Title: DRY ICE BALL FOR CLEANING MARINE OIL CONTAMINATION
Abstract:
A dry ice ball (7) for cleaning marine oil contamination. A dry ice marine oil contamination cleaning apparatus comprises a dry ice device (2). The dry ice device (2) comprises a dry ice ball (7) for cleaning marine oil contamination. The dry ice ball (7) for cleaning marine oil contamination consists of a hollow ball body (39). An ice adding port (40) is provided on the ball body (39), a ball cover (41) is arranged at the ice adding port (40), and the ball cover (41) is connected to the ice adding port (40) in a sealed manner. Dry ice (9) is provided in a mold cavity (8) of the ball body (39). A one-way valve (49) is disposed on the ball cover (41), a conducting direction of the one-way valve (49) points to the outside of the ball body (39) from the inside of the ball body (39), and the one-way valve (49) is not conductive in an opposite direction. When the dry ice ball (7) for cleaning marine oil contamination is in contact with oil slick (11) during use, the oil slick (11) transmits, through the ball body (39), heat to the dry ice (9) in the dry ice ball (7) for cleaning marine oil contamination, the dry ice (9) is sublimated to carbon dioxide after absorbing the heat, and the carbon dioxide is discharged out of the ball body (39) through the one-way valve (49) from the interior of the ball body (39). The oil slick (11) is congealed and absorbed by using the dry ice ball (7) for cleaning marine oil contamination, and the oil slick (11) absorbed by the dry ice ball (7) for cleaning marine oil contamination is removed by using a heating device (3) and is gathered in an oil collection tank (35), thereby achieving the purpose of cleaning up the oil slick (11) of the ocean or river in a circulating way.
