AI Technical Summary

Technical Problem

Existing oil dispersant spraying devices cause excessive atomization, preventing the oil dispersant from quickly reaching the water surface and potentially altering its properties, thus affecting the spraying effect.

Method used

The system employs an explosion-proof motor and roller pump for priming. The dispersant and water-soluble solvent are drawn into the roller pump through a siphon effect of gas flow. The system creates a low-pressure environment within the roller pump. The system includes an electric spraying device with inlets for both dispersant and water-soluble solvents, a storage tank, a rubber hose and its extension spray assembly, and an adjustable nozzle connected to the spray gun via a rubber hose.

Benefits of technology

This method achieves uniform mixing of the oil dispersant and water, avoids excessive atomization, ensures that the oil dispersant quickly falls onto the water surface, and improves the uniformity and effectiveness of the spraying operation.
