Description

Technical Field

[0001] This utility model relates to the field of environmental protection equipment technology, specifically to an anaerobic reactor. Background Technology

[0002] An anaerobic reactor is a biochemical device that decomposes organic matter into methane and carbon dioxide under anaerobic conditions using microorganisms (such as acid-producing bacteria and methanogens). It is mainly used for wastewater treatment and energy recovery. Its core principle includes four stages: hydrolysis, acidification, acetic acid production, and methanogenesis. It is suitable for treating high-concentration organic wastewater and has advantages such as low energy consumption and biogas production.

[0003] Traditional anaerobic reactors rely on natural biogas to boost flow rates, which are relatively low and can easily lead to sludge bed compaction, insufficient contact between microorganisms and pollutants, and a lack of rapid dilution mechanisms when influent concentration or volume changes, which may cause a decline in microbial activity or even system collapse. Utility Model Content

[0004] The purpose of this invention is to provide an anaerobic reactor to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: An anaerobic reactor includes an anaerobic reactor body, an inlet pipe fixedly connected to the outer wall near the bottom of the anaerobic reactor body, an outlet pipe fixedly connected to the top of the anaerobic reactor body, a biogas discharge pipe fixedly connected to the center of the top of the anaerobic reactor body, a forced circulation mechanism provided on the anaerobic reactor body, and a convenient sampling mechanism and a temperature compensation mechanism provided on the forced circulation mechanism. The forced circulation mechanism includes a first branch pipe, a second branch pipe, and a circulation pump. The first branch pipe is fixedly connected to the outer wall of the anaerobic reactor body, and an annular pipe is fixedly connected to the end of the first branch pipe. The second branch pipe is fixedly connected to the outer wall of the anaerobic reactor body, and an annular pipe is fixedly connected to the end of the second branch pipe. The circulation pump is fixedly installed on the outer wall of the anaerobic reactor body, and an output pipe and an input pipe are fixedly connected to the circulation pump. The output pipe is fixedly connected to the bottom of the first annular pipe, and the input pipe is fixedly connected to the top of the second annular pipe.

[0006] Preferably, the convenient sampling mechanism includes a square tube, with a valve one fixedly connected to the top of the square tube and a valve two fixedly connected to the bottom of the square tube. The valve one and valve two are fixedly connected to the middle of the output tube, and a sampling valve is fixedly connected to the outer wall of the square tube.

[0007] Preferably, a movable cover is movably inserted into the outer wall of the square tube, and a transparent plate is fixedly installed on the inner wall of the movable cover.

[0008] Preferably, a frame is fixedly installed on the outer wall of the square tube, and a crossbar is detachably connected to the inner cavity of the frame.

[0009] Preferably, the temperature compensation mechanism includes a heating chamber, which is fixedly connected to the middle of the input pipe and fixedly installed on the outer wall of the anaerobic reactor body. A controller is fixedly installed on the outer wall of the heating chamber.

[0010] Preferably, a partition is fixedly installed on the inner wall of the heating chamber, and an electric heating component is fixedly installed on the inner wall of the heating chamber.

[0011] Preferably, a circular cover is detachably connected to the outer wall of the heating chamber, and a temperature sensor is fixedly installed on the circular cover. The temperature measuring end of the temperature sensor is located in the inner cavity of the heating chamber.

[0012] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows: Through the design of the forced circulation mechanism, when the circulation pump is running, it can draw liquid from the inside of the anaerobic reactor body from the second branch pipe, and then transport it back to the inner cavity of the anaerobic reactor body from the first branch pipe. This allows the liquid to circulate internally, increasing the liquid's own flow rate and enabling the granular sludge bed to fully expand. This increases the contact area between wastewater and microorganisms, avoids dead zones and short-circuiting in the reactor, and the forced circulation can quickly dilute fluctuations in influent concentration, reducing the inhibition of microorganisms by water quality shocks. It is especially suitable for high-concentration wastewater and improves the water treatment effect. Attached Figure Description

[0015] The present invention will be further described in detail below with reference to embodiments: like Figures 1-4 As shown, this utility model provides an anaerobic reactor, including an anaerobic reactor body 1. An inlet pipe 11 is fixedly connected to the outer wall of the anaerobic reactor body 1 near the bottom. An outlet pipe 12 is fixedly connected to the top of the anaerobic reactor body 1. A biogas discharge pipe 13 is fixedly connected to the center of the top of the anaerobic reactor body 1. A forced circulation mechanism 2 is provided on the anaerobic reactor body 1. A convenient sampling mechanism 3 and a temperature compensation mechanism 4 are provided on the forced circulation mechanism 2. The forced circulation mechanism 2 includes a branch pipe 21, a branch pipe 23, and a circulation pump 25. Branch pipe 21 is fixedly connected to the outer wall of the anaerobic reactor body 1, and an annular pipe 22 is fixedly connected to the end of branch pipe 21. Branch pipe 23 is fixedly connected to the outer wall of the anaerobic reactor body 1, and an annular pipe 24 is fixedly connected to the end of branch pipe 23. The circulation pump 25 is fixedly installed on the outer wall of the anaerobic reactor body 1, and an output pipe 26 and an input pipe 27 are fixedly connected to the circulation pump 25. The output pipe 26 is fixedly connected to the bottom of the annular pipe 22, and the input pipe 27 is fixedly connected to the top of the annular pipe 24. By controlling the operation of the circulation pump 25, liquid inside the anaerobic reactor body 1 can be absorbed from branch pipe 23. The liquid will pass through annular pipe 24, input pipe 27, and output pipe 26 into the interior of annular pipe 22, and then be transported from branch pipe 21 to the inner cavity of the anaerobic reactor body 1, promoting internal circulation of the liquid, increasing the liquid's own flow rate, and thus improving the reaction effect.

[0016] Furthermore, such as Figure 2 As shown, the convenient sampling mechanism 3 includes a square tube 31. A valve 32 is fixedly connected to the top of the square tube 31, and a valve 33 is fixedly connected to the bottom of the square tube 31. The valves 32 and 33 are fixedly connected to the middle of the output pipe 26. A sampling valve 34 is fixedly connected to the outer wall of the square tube 31. When the forced circulation mechanism 2 is running, the liquid inside the anaerobic reactor body 1 will flow through the inner cavity of the square tube 31. If sampling and testing are required, the valves 32 and 33 are closed first, and then the sampling valve 34 can be opened to discharge the liquid inside the square tube 31. The user can receive the liquid using a container, thus realizing the sampling function.

[0017] Furthermore, such as Figure 3As shown, a movable cover 35 is movably inserted into the outer wall of the square tube 31, and a transparent plate 36 is fixedly installed on the inner wall of the movable cover 35. The design of the transparent plate 36 makes it easy for users to observe the state of the liquid flowing inside the square tube 31, which facilitates production. During maintenance, the movable cover 35 can be pulled out from the square tube 31, and then the inside of the transparent plate 36 can be cleaned. A rubber ring is fitted on the outer wall of the movable cover 35 to seal the connection between the movable cover 35 and the square tube 31.

[0018] Furthermore, such as Figure 3 As shown, a frame 37 is fixedly installed on the outer wall of the square tube 31. A crossbar 38 is detachably connected to the inner cavity of the frame 37. Bolts are provided on the frame 37. In the initial state, the bolts are tightened and used to fix the crossbar 38 inside the frame 37. The frame 37 is used to limit the movable cover 35 on the square tube 31. If it is necessary to remove the movable cover 35, loosen the bolts on the frame 37, and then pull out the crossbar 38, and then the movable cover 35 can be removed.

[0019] Furthermore, such as Figure 4 As shown, the temperature compensation mechanism 4 includes a heating chamber 41, which is fixedly connected to the middle of the input pipe 27. The heating chamber 41 is fixedly installed on the outer wall of the anaerobic reactor body 1. A controller 44 is fixedly installed on the outer wall of the heating chamber 41. When the forced circulation mechanism 2 is running, the liquid inside the anaerobic reactor body 1 will flow through the inner cavity of the heating chamber 41.

[0020] Furthermore, such as Figure 4 As shown, a partition 42 is fixedly installed on the inner wall of the heating chamber 41, and an electric heating element 43 is fixedly installed on the inner wall of the heating chamber 41. The operation of the electric heating element 43 can heat the liquid circulating inside the heating chamber 41. Through the design of the partition 42, the liquid inside the heating chamber 41 can be guided to improve the full contact between the liquid and the electric heating element 43.

[0021] Furthermore, such as Figure 4As shown, a circular cover 45 is detachably connected to the outer wall of the heating chamber 41. A temperature sensor 46 is fixedly installed on the circular cover 45. The temperature measuring end of the temperature sensor 46 is located in the inner cavity of the heating chamber 41. Through the design of the temperature sensor 46, the temperature of the circulating liquid can be monitored and the temperature data can be fed back to the controller 44. When the temperature is lower than the preset value, the controller 44 immediately controls the electric heating component 43 to work, heating the solution and raising the temperature of the solution. Because the activity of microorganisms is severely limited below 20°C, resulting in a poor reaction effect, this design can ensure the reaction effect of the solution. The circular cover 45 is installed on the outer wall of the heating chamber 41 by bolts. During maintenance, the temperature sensor 46 can be removed by removing the circular cover 45, and the user can then perform temperature measurement on the temperature measuring end of the temperature sensor 46. Regarding cleanliness, it is worth noting that the electric heating component 43, controller 44, and temperature sensor 46 in this solution are commercially available devices that can be purchased by those skilled in the art. No structural modifications have been made to these devices in this paper. Therefore, those skilled in the art are familiar with their working principles based on their professional knowledge and can apply them proficiently. Thus, this paper will not elaborate further on this aspect. Furthermore, this solution aims to protect the physical structure, but does not provide protection for the circuitry and software control. The mention of the processing circuit in this paper is merely a supplementary explanation of the feasibility and authenticity of this utility model. This utility model does not require protection for the algorithm and circuitry technology. It is worth emphasizing that although this solution does not elaborate on the electronic control program, those skilled in the art can be familiar with and apply it based on their professional knowledge.

[0022] The working principle of this anaerobic reactor will be explained in detail below.

[0023] like Figures 1-4 As shown, during use, the circulating pump 25 is operated to absorb liquid from the anaerobic reactor body 1 through branch pipe 23. The liquid passes through annular pipe 24, input pipe 27, and output pipe 26 into the interior of annular pipe 22, and then is transported from branch pipe 21 to the inner cavity of the anaerobic reactor body 1, promoting internal circulation of the liquid, increasing the liquid's own flow rate, and thus improving the reaction effect. If sampling is required, valve 1 32 and valve 2 33 are closed first, and then sampling valve 34 is opened to discharge the liquid inside square pipe 31. The user uses a container to receive the liquid, thus realizing the sampling function. Temperature sensor 46 is used to monitor the temperature of the circulating liquid and feeds the temperature data back to controller 44. When the temperature is lower than the preset value, controller 44 immediately controls electric heating component 43 to work to heat the solution, realizing the temperature compensation function.

[0024] It should be noted that, in the description of this disclosure, unless otherwise expressly specified and limited, the terms "installation," "connection," and "joint" 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; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure according to the specific circumstances.

[0025] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
