Description

  The present invention relates to a waste treatment apparatus and a waste treatment method for treating waste using an incinerator or the like. In particular, the present invention relates to a waste treatment apparatus and a waste treatment method capable of operation management centering on a central control room for all processes of waste treatment.

  Conventionally, combustible waste, such as municipal waste and sewage sludge, is collected from business establishments and households, and transported to waste treatment plants and waste treatment facilities provided in each region for combustion treatment. It is taken out as exhaust gas and incinerated ash that have been cleaned. In addition, solid components such as combustion ash are rendered harmless and then used as landfill processing or building materials, and the heat generated by the combustion processing is used as a heat source for boilers and residual heat use. At this time, the transported waste (garbage) is once brought into the waste receiving space at the waste disposal site or the waste disposal facility, and is incinerated from the waste pit (garbage storage space) to the incinerator, gas cooling equipment and exhaust gas. It is transferred through the treatment facility and converted into clean exhaust gas, final disposal material (ash etc.), valuable resources (energy etc.), etc. (garbage disposal space).

  Specifically, a waste disposal facility as shown in FIGS. 4A to 4C has been proposed (see, for example, Patent Document 1). Here, FIG. 4 (A) shows a side view of the waste pit of the waste treatment facility according to the embodiment of the present invention, and FIG. 4 (B) is a side view showing the overall configuration of the waste treatment facility, FIG. (C) shows the AA arrow line view. The garbage pit 102 is separated by a garbage pit front part 102a for entering the garbage, and a garbage pit front part 102a and a partition wall 101 for transferring and storing the garbage thrown into the garbage pit front part 102a. The incinerator includes an incinerator 123 that is disposed below the waste hopper 127 and incinerates the waste introduced from the hopper 127, and combustion that combusts the waste. A boiler 124 that generates steam using exhaust gas and an exhaust gas treatment device 125 that removes harmful components in the combustion exhaust gas that has passed through the boiler 124 are provided. These various facilities of the waste treatment facility are arranged in the same building 126 (paragraph 0003). The garbage truck 104 throws the garbage 106 from the garbage throwing stage 121 into the garbage pit front part 102a. The garbage 106 is immediately transferred to the rear stage 102b of the garbage pit by the club 108 suspended from the overhead crane 107 and deposited there. Garbage 106 in the rear stage 102b of the garbage pit is put into the inlet 127a of the hopper 127 and incinerated. With such a configuration, the dust 106 brought into the rear stage 102b of the waste pit can be accumulated up to the height of the inlet 127a, so that the bottom surface of the waste pit 102 can be made shallow (summary). Here, reference numeral 103 indicated by an arrow indicates the movement of the garbage 106, and 109a indicates the bottom surface of the garbage pit.

However, there were some problems and requests in the conventional waste disposal facility.
(I) As described above, the conventional waste treatment facility is arranged in a straight line from the waste receiving space to the waste treatment space through the waste storage space. It is difficult and requires a large number of operators, and it is practically limited to a specific direction or local monitoring using a monitoring camera or the like, and overall management that can coordinate the operation between the spaces has been a problem. In particular, for safe and secure facility operation, it is important for platform supervisors, garbage crane operators, and central control room operators to operate in an efficient manner. There was a strong demand for the system.
(Ii) In addition, while the quantity and quality of waste to be transported vary greatly, in recent years there has been a demand for the establishment of a larger waste storage space as one of the measures to strengthen waste treatment facilities. In addition, in a waste disposal facility arranged in a straight line, the installation of a large waste storage space requires a means for transporting waste, such as a large crane, because the crane span length is long. Needs to be made. Furthermore, in order to increase the conventional storage capacity, the method of excavating the ground and expanding the storage space in the underground direction has also been adopted. However, the amount of spring water generated during excavation and the generation of residual soil during the construction of a waste treatment facility are being adopted. In terms of reducing the volume, reducing the underground space is a major issue. In addition, an increase in the waste storage space leads to an increased burden on incidental functions such as a deodorizing device.
(Iii) There are many cases where a platform is provided on the upper floors of two or more floors in order to take the effective volume of the conventional waste pits sufficiently. In this case, it is necessary to effectively use the downstairs space of the platform. This space has many cases where utilities (such as water supply / drainage facilities, compressed air or living rooms) that are not directly used for waste disposal are installed in the conventional linear arrangement. At this time, waste treatment space and utilities, etc. Piping, wiring, and the like between the two need to be installed through a garbage pit, and are separated from the garbage disposal space, so that the installation space increases. Such an increase in installation space hinders downsizing of garbage disposal facilities and efficiency of functions.
(Iv) In the waste treatment facility, a visitor passage is provided for environmental education and for the well-known and understanding of the plant facility, and it is often used as a passage for plant staff. At this time, it is necessary to secure the safety of the visitor and to consolidate the observation target areas and provide them close to each other. However, if the above-mentioned spaces are arranged in a straight line, the visitor passage will flow through the plant. It will be arranged along the direction, the visit points will be dispersed, and the necessary flow of visitors will become longer. In addition, in the conventional waste treatment facility, the area of its outer wall is large, and because of the need for an internal reinforcement structure (earthquake resistance, etc.), many materials are necessary for construction, and reducing it is an issue It was.

Therefore, the present invention has been made in view of the above situation, and its purpose is to solve some of these problems,
(A) While ensuring a predetermined space and strength such as a crane, it is possible to efficiently use the three-dimensional space while reducing the underground space of the pit, and to perform each processing operation by short-distance transfer and movement. While providing a waste treatment apparatus and a waste treatment method ,
(B) To provide a waste treatment apparatus and a waste treatment method capable of operation management centering on a central control room for all processes of waste treatment.
(C) Another object of the present invention is to realize a space layout that allows efficient processing operations while satisfying specifications required as a waste processing facility such as a visitor passage.

The waste treatment apparatus of the present invention has a platform for receiving a transport means for transporting the waste, a pit in which the transported waste is stored, stirred and mixed, and a transport means for transporting the mixed waste. A hopper into which the transferred waste is input, an incinerator in which the waste input into the hopper is incinerated, and heat exchange processing using the exhaust heat of the combustion exhaust gas discharged from the incinerator A solid state component such as ash discharged from the incinerator, the gas cooling unit, and the exhaust gas processing unit is collected.

In step (1) above, which is the starting point Waste that is transported to Oite said platform, characterized in that it is processed to circulate on the plane for the above step (1) to (7).

  According to the above configuration, by placing the incineration equipment for performing the processing adjacent to the platform, the incinerator in which the waste thrown in from the platform is incinerated, the gas cooling unit in which the exhaust heat and the like are heat exchange processed, It is possible to process waste to circulate in an exhaust gas treatment unit that performs purification treatment of combustion exhaust gas and an ash accumulation site where solid components such as discharged ash are collected, and a platform that requires operators And incineration facilities can be linked. Therefore, a waste treatment apparatus and a waste treatment method capable of efficiently using a three-dimensional space while ensuring a predetermined space and strength such as a crane and performing each treatment operation by short-distance transfer and movement. It became possible to provide. At the same time, it is possible to make the waste treatment equipment more compact by consolidating each treatment function, and it is possible to shorten the distance to the utility of each treatment function and to reduce the space.

It became possible to carry out by moving and moving. In the present invention, since the first pit and the second pit are arranged in the direction perpendicular to the span direction of the crane, it is possible to sufficiently ensure the stirring of dust in the pit without increasing the span length of the crane.

The above steps (1) to (7) are characterized in that the waste is processed so as to go around on a plane. Hereinafter, embodiments of a waste treatment apparatus and a waste treatment method according to the present invention will be described in detail with reference to the drawings.

<Example of basic configuration of waste treatment apparatus according to the present invention>
FIG. 1 shows a basic configuration example of the processing apparatus 10. Waste W is transported to the present processing apparatus (building) 10 by transport means T (for example, a truck or the like, hereinafter referred to as “truck T”), and the truck T is received by the platform 1. The conveyed waste W is thrown into the pit 2 from the truck T via the throwing unit 1a and stored. The stored waste W is stirred and mixed by a stirring means and a mixing means (not shown) and homogenized. The mixed waste W in the pit 2 is collected by a transfer means 3 (for example, a crane or the like, hereinafter referred to as “crane 3”) and put into the hopper 4. At this time, the crane 3 can be used as a stirring (mixing) means by repeating the collection by the crane 3, the movement in the Y direction in the figure, and the opening. The waste W put into the hopper 4 is transferred from the hopper 4 to the incinerator 5 and incinerated under high temperature combustion conditions. The combustion exhaust gas Ga containing dust (including ash) generated in the incinerator 5 is taken out from the incinerator 5 and fed to the gas cooling unit 6. The combustion exhaust heat contained in the combustion exhaust gas Ga is subjected to a heat exchange process, and the recovered heat is used as power generation or hot water by a steam turbine. The combustion exhaust gas Gb taken out from the gas cooling unit 6 is fed to the exhaust gas processing unit 7 and cleaned. The gas phase component separated and delivered in the exhaust gas treatment unit 7 is discharged from a chimney or the like (not shown). Solid components such as ash (ash) S separated and delivered in the incinerator 5, gas cooling unit 6, and exhaust gas treatment unit 7 are collected, transferred to the ash accumulation field 8 and accumulated. Such processing operations and the functions and operations of each unit are centrally monitored and managed in the control room 9.

  In the present processing apparatus 10, the hopper 4, the incinerator 5, the gas cooling unit 6, the exhaust gas processing unit 7, and the ash accumulation site 8 are arranged in an incineration facility 20, and the incineration facility 20 and the platform 1 are adjacent to each other. The incinerator 20 and the platform 1 are arranged adjacent to the pit 2. Each processing operation is performed by short-distance transfer and movement by processing the processing object from carrying in the waste W to carrying out the ash S after final processing so as to circulate in the processing apparatus 10. Can do. Further, the distance from the utility used in each operation and the space can be shortened and the apparatus can be made compact, and the processing apparatus 10 having a crane 3 and a building having a reinforced structure and a reduction in building materials can be achieved. Can be configured.

  The control room 9 is preferably installed between the platform 1 and the incineration facility 20 in the present processing apparatus 10 in order to improve functions for centrally monitoring and managing each processing operation and the function and operation of each part. It is impossible in a processing facility with a linear arrangement as before by directly monitoring and managing the operation of each part where the waste W is processed at the center of the circulation along the transfer state of the circulating waste W. It is possible to perform centralized monitoring and management. In the past, many observers were required, and even when a large number of monitor screens were installed to monitor multiple points, the individual monitoring became sparse and the overall problem was difficult to understand. The control room 9 provided in the present processing apparatus 10 enables overall centralized monitoring and can be managed while confirming the flow of processing steps.

〔pit〕
The pit 2 has a function of storing, stirring, mixing and transferring as well as a function of receiving the waste W in the present processing apparatus 10, and plays a role of pretreatment in waste processing. In particular, by homogenizing the waste W by stirring and mixing, the combustion conditions of the waste W in the incinerator 5 can be stabilized. At this time, as the agitation and mixing means of the stored waste W, a transfer means capable of repeatedly collecting, moving, and opening the waste is preferable. For example, collection and movement of a small amount to a large amount are possible. By using the crane 3, the homogeneity of the waste W before being put into the incinerator 5 can be ensured. In addition, the configuration in which the pit 2 is adjacent in the same plane as the platform 1 and the incineration facility 20 can form a long shape in the Y direction in the figure, and the crane 3 moving in the pit 2 can be moved in the longitudinal direction (Y direction). ) Can be moved greatly. Therefore, even if the volume is the same, it is possible to use the crane 3 having a smaller span length than before, ensuring a predetermined space, and at the same time, increasing the structural rigidity and ensuring sufficient strength. The building structure can be made. Further, even when the agitation operation or the mixing operation is performed by the crane 3, the length of the garbage pit in the span direction (Ys direction in the figure) with respect to the opening width of the bucket of the crane 3 can be sufficiently secured. Therefore, the homogeneity of the waste W in the pit 2 can be ensured.

  In recent years, in order to increase the storage capacity of pits and ensure stable operation of incineration facilities, underground spaces in pits are often deeper than before, but the installation of such underground spaces leads to a longer construction period. At the same time, downsizing of the apparatus is hindered. Furthermore, when the projected area of the pit is increased in order to increase the storage capacity, measures such as increasing the span length of the crane are required, and the crane and the building structure become excessive. In the pit 2 of the present processing apparatus 10, the pit 2 can be formed shallower than before even with the same volume while keeping the span length of the crane 3 short, so that the operation rate of the crane 3 is lowered. And power consumption can be reduced. In addition, a sufficient storage capacity, minimization of underground space, and an appropriate building structure can be ensured.

  In addition, the reduction of the underground space in pit 2 reduces the amount of residual soil generated, the number of construction vehicles, or the amount of spring water generated during excavation (the amount of drainage) during construction of this treatment apparatus 10 to the groundwater level. And the like can be reduced. Furthermore, in order to carry out construction work efficiently, it is necessary to have a facility layout in which steel structures and reinforced concrete (RC) structures that are usually used in incineration treatment equipment are integrated. In the present processing apparatus 10, the platform 1 and the combustion facility 20 are steel structures, and the pit 2 is RC structures, so that the steel structure sections and RC structure sections can be consolidated, and the efficiency of construction work can be improved. With the conventional arrangement of each part in a straight line, the steel structure platform 1 and the combustion facility 20 are arranged with the RC pit 2 interposed therebetween, and it is difficult to speed up the construction. Similarly, in the case of dismantling the facility, the range to be backfilled is small, and the disassembly work period, the amount of waste materials generated or the cost can be reduced. Furthermore, in this processing apparatus 10, since planar arrangement | positioning becomes a shape close | similar to a square, the area required for the outer wall of a building becomes small, earthquake resistance improves, and it can aim at reduction of a required building material.

[When the platform is placed in the upper level]
The processing apparatus 10 has a multi-level floor as shown in FIG. 2 exemplarily showing the XX cross section in FIG. 1, and the ash accumulation field 8 is installed on the lowest floor (for example, 1F). The platform 1 is installed on the upper floor (for example, 2F) of the ash accumulation site 8, and the control room 9 for monitoring and controlling each operation is arranged in the center on the apparatus plane, and further on the upper stage of the platform 1. It can also be arranged on the floor (for example, 3F).

  In other words, by accepting the waste W, which is a raw material, and sending out the ash S, which is a discharge, by changing the hierarchy (for example, 1F and 2F), efficient three-dimensional space utilization is achieved, and each processing operation is performed. It can be done by short distance transfer and movement. Even in the previous configuration, there are many cases where the platform is set to 2F and the effective area of the pit area is sufficient, and water and drainage facilities are installed as an effective use of the 1F space below the platform due to the demand for compact waste treatment equipment. there were. That is, in the conventional linearly arranged configuration, the 1F space is separated from the waste treatment space (incineration facility 20 in the present processing apparatus 10), and therefore, it is not directly related to the treatment in order to effectively use the space. For example, utilities such as water supply and drainage facilities were installed. At this time, piping and wiring between the waste treatment space and the placement equipment under the platform must be installed through the pit area, and the increase in installation space occupied by piping and wiring as described above is a major issue It was. In the present processing apparatus 10, the platform 1 and the waste processing space are close to each other, and the installation space such as piping and wiring can be greatly reduced, and efficient operation and work can be performed during operation and maintenance. It can be carried out.

  In addition, by providing the control room 9 in the upper level (for example, 3F) in the center, operation management centering on the control room 9 can be performed for all processes of waste treatment, and at the same level as the control room 9 or lower. By providing a visitor passage and a visitor space 11 in the upper hierarchy, the entire processing apparatus 10 can be visited. Previously, the platform monitor, crane operator, central control room operator, monitor, etc. (hereinafter referred to as “operators”) were individually arranged. For safe and secure facility operation, however, It is important for workers to drive with efficient cooperation. In the conventional linear arrangement, as described above, it cannot be arranged close to each other. However, in the case of the present processing apparatus 10, the operators are arranged in a concentrated manner in the control room 10, and the operators are in close contact with each other. Cooperation becomes possible, and access to the platform 1 and the incineration facility 20 is facilitated, thereby improving workability. In addition, the platform 1 and the incineration facility 20 that could not be directly monitored in the past can be simultaneously monitored from the control room 9, so that the safety in the platform 1 is improved and the emergency response is quickly performed by a plurality of people. As a result, the distance of the daily inspection inspection line is shortened and workability is improved. In addition, as mentioned above, the visitor passage used as the operator's passage is provided for environmental education, etc., ensuring the safety of the visitor and consolidating the visit area. It is necessary to provide it. In the conventional linear arrangement, the visitor passage is arranged along the flow direction of the plant, and the visit points are dispersed. However, in the case of the present processing apparatus 10, waste in the visitor space 11 is disposed. From the reception of W to the processing operation and discharge can be intensively observed. Accordingly, the necessary flow line for the visitor is shortened and the safety of the visitor is improved.

<Second Configuration Example of the Processing Apparatus>
3A and 3B show a second configuration example of the processing apparatus. The basic configuration is the same as that of the first configuration example, but in the present processing apparatus 10a, the pit 2 is agitated and mixed with the first pit 2a in which the transported waste W is stored. And the partition wall 2c is provided in the middle, the platform 1 is adjacent to the first pit 2a, and the incineration facility 20 is adjacent to the second pit 2b. FIG. 3A illustrates a plan view of the processing apparatus 10a, and FIG. 3B illustrates an elevation of the ZZ cross section thereof. Here, the dust processing apparatus 7a is illustrated as a processing unit having a gas-solid separation function in the exhaust gas processing unit 7.

  The pit 2 is divided into a section that receives the waste W (first pit 2a) and a section that stores the waste W that has been transferred and stirred (second pit 2b). By dividing the pit 2 into two sections, the upper space of the pit 2 is effectively utilized for storing the waste W, and the function of receiving the waste W and stirring (pretreatment for transfer to the hopper 4) is different. Dedicated and efficient operations can be performed. In addition, the processing apparatus 10a has a partition wall between the first pit 2a and the second pit 2b in response to the installation of an underground space accompanying an increase in the storage capacity of the pit 2 and the expansion of the span length of the crane 3. By providing 2c up to the stage level of the hopper 4, the underground space can be minimized, and the received waste W can be separated along the flow direction of the partition wall 2c without increasing the span length of the crane 3. The waste W stirred in the second pit 2b can be stored in a large volume via the.

  In addition, the platform 1 is adjacent to the first pit 2a, the incineration facility 20 is adjacent to the second pit 2b, and not only the second pit 2b for storage but also the first pit 2a for receiving are cranes in the crane span direction. Even if the opening width has a sufficient length for mixing and mixing of waste, it is excellent in stirring and mixing performance of garbage more than before, and even if the variation in the quantity and quality of waste W conveyed is large The quality and quantity of waste transferred to the incineration facility can be adjusted appropriately. Therefore, it is possible to efficiently use the three-dimensional space while reducing the underground space of the pit 2 and to perform each processing operation by short-distance transfer and movement.

  Here, the crane 3 has at least a first crane 3a for transferring the waste W from the first pit 2a to the second pit 2b and a second crane 3b for transferring the waste W from the second pit 2b to the hopper 4. You can also. Further, by operating both of them independently, the first crane 3a has a stirring function when it is put into the second pit 2b simultaneously with the transfer function of the waste W, and the second crane 3b has the second pit 2b. The waste W in the second pit 2b can be stirred and mixed at the same time as it has a stirring function when transferring the waste W in the hopper 4.

<Waste treatment method according to the present invention>
The processing method includes (1) a receiving means receiving step, (2) waste storage, stirring and mixing step, (3) hopper charging step, (4) incineration processing step, and (5) gas cooling. A heat exchange treatment process in the section, (6) a purification process of combustion exhaust gas, and (7) a solid component collection process such as ash, etc., and using waste as a raw material in the above-mentioned process (1) The processing units according to the steps (4) to (7) for performing the processing are arranged adjacent to the processing unit according to the step (1), and the steps (1) to (7) are planar with respect to the waste W. It is processed so that it may go around.

  The platform 1 that receives the waste W is disposed adjacent to the incineration facility 20, and the waste W (the ash content S after the incineration process) is processed so as to go around the plane, thereby reducing the span length of the crane 3 and the like. While ensuring a predetermined space and strength without expanding, it is possible to efficiently use a three-dimensional space, and to perform each processing operation by a short-distance transfer and movement. Specifically, each process will be outlined based on a case where a processing operation is performed using the configuration example of the processing apparatus 10 described above.

(1) Receiving Step of Conveying Means (Waste) The conveying means (truck) T for conveying the waste W is received by the platform 1, and the waste W becomes a processing object of the processing apparatus 10. At this time, it is preferable to know in advance the amount and type of waste W received (separated plastic, paper, sewage sludge, etc.) and its properties (presence of pulverization, etc.). Efficient processing in the subsequent stage can be estimated.

(2) Waste storage, agitation, and mixing step The transported waste W is put into the pit 2 from the loading platform of the truck T and stored. Meanwhile, it is stirred and mixed by stirring (mixing) means. When the transfer means (crane) 3 is used as a stirring (mixing) means, it is preferable to transfer the mixed waste W to a position in the pit 2 close to the hopper 4 simultaneously with the stirring and mixing process. By increasing the uniformity of a predetermined amount of waste W as a lot unit, efficient processing in the subsequent stage can be performed. Further, as the pit 2, the first pit 2 a adjacent to the platform 1 and the second pit 2 b adjacent to the incineration facility 20 can be used to independently perform the storage process and the agitation and mixing process. Both the 1 pit 2a and the 2nd pit 2b have a crane opening width in the span direction of the crane 3 that is long enough to agitate and mix the waste. Even when the amount and quality of the material W vary greatly, the quality and amount of the waste transferred to the incineration facility can be adjusted appropriately.

(3) Hopper throwing step The mixed waste W is transferred from the pit 2 by the crane 3 and thrown into the hopper 4. At this time, it is preferable to monitor the property of the waste W while managing the input amount of the waste W to be input. For example, by calculating the “bulk specific gravity” from the volume and weight of the waste W to be input, or by grasping the presence / absence of differences in the shape distribution of individual substances and the properties of the receiving state based on the image data of the waste W, The amount of heat generated in the combustion furnace 5 can be predicted.

(4) Incineration process The waste W thrown into the hopper 4 is incinerated in the incinerator 5. At this time, by grasping changes in the calorific value, the ash emission amount or the exhaust gas amount based on the difference in the processing amount and properties of the waste W, and performing control using these as an index, the incinerator 5 Incineration can be performed under optimal combustion conditions.

(5) Heat exchange treatment process in the gas cooling section The combustion exhaust gas Ga including the exhaust heat discharged from the incinerator 5 is heat exchange treated in the gas cooling section 6, and the recovered heat is used for power generation by the steam turbine or hot water. It can be used as a valuable resource.

(6) Combustion exhaust gas purification process The combustion exhaust gas Gb discharged from the gas cooling unit 6 is purified by the exhaust gas processing unit 7. Specifically, a detoxification process such as a neutralization process is performed, and a gas-solid separation process is further performed by a dust removal process. The gas phase component separated and delivered is discharged from a chimney or the like (not shown).

(7) Ash and other solid component collection process Solid components S such as ash generated and separated in the incinerator 5, gas cooling unit 6 and exhaust gas treatment unit 7 are collected in the ash accumulation field 8, loaded onto the truck T, and transported off-site. Is done.
