Description
Den foreliggende oppfinnelse vedrører en fremgangsmåte for oppsamling av olje fra en forurenset vannoverflate samt en oljeoppsamler for gjennomføring av fremgangsmåten av den type som henholdsvis er angitt i innledningen til det/de etterfølgende apparatkrav. The present invention relates to a method for collecting oil from a polluted water surface as well as an oil collector for carrying out the method of the type respectively stated in the introduction to the subsequent device claim(s).
Ved kjente fremgangsmåter for oppsamling av oljeBy known methods for collecting oil
fra en forurenset vannoverflate benyttes blant annet roterende skovlhjul som delvis neddykket i vannet føres langsmed vannflaten og under rotasjon samler opp olje/vann på skovleflåtene som når de beveger seg fra vannet og opp gjennom vannoverflaten, tar med seg olje/vann som via åpninger ved skovlenes basisparti renner inn i et samlerør eller beholder i skovle-hjulets sentrale parti. Nevnte samlerør eller beholder er oppad åpent slik at nevnte olje/vann renner inn i dette gjennom nevnte åpninger ved skovlenes basisparti idet skovlene heves opp over vannoverflaten og oljen/vannet derved renner mot nevnte åpninger og gjennom disse.(Se f.eks. norsk patent nr. 127.932-fig. ^). Ved nevnte fremgangsmåte søker en å from a contaminated water surface, among other things, rotating paddle wheels are used which, partially submerged in the water, are guided along the water surface and, during rotation, collect oil/water on the paddle floats, which, when they move from the water and up through the water surface, take oil/water with them, which via openings at the paddles base part flows into a collecting pipe or container in the central part of the paddle wheel. Said collection pipe or container is open upwards so that said oil/water flows into it through said openings at the base part of the vanes as the vanes are raised above the water surface and the oil/water thereby flows towards said openings and through them. (See e.g. Norwegian patent No. 127,932-fig. ^). In the aforementioned procedure, one seeks to
skille ut vannet fra det i hver skovle oppsamlede olje/vann ved åpninger i skovlekammernes sidevegger slik at vannet fortrinnsvis skal ha rent vekk under oljen før oljen tømmes inn i nevnte oppsamlingsrør/kammer. I urolig sjø vil bølgene dog ha en tendens til å slå opp over skovlene og forstyrre nevnte skilling av olje og vann slik at en mengde vann også renner inn i oppsamlingsrøret slik at en relativ stor mengde olje/ separate the water from the oil/water collected in each bucket at openings in the side walls of the bucket chambers so that the water should preferably clear away from under the oil before the oil is emptied into said collection pipe/chamber. In rough seas, however, the waves will tend to break up over the vanes and disturb the aforementioned separation of oil and water so that a quantity of water also flows into the collection pipe so that a relatively large quantity of oil/
vann må skilles i i og for seg kjente separeringskammere. water must be separated in separation chambers known per se.
Hensikten med den foreliggende oppfinnelse er å til-veiebringe en fremgangsmåte hvor det under oljeoppsamlingen følger med mindre vann slik at behovet til olje/vann-separerings- utstyr nedsettes, samt at det også tilveiebringes en oljeoppsamler hvor oljeoppsamlingsoperasjonen i liten grad påvirkes av opprørt sjø. The purpose of the present invention is to provide a method where less water is added during oil collection so that the need for oil/water separation equipment is reduced, and that an oil collector is also provided where the oil collection operation is to a small extent affected by rough seas.
Ovennevnte er oppnådd ved hjelp " av de trekk som er angitt i karakteristikken til det etterfølgende fremgangsmåte-krav samt apparatkrav. The above has been achieved by means of the features specified in the characteristics of the following method claim and apparatus claim.
Det er herved tilveiebragt en robust, enkel oljeoppsamler som kan monteres på i og for seg kjent måte foran på A robust, simple oil collector is hereby provided which can be mounted in a known manner at the front of
et fartøy som fører oljeoppsamleren gjennom sjøen, eller en rekke oljeoppsamlere kan koples sammen side ved side slik at det dannes en oljelense, eventuelt en del av en oljelense hvorved oljeoppsamlerne når lensen trekkes gjennom vannet eller vannet strømmer mot oljelensen på grunn av vær og vind, samler opp olje fra vannoverflaten. a vessel that carries the oil collector through the sea, or a number of oil collectors can be connected side by side so that an oil bilge is formed, possibly part of an oil bilge whereby the oil collectors when the bilge is pulled through the water or the water flows towards the oil bilge due to weather and wind, collects oil from the water surface.
To utførelsesformer av oljeoppsamler for gjennomføring av fremgangsmåten vil bli omtalt i- det etterfølgende med hen-visning til tegningen hver Two embodiments of the oil collector for carrying out the method will be discussed in the following with reference to the drawing each
fig. 1 viser oljeoppsamleren i form av et skovlhjul - i snitt - under operasjon i sjøen, og fig. 1 shows the oil collector in the form of a paddle wheel - in section - during operation in the sea, and
fig. 2 oljeoppsamleren i form av et skovlbelte- som løper over to ruller, under operasjon i sjøen. fig. 2 the oil collector in the form of a paddle belt - which runs over two rollers, during operation in the sea.
Fig. 1 viser oljeoppsamlerens skovlhjul 1 i snitt idet eventuell opplagringsramme og eventuelle drivinnretninger for rotasjon av skovlhjulet 1, er utelatt. Fig. 1 shows the oil collector's paddle wheel 1 in section, with any storage frame and any drive devices for rotation of the paddle wheel 1 omitted.
Skovlhjulet 1 omfatter i det viste tilfellet åtte radielle skovler 2 med tiltagende tykkelse fra skovlspiss til skovlbasis idet to og to skovler sammen med sidevegger 3 danner skovlkammere ^ med åpninger 5 ved skovlkammerets bunn. Nevnte skovlkammeråpninger 5 som begrenses av skovlenes basis-partier som samtidig danner et nav 6 med sentral åpning i hvilken det i tettende anlegg mot navveggen er plassert et eventuelt som aksel, rør 7 med en spalteformet åpning 8 eller flere etter hverandre i rørets lengderetning anordnede åpninger i rørets 7 lavere omkretsparti, fortrinnsvis rett bak et vertikalplan gjennom skovlhjulets rotasjonsakse sett i skovlhjulets rotasjonsretning hvilket roterer med oljeoppsamlerens relative fremdriftsretning i vannet. Åpningens 8 tverrdimen-sjon er av samme størrelsesorden som åpningenes 5 tverrmål i skovlhjulets 1 rotasjonsretning. Røret 7 er tilkoplet en suge pumpe (ikke vist) for oppsuging av olje/vann fra røret 7 og skovlkammerne 4 via åpningen 8 i røret 7 og åpningene 5 i skovlkammerne 4, hvilke åpninger 8 og 5 bringes i flukt med hverandre under skovlhjulets 1 rotasjon i sin neddykkede til-stand i sjøen. Rotasjon, av skovlhjulet 1 kan henholdsvis frembringes av den relative bevegelse mellom sjøen og skovlhjulet eller ved hjelp av separat drift (ikke vist) av skovlhjulet. Det kan eventuelt anordnes åpninger (ikke vist) i skovlhjulets 1 sidevegger 3 for utslipping av vann som kan følge med i skovlkammerne k når disse under skovlhjulets 1 rotasjon hever seg. opp over vannflaten 9. In the case shown, the paddle wheel 1 comprises eight radial paddles 2 of increasing thickness from the tip of the paddle to the base of the paddle, two and two paddles together with side walls 3 forming paddle chambers ^ with openings 5 at the bottom of the paddle chamber. Mentioned blade chamber openings 5 which are limited by the base parts of the blades which at the same time form a hub 6 with a central opening in which, in sealing contact with the hub wall, a tube 7 with a slot-shaped opening 8 or several openings arranged one after the other in the longitudinal direction of the tube is placed in sealing contact with the hub wall in the lower circumferential part of the tube 7, preferably directly behind a vertical plane through the axis of rotation of the paddle wheel seen in the direction of rotation of the paddle wheel which rotates with the oil collector's relative direction of travel in the water. The transverse dimension of the opening 8 is of the same order of magnitude as the transverse dimension of the openings 5 in the direction of rotation of the impeller 1. The pipe 7 is connected to a suction pump (not shown) for suction of oil/water from the pipe 7 and the paddle chambers 4 via the opening 8 in the pipe 7 and the openings 5 in the paddle chambers 4, which openings 8 and 5 are brought into alignment with each other during the rotation of the paddle wheel 1 in its submerged state in the sea. Rotation of the paddle wheel 1 can respectively be produced by the relative movement between the sea and the paddle wheel or by means of separate operation (not shown) of the paddle wheel. If necessary, openings (not shown) can be arranged in the side walls 3 of the paddle wheel 1 for the discharge of water which can follow into the paddle chambers k when these rise during the rotation of the paddle wheel 1. up above the water surface 9.
Ved operasjon av oljeoppsamleren har denne en fremdriftsretning relativt vannoverflaten som vist med pilen 10 During operation of the oil collector, this has a direction of travel relative to the water surface as shown by arrow 10
i fig. 1 og skovlhjulet 1 roterer i fremdriftsretningen som vist med pilen 11. Skovlhjulet 1 ligger delvis neddykket slik at minst det nedre omkretsparti av' ncivet 6 befinner seg under vannoverflaten. in fig. 1 and the paddle wheel 1 rotates in the forward direction as shown by arrow 11. The paddle wheel 1 is partially submerged so that at least the lower peripheral part of the 'ncive 6 is below the water surface.
Når skovlhjulet 1 roterer, vil hver skovl 2 når den beveger seg ned mot vannoverflaten, ta med seg et parti av vannoverflaten 9 med olje 9' ned under vannoverflaten. Oljelaget som blir presset ned i vannet blir liggende an mot skovlens 2 underflate som vist ved 2' og vil ettersom skovlen beveger seg videre ned i sjøen, flyte opp langs skovlflaten mot åpningen 5 i skovlkammerets *l bunn som vist ved 2" hvorved det tynne oljelag 9'blir samlet til et vesentlig tykkere lag 9". Idet åpningen 5 kommer i flukt med åpningen 8 i røret 73suges det tykkere oljelag 9" inn i røret 7 ved hjelp av nevnte sugepumpe og frem til den nevnte, ikke viste samlebeholder. Idet skovlhjulet 1 roterer, lukkes atter åpningen 5 i det omtalte skovlkammer etter at oljen er sugd inn i røret 7 When the vane wheel 1 rotates, each vane 2, when it moves down towards the water surface, will take with it a part of the water surface 9 with oil 9' down below the water surface. The oil layer that is pushed down into the water rests against the lower surface of the blade 2 as shown at 2' and will, as the blade moves further down into the sea, float up along the blade surface towards the opening 5 in the bottom of the blade chamber *1 as shown at 2", whereby the thin oil layer 9' is collected into a significantly thicker layer 9". As the opening 5 aligns with the opening 8 in the pipe 73, the thicker layer of oil 9" is sucked into the pipe 7 by means of the aforementioned suction pump and up to the aforementioned collection container, not shown. As the vane wheel 1 rotates, the opening 5 in the mentioned vane chamber is closed again after that the oil has been sucked into the pipe 7
og skovlene 2 med mellomliggende skovlkammere 4 roterer opp av sjøen og frem til ny utgangsstilling hvoretter arbeidssyklusen gj ent as . and the vanes 2 with intermediate vane chambers 4 rotate up out of the sea and up to a new starting position, after which the work cycle is repeated.
Ved å avpasse skovlhjulets 1 rotasjonshastighet og sugepumpens sugekapasitet i forhold til den oppsugde olje/vann-blanding, kan oljeoppsamleren reguleres slik at det følger med svært lite vann for hver oppsuging av oljelaget 9' fra hvert skovlkammer 4. Regulering av rotasjonshastigheten kan når skovlhjulet 1 drives av en drivinnretning, reguleres direkte av operatøren. Hvis skovlhjulet dreies ved hjelp av dens frem-drift i sjøen, kan rotasjonshastigheten eventuelt reguleres ved å endre fremdriftshastigheten samtidig som sjugepumpens sugekapasitet reguleres. Eventuelt kan reguleringen skje ved kun å regulere sugepumpen idet en holder jevn fremdrifts-hastighet og dermed rotasjon av skovlhjulet 1. By adjusting the rotation speed of the vane wheel 1 and the suction capacity of the suction pump in relation to the sucked up oil/water mixture, the oil collector can be regulated so that very little water is included for each suction of the oil layer 9' from each vane chamber 4. Regulation of the rotation speed can when the vane wheel 1 operated by a drive device, regulated directly by the operator. If the impeller is turned by means of its propulsion in the sea, the rotation speed can possibly be regulated by changing the propulsion speed at the same time as the suction capacity of the suction pump is regulated. Alternatively, the regulation can be done by only regulating the suction pump while maintaining a constant forward speed and thus rotation of the impeller 1.
Flere oljeoppsamlere av den i fig. 1 viste type kan som tidligere nevnt koples ved siden av hverandre idet røret 7 enten koples til røret 7 i en hosliggende oljeoppsamler eller røret 7 kan være et gjennomløpende rør som danner aksel for et flertall skovlhjul. Ved rørets ene ende, eventuelt begge ender, er det da tilkoplet sugepumpe. Several oil collectors of the one in fig. 1 shown type can, as previously mentioned, be connected next to each other, the pipe 7 being either connected to the pipe 7 in an adjacent oil collector or the pipe 7 can be a continuous pipe which forms an axle for a plurality of paddle wheels. At one end of the pipe, possibly both ends, a suction pump is then connected.
Ved en annen utførelsesform av oljeoppsamleren er skovlene 12 anbragt på et belte 13 som løper over to ruller 14, 15. 'Ved skovlbeltets bakre parti regnet i dettes fremdriftsretning som vist med pilen 15, er-det plassert et oljeoppsam-lingsrør eller kammer.16 som er tilsluttet en ikke vist sugepumpe .• In another embodiment of the oil collector, the vanes 12 are placed on a belt 13 which runs over two rollers 14, 15. At the rear part of the vane belt, counted in its direction of travel as shown by arrow 15, an oil collection tube or chamber is placed. 16 which is connected to a suction pump not shown.•
Under operasjon virker skovlbeltet på samme måte som omtalt i forbindelse med skovlhjulet 1, men fordi skovlene 12 med mellomliggende skovlkammere 17 holdes neddykket i en vesentlig lengre tid enn skovlkammerne 4 i forbindelse med skovlhjulet 1, vil oljen få lengre tid til å flyte opp og samle seg i skovlkammernes bunnparti før oljen suges inn i oppsam-lingsrøret eller kammeret 16 via åpninger ved skovlkammernes bunn og åpning i oppsamlingsrøret 18 resp. 19. De to utfør-elsesformer av oljeoppsamleren ifølge oppfinnelsen, nemlig med henholdsvis skovlhjul og skovlbelte kan bygges opp i bære-rammer slik at det dannes enheter som enten festes ved hjelp av kjente undersøtttelsesanordninger til fartøyer for oppsamling av olje fra vannoverflaten eller som kan koples sammen til lenser slik som tidligere omtalt. Når et flertall oljeoppsamlere koples sammen til en oljeoppsamlingslense, kan det være aktuelt å anordne flytelegemer med passende mellomrom på lensen eller i direkte tilknytning til hver oljeoppsamler for å holde disse i passende neddykket stilling i sjøen. During operation, the vane belt works in the same way as described in connection with the vane wheel 1, but because the vanes 12 with intermediate vane chambers 17 are kept submerged for a significantly longer time than the vane chambers 4 in connection with the vane wheel 1, the oil will have a longer time to float up and collect itself in the bottom part of the paddle chambers before the oil is sucked into the collection pipe or chamber 16 via openings at the bottom of the paddle chambers and opening in the collection pipe 18 or 19. The two embodiments of the oil collector according to the invention, namely with paddle wheel and paddle belt respectively, can be built up in support frames so that units are formed which are either attached by means of known anchoring devices to vessels for collecting oil from the water surface or which can be connected together into lenses as previously discussed. When a plurality of oil collectors are connected together to an oil collection bilge, it may be relevant to arrange floating bodies with suitable intervals on the bilge or in direct connection to each oil collector to keep them in a suitable submerged position in the sea.
