再生器内外篮Inner Basket \Outer Basket

 外蓝是径向流反应器内件系统网的重要组成部分,与壳体内壁平行,其内表面限定催化剂床层的外侧。通常安装于径向流反应器内,用于介质流体的收集和分布。顶部盖板用于封闭内网与外蓝之间的空隙,介质流向可由内而外或由外而内。外蓝整体通过设备上口安装于壳体内,坐落于设备筒体内壁的支撑圈上。既要能够经受住催化剂床层生产的高强度的机械压力,也不会受到容器内壁本身的挤压干扰。因为外蓝的整体独立式结构,壳体内壁与其形成更大的空间,因此具有更高的介质处理能力。显著提高工艺效率。一般用于CCR、重整、氨合成塔、苯乙烯、燃气处理等装置。 Outer baskets are the outer screen components of a radial flow system。 Their general shape is extending parallel to the inner vessel wall。 Their surface delimits the outer side of the catalyst bed。 They are usually installed inside vertical reactors and distribute or collect the flow。Cover deck is closing the gap between inner screen component and outer baskets。 Flow direction can be outwards or inwards。 The outer basket is one single piece equipment that has to be installed over the full vessel cross section。 The equipment is self standing on a support ring attached to the vessel shell。As the outer basket is self-standing, it allows wider distance towards the inner vessel surface, therefore, higher flow capacity。 The annular gap remains constant whichever direction the flow goes。 As being apart from the vessel shell, it has to withstand the full mechanical stress given by the catalyst bed and, in the same way, it is not compressed by the stress transferred from the vessel shell。
