参照图1-3,一种单壁碳纳米管流化床反应装置,包括支撑板1以及固定安装在支撑板1上的反应壳体5,支撑板1上固定安装有气体预热罐2,气体预热罐2和反应壳体5相互连通,反应壳体5一侧安装有储料罐4,反应壳体5内固定连接有安装块,安装块上转动设置有转动轴6,转动轴6上固定连接有第一扰流片7以及凸轮9。

限位槽内固定连接有弹簧10,弹簧10和限位杆16固定连接,限位杆16在限位槽内滑动时,由于弹簧10一端和限位槽内壁固定连接,另一端和限位杆16固定连接,弹簧10就会随着限位杆16的移动而发生形变,套筒14一端固定连接有挤压板15,挤压板15和凸轮9配合使用,凸轮9转动的过程中,会和挤压板15接触,并且对其具有一定的挤压作用力,在挤压作用力的作用下,挤压板15就会发生移动。
反应壳体5一侧设置有还原仓,还原仓通过循环管3和气体预热罐2连接,通过还原仓的催化还原后,多余的气体就会通过循环管3进入气体预热罐2内,实现气体的循环利用,支撑板1上固定连接有防滑垫,防滑垫用于提高支撑板1的稳定性,由于防滑垫和接触面之间的摩擦力较大,可以防止支撑板1和接触面之间发生相对滑动,使支撑板1以及反应壳体5更加稳定,有利于单壁碳纳米管的稳定生产。
本发明中,首先将气体通入气体预热罐2内预热,预热后的气体进入反应壳体5内,并且打开安装块内的伺服电机开关,由于伺服电机驱动端和转动轴6固定连接,在伺服电机的驱动作用下,转动轴6就会和安装块发生相对转动,第一扰流片7随着转动轴6一起转动,第一扰流片7转动的过程中,可以对通入的气体进行扰流,使气体分布更加均匀,凸轮9在转动的过程中,会与挤压板15接触并对其进行挤压,在凸轮9的挤压作用下,挤压板15以及套筒14就会水平移动,限位杆16在限位槽内滑动,由于弹簧10一端和限位槽内壁固定连接,另一端和限位杆16固定连接,弹簧10就会随着限位杆16的移动而发生形变,套筒14与螺纹杆13发生相对滑动的过程中,第二扰流片8就会和螺纹杆13螺纹连接,从而使得第二扰流片8不断的发生转动,更加有利于对气体的扰流,使气体分布的更加均匀,在第一扰流片7以及第二扰流片8的共同扰流作用下,可以使反应壳体5内气体均匀的分配,反应壳体5内的单壁碳纳米管生长的更加均匀,从而可以使单壁碳纳米管的产量较高,更加有利于单壁碳纳米管的生产。
在本发明中,除非另有明确的规定和限定,术语“安装”、“相连”、“连接”、“固定”等术语应做广义理解。
以上所述,仅为本发明较佳的具体实施方式,但本发明的保护范围并不局限于此,任何熟悉本技术领域的技术人员在本发明揭露的技术范围内,根据本发明的技术方案及其发明构思加以等同替换或改变,都应涵盖在本发明的保护范围之内。
