Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a waste treatment structure comprising a floating structure whose outer shell is a box-shaped barge structure, which is used as an intermediate treatment facility for general waste.

[Problem to be solved by the invention]

Traditionally, general waste has been incinerated at incineration plants for intermediate treatment. However, the amount of general waste generated in cities has increased rapidly in recent years, and the problem of garbage disposal has become more serious.

Given the land and environmental problems that cities are currently facing, it is extremely difficult to construct new intermediate treatment facilities for waste incineration in inland areas of cities.

This invention has been made in view of the above-mentioned problems. The purpose is to propose a waste disposal structure that does not require inland land, does not have a negative impact on the surrounding environment, and can be moved and repurposed.

[Means to solve the problem]

This waste treatment structure is characterized in that the outer shell has a floating structure and is equipped with water ballast adjustment means for landing on the bottom of the water and making it float, and a waste incineration device.

〔Example〕

The following will explain the embodiments shown in the drawings. Figure 1.2 shows a waste disposal structure 3 that is anchored and installed on the seabed 2 in a shallow area 1 of an inland sea. This structure has a floating structure with an outer shell 4 having a rectangular parallelepiped shape.

The bottom and sides of the outer shell 4 are occupied by a water ballast tank 5 partitioned into many spaces, and a foundation bottom plate 6 is provided on the lower surface of the bottom.
is the installation.

Inside the outer shell 4 are a garbage container pit 7, a garbage pit 8,
Incineration pit 9, ash pit 10. It is divided into 11 dust collection pits. Further, a gantry crane 12 and a container port 13 are provided on the terminal above the garbage container pit 7, and a chimney 14 protrudes above the dust collection space 11.

A crane 15 and a crane operation room 16 are located in the upper part of the garbage bit 8, and a hopper 17 communicating with the incineration pit 9 is opened. In the incineration pit 9, ash pit 10, and dust collection pit 11, three incinerators 18, an ash removal device 19, and a dust collector 20 are arranged in series, respectively, and the tips thereof communicate with the chimney 14. There is.

The outer shell 4 of this structure is concrete IJ-T (PC).

It is made of RC structure (RC structure) or steel, the interior is four stories high, and the roof 21 is a steel structure.

Although not shown, it is equipped with a water pump to adjust the ballast water to float and sink freely, and the balance of the outer shell 4 and the ground pressure can also be adjusted by finely adjusting the ballast water. It is also equipped with a turbine generator and desalination equipment that utilizes waste incineration heat, making it self-sufficient in the necessary electricity, industrial water, or hot water.

The foundation bottom slab 6 is integrated with the outer shell 4 and is towed and submerged, but after touching down on the undersea ground such as soft ground, it functions as a structure with a sliding seismic isolation mechanism between it and the bottom of the outer shell 4. Chimney 14
If this structure is installed near an airfield, there may be height restrictions, so a sliding or removable structure that allows the height to be freely changed may be used.

[For production]

This waste disposal structure has the above structure. The outer shell of this structure has a floating structure and has a means to adjust the amount of ballast water, so after construction, it can be towed to the desired sea area,
It can be operated as an intermediate waste treatment facility with the functions of landing on the bottom, installation, and incineration by injecting ballast water.
In addition, the ballast water can be discharged and resurfaced, and the installation can be relocated or disassembled and removed at the new location. When towing
Alternatively, the position of the center of gravity can be freely controlled by adjusting the ballast water as necessary when the tide level changes during operation.

To process waste with this structure, as shown in Figure 1,
Garbage or garbage containers 23 transported by sea on a small boat or garbage container ship 22 are transported by a gantry crane 12.
The waste is unloaded onto the terminal and transported to the garbage pit 8 or garbage container pit 7.

The carried garbage is incinerated in an incinerator 18, ash is removed by an ash removal device 19, and dust is removed by a gravity collector 20. Combustion gas is released from a chimney 14. Residues such as ash are transported to the final disposal site and disposed of.

Normally, trash or trash containers are transported by truck overland to the final disposal site, crossed over a pier or the like to a treatment structure installed in the nearby sea, and the incineration residue reverses its course and is transported to the final disposal site. to be disposed of.

〔Effect of the invention〕

This waste treatment structure has the following effects.

■ Intermediate treatment facilities can be easily constructed without being restricted by land or environmental issues.

■ It can be repeatedly towed, submerged, and operated in any sea area, and when it is no longer needed, it can be moved and dismantled off-site.

■ Construction time can be shortened as construction can be done inside the dock.

■ Because it can be installed with soft contact with the bottom, there is no shaking compared to floating structures, and it can be operated even in stormy weather.The ground pressure is low, so the structure can avoid sliding and large inertia in the event of a major earthquake.

■ Since it can be installed in the ocean near the final disposal site, it can contribute to alleviating road traffic congestion by relying primarily on sea transport and reducing land transport. At the same time, it becomes very easy to transport the residue after intermediate treatment to the final disposal site.

■ The balance and ground pressure of the structure can be adjusted with parast 4° water, eliminating the need for large-scale foundation work on the ground.

In addition, as in the example, if a generator and desalination equipment that utilizes waste heat is installed to create a closed system that can self-sufficient energy such as electricity, measurement, air conditioning, supply and exhaust equipment, etc., electricity,
You can freely choose any sea area and install it without considering the availability of water.

If the foundation bottom slab has a double structure with a sliding base isolation mechanism, it is possible to suppress the inertia force to a certain value or less in the event of a major earthquake, preventing major damage, and is suitable for -layers.

In addition to the garbage disposal function, there is also a heated seawater pool that uses waste heat from incineration as an auxiliary facility.

Fish farms, tropical botanical gardens or crematoriums, aquariums.

It is possible to provide public facilities such as a parking lot, and it can also be highly utilized as a waterfront leisure facility.
