The cavitation unit (7) will introduce a strong cavitation in the water, the cavitating action destroying any organic tissue and cell membranes of organisms present in the water. In the cavitation unit (7) hydrogen and steam are added to the water, while oxygen is removed. The oxygen-depleted water will exhibit a reduced corrosive effect on the ballast tanks.
Description
Technical field
The present invention relates to Treatment of Ships'Ballast Water with method that reduces biological pollution and the equipment that is used for this method.
Background technology
When boats and ships during a harbour unloaded of cargo, for boats and ships off-load or sub-load that prevent to set out at sea are unsettled, usually at this harbour in ship and vessel the suction seawater.This operation may and cause local marine species (for example bacterium and many cells species) to enter ballast tank usually.When boats and ships arrive its next one to loading and rely on the port, must extract water ballast out.If this water comprises biomaterial alive, may cause biological pollution as the ocean environment at following this harbour of explaining.
Water ballast layout that all modern boats and ships are integrated comprises pump, strainer, pipeline, ventilation installation and storage cabin.Water ballast tank can be between the ship skin in the double wall hull, but also can be any other void space or be suitable for the space of this purpose.When all or part of its goods of unloading of boats and ships, it will travel to another harbour to load another part goods aboard ship.Be under the situation part sky or empty during return in cargo hold or storage cabin, can fill ballast tank for water, thereby stablize boats and ships at sea, to guarantee thruster and the suitable submergence of rudder, realize rational boats and ships balance (trim) and/or guarantee being no more than about the restriction on any structure of ship structure integrity.Ballast tank uses near the seawater water port of debarkation, supply harbour (the donor port) to fill usually.When arrive it will receive new goods be subjected to the goods harbour time, water ballast is entered on every side marine.
The whole world transportation of this water ballast causes the concern to its environmental influence.When filling ballast tank with the water at harbour, this water will comprise the representational organism at a large amount of supplies harbour.Can be larva, fish, mollusk or other the living organism of sea grass, algae, fish, different types of parasite, bacterium and virus etc.When another harbour in the world gave off, these organisms may find the microhabitat that is not occupied and begin breeding and do not have a natural enemy in the ecosystem.Introduced the plant and animal species and caused serious problem in the known environment beyond its natural place of production in new zone.
In order to reduce the danger of introducing the extraneous water biological species, intergovernmental administrative mechanism has been worked out the International Usage of International Usage-ballast water for ship and sedimental control and management.Think that this is the important step of protection species diversity.According to these regulations, newly-built boats and ships must possess the device of processing ballast on the ship, thereby beginning in white 2009 guarantees the water ballast standard of performance of qualification at discharge point (being subjected to the goods harbour).All boats and ships met identical requirement since 2016.Also there is not at present effective, the feasible technology that is used for facility peculiar to vessel to come according to aforementioned regulations processing ballast.Some Treatment of Industrial Water technology can satisfy the processing quality that is provided with in the convention, but may have with ship on use incompatible characteristic or even can not be incorporated in the boats and ships.
Except the water ballast in high sea exchanged in the art, filtration was the most frequently used and simply reduces the method for undesired organism concentration in the water ballast.Most of merchant ships pass through 15 millimeters screen cloth or analogue sieving water ballast at sea valve chest (sea chest) and/or hull fittings place.This simple screen filter can combine with cyclone separator.But, this filtration/separation structure can only be removed bigger organism, for example fish, invertebrates and macrophyte, and other is for the typical organism of water ballast, for example the ovum of bacterium, virus, fungi, protozoon, planktonic organism and Geng Gao life form and larva will pass through.
Cyclone separator is based on the principle work of fluid (being water ballast in this case) and particle (species/organism of existence) density variation.For ballast water application, this species diversity does not always exist.Therefore, cyclone separator is not feasible for water ballast separation application.
The strainer of fine mesh can be removed ovum and larva and big planktonic organism and protozoon fully.But these strainers will produce the back pressure that increases, and can stop up soon during operation and verified being not enough to filtered water ballast under described flow velocity.
In the water ballast on high sea exchange is measure at present unique aggressive ship that is used for processing ballast jump operation risk.Water according to high sea comprises lower organism concentration than seashore that is used for ballast or harbour water, and therefore to being subjected to the goods harbour to have the hypothesis of lower danger, the principle of this practice is simply to dilute principle.
From No. the 5th, 932,112, the United States Patent (USP) of authorizing Browning, thereby known a kind of oxygen of removing water ballast kills organic system.In vacuum process, remove oxygen, inject waste gas subsequently from the boats and ships machine.Research has shown that deoxidation is very effective for kill animals invader (larva, the young and adult form), but for other species, those biologies that adapt to low-oxygen environments or have the opposing stage particularly, and for example sporangiocyst may be not too effective.Injection comprises high-content CO/CO
2Hot waste gas because can promote to corrode and show as not too desirable.
The WO 03/093176 that authorizes McNulty discloses the system and method for ballast water treatment.Draw water by the Venturi syringe that wherein adds with the oxygen stripping gas of micro bubble.Because the big surface of bubble, the oxygen that exists in the water and stripping gas exchange.Then, water is extracted in the ballast tank, there oxygen is discharged.This system had both had the organic effect of killing, and had the effect of the corrosive of inhibition again.But the same with above-mentioned system, some organisms can be survived from handle.
Norwegian Patent 314625 (Forinnova AS) has been described by set up the method that oversaturated gas condition comes processing ballast in water.When fish was exposed in the oversaturated water of gas, they can produce " bubble disease " (gas bubble disease), were also referred to as " caisson disease " (divers ' disease).Oversaturated gas will be replaced the oxygen in the blood, and produce bubble in blood and bodily tissue.Preferred gas is air, but it is generally acknowledged in some applications and can use nitrogen.Supersaturation will be killed bigger organism effectively, fish (organism) for example with recycle system, but for little organism, for example planktonic organism is not too effective or invalid.
Therefore, need day by day to reduce or to eliminate the technology that causes biological pollution by the water ballast of discharging.
Summary of the invention
From an aspect, the invention provides a kind of ballast water processing, it comprises: (for example Zhou Wei sea, lake or river) draws water to water transport (water-going) ship and vessel by strainer from the water source; The level of the dissolved nitrogen content that improves the described water of at least a portion to its nitrification content, thus the water in the described ballast tank is on its nitrification content and under the oxygen saturation content when end is drawn water; In the headspace of described ballast tank, keep atmosphere greater than atmospheric nitrogen content (mole %); From described ballast tank with in the water of water suction around the described boats and ships; And stand the microorganism killing effect before making in the described water of water around it enters described boats and ships of from described ballast tank, extracting out.
From another aspect, the invention provides a kind of treatment facility of waterborne vessel water ballast, described equipment comprises: first pump, it is used for drawing water to ballast tank by strainer; Strainer is drawn water by described first pump by described strainer; Conduit, it is used for delivering water to described ballast tank by described strainer from described first pump; The nitrogen introducer, it is used for introducing nitrogen to the water that is extracted into described ballast tank by described first pump; Randomly that be connected or attachable source nitrogen with described nitrogen introducer; Second pump, it draws water from described ballast tank and makes water pass through conduit and discharge described boats and ships (can randomly and preferably described first pump); And the microorganism killing device, arrange that it is to kill the microorganism in the water of extracting and discharge described boats and ships from described ballast tank out.
From another aspect again, the invention provides a kind of waterborne vessel with water ballast tank, it is characterized in that described boats and ships further comprise the equipment that is used for processing ballast according to of the present invention.
When the nitrogenize of the water ballast in the ballast tank of will packing into have kill carry secretly in the water ballast or ballast tank in the unicellular or multi-cell organism that exists main do the time spent, the further advantage of method and apparatus according to the invention is the corrosion that the oversaturated water ballast of nitrogen also is used to reduce ballast tank.Because repairing or changing the corrosive water ballast tank is one of the most expensive project in the trimming of boats and ships, so this is particularly advantageous.
The corrosion of water ballast tank has greatly limited the work-ing life of boats and ships.At present, the operator of fleet attempts to prolong by the internal surface of paint ballast tank the work-ing life of boats and ships.This is expensive and difficult task, particularly must remove a large amount of mud and residue from ballast tank before painting them.
At least for the above reasons, the corrosion and/or the oxidation of the protective coating in the water ballast tank (for example paint) are the things of whole world steamship company major concern.Ballast tank is the important structural elements of any boats and ships, and the life-span that will endanger the structural integrity of boats and ships and limit boats and ships effectively of the corrosion in these zones.Ballast tank initially scribbles the erosion shield system.By the continuous variation that exposes between water and air, coating is weathering and degeneration gradually in time, until approximately changing behind the 5-10 usually.From that time, just constantly there be repairing, the peeling paint of ballast tank and repaint.This can be undertaken by the engagement of crew on the ship in generation during the repairs of ship repairing yard or between by the harbour.In some boats and ships, particularly have the boats and ships in days, can not paint to ballast tank.
Main mechanism of corrosion is when metal object is exposed in the environment of oxidisability, under moistening or moist condition electrochemical reaction takes place usually.Corrosion in the ballast tank is owing to the steel of boats and ships cabin structure and as the electrolytical sea brine that contains, and oxygen contact airborne or that be dissolved in the water is caused.The coating degradation rate that has the Several Factors influence to cause by oxidation and corrosion.Usually on the outside face of coating, in the top of top ballast tank, find the highest erosion rate.This can by increase by the Exposure to Sunlight medial temperature, the splashing and cause the cycle condensation of water and the combined effect of exsiccant cycle temperature variation to be explained of abundant oxygen (air) supply, seawater.
The development of anticorrosive measure has produced the improved erosion shield that is subjected to change in the environmental legislation (some toxic compounds is used in restriction) influence, and the formulation of implementing many parts epoxy and other coating better.Research has shown when ballast tank when being full, can realize corrosion reduction about 90% comprehensively in the ballast tank by making the water ballast deoxidation.If can further strengthen this effect when when ballast tank is sky, also reducing oxygen level.By directly using " stripping " gas to ballast tank, for example nitrogen can be realized deoxidation.For the gas of replacing dissolved oxygen efficiently, it must more easily dissolve in water than oxygen.
Very clear all respects of the present invention provide the solution of ballast tank etching problem.
Be used for pack into ballast tank and can be conventional ballast pump also usually of water ballast according to of the present invention from the pump of ballast tank discharging water ballast.Although can arrange this pump in service boats and ships (servicevessel), dock or the other places except that boats and ships, it is preferably aboard ship installed.These pumps have 100-12000m usually
3/ hour, 400-1000m for example
3/ hour capacity.
The strainer that the water ballast that enters passes through preferably has for staying the enough little aperture of multi-cell organism.If desired, can use enough little of the aperture that stays bacterium.Strainer has 10-100 μ m, the especially aperture of 20-50 μ m.Preferred filters is the mechanical filter of automatic back flushing.By before or after the strainer, can in water ballast, introduce nitrogen.But it is preferred introducing after by strainer.
Nitrogen can be introduced in the water ballast of part or all inflows.In some embodiments of the present invention, have been found that a nitrogenize part stream of ballast water is more cost effective.Therefore, have been found that, introduce nitrogen in the current of preferred 8-30%, can obtain very satisfied result if separated flow to the water of ballast tank and to one of isolating current, for example comprises the 5-80% of total water current.But, the amount of introducing nitrogen preferably makes the nitrogen of when the stopping pumping water ballast in the ballast tank saturated at least 110%, more preferably saturated at least 120% nitrogen, more preferably saturated at least 130% nitrogen again is for example saturated up to 135% or even 145% nitrogen.The preferred nitrogen content of using the gas dissolved transmitter to monitor water ballast in the ballast tank continuously or discontinuously.During transportation particularly preferably, promptly when discharge of ballast water, monitor nitrogen content.Use is up to the oversaturated water ballast of 145% nitrogen, and the supersaturation of keeping nitrogen in airtight ballast tank was easily promptly navigated by water the sufficiently long time for great majority to 10-15 days.
The nitrogen syringe that uses in the method and apparatus of the present invention can be that nitrogen is introduced in the water to realize the oversaturated any appropriate device of nitrogen, for example supplies with the perforated tube of nitrogen overpressure.But preferred especially syringe is the Venturi syringe, and promptly the contraction section of water pipe has the nitrogen injection port on the wall of this section.For example, a kind of this Venturi syringe has been described in US-B-6505648.Preferably in pipeline, under the pressure more than the pressure of water, nitrogen is sent into inlet.But, nitrogenize part total water current and arrange that it is particularly preferred by described structure that another pump forces water only when using the Venturi syringe.Typically, according to pump capacity, the nitrogen flow rate at this Venturi syringe place can be 10-220m
3/ hour, preferred 25-100m
3/ hour, 35-80m especially
3/ hour.
Although preferred pure substantially nitrogen (at least 90% the N for example that uses
2, at least 95% N especially
2, at least 99% N more particularly
2) as the charging to the nitrogen syringe, as long as the content of acidity or oxidizing gas (for example oxygen or oxide compound) is low, more the nitrogen of low-purity is acceptable.Usually, the nitrogen content of preferred feedstock gas is 85% or bigger.Therefore, can use the mixture of nitrogen/noble gas, but this neither be rational economically.Especially preferred oxygen level is less than 15%, particularly less than 10%, more especially less than 2%, especially less than 1%.Nitrogen supply (NS) to the nitrogen syringe can be to carry out on the ship or under the ship once more.On the ship supply normally preferred because it can be supplied to ballast tank with further nitrogen in transit ideally.Supply can be taked any form easily, for example nitrogen gas generator, pressurized gas storage tank, liquefied gas storage or the like.
If do not use the compression or tank for liquefied gas, preferably in the nitrogen supply (NS) circuit in conjunction with pump and/or heat exchanger.
Before loading water ballast, during or afterwards, can use nitrogen (perhaps other Poor oxygen gas) to wash ballast tank if desired.The headspace of ballast tank also preferably is equipped with gas sensor, particularly nitrogen and/or oxygen sensor, thereby guarantees that during transportation headspace is a hypoxgia with respect to air.Alternatively, gas sensor can be positioned at the outside of ballast tank and be arranged to from the inner sample that receives of ballast tank.If oxygen content raises, can increase a nitrogen content of headspace by adding nitrogen.So, can reduce the ballast tank corrosion.Also particularly preferably be and make empty or the empty ballast tank of part maintains under rich nitrogen, the anoxybiotic atmosphere, thereby even in not having the situation of water ballast, also can suppress corrosion.
In order to improve the thing effect of killing livestock of the ballast water treatment that just is loaded in the ballast tank, preferably in the water pipe from the ballast suction to the ballast tank, add further microorganism killing device.It can be about the described microorganism killing device of discharge of ballast water (and in fact even can be same device) as following; But at the inner cavitation producer that uses of this water pipe, for example thruster (perhaps their forward position analogue) is especially preferred.Heat and more particularly chemical treatment be not preferred.
Ballast tank preferably is equipped with valve, makes can to discharge the overvoltage of headspace and for example by allowing air or more preferably being that nitrogen enters and can proofread and correct negative pressure in the headspace.Typically, by 40-120mmH at least
2O, more preferably 50mmH at least
2O, for example about 60mmH
2O starts this valve with atmospheric pressure difference.When pressure difference during less than preset bounds, valve should cut out.A valve can react to overvoltage and negative pressure, perhaps can use the combination of valve that overvoltage is reacted and the valve that negative pressure is reacted.
Arrange in the pump back preferably that also aperture or mesh size are not more than 2mm, preferably are not more than the thicker strainer of 1mm.Also preferred at the admission port place of water ballast, promptly coarse filter or grid or screen cloth are arranged in the place that enters from water source (for example seawater, lake or river) on every side of water ballast, thereby prevent to suck fish, weeds, perhaps other bigger residue.
In the time will carrying out the discharging of water ballast, use ballast pump to extract water ballast out ballast tank, pass microorganism killing device and nitrogen initiator and enter around water in.The microorganism killing device is used for killing microorganism survival and that during transportation grown when water ballast loads in ballast tank.Can use any suitable microorganism killing device, not realize the device of its biocidal effect but preferably do not use by adding microbicidal chemical reagent.The representative instance of appropriate device comprises that the water with discharging is exposed to electric shock, irradiation, ozone, heating, the perhaps device of pressure change, for example ultraviolet ray or ultrasonic irradiation, electric shock (are for example used AC or DC 100-500V, 200-300V typically, and, 20-50Amp for example), Venturi ozone injection device, cavitation apparatus or the like up to 150Amp.Using electrical treating is a particularly preferred embodiment.
In particularly preferred embodiment of the present invention, equipment comprises the oxygen introducer of arranging to introduce oxygen from the water ballast of ballast tank discharging.So, can discharge the approaching water of oxygen level of the ambient water that oxygen level and water ballast will drain into.This will prevent for the aquatic organic unfavorable influence in locality.The oxygen introducer can be taked any form easily, and for example as described in to top nitrogen introducer, but the Venturi introducer is preferred.The oxygen introducer typically can use from source of oxygen, for example the oxygen in Jia Ya storage tank or air or the oxygen-rich air.For example, can use oxygen level up to 40% oxygen-rich air.Alternatively, the oxygen introducer can receive the oxygen air inlet from nitrogen gas generator.Microorganism killing device in equipment relates in the situation that nitrogen is introduced or other oxygen-depleted gas is introduced, and described oxygen introducer will be preferably placed at the downstream of killing device.
At gas introducer (N for example
2Perhaps O
2Introducer) downstream, water pipe preferably can comprise static mixer, for example with flow to+and-45 ° of corrugated baffles of alternately arranging with fold, described in WO 03/016460.
The boats and ships of treatment in accordance with the present invention water ballast can comprise a ballast tank or a plurality of, normally two or more ballast tanks.These cabins can be mark off compartment and described boats and ships can provide the pump that during transportation between ballast tank or separation, shifts water ballast.If this is the case, preferably this equipment provided before this transfer, during or afterwards nitrogen is introduced device in ballast tank or the separation headspace.In addition, this transfer pumping circuit if desired can be in conjunction with the nitrogen syringe to keep the nitrogen supersaturation of water ballast.
Although as mentioned above, the nitrogenize water ballast in the ballast tank of will packing into most preferably, filter, especially fine pore is filtered (for example using filter bag), with from the ballast suction to the ballast tank and/or the microorganism killing device of arranging the water pipe from ballast tank to the discharge of ballast water mouth, especially to kill the combination of device itself be novel to electricity (for example electric shock) and formed another aspect of the present invention.Therefore, from this aspect, the invention provides the method for ballast water treatment, it comprises: (for example Zhou Wei sea, lake or river) draws water to the ballast tank of waterborne vessel by strainer from the water source; With water from the water of described ballast tank suction around the described boats and ships; And make take out toward described ballast tank and before in the water of the described ballast tank described water around being released into described boats and ships, stand the microorganism killing effect.
From another aspect again, the present invention also provides the equipment that is used for the waterborne vessel processing ballast, and described equipment comprises: first pump, and it is used for drawing water to ballast tank by strainer; Strainer is drawn water by described first pump by described strainer; Conduit, it is used for delivering water to described ballast tank by described strainer from described first pump; And the microorganism killing device, arrange its with kill take out toward described ballast tank and from the microorganism in the water of described ballast tank.
In this method and apparatus, be preferably included in once more in the discharging forward direction water ballast and introduce oxygen, thereby the discharging of avoiding the anoxic water ballast is to aquatic organic unfavorable influence then and there.
Another aspect of the present invention disclosed herein relates to compares in killing water ballast the method for more effective processing ballast and layout aspect the unfavorable organism with aforesaid art methods, and the protection that the corrosion in the ballast tank is improved is provided.
Therefore, from an aspect, the invention provides the method for processing ballast, described method comprises from first water receiver draws water; Xiang Shuizhong adds steam; Xiang Shuizhong adds other gaseous material; In water, introduce cavatition; With water is transported in second water receiver.
From another aspect, the invention provides the layout of processing ballast, it comprises the pump that draws water from first water receiver, it is characterized in that described layout comprises that Xiang Shuizhong adds the device of steam; Xiang Shuizhong adds the device of other gaseous material; In water, introduce the device of cavatition; Water is transported to the device of second water receiver.
From another aspect again, the invention provides the device of the processing ballast that is used for arranging as defined above, it is characterized in that described device comprises the liquid inlet duct of supply water ballast in fluid treatment appts, the intake chamber that is connected with described inlet tube, the conical section that is connected with described intake chamber, the pipeline that is connected with described conical section, cavitation cell with described pipe connection, that be connected with described cavitation cell and from the liquid outlet tube of described cavitation cell fluid transfer, and at least one is to the air-supply duct of described intake chamber supply steam and other gaseous material.
From another aspect, the invention provides the device of the processing ballast that is used for arranging as defined above, it is characterized in that described device comprises in fluid treatment appts the liquid inlet duct of supply liquid, the conical section that is connected with described inlet tube, the cavitation cell that is connected with described conical section, be connected with described cavitation cell and device supply steam and other gaseous material from the liquid outlet tube of described cavitation cell fluid transfer, to intake chamber.
System based on cavitation is exposed under the extreme physical condition consistent with the pulse shock that destroys bio-tissue and cytolemma effectively (pulsed shock waves) organism that exists in the water ballast.Integrated artistic will and can be set up the atmosphere of the intimate anaerobic of controlling except that the most of oxygen of dissolved in anhydrating in ballast tank.But the atmosphere that is close to anaerobic will further be eliminated and may survive from pulse shock any organism that the remaining oxygen of needs is survived, and play a part to prevent any other organism potential regrowth.It also will reduce the surface oxidation of any corrosion protection coating in the cabin or paint system, and make erosion rate reduce about basically 90% or even bigger effectively.Anaerobic atmosphere in the ballast tank will be eliminated the danger of exploding in described cabin; This is particularly suitable for delivery oil or pharmaceutical chemicals or any boats and ships that may produce any other goods of explosive atmosphere at term of voyage.As the result of the device that is used for from water, removing dissolved oxygen, will become supersaturation and therefore make organism of water, the organism that particularly has the complex loops system is exposed in the bubble illness.Proved that by different research mortality ratio is high.The verified organism that other has a not too complicated recycle system also is vulnerable when being exposed to supersaturation following time.Particularly in the situation that degree of super saturation increases.
In a word, when entering, discharging or entering and discharge, use the steam that comprises the oxygen stripping gas to the water ballast circuit at decanting point or near the decanting point place.This will produce suction or prograding, be used for water ballast being transported to equipment and increasing the fast interior pressure that reduces water thus that reaches of water.Described steam and gaseous mixture will change the characteristic that gaseous state is formed and therefore change comprises its vapour point of water.At certain some place of process, pressure will reach the level of generation cavitation or near this level, produce the extreme physical condition consistent with pulse shock.These conditions will be destroyed most of organism in the water.
Inject the combination of the steam gas of water and will replace the most dissolved oxygen of water.Cavatition self will strengthen the deoxidation process, cause remaining in the further reduction of the oxygen content in the water.After cavitation, fluid will be a biphase: liquid and gas.
Because liquid phase will be saturated or oversaturated, so mainly the gas phase of being made up of the oxygen that discharges will keep stable and will can not dissolve back in the liquid phase.
The replacement of oxygen will promote to kill the organism of having survived in the treating water in the cavitation step, and the protection ballast tank is not subjected to corrode and coating is not oxidized.Add steam and will advance water to flow through, therefore realize obtaining the required flow velocity of stable cavatition in the mode of energy efficient.This will not need excessive pump.Because will promote in water, to form a large amount of small bubbles, and this has represented big surface-area, so this also is useful to oxygen exchange.Use steam to be considered to than art methods more efficiently as medium gas dissolved in liquid.
Gas will be gaseous material, and outside promptly dewatering is certain material of gas under standard atmospheric pressure (STP).For treating water when sucking, gas should contain less than 15 moles of %, preferably less than 10 moles of %, if perhaps feasible, less than 5% or less than 1% oxygen, all the other are nitrogen or noble gas.When discharging, gas should preferably comprise the oxygen greater than 15 moles of %.
Therefore, suction from seawater and in being transported to ballast tank or discharge outboard treating water efficiently in the time span of obtainable weak point.Eliminate or some other required characteristic for the species of realizing higher degree, this process can combine with other handling principle, equipment or method.This may relate to the reception facilities at discharge of ballast water mouth place.
As mentioned above, be that the water that delivered in ballast tank before its purpose goods of ship loading drains into marine greatly for the common way of boats and ships.The state's laws of the countries concerned have defined boats and ships must discharge the distance of water ballast place apart from seashore.For example, Canadian legal definition the boats and ships ballast tank water of finding time be 200 nautical miles apart from the distance of seashore.
By attempting to determine whether found time seashore authorities evaluation the observing of the countries concerned of ballast tank of the suitable distance of distance seashore to these requirements.At present can not be in the opinion of observing the ship and vessel that confirms under the relevant law to have found time, be owing to require the find time distance at ballast tank place of boats and ships at least.
Therefore need a kind of system, it helps seashore authorities to determine whether to have observed the concerned countries law.
Therefore, another aspect of the present invention disclosed herein provides the water ballast Controlling System, it comprises control unit and data storage equipment, described control unit is set with the indication that receives the water ballast tank of having found time and the indication and the described two kinds of indications of storage in described data storage equipment of boats and ships coordinate.
By the inquiry data storage equipment, definite discharging ballast tank crystal is provided the method for true position for seashore authorities.
Control unit and data storage cell can be any suitable layouts.For example, can provide the conventional data storage equipment that has, for example the minicomputer of hard disk drive etc.Alternatively, can and be integrated in the ship control system this system's combination.
If desired, data storage equipment can and can be stored with the water ballast of more than one boats and ships away from boats and ships and enter and/or discharge relevant data.An example of this system is the database that the internet can insert.
Can use any proper device to determine vessel's position.Preferably, in order to guarantee precision, use global positioning system (GPS) (GPS) that the coordinate of boats and ships is provided to control unit.Can be by providing the coordinate of boats and ships with the marine navigator communication.Alternatively, for example can use other technology to provide or definite position with transmitting set triangulation.
Control unit can be by from the control signal discharge of ballast water pump or Controlling System, for example represents that ballast tank is empty or the signal of having found time determines that ballast tank finds time.Alternatively, control unit can receive and for example represents the signal that ballast tank has been found time by the substantial variations of liquid level from being arranged in water ballast tank or near liquid level sensor or other right sensors.
Preferably, the found time signal of ballast tank of expression is or comprises the indication in the cabin of finding time fully.For example, this can be that timing register by water level sensor or expression emptying pump runtime carries out.
Preferably at data storage equipment, for example storage the found time indication of ballast tank and the indication of position of ship when ballast tank is drained in database.
Can also arrange that control unit and data storage equipment write down the time of the time of unloading, loading, water temperature etc.Use suitable transmitter, can also arrange control unit and data storage equipment write down in the ballast tank the water ballast condition or about the out of Memory of water ballast, for example salinity, N
2Content etc.Can in the whole voyage of boats and ships, write down and store these information.
Provide about the information of particular country law can also for database and/or control unit and can be provided with and show by relatively vessel's position and law and whether to have observed law.Therefore, seashore authorities can determine easily whether boats and ships have observed law.
Preferably, seashore authorities can also long-rangely obtain the boats and ships data by suitable communication link (communication link), make that seashore authorities needn't be at boats and ships investigation boats and ships before stop at the harbour.
The boats and ships data directly can be sent to seashore authorities or send the third party that can represent seashore authorities verification msg alternatively to, notify seashore authorities then in view of the above.For instance, this third party can be the tissue of DNV for example.Deposit at this cloth, for example follow the tracks of via satellite etc., can determine vessel's position independently with the boats and ships data.
As mentioned above, deposit, can use ballast tank or near proper sensors the condition that is arranged at the voyage monitoring water ballast of boats and ships at a kind of cloth.So, the condition that can keep in the ballast tank is in optimum level.
But particularly when being positioned at ballast tank, transmitter is the easy deterioration of after date when the operation that prolongs.
Therefore, in order to overcome this problem, it is outside and use suitable conduit or a plurality of conduit to be connected with cabin realization fluid that transmitter is preferably placed at ballast tank.The preferred arrangements transmitter returns water ballast in the ballast tank, thereby keeps the volume continuous monitoring simultaneously water ballast condition of ballast tank.
Therefore, from another aspect again, the water ballast tank monitoring equipment is provided, and it comprises that at least one has the conduit of first end that is positioned at water ballast tank and second end that is communicated with at least one transmitter fluid, and wherein said at least one transmitter is positioned at the outside of described water ballast tank.
Can placement sensor monitor many parameters, for example oxygen level, nitrogen content, salinity, pH and temperature.Thereby, can in prolonging period, monitor the variation in water ballast and the ballast tank nearly.
Transmitter can receive water ballast from a plurality of conduits that end is arranged on the ballast tank different positions.The preferred arrangements transmitter is from each ballast tank and particularly receive water ballast from the ballast tank cavity of common the most unattainable bottom of ship.
Water ballast can be communicated with transmitter to the A/C that the ballast tank each several part extends from transmitter by many.Alternatively, transmitter can be connected with one or more extendible conduit that is arranged to extend in the ballast tank, thereby can receive water ballast from the specific position in the ballast tank.Deposit at this cloth, can arrange that conduit moves being fixed on liner on the ballast tank or the track, thus guide catheter around exactly in the cabin.
This layout can also be connected with above-mentioned water ballast control unit, thereby permission is monitored the interior condition of ballast tank and mated with GPS and time data.
During the loading and unloading of ballast tank, it is important when water level changes gas being entered or discharging in the cabin.Traditional boats and ships possess can open the ballast tank valve that makes air movement.In addition, need be provided at the valve that allows thermal distortion in the cabin in the boats and ships voyage.For example, entering the torrid zone will increase temperature in the ballast tank, thereby increase the pressure of headspace.Ship classification association requires to ventilate fully and avoids pressure to increase (or insufficient pressure).
As disclosed herein, in ballast tank, introducing in the situation of nitrogen, also need when introducing nitrogen, make air leave ballast tank.
