BACKGROUND OF THE INVENTION Conventionally, public treatment facilities closely related to daily life, such as garbage incineration facilities, power generation facilities, water treatment facilities, and sewage treatment facilities, have been called nuisance facilities because they degrade the living environment around them. In particular, with regard to waste incineration facilities, as the amount of waste processed mainly in urban areas increases, there is a strong desire to improve their processing capacity.However, reflecting the recent land shortage, it is currently difficult to construct new facilities, and there are already The processing capacity of the ones that have been constructed has almost reached its limit.

Therefore, in addition to the present application, the inventors of the present invention have proposed the following underground treatment facility as a structure that allows the construction of the above-mentioned nuisance facilities even in urban areas and also allows effective use of above-ground areas. ing. That is, a cylindrical shell having a cylindrical shape or a polygonal shape having a hexagonal or larger plane is installed in the ground, and a processing equipment unit for waste incineration or the like is further installed inside this shell.

[Problems to be solved by the invention] Although underground treatment equipment having such a structure enables the installation of large waste incineration facilities underground, If only a waste incineration facility was built, the ground would remain bare land, and it would be difficult to say that the above ground space in the area was utilized effectively.

On the other hand, even if a garbage incineration facility is installed underground, it will be necessary to install a chimney on the ground surface to exhaust the large amount of smoke generated when garbage is burned. If things can be built, ground space can be used effectively.

[0006] The present invention was devised in view of the above-mentioned problems of the proposed configuration described above, and provides an underground waste incineration facility that can effectively utilize the above-ground space when installing underground waste incineration equipment. We aim to provide the following.

[0007]

[Means for Solving the Problems] Therefore, the underground waste incineration facility of the present invention has a cylindrical shell installed underground whose plane is circular or a polygon of hexagon or more. An underground waste incineration facility that is equipped with equipment for discharging smoke from the equipment, and has a chimney protruding above the ground for discharging smoke from the equipment, and that has an observation deck installed at a predetermined position of the chimney. This is its characteristic.

[0008]

[Operation] The technology proposed by the present inventors has made it possible to install waste incineration facilities underground, suggesting the feasibility of constructing these nuisance facilities even in urban areas. However, in urban areas, it is required to make more effective use of ground space. In particular, in the present invention, by using a chimney that must be installed above ground in a waste incineration facility as an observation deck facility, the ground space above the underground treatment facility can be effectively utilized.

[0009] Furthermore, if recreational facilities such as heated pools and amusement parks are installed on the ground surface that can utilize the processing energy generated during waste incineration, the observation deck can be combined with these facilities to create a comprehensive entertainment facility. As a result, waste treatment facilities have been able to dispel the traditional image of them as nuisance facilities.

[0010] In addition, when the groundwater level is high, there is a problem that buoyancy occurs in the underground cylindrical shell where the waste incineration equipment is installed. It is also possible to reduce this buoyancy by applying a load.

[Embodiment] FIG. 1 is a schematic diagram showing a specific embodiment of the present invention. As shown in the figure, in this embodiment, equipment for waste incineration is arranged inside a cylindrical shell 1 underground. At the same time, a chimney 2 is provided so that the equipment protrudes above the ground. Further, an observation deck 3 is provided at a predetermined position of the chimney 2, and a heated pool 4 is provided in a dome-structured room on the ground. In this embodiment, a steel cylindrical shell 1 with a diameter of 70 m and a depth of 31 m is constructed underground using the continuous wall construction method. In particular, the bottom surface is configured in a hopper shape to facilitate wastewater treatment.

[0012] Equipment for waste incineration disposed within the shell 1 includes a chimney 2 disposed at the center of the shell 1;
A garbage pit 10 is provided in a cylindrical shape around the chimney 2, and a crane graph is installed on the top side of the garbage pit 10 and rotates within the garbage pit 10 around the center of the shell 1. a hopper stage 13 having a hopper 12 which is provided in a fan shape in the garbage pit 10 and receives the garbage thrown in by the crane 11; An incinerator 14 that incinerates garbage; an ash conveyor chamber 15 that collects ash that has been incinerated in the incinerator 14 below the incinerator 14; It has a dust collector 16 for removing dust from the smoke. Furthermore, in this embodiment, the fan-shaped outer space on the opposite side of the incinerator 14, centering on the garbage pit 10, has a hierarchical structure with floorboards 26, and the top floor communicates with a roadway 17 extending from the ground. , which serves as a garbage truck platform 19 for throwing garbage into the garbage pit 10 from the garbage truck 18 that passes through this and enters. In addition, a central control room 20 is provided on the lower floor for operating the crane 11 in the garbage pit 10, managing the combustion status of the incinerator 14, and controlling other garbage incineration facility equipment. 21 installed blower room and air transport device 2
Two air transport chambers are provided.

The chimney 2 has a multi-layer structure consisting of an inner cylinder 23 and an outer cylinder 24, and the inside of the inner cylinder 23 is a passage for smoke from the incineration equipment, and the intermediate part between the inner cylinder 23 and the outer cylinder 24. The space is a space for elevating and lowering for movement. For this reason, it is preferable that the wall of the inner cylinder 23 has a heat-resistant structure. In addition, in this embodiment, an elevator 25 is provided as a means for elevating and lowering the elevating space.

The observation deck 3 is provided at a predetermined height of the chimney 2 as described above. It is preferable to install this at a location as high as possible in consideration of the scenery from observation deck 3, but if it is located too high, there is a possibility that the view will be blocked by smoke. Therefore, it is desirable that the installation location of the observatory 3 should be determined by fully taking into account the location conditions where the chimney 2 will be installed, such as the wind direction and wind strength throughout the year. Moreover, as mentioned above, the elevator 25 disposed between the inner cylinder 23 and the outer cylinder 24 of the chimney 2 allows the elevator 25 to go up and down to the observation deck 3.

The hot water pool 4 has the cylindrical shell 1
The dome structure 27 has the same diameter as the dome structure 27 and protrudes above it. Further, the hot water in the hot water pool 4 is generated using boiler exhaust heat generated in the underground waste incineration facility, and is configured to effectively utilize energy.

According to the present embodiment described above, it becomes possible to install a waste incineration facility underground, which was considered difficult to construct in urban areas, and by providing an observation deck above the chimney, it is possible to install the waste incineration facility underground. However, the chimney, which had to be installed above ground, can be used effectively, and the above-ground space above the underground equipment can be used effectively. In addition, there is a heated pool on the ground that uses waste heat from the underground boiler, which not only makes effective use of energy, but also functions as an entertainment facility with the heated pool and observation deck. This will help dispel the image that treatment facilities are seen as nuisance facilities.
