Description

Предмет изобретени Subject invention

Устройство дл  автоматического регулировани  ректификационной колонны, содержащее датчики расходов входного и выходных потоков, анализатор качества входного нотока , регул тор соотношени  и реле нереключени , отличающеес  тем, что, с цельюA device for automatic control of a distillation column, comprising input and output flow sensors, an input quality analyzer, a ratio controller, and a non-switching relay, characterized in that

повышени  точности и надежности работы устройства, оно снабжено кЕюрум-элементом и вычислительными блоками, входы которых соединены с соответствующими выходами датчиков расходов, а выходы - со входами кворум-элемента, выход которого св зан с рходом регул тора соотношени .increase the accuracy and reliability of the device, it is equipped with a cel-element and computing units, the inputs of which are connected to the corresponding outputs of the flow sensors, and the outputs - to the inputs of the quorum-element whose output is connected to the ratio regulator.
