Известный способ автоматического управлени процессом ректификации смесей путем изменени расхода орошени в зависимости от температуры и давлени верха колонны, расходов целевого продукта, острого орошени и вод ного пара не обеспечивает заданного состава продуктов.The known method of automatically controlling the process of rectification of mixtures by varying the flow rate of irrigation depending on the temperature and pressure of the top of the column, the flow rates of the target product, acute irrigation and water vapor does not provide the desired composition of products.
С целью устранени указанного недостатка расход орошени регулируют в зависимости от давлени в рефлюксной емкости, расхода сырь и температуры острого орошени .In order to eliminate this drawback, the flow rate of the reflux is controlled depending on the pressure in the reflux tank, the consumption of raw materials and the temperature of the acute irrigation.
На чертеже представлена схема устройства, реализуюшего способ.The drawing shows a diagram of the device that implements the method.
На выход дроссельного сумматора / поступает сигнал с датчика 2 расхода верхнего продукта, датчика 3 острого орошени , датчика 4 давлени верха колонны и датчика 5 давлени в рефлюксной емкости. Суммарный сигнал с выхода дроссельного сумматора / подают на инвертор 6, где его инвертируют и подают на дроссельный сумматор 7, на входы которого поступают сигналы от датчика 8 температуры верха колонны, датчика 9 температуры острого орошени , датчика 10 расхода сырь и датчика // расхода пара. Выходной сигнал с дроссельного сумматора 7 соответствует температуре раздела фракций. Он поступает на вторичный прибор 12, по которому ведут наблюдени за ходом процесса, и на вход регул тора 13, который, воздейству на исполнительный механизм 14 расхода острого орошени , восстанавливает заданное значение температуры раздела фракций.The output of the choke adder / receives a signal from the overhead flow sensor 2, the spraying sensor 3, the column top pressure sensor 4 and the pressure sensor 5 in the reflux tank. The total signal from the output of the throttle adder / serves to the inverter 6, where it is inverted and fed to the throttle adder 7, the inputs of which receive signals from the sensor 8 of the top of the column, the sensor 9 temperature acute irrigation, sensor 10 consumption of the sensor and // steam consumption . The output signal from the throttle adder 7 corresponds to the temperature section of the fractions. It enters the secondary device 12, through which the process is monitored, and at the input of the regulator 13, which, acting on the flow controller of the acute irrigation, restores the set value of the fractional separation temperature.
