Abstract
本发明的实施例提供了一种积垢过滤器、积垢过滤设备和大型固定床反应器，涉及石油炼制和化工设备领域。该积垢过滤器包括相互连接的顶筒和底筒，顶筒的侧壁开设有第一通孔，底筒包括内筒和套设于内筒外侧的外筒，内筒和外筒之间形成环形空腔，顶筒内和环形空腔内均填充有保护剂和 / 或催化剂，内筒的内部形成供过滤后的液体排出的中心通道；外筒分为上部筒和下部筒，上部筒设置有第二通孔，下部筒设置有第三通孔，第二通孔的孔径小于第三通孔的孔径。该积垢过滤器的顶筒可以起到缓流和初步过滤的作用，而底筒下部空隙度较大，物料会持续缓慢流动，液体动态沉积，不易堵塞。该积垢过滤器安装于反应器的封头内，充分利用封头空间，提升了装填效率。
