An ultra-high-temperature arc carrying negative electron ions is generated in the air, various gas atmospheres, and liquids.

Since a heat source of 1000 ° C. or more can be obtained at the same time when the switch is turned on, any substance can be melted and dissolved.

Since a rotating magnetic field is generated at the tip of the electrode, an electric stirring action on the irradiation object can be expected.

The number of phases and the number of electrodes can be increased by a multiple of 3, making it possible to increase the electrode diameter, increase the load current, and process a large-capacity substance in a short time.

Using a three-phase, six-phase, or other polyphase alternating current, the total current of each phase is always 0, and no earth wire is required, so the arc is a non-transitional type that does not require a counter electrode. Since it is not necessary to use this as a counter electrode even for substances other than, a substance without conductivity is directly heated,
Can be melted.

By providing a neutral electrode at the center of the plurality of electrodes, a stronger plasma arc is generated. Moreover, this arc can automatically change the shape and direction of the arc by applying an electromagnetic force.

When the vehicle reaches the target marine position, the berth is anchored there, and the bell 301 of the bell storage unit 3 is lowered to the sea bottom via the vertically movable unit 5 provided on the column 7. And the bell 30
When 1 reaches the sea floor, the three-phase AC power supply 40
A voltage is supplied from 1 to generate a plasma arc between each of the electrodes 309 of the multi-phase, multi-electrode plasma arc generator to burn off pollutants on the sea floor. At this time, the piston 32
2 is driven to excavate the sludge by the shovel 320, whereby the sludge deposited on the seabed can be treated to a certain depth. Pollutants on the sea floor are made non-polluting and activated by this combustion treatment.

Next, the conversion and use of energy by the bell 301 will be described. This multi-phase, multi-electrode plasma arc is enormous in power and generates a strong flame, causing seawater to blow up around it. As a result, the seawater inside the bell 301
It explodes explosively upward through the opening 304 of 03.
As a result, the seawater rises at a high speed, and the four impellers 314 are rotated by the oscillating power of the seawater. These torques are transmitted to bevel gears 315 fixed to one end of each rotating shaft 313. Further, it is transmitted to a vertical output shaft 317 via a bevel gear 316 meshing with the bevel gear 315. Then, the torque of the output shaft 317 is taken into the generator 318 and converted into electric energy. This electric energy is electric wire 3

Next, applications of various pipes provided in the bell 301 will be described. In the bell 301, the pollutant is completely burned by the high temperature as described above, thereby generating O ₂ and H ₂ . The H ₂ is absorbed by the hydrogen absorbing alloy 307 provided in a lower portion of the heat resistance of the support base 306, enters the cooling device 405 of the power supply unit 4 through of H ₂ pipe 504, also, O ₂ is O ₂ pipe The mixed gas enters the cooling device 405 of the power supply unit 4 via the cooling unit 505 and is cooled. Thus, by mixing and cooling O ₂ and H ₂ , distilled water is obtained and supplied to each part in the pollution control vessel.

A CFC pipe 506 spirally wound around the center pillar 302 of the bell has a CFC liquid or CFC gas circulating in the pipe, and a multi-phase multi-electrode plasma generated between the electrodes 309. Heated by the arc and completely vaporized by a Freon vaporizer 403 provided in the power supply unit 4 through a Freon pipe 502, the Freon generator 40
4 converts it into electrical energy. This electric energy is transmitted to the charger 402 via the electric wire 319, stored by the charger 402, and supplied to the electric motor such as the motor 100 via the voltage supply line 101 when necessary. The CFC liquid or CFC used by the CFC generator 404 is recirculated to the CFC pipe 506 through the CFC pipe 503.

09 will be described. When the multi-phase multi-electrode 309 mounted on the electrode support tube 308 of the bell 301 is consumed by generating a multi-phase multi-electrode plasma arc and burning the pollutant, the tip of the electrode 309 is always in a fixed position.
