Based on the electron transfer in flowing water film and ion directional migration in electrical field

the size distributions and dust layer morphology of collected particles on wet fabrics collector were studied and compared with the collected particles on dry metal collector. To study the deposition and exfoliation characteristics of collected particles on wet fabrics collector

a test bench was built. Besides

the key factors on the deposition and exfoliation process of collected particles on wet fabrics collector were also investigated. The results showed that the collected particles on wet fabrics collector (6.900 μm) were smaller than the dry metal one (9.018 μm) at same position (sample point 15). Wet fabrics collector exhibited a higher collection efficiency. Different from the collected particles on the dry metal electrode

the dust layer pattern on wet fabrics had no relation to the discharge current distribution. Charged particles preferentially deposited on the convex spots and became the depositional centre on the fabrics collector. Eventually

the aggregated particles formed a point or pod like packing structures. The electrostatic force between wet fabrics electrode and dust layer was decreased while the bond force between collected particles increased by the flowing water over fabric collector. Drag force

liquid bridge force

electrostatic force and dust layer gravity were the key factors on the exfoliation process of collected particles on wet fabrics collector.
