Description

Description: TECHNICAL FIELD The present invention relates to a structure for treating waste, which is used as an intermediate treatment facility for general waste and whose outer shell is a floating structure having a box-shaped barge structure.

[Problems to be Solved by the Invention]

Conventionally, general waste is incinerated at a cleaning plant for intermediate treatment. However, the amount of general waste generated in cities and the like has increased rapidly in recent years, and the problem of waste disposal has become more serious.

Given the land and environmental problems that cities currently have, it is extremely difficult to construct a new intermediate treatment facility for incineration of waste inland.

The present invention has been made in view of the above problems.
The purpose is to propose a structure for waste treatment that does not require inland land, does not adversely affect the surrounding environment, can be moved and diverted, and can suppress inertial force and prevent damage in the event of a large earthquake. There is.

[Means for solving the problem]

In this waste treatment structure, the outer shell has a floating structure,
It is equipped with a water ballast adjustment means for floating the bottom to the bottom of the water and a waste incinerator, and the foundation bottom slab is attached to the lower surface of the bottom of the outer shell to form a double structure. It is characterized by comprising a sliding seismic isolation mechanism between.

〔Example〕

Hereinafter, description will be made with reference to the illustrated embodiment. 1 and 2 show a waste treatment structure 3 fixed and installed on the seabed 2 of the shallow sea area 1 of the inland sea. In this structure, the outer shell 4 has a rectangular parallelepiped shape to form a floating structure. The bottom and sides of the outer shell 4 are occupied by a water ballast tank 5 which is divided into a number of spaces, and a bottom plate 6 is attached to the lower surface of the bottom to form a double structure. The foundation bottom slab 6 is integrated with the outer shell 4 and is towed and sunk. However, after the ground contact with the seabed such as soft ground, a sliding seismic isolation mechanism is formed between the base and the bottom surface of the outer shell 4.

The inside of the outer shell 4 is divided into a garbage container pit 7, a garbage pit 8, an incinerator pit 9, an ash pit 10 and a dust collecting pit 11. A gantry crane 12 and a container entrance 13 are located on the terminal above the garbage container pit 7.
Is provided, and a chimney 14 projects above the dust collection space 11.

Crane 15 and crane operation room above the garbage pit 8.
There is 16 and a hopper 17 communicating with the incineration pit 9 is open. Incineration pit 9, ash pit 10 and dust collection pit 11
3 incinerators 18, an ash remover 19 and a dust collector 20 are arranged in series, respectively, and the tip of the incinerator 18 is a chimney 14
Is in communication with.

The outer shell 4 of this structure is made of concrete (PC, RC structure) or steel, the inside has a height of four times, and the roof 21 has a steel frame structure. Although not shown, a water pump is provided so that the ballast water can be adjusted to float and sink freely, and the balance of the outer shell 4 and the ground pressure can be adjusted by finely adjusting the ballast water. In addition, it is equipped with a turbine generator and a desalination device that utilize the heat of incineration of garbage, and is capable of self-sufficiently supplying the required power, industrial water or hot water. Since the height of the chimney 14 may be limited when the structure is installed near the airfield, the chimney 14 may be of a slide type or a detachable type in which the height can be freely changed.

[Work]

This waste treatment structure has the above structure. The outer shell of this structure has a floating structure and has means for adjusting the amount of ballast water, so after construction, it was towed to the desired sea area and injected with ballast water to have a bottoming, installation and incineration function. It can be operated as a facility for intermediate treatment of waste. At this time, the buoyancy is controlled by the ballast water so that the bottom of the sea is softly settled, so that it is possible to settle and install on the bottom of the sea where foundation work is not performed. In addition, the ballast water can be discharged, re-floated, moved to the installation position, or disassembled and removed at the destination. The position of the center of gravity can be freely controlled by adjusting the ballast water as necessary when towing or when the tide level changes during operation.

A base plate is attached to the bottom of the outer shell to form a double structure.
Since the sliding seismic isolation mechanism is configured, the inertia during a large earthquake can be controlled below a certain value, and damage due to the inertia can be prevented.

In order to dispose of waste with this structure, as shown in FIG. 1, the trash or trash container 23 transported by sea on a small vessel or trash container vessel 22 is unloaded on the terminal by the gantry crane 12, and the trash pit 8 or It is carried to the garbage container pit 7.

The trash carried in is incinerated in the incinerator 18 and the ash removal device
Combustion gas from which ash has been removed at 19 and dust has been removed at the dust collector 20 is emitted from the chimney 14. Residues such as ash are transported to the final disposal site for disposal.

Normally, rubber or garbage containers are transported by land to the final disposal site by truck, cross the pier, etc., to the processing structure installed in the nearby sea area, and the incineration residue follows the course in reverse, and the final disposal site. Carry to and dispose of.

〔The invention's effect〕

 This waste treatment structure has the following effects.

An intermediate treatment facility can be easily constructed without being bound by land and environmental problems.

It can be towed, sunk, settled and operated on the seabed of any sea area without a special foundation, and this can be repeated. When it is no longer needed, it can be moved and dismantled and removed outside the site.

When a large earthquake occurs, the sliding seismic isolation mechanism at the bottom of the outer shell works to keep the inertial force below a certain value and prevent major damage.

 Since it can be built in the dock, the construction period can be shortened.

Since it can be installed softly on the bottom, there is no shaking in the floating structure and it can operate even in storms.

Since it can be installed in the sea area near the final disposal site, it mainly contributes to sea transportation, reduces land transportation, and contributes to alleviation of road traffic congestion. At the same time, transportation of the residue after intermediate treatment to the final disposal site becomes very easy.

The balance and ground pressure of the structure can be adjusted with ballast water for soft landing, and there is no need for large-scale foundation work for the landing ground.

As in the embodiment, if a closed system that is provided with a generator and a desalination device that uses waste heat and is capable of self-sufficient energy such as electricity, measurement, air conditioning, and water supply and discharge equipment, it does not consider the receipt of electricity and water. You can select and install a free sea area.

In addition to the garbage disposal function, public facilities such as a seawater heated water pool that uses incineration and waste heat, a fish farm, a tropical botanical garden or crematorium, an aquarium, and a parking lot can be installed as an auxiliary facility. The facility can be highly active as a leisure facility.
