The invention relates to a chimney non-metal expansion joint, and relates to the technical field of expansion joints, the chimney non-metal expansion joint comprises a first connecting ring and a second connecting ring, and the first connecting ring and the second connecting ring are arranged at the ends, close to each other, of two sections of chimneys correspondingly; the two ends of the built-in fluororubber ring belt are detachably connected to the first connecting ring and the second connecting ring through two sets of connecting mechanisms correspondingly; one end of the flow guide plate is arranged on the first connecting ring, the other end of the flow guide plate extends to the second connecting ring, and the flow guide plate is located on the side, close to the interior of the chimney, of the built-in fluororubber ring belt. The expansion amount of the chimney is absorbed through the built-in fluororubber ring belt, meanwhile, direct contact between flue gas and the built-in fluororubber ring is avo
