① Dust Removal Efficiency: The efficiency of a wet dust collector is a crucial performance indicator for selection. The specific dust pollutants in a certain state of gas flow directly affect the collection efficiency.

②Operational Flexibility: For any operational equipment, consider its load capacity and how it affects collection efficiency when the airflow exceeds or falls below the design value. Similarly, be prepared for operation when dust concentration is unstable or continuously higher than the design value.

③ Hydrophobicity: Wet scrubbers are not highly efficient in purifying hydrophobic dust, and are generally not suitable for operations where design values dictate specific procedures.

④ Adhesiveness: Wet scrubbers can purify adhesive dust, but rinsing and cleaning should be considered to prevent clogging.

⑤ Corrosiveness: When purifying corrosive gases, anti-corrosion measures should be considered.

⑥ Water Consumption: Amount of water used by dust collectors, wastewater treatment discharge, and winter anti-freezing measures for water.

Sludge Treatment: Sludge treatment is an inevitable issue with wet scrubbers, and efforts should be made to minimize the extent of pollution hazards.

Operation and Maintenance: Generally, it should be avoided to have moving or rotating parts inside the dust collector. Pay attention that the gas flow through the cross-sectional area of the channel may cause blockage when it is too small.
