Abstract
The invention discloses a support device for heat exchange pipe sets of a pyrolysis kiln. The support device comprises an H-shaped support arranged on the inner wall of a rotary kiln barrel body. The H-shaped support is composed of two edge frames and a cross rod connecting the two edge frames. Pin shaft holes are distributed in each edge frame at intervals. Multiple interval blocks are arranged in a rectangular space in the height direction, wherein the rectangular space is defined by the two edge frames and the cross rod and is far away from the inner wall of the rotary kiln barrel body. A semicircular concave end and a flat plate end which can be connected with the adjacent interval blocks are arranged on each interval block. The semicircular concave ends on every two adjacent interval blocks are in butt joint with each other to form circular holes allowing heat exchange pipes to penetrate. An annular groove is formed in the flat plate end of each interval block in the length direction. The flat plate ends of every two adjacent interval blocks are in butt joint with each other to form through holes allowing pin shafts to penetrate. The through holes correspond to the pin shaft holes in the edge frames in position. The support device for the heat exchange pipe sets of the pyrolysis kiln is high in reliability, convenient to mount and overhaul and capable of guaranteeing long-term efficient operation of equipment.
