Description

Technical Field

[0001] This utility model relates to the field of display device technology, and in particular to an anaerobic tank sampling and real-time monitoring device. Background Technology

[0002] Anaerobic digestion, as one of the most promising organic matter treatment technologies, utilizes the metabolic activity of naturally occurring anaerobic microorganisms under anaerobic conditions to convert various macromolecular organic matter into biogas and biogas residue. This technology is universally applicable to a wide variety of organic wastes and can be used to treat various types of organic waste, offering significant environmental and economic advantages. The anaerobic fermentation system is a complex system involving multiple microbial communities and multiple reactions. Various microorganisms exhibit both constraints and competition, as well as dependence and cooperation. Its internal homeostasis can be revealed through a series of detection data. Therefore, accurately detecting the characteristics of the raw materials in the anaerobic digester and providing accurate detection data is crucial for the continuous, stable, and efficient operation of the anaerobic system.

[0003] For example, patent number 201920649495.9, entitled "An Anaerobic Tank Sampling Device," specifically includes: a sampling tube disposed inside an anaerobic tank; and an outlet pipe connected to the sampling tube, the outlet pipe penetrating the tank wall of the anaerobic tank for leading the sample from the sampling tube to a predetermined position outside the anaerobic tank. The end of the outlet pipe is connected to a vent for venting residual material and a sampling port for sampling. This utility model provides an anaerobic tank sampling device that solves the problems of difficult anaerobic tank sampling operations and the risk of odor leakage and secondary environmental pollution during the sampling process, making sampling more convenient, faster, and safer.

[0004] Although the aforementioned patents have solved the problems of sampling difficulties in existing anaerobic tanks and odor leakage caused by waste liquid during the sampling process, some of the remaining liquid needs to be discharged during the sampling process in order to solve the problem of odor generated during the discharge process, which leads to the waste of raw materials. At the same time, for anaerobic tanks that treat wastewater with high solid content, the sampling tube is prone to frequent blockage. Utility Model Content

[0005] In view of this, in order to solve the problems of liquid waste and easy clogging of sampling tubes during the sampling process in the prior art, this utility model proposes an anaerobic tank sampling and real-time monitoring device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An anaerobic digester sampling and real-time monitoring device includes an anaerobic digester, a sampling tube disposed inside the anaerobic digester, the other end of the sampling tube passing through the anaerobic digester and connected to a collecting pipe, the outlet of the collecting pipe being connected to a sampling pump, the outlet of the sampling pump being connected to a measuring pipe, the outlet of the measuring pipe being connected to a return pipe, the other end of the return pipe being located inside the anaerobic digester, and a sampling port being disposed on the measuring pipe.

[0007] As a further improvement to the above technical solution: An optimized version of the above technical solution is that the ends of the multiple sampling tubes are connected to the collecting tube, and the multiple sampling tubes are at different heights inside the anaerobic tank.

[0008] An optimized version of the above technical solution is that each sampling tube is equipped with a first automatic valve.

[0009] An optimized version of the above technical solution is that each sampling tube is equipped with a first manual valve.

[0010] An optimized solution to the above technical solution is that a second automatic valve is provided on the return pipe.

[0011] An optimized solution to the above technical solution is to provide a second manual valve on the reflux pipe.

[0012] An optimized solution to the above technical solution is to provide a third manual valve on the sampling port.

[0013] An optimized version of the above technical solution is that a temperature sensor is installed on the measuring tube.

[0014] An optimized version of the above technical solution is that a pH meter is installed on the measuring tube.

[0015] An optimized version of the above technical solution is that a glass sight glass tube is provided on the measuring tube.

[0016] Compared with existing technologies, the beneficial effects of this utility model are: This invention employs a sampling pump combined with a reflux circulation pipeline, eliminating the need for pre-drainage of waste liquid during sampling. This significantly reduces odor generation and raw material waste during drainage. Simultaneously, the circulation pipeline allows for regular flushing, preventing the sampling pipeline from becoming clogged due to material buildup from prolonged inactivity.

[0017] This invention employs multiple sampling tubes arranged at different heights within the anaerobic tank according to requirements, thereby diversifying the sampled liquids and facilitating a clearer understanding of the internal conditions.

[0018] This invention features automatic valves at different pipeline locations, which improves the overall automation process and reduces manual operation. To prevent the automatic valves from malfunctioning, manual valves are also installed at the corresponding locations for easy intervention.

[0019] This invention is equipped with a pH meter and a temperature sensor, which facilitates the detection of temperature and pH, thereby allowing adjustment of the detection position (sampling tube at which height) and frequency according to needs. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In addition, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0024] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] like Figure 1 As shown, this solution targets anaerobic tank 1. Therefore, the main purpose of this technical solution is to extract liquid from anaerobic tank 1 for sampling and testing. Thus, the technical solution is described as follows: 1. Sampling tube 2, from the attached... Figure 1 and Figure 3 As can be seen, the sampling tube 2 is divided into two sections, which are connected in the middle by a flange. The flange is located on the side wall of the anaerobic tank 1. One section of the sampling tube 2 is inside the anaerobic tank 1. As can be seen from the attached figure, the four sampling tubes 2 inside the anaerobic tank 1 are not at the same horizontal height. This design is to collect liquid at different heights during the sampling process. The lower ends of the sampling tubes 2 located outside the anaerobic tank 1 are all connected to the collecting tubes 3. At the same time, each sampling tube 2 located outside the anaerobic tank 1 is equipped with a first manual valve 9 and a first automatic valve 8. The first manual valve 9 is in the normally open state. II. Sampling pump 4, as attached Figure 1 With appendix Figure 4 One end of the manifold 3 is blocked, and the other end is connected to the sampling pump 4. Thus, the liquid in the anaerobic tank 1 can be extracted by the action of the sampling pump 4. III. Measuring tube 5, as attached Figure 1 Appendix Figure 2 With appendix Figure 4 As shown, the measuring tube 5 is composed of multiple pipe sections connected by a flange. One end of the measuring tube 5 is connected to the outlet of the sampling pump 4. The middle of the measuring tube 5 is the data acquisition section, and a temperature sensor 14 and a pH meter 15 are installed above it. The temperature and pH of the liquid can be measured, which allows the user to adjust the acquisition frequency and acquisition height in a timely manner. At the rear end of the data acquisition section is a glass sight glass tube 16, which allows users to observe the flow of the medium inside the sampling tube 2. At the rear end of the glass sight glass tube 16 is a liquid collection section, and a sampling port 7 is provided on the liquid collection section. A third manual valve 12 is provided on the sampling port 7 for sampling the liquid. At the same time, the rear end of the sampling port 7 can be manually sampled and sent to the laboratory for testing, or it can be connected to other online analytical instruments.

[0026] IV. Return pipe 6, as attached Figure 1 With appendix Figure 4 As shown, the end of the return pipe 6 is connected to the end of the measuring pipe 5, and the other end is inserted into the anaerobic tank 1. A second automatic valve 10 and a second manual valve 11 are installed on the return pipe 6. The second manual valve 11 is in the normally open state, thus forming a circulating return pipeline.

[0027] The aforementioned automatic valve and sampling pump 4 can be remotely controlled by a computer, so a corresponding control box can be configured to improve automation.

[0028] The working process of this technical solution is as follows: When sampling is required, if a water sample needs to be taken from a certain height in the anaerobic tank 1, the first automatic valve 8, the sampling pump 4, and the second automatic valve 10 below the sampling pipe 2 at the corresponding height will be automatically activated via the on-site operation box. After a period of time, the sampling valve will be opened to take the sample. The first automatic valve 8, the second automatic valve 10, and the sampling pump 4 will automatically close after a delay. As a result, the waste liquid that would normally be discharged will flow back into the anaerobic tank 1 through the sampling pump 4, which also reduces the generation of odor sources.

[0029] When monitoring pH and temperature, the system operates according to the preset monitoring sampling points and frequencies in the automated control program. When monitoring is required at a certain location, the automated control program will open the corresponding automatic valve, the sampling pump 4, and the automatic valve at the end of the sampling tube 2. After running for a period of time, the monitored pH and temperature will be uploaded and recorded. Users can adjust the monitoring location and frequency according to their needs.

[0030] For sampling points with low monitoring frequency, the device will automatically start working once a day to prevent the sampling tubes from clogging due to internal material accumulation and affecting valve operation due to long-term disuse.

[0031] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
