Abstract: Изобретение относится к роторным аппаратам для проведения абсорбционных и ректификационных процессов, в частности для ректификации в условиях вакуума термически нестойких продуктов. Недостатком известных конструкций является недостаточно высокая эффективность массообмена и низкая производительность по жидкой фазе. Цель изобретения - увеличение эффективности массообмена и производительности контактного устройства. Поставленная цель достигается тем, что на пакете усеченных конусов, обращенном вершинами вниз, вверху, на основаниях конусов закреплены горизонтальные диски, с внешней стороны которых установлен вертикальный перфорированный цилиндр, на котором по высоте, в пределах каждого кругового распределительного кармана выполнены отверстия в виде щелевых горизонтальных прорезей, расположенных одна от другой на расстоянии по высоте. Существенным отличием является оборудование пакета конусов горизонтальными дисками и вертикальным перфорированным цилиндром, образующим круговые распределительные карманы. В результате увеличивается число слоев распыления жидкости и возрастает поверхность контакта фаз. 2 з.п. ф-лы, 3 ил.
