This invention discloses an adaptive sewage discharge method and device for wet dust collection equipment. First, the dust collection efficiency and corresponding turbidity data of the wet dust collection equipment for particles of different sizes are obtained. A nonlinear regression model is used in conjunction with the above data to establish a quantitative relationship model between turbidity and dust collection efficiency for particles of different sizes. Then, a dust collection efficiency threshold is set, and a curve showing the change in dust collection efficiency with liquid turbidity is generated based on the model, thereby determining the turbidity threshold corresponding to each particle size. During dust collection, the particle size of the main particles in the environment is first measured, and then the corresponding model and turbidity threshold are determined. During the dust collection process, the turbidity value of the liquid inside the equipment is continuously monitored until the turbidity threshold is reached, at which point the liquid inside the equipment is discharged and replaced. If dust collection is subsequently carried out in other environments, only the particle size of the particles in the corresponding environment needs to be determined to achieve adaptive sewage discharge for particles of different sizes. This allows the equipment to operate in the optimal range that balances dust collection efficiency and water conservation.
