OIL REMOVAL METHOD AND APPARATUS

摘要

A device for removing spilled oil, oily substances or other liquids from a surface has a main body (2) with a pair of handles (3) towards its upper end and a cleaning head (4) at the lower end. The cleaning head is fitted with rotary brushes (5) and also contains a motor and drive gear. At the upper end of the main body (2) a flexible pipe (6) is connected to a hollow passage formed by and extending through the main body (2) via a short flexible pipe (6') to the cleaning head (4). In the opposite direction the flexible pipe (6) extends to remote air pressure, vacuum and sorbent material sources. The device (1) has three main modes of operation which are used in sequence to clean up spilled oil etc. It is used to supply absorbent material (e.g. chipped bark) to the contaminated ground; then the absorbent material is massaged into the surface of the ground; and finally the absorbent material together with the liquid is removed.
