A liquid-separate-film device for sucking and exhausting fume, includes a pressured liquid outlet, which is located on one side of the diffusing surface of the fume's source and parallel with the diffusion surface, and a suctional liquid inlet connected with a suction-produce device, which is located on the opposed side and also parallel with the diffusion surface. The liquid flowing from the said outlet to said inlet forms liquid-separate film which can separate the fume's source from outer air by the fume's path between the said outlet and said inlet. The invention can be applied to bi-directional separation in the industry and exhausts the fume on the fume's source. The complex civil stove using the inventive device can exhaust the air downwards, then clear the polluted fume thoroughly.
