[0002] An anaerobic reactor is a biological treatment device used to treat organic wastewater and solid waste. Through the action of anaerobic microorganisms, complex organic matter is broken down into simpler compounds, producing biogas (the main components of which are methane and carbon dioxide). It is widely used in wastewater treatment and other fields.

[0003] Anaerobic reactors typically consist of a tank and an air-filled roof mounted on top of the tank. The air-filled roof floats up and down within the tank as the biogas volume changes. Therefore, the biogas volume within the tank can be determined by monitoring the level of the air-filled roof. However, existing level monitoring methods can only intermittently monitor the highest and lowest points of the air-filled roof, and cannot monitor the real-time position of the roof and its corresponding biogas volume. This limitation makes it difficult to accurately grasp the dynamic changes of biogas within the tank during actual operation, thus affecting the rational planning and efficient management of biogas use.

[0026] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0027] like Figures 1 to 6 As shown, this embodiment of the invention provides an anaerobic reaction system capable of real-time monitoring of biogas production, including an anaerobic reactor, a level monitoring device, a central control module, and a flare. The anaerobic reactor is used to decompose organic matter in an anaerobic environment through the action of anaerobic microorganisms, producing biogas (mainly composed of methane and carbon dioxide). The anaerobic reactor includes a tank 11, an air bladder 12, and a weight block 13. The air bladder 12 is located inside the tank 11 and at the top of the tank 11, and can float up and down inside the tank 11. The weight block 13 is slidably disposed outside the tank 11 and is connected to the air bladder 12 by a connector such as a steel wire rope. It should be noted that multiple weight blocks 13 are provided, and all multiple weight blocks 13 are connected to the air bladder 12 and are arranged sequentially at intervals along the circumference of the air bladder 12. The weight block 13 is used to pull the air bladder 12 to move downward inside the tank 11. When biogas is generated inside the tank 11, the gas pressure inside the tank 11 increases, causing the air bladder 12 to move upward against the pulling force of the weight block 13. A level monitoring device is installed outside the tank 11 and monitors the level information of the airbag 12 in conjunction with a weight block 13. Multiple level monitoring devices can be installed, each corresponding to a weight block 13, or only one device can be installed, with each device working with only one weight block 13. Since the weight block 13 moves synchronously with the airbag 12, the level of the airbag 12 inside the tank 11 can be obtained by monitoring the position of the weight block 13. A flare is used to treat methane exceeding storage or utilization capacity produced by the anaerobic reactor through combustion. Preferably, both the level monitoring device and the flare are electrically connected to a central control module. The central control module controls the flare's operation based on the level information of the airbag 12 monitored by the level monitoring device. That is, when the level monitoring device detects that the level of the airbag 12 exceeds a preset value, the central control module controls the flare to open; when the level monitoring device detects that the level of the airbag 12 returns to or falls within the preset value, the central control module controls the flare to close. The central control module is a central control unit located in the central control room of the anaerobic reaction system plant, which is capable of real-time monitoring of biogas production.

[0028] The anaerobic digester system provided in this embodiment, which can monitor biogas volume in real time, monitors the level information of the gas bladder 12 in conjunction with the load block 13 and feeds the level information of the gas bladder 12 back to the central control module. The central control module can obtain the amount of biogas in the tank 11 in real time, and control the operation based on the monitoring information of the level monitoring device, thereby realizing the rational planning and efficient management of biogas use.

[0029] Optionally, the anaerobic digester system capable of real-time monitoring of biogas volume provided in this embodiment of the present invention includes a level monitoring device comprising a monitoring element 21 and a mounting bracket 22. The mounting bracket 22 serves as a support structure for the monitoring element 21, which is mounted on the outer wall of the tank 11 via the mounting bracket 22. During use, the monitoring element 21 cooperates with the load block 13, and the position of the load block 13 is monitored by the monitoring element 21 to obtain the level information of the gasbag 12.

[0030] The anaerobic reactor system provided in this embodiment of the invention, capable of real-time monitoring of biogas volume, further includes a guide pipe 14. The guide pipe 14 is disposed outside the tank body 11 and is vertically arranged. The guide pipe 14 supports the load block 13. Specifically, the load block 13 is slidably disposed on the guide pipe 14, and when the position of the air bladder 12 moves, the load block 13 slides synchronously on the guide pipe 14. Preferably, the aforementioned mounting bracket 22 is disposed on the guide pipe 14, thereby facilitating the cooperation between the monitoring element 21 and the load block 13. Moreover, the mounting bracket 22 is located above the load block 13, and correspondingly, the monitoring element 21 is also located above the load block 13, thereby improving the accuracy of the monitoring results of the monitoring element 21.

[0031] Preferably, the anaerobic digester system capable of real-time monitoring of biogas volume provided in this embodiment of the present invention includes a mounting bracket 22 comprising a clamp and a first mounting plate. The clamp matches the guide tube 14, and the first mounting plate is welded to the clamp. During assembly, the clamp is clamped onto the guide tube 14, and the monitoring component 21 is then fixed to the first mounting plate by riveting, screwing, or welding.

[0032] The anaerobic digester system for real-time monitoring of biogas volume provided in this embodiment of the present invention includes a laser rangefinder 211 as an optional embodiment of the monitoring component 21, which has high accuracy. When the monitoring component 21 is a laser rangefinder 211, the level monitoring device also includes a reflector 213 that cooperates with the laser rangefinder 211. The reflector 213 is fixedly mounted on the load block 13. The laser rangefinder 211 has a transmitting end. The laser emitted by the transmitting end of the laser rangefinder 211 hits the reflector 213 and can be reflected back to the transmitting end of the laser rangefinder 211. That is, the airbag 12 level monitoring device based on the laser rangefinder 211 provided in this embodiment obtains the level of the airbag 12 in the tank 11 by monitoring the position of the load block 13 through the cooperation of the laser rangefinder 211 and the reflector 213 mounted on the load block 13.

[0033] Preferably, in this embodiment, the level monitoring device further includes a second mounting plate 214, which serves as a support structure for the reflector 213. The reflector 213 can be mounted on the second mounting plate 214 to improve its stability. A planar mounting surface is provided on the load-bearing block 13. One side of the second mounting plate 214 is fixedly connected to the mounting surface by a first fastener such as a screw, rivet, or wire. The reflector 213 is fixed to the side of the second mounting plate 214 facing away from the mounting surface by a second fastener such as a screw or rivet. With the action of the second mounting plate 214, the reflector 213 has higher mounting strength. Compared to directly mounting the reflector 213 onto the load-bearing block 13, it is unnecessary to create excessive structures on the reflector 213 to cooperate with the load-bearing block 13, thus avoiding interference with its cooperation with the laser rangefinder sensor 211.

[0034] As a preferred embodiment of the present invention, the airbag 12 level monitoring device based on laser ranging is further provided with adhesive between the reflector 213 and the second mounting plate 214 to improve the connection strength between the reflector 213 and the second mounting plate 214 and improve reliability.

[0035] In other alternative embodiments, the laser rangefinder 211 can also be connected to the outer wall of the tank 11. In this embodiment, the mounting bracket 22 includes a first frame 221, a second frame 222, and a third frame 223. The first frame 221 and the second frame 222 are both plate-shaped structures. The first frame 221 and the second frame 222 are respectively disposed at both ends of the third frame 223. The third frame 223 is a rod-shaped structure. The first frame 221 is fixed to the outer wall of the tank 11 by screws or rivets, and the laser rangefinder 211 is fixed to the second frame 222 by screws or rivets.

[0036] Preferably, the first frame 221 and the third frame 223 can rotate relative to each other, or the second frame 222 and the third frame 223 can rotate relative to each other, or both the first frame 221 and the third frame 223 and the second frame 222 and the third frame 223 can rotate relative to each other. Through this arrangement, the angle of the laser rangefinder 211 can be adjusted so that the emitting end of the laser rangefinder 211 is aligned with the reflector 213. For example, when the second frame 222 and the third frame 223 can rotate relative to each other, a rotating seat 224 can be provided on the second frame 222, and the third frame 223 is rotatably connected to the rotating seat 224. The rotating seat 224 has a limiting self-locking function to fix the third frame 223 after it rotates a preset angle.

[0037] In this embodiment, the laser rangefinder 211 is provided with a connecting frame 225, which can be fixedly connected to the second frame 222 by screws or other structures.

[0038] In another optional embodiment of the anaerobic reaction system capable of real-time monitoring of biogas volume provided by this utility model embodiment, the monitoring component 21 is a pull-rope displacement sensor 212. Specifically, the pull-rope displacement sensor 212 includes a sensor body 2121 and a pull rope 2122. One end of the pull rope 2122 is connected to the sensor body 2121. The sensor body 2121 includes a shell, a measuring wheel, an encoder, a reset mechanism, and an electronic control module, etc. The other end of the pull rope 2122 is connected to the load block 13. During use, when the position of the airbag 12 changes and the position of the load block 13 changes synchronously with the airbag 12, the sensor body 2121 obtains the position of the airbag 12 based on the change in the extension of the pull rope 2122.

[0039] Preferably, a connecting buckle 215 is provided on the weight block 13. The connecting buckle 215 is used to connect to the pull rope 2122 of the pull rope displacement sensor 212. Specifically, the end of the pull rope 2122 away from the sensor body 2121 can be connected to the connecting buckle 215 by binding. By providing the connecting buckle 215 on the weight block 13 to connect with the pull rope 2122, the structure is stable, preventing the pull rope 2122 from separating from the weight block 13 due to external influences.

[0040] Preferably, in this embodiment, the connecting buckle 215 can be formed by binding metal wire to the load-bearing block 13. This eliminates the need to change the existing structure of the load-bearing block 13, and the metal binding method used to form the connecting buckle 215 results in a simple structure, low cost, and convenient maintenance and replacement. The metal wire can be iron wire, copper wire, or stainless steel wire, etc.

[0041] Alternatively, in other embodiments, the connecting buckle 215 described above can also be a ring-shaped structure, which is set on the load block 13 by means of screwing or welding, and can also achieve the purpose of connecting the load block 13 and the pull rope 2122.

[0042] In another connection method between the pull rope 2122 and the load block 13, a threaded hole is provided on the load block 13. A connecting bolt matching the threaded hole is fixedly provided at the end of the pull rope 2122 away from the sensor body 2121, and the connecting bolt is screwed into the threaded hole. The pull rope 2122 and the load block 13 are connected by the connecting bolt and the threaded hole, which has strong structural stability and is convenient for assembly.

[0043] Preferably, in this embodiment, a protective cap is also provided at the threaded hole to provide a waterproof seal for the connecting bolt and the threaded hole, preventing corrosion of the connecting bolt and the threaded hole after long-term use and making disassembly difficult during later inspection and maintenance. Specifically, the load-bearing block 13 is provided with a cylindrical ridge, and the threaded hole is opened on the ridge. The outer side of the ridge is provided with external threads. The protective cap is an open structure at one end, and its interior is provided with internal threads that match the external threads on the ridge. The protective cap is screwed onto the ridge. The other end of the protective cap is provided with a through hole, through which the pull rope 2122 can pass and be connected to the connecting bolt. During assembly, after the pull rope 2122 is inserted into the through hole, sealant can be applied to the through hole for sealing.

[0044] In this embodiment, the first mounting plate has an L-shaped cross-section and includes a horizontal plate and a vertical plate. Of the two adjacent sides of the horizontal plate, one side is welded to a clamp, and the other side is fixedly connected to the vertical plate. The vertical plate and the horizontal plate can be welded together or integrally formed. The horizontal plate has several through holes, and the sensor body 2121 is fixed to the horizontal plate by screws engaging with these through holes.

[0045] Preferably, the anaerobic digester system for real-time monitoring of biogas volume provided in this embodiment of the invention features a level monitoring device electrically connected to the central control module via a wireless transmission module, making it convenient to use. In other embodiments, the level monitoring device and the central control module can also be electrically connected via wired means such as optical fiber.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
