[0002]

2. Description of the Related Art Heretofore, facilities such as incineration facilities and melting processing facilities, mainly processing furnaces with a combustion process, have been arranged in a plane on a large site such as an incineration plant. For this reason,
In view of the fact that land shortages have become severe and that the aesthetic problems of the urban area cannot be ignored, underground large cavities and chimney pits following the underground large cavities are excavated in the mountains, and incinerated in the underground large cavities. It has been proposed to provide a treatment plant (for example, see Japanese Patent Application Laid-Open No. Hei 7-116627).

[0003]

SUMMARY OF THE INVENTION In the above proposal,
The conventional incineration equipment is to be relocated to the mountain basement as it is, and no proposal has been made for changing the equipment arrangement due to the underground equipment.

However, there remains a problem from the viewpoint of maintenance of the processing furnace and the exhaust gas treatment devices arranged vertically in the space above the processing furnace. In other words, for example, in order to perform maintenance work on the lower part of the auxiliary equipment arranged vertically, the vertical space of each of the auxiliary equipment is required, and in particular, the underground space has a flat sectional area. Otherwise, to remove from the underground space to replace or overhaul the equipment located below, before removing the target equipment,
It is necessary to take out all the equipment arranged above from the underground space. Therefore, the waste disposal equipment of the present invention solves the above-described problems, and is disposed in an underground space formed above and below. The purpose is to provide a material processing facility.

[0004]

[Means for Solving the Problems] The first feature of the waste treatment equipment of the present invention for the above purpose is as described in claim 1 for a treatment furnace and associated equipment.

In addition, the second characteristic configuration of the waste treatment equipment of the present invention for the above-mentioned object is that, as described in claim 2, a maintenance space for the treatment furnace and its associated equipment is provided along the equipment space, The point is that communication is formed. In addition, as described in claim 3, it is even better if a moving space capable of moving the auxiliary equipment to the maintenance space is formed between the equipment space and the maintenance space (third characteristic configuration), An exhaust gas treatment facility (fourth characteristic configuration) for purifying exhaust gas from the treatment furnace as described in claim 4, as an auxiliary facility disposed in the facility space, or a power generation facility ( It is effective if the (fifth characteristic configuration) is provided.

According to the above-mentioned first feature configuration, maintenance and repair work is easy even when the auxiliary facilities are densely arranged in the facility space, that is, in the underground space. Can be done. That is, the equipment in the equipment space can carry in or out the equipment itself or the repair parts to and from the maintenance place through the communicating maintenance space, so that other equipment can be prevented from obstructing the maintenance and repair. According to the second characteristic configuration, the maintenance and repair work can be easily performed in the vertically disposed equipment space, that is, the waste treatment equipment vertically arranged in the underground space. That is, since the maintenance space is provided along the equipment space, if a communication passage is provided between the equipment space and the maintenance space,
Workers can enter and exit the equipment space through the maintenance space, and the arrangement of other accompanying equipment does not hinder the work. In addition, since the parts having a size that can pass through the communication passage can be transported through the maintenance space, each auxiliary facility or its parts can be easily replaced. According to the third feature configuration,
In each of the above-described features, the replacement of the associated equipment itself can be easily performed. In other words, even if other auxiliary equipment is provided on the outlet side of the equipment space of the auxiliary equipment that needs replacement, when taking out the auxiliary equipment to be replaced from the equipment space,
If the inside of the maintenance space is lifted up after moving to the maintenance space through the moving space, the equipment at the equipment space outlet side will not be in the way. This is the same when charging. In addition, even when other auxiliary equipment is provided in the vicinity of the auxiliary equipment to be maintained, the other auxiliary equipment is temporarily evacuated to the moving space, so that the maintenance target auxiliary equipment can be maintained without any trouble. It is also possible to secure space. When an exhaust gas treatment facility is provided in the facility space as in the fourth characteristic configuration, the exhaust gas treatment facility requires frequent cleaning and component replacement.
Each of the above features is extremely effective. Further, even when a power generation facility is provided in the facility space as in the fifth feature configuration, the above-described features are extremely effective for periodic inspection, overhaul of turbine equipment, and the like. as a result,
While it is possible to provide the processing furnace, the auxiliary equipment, and each auxiliary equipment in the underground space in close proximity, maintenance and repair of the processing furnace and each auxiliary equipment become easy.

The dust can be directly input to the dust hopper 1a through the hopper 6, and a conventional dust crane is unnecessary. In order to drain garbage, the garbage pit 16 is provided with a pit water drainage channel 16c that discharges water to the side and guides the water downward. The pit water collected at the lower part of the pit water drainage path 16c may be sprayed into the incinerator 1 and subjected to deodorization purification treatment.

When the dust removing device 9 is formed as a bag filter device 9A, the bag filter device 9A is provided with brackets 9b on all four sides so that the upper structure 9a can be supported by the support mechanism 13. The gas discharge part 22 which discharges the exhaust gas after dust removal from the upper part is good.
The upper structure 9 is configured to discharge the exhaust gas upward, and is constituted by a rotating bed 9 d having an opening at the center of the bottom and forming a gas introduction unit 21 for introducing the exhaust gas.
It is sufficient that a support for the bag filter 9c is attached to a (see FIG. 3). A back-and-back mechanism 17b for moving the back-wash nozzle 17a to and from the bag filter 9c and a back-wash mechanism 17 such as a back-wash air supply mechanism 17e, that is, the auxiliary machine 7 are disposed beside the bag filter device 9A.

Is melted. In this case, even if the exhaust gas flows into the dust collecting duct 19, the exhaust gas circulates and returns to the incinerator 1, and convection occurs, so that dust is not blown up in the dust collecting duct 19. Since the accessory storage space S is provided as described above, the support mechanism 13 supports the bag filter device 9A.
Since the auxiliary device 7 is installed on the ground in the auxiliary device accommodation space S, the auxiliary device 7 is stably supported, and the support mechanism 13 of the bag filter device 9A is particularly large. You don't have to.

Next, another embodiment of the present invention will be described. <1> In the above-described embodiment, an example has been described in which the exhaust gas treatment device 5 is provided in the equipment space A1 from the lower position to the higher position in order from the lower position in accordance with the processing sequence of the exhaust gas. However, the arrangement order of the exhaust gas treatment device 5 may be different from this.

<2> In the above embodiment, an example was described in which the exhaust gas cleaning device 10 was provided with the catalytic denitration device 10A. However, the exhaust gas cleaning device 10 was constituted by a wet exhaust gas treatment device 10B. You may. For example,
As shown in FIG. 5, as described in the above embodiment,

It is more preferable that a circulating water cooling mechanism be provided at the outlet a side.

<3> In the above embodiment, the housing space A is formed by providing a box-shaped space peripheral wall portion 11 in a shaft excavated from the ground, and is partitioned by a partition wall 12 composed of a vertical wall. Thus, two partition spaces B are formed to form an equipment space A1 and a maintenance space A2. The partition wall 12 is provided with an opening 12a to provide the equipment space A1 and the maintenance space A.
2 has been described, but the accommodation space A may be formed in a cylindrical space peripheral wall portion 11 buried in a shaft, and the peripheral wall portion 11 has a cylindrical shape. If it is, the strength of the surrounding ground against the earth pressure increases, so that even if it is thin, it sufficiently functions as a peripheral wall. Further, the housing space A may be partitioned by a vertical partition wall 12 and divided into a plurality of partition spaces B in the circumferential direction.

Further, the housing space A is provided with a cylindrical shell inside the cylindrical space peripheral wall portion 11, and the housing space A is vertically disposed between the shell and the space peripheral wall portion 11 outside the shell.
May be divided into a plurality of partition spaces B. For example, as shown in FIG. Six vertical partition walls 12 are provided to divide the accommodation space A into six, and are divided into a partition space B including three equipment spaces A1 and three maintenance spaces A2. It is also possible to select an equipment arrangement in which the equipment space A1 in which the auxiliary equipment 3 is arranged is different from the equipment space A1 in which the auxiliary equipment 3 located below is arranged. According to such equipment arrangement, even if the accessory equipment is arranged in the same equipment space A1 with a narrow vertical space, the equipment can be moved to and from the ground through the adjacent maintenance space A2. Thus, the accommodation space A can be formed by a shallow shaft as a whole. In addition, as a procedure for moving the equipment, when extracting the equipment disposed below from the ground, the equipment located above the equipment is evacuated to the maintenance space A2, and the equipment is lifted from above the equipment space A1. You may. By doing so, the maintenance space A2 only needs to secure a space for retracting the equipment. Therefore, the inner diameter of the shaft may be small, and the strength of the ground can be used effectively.
In this case, for example, as shown in FIG. 2B, the underground beam 14 buried in the ground around the shaft or the side wall of a structure constituting the accommodation space A is fixed, and the individual exhaust gas treatment devices 5 are mounted. A support mechanism 13 for suspending and supporting may be provided.

<4> Further, the auxiliary equipment 3 may be sequentially arranged spirally in each equipment space A1 in accordance with the processing sequence of the exhaust gas, and the cylindrical shell has an elevator for inspection personnel inside. Is installed, the shell can be used as a maintenance shaft P to facilitate inspection of each associated facility 3. Further, an elevator may be provided in a partitioned space as the maintenance space A2. Further, the maintenance shaft P may be used as a maintenance space A2, and the associated equipment 3 and the parts of the processing furnace F may be formed so as to be transportable through the maintenance space A2. The equipment in A1 can be carried in and out of the elevator through the maintenance shaft P also serving as the maintenance space A2. And
All the compartment spaces B can be used as the equipment space A1, and the equipment can be effectively arranged without deepening the shaft.
In addition, maintenance becomes easy. Further, if the compartment B is a fire-prevention compartment, even if a fire occurs, it is possible to prevent at least the spread of fire or the spread of fire to another compartment B. Also, even if the harmful gas leaks in one compartment B, it can be prevented from leaking into another compartment B, which is effective in disaster prevention.

Further, the supporting mechanism 13 of each auxiliary equipment 3 is configured to be movable in the circumferential direction of the shell, and the partition wall 12 is formed with an opening 12a which can be opened and closed. It may be configured to be able to move to the defined space B. With this configuration, when the lower auxiliary equipment 3 is pulled out of the compartment space B for repair, or when the auxiliary equipment 3 to be replaced is inserted into a predetermined position in the compartment space B, it is obstructive. Can be evacuated. With such a configuration, it is possible to make the interval of the vertical arrangement height of each auxiliary equipment 3 narrower than the height of each auxiliary equipment 3, and to effectively arrange the equipment in a shallow underground space. Becomes possible. Further, even if the interval between the heights of the auxiliary facilities 3 is reduced as described above, the auxiliary facilities 3 adjacent to the upper side are not located directly above the auxiliary facilities 3 located below, so the auxiliary facilities 3 located below the lower side 3, a sufficient work space can be secured, and maintenance becomes easy.

<4> Also, as shown in FIG. 7, a moving space C communicating between the accommodating spaces A each formed of a separately excavated shaft is provided, and one accommodating space A is defined as an equipment space A1,
The other storage space A is formed as a maintenance space A2 for maintenance and inspection of the processing furnace F and the associated equipment 3, and a maintenance shaft parallel to the maintenance space A2 having an elevator for inspection personnel. It is even better if P is provided, and it is even better if the entrance is arranged in the moving space C. This elevator may be provided in the maintenance space A2. The accommodation space A may be one that vertically divides a shaft. In this case, each accommodation space A
Since the floor surface is formed every time, the maintenance work is safe. When the accommodation space A is formed by an inclined shaft, an incline or a cable car facility may be provided instead of the elevator.

<5> In the above-described embodiment, an example in which the maintenance space A2 is provided along with the single equipment space A1 has been described. However, a plurality of the equipment spaces A1 may be provided.
In addition, the maintenance space A2 is provided in the plurality of equipment spaces A1.
May also be provided. In other words, the facilities may be arranged in the accommodation space A in a one-sided manner, and the spare space may be set as the maintenance space A2. In this way, the structure of the accommodation space A can be simplified.

<6> In the above description, an example in which the storage space A is formed by a vertical shaft has been described. However, the storage space A is formed by an inclined shaft excavated underground, and is directly or indirectly supported on the ground around the inclined shaft. A supporting mechanism 13 may be provided in each of the exhaust gas treatment devices 5. That is, the accommodation space A
If the is formed of a shaft, if the facilities that can be installed using the peripheral wall of the lower inclined shaft,
If the support mechanism 13 is configured to be installed on a slope, the mechanism is simplified. If the lower surface of the shaft is excavated and leveled and the equipment is kept stationary, the support mechanism 13 will be simple, and even if a soil or side anchor is driven in or an underground beam is buried, The surrounding wall can be used. For example, as shown in FIG. 8, an equipment space A1 is formed by excavating a shaft shaft, and an adjacent shaft shaft is excavated to form a maintenance space A2 above the equipment space A1 so as to constitute the accommodation space A. In this way, a moving space C that connects the equipment space A1 and the maintenance space A2 may be formed. According to the configuration of the accommodation space A, each of the accompanying facilities 3
Can be installed on the ground of the peripheral wall portion 11 of the facility space A1, respectively, so that the structure of the support mechanism 13 of each of the accompanying facilities 3 can be simplified. In addition, since the maintenance space A2 is formed by an inclined shaft, the work can be safely performed when maintenance personnel enter and exit and when equipment is carried in and out. Further, when the maintenance space A2 is located above the equipment space A1 as shown in the figure, the carry-in device may be installed by hanging it down to install it on the support mechanism 13, so that the lateral movement is required for the installation work. And workability can be improved. If a guide rail is installed in the maintenance space A2, loading and unloading of the equipment becomes easier.
Further, since the lower part of the equipment space A1 is the ground, sufficient supporting strength can be expected, and each of the accompanying equipments 3 can be stably supported.

It is to be noted that the equipment space A1 formed in the inclined shaft is divided by the partition wall 12 and divided into two division spaces, and the division space in which the auxiliary equipment 3 located on the upper side is arranged is replaced with the auxiliary equipment located on the lower side. It is also possible to select a device arrangement different from the section space where the device 3 is arranged. For example, the accommodating space A may be partitioned by vertical partition walls 12, and the auxiliary equipment 3 may be alternately arranged in each of the laterally adjacent partitioned spaces in accordance with the processing order of the exhaust gas. In addition, each auxiliary equipment 3
The support mechanism 13 is configured to be movable in the lateral direction, and an opening 12a that can be opened and closed is formed in the partition wall 12, so that the auxiliary equipment 3 can be moved to an adjacent partition space as necessary. I just need. In this case, the maintenance space A2 may be separately provided, and one or both of the equipment spaces A1 formed in the partition space may be configured to also serve as the maintenance space A2. With such a configuration, when the auxiliary equipment 3 below is pulled out of the compartment for repair, or when the auxiliary equipment 3 to be replaced is inserted into a predetermined position in the compartment, it becomes an obstacle. Can be retracted into the adjacent compartment space. In addition, as described above, the auxiliary facility 3
Is not located close to the auxiliary equipment 3 located below, so that a sufficient working space can be secured above the auxiliary equipment located below, and maintenance becomes easy. Further, the partition wall 12 may be provided along the accommodation space A so as to vertically divide the accommodation space A formed in the inclined shaft, and may be divided into division spaces. In this case, if the upper partitioned space is the maintenance space A2, the same configuration as the above <5> can be obtained. Further, if the partition wall 12 is a fire wall, the partition space can be a fire barrier, which is effective in disaster prevention.

<7> In the above description, an example of arranging the auxiliary equipment 3 in a shaft or an inclined shaft has been described. For example, as shown in FIG. 9, an introduction shaft L formed by a shaft excavated in the ground is used as a maintenance space. As the space A2, the equipment space A1 may be formed by a plurality of subspaces E formed in a lateral direction at different heights around the periphery. Then, each auxiliary equipment 3 may be installed on the ground in the equipment space A1 formed by each subspace E. If the equipment space A1 is configured in this way,
Each auxiliary equipment 3 is a maintenance space A2 formed by the introduction pit L.
Can be carried in and out of the vehicle, and can be used as a maintenance passage.
It can also be used as a duct space for 9, etc. Moreover, as described above, since each auxiliary equipment 3 is installed on the ground in the equipment space A1, it is not necessary to increase the strength of the support mechanism 13.

<8> Also in the above <7>, the introduction pit L may be formed as an oblique shaft, and the introduction pit L is used as the maintenance space A2, and a horizontal position is set around the maintenance pit A2 at different height positions. The equipment space A1 may be formed by a plurality of subspaces E excavated and formed in the direction. Then, each auxiliary facility 3 may be installed on the ground in each sub space E. Its features are the same as in the above <7>. Moreover, access to each subspace E is easy. Further, it is also possible to install an exhaust gas duct and a dust collection duct along the introduction pit L.

<9> In the above description, an example in which the accommodation space A is formed by a shaft or a shaft is described. However, the storage space A is formed to be bent so that the shaft and the shaft or a combination of the shafts is formed. You may. Further, a configuration in which a shaft, a shaft, a horizontal hole, and the like are appropriately connected may be employed. For example, FIG.
As shown in FIG. 0 (a), an inclined shaft may be provided by branching downward from the middle of the shaft forming the maintenance space A2, and a shaft communicating with the inclined shaft may be provided below to form the equipment space A1. Further, a processing furnace F may be disposed in a lower space, a garbage pit 16 may be provided in the shaft, and each exhaust gas treatment device 5 may be disposed in a facility space A1 formed by the shaft descending from the shaft and the shaft. The equipment space A1 and the maintenance space A2
Moving space C that can carry the auxiliary equipment 3
When the maintenance or repair of each of the auxiliary facilities 3 is performed, the moving space C is used for the maintenance or repair of the associated auxiliary facilities 3.
Can be moved to the maintenance space A2 and lifted to the ground. If a dust collector provided with a heat resistant filter such as a ceramic filter is used as the dust removing device 9, it is possible to directly remove the exhaust gas from the waste heat boiler as shown in the figure. With such a configuration, the dust pit 16 may be arranged in the maintenance space A2 as shown in the figure, and it is only necessary to secure a necessary space as the maintenance space A2 on the side. Further, a plurality of inclined shafts branching from the shaft forming the maintenance space A2 may be excavated to form the equipment space A1, and in this case, the shaft immediately above the processing furnace F may be used as an exhaust pipe.
The draft can be ventilated by the heat of the processing furnace F (see FIG. 2B).

Although the figure shows a structure in which two shafts are excavated and a shaft is formed downward from each lower end, the equipment space A1 may be formed only by the shaft. In this way, it is sufficient to excavate each of the inclined shafts or the shafts connected to the shafts as necessary according to the height at which the auxiliary equipment 3 is arranged.
Drilling depth can be reduced. Further, it is also possible to branch a lower end portion of the shaft and excavate a plurality of inclined shafts, excavate the shaft below each of the inclined shafts, and connect the respective shafts. If the accommodation space A is configured in this manner, a large underground space can be secured even if the site area to be secured on the ground is small. The inclined shaft connecting the one shaft and the lower shaft may be a horizontal hole.

<10> Further, as shown in FIG. 11, the equipment space A1 may be formed by a lateral hole excavated laterally from the lower end of the shaft, and an inclined shaft is provided at a necessary position above the lateral hole. The maintenance space A2 may be provided so as to communicate with the maintenance space A2 formed by the shaft. The maintenance space A2 above the lateral hole may directly communicate with the ground. Of course, as for the auxiliary equipment 7 of each equipment in each of the above examples, if the auxiliary equipment accommodation space is provided, each equipment can be effectively arranged.
