Abstract

Непропорциональное перемешивание реагентов, а также местные участки перегрева в промышленном реакторе получения акрилонитрила можно значительно снижать, если расстояние между системой 16 разбрызгивателя и вентиляционной решеткой 14 регулируют в пределах 6-24 дюймов (от ~15 до ~61 см), предпочтительно 8-12 дюймов (от ~20 до ~30,5 см). Кроме того, проблемы перемещения вентиляционной решетки по или с опоры и механическое повреждение вентиляционной решетки можно устранять практически полностью посредством модифицированной системы присоединения вентиляционной решетки к стенкам реактора, а также ее внутренним опорам.Disproportionate mixing of reagents, as well as local overheating areas in an industrial acrylonitrile reactor, can be significantly reduced if the distance between the sprinkler system 16 and the ventilation grill 14 is adjusted within 6-24 inches (from ~ 15 to ~ 61 cm), preferably 8-12 inches (from ~ 20 to ~ 30.5 cm). In addition, the problems of moving the ventilation grille up or down from the support and mechanical damage to the ventilation grille can be almost completely eliminated by means of a modified system for attaching the ventilation grille to the walls of the reactor, as well as its internal supports.
