(54) СПОСОБ СУШКИ МЕЛКОДИСПЕРСНЫХ МАТЕРИАЛОВ(54) METHOD FOR DRYING SMALL-DISPERSE MATERIALS
Изобретение относитс к технике сушки мелкодисперсных материалов и может быть использовано в химической, горнодобывающей фармацевтической, и других отрасл х промыш ленности. По основному авт. св. N 596794 известен способ сушки мелкодисперсных материалов путем непрерывного перемещени их сло через шлюзовые камеры и СВЧ-резонатор, в к тором увеличивают толщину сло высушиваемого материала путем уменьшени скорости его перемещени по фавнению со скоростью перемещени в шлюзовых камерах 1. Недостатком известного способа вл ютс низкие качество сушки и КПД СВЧ-генератор Пель изобретени - повышение качества сушки и увеличение КПД СВЧ-генератора. Поставленна пель достигаетс тем, что высушиваемый материал в СВЧ-резонаторе перемещают вдоль направлени распространени в ищи СВЧ-пол в точение времени, определ емо го по формуле 2 Мж ; т ;;:г с, -масса жидкой фазы, кг. -удельна скорость испарени при условии полного поглощени , кг/с-кВт,. N - мощность излучени СВЧ-генераторов , КВТ.. На чертеже схематически изображена установка , реализующа предлагаемый способ сушки. Установка содержит пр моугольный резонатор 1, соедине1тый с СВЧ-гбнератором 2 волновода 3, два ленточных конвейера 4 и 5, устройства дл загрузки 6 и выгрузки 7 дисперсного материала, приемный бункер 8 И камеру 9 дл воды. Установка работает следующим образом. Влажный мелкодисперсный материал через устройство дл загрузки 6 подаетс на первый , ленточный конвейер 5, с которого он пересыпаетс на второй ленточньпЧ конвейер 4, установленный в СВЧ-резонаторе I вдоль направлени распространени СВЧ-пол . Скорость конвейера 4 устанавливают ниже скорости подающего ленточного конвейера 5, благодар чемуThe invention relates to a technique for drying fine materials and can be used in chemical, mining, pharmaceutical, and other industries. According to the main author. St. N 596794 discloses a method of drying fine materials by continuously moving their layer through sluice chambers and a microwave resonator, and further increases the thickness of the layer of material being dried by reducing the speed of its movement along the speed at sluice chambers 1. drying and efficiency of the microwave generator Pel invention - improving the quality of drying and increase the efficiency of the microwave generator. The delivered pellet is achieved by the fact that the material to be dried in the microwave resonator is moved along the propagation direction to the microwave field in the search for a time determined by the formula 2 Mzh; t ;;: g with, is the mass of the liquid phase, kg. -specific evaporation rate under the condition of complete absorption, kg / s-kW ,. N is the radiation power of microwave generators, KWT. The drawing shows schematically an installation that implements the proposed drying method. The installation contains a rectangular resonator 1, connected to the microwave oven 2 of the waveguide 3, two belt conveyors 4 and 5, devices for loading 6 and discharging 7 dispersed material, receiving bin 8 and chamber 9 for water. The installation works as follows. The wet fine material is fed through the loading device 6 to the first belt conveyor 5, from which it is poured onto the second belt conveyor 4 installed in the microwave resonator I along the propagation direction of the microwave field. The speed of the conveyor 4 is set below the speed of the feeding belt conveyor 5, so that
