Description
Изобретение относитс к энергетике , в частности к автоматизации процесса сушки материалов.The invention relates to energy, in particular to the automation of the process of drying materials.
Известны способы автоматического управлени процессом сушки материалов путем воздействи на расход сушильного агента по разности температур агента и материала j l Однако известный способ автоматического управлени процессом сушки не обеспечивает требуемого качества сушки.Methods are known for automatically controlling the drying process of materials by influencing the flow rate of the drying agent according to the temperature difference between the agent and the material. However, the known method for automatically controlling the drying process does not provide the required quality of drying.
Цель изобретени - повышение качества суижи путем стабилизации процесса .The purpose of the invention is to improve the quality of the fit by stabilizing the process.
Поставленную цель достигают тем, что измерение температуры агента и материала производ т в одной и той же зоне сушки, а на расход агента воздействуют в этой же зоне и тем, что разность температур поддерживают в пределах 2-5 С.This goal is achieved by the fact that the temperature measurement of the agent and the material is made in the same drying zone, and the flow rate of the agent is affected in the same zone and by the fact that the temperature difference is maintained within 2-5 C.
На чертеже представлена система управлени -сушкой, реализующа данный способ управлени .The drawing shows a control system that implements this control method.
Система содержит датчик 1 температуры материала, датчик 2 температуры сушильного агента, задатчик 3, регул тор 4, элемент сравнени 5, датчики 1 и 2 установлены в сушилкеThe system contains material temperature sensor 1, drying agent temperature sensor 2, unit 3, controller 4, reference element 5, sensors 1 and 2 are installed in the dryer
6, а регул тор 4 св зан с регулирующим органом 7.6, and controller 4 is associated with the regulatory authority 7.
Система работает следующим образом .The system works as follows.
Датчики 1 и 2 измер ют температуру агента и материала, разность их показаний сравнивают на элементе сравнени 5 с сигналом задатчика и воздействуют на расход агента по Sensors 1 and 2 measure the temperature of the agent and the material, the difference in their readings is compared on the element of comparison 5 with the setpoint signal and affects the flow rate of the agent over
10 отклонению разности от задани с помощью регул тора 4 и регулирующего органа 7.10 deviation of the difference from the task by means of the controller 4 and the regulator 7.
Таким образом, при воздействии на расход агента по разности темпе15 ратур между материалом и агентом повышаетс точность регулировани влажности материала и следовательно качество сушки.Thus, by affecting the flow rate of the agent by the temperature difference between the material and the agent, the accuracy of controlling the moisture of the material and, consequently, the quality of drying is improved.
