа, между которыми после достижени материалом влажности 10-15% производ т т родувку воздухом с температурой 2О-40 С, и на кип щий слой накладывают вибрационные колебани .This is achieved by the fact that the heating of the drying process is carried out in two stages, between which, after the material reaches 10-15% moisture, the blower is blown out with air at a temperature of 2 ° C to 40 ° C, and vibration vibrations are applied to the boiling bed.
Пример . Массу пресскомпозиции аминопласта с начальной влажностью 34% из смесител непрерывного действи подают на сушку при помощи ленточного транспортера . На первой стадии в виброки- п шем слое процесс ведут при температуре An example. The mass of the amino composition with an initial moisture content of 34% from a continuous mixer is fed to the dryer using a belt conveyor. In the first stage, in a vibratory layer, the process is carried out at a temperature
оabout
воздуха на входе 14О С, темепературе аминопласта на выходе 8О С, скорости воздуха 0,9-1,0 м/сек, амплитуде 2,О-2,5 мм, частоте 16 1/сек и экспозиции 2,5 мин до .влажности ами,нопласта 10%.air inlet 14О С, temperature of aminoplast at exit 8О С, air speed 0.9-1.0 m / s, amplitude 2, О-2.5 mm, frequency 16 1 / s and exposure 2.5 min. to humidity ami, noplast 10%.
Затем осуществл ют охламшенке амино- псласта в виброкип щем слое воздухом с температурой 20 С при скорости воздуха 0,6 м/сек, амплитуде 1,5-2 мм, частоте 16 1/сек и экспозиции 3 мин до температуры аминопласта 5О С.Then, an amino-plast is cooled in a vibro-boiling layer with air at a temperature of 20 ° C at an air speed of 0.6 m / s, an amplitude of 1.5-2 mm, a frequency of 16 1 / s and an exposure time of 3 minutes up to an aminoplast temperature of 5 ° C.
Далее на второй стадии сушки в виброкип щем слое процесс ведут при температуре воздуха на входе 95 С, амплитуде 1,О-1 ,5 мм, частоте 16 1/сек и экспозиции 3,5 мин до конечной влажности 2,0%.Next, in the second stage of drying in a vibrocall bed, the process is carried out at an inlet air temperature of 95 ° C, amplitude 1, O-1, 5 mm, frequency 16 1 / s and exposure time 3.5 minutes to a final moisture content of 2.0%.
Предлагаемый способ сушки позвол е сократить длительность сушки по сравнению с известным в 3,5-9 раз и значительно улучшить качество высушенной пресскомпозиции аминопласта.The proposed method of drying makes it possible to shorten the drying time compared to the known one by 3.5–9 times and significantly improve the quality of the dried amino position.
