Description
токов сырь , подаваемых в верхнюю и нижнюю зоны питательной части колонны 3.currents of raw materials supplied to the upper and lower zones of the nutrient part of the column 3.
При небольших возмущени х по расходу и составу сырь , поступающего в колонну 3, мен етс разность температур в питательной части колонны, что воспринимает регул тор 4, и перемещением исполнительных механизмов 6 и 7 перераспредел ет потоки сырь в верхнюю и нижнюю зоны питающей части колонны, восстанавлива нарущенный режим, при этом выдерживаетс заданный состав получаемых продуктов и переменное задание, поступающее в регул тор 4 с анализатора 5 не измен етс . При больщих возмущени х (в пределах технологического регламента) по расходу и составу сырь за счет распределенности параметров по вл етс изменение состава паров в контрольной точке (например, на выходе из колонны), которое автоматически преобразуетс регулирующим анализатором 5 в корректирующий сигнал регул тору 4, который дополнительно воздействует на исполнительные механизмы б и 7, и заданный состав получаемых продуктов восстанавливаетс . Устройство сохран ет быстродействие и надежность измерени возмущений по расходу и составу сырь разностью температур в зоне питани и.With small disturbances in the flow rate and composition of the raw material entering the column 3, the temperature difference in the nutrient part of the column changes, which is perceived by the regulator 4, and by moving the actuators 6 and 7 redistributes the flow of raw material to the upper and lower zones of the supply part of the column restoring the abnormal mode, while maintaining the specified composition of the products obtained and the variable reference entering the controller 4 from the analyzer 5 does not change. With large disturbances (within the process schedule) for consumption and composition of the raw material, due to the distribution of parameters, a change in the vapor composition at the control point (for example, at the outlet from the column) appears, which is automatically converted by the regulating analyzer 5 into a correction signal to the regulator 4, which additionally affects the actuators B and 7, and the predetermined composition of the products obtained is restored. The device maintains the speed and reliability of measuring disturbances in consumption and composition of the raw material by the temperature difference in the feed zone and.
в то же врем , за счет наличи анализатора 5 состава поддерживает заданный состав получаемых продуктов.at the same time, due to the presence of the composition analyzer 5, it maintains the specified composition of the products obtained.
Предлагаемое устройство прощло опытную проверку на Краснодарском нефтеперерабатывающем заводе и обеспечило хорощее качество получаемых продуктов во всем диапазоне возмущений 10-30% по составу и количеству сырь .The proposed device passed an experimental test at the Krasnodar Oil Refinery and ensured the good quality of the products obtained in the entire range of disturbances of 10-30% in composition and quantity of raw materials.
Ожидаемый экономический эффект от использовани изобретени составл ет 24000 руб.The expected economic effect from the use of the invention is 24,000 rubles.
