[0002] Wet dust collector is commonly known as "demister". It is a device that brings dust-laden gas into close contact with liquid, and utilizes the inertial collision of water droplets and particles or the full mixing of water and dust and other effects to capture particles or enlarge particles or retain them in a fixed container to achieve the effect of separating water and dust.

[0003] A Chinese patent with publication number CN211462524U discloses a wet dust removal equipment, including a dust removal chamber and a spray device arranged in the dust removal chamber, wherein an air inlet is arranged on one side of the lower part of the dust removal chamber, and an air outlet is arranged on the top thereof; a guide plate is also arranged inside the dust removal chamber, and the horizontal plane where the guide plate is located is higher than the horizontal plane where the air inlet is located; the spray device is arranged above the guide plate, and the spray device includes a water supply pipe and an annular diverter pipe, which is connected to the water supply pipe, and both are arranged horizontally, and a plurality of atomizing nozzles are arranged on the annular diverter pipe, which can atomize water and then spray it out.
