Description
(54) СПОСОБ АВТОМАТИЧЕСКОГО УПРАВЛЕНИЯ ПРОЦЕССОМ РАСПЫЛИТЕЛЬНОЙ СУШКИ(54) METHOD FOR AUTOMATIC CONTROL OF THE SPRAY DRYING PROCESS
Изобретение относитс к автоматическому управлению процессом распылительной сушки, например, с мокрой очисткой отработанного теплоносител , и может найти применение в микробио-: логической, химической, медицинской и пищевой промышленности.The invention relates to the automatic control of the spray drying process, for example, with the wet scrubbing of the spent heat carrier, and may find application in the microbiological, chemical, medical and food industries.
По основному авт. св. N° известен способ автоматического управлени процессом распылительной сушки путем воздействи на расход греющей среды по температуре теплоносител с подачей корректирующего сигнала по расходу подаваемого на сушку материала, а также измерени расхода выпаренной воды в процессе мокрой очистки и концентрации сухих веществ в подаваемом на сушку материале , причем по расходу воды и величине концентрации сухих веществ воздействуют на корректирующий сигнал по расходу материала 1 .According to the main author. St. N °, a method for automatically controlling the spray drying process is known by affecting the heating medium flow rate according to the temperature of the heat transfer medium by applying a correction signal on the flow rate of the material supplied to the drying, as well as measuring the flow rate of evaporated water during the wet cleaning process and the concentration of dry substances in the material supplied to the drying, the flow of water and the concentration of dry substances affect the correction signal for the flow of material 1.
Недостатком этого способа вл етс низкое качество управлени ввиду того, что не учитываетс влага, содержаща с во вход щем в сушилку теплоносителе, а также влага, содержаща с в отработанном теплоносителе на выходе из мокрой очистки, что не позвол ет с достаточной точностью при различных атмосферных услови х свести материальный баланс процесса сушки.The disadvantage of this method is poor control quality due to the fact that the moisture contained in the coolant entering the dryer is not taken into account, as well as the moisture contained in the waste coolant at the outlet of the wet scrubber, which does not allow for sufficient accuracy at different atmospheric levels. conditions reduce the material balance of the drying process.
Цель изобретени - повышение точ10 ности регулировани .The purpose of the invention is to improve the accuracy of regulation.
Поставленна цель достигаетс тем, что измер ют влажность теплоносител перед сушкой и после мокрой очистки и по полученным сигналам дополнитель15 но корректируют; расход греющей среды.This goal is achieved by measuring the humidity of the coolant before drying and after wet cleaning, and, according to the received signals, is additionally corrected; heating medium consumption.
