Description
本发明涉及一种反应器,具体涉及一种多程径向反应器。
近年在煤化工领域,径向反应器方兴未哀,以其反应效率高、体积小倍收欢迎。但是目前投入使用径向反应器都是单程路径,应用于某些场合,存在反应路径太短,合成气流速慢,从而导致反应不充分问题。
发明内容
为解决上述问题,本发明提出一种合成气多程径向流动的多程径向反应器。
本发明的技术方案:
一种多程径向反应器,所述多程径向反应器包括外壳,所述外壳内设置有上管箱、下管箱以及若干换热管,上管箱固定连接在外壳上端,下管箱固定连接在外壳下端,所有换热管均分布在上管箱与下管箱之间,由内至外围成若干圈,每个换热管的上端与上管箱固定连接,并伸入上管箱内,连通上管箱内部空间,每个换热管的下端与下管箱固定连接,并伸入下管箱内,连通下管箱内部空间,共同构成换热管束;所述上管箱顶部穿过外壳伸出一段,其上设置有冷媒出口,所述下管箱底部穿过外壳伸出一段,其上设置有冷媒进口;所述外壳内还设置有内筒、外筒,内筒固定安装在换热管束内部,覆盖换热管束内圈,其两端分别与上管箱、下管箱固定连接,外筒固定安装在换热管束外部,覆盖换热管束外圈,其上端安装有挡气圈、下端与外壳通过密封连接,将所述外壳内部空间即壳程空间分成三个部分,位于内筒与上管箱、下管箱之间的筒内空间、位于内筒与外筒之 间的反应层空间、位于外筒与外壳之间的夹层空间;所述内筒、外筒由上至下交替为透气段、不透气段;所述反应层空间内填充催化剂,催化剂没过换热管束;所述外壳顶部设置有混合气进口、底部设置有合成气出口,混合气进口、合成气出口分别连通反应层空间;在所述内筒内固定连接有若干内筒隔板,将筒内空间分成上下若干个小空间,每个小空间所在位置对应的内筒和外筒的透气段;在所述内筒、外筒密布孔眼构成所述透气段。
工艺流程:
合成气从合成气进口进入反应层空间,向下进入催化剂中走一小段轴向路径,到达内筒的透气段,由于气体有走最小阻力路径的特点,所以绝大部分气体转弯走径向进入筒内空间;然后,在不透气段向下走一小段轴向,又来到透气段,由于内筒隔板的阻挡,气流又转弯走径向经过催化剂进入外层空间,气体到达外层空间向上走不通,只能向下走过不透气段,到达透气段后又转弯走径向经过催化剂后再次进入筒内空间;气流向下走一段后又转弯走径向进入催化剂中,然后在催化剂中向下走一段轴向从合成气出口流走;在大部分气体走出S形路径的同时,有少量气从不透气段的催化剂中直接走轴向向下;多程径向流动,提高了线速度,使反应更充分;
另一路流体是冷媒,从冷媒入口进入下管箱,然后从各换热管内向上流动,进入上管箱,最后从冷媒出口流走;冷媒与换热管外的催化剂进热交换,不断地将反应所产生的热量带走,从而保证反应区的温度平衡。
所述外壳由外壳下封头、外壳筒体、外壳上封头连接构成,外壳下封头、外壳筒体、外壳上封头共同围成所述壳程空间。
所述上管箱由上管箱封头、带凸肩上管箱筒节、上管箱筒节、上异管板连接构成,上管箱封头、带凸肩上管箱筒节、上管箱筒节、上异管板共同围成所述上管箱内部空间;
所述下管箱由下管箱封头、带凸肩下管箱筒节、下管箱筒节、下异管板连接构成,下管箱封头、带凸肩下管箱筒节、下管箱筒节、下异管板共同围成所述上管箱内部空间;
在所述上异管板、下异管板上均密布小孔,所述换热管上端穿过上异管板上的小孔,并与上异管板焊接,所述换热管下端穿过下异管板上的小孔,并与下异管板焊接。
所述反应层空间内的下部还填充有瓷球,即瓷球分布在换热管束下方;在所述外壳顶部设置有装催化剂口、底部设置有卸催化剂口,装催化剂口、卸催化剂口分别连通反应层空间;所述所述合成气出口上安装有瓷球挡板,遮挡住合成气出口,使瓷球不会漏出。
所述反应器还包括裙座,裙座置于外壳下方,支撑外壳,并与外壳固定连接;
所述裙座侧面设置有检查孔。
所述下管箱底部设置有下管箱人孔。
所述外壳侧壁设置有人孔。
所述上管箱底部设置有内部检修孔,内部检修孔连通上管箱内部空间与筒内空间。

本发明优点是,设计合理,结构简单,让合成气多程径向流动,从而提高了线速度,使反应更充分。
