Description

Technical Field

[0001] This application relates to the technical field of uniform gas dispensing devices, and more particularly to a disc-type device for uniform gas dispensing. Background Technology

[0002] Biogas engineering technology is a rural energy engineering technology that utilizes manure to obtain energy and control environmental pollution, aiming to achieve a virtuous cycle of agriculture and ecology. In biogas engineering, the principle behind methane production is primarily anaerobic digestion. Anaerobic digestion is a complex reaction process involving multiple microorganisms. During anaerobic digestion, organic matter (such as agricultural waste and livestock manure) is decomposed into simpler compounds through a series of biochemical reactions in the oxygen-deficient conditions within the biogas digester.

[0003] In the methanogenesis stage, methanogenic bacteria utilize hydrogen and carbon dioxide as substrates to produce methane gas. This is a crucial step in anaerobic digestion. Hydrogenophilic bacteria play an important role in methanogenesis. They are able to utilize hydrogen and carbon dioxide as substrates to carry out fermentation reactions under anaerobic conditions to produce methane gas.

[0004] However, since hydrogenophilic bacteria require a certain concentration of hydrogen as an energy source, and the solubility and diffusion rate of hydrogen are limited, their distribution in the reaction system is uneven. Therefore, when using hydrogenophilic bacteria to produce methane gas, conventional hydrogen input methods are prone to uneven hydrogen addition. Summary of the Invention

[0005] This application addresses the shortcomings of existing technologies by providing a disc-type device for uniform gas sampling. By designing a gas pipeline assembly, it achieves the effect of uniform gas sampling (including gas flow rate and velocity).

[0006] The technical solution to the above-mentioned technical problems in this application is as follows:

[0007] A disc-type device for uniform gas sampling includes a gas sampling mechanism disposed at the bottom of a biogas tank. The gas sampling mechanism includes an inlet main pipe, a first gas delivery pipe, a second gas delivery pipe, a third gas delivery pipe, a fourth gas delivery pipe, and an outlet pipe. The inlet main pipe is connected to the bottom ends of the plurality of first gas delivery pipes. The top end of each first gas delivery pipe is connected to the bottom ends of two second gas delivery pipes. The top end of each second gas delivery pipe is connected to the bottom ends of two third gas delivery pipes. The top end of each third gas delivery pipe is connected to the bottom ends of two fourth gas delivery pipes. The top end of each fourth gas delivery pipe is connected to the bottom ends of two outlet pipes. The input gas enters the biogas tank sequentially through the inlet main pipe, the first gas delivery pipe, the second gas delivery pipe, the third gas delivery pipe, the fourth gas delivery pipe, and the outlet pipe.

[0008] By adopting the above technical solution, when gas is introduced into the biogas digester, the gas sequentially passes through the main inlet pipe, the first gas delivery pipe, the second gas delivery pipe, the third gas delivery pipe, the fourth gas delivery pipe, and the outlet pipe before entering the biogas tank. Multiple outlet pipes disperse the gas outlet positions, thereby allowing the gas to enter the biogas digester more evenly and achieving a uniform gas distribution effect. The arrangement of the main inlet pipe, the first gas delivery pipe, the second gas delivery pipe, the third gas delivery pipe, the fourth gas delivery pipe, and the outlet pipe ensures uniform gas distribution while saving transport space and improving transport efficiency.

[0009] Furthermore, a support plate for supporting the fourth gas pipeline is provided below the biogas tank. The biogas tank is connected to the support plate via a support rod, and multiple support plates are arranged radially along the biogas tank.

[0010] Furthermore, the support plate is fan-shaped.

[0011] Furthermore, the air outlets of the air outlet pipe are arranged sequentially along the length of the support plate.

[0012] Furthermore, the diameter of the air outlet of the air outlet pipe gradually increases in the direction away from the support rod.

[0013] Furthermore, the area of ​​the gas outlet of the gas pipe is proportional to the distance between the central axis of the gas pipe and the central axis of the biogas tank.

[0014] Furthermore, the first gas supply pipe is provided with sixteen sections.

[0015] Furthermore, the biogas tank includes a base plate and a tank body, which are rotatably connected.

[0016] Furthermore, the inner wall of the tank is provided with a scraper, which is slidably connected to the bottom plate of the biogas tank when the bottom plate rotates.

[0017] Furthermore, the outlet of the air outlet pipe is equipped with a filter screen.

[0018] In summary, compared with the prior art, the beneficial effects of the above technical solution are:

[0019] The disc-type device for uniform gas dispensing described in this application, when introducing gas into a biogas digester, the gas sequentially passes through the main inlet pipe, the first gas delivery pipe, the second gas delivery pipe, the third gas delivery pipe, the fourth gas delivery pipe, and the outlet pipe into the biogas tank. Multiple outlet pipes disperse the gas outlet positions, thereby allowing the gas to enter all parts of the biogas digester more evenly, achieving a uniform gas dispensing effect. The arrangement of the main inlet pipe, the first gas delivery pipe, the second gas delivery pipe, the third gas delivery pipe, the fourth gas delivery pipe, and the outlet pipe ensures uniform gas dispensing while saving transport space and improving transport efficiency.

[0024] The principles and features of this application are described below with reference to the accompanying drawings. The examples given are only for explaining this application and are not intended to limit the scope of this application.

[0025] This application discloses a disc-type device for uniformly dispensing gas.

[0026] Reference Figures 1-3 A disc-type device for uniform gas sampling includes a gas sampling mechanism disposed at the bottom of a biogas tank 1. The gas sampling mechanism includes an inlet manifold 2, a first gas delivery pipe 3, a second gas delivery pipe 4, a third gas delivery pipe 5, a fourth gas delivery pipe 6, and an outlet pipe 7. The inlet manifold 2 is connected to the bottom ends of the multiple first gas delivery pipes 3. The top ends of the first gas delivery pipes 3 are connected to the bottom ends of the two second gas delivery pipes 4. The top ends of the second gas delivery pipes 4 are connected to the bottom ends of the two third gas delivery pipes 5. The top ends of the third gas delivery pipes 5 are connected to the bottom ends of the two fourth gas delivery pipes 6. The top ends of the fourth gas delivery pipes 6 are connected to the bottom ends of the two outlet pipes 7. The input gas enters the biogas tank 1 sequentially through the inlet manifold 2, the first gas delivery pipe 3, the second gas delivery pipe 4, the third gas delivery pipe 5, the fourth gas delivery pipe 6, and the outlet pipe 7.

[0027] When gas is introduced into the biogas digester, the gas passes sequentially through the main inlet pipe 2, the first gas delivery pipe 3, the second gas delivery pipe 4, the third gas delivery pipe 5, the fourth gas delivery pipe 6, and the outlet pipe 7 into the biogas tank 1. The gas in the main inlet pipe 2 disperses into multiple first gas delivery pipes 3, then sequentially enters two second gas delivery pipes 4 connected to the first gas delivery pipes 3, then sequentially enters two third gas delivery pipes 5 connected to the second gas delivery pipes 4, then sequentially enters two fourth gas delivery pipes 6 connected to the third gas delivery pipes 5, and finally sequentially enters two outlet pipes 7 connected to the fourth gas delivery pipes 6 and is introduced into the biogas tank 1.

[0028] The main inlet pipe 2, the first gas delivery pipe 3, the second gas delivery pipe 4, the third gas delivery pipe 5, the fourth gas delivery pipe 6, and the outlet pipe 7 work together to evenly distribute the gas, making it easier to control the gas flow rate and velocity. The multiple outlet pipes 7 disperse the gas outlet positions, thereby enabling the gas to enter the biogas digester more evenly and achieve a uniform gas addition effect. That is, under ideal conditions, the gas outlet rate and gas volume at each position on the plate are equal.

[0029] The first gas supply pipe 3 has sixteen outlets. The diameter of the outlet of the gas pipe 7 gradually increases from the inside to the outside. The area of ​​the outlet of the gas pipe 7 is proportional to the distance between the central axis of the gas pipe 7 and the central axis of the biogas tank 1. When gas is introduced into the biogas digester, in order to ensure that the gas output rate and output volume at each point are the same as much as possible, it is necessary to ensure that the number of gas outlets on different circumferences is the same. Therefore, the total gas output (Q) on different circumferences (C) is proportional to the distance (R) from the center of the outlet of the gas pipe 7 to the center of the biogas tank 1. Therefore, the gas output (q) of the gas outlets on different circumferences is proportional to the total gas output on different circumferences. Since q = vs and v is equal, the area of ​​the outlet of the gas pipe 7 is proportional to R.

[0030] Specifically, Q is the total air volume on different circumferences (C), Q / 16 = q, q is the air volume of the 16 outlets on different circumferences, v is the air velocity. When this device is set up, the diversion method adopted at the connection is to ensure that the air velocity (v) at the outlet is the same. s is the area of ​​the outlet. For example, the total air volume Q of the outermost ring is 800, so the air volume q of each outlet on the outermost ring is 50, and v*s = 50 at each outlet on the outermost ring.

[0031] Below the biogas tank 1 is a support plate 8 for supporting the fourth gas transmission pipe 6. The biogas tank 1 is connected to the support plate 8 via a support rod 10. Multiple support plates 8 are arranged radially along the biogas tank 1. The support plates 8 are fan-shaped. Multiple fan-shaped support plates 8 are arranged in a circular pattern, such as... Figure 2 As shown. The gas outlets of the gas outlet pipe 7 are arranged sequentially along the length of the support plate 8. The support plate 8 can stably support the gas outlet pipe 7 at the bottom of the biogas tank 1.

[0032] The biogas digester 1 includes a base plate 101 and a tank body 102, which are rotatably connected. A sealing ring is provided around the base plate 101 of the biogas digester 1. During gas input, the base plate 101 of the biogas digester 1 can rotate relative to the tank body 102. At this time, the gas outlet pipe 7 moves with the base plate 101, and the main gas inlet pipe 2, the first gas delivery pipe 3, the second gas delivery pipe 4, the third gas delivery pipe 5, and the fourth gas delivery pipe 6 rotate below the biogas digester 1. This allows the gas outlet pipe 7 to achieve a rotating ventilation function, thereby making the gas mix more evenly with the materials inside the biogas digester.

[0033] The inner wall of the tank 102 is provided with scrapers 9. When the bottom plate rotates, the scrapers 9 are slidably connected to the bottom plate 101 of the biogas tank 1. In this embodiment, multiple scrapers 9 are provided, all passing through the axis of the biogas tank 1. When the bottom plate 101 of the biogas tank 1 rotates relative to the side wall of the biogas tank 1, the scrapers 9 are stationary relative to the side wall of the biogas tank 1 on the inner wall of the biogas tank 1. At this time, the bottom end of the scrapers 9 is slidably connected to the bottom plate 101 of the biogas tank 1, thereby scraping away the material at the gas outlet of the gas outlet pipe 7 and stirring the material, which helps to prevent the gas outlet pipe 7 from being blocked and improves the mixing uniformity.

[0034] The outlet of the gas pipe 7 is equipped with a filter screen. The filter screen can effectively prevent the material conduit in the biogas tank 1 from flowing into the gas pipe 7, which helps to prevent the gas pipe 7 from becoming blocked.

[0035] The implementation principle of the disc-type device for uniform gas sampling in this application embodiment is as follows: When gas is introduced into the biogas digester, the gas passes through the main gas inlet pipe 2, the first gas delivery pipe 3, the second gas delivery pipe 4, the third gas delivery pipe 5, the fourth gas delivery pipe 6, and the gas outlet pipe 7 in sequence into the biogas tank 1. The multiple gas outlet pipes 7 disperse the gas outlet positions, thereby enabling the gas to enter the various positions of the biogas digester more evenly and achieving the effect of uniform gas sampling.

[0036] The above description is only a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
