The document records that "a wet dust collector with a box design has a pipe designed inside the air inlet, through which the waste gas enters the dust removal liquid for the first dust removal and purification. Then, when the waste gas is discharged upward, it passes through the nozzle structure for secondary dust removal to reduce the dust content in the waste gas." However, the existing technology has an uncertain flow path for the upper exhaust gas, making it difficult to ensure that the exhaust gas can be fully sprayed by the nozzle. Utility Model Content
