Description
лируют регул тором уровн 8 с клапаном 9.Level regulator 8 with valve 9.
При установившемс режнме автоматического регулировани в нижней части ректификационной колонны 1 кипение в подогревателе 2 протекает с определенной посто нной скоростью парообразовани , что обеспечивает посто иство плотности нарожидкостной смеси в процессе кипени , в св зи с чем перепад давленнй между нижним и верхним сло ми кип щей смеси не измен етс - скорость изменени равна О, сигнал коррекции отсутствует .At steady state of automatic regulation in the lower part of the distillation column 1, boiling in the preheater 2 proceeds at a certain constant rate of vaporization, which ensures a constant density of the antifluid mixture during boiling, due to which the pressure difference between the lower and upper layers of the boiling mixture unchanged — the rate of change is O, the correction signal is absent.
При наличии возмущени по температуре регул тор 4 измен ет полол ение клапана 3, измен подачу теплоносител в подогреватель 2, скорость парообразовани измен етс , что определ ет наличие скорости изменени иерепада давлени , измер емого датчиком 6. Преобразователь 7 сигналом управлени корректирует регул тор 4 со знаком, противоположным действию возмущени от датчика температуры 5.If there is a disturbance in temperature, regulator 4 changes the polarization of valve 3 by changing the flow of coolant to heater 2, the rate of vaporization changes, which determines the rate of change and pressure differential measured by sensor 6. The converter 7 adjusts regulator 4 with control signal the opposite of the disturbance from the temperature sensor 5.
В результате действи коррекции клаиан 3 уменьшает скорость изменени своего иоложени , нредотвраида резкое возмущение процесса . Сигнал коррекции возникает во всех случа х изменени темиературы, давлени и состава сырь и его воздействие направлено на предотвращение резкого возмущени ироцесса регулировани .As a result of the correction, Klaian 3 reduces the rate of change of his or her position, while the predotvraid is a sharp disturbance of the process. The correction signal occurs in all cases of change in temperature, pressure, and composition of the raw material and its effect is aimed at preventing a sharp disturbance of the control process.
Использование изобретени обеспечивает более устойчивое регулирование теплового режима процесса ректификации, что способствует более четкому разделепию многокомпонентных смесей и улучшению качества продукцин .The use of the invention provides a more stable regulation of the thermal regime of the rectification process, which contributes to a clearer separation of multicomponent mixtures and an improvement in the quality of products.
