The invention discloses a fluorescent lamp recovery device. The fluorescent lamp recovery device includes a sealing box, and a fixing mechanism, a cutting mechanism, a crushing mechanism and a filtering mechanism arranged in the sealing box. The fixing mechanism includes an accommodation cavity and a clamping assembly fixed in the accommodation cavity. The cutting mechanism includes a grinding sheet and a support. The grinding sheet is in rotary connection with the support. The grinding sheet is corresponding to the peripheral side of a lamp tube of the fluorescent lamp. The crushing mechanism includes a receiving board and a round roller. The receiving board is used for holding lamp tube debris. The round roller is connected to a side, adjacent to the cutting mechanism, of the receiving board in a rolling manner. The filtering mechanism includes a bending pipeline, a filtering net and an exhaust fan. The bending pipe includes an air inlet and an air outlet. Both of the air inlet and the air outlet penetrate through the side wall of the accommodation cavity. The filtering net is arranged in the air inlet. The exhaust fan is mounted in the bending pipeline.
