Abstract

Пар и жидкость параллельно проходят через вертикальный резервуар в каталитическом реакторе (1). Внутри резервуара расположена горизонтальная создающая препятствие потоку смесительная камера (8), в результате чего пар и жидкость проходят в вертикальном направлении через один или более входов в горизонтальную смесительную камеру. Смесительная камера состоит из круглых верхней (13) и нижней (14) стенок и цилиндрической боковой стенки (15). Внутри смесительной камеры расположены вертикальные дефлекторы (18, 19, 20). Эти дефлекторы образуют одно или более смесительных окон (21, 22). Весь технологический поток проходит через смесительное окно с высокой скоростью. После каждого смесительного окна следует Т-образное разветвление, где технологический поток разделяется на два потока, движущихся с меньшей скоростью. При переходе от высокой скорости потока в смесительном окне к меньшей скорости разделенных потоков создаются условия турбулентного потока. Для движущихся с меньшей скоростью разделенных потоков обеспечивается увеличенное время пребывания в смесителе для теплопередачи и массопередачи. Поток в смесительной камере движется в основном в горизонтальной плоскости. Поток на выходе смесителя уравновешен в отношении температуры и химического состава.Международная заявка была опубликована вместе с отчетом о международном поиске.Steam and liquid in parallel pass through a vertical tank in a catalytic reactor (1). Inside the tank there is a horizontal flow obstruction mixing chamber (8), with the result that steam and liquid flow in a vertical direction through one or more inlets to the horizontal mixing chamber. The mixing chamber consists of round upper (13) and lower (14) walls and a cylindrical side wall (15). Inside the mixing chamber are vertical deflectors (18, 19, 20). These baffles form one or more mixing ports (21, 22). The entire process stream passes through the mixing window at high speed. Each mixing window is followed by a T-shaped junction, where the process stream is divided into two streams moving at a lower speed. In the transition from a high flow rate in the mixing window to a lower velocity of the separated flows, the conditions for turbulent flow are created. For moving at lower speeds, the separated flows provide an increased residence time in the mixer for heat transfer and mass transfer. The flow in the mixing chamber moves mainly in the horizontal plane. The flow at the mixer outlet is balanced in terms of temperature and chemical composition. The international application was published along with an international search report.
