Description
Изобретение относитс к конструкции аппаратов дл реакции полимеризации и со- полимеризации олефиновых и диеновых углеводородов и может быть использовано, в частности, дл синтеза бутилкаучука.The invention relates to the construction of apparatus for the reaction of polymerization and copolymerization of olefinic and diene hydrocarbons and can be used, in particular, for the synthesis of butyl rubber.
Целью изобретени вл етс повышение производительности полимеризатора и улучшение качества получаемого полимера .The aim of the invention is to increase the productivity of the polymerizer and improve the quality of the polymer produced.
На чертеже схематично изображен полимеризатор , вертикальный разрез.The drawing schematically shows a polymerization, vertical section.
Полимеризатор состоит из корпуса 1, в котором по оси установлено перемешивающее устройство в виде вала 2, на котором закреплены мешалки 3-5, Мешалки приводитс во вращение от привода 6. По периферийным зонам аппарата установлены трубные пучки 7, через которые производитс прокачка хладагента при помощи штуцеров 8 и 9. Штуцеры 10 и 11 на нижнем днище аппарата служат соответственно дл подачи шихты и катализатора в реактор, аThe polymerizer consists of a housing 1, in which an axially mounted mixing device in the form of a shaft 2 on which the stirrers 3-5 are mounted. The agitators are driven into rotation by the actuator 6. The tube bundles 7 are installed in the peripheral zones of the apparatus, through which the refrigerant is pumped through fittings 8 and 9. Fittings 10 and 11 on the bottom of the apparatus serve respectively for feeding the charge and catalyst to the reactor, and

При работе реактора мешалки 5 создают необходимую высокую степень перемешивани основной части реакционной массы и высокую скорость обтекани ею трубных пучков 7 и тем самым инiенсивь ;и отвод тепла реакции. Мешалка 3, установленна на рассто нии от днища не боне, чем 0,1-0,5 диаметра мешалки обеспечивает наиболее интенсивное предварительное смешение межцу собой потоков входчщи в аппарат через штуцеры 10 и 11, т с- шихты и катализатора. Именно это условие вл етс реиыющим дл пол/чени полимера с заданными свойствами, прежде всего, тре буемым молекуп рно-массовым распределением . Мешалка 4, установленна в том же интервале рассто ний (0,1-0,5 диаметра вешалки от серхнего днища корпуса, пр дотв- ращает застой полимерных частиц ь верхней зоне реактора, гооисход щш- вследствие того, что плотность полимераWhen the reactor is operating, the stirrers 5 create the necessary high degree of mixing of the main part of the reaction mass and the high flow rate of tube bundles 7 around it, and thus, the intensity of the reaction heat. The agitator 3, installed at a distance from the bottom not less than 0.1-0.5 diameters of the agitator, provides the most intensive preliminary mixing of the flows between the bodies through the fittings 10 and 11, tons of mixture and catalyst. It is this condition that is responsible for obtaining a polymer with specified properties, first of all, the required molecular mass distribution. The stirrer 4 installed in the same spacing distance (0.1–0.5 of the diameter of the hanger from the bottom of the casing, prevents stagnation of polymer particles in the upper zone of the reactor, because the source is too thin).

меньше, чем плотность жидкой фазы. Тем самым исключаетс агломераци полимера в указанной зоне реактора, что обычно неизбежно приводит к забивке выводного штуцера 12, принуждающей к прекращению процесса полимеризации в аппарате. Таким образом, указанное расположение мешалки в верхней зоне реактора позвол ет существенно увеличить длительность циклов полимеризации в данном аппарате по сравнению с циклами в известном реакторе и с ответственно увеличить его производительность .less than the density of the liquid phase. This prevents agglomeration of the polymer in the specified zone of the reactor, which usually inevitably leads to clogging of the outlet nozzle 12, which forces the polymerization process to stop in the apparatus. Thus, this arrangement of the agitator in the upper zone of the reactor makes it possible to significantly increase the duration of the polymerization cycles in this apparatus as compared to the cycles in the known reactor and to increase its productivity accordingly.
