The invention relates to the technical field of purification equipment, in particular to a reversible catalytic burner. The reversible catalytic burner comprises a valve controller, a PLC, first inertia heat-storage packing, a catalyst burning bed, second inertia heat-storage packing, a preheating device, an organic waste gas inlet main pipe and an exhaust main pipe. According to the reversible catalytic burner, organic matter in organic waste gas can be removed in a burning way, and heat generated by the organic waste gas can be utilized to the greatest extent in the burning process of the organic waste gas; energy consumption in the whole purification process is reduced, and secondary pollution is avoided; the stability is high, and the applicable organic waste gas concentration range is wide; and the reversible catalytic burner is compact and simple in structure and has broad application prospects. In addition, the reversible catalytic burner is reasonable in structural design, convenient and fast to use and maintain, and suitable for application and popularization.
