The water flows through the main pipeline 12 to each branch pipeline 13 and is discharged from each nozzle 14 to spray the energy storage product carried by vehicle. After spraying, the spraying water enters the internal of the circulation pool 2 through the water inlet 25. The water flow undergoes sedimentation of some impurities through the sedimentation tank 21, and then flows into the S-shaped channel, successively passing through the first filter screen 22 and the second filter screen 24 for sedimentation of tiny impurities.
