Abstract
The invention relates to a method for manufacturing a fence/ice grid (6) on site by using ice, restraining polluted oil floating on the sea surface to prevent the oil from spreading and facilitate the recovery of the oil, which comprises the following steps: cooling gas (frozen, preferably liquid gas, including frozen air) is continuously discharged from nozzles at a predetermined depth/position (8) below the sea surface, and a cooling gas discharge vessel (7) is driven along a path surrounding the contamination source/contaminated area (5). During the rising of the cooling gas from its discharge depth/position, it will more or less release its own cold capacity to the adjacent sea water, freezing this part of the sea water to build up said ice railing/ice grid (6).
Description
The present invention relates to a kind of containment of floating contaminated oil across the sea or the operational method of similar contaminant, this method is to adopt floating fence/boom to surround the sea that oil film or floating nothing control oil film source/pollution sources or seabed release the source whole or in part to spray thing, with the diffusion that stops oil/pollutant be convenient to its withdrawal.
For this purpose, can adopt the traditional hurdle oil fence system of a lot of patterns.But shortcomings such as existing oil boom system has limitation, is not durable, easily loss, omission.
Surround the sea in big zone, just need one and have the hurdle oil fence that encloses journey quite greatly.But this hurdle oil fence at first needs the platform place, and secondly its setting and operation are all very inconvenient.Known hurdle oil fence is to connect by several short hurdle oil fences or by the section of many fence or pitch chain to form, and this link is very time-consuming, and its point of contact often becomes the weak spot of formed hurdle oil fence.
Known hurdle oil fence has than slight drag, therefore, under the effect of wind, bad weather, ripples, wave and surperficial current, moves quickly easily and departs from the set-point and/or change line circle of hurdle oil fence.This move and/or the change of hurdle oil fence line circle can cause the hurdle oil fence to lose efficacy, the hurdle oil fence that thing is sprayed on the sea that can cause surrounding draining source, seabed especially lost efficacy.
The operational method that the purpose of this invention is to provide a kind of the above-mentioned type, this method have been eliminated many shortcomings of known floating fence/boom, and other shortcomings that are not eliminated have also been alleviated at least widely.
The object of the invention can realize by the method with feature described in claims.
The top priority of the inventive method is to adopt a kind of ice hurdle to surround to let out oil spill, " the hurdle oil fence " that so-called ice hurdle is made up of the sea-water ice that forms on the spot.Another task is the denseness that changes contaminated oil, thereby is convenient to from the sea it be reclaimed.
Realizing the plain mode of the inventive method, is from certain position/degree of depth below the sea, and discharging is called the gas that is in the suitable state of cooling of " refrigerating gas ".For example, this suitable refrigerating gas can be a liquid nitrogen.In general, any gas that comprises air can be used.Adopted gas will be cooled to low like this temperature: bubble from the said degree of depth/position to the process of sea level rise, can make enough around the seawater glaciation.The discharge method of this refrigerating gas is: the gas that gives off from the said degree of depth/position is led to the distance on sea at it, and the seawater around self cold capacity is delivered to makes the glaciation thereupon of this part seawater.This refrigerating gas will discharge successively, all or basically surrounds pollutant up to the ice hurdle/ice foot that is frozen into.
In addition, the discharging of refrigerating gas is measured, so that form open-textured ice, loose ice can float De Genggao, and its fragility is littler than solid ice.
In all cases, the refrigerating gas discharge value on the temperature of refrigerating gas (with cold capacity), unit sea and the discharge depth of refrigerating gas all must be regulated according to the weather conditions in this waters.Importantly, the thawing time that determine this artificial ice hurdle is for how long.In the All Time before other gage work (for example recovery of pollutant) is done, must guarantee to ice the complete of hurdle.The cross sectional dimensions and the pollutant scope on ice hurdle adapt.
The characteristic on ice hurdle can be by regulating refrigerating gas the discharge value on temperature, discharge depth, unit interval and unit sea control.
Freeze into some nets in ice hurdle/ice foot, for example this ice hurdle/ice foot can be reinforced or strengthen to nylon rope.Must consider that local weather conditions are processed into suitable size with such net.In addition, if without the mesh reinforcement thing, also can add chemical substance to strengthen the soundness of ice.
If desired one lasting during in keep the complete of ice hurdle/ice foot, can be after ice hurdle/ice foot freezes, provide refrigerating gas to ice hurdle/ice foot discontinuously or continuously in during required.
If necessary, refrigerating gas can also be used to lowering the viscosity of oil slick.
According to operational method of the present invention, owing to can make the ice hurdle/ice foot of any scale at any time on the spot, thereby can make than with the more various types of traditional hurdle oil fence system.This ice hurdle or ice foot can be made has the cross sectional dimensions that adapts with contamination accident, and the ice foot that is frozen into does not have special weak spot.
The exemplary embodiments of roughly having represented operating type of the present invention in the accompanying drawings.
Fig. 1 is the lateral view in a place of expression.Wherein, it is besieged not have control draining source, to stop Pollutants Diffusion.
Fig. 2 is the vertical view in place shown in Figure 1.
Among the figure, mark 1 and 2 is represented sea and seabed respectively.
The nothing control draining source among Fig. 1 of being illustrated in be one on the sea leakage of oil ship 3 and the seabed below the seabed leakage point 4 of oil storage tank (not shown).Seabed oil pollution source 4 also can comprise the oil tank or the undersea device at a bottom, and the sea of pollution sources 4 is sprayed thing and represented that with oil slick 5 in Fig. 2, it is besieged.
In order to surround oily overflow area 5 with a suitable fence/ice foot, refrigerating gas 9 emits through hose/tube line 8 from an emergent ship 7, the nozzle 8 of hose/tube line ' be positioned at 1 following desired depth place, sea.In the process of sea level rise, discharge self cold capacity, this part seawater so glaciation 6 at refrigerating gas to contiguous seawater.When the figure P direction of arrow moved, the discharging of this undersea refrigerating gas was constantly being carried out at ship 7, and 5 is besieged up to oily overflow area.
