Description
Предметом изобретени вл етс способ сушки картона и других тонких рулонных материалов в сушильной части соответствуюш.их машин , оснаш:енных сушильными цилиндрами.The subject of the invention is a method of drying cardboard and other thin roll materials in the drying part of the respective machines equipped with drying cylinders.
Известные дл этих целей способы сушки не обеснечивают необходимого ускоренного процесса сушки картона и других тонких рулонных материалов.The methods of drying known for these purposes do not provide for the necessary accelerated process of drying cardboard and other thin rolled materials.
В описываемом способе этот недостаток до некоторой степени устранен тем, что процесс сушки в начале ведут при температуре греющей поверхности первых цилиндров в 300-350°, затем температуру постепенно снижают, до 125-130° в конце сушки; при этом постепенное понижение температуры от первого сушильного цилиндра к последнему осуществл ют использу в качестве сушильного агента пары дифенильнои смеси в начале сушки и вод ные пары в конце сушки.In the described method, this disadvantage is to some extent eliminated by the fact that the drying process at the beginning is carried out at a temperature of the heating surface of the first cylinders of 300-350 °, then the temperature is gradually reduced to 125-130 ° at the end of the drying; wherein the gradual decrease in temperature from the first drying cylinder to the last is carried out using, as the drying agent, diphenyl mixture pairs at the beginning of drying and water vapor at the end of drying.
Предмет изобретени Subject invention
Способ сушки картона и других тонких рулонных материалов в сушильной части соответствующих машин, оснащенных сушильными цилиндрами, отличающийс тем, что, с целью ускорени сушки без потери качества высушиваемого материала, процесс сушки начинают при температуре греющей поверхности первых цилиндров в 300-350°, затем при помощи дросселировани поступлени теплоносител и замены во второй группе цилиндров паров дифенильной смеси водными парами температуру греющей поверхности постепенно снижают до 125-130°.The method of drying cardboard and other thin roll materials in the drying part of the respective machines equipped with drying cylinders, characterized in that, in order to accelerate drying without losing the quality of the material being dried, the drying process starts at the heating surface temperature of the first cylinders 300-350 °, then the help of throttling the coolant intake and replacement of the diphenyl mixture with water vapor in the second group of cylinders with the temperature of the heating surface is gradually reduced to 125-130 °.
