摘要（英）：

The utility model discloses a device for removing PM2.5 (particle matter less than 2.5 micrometers in diameter) in smoke, which comprises a removal tower, a wet type electric precipitator and a wetting spraying device. A smoke inlet end is arranged at the lower portion of the removal tower and is provided with a particle charged area and a mixing coagulation area. The particle charged area is divided into a positive corona discharge area and a negative corona discharge area, a positive electrode is arranged in the positive corona discharge area, and a negative electrode is arranged in the negative corona discharge area. At least a first stage wetting spraying device is arranged in the removal tower at the upper portion of the smoke inlet end, the wet type electric precipitator is arranged in the removal tower above the wetting spraying device, and a smoke outlet is arranged at the top of the removal tower. The device for removing the PM2.5 in the smoke has the advantages of being capable of removing fine dust of the PM2.5 in fire coal and fine particles of acid mist, heavy metal particles and the like in the smoke. In addition, the removal rate of the PM2.5 is greater than or equal to 95%.
