(54) СПОСОБ АВТОМАТИЧЕСКОГО РЕГУЛИРОВАНИЯ ПРОЦЕССА ЭМУЛЬСИОННОЙ ПОЛИМЕРИЗАЦИИ ВИНИЛХЛОРИДА(54) METHOD FOR AUTOMATIC REGULATION OF THE PROCESS OF EMULSION POLYMERIZATION OF VINYL CHLORIDE
ветствуюшую рубашку охлаждени попимериэатора ..Cooling shirt on a popmerieator ..
Не чертеже представлена блок-схема системы регулировани , реализующей описываемый способ.The drawing does not show the block diagram of the control system that implements the described method.
Способ автоматического регулировани процесса эмульсионной полимеризашш винилхлорида осуществлиот следующим образом.A method for automatically controlling the emulsion polymerization process of vinyl chloride is carried out as follows.
Вннилхлорид и эмульсионную воду подают сверху в полый полимеризатор 1. Ти шературу в полом полимеризаторе 1 по его высоте измер ют датчиками 2., 3, 4, 5 температуры и регулируют с помощью регул торов в, 7, ,8, 9, воздействующих на клапаны 10, 11, 12, 13, измен ющих расход воды в соответствующие рубашки охлаждени поЛО1Х полимеризатора 1.The innyl chloride and emulsion water are fed from above into the hollow polymerizer 1. The sherature in the hollow polymerizer 1 is measured at its height by sensors 2., 3, 4, 5 and is regulated by regulators b, 7, 8, 9 acting on the valves 10, 11, 12, 13, which change the flow of water into the respective cooling shirts of the POLOX polymeriser 1.
Циркул ци охлаждающей воды осуществл етс с помощью насоса 14.The circulation of cooling water is carried out by means of a pump 14.
Датчиками 15 и 16 температуры измер ют температуру воды, отход щей от полого полимеризатора 1 и подводимой к нему.Temperature sensors 15 and 16 measure the temperature of the water leaving the hollow polymerizer 1 and supplied to it.
Сигналы от датчиков температуры 15 и 16 через функциональные блоки 17 и 18 подают в регул тор 19, с помощью которого регулируют количество тепла, снимаемое хладагентом с полого полимеризатора 1, воэдействиол на клапан 2 О, установленный на трубопроводе подачи охлажденЕЕой воды в насос 14.The signals from temperature sensors 15 and 16 through the functional blocks 17 and 18 are fed to the controller 19, with which they regulate the amount of heat removed by the refrigerant from the hollow polymerizer 1 to act on the 2 O valve installed on the cooling water supply pipe to the pump 14.
Датчиком 21 измер ют толЩ1гау пленкн полимера на внутренних стенках полого полимеризатора 1 и регулируют ее величину с помощью регутгатора 22, корректиру задание реттп тору 19. Непрерывное изменение толщины нарастани пленки полимера на стейках полого полимеризатора 1 и корректировка расхода охлажденного хладагейта в зависимости от иэл енени толщины нарастани пленки полимера дает возможность повьюить точность стабилизации г&лп&р туры в полом полимеризаторе 1, что позволит получить полимер с заданным мо;лекул рным есом и свойствами.The sensor 21 measures the thickness of polymer films on the inner walls of the hollow polymerizer 1 and regulates its value with the help of a regugger 22, corrects the setting of the retptor 19. Continuous change in the film thickness of the polymer film on the steaks of the hollow polymerizer 1 and the flow rate of the cooled refrigerant depending on the actual thickness the growth of the polymer film makes it possible to turn up the accuracy of stabilization of g & l & r in the hollow polymerizer 1, which will make it possible to obtain a polymer with a given molecular weight and property you.
