Description
Температуру в конце реактора 1 замер ют с помощью датчика 7 температуры и измер ют с помощью регул тора 12 через реле 9, сумматор 8 клапаном 16 на линии инициатора в реактор 1. Реле 9 передает сигнал с регул тора 12 на сумматор 8 только в момент снижени давлени в реакторе 1, т. е. при поступлении сигнала с выхода генератора 13.The temperature at the end of the reactor 1 is measured by the temperature sensor 7 and measured by the controller 12 via the relay 9, the adder 8 by the valve 16 on the initiator line to the reactor 1. The relay 9 transmits the signal from the controller 12 to the adder 8 only at the moment of decrease pressure in reactor 1, i.e. when a signal comes from the output of the generator 13.
В случае использовани в процессе полимеризации газообразного кислорода как инициатора , т. е. при транспортном запаздывании, генератор 13 периодических снижений давлени в реакторе 1 выдает сигнал на реле 9 после сигнала на сумматор И на величину транспортного запаздывани .In the case of using gaseous oxygen as an initiator in the polymerization process, i.e. during transport delay, generator 13 of the periodic pressure drops in reactor 1 outputs a signal to relay 9 after a signal to adder AND by the amount of transport delay.
