Description
(54) УСТРОЙСТВО ДЛЯ АВТОМАТИЧЕСКОГО РЕГУЛИРОВАНИЯ РЕЖИМА РЕКТИФИКАЦИОННОЙ КОЛОННЫ(54) DEVICE FOR AUTOMATIC REGULATION OF RECTIFICATION COLUMN MODE
вход которого соединен с датчиком давлени 8, а выход - с входом ограничител 10the input of which is connected to the pressure sensor 8, and the output - to the input of the limiter 10
Устройство работает следующим образом .The device works as follows.
При изменении количества сырь , подаваемого в колонну 3, с помощью 1 и 5, регул тора 4 и исполнительного механизма 6 измен етс поток орошени , что обеспечивает посто нную кратность орошени . При этом мен етс поток паров в колонне , вызыва изменение сигналов выхода датчиков 15 и ,8.When the amount of raw material supplied to column 3 changes, with the help of 1 and 5, controller 4 and actuator 6, the irrigation flow changes, which ensures a constant irrigation rate. This changes the flow of vapor in the column, causing a change in the output signals of the sensors 15 and, 8.
Таким образом в вычислитель 16 поступают измененные сигналы датчиков 8 и 15. Вычислитель 16 определ ет фактор эффективности разделени , сравнивает с заданным и определ ет величину давлени , которую нужно поддержать в колонке. Затем выходный сигнал с вычислител 16 поступает в ограничитель 10, где сравниваетс с максимально допустимым давлением , оттредел емым конструктивными особенност ми и вл ющимс дл данной ко- лоннь посто нным и минимально допустимым . Проверенный в ограничителе 1О, выходной сигнал поступает как задание регул тору 9. Выходной сигнал регул тора вызывает увеличение или уменьшение Thus, the transmitter 16 receives the altered signals from the sensors 8 and 15. The transmitter 16 determines the separation efficiency factor, compares with the preset and determines the pressure that needs to be maintained in the column. Then, the output signal from the calculator 16 enters the limiter 10, where it is compared with the maximum allowable pressure, which is determined by the design features and is constant and the minimum allowable for this column. Tested in limiter 1O, the output signal comes as a reference to the controller 9. The output signal from the controller causes an increase or decrease
крыти исполнительного механизма 11, что соответственно увеличивает или уменьшает поток жидкой фазы по линии 12 и приводит к восстановлению давлени в колонне .of the actuator 11, which accordingly increases or decreases the flow of the liquid phase through line 12 and leads to the restoration of pressure in the column.
