Description
技术领域
本发明涉及DBD反应器领域,尤其涉及一种电极旋转式DBD反应器。
背景技术
介质阻挡放电(DBD)是最常见的非平衡等离子体的发生方式之一,该放电方式是在电极之间插入绝缘介质,能避免放电向弧光、火花放电转化。大气压空气条件下的DBD已经在工业上得到广泛应用,涉及污水处理、空气净化、包装印染、锂电池等多个领域。材料表面改性是DBD的重要应用之一,它通过DBD产生的等离子体与材料表面发生一系列物理、化学反应,改变材料表面的粗糙度,引入亲水性官能团,进而提高材料的亲水性、润湿性、印染性等特性。目前,工业上应用的主要是刀排-滚筒式反应器,这类反应器便于连续化生产,但同平行板-板式反应器相比,气隙调节困难,放电均匀性差。平行板-板直线运动式反应器,气隙调节方便,电极运动速度可控但是精度较低,占地空间大,环境气体控制困难。
中国专利201811346288 .2公开了一种板式DBD反应器,包括框架,框架的顶部设有垂直升降平台,所述垂直升降平台包括固定在框架顶部的基座,基座的底部设有X型折叠伸缩架,X型折叠伸缩架的底端连接有升降板;所述升降板的底部设有高压绝缘块,高压绝缘块的底部设有高压电极板,高压电极板的底部设有高压极介质板;所述垂直升降平台的下方设有滑台,所述滑台上设有滑动架,滑动架的上方设有低压电极板,低压电极板的顶部设有低压极介质板。本发明可以根据需要对高压电极板和低压电极板之间的距离进行调节变换,以满足对不同放电气隙的DBD反应情况的试验分析,具有适应性好、精度高、易操作的特点。
上述专利采用移动式的电极板结构,这样导致移动范围较小且低压电极板的速度控制精确度差,占地空间大,无法形成对环形气体的控制。
发明内容

进一步的,所述框架的四周通过绝缘的透明玻璃密封,框架的顶端与框架的底端通过金属板材密封。
进一步的,所述框架的上腔体的密封板材上设置有进气口、高压电极板接线口和低压电极板接线口;所述框架的下腔体的密封板材上设置有旋转电机接线口和出气口。
进一步的,所述旋转电机的输出端通过一绝缘块与压力轴承相连。
本发明的优点在于:
1)本发明中高压电极板数量可变且安装方便,结合低压电极板转速,可以在保证总的处理时间一定的情况下实现多时段处理,单个时段处理时间及间歇时间均可控,形式多样。
