Description

Technical Field

[0001] This utility model relates to the field of biogas desulfurization technology, specifically a device for temporary storage and recovery of desulfurization liquid samples for biogas desulfurization. Background Technology

[0002] Biogas desulfurization is a key environmental protection technology in fields such as food waste treatment, wastewater treatment, and biomass energy. It primarily removes hydrogen sulfide from biogas, preventing its corrosive effects on equipment and the environment. Currently, wet desulfurization is widely used in biogas desulfurization technology, which utilizes a desulfurization solution to absorb hydrogen sulfide. This technology typically requires sampling and testing of the desulfurization solution to ensure stable desulfurization performance. However, existing technologies have certain shortcomings in the sampling, storage, and recovery of the desulfurization solution.

[0003] Existing biogas desulfurization systems typically rely on manual sampling and recovery of samples. During sampling, the desulfurization liquid sample is often not recovered in a timely manner, and the recovery process is cumbersome. Due to the lack of automated recovery devices, the desulfurization liquid sample is often temporarily stored in containers, and prolonged storage can lead to liquid precipitation and crystallization, affecting its usability and thus reducing desulfurization efficiency. Furthermore, due to human error, the amount of sample recovered may not be accurately controlled, easily resulting in waste of desulfurization liquid and increasing the system's operating costs and management complexity. Utility Model Content

[0013] The present invention provides a temporary storage and recovery device for desulfurization liquid samples in biogas desulfurization, which has the following beneficial effects:

[0014] By rationally configuring the sample storage tank and the explosion-proof solenoid valve in an automatic control system, liquid recovery after sampling is achieved, and the desulfurization liquid can be efficiently recovered into the system, avoiding errors and waste caused by manual intervention.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0021] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0022] like Figures 1-3 As shown in the figure, the present invention provides a temporary storage and recovery device for desulfurization liquid samples for biogas desulfurization, including an emergency tank 1, the surface of which is provided with a support frame.

[0023] The surface of the support frame is provided with a sample storage tank 2, and the lower surface of the sample storage tank 2 is connected to a drain pipe 6, and an explosion-proof solenoid valve 5 is installed on the outside of the drain pipe 6.

[0024] A movable top cover 3 is movably connected to the upper surface of the sample storage tank 2.

[0025] In one embodiment of this utility model, this technical solution proposes a temporary storage and recovery device for desulfurization liquid samples in biogas desulfurization, which aims to improve the utilization efficiency of desulfurization liquid, reduce waste, and ensure the continuous stability of the desulfurization process by optimizing the temporary storage and recovery process of desulfurization liquid in the biogas desulfurization system.

[0026] The core structure of the device includes an emergency tank 1, a support frame, a sample storage tank 2, an explosion-proof solenoid valve 5, a drain pipe 6, and a movable top cover 3. These components work together to solve several problems in the temporary storage and recovery of desulfurization liquid samples.

[0027] During operation, the desulfurization liquid sample is first extracted from the biogas desulfurization system and temporarily stored in sample storage tank 2. Sample storage tank 2 is located on the surface of the support frame for convenient liquid storage and recovery. To prevent sample liquid spillage and loss, a drain pipe 6 is connected below the storage tank. An explosion-proof solenoid valve 5 installed on the outside of the drain pipe 6 intelligently controls liquid discharge, achieving timely recovery of the sample liquid through precise on / off control. Under the control of the explosion-proof solenoid valve 5, the desulfurization liquid sample can be guided into the emergency tank 1 according to preset requirements, ensuring that the liquid does not spill or waste during processing.

[0028] The upper surface of the sample storage tank 2 is equipped with a movable top cover 3. The top cover can be opened for liquid injection during use, and closed after use to prevent external impurities from entering. This design ensures the equipment's airtightness and ease of operation.

[0029] This device addresses the waste problem that occurs during the sampling of desulfurization liquid in biogas desulfurization systems. In existing technologies, desulfurization liquid samples often require manual transfer and recovery after sampling, a cumbersome process that easily leads to liquid waste. Through the intelligent control of the explosion-proof solenoid valve 5 and the movable top cover 3, users can more efficiently complete the temporary storage and recovery of samples without manual intervention, reducing operational difficulty and labor costs.

[0030] In terms of applications, this device is particularly suitable for biogas desulfurization systems, especially for treating biogas generated from organic waste such as kitchen waste. In these systems, the recovery of the desulfurization liquid not only helps reduce material waste but also extends its service life and maintains the stability of the desulfurization effect. By integrating sample storage and recovery functions, more refined and automated operation management can be achieved.

[0031] This technological solution has broad application prospects in the environmental protection field. With the increasing demand for desulfurization technology in industries such as waste treatment and wastewater treatment, this device can not only improve production efficiency but also reduce environmental pollution, meeting the needs of sustainable development. Furthermore, due to its simple structure, convenient operation, and relatively low installation and maintenance costs, it has high promotional value in practical applications.

[0032] In summary, this technical solution, through intelligent control and optimized design, solves the problems of waste and inefficiency in the storage and recovery of desulfurization liquid samples, improves the working efficiency of biogas desulfurization systems, and is of great significance for promoting the popularization and application of biogas desulfurization technology.

[0033] In this embodiment, a hinge 7 is installed on the surface of the sample storage tank 2, and the movable top cover 3 is rotatably connected to the top opening of the sample storage tank 2 via the hinge 7.

[0034] The movable top cover 3 is connected to the sample storage tank 2 via hinge 7, making the opening and closing of the top cover simpler. Operators can easily open and close the top cover, avoiding cumbersome disassembly or complex operations. The hinge connection also ensures the stability of the top cover when open, preventing it from completely falling off or shaking, thereby improving safety and convenience of use. In addition, this design ensures that the tank opening can be completely sealed, effectively preventing the desulfurization liquid from overflowing or contaminating, and maintaining the purity of the liquid inside the tank. The hinge connection also facilitates regular cleaning, reduces maintenance difficulty, and improves the hygiene and long-term stability of the equipment.

[0035] In this embodiment, a filter screen 4 is installed inside the sample storage tank 2, and the filter screen 4 is placed at the bend inside the sample storage tank 2.

[0036] The filter screen 4 installed inside the sample storage tank 2 effectively filters impurities in the desulfurization liquid. The filter screen 4 is positioned at the bend within the tank, ensuring full contact between the liquid and the screen as it passes through, thus preventing larger particles from entering the drain pipe 6. This design not only improves the purity of the desulfurization liquid and prevents impurities from clogging the system, but also simplifies equipment maintenance, as the screen can be easily disassembled and cleaned, ensuring long-term stable operation of the device.

[0037] like Figure 2 and Figure 3 As shown, in one embodiment of this utility model, a support rod 8 is connected to the inner bottom of the sample storage tank 2, and a hollow float 11 is sleeved on the outer side of the support rod 8. An adjusting block 9 is movably connected to the outer side of the support rod 8, and a pressure sensor 10 is mounted on the surface of the adjusting block 9. The adjusting block 9 is positioned above the hollow float 11. The top of the support rod 8 is lower than the lower surface of the filter screen 4. The pressure sensor 10 has an explosion-proof function.

[0038] In this embodiment of the present invention, the support rod 8 inside the sample storage tank 2, together with the hollow float 11, the adjusting block 9, and the pressure sensor 10, forms an automated control system for precisely controlling the amount of sample added. When the sample is added to the sample storage tank 2, buoyancy causes the hollow float 11 to rise. As the amount of liquid sample increases, the float 11 gradually rises. When the float 11 rises to a preset height, it contacts the adjusting block 9. The pressure sensor 10 on the adjusting block 9 detects this change and sends a signal to pause the sample addition process. This automated control can prevent over-injection of the sample and prevent liquid overflow or waste.

[0039] Furthermore, a scale can be set on the support rod 8, making changes in liquid level more intuitive. By observing the scale on the float 11 and the support rod 8, operators can monitor the liquid level in the sample storage tank in real time, further ensuring the accuracy of sample injection. The scale also facilitates system adjustment and calibration, increasing the ease of use and operability of the equipment.

[0040] This design solves the problems of inaccurate, excessive, or insufficient sample injection in traditional manual operations, improving the automation level of the liquid injection process and reducing human error. This automated control system allows for more precise management of sample input, ensuring that each operation meets preset requirements and enhancing the overall system's stability and reliability.

[0041] This technical solution is particularly suitable for fields requiring precise control of liquid dosage, such as biogas desulfurization. With the increasing adoption of automated control technology in the environmental protection industry, similar systems will be used more and more widely. By improving operational precision and reducing manual intervention, this device has a promising market prospect, especially in industrial applications requiring large-scale, long-term stable operation.

[0042] In this embodiment, an adjusting thread 12 is provided on one side of the surface of the support rod 8, and an adjusting thread hole is provided on the surface of the adjusting block 9. The adjusting block 9 is movably connected to the support rod 8 through the adjusting thread hole and the adjusting thread 12.

[0043] The adjusting thread 12 on the surface of the support rod 8 engages with the adjusting thread hole on the surface of the adjusting block 9. Through the movable connection between the adjusting thread 12 and the adjusting thread hole, the position of the adjusting block 9 on the support rod 8 can be adjusted.

[0044] The main purpose of this design is to provide a flexible adjustment mechanism, allowing users to adjust the position of the adjusting block 9 as needed, thereby precisely controlling the rising height of the hollow float 11. By rotating the adjusting block 9, users can change its position, thus altering the starting or stopping height of the hollow float 11 for liquid injection. This allows the system to be customized according to different liquid volume requirements or specific operating environments, ensuring accurate liquid injection.

[0045] The design of the adjusting thread not only improves the accuracy of the adjustment process but also facilitates fine-tuning of the system, adapting to different working conditions. Furthermore, the mobility of the adjusting block 9 makes the system more flexible in use, allowing for quick adjustments as needed, thereby enhancing the adaptability and operability of the equipment.

[0046] It should be noted that, in order to facilitate adjustment and ensure adjustment accuracy, the filter screen 4 needs to be removed during adjustment. This prevents the filter screen 4 from obstructing the movement of the adjusting block 9 and ensures a smooth adjustment process.

[0047] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
