Description

Technical Field

[0001] This invention relates to the field of anaerobic fermentation technology, specifically a novel completely mixed anaerobic reactor. Background Technology

[0002] Fermentation of livestock and poultry manure is a biological treatment technology that utilizes microorganisms to decompose organic matter, and it is widely used in agriculture and environmental protection. Livestock and poultry manure (feces, urine, livestock wastewater, etc.) contains a large amount of organic matter (such as protein, carbohydrates, fats, etc.), nutrients such as nitrogen, phosphorus, and potassium, as well as harmful substances such as pathogenic microorganisms and parasite eggs. The core of fermentation is the decomposition of complex organic matter into simpler substances through the metabolic action of microorganisms (bacteria, fungi, actinomycetes, etc.). The fermentation products (such as compost, biogas residue, and biogas slurry) are rich in nutrients such as nitrogen, phosphorus, and potassium, as well as organic matter. They can be used as organic fertilizer to replace some chemical fertilizers, improve soil structure (increase aeration and water retention), and enhance soil fertility.

[0003] However, current livestock and poultry manure fermentation equipment still suffers from uneven material decomposition, low processing efficiency, and insufficient stability, and needs further improvement and optimization. Summary of the Invention

[0004] The purpose of this invention is to provide a novel fully mixed anaerobic reactor that can better control the fermentation state in order to form waste with high nutrient value and obtain biogas fuel.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A novel fully mixed anaerobic reactor includes a main housing mechanism, within which an anaerobic stirring mechanism is installed. The main containment mechanism includes a vertically extending anaerobic reaction containment tank. Several initial feed pipes connected to the interior are fixed on the outer side of the anaerobic reaction containment tank near the upper end. Feed conveying pipes connected to the initial feed pipes are fixed on the initial feed pipes. The anaerobic reaction tank has a discharge pipe fixed to its interior near the bottom on the outside. A biogas collection tank is fixed on the top of the anaerobic reaction container. The biogas collection tank is connected to the inside of the anaerobic reaction container through a biogas collection connecting pipe. A biogas discharge pipe connected to the inside of the biogas collection tank is fixed on the outside of the biogas collection tank. The anaerobic stirring mechanism includes a stirring mechanism fixed support ring whose axis is fixed vertically in the anaerobic reaction container. A stirring mechanism rotating support ring is rotatably connected to the inner side of the stirring mechanism fixed support ring and is coaxial with it. A stirring mechanism support beam extending radially is fixed to the inner side of the stirring mechanism rotating support ring. A vertically extending main stirring shaft is rotatably connected to the stirring mechanism support beam. Multiple split stirring shafts are fixed on the main stirring shaft.

[0006] Preferably, the initial feed pipe is provided with a raw material extrusion and dewatering mechanism, which includes an extrusion and dewatering drive shaft rotatably connected to and coaxial with the initial feed pipe, and extrusion and dewatering blades extending spirally along its axis are fixed on the extrusion and dewatering drive shaft. The end of the initial feed pipe away from the anaerobic reaction container is fixed with a squeeze drive housing. One end of the squeeze dewatering drive shaft extends into the squeeze drive housing. The squeeze drive housing is fixed with a squeeze dewatering drive motor for driving the squeeze dewatering drive shaft to rotate. The output shaft of the squeeze dewatering drive motor is connected to the squeeze dewatering drive shaft through a coupling. The initial feed pipe has multiple internally and externally connected extrusion dewatering discharge holes on its side wall; An upward-facing leachate collection shell is fixed to the outside of the anaerobic reaction tank, below the initial feed pipe. A leachate discharge pipe connected to the inside of the leachate collection shell is fixed to the bottom of the tank.

[0007] Explanation: The initial feed pipe integrates a raw material extrusion and dehydration mechanism. By extruding the raw material through spiral blades, the moisture content of the material is reduced. This not only reduces the dilution of the anaerobic environment by excess water in the reactor, but also increases the organic matter concentration per unit volume of material, thereby improving gas production efficiency.

[0008] Preferably, the initial feed pipe is provided with a dehydration opening and closing mechanism, which includes a dehydration opening and closing control tube shell that is slidably connected to the outside of the initial feed pipe along the axial direction of the initial feed pipe. The side wall of the dehydration opening and closing control tube shell has a plurality of dehydration opening and closing mating holes that are radially through it. A dehydration opening and closing fixing cylinder extending parallel to its axis is fixed on the lower side of the initial feed pipe. A dehydration opening and closing sliding cylinder is slidably connected inside the dehydration opening and closing fixing cylinder. The outer end of the dehydration opening and closing sliding cylinder is fixedly connected to the dehydration opening and closing control pipe shell. The dehydration opening and closing fixed cylinder is equipped with a dehydration opening and closing drive rod for driving the movement of the dehydration opening and closing sliding cylinder.

[0009] Note: The dewatering opening and closing mechanism can control the opening and closing of the dewatering outlet through the sliding tube shell, flexibly adjusting the degree of dewatering and adapting to the characteristics of various raw materials.

[0010] Preferably, the anaerobic reaction container is provided with a circulation guiding mechanism, which includes multiple circulation guiding support shafts that extend radially along the anaerobic reaction container and are rotatably connected to the side wall of the anaerobic reaction container. A circulation guiding plate is fixed at one end of the circulation guiding support shaft inside the anaerobic reaction container. Multiple circulation guide drive shells are fixed to the outside of the anaerobic reaction tank. Multiple circulation guide support shafts extend one by one into each circulation guide drive shell. A circulation guide driven worm gear is fixed to one end of the circulation guide support shaft inside the circulation guide drive shell. A circulation guide drive motor is fixed inside the circulation guide drive shell. A circulation guide drive worm is fixed on the output shaft of the circulation guide drive motor. The circulation guide drive worm is meshed with the circulation guide driven worm gear.

[0011] Explanation: The circulating flow guiding mechanism guides the flow of livestock and poultry manure, which facilitates more thorough mixing of the manure. The interconnected circulating flow guiding plates form a spiral-extending flow guiding strip within the anaerobic reaction tank. The direction of rotation and the spiral angle of each circulating flow guiding plate are consistent during the arrangement process.

[0012] Preferably, a feeding and mixing mechanism is provided on the outside of the anaerobic reaction container. The feeding and mixing mechanism includes a mixing drive housing fixed on the outside of the anaerobic reaction container. A mixing delivery pump is fixed inside the mixing drive housing. The input end of the mixing delivery pump is connected to the inside of the anaerobic reaction container through a mixing delivery feed pipe. A mixing and conveying manifold is fixed to the feed conveying pipe and connected to it. The output end of the mixing and conveying pump is connected to the mixing and conveying manifold through the mixing pumping pipe.

[0013] Explanation: The feeding and mixing mechanism is used to mix the livestock and poultry manure in the anaerobic reaction tank with the initial livestock and poultry manure, so as to dilute the high concentration of the initial livestock and poultry manure and avoid impacting the microbial environment in the anaerobic reaction tank.

[0014] Preferably, the stirring mechanism support beam is provided with a main stirring drive housing, the main stirring shaft passes through and is rotatably connected to the main stirring drive housing in the vertical direction, the part of the main stirring shaft inside the main stirring drive housing is fixed with a main stirring driven gear, the main stirring drive motor is fixed inside the main stirring drive housing, the main stirring drive gear is fixed on the output shaft of the main stirring drive motor, and the main stirring drive gear is meshed with the main stirring driven gear. A radial stirring displacement support slide rail is fixed on the support beam of the stirring mechanism, and a radial stirring displacement support slider is slidably connected on the radial stirring displacement support slide rail. The main stirring drive housing is fixedly connected to the radial stirring displacement support slider.

[0015] Note: The main stirring shaft can move radially, and with the three-dimensional distribution of the split stirring shafts, it can cover a larger area inside the reactor. At the same time, the rotating support ring of the stirring mechanism drives the entire stirring assembly to rotate around the tank axis, realizing a compound motion of "revolution + rotation", which greatly improves the material mixing efficiency.

[0016] Preferably, the anaerobic reaction tank is equipped with a water injection mechanism. Both the main stirring shaft and the split stirring shaft are hollow structures, and the interior of the split stirring shaft is connected to the interior of the main stirring shaft. The water injection mechanism includes multiple water injection nozzles fixed on the outside of the split stirring shaft and connected to its interior. The top of the anaerobic reaction tank is fixed with a vertically extending main water supply pipe. The top of the main stirring shaft is connected to a water bridging supply pipe via a central rotary joint. The water bridging supply pipe is connected to the lower end of the main water supply pipe.

[0017] Instructions: When water needs to be added to livestock and poultry manure, a delivery pump is used to deliver water to the main water supply pipe. The water in the main water supply pipe will flow sequentially through the water supply bridging pipe and the central rotary joint into the main mixing shaft. The water inside the main mixing shaft will then enter each of the individual mixing shafts and finally be sprayed out from the water inlet nozzles to replenish the livestock and poultry manure.

[0018] Preferably, the bottom of the anaerobic reaction container is provided with a pneumatic stirring mechanism. The pneumatic stirring mechanism includes a pneumatic stirring integrated shell fixed to the bottom of the anaerobic reaction container. The top of the pneumatic stirring integrated shell has multiple vertically penetrating pneumatic stirring pipe connection holes. A pneumatic stirring conveying pipe is slidably connected in the pneumatic stirring pipe connection holes along the vertical direction. Multiple pneumatic stirring nozzles are fixed to the top of the pneumatic stirring conveying pipe and communicate with it. The biogas collection tank is connected to a pneumatic mixing and conveying pump via a pneumatic mixing output pipe. The pneumatic mixing output pipe is connected to the input end of the pneumatic mixing and conveying pump, and the output end of the pneumatic mixing and conveying pump is connected to each pneumatic mixing and conveying pipe via a pipeline.

[0019] Explanation: The biogas produced during the fermentation of livestock and poultry manure will be stored in a biogas collection tank through a biogas collection connection pipe. The biogas in the biogas collection tank will be used as a power source, combined with a pneumatic stirring mechanism to pneumatically stir the livestock and poultry manure in the anaerobic reaction tank.

[0020] Preferably, multiple vertically extending pneumatic array support plates are fixed inside the pneumatic stirring integrated shell, and vertically extending pneumatic array support slide rails are fixed on the sides of the pneumatic array support plates. Array lifting support sliders are slidably connected on the pneumatic array support slide rails, and array lifting support sliders are fixedly connected to the pneumatic stirring conveying pipe.

[0021] Explanation: The array lifting support slider is driven by a servo motor fixed on the pneumatic array support plate via a gear and rack to move along the pneumatic array support slide rail. The array lifting support slider then drives the pneumatic mixing and conveying pipe to move up and down, adjusting the position and height of each pneumatic mixing nozzle in the livestock and poultry manure. The pneumatic mixing nozzles on multiple pneumatic mixing and conveying pipes form a three-dimensional bubble generating array in the livestock and poultry manure, which helps to improve the uniformity of pneumatic mixing.

[0022] Compared with the prior art, the beneficial effects of the present invention are reflected in the following aspects: 1. The present invention has a reasonable structural design, with efficient mixing and reaction environment optimization. The multi-level mixing system improves the mixing uniformity. The anaerobic mixing mechanism adopts a composite structure of rotating support ring, radial support beam and multi-axis mixing. The main mixing shaft can move radially. With the three-dimensional distribution of split mixing shafts, it can cover a larger area in the reactor. At the same time, the rotating support ring of the mixing mechanism drives the overall mixing assembly to rotate around the tank axis, realizing the composite motion of "revolution + rotation", which greatly improves the material mixing efficiency and meets the core requirement of complete mixing. 2. This invention is easy to operate. Combined with a pneumatic stirring mechanism, it uses biogas generated by the reactor itself as a gas source. Bubbles are sprayed to the bottom through a liftable pneumatic stirring nozzle, which not only enhances the disturbance of the bottom material, but also realizes the recycling of biogas and reduces energy consumption. In addition, the height of the pneumatic stirring nozzle can be adjusted by a sliding rail slider to adapt to the stirring needs of various material concentrations and avoid local sedimentation or stratification. 3. The technical solution of the present invention has the function of raw material extrusion and dehydration. The initial feed pipe integrates the raw material extrusion and dehydration mechanism. The raw material is extruded by the spiral blades to reduce the moisture content of the material. This can reduce the dilution of the anaerobic environment by excess water in the reactor and increase the organic matter concentration per unit volume of material, thereby improving the gas production efficiency. 4. In the technical solution of the present invention, the feeding and mixing mechanism draws part of the fermentation liquid in the reactor back to the feeding conveying pipe, mixes it with the new raw materials, and then re-enters the reactor. This can not only adjust the pH and temperature of the feed, utilize the residual heat and buffering properties of the fermentation liquid, but also increase the probability of contact between the raw materials and microorganisms, thus accelerating the reaction start-up.

[0023] 5. In the technical solution of the present invention, the internal stirring design can also solve the problem that traditional mixing methods are prone to causing safety accidents. The anaerobic stirring mechanism adopts a structure design of multiple dispersed main stirring shafts + split stirring shafts. The main stirring shaft is only connected to the rotating support ring through the stirring mechanism support beam. There is no long shaft that penetrates the tank. The water injection and stirring shaft are sealed only at the top through the central rotating joint, rather than biogas sealing, which greatly reduces the sealing surface of biogas contact. When the traditional agitator shaft seal fails, external air can easily seep into the reactor through the seal gap. However, the agitator components of this invention have no direct communication path with the external air. The main agitator shaft is located inside the tank and clean water (not air) is introduced only through the main water supply pipe. The pneumatic agitator supply pipe is only connected to the biogas collection shell, completely isolating air and fundamentally eliminating the triggering conditions of "air infiltration - biogas explosion".

[0036] In practical application, the initial livestock and poultry manure to be treated first passes through a grid filter to remove large particles of impurities. After filtration, the livestock and poultry manure is then transported to the feed pipe 121 by a conveying pump of the prior art. The livestock and poultry manure in the feed pipe 121 then enters the anaerobic reaction containment tank 11 through the initial feed pipe 12. When livestock and poultry manure passes through the initial feed pipe 12, the raw material extrusion and dewatering mechanism 13 extrudes and dewaters the livestock and poultry manure. The output shaft of the extrusion and dewatering drive motor 134 drives the extrusion and dewatering drive shaft 131 to rotate. The extrusion and dewatering drive shaft 131 drives the extrusion and dewatering blades 132 to rotate together. The spirally extended extrusion and dewatering blades 132 extrude and dewater the livestock and poultry manure. In the dehydration opening and closing mechanism 14, when the dehydration opening and closing mating hole 140 is aligned and connected with the extrusion dehydration discharge hole 130, the dehydration opening and closing mechanism 14 is in the open state; when the dehydration opening and closing mating hole 140 is misaligned and isolated from the extrusion dehydration discharge hole 130, the dehydration opening and closing mechanism 14 is in the closed state. When the dehydration opening and closing mechanism 14 is in the open state, the water discharged from the livestock and poultry manure is discharged through the extrusion dehydration outlet hole 130 and the dehydration opening and closing matching hole 140 in sequence, and the water discharged from the poultry manure falls into the leachate collection shell 135 for unified collection. The extension or retraction of the inner rod of the dehydration opening and closing drive rod 144 can drive the dehydration opening and closing sliding cylinder 143 together with the dehydration opening and closing control tube shell 141 to move along the axial direction of the initial feed tube 12, thereby controlling whether each dehydration opening and closing mating hole 140 is connected to the extrusion dehydration discharge hole 130. During the fermentation process of livestock and poultry manure inside the anaerobic reaction container 11, the anaerobic stirring mechanism 20 is used to fully stir the livestock and poultry manure during the fermentation process. The output shaft of the main stirring drive motor 232 is connected to the main stirring driven gear 231 through the meshing of the main stirring drive gear 233, thereby driving the main stirring shaft 22 to rotate. The main stirring shaft 22 then drives multiple split stirring shafts 221 to rotate together, and the multiple split stirring shafts 221 are used to fully stir the livestock and poultry manure during the fermentation process. The radial stirring displacement support slider 241 is driven by a prior art servo motor fixed on the stirring mechanism support beam 212 via a gear and rack to move along the radial stirring displacement support slide rail 24. The radial stirring displacement support slider 241 then drives the main stirring drive housing 23, the main stirring shaft 22 and multiple split stirring shafts 221 to move together, so as to fully stir the livestock and poultry manure over a larger range. The biogas produced during the fermentation of livestock and poultry manure will enter the biogas collection tank 15 through the biogas collection connecting pipe 151 and be stored. The biogas in the biogas collection tank 15 will be used as a power source, and the pneumatic stirring mechanism 30 will be used to pneumatically stir the livestock and poultry manure in the anaerobic reaction container tank 11. The biogas in the biogas collection tank 15 is transported to each pneumatic stirring and conveying pipe 32 by the pneumatic stirring and conveying pump 323. The biogas in the pneumatic stirring and conveying pipe 32 is then sprayed out from multiple pneumatic stirring nozzles 321, causing the biogas to form bubbles in the livestock and poultry manure. These bubbles move from bottom to top in the livestock and poultry manure, thereby stirring the livestock and poultry manure. The bubbles that overflow from the surface of the livestock and poultry manure will return to the biogas collection tank 15 for storage through the biogas collection connecting pipe 151. The array lifting support slider 332 is driven by a conventional servo motor fixed on the pneumatic array support plate 33 through a gear and rack to move along the pneumatic array support slide rail 331. The array lifting support slider 332 then drives the pneumatic stirring and conveying pipe 32 to move up and down, adjusting the position and height of each pneumatic stirring nozzle 321 in the livestock and poultry manure. The pneumatic stirring nozzles 321 on the multiple pneumatic stirring and conveying pipes 32 form a three-dimensional bubble generating array in the livestock and poultry manure, which is beneficial to improving the uniformity of pneumatic stirring. During the mixing process of livestock and poultry manure, the circulating guide mechanism 16 plays a guiding role in the livestock and poultry manure, which is conducive to more thorough mixing of the livestock and poultry manure. The circulating guide plates 160 are connected end to end and can form a spiral extending guide strip in the anaerobic reaction tank 11. The direction of rotation and the spiral angle of each circulating guide plate 160 are consistent during the arrangement process. The output shaft of the circulating guide drive motor 164 is connected to the circulating guide driven worm 165 and the circulating guide driven worm wheel 163 through the meshing of the circulating guide drive worm 165. This can drive the circulating guide support shaft 161 to rotate, and the circulating guide support shaft 161 in turn drives the circulating guide plate 160 to deflect along with it, thereby adjusting the tilt angle of the circulating guide plate 160. During the fermentation process of livestock and poultry manure, when water needs to be added to the manure, the existing technology of the conveying pump is used to deliver water to the main water delivery pipe 42. The water in the main water delivery pipe 42 will flow through the water bridging delivery pipe 43 and the central rotary joint 431 into the main stirring shaft 22. The water inside the main stirring shaft 22 will then enter each of the separate stirring shafts 221 and finally be sprayed out from the water inlet nozzle 41 to replenish the livestock and poultry manure. During the fermentation process of livestock and poultry manure, the feeding and mixing mechanism 17 is used to mix the livestock and poultry manure in the anaerobic reaction container 11 with the initial feeding livestock and poultry manure to dilute the high concentration of the initial livestock and poultry manure and avoid impacting the microbial environment in the anaerobic reaction container 11. The livestock and poultry manure in the anaerobic reaction containment tank 11 enters the input end of the mixing and conveying pump 172 through the mixing and conveying feed pipe 173, and is pumped by the mixing and conveying pump 172 through the mixing pumping pipe 175 to the mixing and conveying manifold 174. The livestock and poultry manure in the mixing and conveying manifold 174 then enters the feed conveying pipe 121 and mixes with the initial livestock and poultry manure after filtration, and then enters the anaerobic reaction containment tank 11 again through the initial feed pipe 12.
