The invention discloses an anti-blocking flue gas waste heat recovery plate type heat exchange device and a heat exchanger thereof. The anti-blocking flue gas waste heat recovery plate type heat exchange device comprises a shell and a plurality of heat exchange plates which are installed in the shell and arranged at intervals, all the heat exchange plates are arranged in parallel, square convex fins are arranged on the front face and the back face of each heat exchange plate, the fins on the front face and the back face of each heat exchange plate are arranged in a staggered mode, and the fins on the front face and the back face of each heat exchange plate are arranged in a staggered mode. The distance between every two adjacent heat exchange plates is 2-4 times of the height of the fins. The distance between every two adjacent heat exchange plates is two to four times of the height of the fins, on one hand, flow channel blockage caused by smoke can be effectively prevented, on the other hand, transverse flow
