Description of drawings
Now with reference to accompanying drawing, introduce preferred implementation of the present invention, in the accompanying drawings by the mode that does not only have any restricted intention as example:
Fig. 1 is mounted in the scheme drawing of the ballast water treatment plant of the first embodiment of the invention in the oil tanker;
Fig. 2 shows pipeline and the valve bonded assembly scheme drawing in the ballast water treatment plant among Fig. 1;
Fig. 3 is mounted in the scheme drawing of the Waste Heat Recovery System (WHRS) in the ballast water treatment plant among Fig. 1; And
Fig. 4 is mounted in the scheme drawing of the ballast water treatment plant of the second embodiment of the invention in the common ship.
The specific embodiment
With reference to Fig. 1, oil tanker 2 has oil cargo tank 4 and ballast tank 6.Seawater inlet 8 is provided with and is used to remove sedimentary filter (not shown), and is connected to each oil cargo tank 4 by first sea water pump 10, seawater pipeline 12 and triple valve 14.Triple valve 14 is connected to Cargo Oil pipeline 20 with oily to oil cargo tank 4 loadings and oily from oil cargo tank 4 unloadings by cargo oil pump 16 and another triple valve 18, and is connected to the oil water separator 22 that is used for from the seawater separating oil that is received by oil cargo tank 4.
Isolated oil is sent to dirty oil tank 26 by pipeline 24 from oil water separator 22, is sent to by second sea water pump 28 through the seawater (seawater of by disconnector 22 oil therefrom having been separated just) that cleans to be used for being separated into the fresh water production equipment 30 of fresh water and salt solution through the seawater of cleaning.Fresh water production equipment is connected to by pipeline 32 and is used for salt solution is entered marine salt solution discharge orifice 34, and the ballast pump 38 that is connected to ballast tank 6 (only showing one of them in Fig. 1) and is used for fresh water is discharged by fresh water discharge orifice 40 by triple valve 36.
With reference to Fig. 2, can find out that triple valve 14 is connected to the suction point 46 of each oil cargo tank 4 by Cargo Oil pipeline 42 and cooresponding two-port valve 44.Similarly, triple valve 36 sucks point 52 by the correspondence that ballast water pipeline 48 and cooresponding two-port valve 50 are connected to each ballast tank 6.
With reference to Fig. 3, show and be used for the Waste Heat Recovery System (WHRS) 54 that the ballast water treatment plant with Fig. 1 and Fig. 2 uses together.By means of energy being provided for energy saver/donkey boiler 56, in pipeline 58, produce the high pressure steam that is used for driving pump 10,16,28,38 thus from the unnecessary heat of oil tanker sustainer, main engine (not shown).In addition, cabin heating pipeline 60 provides low pressure steam with the seawater in the heating oil cargo tank 4.
Operation to ballast water treatment plant of the present invention now is introduced.
In order to transport Cargo Oil, oil tanker 2 moves in a usual manner, that is to say that ballast tank 6 is empty, and oil cargo tank 4 is filled oil, in the destination of oil tanker oil is unloaded subsequently.
But when the return of oil tanker began, the unloaded oil cargo tank 4 that still has about 2% to 3% original Cargo Oil in its wall portion was loaded into quantity and is approximately 20% to 30% seawater above ballast tank 6 capacity.During voyage, utilize by Waste Heat Recovery System (WHRS) 54 generations and along the low pressure steam that low pressure cabin heating pipeline 60 provides oil cargo tank 4 interior seawater are heated to 40 to 50 ℃.It will be understood by those skilled in the art that the work efficiency that has just improved oil water separator 22 and fresh water production equipment 30 like this.
Oil is removed from the side of oil cargo tank 4 with help with the wall portion of seawater spraying oil cargo tank 4 subsequently.Make cargo oil pump 16 subsequently and be connected to oil water separator 22 triple valve 18 work so that from the seawater of oil cargo tank 4 through oil water separator 22 and be separated into the oil of recovery and through the seawater of cleaning, the oil that reclaims is sent to dirty oil tank 26, and is sent to fresh water production equipment 30 through the seawater of cleaning by sea water pump 28.
Fresh water production equipment 30 will be separated into salt solution and fresh water through the seawater of cleaning, and salt solution is discharged to marine by salt solution discharge orifice 34, and fresh water is sent to triple valve 36, and triple valve 36 is sent into fresh water in the ballast tank 6 subsequently.Because fresh water production equipment 30 can reclaim about 70% fresh water from seawater, so oil cargo tank 4 can produce 20% to 30% useful loading seawater above ballast tank 6 capacity.The fresh water of gained is exactly vendible commodity subsequently, and it can be discharged by ballast pump 36 and fresh water discharge orifice 40 in the destination of oil tanker.Can utilize suitable controller (not shown) to control the loading and unloading order of cabin 4,6 to keep structure integrity, safety and the stability of oil tanker.
Fig. 4 shows the ship 102 (that is to say and be not oil tanker) of general type, and ship 102 has the water treatment plant of second embodiment of the invention, with parts identical in the embodiment of Fig. 1 to Fig. 3 by similarly but having increased by 100 Reference numeral represents.Ship 102 has cargo hold 104 and ballast tank 106.Seawater inlet 108 is connected to the rough filter of flushing certainly 121 that is used for removing from seawater accretion and bigger suspended material by first sea water pump 110 and seawater pipeline 112.
Delivered to the fresh water production equipment 130 that is used for the seawater through cleaning is separated into fresh water and salt solution through the seawater that filters by second sea water pump 128 from filter 121.Fresh water production equipment 130 is connected to by pipeline 132 and is used for salt solution is discharged to marine salt solution discharge orifice 134, and is connected to ballast tank 106 and the ballast pump 138 that is used for fresh water is discharged by fresh water discharge orifice 140 by triple valve 136.
It will be understood by those skilled in the art that above-mentioned embodiment only is not have any restrictive, sense as the example introduction, and have various modifications and distortion and do not deviate from the protection domain that the present invention is indicated in the appended claims.For example, can use gravity well known to those of ordinary skill in the art/coalescent design-calculated oil water separator 22, perhaps also can use the oil water separator 22 of other types.Similarly, can use the fresh water production equipment 30 of reverse osmosis design, but also can use the fresh water production equipment of other types.
