一种用于连续重整反应器催化剂输送和密封的下部料斗
摘要：
本实用新型公开了一种用于连续重整反应器催化剂输送和密封的下部料斗。包括：筒体、头盖和下部锥体；头盖和下部锥体分别设置于筒体上下两端并与筒体固定连接；头盖中心设置有套筒和催化剂进口，所述套筒伸入到筒体内部；套筒上设置有套筒盖，套筒盖中心设置有氢气/氮气入口，氢气/氮气入口伸入到套筒内部，氢气/氮气入口的底部高于套筒底部；下部锥体底部设置有催化剂出口。本实用新型可以对离开连续重整反应器的催化剂输送系统进行有效的密封，使得反应物料不能进入催化剂循环输送系统，满足正常操作和安全生产的要求。
摘要（英）：

The utility model discloses a lower hopper for conveying and sealing a catalyst from a continuous reforming reactor. The lower hopper comprises a barrel body, a head cover and a lower cone body, wherein the head cover and the lower cone body are arranged at the upper end and the lower end of the barrel body respectively and are fixedly connected with the barrel body; a sleeve barrel and a catalyst inlet are arranged in the center of the head cover; the sleeve barrel extends into the barrel body; a sleeve barrel cover is arranged on the sleeve barrel; a hydrogen/nitrogen inlet is formed in the center of the sleeve barrel cover and extends into the sleeve barrel; the bottom of the hydrogen/nitrogen inlet is higher than that of the sleeve barrel; and a catalyst outlet is formed in the bottom of the lower cone body. The lower hopper can effectively seal a catalyst conveying system away from the continuous reforming reactor, thereby preventing reaction materials from entering a catalyst circulation conveying system. Therefore, the requirements of normal operation and safety production are satisfied.
