Abstract
Description
Technical Field
[0001] This application relates to the field of hazardous waste disposal technology, and in particular to a rigid landfill system. Background Technology
[0002] Rigid landfills are land-based hazardous waste disposal facilities designed in accordance with the "Standard for Pollution Control of Hazardous Waste Landfills" (GB 18598-2019) and using a rigid structure, mainly reinforced concrete, as the core seepage prevention and barrier system. Essentially, they are "reinforced concrete sealed boxes" that achieve physical isolation from the environment through artificial structures.
[0003] In existing technologies, the "Standard for Pollution Control of Hazardous Waste Landfill" (GB18598-2019) does not clearly define the structural types, anti-seepage schemes, and operation methods of rigid landfills. Different landfills employ significantly different design schemes, resulting in varying costs. Currently, a common structure and operation method for existing rigid landfills involves a fixed steel structure rain shelter above the landfill unit, with a crane track underneath for hoisting hazardous waste. This fixed rain shelter approach has high construction costs and a long construction period. Furthermore, after landfilling and closure, the rain shelter is essentially idle, making it uneconomical. Additionally, when using cranes for hoisting, since each crane can only lift one piece of waste at a time, the crane must frequently travel between the loading and landfill areas, leading to low operational efficiency and increased operating costs for the company. Summary of the Invention
[0004] The purpose of this application is to provide a rigid landfill system that can solve the problem of low operational efficiency.
[0005] To achieve the above objectives, this application provides a rigid landfill system, comprising: multiple landfill units, a partition layer, a hoisting mechanism, and a transfer platform;
[0006] The landfill unit is used to store hazardous materials;
[0007] The partition layer is located below the landfill unit and is used to separate the landfill unit from the soil;
[0008] The hoisting mechanism is used to transport hazardous materials to the landfill unit;
[0009] The transfer platform is equipped with a moving device at its bottom, which enables the transfer platform to move. The transfer platform has a movable cover plate that can rotate relative to the transfer platform. The transfer platform can move to above the landfill unit and cover the landfill unit.
[0010] In some embodiments, the bottom of the landfill unit has a slope, and a water collection pit is formed at the lowest point of the bottom of the landfill unit.
[0011] In some embodiments, the inner surface of the landfill unit is provided with a protective film.
[0012] In some embodiments, the net height of the partition layer is 1.6 to 2.5 meters, and the lower part of the partition layer is a hardened floor with a permeability coefficient not exceeding [a certain value]. cm / s.
[0013] In some embodiments, the hoisting mechanism includes a frame, a track, a lateral movement assembly, a longitudinal movement assembly, and a hook. The frame is disposed on the ground, the track is disposed on the frame and located above the landfill unit, the lateral movement assembly is slidably engaged with the track and is capable of lateral movement along the track, the longitudinal movement assembly is slidably engaged with the lateral movement assembly and is capable of longitudinal movement along the lateral movement assembly, and the hook is disposed on the longitudinal movement assembly.
[0014] In some embodiments, the transfer platform is surrounded by a protective fence.
[0015] In some embodiments, the transfer platform is provided with a support beam at its lower part.
[0016] In some embodiments, the transfer platform is further provided with a drainage ditch, which is inclined and the bottom end of the drainage ditch is located at the edge of the transfer platform.
[0017] In some embodiments, a rainwater and sewage separation unit is also provided, which includes a sewage collection ditch and a rainwater collection ditch. The sewage collection ditch is located on the periphery of the area where the landfill unit is located, and the rainwater collection ditch is located on the periphery of the sewage collection ditch.
[0018] In some embodiments, the hook is equipped with a camera and an automatic release device, which is capable of automatically releasing the dangerous goods attached to the hook.
[0019] Compared to the aforementioned background technology, the rigid landfill system provided in this application includes multiple landfill units, a partition layer, a hoisting mechanism, and a transfer platform. The landfill units are used to store hazardous materials. The partition layer is located below the landfill units and is used to separate the landfill units from the soil. The hoisting mechanism is used to transport hazardous materials to the landfill units. The bottom of the transfer platform is equipped with a moving device, which enables the transfer platform to move. The transfer platform has a movable cover plate, which can rotate relative to the transfer platform. The transfer platform can move above the landfill units and cover the landfill units. The transfer platform is first moved to the loading and unloading area of the plant. Hazardous materials sent to the plant are transported to the loading and unloading area by dedicated vehicles. The hoisting mechanism lifts the hazardous materials from the loading and unloading area onto the transfer platform. Then, the transfer platform moves above the landfill unit, opens the movable cover, and uses the hoisting mechanism to place the hazardous materials on the transfer platform sequentially into the landfill unit below the transfer platform until the landfill unit is full. Then, the transfer platform moves to the next landfill unit and repeats the above operation until the landfill unit is full of hazardous materials. When all landfill units are full of hazardous materials, the landfill is sealed off. Because the hoisting mechanism first lifts the hazardous materials from the loading and unloading area to the transfer platform, and then lifts the hazardous materials from the transfer platform to the landfill unit when the transfer platform moves above the landfill unit, the total travel distance of the hoisting mechanism is reduced, transportation efficiency is improved, and operating costs are reduced. When it rains, the landfill operation is not carried out. At this time, the transfer platform covers the landfill unit, which can act as a rain shelter to prevent rainwater from entering the landfill unit. This reduces the investment in fixed canopies during construction, thereby reducing construction costs and shortening the construction period. Attached Figure Description

Detailed Implementation
[0026] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0027] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0028] It should be noted that the directional terms such as "upper end," "lower end," "left side," and "right side" mentioned below are defined based on the accompanying drawings in the instruction manual.
[0029] like Figures 1 to 3 As shown, the rigid landfill system provided in this application embodiment includes multiple landfill units 1, partition layers 2, hoisting mechanisms 3, and transfer platforms 4. The landfill units 1 are used to store hazardous materials. The partition layers 2 are located below the landfill units 1 and are used to separate the landfill units 1 from the soil. The hoisting mechanisms 3 are used to transport hazardous materials to the landfill units 1. The transfer platform 4 is equipped with a moving device at its bottom and can be moved by the moving device. The transfer platform 4 has a movable cover plate 41, which can rotate relative to the transfer platform 4. The transfer platform 4 can be moved to above the landfill units 1 and cover the landfill units 1.
[0030] Understandably, the transfer platform 4 first moves to the loading and unloading area of the plant. Hazardous materials delivered to the plant are transported to the loading and unloading area by dedicated vehicles. The hoisting mechanism 3 hoists the hazardous materials from the loading and unloading area onto the transfer platform 4. Then, the transfer platform 4 moves above the landfill unit 1, opens the movable cover 41, and uses the hoisting mechanism 3 to place the hazardous materials from the transfer platform 4 into the landfill unit 1 below it, until the landfill unit 1 is full. The transfer platform 4 then moves to the next landfill unit 1, repeating the above operation until the landfill unit 1 is full of hazardous materials. When all landfill units 1 are full of hazardous materials, the site is sealed off. Because the hoisting mechanism 3 first hoists the hazardous materials from the loading and unloading area to the transfer platform 4, and then hoists them from the transfer platform 4 to the landfill unit 1 when the transfer platform 4 moves above the landfill unit 1, the total travel distance of the hoisting mechanism 3 is reduced, transportation efficiency is improved, and operating costs are reduced. When it rains, the landfill operation is not carried out. At this time, the transfer platform 4 covers the landfill unit 1, thus serving as a rain shelter to prevent rainwater from entering the landfill unit 1. This reduces the investment in fixed canopies during construction, thereby reducing construction costs and shortening the construction period.
[0031] In some embodiments, the bottom of the landfill unit 1 has a slope, and a water collection pit is formed at the lowest point of the bottom of the landfill unit 1.
[0032] Specifically, the landfill unit 1 is made of reinforced concrete and has a rectangular trough structure. The bottom of the landfill unit 1 has a slope so that the bottom surface of the landfill unit 1 forms a water collection pit. The water collection pit can be a concave cone-shaped trough.
[0033] Understandably, by setting up a water collection pit, if water accidentally enters landfill unit 1, the water will collect in the water collection pit, and the water in the water collection pit can be drained by a vacuum pump, thus preventing the continuous accumulation of water in landfill unit 1 and affecting the landfill operation.
[0034] In some embodiments, a protective film is provided on the inner surface of the landfill unit 1.
[0035] Specifically, the protective membrane can be an HDPE membrane with a thickness of 2 mm. The protective membrane has anti-corrosion and anti-seepage functions. By covering the landfill unit 1 with the protective membrane, environmental risks are further reduced and hazardous material leakage is avoided.
[0036] In some embodiments, the clear height of partition layer 2 is 1.6 to 2.5 meters, and the lower part of partition layer 2 is a hardened floor with a permeability coefficient not exceeding [a certain value]. cm / s.
[0037] Specifically, the clear height of the partition layer 2 in this embodiment can be 2 meters.
[0038] Understandably, partition layer 2 provides space for personnel to conduct maintenance, facilitates regular inspections by workers, and enables timely remediation in the event of a hazardous material leak. The hardened concrete floor can prevent hazardous materials leaked from landfill unit 1 from seeping into the ground.
[0039] In some embodiments, the hoisting mechanism 3 includes a frame 31, a track 32, a transverse moving component 33, a longitudinal moving component 34, and a hook 35. The frame 31 is located on the ground, the track 32 is located on the frame 31 and above the landfill unit 1, the transverse moving component 33 is slidably engaged with the track 32 and is capable of moving laterally along the track 32, the longitudinal moving component 34 is slidably engaged with the transverse moving component 33 and is capable of moving longitudinally along the transverse moving component 33, and the hook 35 is located on the longitudinal moving component 34.
[0040] Specifically, the frame 31 is detachably mounted on the ground at the landfill unit 1. There are two parallel tracks 32, both fixedly mounted on the upper part of the frame 31. The lateral movement component 33 can be a lateral movement trolley, with its top slidably engaged with each of the two tracks 32. The lateral movement trolley can move laterally along the extension direction of the two tracks 32. The longitudinal movement component 34 can be a longitudinal movement trolley, with a longitudinal sliding rail at its bottom. The longitudinal movement trolley slidably engages with the longitudinal sliding rail and can move relative to the lateral movement trolley along the longitudinal sliding rail. A hook is mounted on the longitudinal movement trolley, allowing the hook to move within a plane through the movement of the lateral and longitudinal movements. A winch is also provided next to the frame 31, connected to the hook via a rope, enabling the hook to be raised and lowered.
[0041] In some embodiments, the transfer platform 4 is provided with a protective fence 42 around its perimeter.
[0042] Specifically, the height of the protective fence 42 is 1.3 meters.
[0043] Understandably, setting up protective fence 42 can prevent workers from falling from transfer platform 4 while working on the transfer platform, and can also prevent dangerous goods from sliding off transfer platform 4, thereby improving safety.
[0044] In some embodiments, the transfer platform 4 is provided with a support beam at its lower part.
[0045] Understandably, the support beams are made of carbon steel, and setting up support beams can improve the load-bearing capacity of transfer platform 4 and prevent transfer platform 4 from collapsing.
[0046] In some embodiments, the transfer platform 4 is further provided with a drainage ditch 43, which is inclined and the bottom end of the drainage ditch 43 is located at the edge of the transfer platform 4.
[0047] Specifically, there are two drainage ditches 43, which are respectively set on both sides of the transfer platform 4. The transfer platform 4 has a double-sloped structure with a slope of 1.5. The movable cover plate 41 is the highest point of the double-sloped structure of the transfer platform 4, and the drainage ditches 43 on both sides of the transfer platform 4 are the lowest points of the double-sloped structure. The drainage ditches 43 are distributed at an incline with a slope of 3%. The bottom of the drainage ditches 43 is located at the edge of the transfer platform 4. The water in the drainage ditches 43 can flow downward along the drainage ditches 43 and be discharged from the edge of the transfer platform 4 to the outside of the landfill area.
[0048] Understandably, the drainage ditch 43 can guide and drain rainwater from the transfer platform 4 in rainy weather, preventing rainwater from accumulating on the transfer platform 4.
[0049] In some embodiments, a rainwater and sewage separation unit is also provided, which includes a sewage collection ditch 5 and a rainwater collection ditch 6. The sewage collection ditch 5 is located on the periphery of the area where the landfill unit 1 is located, and the rainwater collection ditch 6 is located on the periphery of the sewage collection ditch 5.
[0050] Specifically, such as Figure 1 and Figure 3 As shown, the sewage collection ditch 5 is located on the periphery of the landfill area and forms a rectangle. Sewage collection pits 51 are also provided at the corners of the rectangular sewage collection ditch 5. The dimensions of the sewage collection pits 51 are 2m × 2m × 2m. The water inside the sewage collection pits 51 is periodically discharged by a submersible pump. The permeability coefficient of the sewage collection ditch 5 and the sewage collection pits 51 is no higher than […]. cm / s, rainwater collection ditch 6 is located outside sewage collection ditch 5, rainwater collection ditch 6 is connected to landfill unit 1 by rainwater drainage pipe 7, and the upper part of landfill unit 1 is provided with sleeve, which is connected to rainwater drainage pipe 7.
[0051] Understandably, the sewage collection ditch 5 is used to collect sewage discharged from the drainage ditch 43 of the transfer platform 4, flushing water from the partition layer 2, and flushing water from the unloading area, preventing sewage from flowing out. The rainwater collection ditch 6 is used to collect clean rainwater after the landfill unit 1 is closed. After the landfill unit 1 is closed, the landfill unit 1 is poured with concrete, and a slope is set on the top of the landfill unit 1. The lowest point of the slope is the casing. Rainwater falling on the top of the landfill unit 1 can flow along the slope to the casing and enter the rainwater collection ditch 6 through the rainwater drainage pipe 7.
[0052] In some embodiments, the hook 35 is equipped with a camera and an automatic release device, which can automatically release the dangerous goods attached to the hook 35.
[0053] Specifically, the camera is electrically connected to an external monitoring screen. The camera can capture whether the hook 35 has placed the hazardous materials in place inside the landfill unit 1. The automatic release device is an electromagnetic lock release device in conventional technology. The connection between the hook 35 and the hazardous materials can be released by remote control, thereby avoiding frequent entry of personnel into the landfill unit 1 and improving safety.
[0054] In summary, the rigid landfill system of this application utilizes the transfer platform 4 to reduce the total stroke of the hoisting mechanism 3, improve operational efficiency, and thus reduce operational investment. The transfer platform 4 can also serve as a temporary canopy, avoiding the installation of a fixed canopy, reducing engineering investment, lowering construction costs, and shortening the construction period. At the same time, the installation of the partition layer 2, sewage collection ditch 5, and rainwater collection ditch 6 allows for direct inspection and monitoring of leakage, further preventing leachate pollution of the environment. The sewage collection ditch 5 and rainwater collection ditch 6 enable separation of rainwater and sewage, reducing the pressure on the sewage treatment system.
