The invention discloses an automatic fan blade water mist dust collector. The dust collector comprises a dust collecting pipe connected with an outlet of an induced draft fan. First-grade fan blades and second-grade fan blades which are coaxial are arranged in the dust collecting pipe. The first-grade fan blades and the second-grade fan blades are arranged in the wind direction at intervals. The outlet of the dust collecting pipe is connected with a settling chamber. A water pool is arranged at the bottom of the settling chamber. The outlet of the settling chamber is connected with an exhaust pipe. A nozzle facing the windward side of the first-grade fan blades is arranged in the dust collecting pipe. The dust collector comprises a water pump. The water pump draws water in the water pool and the water is sprayed from the nozzle to the fan blades. The fan blades rotate to atomize water. Dust in tail gas is attached to the atomized steam, goes into the settling chamber for settlement and finally falls at the bottom of the water pool. The purified tail gas is discharged from the outlet of the settling chamber through the exhaust pipe. The dust collector employs a water mist dust collection mode, freely-rotated fan blades are arranged in the dust collecting pipe and are driven by wind power of the induced draft fan directly, and additional driving devices are not needed. Energy is saved, the structure is simple, and usage is convenient.
