Definitions

  • This invention relates to a sea-going vessel for disposing wastes, more particularly to a sea-going vessel which is provided with a solid-waste incinerator and enclosed chambers for post-treatment of the products of incineration so as to remove hazardous substances therefrom.
  • An object of the invention is to provide a solid waste disposing sea-going vessel to incinerate dangerous wastes at sea far away from land.
  • Another object of the invention is to provide sea-going vessel with an incinerator and enclosed chambers for post-treatment of the products of incineration, thereby effectively eliminating harmful substances before the incinerated wastes are discharged into sea.
  • a waste-disposing sea-going vessel comprises: a vessel body; at least one incinerator mounted on the vessel body and having a waste inlet and a chimney; a plurality of containers disposed on the vessel body to receive solid wastes; delivery means for delivering the solid wastes from the containers to the waste inlet; a scrubbing chamber having a first spraying unit to spray sea-water onto smoke directed to the scrubbing chamber from the chimney; a smoke -conveying pipe connected to the chimney and the scrubbing chamber so as to direct the smoke from the chimney to the scrubbing chamber; a neutralization chamber connected to the scrubbing chamber and having a second spraying unit to spray an alkaline solution onto the products of scrubbing which enter the neutralization chamber from the scrubbing chamber; and means for discharging the products resulting from the neutralization chamber into the sea .
  • the delivery means comprises a belt conveyor provided at the waste inlet to receive the solid wastes from the containers and to feed the same into the incinerator; a tilting device having a tilting platform to receive and tilt the containers so as to deliver the solid wastes from the containers to the conveyor belt; and a transporting cart to transport the containers to the tilting platform, the transporting cart having a crane to deliver the containers onto the tilting platform.
  • a sea-going vessel 1 is shown to include a vessel body 10, an incinerator 11, a plurality of solid waste containers 12 provided on the deck of vessel 1, transporting carts 13 (only one cart is shown) for transporting the waste containers 12, conveyor belts 14 (only one is shown), tilting devices 15 (only one is shown), a scrubbing chamber 16, and a discharging pipe 17 to intercommunicate a chimney 112 of the incinerator 11 and the scrubbing chamber 16, and a discharge pipe 169 communicated with a neutralization chamber 162 .
  • the incinerator 11 is provided with three waste inlet ports 111.
  • the conveyor belts 14 are provided adjacent the waste inlet ports 111, respectively, in order to feed the solid wastes from the containers 12 into the incinerator 11.
  • Each transporting cart 13 has a crane 131 to lift and carry the containers 12 to tilting platforms 151 of the tilting devices 15.
  • Each tiling platform 151 is operated by a hydraulic lift 152 which is disposed below the tilting platform 151 to perform a tilting operation.
  • a stop member 153 is disposed on each tilting platform 151 in order to stop the containers 12 from sliding downward when the tilting platform 151 is tilted.
  • the scrubbing chamber 161 has a passage 163 which intercommunicates the scrubbing chamber 161 and the neutralizing chamber 162.
  • the scrubbing chamber 161 is provided with a first spraying device 164 to spray sea-water onto the smoke directed into the scrubbing chamber 161 from the chimney 112.
  • the neutralization chamber 162 is provided with a second spraying device 165 to spray an alkaline solution.
  • the discharge pipe 169 is connected to the neutralization chamber 162 via a discharge port 168.
  • the smoke conveying pipe 17 includes a bifurcated portion having two branch pipes 171 and 172 which are respectively connected to the scrubbing chamber 161.
  • the branch pipes 171 and 172 are provided with a secondary burning unit which includes two flame inlet ports 173 and 174.
  • Catalyst converters 18 are disposed in the branch pipes 171 and 172 downstream of the flame inlet ports 173 and 174.
  • Exhaust fans 19 are provided in the branch pipes 171 and 172 to fan the smoke of incineration.
  • the containers 12, which are filled with solid wastes on land, are loaded on the vessel 1 so as to incinerate the solid wastes at sea.
  • the transporting carts 13 transport the containers 12 to the tilting platforms 151 where the containers 12 are tilted to deliver the solid wastes onto the conveyor belts 14.
  • the conveyor belts 14 feed the solid wastes into incinerator 11.
  • the resulting smoke or incineration products flow upward through the chimney 112 of the incinerator 11 .
  • the smoke-conveying pipe 17 directs the smoke which flows upward from the chimney 112 in a downward direction to the scrubbing chamber 161.
  • the exhaust fans 19 function to accelerate the flowing rate of the smoke.
  • the catalyst converters 18 remove additional amount of hazardous particles by filtration and chemical conversion. Since the size and the amount of the smoke particles are reduced upstream of the catalyst converters 18, the service life of the catalyst converters 18 can be prolonged, thereby minimizing the frequency of cleaning operation. With the provision of the catalyst converters 18, the load to be borne at the post-treatment stages can be minimized, and the efficiency of the post-treatment can be increased.
  • the first spraying device 164 sprays sea-water, which contains basic substances, onto the smoke, thereby cooling the smoke and combining the smoke with the sea-water.
  • the products of the scrubbing are led to the neutralization chamber 162 in which an alkaline solution is sprayed by the second spraying device 165 to remove additional hazardous substances.
  • the products resulting from neutralization are discharged into the sea via the discharge port 168 and the discharge pipe 169.
  • any suitable incinerator may be selected for use in the present invention.
  • the incinerator may be a tunnel-type incinerator, a twin-incinerator, or a single incinerator.
  • Figure 3 shows another embodiment of the present invention, wherein elements similar to those employed in the previous embodiment are represented by like numerals. Except for the use of a twin-incinerator, this embodiment is substantially similar to the previous embodiment.
  • this embodiment comprises a vessel body 10 and a twin-incinerator 21.
  • the twin-incinerator 21 has a first incinerator 22, and a second incinerator 23.
  • the first incinerator 22 has a waste inlet 221 adjacent to a conveyor belt 14.
  • the bottom end of the first incinerator 22 is provided with a bottom outlet 222 and an ash-separating device 25.
  • One side of the bottom outlet 222 is connected to the second incinerator 23 via a conveying belt 26.
  • the other end of the bottom outlet 222 is connected to an ash collector 27.
  • a bottom outlet portion 231 of the second incinerator 23 is connected to a waste residue collector 232 via a conveying belt 29.
  • the top end of the second incinerator 23 is connected to a smoke-conveying pipe 17' upstream of a catalyst converter 18.
  • containers 12 are tilted by a tilting device 15 to deliver solid wastes onto the conveyor belt 14 which in turn feeds the solid wastes into the first incinerator 22.
  • a first incineration at a high temperature of about 500°C the resulting ash and the products of incomplete combustion are separated by the ash-separating device 25.
  • the ash is collected in the ash collector 27.
  • the products of incomplete combustion are sent to the second incinerator 23 via the conveying belt 26 for a second incineration at a super-high temperature, preferably, about 1200°C.
  • the resulting waste residue is discharged from the bottom outlet portion 231 and collected in the waste residue collector 232.
  • the first incinerator 22 Since the first incinerator 22 has burnt out the wastes, which are combustible at a temperature of lower than 500°C, a reduced amount of wastes are sent to the second incinerator 23 for incineration at a super-high temperature of about 1200°C, thereby saving energy as compared to the previous embodiment which employs a single incinerator that requires high energy to maintain a super-high temperature for all amounts of wastes.
  • the incompletely combusted hydrocarbon compounds can be converted into carbon dioxide.
  • Carbon monoxide and sulfur monoxide can be converted into carbon dioxide and sulfur dioxide.
  • the incompletely combusted oxygenated nitrogen compounds can be decomposed into nitrogen dioxide.
  • Dioxime resulting from the combustion of polymeric compounds can be decomposed into carbon dioxide.
  • sulfur dioxide is formed into sulfate salts upon combination with sea-water.
  • Nitrogen dioxide is converted into nitrate salts upon reaction with sea-water
  • the resulting salts can be further converted into chloride salts upon combination with sea-water.
  • Carbon dioxide produces carbonate salts upon reaction with sea-water.
  • the wastes which are finally discharged into the sea after the post-treatment of the smoke produced upon incineration in the present invention, are not harmful to living things and organisms in the sea.
  • solid wastes can be incinerated at sea, i.e. far from land, thereby eliminating the air pollution problems encountered with the incinerator installed on land.
