Abstract: Изобретение относится к химическому, фармацевтическому оборудованию, а именно представляет собой трубную камеру отклонения потока, непрерывный проточный реактор и систему непрерывных проточных реакций с системой управления. Непрерывный проточный реактор включает в себя: корпус, в котором имеются вход в межтрубное пространство и выход из межтрубного пространства, сообщающиеся с внутренней полостью корпуса. Нижний и верхний концы упомянутого корпуса подсоединены к трубным решеткам и блокам кольцевания, внутри упомянутого корпуса установлен пакет реакционных трубок. Пакет реакционных трубок включает в себя несколько реакционных трубок, нижний и верхний концы каждой из которых проходят и жестко закрепляются в трубной решетке, упомянутые реакционные трубки одна за другой последовательно соединяются посредством блока кольцевания. Технический результат – повышение эффективности работы всех элементов системы: трубной камеры отклонения потока, непрерывного проточного реактора и системы непрерывных проточных реакций с системой управления. Это достигается за счет того что, с одной стороны, существенно совершенствуется технологический процесс реакции в сравнении с аналогичным объемом традиционного реактора, с другой стороны, появляется возможность: реагенту при низкой скорости потока получать высокое число Рейнольдса и значительно повысить турбулентный эффект, причем одновременно с непрерывной проточной реакцией обеспечивается непрерывное смешивание. При этом с одной стороны, есть возможность в реальном времени контролировать состояние каждой фазы реакции, с другой стороны - упростить установку и сборку. 4 н. и 7 з.п. ф-лы, 9 ил.
