The utility model discloses a chimney waste heat recovery and utilization device for a bulk curing bran for tobacco. The chimney waste heat recovery and utilization device structurally comprises a cold air drainage tube, a countercurrent flow heat exchange tube and a hot air drainage tube which are sequentially connected to form an air channel; the cold air drainage tube is fixed outside a chimney through a pipeline fixator; the countercurrent flow heat exchange tube is fixed inside the chimney through a pipeline fixator; the hot air drainage tube is fixed in a heating chamber through a pipeline fixator; an air outlet of the hot air drainage tube is over against a circulating fan arranged in the heating chamber; an air inlet of the cold air drainage tube is provided with a cold air inlet door and an air door opening adjuster. According to the chimney waste heat recovery and utilization device, the waste heat of the chimney is sufficiently utilized and the energy consumption in the tobacco leaf curing process is reduced.
