Abstract
An irrigation type oil skimmer and a method for skimming oil are disclosed. The skimmer includes a lower hull (100) capable of floating and submerging, and capable of discharging sea water through an opening while thickening accumulated oil layer. An oil drawing means having shape of a water wheel is installed on the deck of the lower hull (100), for retrieving the oil layer on the sea surface toward a central tank (110) when the lower hull (100) is submerged. A main floater (300) provides a floating force to the deck, and has a guide path (310) partly communicating with the central tank (110). An oil separating/extracting means (400) has a shaft (411) at a level higher than that shaft (211) of the water wheel of the oil drawing means (200), for separating the upper oil layer of the central tank (110) to send the oil through the guide path into an oil collecting tank (600). The method for skimming oils includes the step of moving the oil layer at the sea level along with the sea water toward a central tank having a certain space (first step). At a second step, the sea water is made to sink and the oil to float with help of the floating force, thickening the oil layer. At a third step, only the surface oil is sent to the water wheel to further separate the oils from the residual sea water. Thus when the skimmer moves toward the emergency site of an oil spill, the lower hull is lifted, effectively increasing the skimmer mobilization speed. When the skimmer arrives at the site, it is submerged to recover the oil layer into the skimmer; therefore, facilitating overall oil recovery process. Further, the presence of the main floater makes it possible to carry out an oil recovering operation at all weather conditions.

Herein, blade 220 places radially in the blade case 212 of the rotary drum 210 that axle P1 rotates, and blade 220 is around eccentric shaft 211 rotations.Each rotary drum eccentric shaft holding plate 230 all has the diameter rotation track bigger than the diameter of rotary drum 210, is used to keep eccentric shaft 211, also has a locked groove 231 coaxial with eccentric shaft 211.Holding plate 230 preferably is fixed on the lower hull 100.
Among Fig. 7, the position is 1. corresponding with the solid line of Fig. 6, and the position is 2. corresponding with the dotted line among Fig. 6.
The following describes the working process of skimming plant of the present invention.
As shown in Figures 1 to 3, when skimming plant is transferred to the area of accident, give first to the 3rd float surge tank 111,121 and 131 inflations, make wherein the absolute altitude of water reduce to position L1.Then, lower hull rises to sea absolute altitude S1.In this position, the resistance of water reduces, and skimming plant can walk with common ship equally fast (propelling unit of skimming plant is omitted among the figure).After skimming plant arrived the leakage of oil zone, first to the 3rd unsteady surge tank 111,121 and 131 water-fillings to absolute altitude L2, made lower hull 100 dives to sea absolute altitude S2.The oil that leaks is mixing the seawater Oil sucking device 200 that leads naturally.
In this case, as shown in Figure 1, what resistance seawater does not run into just imports Oil sucking device 200 by Oil Guide wall 510.At this moment, starting Oil sucking device 200 is seawater band oil importing center storage tank 110.Shown in Fig. 6 and 7, by rotary drum 210 from dotted line position (Fig. 7 2.) to solid line position (Fig. 7 1.) Rotate 180 °, can make this importing become possibility.
For example, be installed on the blade 220 of extreme lower position in the blade case 212 of rotary drum 210 (dotted line position " a "), rotate to the uppermost position in fig-ure of rotary drum 210 (solid line position " b ").In this one-period, blade 220 is inserted into leading in the concentric case 231 by it and protruding 221 remains on extended position.Like this, in the position of Fig. 7 1. (Fig. 6 solid line), blade 220 keeps maximums to expose state.So because blade 220 as means of delivery is arranged, oil on absolute altitude S2 and sea water mixing thing are transplanted on the right side by the left side from Fig. 6 continuously, promptly enter central bin 110.
In this case, blade 220 moves and rotary drum is not with the eccentric rotation of extra duty along case 231 with one heart.Thereby be with the like this eccentric rotation of the rotary drum of blade to be repeated, oil is by uninterrupted pumping.Because of there not being extra duty, the driving power of rotary drum 210 can reduce.In the storage tank of center, the seawater of discharging by bottom opening 120 keeps lacking than the oil water mixture of coming in, so that can guarantee that absolute altitude S3 is than former absolute altitude S2 height.If the absolute altitude S3 of case 110 is higher than former absolute altitude S2, then relative water pressure rises, and seawater is discharged by opening 120 serially thus.The result makes the oil reservoir in the case 110 become thicker.
In this case, the size of bottom opening 120 is by the size decision of the rotating speed and the blade 220 of consideration Oil sucking device 200.
Oil separation/extraction element 400 has the structure identical with Oil sucking device 200.But in this device, eccentric shaft 411 is arranged than eccentric shaft 211 height of Oil sucking device 200.And the minimum blade 420 of rotary drum 410 contacts with oil reservoir, thereby blade can be transported to oil in the collector tank 600.In this case, owing to blade 420 moves along curved portions 611, so oil also moves on in first collector tank 610 along curved portions 611.The oil of carrying contains seawater, and these seawater sink owing to proportion is different.The seawater that sinks is led along spaced walls 613 and is back to center storage tank 110, and seawater is discharged through bottom opening 120 therefrom.In first and second collector tanks 610 and 620, be hung with circulation plates 616 and 617, they slow down the mobile of oil and water and water are thoroughly separated from oil.
Because the height t 1 of first collector tank 610 is higher than the absolute altitude S3 of center storage tank 110, higher hydraulic pressure is discharged isolated seawater automatically.Seawater is discharged face (plate) 615 should be the same high with first collector tank 610.Like this, too high if the pasta of first collector tank 610 becomes, oil will advance in second collector tank 620 in overflow.The height t 2 of second collector tank 620 is higher and lower than the height of first collector tank 610 than the height of center storage tank 110.So just formed a hydraulic pressure, seawater is heavy at the bottom of case, discharges by drainage channel 621.Best, drainage channel 621 is the same with the height of center storage tank 110.Like this, because hydraulic pressure, seawater is discharged into center storage tank 110, has avoided from the seawater reverse direction flow of center storage tank 110 to collector tank 600.The oil spill of collecting in second collector tank 620 flows to the 3rd collector tank 630.Oil in last the 3rd collector tank 630 is transported to a petrol storage tank or an oil carrier (not shown) by transport pipe 618.
Described the present invention will be not limited to specific embodiment and figure, and industry those of ordinary skill is all clear, under the condition of defined scope, can add some changes and modification to it in not leaving appended claims of the present invention.
According to described the present invention, provide one and can rise/submersible lower hull, have an Oil sucking device, oil a separations/extraction element, center storage tank and its collector tank that provides that is that continues.And, a main float is provided.When skimming plant was transferred to the leakage of oil waters, lower hull rose, so skimming plant is transferred fast like this.After skimming plant was reached the spot, lower hull pulled the plug, and oil reservoir is recovered to skimming plant.So its transfer and operation all are fast and efficiently.And the oil suction since lower hull pulls the plug is so that carry out operation across the sea, and the energy consumption of drawing water just can be saved.Utilize proportion different water with the oil separation and make the oil reservoir thickening.So oily recovery operation has just accelerated.And, for purifying the oil that reclaims, being provided with a plurality of collector tanks, the result has improved oily purity.In addition, because main float is arranged, the reclaimed oil operation can be carried out under any weather.
