DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pollutant disposal ship for burning waste (hereinafter referred to as "pollutant") such as crude oil deposited on the bottom of rivers, swamps and lakes in water. More particularly, the present invention relates to a pollutant handling vessel for treating the pollutant by a multi-phase multi-electrode plasma arc generator and converting the pollutant into a non-polluting one.

[0002]

2. Description of the Related Art In recent industrial activities, petroleum is used in large quantities as an energy source and a raw material for various products, and the scale of oil mining and refining in oil-producing countries has become extremely large. However, with the expansion of the mining / refining scale, accidents related to the processing and work related to it have also occurred frequently, such as heavy oil spills due to tanker accidents and heavy oil spills due to damage to oil refinery facilities. The heavy oil spilled by this is accumulated in large quantities so as to stick to the bottom of the lake due to oxidation and the like. As a result, rivers and lakes are increasingly polluted and the organisms that inhabit them no longer are almost contaminated, and the use of water from these rivers as drinking water requires expensive purification equipment. There is a problem that it cannot be used as a drinking water source as it is.

[0003]

SUMMARY OF THE INVENTION The present invention relates to an environment in which polluted sludge such as heavy oil deposited on the bottom of a river, swamp, lake, or sea bottom is incinerated and melted at the bottom of the water so that the polluted environment has no inherent pollution. While being able to recover to the natural environment,
It is an object of the present invention to provide a pollutant disposal ship capable of recovering various gases including water vapor generated during the pollution treatment and producing distilled water.

[0004]

A pollutant disposal ship according to the present invention is provided in a hull so as to be able to move up and down between the hull and the water bottom, and is lowered until it reaches the water bottom so that the pollutant on the water bottom is provided. An incineration housing having a plasma arc generator for directly incinerating the plasma arc by generating a plasma arc, a power supply for supplying a multi-phase or single-phase AC voltage or a DC voltage to the plasma arc generator, and a plasma arc at the water bottom And a distilled water generating apparatus that collects various gases including water vapor generated by burning and melting the pollutant and water in the water, and condenses only the water vapor to generate distilled water.

Further, in the pollutant disposal ship according to the present invention, a plurality of electrodes are mounted on a large-diameter portion having a diameter larger than a pipe body formed at a tip of the pipe member as the incineration housing, and an upper end of the pipe member is provided on In order to reduce the flow velocity of the gas flow that has risen inside the pipe member, a large-diameter portion whose diameter is larger than the diameter of the pipe member is formed.

Further, in the pollution control vessel according to the present invention, the pipe member is connected to an extension pipe member by using a hanging mechanism such as a crane so that the length thereof can be extended. Is stored in a predetermined space in the hull.

[0007]

According to the present invention, the combustion housing is lowered from the hull, and pollutants on the water bottom are generated by a multi-electrode plasma arc generator provided in the combustion housing, and are directly processed at a high temperature. Pollutants at the bottom of the water can be completely eliminated.

[0008] Further, the generation of the plasma arc causes generation of various types of wave energy including combustion heat, electromagnetic vibration, shock waves, ultrasonic waves, and far-infrared rays in the water. Since the water is generated, distilled water can be generated at the same time as the combustion treatment of pollutants at the bottom of the water, and it can contribute to securing drinking water in an area where drinking water is scarce such as the Middle East.

At the upper end side of the pipe-shaped member constituting the combustion housing, a large-diameter portion larger than the diameter of the pipe main body is formed, and at this portion, the flow velocity of the gas rising in the pipe with violent force is formed. Since the gas is reduced, foreign matter contained in the gas can be trapped at the lower end of the large-diameter portion.

And the winches 502 and 503 that are arranged on the deck at the foot of the gantry 501 and connected to the incineration housing to wind or unwind the wire.

Next, devices 300a and 300b for recovering a gas containing water vapor generated by the generation of a multi-arc at the water bottom and generating distilled water will be described. However, since the stern-side device has the same structure as the bow-side device, only the bow-side device 300a will be described. This distilled water generator 3
00a is a hollow spherical tank 301 and the spherical tank 3
And a gantry 310 for mounting the gantry. Here, a nipple member 302 for connecting a pipe is attached to an upper side surface of the spherical tank, and a joint device 302b is attached to the nipple member 302 via a 45-degree elbow 302a. The joint device 302b further includes the incineration housing 20.
A connecting pipe 302c for connecting the distal end side of the pipe member 210a and the distilled water generating apparatus 300a is rotatably mounted, and a distal end portion 302d of the pipe 302c has a bellows shape that can be extended and contracted. ing. A first gas extraction hole 303 for extracting light gas accumulated in the spherical body is formed at the top of the spherical tank 301, and a second gas extraction hole 303 for extracting heavy gas is formed on the upper side surface of the spherical tank 301. A gas extraction hole 304 is formed. A distilled water outlet 320 for removing condensed distilled water is attached to a portion directly below the spherical tank 301, and a valve 321 is provided at the outlet.

Next, the operation will be described. This pollution treatment vessel 100 sails to the water area where pollutants are deposited,
Then, work on the treatment of pollutants is performed. That is, first, upon arriving in the water area, the hull is fixed at a fixed position by an anchor, and then the incineration casings 200a and 200b are lowered to the bottom of the water. At this time, the extension pipe 600 is
0a is taken out by a crane 700, connected to the pipe member 210 of the incineration case 200a, and then the winches 502 and 503 are driven to lower the incineration cases 200a and 200b until the lower end side cover 240 contacts the bottom of the water. . At this time, the power supply cable 401
Is fed by the cable feeding device 410 as the incineration housing descends. Then the above extension pipe 6
00 at the upper end of the bellows portion 302 of the connection pipe 302c.
By connecting d, the pipe member of the incineration housing and the spherical tank are connected.

In this state, the power supply units 420a, 42
0b to drive the electrodes 25 of the incineration cases 200a and 200b.
A three-phase AC power is supplied to 1a to 253a to generate a multi-arc. Then, the polluted substances deposited on the water bottom are burnt and converted into harmless ceramics and the like by the multi-arc. When the combustion process at the first stop position is thus completed, the incineration cases 200a, 200
b is slightly lifted, the hull 101 is moved in this state, and the same processing as described above is performed at this position. Thus, pollutants such as heavy oil deposited on the water bottom by the multi-arc are burned over the entire water bottom in the surrounding water area.

In such a multi-arc combustion process, the temperature of the multi-arc generating portion becomes extremely high, and the water of the multi-radial generating portion and the vicinity thereof boil. As a result, a large amount of water vapor and other various gases are generated, and these gases are burned in the water by passing through the pipe member 210 through the gas insertion holes 240a formed in the lower end side cover member 240 of the incineration casings 200a and 200b. While rising. The pipe expanding member 2 at the upper end of the pipe member 210
At the position where the pipe 20 is mounted, the diameter of the pipe is widened at this portion, so that the gas ascending flow velocity is reduced, and foreign matters such as solids contained in the gas are removed by the pipe expanding member 22.
0 is trapped in the lower ring-shaped member 260. Then, the gas further rises and passes through the extension pipe 600 and the connection pipe 302c to produce the steam generators 300a and 300b.
Will be collected.

When the gas generated at the bottom of the water flows into the steam generator, its temperature is considerably lowered, and the steam component is condensed to become distilled water and accumulated at the bottom of the spherical tank 301. The light gas is sent to a gas recovery device (not shown) via the first gas extraction hole 303, and the heavy gas is sent to a gas recovery device (not shown) via the second gas extraction hole 304. When the river, swamp, or lake is deep, the above extension pipe 600 is further added to incinerate the
00a and 200b can be lowered to the bottom of the water.

When the multi-arc treatment in the water area is completed, the incineration casings 200a and 200b are wound up by winches 502 and 503, and the extension pipe 600 and the extension pipe 600 are displayed with the extension pipe 600 completely appearing on the ship. The lower pipe is removed, and the extension pipe is stored in the storage 600a by the crane device 700. Further, the winch is wound up and the incineration housings 200a and 200b are housed in the hangars 101a and 101b of the hull. Then, the extension pipe connected to the upper end of the pipe member 210 of the incineration case 200 is removed and stored in the hangar 600a by the crane device as described above.

Thereafter, the hull is moved to another body of water that has accumulated on the pollutant. Further, here, the same multi-arc processing as described above is performed to process the surrounding sea area with the multi-arc. When the distilled water in the spherical tanks 300a and 300b reaches the full capacity, the distilled water is poured into a distilled water storage tank (not shown) provided in the hull through the distilled water take-out pipe 320, and the distillation is performed. Empty the water generator. Then, when the hull is full of distilled water, the multi-arc processing is temporarily stopped, and the vessel once calls at a base such as a distilled water treatment facility.

As described above, in this embodiment, the combustion housing 200
Since a and b are lowered from the hull 101 and the pollutants on the bottom of the water are directly generated at high temperatures by generating arcs by the multi-phase multi-electrodes 251 to 523 provided in the combustion housing,
Pollutants at the bottom of the water can be completely eliminated.

Further, since various gases including water vapor are recovered by the heat of combustion due to the generation of the multi-arc to produce distilled water, distilled water can be produced simultaneously with the burning of pollutants at the bottom of the water. Thus, it is possible to contribute to securing drinking water in regions such as the Middle East where drinking water is scarce.

The pipe member 2 constituting the combustion housing
On the upper end side of the pipe 10, a large-diameter portion 211 larger than the diameter of the pipe body is formed, and the flow rate of the gas rising in the pipe with violent force is reduced at this portion. The foreign matter trapped at the lower end of the large diameter portion can be trapped.

In the above embodiment, the spherical tank 300 is used.
Although a and b are supplied with water vapor or the like by gas pressure due to combustion, a pump may be used for this.

In the above embodiment, no special cooling device was provided in the spherical tank of the distilled water generator.
A cooling device may be mounted around the spherical tank 301 by helically winding a pipe for circulating cooling water, and cooling water may be circulated through the cooling device to cool the inside of the spherical tank 301.
