[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.

[0036] 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.

[0037] like Figure 1 and Figure 2 As shown, one embodiment of this utility model provides an airbag level monitoring device based on rope distance measurement, which is applied to an anaerobic reactor to monitor the level of the airbag 12 in the anaerobic reactor. The anaerobic reactor includes a tank 11, an airbag 12, and a weight block 13; the airbag 12 is disposed inside the tank 11 and located at the top of the tank 11, and the airbag 12 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 airbag 12 by a connector such as a steel wire rope. It should be noted that multiple weight blocks 13 are provided, and multiple weight blocks 13 are all connected to the airbag 12 and are arranged sequentially at intervals along the circumference of the airbag 12; the weight block 13 is used to pull the airbag 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 airbag 12 to move upward against the pulling force of the weight block 13.

[0038] The aforementioned airbag level monitoring device based on pull-string distance measurement includes a pull-string displacement sensor 21 and a mounting bracket 22. The mounting bracket 22 is the supporting structure for the pull-string displacement sensor 21. One end of the mounting bracket 22 is connected to the outer wall of the tank 11, and the pull-string displacement sensor 21 is installed at the end of the mounting bracket 22 away from the outer wall of the tank 11. Specifically, the pull-string displacement sensor 21 includes a sensor body 211 and a pull-string 212. One end of the pull-string 212 is connected to the sensor body 211. The sensor body 211 includes a shell, a measuring wheel, an encoder, a reset mechanism, and an electronic control module, etc. The other end of the pull-string 212 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 211 obtains the level of the airbag 12 based on the change in the extension of the pull-string 212.

[0039] The airbag level monitoring device based on rope distance measurement provided in this embodiment uses a rope displacement sensor 21 in conjunction with a load block 13 to obtain the level information of the airbag 12 by monitoring the position of the load block 13. The rope displacement sensor 21 has a high degree of automation and can realize real-time monitoring of the amount of biogas in the tank 11, so as to realize the rational planning and efficient management of biogas use.

[0040] Optionally, the airbag level monitoring device based on rope distance measurement provided in this embodiment of the present invention has a connecting buckle 131 on the weight block 13. The connecting buckle 131 is used to connect to the rope 212 of the rope displacement sensor 21. Specifically, the end of the rope 212 away from the sensor body 211 can be connected to the connecting buckle 131 by binding. By setting the connecting buckle 131 on the weight block 13 to connect to the rope 212, its structure is stable, preventing the rope 212 from separating from the weight block 13 due to external influences.

[0041] Preferably, in this embodiment, the connecting buckle 131 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 131 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.

[0042] Alternatively, in other embodiments, the connecting buckle 131 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 212.

[0043] In another connection method between the pull rope 212 and the load block 13, a threaded hole is provided on the load block 13, and a connecting bolt matching the threaded hole is fixedly provided at the end of the pull rope 212 away from the sensor body 211. The connecting bolt is screwed into the threaded hole. The pull rope 212 and the load block 13 are connected by the matching of the connecting bolt and the threaded hole, which has strong structural stability and is convenient for assembly.

[0044] 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 212 can pass and be connected to the connecting bolt. During assembly, after the pull rope 212 is inserted into the through hole, sealant can be applied to the through hole for sealing.

[0045] Optionally, in the airbag level monitoring device based on rope distance measurement provided in this embodiment of the present invention, a vertically arranged guide tube 14 is also connected to the outer wall of the tank 11, and the load block 13 is slidably disposed on the guide tube 14. The aforementioned mounting bracket 22 is fixedly disposed on the guide tube 14, and the mounting bracket 22 needs to be set higher than the load block 13, so that the rope displacement sensor 21 can be located above the load block 13, thereby improving the monitoring accuracy of the rope displacement sensor 21.

[0046] Optionally, in the airbag level monitoring device based on rope distance measurement provided in this embodiment of the present invention, the mounting bracket 22 includes a clamp and a mounting plate. The mounting plate is welded to the clamp, and the clamp can be mounted on the guide tube 14. The sensor body 211 of the rope displacement sensor 21 is fixedly mounted on the mounting plate. The mounting bracket 22 is formed by the clamp and the mounting plate, which has a simple structure and is easy to install. At the same time, since the clamp is compatible with the guide tube 14 of the existing anaerobic reactor, there is no need to change the structure of the existing anaerobic reactor.

[0047] Optionally, in other embodiments, the mounting bracket 22 can also be welded to the outer wall of the tank 11, which can also achieve the purpose of supporting the rope displacement sensor 21.

[0048] Optionally, in the airbag level monitoring device based on rope distance measurement provided in this embodiment of the present invention, the 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 211 is fixed to the horizontal plate by screws engaging with these through holes.

[0049] Optionally, the airbag level monitoring device based on rope distance measurement provided in this embodiment of the present invention also includes a signal transmission device. The signal transmission device is used to realize the signal transmission between the rope displacement sensor 21 and the central control unit. The signal transmission device can be an optical fiber or a wireless transmission module. Through the signal transmission device, the level information of the airbag 12 monitored by the rope displacement sensor 21 can be fed back to the central control unit in the control room, so that the operator can obtain the level information of the airbag 12.

[0050] Typically, the plant area is equipped with multiple anaerobic reactors, each of which is equipped with the aforementioned airbag level monitoring device based on rope distance measurement. The airbag level monitoring device based on rope distance measurement feeds back the airbag 12 level information of the corresponding anaerobic reactor to the central control computer in the control room through signal transmission equipment.

[0051] Another embodiment of this utility model provides an anaerobic reactor, including the airbag level monitoring device based on rope distance measurement as described in any of the above embodiments.
