Abstract
The invention discloses a method of cleaning greasy dirt. The method of cleaning the greasy dirt is characterized in that a drag boat of a dragnet carried by the drag boat are used for cleaning sea surface greasy dirt, and a tanker is configured as an auxiliary facility. N air bags are arranged on the periphery of the dragnet carried by the drag boat. A filtering net of the dragnet is made of oleophobicity nanometer material in which water can penetrate but oil cannot penetrate. When the dragnet carried by the drag boat sails towards a greasy dirt sea surface, in the sailing process, the dragnet is frapped and the air bags of the dragnet are not inflated; when the drag boat reaches near the greasy dirt sea surface and the dragnet is arranged below the greasy dirt sea surface, the drag boat inflates the air bags of the dragnet by an air compressor through a rubber tube till the dragnet emerges from the water, the dragnet fully carried by the greasy dirt is dragged near the tanker, the tanker pumps the greasy dirt in the dragnet into an oil can of the tanker through an oil pump which is configured on the tanker.
Description
Technical field
The present invention relates to a kind of method of clearing up greasy dirt.
Background technology
At present, a lot of offshore oil pollution accidents all can occur in the world every year, Oil Spills or topple can cause fearful ecocatastrophe.In Atlantic Ocean accident, thousands of ton greasy dirts swim in the sea as Spain's oil tankers " prestige " of 2003 number, and fish, seabird and marine animal and plant are all afflicted with great suffering torment.And the cleaning oil pollution at sea is a job of wasting time and energy, and the greasy dirt that the oil tanker accident is left over will just can be cleaned out by good some months.
The sea oil spill sweep-out method mainly comprises: natural facture, contain with reclaim, marine firing method, oil-spill dispersant, the decantation and biological restoring method.These methods have some defectives, or inefficiency, or with high costs.The design of " oil pollution at sea collecting ship " has been proposed recently as the high pellet of marine architect Christian of French Alstom oceanographic equipment company, calculated " oil pollution at sea collecting ship " long 136 meters, wide 32 meters, be a trimaran.The purpose of design engineer is, make ship can be as early as possible, take measures after the oil tanker accident with using up, avoid the gross pollution consequence, trimaran is comprised of a central hull and two side hulls, total has advantages of that stable, the anti-horizontal and vertical ability of shaking of direction is strong, in the situation that support can be in the off-lying sea operation, seven grades of waves also can go to sea.Two each 8 meters wide water channels are arranged between hull, guarantee that the disturbance on water channel is not strong especially.Central authorities' hull can be stored at most 6 kiloton greasy dirts, is equivalent to the collecting amount of a day, and each week, this ship can be collected 20,000 tons of sea surface oil stains.Its cost is very high, estimates that the cost of every ship may be up to 100,000,000 Euros
Summary of the invention
The present invention is exactly the shortcoming for present offshore spilled oil sweep-out method, has proposed a simple method efficient and with low cost.It comprises the trawlnet of collecting sea surface oil stain, and to see through the seawater molecule, the oil molecule can't see through the mesh of filter screen only; The arrangement of the peripheral intervals of filter screen several air bags.When towboat is dragged to the below on greasy dirt sea to filter screen, towboat is by the airbag aeration of the air compressor in ship to filter screen, the air bag emersion sea of inflation, because to see through seawater, the oil slick on sea is collected into filter screen to filter screen, at this time only, the peripheral rope of filter screen is tightened up, near by towboat taking to the oil tanker with oil suction pump, oil tanker be by oil pump, and the oil slick in filter screen is pumped into oil tank in oil tanker.Then, by the brake equipment of towboat, that the air bag of filter screen is emptying, towboat can be recovered to filter screen in hull like this, then moves to the sea of greasy dirt, and the operation above repeating recycles, and also many towboats are worked simultaneously simultaneously, improve cleaning efficiency.Trawlnet of the present invention can have tens to the hundreds of sq m.To process the sea surface oil stain of different sizes.
The present invention compares with the method for present cleaning greasy dirt, has simply, and cost is low, except filter screen can adopt permeable oil proof nanometer oleophobic material, and other can be combined with and realize with prior art.
The specific embodiment
Below the present invention is described in further detail.
after the particular location that determines contaminated greasy dirt sea, the towboat that trawlnet is carried in use navigates by water the greasy dirt sea, in the navigation process, trawlnet is tightened up and the air bag of trawlnet periphery is not inflated, when towboat arrives below, greasy dirt sea to trawlnet, towboat passes through the interior air compressor of ship via the airbag aeration of the sebific duct on towboat to trawlnet, the air bag emersion sea of inflation, because the filter screen of trawlnet is only to see through seawater, the oil slick on sea is collected in filter screen, at this time, the strap of trawlnet is tightened up, to be carried the trawlnet of full sump oil by towboat, check near oil tanker, oil tanker passes through oil pump, sump oil in trawlnet is pumped into oil tank in oil tanker.Then, by the brake equipment of towboat, that the air bag of trawlnet is emptying, towboat can be recovered to trawlnet in hull like this, resails by the sea of greasy dirt, and the operation above repeating recycles, and also many towboats are worked simultaneously simultaneously, improve cleaning efficiency.Trawlnet of the present invention can have tens to the hundreds of sq m.
Claims (6)
1. a method of clearing up greasy dirt, is characterized in that using the trawlnet that towboat and towboat carry to clear up sea surface oil stain, and be equipped with oil tanker as auxiliary facilities.
2. the method for cleaning greasy dirt according to claim 1, is characterized in that on described towboat, air compressor being arranged.
3. the method for cleaning greasy dirt according to claim 1 is characterized in that the trawlnet periphery that described towboat carries settled n air bag.
4. the method for cleaning greasy dirt according to claim 1, is characterized in that the filter screen of the trawlnet that towboat carries is made by permeable oil proof oleophobic nano material.
5. the method for cleaning greasy dirt according to claim 1, during the trawlnet navigation greasy dirt sea that it is characterized in that carrying when towboat, trawlnet is tightened up and the not inflation of air bag of trawlnet; Near towboat arrives at the greasy dirt sea, and when trawlnet was placed in the below on greasy dirt sea, towboat was by the airbag aeration of sebific duct by the air compressor pair trawling, until trawlnet emerges.
6. the method for cleaning greasy dirt according to claim 5 is characterized in that a trawlnet ship towed that carries full sump oil hauls oil tanker claimed in claim 1, and the oil pump of oil tanker by its outfit is pumped into the sump oil in trawlnet in oil tank in oil tanker.
