Description

Technical Field

[0001] This utility model relates to the field of pipeline anti-leakage technology, and in particular to a leakage prevention buffer device and leakage early warning system for leachate pipelines. Background Technology

[0002] Leachate pipelines are specialized piping systems used to transport leachate, which is mostly generated in landfills, composting sites, and other similar locations. Leachate is a high-concentration organic wastewater that seeps out during the storage and decomposition of waste, containing a large number of pollutants. Leachate pipelines must have good corrosion resistance to resist the erosion of chemicals in the leachate, and at the same time, they must have a certain degree of sealing to prevent leachate leakage and environmental pollution. They are usually composed of the pipeline body, connectors, valves, etc. Through reasonable layout and installation, leachate is safely and stably transported to treatment facilities for purification treatment, ensuring environmental safety.

[0003] However, the anti-seepage layer of traditional leachate pipes is mostly a single HDPE membrane. When the pipe leaks, the single membrane is difficult to effectively block the leachate, which can easily lead to leakage and pollution of the external environment.

[0004] For example, at a landfill, a section of traditional leachate pipe developed cracks due to long-term corrosion. The single HDPE membrane geomembrane was quickly ruptured by the leachate, and a large amount of leachate seeped into the surrounding soil, causing soil compaction, decreased fertility, and pollution of nearby groundwater. The growth of surrounding vegetation was also severely affected. Utility Model Content

[0005] This utility model discloses a leachate pipeline anti-leakage buffer device and a leakage early warning system, aiming to solve the technical problem that the anti-leakage layer is mostly a single HDPE membrane. When the pipeline leaks, the single membrane is difficult to effectively block the leachate, which can easily lead to its leakage and thus cause pollution to the external environment.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A leakage prevention buffer device for leachate pipeline includes a pipeline body and two flanges, and a buffer mechanism is provided on the outer circumferential wall of the pipeline body.

[0008] The buffer mechanism includes an inner membrane and an outer membrane. The inner membrane is disposed on the outer circumferential wall of the pipe body. A buffer cavity is formed between the inner membrane and the outer membrane. A plurality of equidistant diaphragms are disposed on the inner wall of the buffer cavity. A plurality of equidistant liquid collection ports are opened on the inner wall of the buffer cavity. A collection pipe is disposed at one end of each liquid collection port.

[0009] By adopting the above technical solution and employing a double-layer protective structure, the pipeline's anti-leakage capability is enhanced. The inner and outer membranes are made of specially modified HDPE membranes, which combine pressure resistance, impermeability, and chemical stability. The diaphragm is a fluorinated polymer composite membrane, which is corrosion-resistant, has a strong seal, and a long service life. The three membranes work together to achieve efficient sealing and independent separation of the buffer chamber, significantly improving the reliability of the device against leakage. When a tiny crack appears in the pipeline body, the leachate will quickly pass through the inner membrane with one-way permeation function into the buffer chamber. The chamber is scientifically divided into independent small chambers by the fluorinated polymer composite diaphragm, effectively limiting the liquid diffusion range. Subsequently, the leachate flows directionally into the corresponding collection pipe through the collection port under the action of gravity, avoiding direct leakage, buying time for emergency treatment, and reducing the risk of environmental pollution. In practical applications, an inspection port is set at certain intervals during pipeline installation to facilitate subsequent inspection and maintenance.

[0010] The leachate pipeline leakage early warning system includes the aforementioned leachate pipeline leakage prevention buffer device, and also includes several equally spaced electrode rings. The electrode rings are disposed on the inner wall of the buffer chamber, and every three electrode rings are externally connected to the same alarm component.

[0011] By adopting the above technical solution, the electrode rings monitor the liquid in the buffer chamber in real time, realizing early warning of leaks. This significantly shortens the response time from several hours of traditional manual inspections and greatly reduces the risk of environmental pollution. Multiple sets of electrode rings are installed at equal intervals on the inner wall of the buffer chamber. Each set contains positive and negative electrodes and is connected to an external alarm component through waterproof wires. The alarm component integrates a battery-powered wireless signal transmission module. When a leak occurs, an alarm is sent to the monitoring platform, and the valve at the delivery end is closed in time. When leachate enters the buffer chamber and contacts the electrode rings, the circuit is activated and the alarm is triggered. The system also records the leak location and pushes it to the maintenance terminal.

[0012] In summary, this application includes at least one of the following beneficial technical effects:

[0013] 1. Multiple protections enhance leak prevention. The device uses a double-layer specially modified HDPE membrane and a fluoropolymer composite diaphragm. The three membranes work together to efficiently seal the buffer chamber, limiting the diffusion of leachate, avoiding large-area leaks, buying time for emergency response, reducing the risk of pollution, and extending pipeline life.

[0014] 2. Real-time early warning and rapid risk response. Multiple sets of electrode rings are installed in the buffer chamber. The alarm is triggered as soon as the leachate comes into contact with the rings, and the location of the leak is wirelessly pushed to the maintenance department, shortening the response time and enabling early warning.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The leachate pipeline anti-leakage buffer device includes a pipeline body 10 and two flanges 2. A buffer mechanism is provided on the outer circumferential wall of the pipeline body 10. The buffer mechanism includes an inner membrane 12 and an outer membrane 1. The inner membrane 12 is provided on the outer circumferential wall of the pipeline body 10, and a buffer cavity is formed between the inner membrane 12 and the outer membrane 1. A number of equidistant diaphragms 13 are provided on the inner wall of the buffer cavity. A number of equidistant liquid collection ports 11 are opened on the inner wall of the buffer cavity. A collection pipe 4 is provided at one end of the liquid collection port 11.

[0023] In the specific implementation process, a buffer mechanism is set on the outer circumference of the pipeline body 10, and a double-layer protective structure is adopted to improve the pipeline's anti-leakage capability. The inner membrane 12 and the outer membrane 1 are made of specially modified HDPE membrane, which has the advantages of pressure resistance, impermeability and chemical stability. The diaphragm 13 is made of fluorinated polymer composite membrane, which is corrosion resistant, strong sealing and long service life. The three membranes work together to achieve efficient sealing and independent separation of the buffer chamber, which greatly improves the reliability of the device in preventing leakage. When a small crack appears in the pipeline body 10, the leachate will quickly pass through the inner membrane 12 with one-way permeation function and enter the buffer chamber. The chamber is scientifically divided into independent small chambers by the fluorinated polymer composite diaphragm 13, which effectively limits the liquid diffusion range. Then, under the action of gravity, the leachate flows into the corresponding collection pipe 4 through the liquid collection port 11 to avoid direct leakage, buy time for emergency treatment and reduce the risk of environmental pollution. In practical applications, an inspection port is set at a certain distance when the pipeline is buried to facilitate later inspection and maintenance.

[0024] Reference Figure 1 , Figure 2 and Figure 4 In a preferred embodiment, one end of several collection pipes 4 is connected to a drain pipe 6, one end of the drain pipe 6 is provided with an emergency pump 7, the emergency pump 7 is connected to a connecting pipe 8, one end of the connecting pipe 8 is provided with a collection tank 9, and two flanges 2 are respectively provided at both ends of the pipe body 10.

[0025] Specifically, by linking the drainage pipe 6 with the emergency pump 7, the leakage leachate can be quickly collected and transferred, preventing the liquid from accumulating in the buffer chamber and causing excessive pressure on the outer membrane 1, thus further reducing the risk of leakage. A collection port 11 is opened at the bottom of the buffer chamber, and the liquid is guided to the drainage pipe 6 through the collection pipe 4. An emergency pump 7 is installed at the end of the drainage pipe 6. The pump outlet is connected to the collection tank 9 through the connecting pipe 8, forming a closed leakage treatment system to avoid secondary pollution, while simplifying the operation process and improving the efficiency of emergency response.

[0026] Reference Figure 1 , Figure 2 and Figure 3 The leachate pipeline leakage early warning system includes the aforementioned leachate pipeline leakage prevention buffer device, and also includes several equally spaced electrode rings 14. The electrode rings 14 are disposed on the inner wall of the buffer chamber, and every three electrode rings 14 are externally connected to the same alarm component.

[0027] Specifically, by using electrode rings 14 to monitor the liquid in the buffer chamber in real time, early warning of leaks can be achieved, significantly reducing the response time from several hours of traditional manual inspections and greatly reducing the risk of environmental pollution. Multiple sets of electrode rings 14 are installed at equal intervals on the inner wall of the buffer chamber. Each set contains positive and negative electrodes and is connected to an external alarm component via waterproof wires. The alarm component 5 integrates a battery-powered wireless signal transmission module. When a leak occurs, an alarm is sent to the monitoring platform, and the valve at the delivery end is closed in time. When leachate enters the buffer chamber and contacts the electrode rings 14, the circuit is activated and the alarm is triggered. The system also records the leak location and pushes it to the maintenance terminal.

[0028] Reference Figure 3 and Figure 4 In a preferred embodiment, a sealing layer is provided on the outer wall of the electrode ring 14, and the sealing layer is made of polyvinylidene fluoride.

[0029] It should be noted that polyvinylidene fluoride is used as the sealing layer, which has excellent insulation properties that do not interfere with electrode conductivity. It is also resistant to acids and alkalis, corrosion-resistant, and can resist leachate erosion. It has high mechanical strength and can withstand pipeline vibration and deformation. The surface treatment can reduce the amount of deposits. It has both sealing protection and anti-false triggering functions, thus extending the service life of the equipment.

[0030] Working principle: During use, the pipeline body 10 transports leachate. If a tiny crack appears, the leachate enters the buffer chamber through the inner membrane 12 with one-way permeation function. The fluorinated polymer composite diaphragm 13 divides the buffer chamber into independent small chambers, limiting the liquid diffusion range. The leachate then passes through the collection port 11, collection pipe 4, and guide pipe 6, and is pumped by the emergency pump 7 to the collection tank 9 to prevent leakage. At the same time, the electrode ring 14 on the inner wall of the buffer chamber can monitor the liquid in real time. When the leachate contacts the electrode ring 14, the positive and negative electrode circuits are connected, triggering the alarm component 5. Its wireless signal transmission module sends an alarm to the monitoring platform, records the leak location, and pushes it to the maintenance terminal. Maintenance personnel can quickly locate and handle the leak. In addition, the inspection port set during pipeline installation facilitates later inspection and maintenance.

The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
