(54) СПОСОБ УПРАВЛЕНИЯ ПРОЦЕССОМ СУШКИ(54) METHOD FOR MANAGING THE DRYING PROCESS
II
Изобретение относитс к сушильной технике , а именно к автоматизации процесса сушки.The invention relates to a drying technique, in particular to the automation of the drying process.
Известны способы управлени процессом сушки путем измерени влагосодержани сушильного агента с последуюшим воздействием на расход рециркул та, а также измерени расхода и температуры теплоносител перед сушкой и воздействи на подачу холодного воздуха и теплоносител 1.Methods are known for controlling the drying process by measuring the moisture content of the drying agent with a subsequent effect on the recycle flow rate, as well as measuring the flow rate and temperature of the coolant before drying and affecting the flow of cold air and coolant 1.
Однако известный способ не позвол ет достигнуть требуемого качества управлени .However, the known method does not allow to achieve the required quality control.
Целью изобретени вл етс повышение качества управлени .The aim of the invention is to improve the quality of control.
Цель достигаетс тем, что дополнительно измер ют температуру теплоносител после сушки и по ней корректируют расход рециркул та, а на подачу холодного воздуха воздействуют по расходу теплоносител , а на подачу последнего - по температуре перед сушкой.The goal is achieved by additionally measuring the temperature of the heat-transfer medium after drying, and recirculating the flow rate is adjusted according to it, and the flow of cold air is influenced by the flow rate of the heat-transfer fluid, and the flow rate of the latter is measured by the temperature before drying.
На чертеже представлена блок-схема устройства дл реализации данного способа.The drawing shows a block diagram of a device for implementing this method.
Устройство содержит вентил тор 1, объем 2 сушки, датчик 3 температуры, регул тор 4 температурь, задатчик 5, исполнительный механизм 6, измеритель расхода 7,The device contains fan 1, volume 2 drying, temperature sensor 3, temperature controller 4, unit 5, actuator 6, flow meter 7,
регул тор 8, задатчик 9, исполнительный механизм 10, измеритель влагосодержани И, регул тор 12 с задатчиком 13, сумматор 14, измеритель 15 температуры теплоносител после сушки, регул тор 16 с задатчиком 17, исполнительный механизм 18, регулирующие органы 19, 20 и 21.the controller 8, the setting device 9, the actuator 10, the moisture content meter And, the controller 12 with the setting device 13, the adder 14, the meter 15 of the heat carrier temperature after drying, the controller 16 with the setting device 17, the actuator 18, the regulators 19, 20 and 21 .
Устройство работает- следующим образом .The device works as follows.
Гор чий и холодный теплоносители поHot and cold heat transfer media
IQ отдельным трубопроводам поступают через вентил тор 1 на вход сушильного объема 2. Посто нство температуры теплоносител на входе сушильного объема поддерживаетс с помошью датчика 3 температуры, автоматического регул тора 4 температуры сIQ to individual pipelines come through the fan 1 to the inlet of the drying volume 2. The temperature of the heat carrier at the inlet of the drying volume is maintained with the help of the temperature sensor 3, the automatic temperature regulator 4 with
