Wet dust removal device and dust removal method for building engineering construction

The wet dust removal device comprises a bottom plate, a dust removal cylinder and a water inlet cylinder fixedly arranged on the top face of the bottom plate through a supporting plate, a rotating disc is rotationally arranged in the water inlet cylinder, a water inlet groove is formed in the surface of the rotating disc, and a water inlet control mechanism is arranged in the water inlet groove; the invention relates to the technical field of wet dust removal. According to the wet dust removal device for building engineering construction and the dust removal method, through the arrangement of the water inlet control mechanism and the cleaning mechanism, atomization water can be pretreated, impurities or calcium contained in the water can be filtered out, and through the rotary arrangement of the multiple water inlet grooves, the treatment efficiency of water filtering can be improved, and the dust removal effect is improved. And meanwhile, the blocked filter plate can be automatically cleaned synchronously, s
