Abstract

Замена различных секций распределителя 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 распределителя, а также диаметры питающих форсунок, присоединенных к этим отходящим патрубкам, изменяются для обеспечения равномерного потока сырьевого газа через эти компоненты. Распределитель можно подразделять на множество секций распределителя сырья, приспособленных для лучшего контроля реактора. Наконец, торцевые заглушки, ограничивающие дальние концы отходящих патрубков распределителя, можно обеспечивать форсунками для удаления любого катализатора аммоксидирования, который мог случайно достичь внутренней части распределителя.Replacing the various sections of the feed distributor used in a commercial ammoxidation reactor is facilitated by the use of gas tight quick disconnect fittings to attach the various sections of the spray arm to each other as well as to the reactor wall. In addition, the diameters of the outlet pipes in these sections of the distributor, as well as the diameters of the feed nozzles connected to these outlet pipes, are varied to ensure an even flow of the feed gas through these components. The distributor can be subdivided into a plurality of feed distributor sections adapted for better control of the reactor. Finally, end caps defining the distal ends of the distributor outlets can be provided with nozzles to remove any ammoxidation catalyst that might accidentally reach the interior of the distributor.
