[0046] Referring to Figures 1 to 7 , the integrated garbage incineration power plant layout structure of the present application will be described in several embodiments.

[0047] As Figures 1 to 7 shown, the integrated garbage incineration power plant layout structure of the embodiment of the present application comprises a garbage storage area 100, a sewage treatment area 200, a boiler incineration area 400, a power distribution area 510, a steam turbine power generation area 530 and a flue gas treatment area 900.

[0048] It can be understood that, as Figure 1As shown, the sewage treatment area 200, the boiler incineration area 400 and the power distribution area 510 are arranged along the edges of the garbage storage area 100, and share a wall with the garbage storage area 100. As shown in FIG. 2, the sewage treatment area 200 shares a wall with the garbage storage area 100, and does not need to be separately provided with a wall, thereby reducing the construction cost of the wall and the civil construction cost. In addition, the sewage treatment area 200 does not need to be provided with a spacing, thereby reducing the floor area.

[0049] In this way, the other functional areas surround the garbage storage area 100 according to the functional requirements, which not only meets the use requirements of the garbage incineration process, but also achieves the purpose of supporting the central area components by the surrounding area components in the structure stress, so that each component can play its role as much as possible, and the repeated components are avoided, so that the entire plant forms an organic stress whole. Compared with the conventional arrangement system, the integrated garbage incineration power plant layout structure is more reliable and safe.

[0050] It can be understood that the sewage treatment area 200 is used for treating garbage leachate. Specifically, the shared wall between the garbage storage area 100 and the sewage treatment area 200 enables the garbage leachate in the garbage storage area 100 to be connected to the sewage treatment area 200 at the shortest distance, thereby further reducing the cost. The sewage treatment area 200 recycles the garbage leachate after treatment, realizes zero discharge of the treated leachate, solves the problem of long-distance transportation of the conventional garbage leachate to the sewage treatment station, reduces the pipeline cost of the leachate, and reduces the leakage risk of the leachate.

[0051] It can be understood that the sewage treatment area 200 is arranged near the garbage storage area 100, which reduces the transportation distance of sewage, concentrated liquid, biogas and odor, saves the engineering cost, and reduces the system operation energy consumption.

[0052] It can be understood that the boiler incineration area 400 is arranged along the front long edge of the garbage storage area 100, as shown in FIG. 4. Figure 1 Specifically, the boiler incineration area 400 includes an incinerator 411, and the feeding port 420 of the incinerator 411 is arranged close to the garbage storage area 100, so that the garbage can enter the feeding port 420 of the incinerator 411 from the garbage storage area 100, thereby reducing the transportation path of the garbage, as shown in FIG. 4. Figure 2

[0053] It can be understood that the power distribution area 510 is arranged along the right short edge of the garbage storage area 100, so that the power distribution area 510 forms an additional span of the garbage storage area 100, and resists the horizontal thrust of the garbage in the garbage storage area 100.

[0054] ​It can be understood that the incinerator 411 is in communication with the waste heat boiler 840, and the flue gas generated by the waste incineration is directly input from the chamber of the incinerator 411 into the chamber of the waste heat boiler 840. The waste heat boiler 840 is used to realize heat recovery of the flue gas, so as to ensure that the temperature of the flue gas does not damage the treatment equipment of the flue gas treatment area 900. The waste heat boiler 840 comprises a steam port and a flue gas port, the steam port is used to output the steam generated by heat exchange, and the flue gas port is used to output the flue gas after heat exchange.

[0055] It can be understood that the power distribution area 510 extends along the front-rear direction, and one end close to the waste heat boiler 840 is connected with the steam turbine power generation area 530, that is, the front end of the power distribution area 510 is connected with the steam turbine power generation area 530, as shown in Figure 1 、 Figure 4 and Figure 5 , the length of the steam pipeline required for the steam communication of the two is reduced, and the heat loss of the steam in the conveying process is reduced. Specifically, the steam turbine power generation area 530 comprises a steam turbine generator, and the steam port is connected with the steam turbine generator through a short steam pipeline.

[0056] In this way, after the garbage is incinerated in the incinerator 411, the heat energy recovered by the waste heat boiler 840 converts the water into steam, and the steam is sent to the steam turbine generator of the steam turbine power generation area 530 through the steam pipeline to generate electricity, so that the steam drives the steam turbine generator to generate electric energy. The positions and functions of the power distribution area 510 and the steam turbine power generation area 530 are closely connected, the steam turbine generator provides stable power output, the power distribution area 510 ensures that the electric energy is safely and efficiently distributed to the electric equipment of each area, and the two together constitute the core framework of the power system.

[0057] It can be understood that the right end of the power distribution area 510 away from the garbage storage area 100 is provided with the flue gas treatment area 900, as shown in Figure 1 , the flue gas treatment area 900 extends along the front-rear direction, so that the long strip-shaped space is sufficient for the flue gas treatment area 900 to arrange the related equipment in a straight line according to the flue gas treatment process, so that the flue gas generated by the garbage incineration can be orderly treated, and the treated flue gas can meet the emission standard.

[0058] It can be understood that the flue gas treatment area 900 comprises a flue gas purification system 910, as shown in Figure 1 、 Figure 4 and Figure 5 , the flue gas port is in communication with the flue gas purification system 910, and the flue gas purification system 910 is used to remove various pollutants in the flue gas.

[0059] In the embodiment, the garbage storage area 100 is a square structure garbage pool 110 formed by stacking multiple concrete walls, and the sewage treatment area 200 is also a sewage treatment pool formed by stacking multiple concrete walls. Therefore, the garbage pool 110 and the sewage treatment pool form an entirety, and the joint part shares the concrete walls, so that the leachate collected can be connected to the sewage treatment pool for treatment in the shortest distance, thereby saving the corresponding conveying pipeline.

[0060] It can be understood that the sewage treatment pool includes multiple pool bodies separated by the concrete walls and arranged along the rear long end and the left short end of the garbage pool 110. In this way, the multiple separated pool bodies close to the garbage pool 110 can further provide favorable support for the garbage pool 110, effectively reducing the deformation of the garbage pool 110 caused by the load of the stacked garbage.

[0061] In the embodiment, the sewage treatment pool is an L-shaped pool body formed by multiple pool bodies. Specifically, the multiple pool bodies include a sludge pool 210, a primary sedimentation tank 220, a regulating pool 230, an intermediate water pool 240, an anaerobic sedimentation tank 250, an anoxic pool 260, an aerobic pool 270, and an anaerobic pool 300. Among them, the regulating pool 230, the anoxic pool 260, and the aerobic pool 270 are arranged from left to right at the rear edge of the garbage pool 110, the sludge pool 210 and the primary sedimentation tank 220 are arranged from left to right and located at the left end of the regulating pool 230, the intermediate water pool 240 and the anaerobic sedimentation tank 250 are arranged side by side from front to back at the right end of the regulating pool 230, and the anaerobic pool 300 is arranged at the left edge of the garbage pool 110, as shown in Figure 1

[0062] It can be understood that the bottom of the garbage pool 110 is provided with a leachate channel, and the sewage treatment area 200 further includes a leachate collection pool located below the regulating pool 230. The leachate channel and the leachate collection pool are connected by a pipeline. Since the regulating pool 230 is arranged close to the garbage pool 110, the leachate channel and the leachate collection pool can be connected by the shortest pipeline, thereby shortening the laying length of the pipeline, reducing the laying difficulty of the pipeline, and reducing the cost.

[0063] It can be understood that the sewage treatment area 200 further includes a membrane workshop, a dewatering room, and a fan room. The membrane workshop is located behind the anoxic pool 260 and the aerobic pool 270, and the fan room and the dewatering room are located right of the aerobic pool 270 from front to back.

[0064] In the embodiment, the bottom elevation of the garbage pool 110 is -6 meters, and the bottom elevation of the sewage treatment pool is -3.5 meters. The bottom elevation of the garbage pool 110 and the bottom elevation of the sewage treatment pool can be appropriately adjusted according to the actual garbage treatment capacity. The bottom elevation of the sewage treatment pool is not greater than the depth of the garbage pool 110.

[0065] ​It can be understood that the anaerobic tank 300 also includes anaerobic water pump, water seal tank and other auxiliary equipment.

[0066] It can be understood that the landfill leachate adopts the treatment process of "pretreatment + UASB anaerobic reactor + MBR + NF + RO", and the treatment process is as follows:

[0067] 1) The landfill leachate in the landfill tank 110 is introduced into the leachate channel through diversion, and after the large particle suspended solids and floating substances in the leachate are removed by the coarse grid, the leachate enters the leachate collection tank.

[0068] 2) The leachate in the collection tank is transported into the self-cleaning filter by the leachate delivery pump, and after the particle suspended solids and floating substances in the leachate are further removed, the leachate enters the leachate primary sedimentation tank 220.

[0069] 3) After the sedimentation treatment, most of the suspended solids (SS) and part of the insoluble organic matter are removed, and the leachate flows into the adjustment tank 230 by itself, and the leachate in the adjustment tank 230 is uniformly mixed and then lifted by the lifting pump to the anaerobic tank 300.

[0070] 4) The leachate in the adjustment tank 230 is lifted into the UASB anaerobic reactor by the anaerobic water pump, and the UASB anaerobic reactor includes the anaerobic tank 300, the anaerobic sedimentation tank 250 and the intermediate tank 240. The leachate is subjected to anaerobic fermentation treatment in the UASB anaerobic reactor, the chain links or benzene rings of high molecular substances are opened, and the large molecular refractory organic matter is decomposed into small molecular organic matter which is easy to biodegrade, and finally converted into methane, carbon dioxide and water.

[0071] 5) The leachate treated by the UASB anaerobic reactor flows into the anoxic / oxic (A / O) biochemical denitrification treatment system in sequence. In the anoxic / oxic, the nitrifying bacteria oxidize ammonia nitrogen to nitrate nitrogen under the oxic condition of the oxic tank 270 (O tank). The leachate treated in the nitrification tank is backflowed to the denitrification tank by a large backflow amount, mixed with the leachate, and under the anoxic condition of the anoxic tank 260 (A tank), the denitrifying bacteria reduce the nitrate to nitrogen gas and escape. Under the alternating conditions of anoxic and oxic, most of the organic matter and nitrogen are removed.

[0072] 6) After the water treated by the A / O biochemical system enters the membrane workshop, the water is pressurized by the ultrafiltration (UF) system water pump to enter the external MBR ultrafiltration membrane system for sludge-water separation. Most of the particles and colloidal organic matter in the water are intercepted, and the effluent enters the NF nanofiltration system treatment water tank.

[0073] 8) After the effluent treated by the MBR ultrafiltration membrane system enters the NF nanofiltration membrane system to remove most of the divalent ions and organic matter with a molecular weight of 200-1000, the effluent enters the NF nanofiltration clear liquid tank.

[0074] 9) The NF system processes the effluent water through the RO reverse osmosis pump to pressurize the RO reverse osmosis system for further processing, which can remove almost all impurities in the water, such as various monovalent ions, inorganic salts, molecules, organic colloids, bacteria, pathogens, etc. Ensure that the effluent water meets the relevant standard requirements for the heavy chromate index (COD cr ), ammonia nitrogen, total nitrogen, heavy metal ions, etc.

[0075] It can be understood that the sewage treatment area 200 is provided with a discharging platform area 600, and the garbage pool 110 extends upward and downward. The discharging platform area 600 corresponds to the front and back of the garbage pool 110, and the two are connected through two discharging doors 610. The garbage can be poured from the discharging platform area 600 to the garbage pool 110, and the upper space of the sewage treatment area 200 is reasonably used as the discharging platform area 600 for pouring garbage, as shown in Figure 2 and Figure 5 .

[0076] It can be understood that the top of the sewage treatment area 200 is a sewage treatment roof 280, as shown in Figure 4 . The ramp 620 is located at one end of the discharging platform area 600 away from the garbage storage area 100, as shown in Figure 5 . In this embodiment, the ramp 620 is located above the sewage treatment roof 280, and the left end of the ramp 620 is connected to the outdoor factory ground surface with a height of 0 meters, and the right end of the ramp 620 is connected to the left rear end of the discharging platform area 600 with a height of 6 meters, so that the garbage transport vehicle can enter the discharging platform area 600 from the outdoor factory ground surface through the ramp 620.

[0077] It can be understood that the discharging platform area 600 is a discharging hall. The top of the discharging platform area 600 is a discharging platform roof 650 with a height of 15 meters, which can use a steel girder to support a light steel structure roof panel, as shown in Figure 6 and Figure 7 .

[0078] It can be understood that since multiple pool bodies need to be provided with various pipes, pumps, etc. so that the garbage leachate can be treated in sequence in each pool body, a pipe interlayer 630 is further provided between the sewage treatment area 200 and the discharging platform area 600, so that the garbage leachate is treated in sequence along the sewage treatment process, as shown in Figure 2 .

[0079] It can be understood that the pipe interlayer 630 reasonably utilizes the height space between the sewage treatment area 200 and the discharging platform area 600.

[0080] In the embodiment, the sewage treatment roof 280 is 4 meters high, and the bottom of the unloading hall is 6 meters high. The height of the pipe interlayer 630 is 2 meters, which can be adjusted according to the actual project conditions.

[0081] It can be understood that the periphery of the garbage pool 110 can also be provided with 2-3 floors according to the functional requirements, as the functional room requirements of the project, and also as the supporting floor of the garbage pool 110 to meet the structural stability. The floor is a concrete platform, which forms a structural whole with the multi-layer floor and the garbage pool 110, supporting the garbage pool 110.

[0082] It can be understood that at a height of 7 meters to 23 meters, the right end edge of the garbage pool 110 is provided with a standby room 120, a washroom 130 and a visit corridor 140 with a height of 7 meters, all of which are located above the power distribution area 510. The standby room 120 and the washroom 130 are arranged from front to back and located between the visit corridor 140 and the garbage pool 110, as shown in Figure 5 .

[0083] It can be understood that the top of the anaerobic tank 300 is provided with a sampling room in the front and a hoisting site 640 in the rear, which are arranged along the left end edge of the garbage pool 110. The sampling room is 7 meters high, and the hoisting site 640 is located on the unloading platform area 600 with a height of 6 meters, as shown in Figure 5 . The sampling room and the hoisting site 640 are connected by a left corridor.

[0084] It can be understood that the standby room 120, the washroom 130, the visit corridor 140 and the sampling room can be provided with multiple floors and the height can be adjusted according to the specific conditions of the project.

[0085] It can be understood that the upper part of the garbage storage area 100 is provided with a feeding platform area 700, as shown in Figure 6 . The feeding platform area 700 is provided with a grab bucket 710, as shown in Figure 2 . The feeding platform area 700 is connected with the garbage storage area 100, so that the grab bucket 710 can move horizontally and downwardly into the garbage pool 110. The feeding platform area 700 is connected with the feeding port 420 of the incinerator 411, so that the grab bucket 710 can grab the garbage into the feeding port 420 of the incinerator 411.

[0086] In the embodiment, the feeding port 420 of the incinerator 411 is upwardly open, and the feeding platform area 700 is also located above the rear end of the boiler incineration area 400. The feeding port 420 of the incinerator 411 is opposite to the feeding platform area 700 and connected with each other, as shown in Figure 2 .

[0087] Thus, after the grab bucket 710 picks up the garbage from the garbage pool 110, the grab bucket 710 is first moved upward to the feeding platform area 700, then horizontally moved to above the incinerator 411, the grab bucket 710 is controlled to be loosened, so that the picked garbage naturally falls downward into the feeding inlet 420 of the incinerator 411, and the garbage enters the incineration process.

[0095] As can be understood, the top of the turbine generator area 530, the top of part of the central control room 520, and the top of part of the visit corridor 140 are a turbine room roof 531 with a height of 22 meters, with the front end of the feeding platform 730 as a boundary line, as shown in Figure 6 and Figure 7 .

[0096] As can be understood, the boiler incineration area 400 includes an incineration room 410, and the bottom surface of the incineration room 410 is 0 meters high. The steel column frame supporting the incinerator 411 is arranged on the 0-meter bottom surface of the incineration room 410, as shown in Figure 2 , Figure 4 and Figure 5 . The boiler incineration area 400 and the ash storage area 800 are arranged with a front platform 440 and a rear platform 450, as shown in Figure 5As shown, the front furnace platform 440 and part of the rear furnace platform 450 are located above the incineration room 410 and arranged around the incinerator 411, and the front furnace platform 440 and the rear furnace platform 450 are used to provide a working space for workers to observe the furnace condition, check the equipment, and the like.

[0097] In this embodiment, the elevations of the front furnace platform 440 and the rear furnace platform 450 are 7 meters.

[0100] As can be understood, the steam turbine power generation area 530 is connected with the front end of the power distribution area 510 and the front end of the central control room 520, and the principle of near power distribution line and the principle of near control power generation mode are preferably realized.

[0101] As can be understood, the integrated garbage incineration power plant layout structure further includes an on-grid power distribution area 540, as shown in Figure 1 The on-grid power distribution area 540 is located at the end close to each other between the steam turbine power generation area 530 and the flue gas treatment area 900. The on-grid power distribution area 540 includes a main transformer room 541 and a high-voltage power distribution room 542 arranged from left to right, so as to facilitate the cable line of the protection control equipment of the central control room 520 to be closest, and reduce the amount of cable used, as shown in Figure 1 、 Figure 4 and Figure 5 .

[0102] In this embodiment, the bottom elevation of the on-grid power distribution area 540 is 0 meters, and the top of the on-grid power distribution area 540 is an on-grid power distribution roof 543 with an elevation of 12 meters, as shown in Figure 6 and Figure 7 . The on-grid power distribution roof 543 can adopt a concrete roof or a light steel roof.

[0103] As can be understood, the flue gas treatment area 900 further includes a chimney 920, which is used to discharge the flue gas treated to reach the environmental protection standard to the outside. The chimney 920 is provided with a monitoring device, which is used to monitor in real time and feed back the flue gas treatment data of the discharge to the central control room 520, so as to enable the control personnel to reasonably allocate the equipment and treatment measures of the flue gas purification system 910.

[0104] Further, the integrated garbage incineration power plant layout structure can further include a display screen, and the monitoring device is electrically connected with the display screen, so as to display the waste treatment data on the power plant large screen for public supervision and inspection.

[0105] It can be understood that the chimney 920 is arranged at the rear end or rear corner of the flue gas purification system 910 to meet the flue gas emission. The chimney 920 can adopt a single-cylinder concrete chimney 920 or a self-standing single-cylinder steel chimney 920, and when the material of the chimney 920 is steel, the chimney 920 can also be directly hung on the lateral area of the building structure wall of the flue gas purification system 910, thereby reducing the foundation cost of separately arranging the chimney 920.

[0106] In the present embodiment, the elevation of the flue gas treatment area 900 is 0 meters. The top of the flue gas purification system 910 is a flue gas treatment roof 930 with an elevation of 40 meters, as shown in Figure 6 and Figure 7 The flue gas treatment roof 930 can be a light steel roof.

[0107] It can be understood that all flue gas of the waste incineration enters the waste heat boiler 840, and the temperature is reduced to about 190°C through the heating surface of each part of the waste heat boiler 840, and then enters the flue gas purification system 910 through the flue gas port. The flue gas purification system 910 adopts the mode of “selective non-catalytic reduction (SNCR) in-furnace denitration + semi-dry deacidification + dry injection + activated carbon adsorption + bag dust removal + wet deacidification + low-temperature selective catalytic reduction (SCR)” for treatment, and the flue gas treatment area 900 is also provided with a fly ash stabilization room 940, a lime slurry preparation room 950, an activated carbon room 960 and an alkali liquor preparation room 970 arranged from front to back, and located at the right side of the flue gas purification system 910, as shown in Figure 1 、 Figure 4 and Figure 5

[0108] ​It can be understood that the flue gas first enters the rotating spray reaction tower, in the reaction tower, the flue gas is in contact with the lime slurry (Ca(OH)2) sprayed into the rotating sprayer at the top of the tower to react, neutralize the acidic gas in the flue gas, and reduce the flue gas temperature. After the deacidification reaction, the flue gas enters the bag filter through the connecting pipe, the connecting pipe is provided with an activated carbon spraying inlet and a dry powder spraying inlet, the activated carbon can adsorb heavy metals and dioxins in the flue gas, and the dry powder can further neutralize the acidic gas in the flue gas and can pre-spray the new bag used for the first time; After the activated carbon adsorbs heavy metal compounds and dioxins, it is captured and collected by the bag filter, and the particles in the flue gas are also filtered and collected. The fly ash collected by the reaction tower and the bag filter is sent to the fly ash storage by the scraper conveyor and the bucket elevator. The flue gas collected by the bag filter and the low-temperature clean flue gas at the outlet of the wet deacidification tower are cooled and dehumidified by the flue gas desulfurization system (GGH), and then enter the wet tower. The flue gas in the wet tower reacts with sodium hydroxide solution to further remove acidic gas, and the deacidification tower outlet clean flue gas is heated by GGH and absorption tower system (SGC) and enters the SCR reactor. The SCR system uses ammonia water evaporation to quantitatively spray ammonia into the SCR reactor for catalytic denitration to reduce the concentration of nitrogen oxides (NO x ) at the outlet. The high-temperature flue gas after the SCR and the clean flue gas at the outlet of the deacidification tower are cooled by the GGH, and then discharged into the atmosphere by the induced draft fan and the chimney 920.

[0109] It can be understood that the fly ash intercepted in the flue gas treatment process is a hazardous waste, and the mass of the fly ash is much smaller than the mass of the garbage. The fly ash can be stabilized in the fly ash stabilization room 940 and then transported to a landfill for landfill, or can be transported to a fly ash treatment plant for further treatment to extract useful components from the fly ash.

[0110] It can be understood that since the boiler incineration area 400 and the ash storage area 800 do not need to be connected with the flue gas purification system 910 again, the roof space span of the boiler incineration area 400, the ash storage area 800 and the flue gas purification system 910 is greatly reduced, and the roofs of the three can use ordinary steel structures, which can save land area and save the cost of roof steel structure.

[0111] It can be understood that the roofs of the fly ash stabilization room 940, the lime slurry preparation room 950, the activated carbon room 960 and the alkali solution preparation room 970 are the flue gas auxiliary roof 980 with a height of 28 meters, as shown in Figure 6 and Figure 7 , the flue gas auxiliary roof 980 is a common concrete roof.

[0112] It can be understood that the ash storage area 800 includes a slag pool 810, a slag crane 820 and a loading site 830. Specifically, the slag pool 810 is upwardly open and located close to the incinerator 411, as shown in Figure 1 , Figure 4 andFigure 5 The end of the slag grab 430 is opposite to the front and back of the slag pool 810. The slag crane 820 is above the slag pool 810, as shown in Fig. 8. Figure 2 The slag is grabbed by the slag crane 820 to the slag truck in the loading area 830 for transportation. The slag is a harmless product which can be used for brick making or road paving.

[0113] In the embodiment, the bottom of the slag pool 810 is at the level of-4 meters, the loading area 830 is at the left of the slag pool 810 and at the level of 0 meters, and the back platform 450 at the level of 7 meters is arranged around the slag pool 810 and the loading area 830 to provide space for the installation and grabbing of the slag crane 820.

[0114] It can be understood that the integrated garbage incineration power plant layout structure can be used for garbage incineration power generation projects, other small thermal power plants, and can also be partially changed according to the specific terrain and project modification requirements, to maximize the use of different projects, save land area and investment.
