The utility model discloses a liquid drop recovery device of a hanging type chimney. The liquid drop recovery device comprises a grout tank (7) and a smoke entrance gap (63) formed in the upper end of a self-vertical inner cylinder (4) of the chimney. The liquid drop recovery device of the hanging type chimney is characterized by further comprising an annular liquid collecting board (62) and an expansion joint (8) which is horizontally arranged. One end of the liquid collecting board (62) is connected with the expansion joint (8), and the other end of the annular liquid collecting board (62) is connected with the upper end of the self-vertical inner cylinder (4) of the chimney. An annular liquid collecting groove (61) in the annular liquid collecting board (62) corresponds to the smoke entrance gap (63), an acid liquid discharging pipe (64) is connected to the annular liquid collecting board (62), and the lower end of the acid liquid discharging pipe (64) is communicated with the grout tank (7). The liquid drop recovery device can reduce the number of liquid drops carried by smoke and is simple in structure, high in efficiency, capable of saving energy and prolonging the service life of the expansion joint, and convenient to construct and overhaul.
