Description

A METHOD AND AN APPARATUS FOR COLLECTING OIL FROM A SURFACE OF WATER
FIELD OF THE INVENTION
The present invention relates to a method of collecting oil, and particularly to a method for collecting oil from a surface of water. The present invention further concerns an apparatus for collecting oil from a surface of water.
BACKGROUND OF THE INVENTION
Document WO 2007/059606 A1 discloses a skimmer used to remove both heavy and light oil from a body of water or for the removal of either light or heavy oil and a method of operation of the skimmer. The heavier oil is removed from a first location on a rotating member and the lighter oil is removed from a second location on the rotating member. The oil removed at both locations is collected at a single location and a pump removes the oil from the skimmer. A problem with the known skimmer is that excess water that is mixed with the removed oil is transferred with the oil via a brush wheel to a container for the removed oil when using the skimmer. This requires more storage space for the removed oil.
BRIEF DESCRIPTION OF THE INVENTION
An object of the present invention is to provide a method and an apparatus for implementing the method so as to overcome the above problems.
The objects of the invention are achieved by a method and an arrangement, which are characterized by what is stated in the independent claims. The preferred embodiments of the invention are disclosed in the dependent claims.
The invention is based on the idea of leading the oil collected from a surface of water to a converging space and a gap for increasing the speed of the collected oil. This causes water to separate from the oil and flow back to the body of water.
An advantage of the method and arrangement of the invention is that less storage space for the collected oil is needed and thus more oil can be collected before the collected oil storage has to be emptied.
BRIEF DESCRIPTION OF THE DRAWINGS
In the following the invention will be described in greater detail by means of preferred embodiments with reference to the accompanying drawings, in which
Figure 1 is a schematic drawing of the apparatus according to an embodiment of the invention;
Figure 2 is a schematic drawing of a scraper comb used in the apparatus. DETAILED DESCRIPTION OF THE INVENTION
The invention relates to a method for collecting oil from a surface 1 of water. The method comprises the steps of - collecting oil from a surface 1 of water to bristles 2 of a rotating brush wheel 3, - scraping oil from the bristles 2 of the rotating brush wheel 3 using a scraper comb 4, - leading scraped oil to a space 5 formed between the scraper comb 4 and a wall 6, the space 5 having a converging shape, - leading oil along the converging space 5 to a gap 7, - leading oil through the gap 7, and - leading oil from the gap 7 to a container 8.
By surface of water is meant a surface of a body of water, for example a lake or a sea.
The rotating brush 3 is preferably connected to a marine vessel. During collecting oil the marine vessel can be stationary or in motion.
The scraped oil is packed to the converging space 5 and through the gap 7 by the pressure caused by rotating brush wheel 3 feeding more oil to the space 5. The converging space 5 causes the oil to increase speed when travelling through the space 5. This causes water to separate from the oil. Separated water then runs back to the body of water. Preferably the surface of the brush wheel 3 at the stem of the bristles 2 comprises tangential grooves for improving the flow of the separated water. Separated water flows along the grooves back to the body of water.
According to an embodiment the gap 7 is formed by the scraper comb 4 and the wall 6 and being situated at the end of convergence of the space 5.
According to an embodiment the scraper comb 4 has at least partially curved shape for directing oil received from the gap 7 towards the container 8.
According to an embodiment of the invention the width of the gap 7 is adjusted. Adjusting the width of the gap 7 allows collecting different kinds of oils using the same brush wheel 3 without the need for changing the brush wheel 3 according to the type of the oil collected.
According to an embodiment the width of the gap 7 is adjusted during collecting oil. Adjusting the gap 7 during collecting oil allows collecting oil in situations where several different types of oil have been spilled.
According to an embodiment the width of the gap 7 is adjusted by moving the scraper comb 4 and/or the wall 6. Preferably the width of the gap 7 is adjusted by moving the scraper comb 4 in relation to the wall 6. It is also possible to have a movable, deformable or flexible wall and adjust the gap 7 by moving the wall 6 in relation to the scraper comb 4.
According to an embodiment the gap 7 is having a width of between 1 to 15 mm. The width of the gap 7 depends on the oil collected. Light oils, such as diesel oil, require narrow gap 7. Heavy oils require wide gap 7. If the gap is too narrow, the collecting efficiency is reduced. If the gap is too wide, excess water is collected with the oil to the container. An operator of the skimming equipment is able to determine the optimal gap width for the current situation based on a visual observation of the flow of the collected oil from the gap 7 to the container 8. It is also possible to adjust the gap 7 before collecting oil based on information of the oil type obtained beforehand.
Oil collected to the brush wheel 3 can be scraped off the brush wheel 3 on any position that is above the surface 1 of the water. Preferably the collected oil is scraped off after the brush bristles 2 rise from the surface 1 of the water, but before it reaches the topmost position of the brush wheel 3. According to an embodiment of the invention, oil is scraped from the brush wheel 3 in a position less than 180 ° from the lowest position of the brush wheel 3 in the direction of rotation of the brush wheel 3. This improves the flow of the water sepa- rated from the oil back to the body of water as it can flow downwards away from the converging space.
According to an embodiment the wall 6 is a part of a wall of the container 8 or a part of a sluice directing oil from the gap 7 to the container 8.
The invention also relates to an apparatus for collecting oil from a surface of water, comprising - a rotatable brush wheel 3 for collecting oil from a surface 1 of water on the bristles 2 of the rotatable brush wheel 3, - a scraper comb 4 adapted to scrape oil from the bristles 2 of the brush wheel 3, - a container 8 for containing collected oil, - a leading means for leading scraped oil from the scraper comb 4 to the container 8, - a space 5 having a converging shape formed between the scraper comb 4 and a wall 6, the space 5 being adapted to receive oil from the scraper comb 4, and - a gap 7 in fluid connection with the space 5 adapted to receive oil from the space 5 and to lead oil through the gap 7 towards the container 8.
According to an embodiment of the invention the gap 7 is formed by the scraper comb 4 and the wall 6 and it is situated at the end of convergence of the space 5.
According to an embodiment the apparatus comprises adjusting means 9 for adjusting the gap 7. According to an embodiment the adjusting means 9 for adjusting the gap 7 is adapted to adjust the width of the gap 7 by moving the scraper comb 4 and/or the wall 6.
According to an embodiment the width of the gap 7 is between 1 to 15 mm.
According to an embodiment of the invention the apparatus comprises adjusting means 10 for adjusting the space 5. According to an embodiment the adjusting means 10 for adjusting the space 5 is adapted to adjust the angle of convergence of the space 5. For example the adjusting means 10 for adjusting the space 5 is adapted to tilt the scraper comb 4 in relation to the wall 6.
According to an embodiment the adjusting means 9 for adjusting the gap 7 and/or the adjusting means 10 for adjusting the space 5 is/are adapted to adjust the distance between the scraper comb 4 and the brush wheel 3.
Preferably the adjusting means 9 for adjusting the gap 7 are such that an operator of the apparatus can adjust the gap 7 while using the apparatus. There are numerous ways how to implement the adjusting means 9 for adjusting the gap 7 and the adjusting means 10 for adjusting the space. A skilled person can easily figure out, how to implement these means.
According to an embodiment if the invention the scraper comb 4 is adapted to scrape oil from the bush wheel 3 in a position less than 180 ° from the lowest position of the brush wheel 3 in the direction of rotation of the brush wheel 3.
According to an embodiment the wall 6 is a part of a wall of the container 8 or a part of a sluice directing oil from the gap 7 to the container 8.
According to an embodiment the wall 6 is curved or straight.
The invention also relates to an use of the method or the apparatus of the invention for collecting oil, wherein the gap 7 is adjusted according the viscosity of the oil.
