The invention relates to a waste heat sharing intensive tobacco flue-curing house, which is formed by connecting a plurality of tobacco flue-curing rooms into a whole. Adjacent tobacco flue-curing rooms are spaced through longitudinal common partition walls; the back end of each tobacco flue-curing room is provided with a heating chamber which corresponds to the tobacco flue-curing room; the tobacco flue-curing room and the heating chamber are spaced through a transverse common partition wall; a humidity reducing passage and a waste heat sharing passage which hermetically communicates the tobacco flue-curing rooms are arranged in each tobacco flue-curing room; and the waste heat sharing passage consists of a waste heat heating passage and a waste heat dampening passage which are firmly spaced through a waste heat sharing passage partition wall and are communicated with the humidity reducing passage respectively. The waste heat sharing connected intensive tobacco flue-curing house has the advantages of simplifying and improving the building structure of the flue-curing house, lowering construction cost, saving energy and reducing consumption, lowering curing cost and curing labor, and enhancing heat cyclic utilization ratio and stably enhancing the quality of the flue-cured tobacco, along with scientific structure, reasonable layout, convenient operation, and high performance.
