Abstract

Замена различных секций разбрызгивателя сырья, используемого в промышленном реакторе аммоксидирования, облегчается путем использования газонепроницаемых быстроразъемных фитингов для прикрепления различных секций разбрызгивателя друг к другу, а также к стенке реактора. Кроме того, диаметры отходящих патрубков в этих секциях разбрызгивателя, а также диаметры питающих форсунок, присоединенных к этим отходящим патрубкам, изменяются для обеспечения равномерного потока сырьевого газа через эти компоненты. Разбрызгиватель можно подразделять на множество секций разбрызгивателя сырья, приспособленных для лучшего контроля реактора. Наконец, торцевые заглушки, ограничивающие дальние концы отходящих патрубков разбрызгивателя, можно обеспечивать форсунками для удаления любого катализатора аммоксидирования, который мог случайно достичь внутренней части разбрызгивателя.Replacing the various sprinkler sections of the raw materials used in an industrial ammoxidation reactor is facilitated by using gas-tight quick-disconnect fittings to attach the various sprinkler sections to each other, as well as to the wall of the reactor. In addition, the diameters of the exhaust nozzles in these sections of the sprinkler, as well as the diameters of the feed nozzles attached to these exhaust nozzles, are changed to ensure a uniform flow of raw gas through these components. The sprinkler can be subdivided into a plurality of raw material sprinkler sections adapted for better reactor control. Finally, the end caps limiting the far ends of the sprinkler outlets can be provided with nozzles to remove any ammoxidation catalyst that could accidentally reach the inside of the sprinkler.
