Description

Technical Field

[0001] This invention relates to the field of manure treatment technology, and in particular to a high-temperature, high-pressure steam-type chicken manure pyrolysis treatment device. Background Technology

[0002] With the rapid development of large-scale chicken farming, the amount of chicken manure discharged has exploded. Statistics show that the daily manure production per 10,000 laying hens can reach 1.5-2.0 tons, and large-scale broiler farms often discharge over 1,000 tons of manure annually. Chicken manure not only contains a large amount of organic matter, nitrogen, phosphorus, potassium, and other nutrients, but also undigested feed residues, pathogenic microorganisms, parasite eggs, and antibiotic residues. Improper handling can lead to a series of environmental problems: when stored in the open, the fermentation of manure produces ammonia, hydrogen sulfide, and other foul-smelling gases that pollute the atmosphere; leachate from rainwater runoff seeps into the soil and groundwater, causing soil salinization and eutrophication of water bodies, threatening the balance of the ecosystem; and the spread of pathogenic microorganisms can lead to cross-infection of livestock and poultry diseases, causing economic losses to the livestock industry.

[0003] Currently, chicken manure treatment technologies mainly include composting, anaerobic digestion, drying, and incineration. While composting can convert chicken manure into organic fertilizer, it suffers from long processing times (typically 20-30 days), large land requirements, and the potential for foul odor pollution during fermentation. Furthermore, the finished product has uneven fertilizer efficiency, and some pathogenic microorganisms are difficult to completely inactivate. Anaerobic digestion allows for biogas recovery, but it requires high-level pretreatment of chicken manure, necessitating control of the solid-liquid ratio and carbon-nitrogen ratio. It also involves significant equipment investment and complex operation and maintenance, making it unsuitable for small and medium-sized farms. Drying reduces the moisture content of chicken manure, facilitating storage and transportation, but it consumes a lot of energy and only achieves physical dehydration, failing to decompose organic matter and remove harmful substances, leaving environmental risks associated with subsequent disposal. Incineration can rapidly reduce volume and render the manure harmless, but it produces toxic and harmful gases such as dioxins and nitrogen oxides during combustion. This places extremely high environmental requirements on incineration equipment, resulting in high investment and operating costs, making it difficult to widely promote in the livestock industry. High-temperature, high-pressure steam pyrolysis technology, with its advantages of rapidly decomposing organic matter and completely inactivating pathogenic microorganisms, has become an ideal choice for chicken manure treatment. This technology uses high-temperature, high-pressure steam to rapidly decompose the organic matter in chicken manure into smaller molecules, while simultaneously killing harmful organisms such as bacteria, viruses, and parasite eggs, achieving harmless treatment. The pyrolysis products can be further processed into organic fertilizer, biochar, or biomass energy, realizing resource recycling. Existing pyrolysis equipment separates stirring and high-temperature steam supply. Although this allows for sufficient contact between the chicken manure and the high-temperature steam, it requires prolonged mixing, resulting in long processing cycles and high energy consumption. Furthermore, the single-tank structure suffers from the drawback of not being able to synchronize feeding, discharging, and the pyrolysis process, leading to poor equipment continuity and difficulty in improving processing efficiency. Therefore, there is an urgent need for a pyrolysis device that solves these problems. Summary of the Invention

[0027] Reference Figure 1 , Figure 2The system includes a first pyrolysis tank 1 and a second pyrolysis tank 2 with identical structures. Several support legs 3 are welded to or detachably fixed to the bottom of the outer wall of either the first pyrolysis tank 1 or the second pyrolysis tank 2, with at least three support legs 3 evenly connected to the bottom of the outer wall. These support legs 3 are connected to a fixing ring, thus providing stable support for the first pyrolysis tank 1 or the second pyrolysis tank 2. The top of the first pyrolysis tank 1 or the second pyrolysis tank 2 is connected to an inlet pipe 4 and an exhaust pipe 35. Chicken manure is fed into the first pyrolysis tank 1 or the second pyrolysis tank 2 through the inlet pipe 4. During operation, a feed hopper and a screw conveyor are typically used to feed the chicken manure raw material into the inlet pipe 4, and the exhaust pipe 35 discharges the waste gas from the first pyrolysis tank 1 or the second pyrolysis tank 2 for subsequent harmless treatment.

[0028] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 A steam input unit is connected to either the first pyrolysis tank 1 or the second pyrolysis tank 2, allowing high-temperature steam to be supplied to the tank, facilitating the high-temperature, high-pressure steam pyrolysis of chicken manure within. The steam input unit is connected to a rotating shaft 10 that extends partially into the tank, allowing high-temperature steam to enter the shaft 10 and then flow into the corresponding tank. The steam input unit includes a steam input seat 8, a steam input pipe 44, and a support seat 9. The steam input seat 8 and the support seat 9 are detachably and fixedly connected to the first pyrolysis tank 1 or the second pyrolysis tank 2 by bolts, and are located axially in the horizontal direction of the tank, thus connecting the steam input seat 8 to the tank. A first mounting groove 17 and a second mounting groove 22 are respectively provided on the steam input seat 8 and the support seat 9. A first support bearing 18 and a second support bearing 23 are respectively interference-fitted into the first mounting groove 17 and the second mounting groove 22, so that the first support bearing 18 and the second support bearing 23 are respectively connected to the steam input seat 8 and the support seat 9. The two ends of the rotating shaft 10 are respectively interference-fitted into the first support bearing 18 and the second support bearing 23, so that the two ends of the rotating shaft 10 are respectively connected to the steam input seat 8 and the support seat 9 through the first support bearing 18 and the second support bearing 23, and the rotating shaft 10 can rotate relative to the steam input seat 8 and the support seat 9 through the first support bearing 18 and the second support bearing 23, thereby enabling it to rotate relative to the first pyrolysis tank 1 or the second pyrolysis tank 2.

[0029] Reference Figure 2 , Figure 3 , Figure 4 The first mounting groove 17 and the second mounting groove 22 are respectively provided with a first connecting groove 11 and a second connecting groove 12 that connect the inside of the first pyrolysis tank 1 or the second pyrolysis tank 2. The rotating shaft 10 is disposed in the first connecting groove 11 and the second connecting groove 12, so that the rotating shaft 10 can pass through the first pyrolysis tank 1 or the second pyrolysis tank 2. The inner wall of the first connecting groove 11 is provided with a plurality of first snap-fit ​​ring grooves 14, and the outer end face of one end of the rotating shaft 10 is provided with a plurality of second snap-fit ​​ring grooves 15. A first sealing ring 16 is snapped into the second snap-fit ​​ring grooves 15 and the first snap-fit ​​ring grooves 14, so that the first sealing ring 16 is snapped and limited by the first snap-fit ​​ring grooves 14 and the second snap-fit ​​ring grooves 15, preventing the first sealing ring 16 from detaching from the first connecting groove 11 and the rotating shaft 10. At the same time, the first sealing ring 16 is used to seal the gap between the rotating shaft 10 and the first connecting groove 11, preventing high-temperature steam from leaking out from the gap between the rotating shaft 10 and the first connecting groove 11, thereby sealing one end of the rotating shaft 10 and the steam input seat 8, ensuring the sealing inside the first pyrolysis tank 1 or the second pyrolysis tank 2, thereby forming a high-pressure environment. The inner wall of the second connecting groove 12 is provided with several third snap-fit ​​ring grooves 19, and the outer end face of one end of the rotating shaft 10 is provided with several fourth snap-fit ​​ring grooves 20. The third snap-fit ​​ring grooves 19 and the fourth snap-fit ​​ring grooves 20 are engaged with the second sealing ring 21, so that the second sealing ring 21 is engaged and limited by the third snap-fit ​​ring grooves 19 and the fourth snap-fit ​​ring grooves 20, preventing the second sealing ring 21 from detaching from the second connecting groove 12 and the rotating shaft 10. At the same time, the second sealing ring 21 is used to seal the gap between the rotating shaft 10 and the second connecting groove 12, preventing high-temperature steam from leaking out from the gap between the rotating shaft 10 and the second connecting groove 12, thereby sealing one end of the rotating shaft 10 and the support seat 9, ensuring the sealing inside the first pyrolysis tank 1 or the second pyrolysis tank 2, thereby forming a high-pressure environment.

[0030] Reference Figure 2 , Figure 3 , Figure 4 An external air inlet is provided on the steam input seat 8 between the first locking ring grooves 14. The external air inlet is connected to the steam input pipe 44, which is connected to the steam boiler. This allows the high-temperature and high-pressure steam generated by the steam boiler to be transported to the steam input seat 8 through the steam input pipe 44 and the external air inlet. An air inlet groove 24 corresponding to the external air inlet is provided on the rotating shaft 10 between the second locking ring grooves 15. An internal air inlet 25 communicating with the interior of the rotating shaft 10 is provided in the air inlet groove 24. This allows the high-temperature and high-pressure steam to enter the external air inlet through the steam input pipe 44, then enter the air inlet groove 24 through the external air inlet, and finally enter the rotating shaft 10 through the internal air inlet 25.

[0031] Reference Figure 1 , Figure 2 , Figure 6A mixing and stirring unit is connected to the rotating shaft 10, which thoroughly mixes and stirs the chicken manure raw materials in the first pyrolysis tank 1 or the second pyrolysis tank 2, thereby ensuring sufficient contact between the high-temperature steam and the chicken manure and improving the pyrolysis efficiency of the chicken manure. The mixing and stirring unit includes a mixing and stirring motor 29, a mixing and stirring rod 26, and a tank wall scraping assembly. The mixing and stirring motor 29 is detachably fixed to the first pyrolysis tank 1 or the second pyrolysis tank 2 by bolts, so that the mixing and stirring motor 29 is connected to the first pyrolysis tank 1 or the second pyrolysis tank 2. The output shaft of the mixing and stirring motor 29 is connected to the rotating shaft 10, so that the mixing and stirring motor 29 is energized and its output shaft drives the rotating shaft 10 to rotate. Specifically, the end of the rotating shaft 10 has a non-circular insertion groove, and the end of the output shaft of the mixing and stirring motor 29 is non-circular, with one end of the output shaft of the mixing and stirring motor 29 inserted into the insertion groove. A gas inlet is provided inside the rotating shaft 10. The mixing rod 26 is U-shaped and connected to the rotating shaft 10, communicating with the gas inlet. A gas outlet is provided on the lower end face of the mixing rod 26, allowing high-temperature steam to enter the gas inlet and then into the mixing rod 26. Simultaneously, the mixing rod 26 and the rotating shaft 10 rotate together, causing the rotating shaft 10 to rotate and thus driving the mixing rod 26 to rotate, thereby achieving thorough mixing of the chicken manure. At the same time, the high-temperature steam is discharged through the mixing rod 26, fully mixing with the chicken manure. Several mixing rods 26 are uniformly and sealedly welded to the rotating shaft 10 in a ring shape, with adjacent mixing rods 26 staggered vertically. This allows for rapid, uniform, and thorough mixing of the chicken manure through the staggered arrangement of the mixing rods 26. The tank wall scraping assembly is connected to the end of the mixing and stirring rod 26 away from the rotating shaft 10. When the high-temperature steam is discharged, it drives the tank wall scraping assembly to rotate, thereby contacting the inner wall of the first pyrolysis tank 1 or the second pyrolysis tank 2. As the rotating shaft 10 drives the mixing and stirring rod 26 to rotate, the inner wall of the first pyrolysis tank 1 or the second pyrolysis tank 2 is scraped off, preventing chicken manure from adhering to the inner wall of the first pyrolysis tank 1 or the second pyrolysis tank 2.

[0032] Reference Figure 1 , Figure 2 , Figure 6 The tank wall scraping assembly includes a scraper 28 and a connecting block 27. The connecting block 27 is detachably fixed to the mixing rod 26 by bolts, thus connecting the connecting block 27 and the mixing rod 26 together. The scraper 28 is detachably fixed to the connecting block 27 by bolts, thus connecting the connecting block 27 and the scraper 28 together, and further connecting it to the mixing rod 26, enabling simultaneous rotation. The curvature of the scraper 28 is the same as the curvature of the inner wall of the first pyrolysis tank 1 or the second pyrolysis tank 2, so that the scraper 28 conforms to the inner wall of the first pyrolysis tank 1 or the second pyrolysis tank 2, thereby enabling the scraping and cleaning of the inner wall of the first pyrolysis tank 1 or the second pyrolysis tank 2.

[0033] Reference Figure 1 , Figure 2 , Figure 5 The exhaust pipe 35 is connected to a pressure relief regulating unit, which adjusts the maximum pressure of the first pyrolysis tank 1 or the second pyrolysis tank 2. This allows the first pyrolysis tank 1 or the second pyrolysis tank 2 to exhaust gas through the exhaust pipe 35 and the pressure relief regulating unit when pyrolysis is not required, and to create a high-pressure environment within the first pyrolysis tank 1 or the second pyrolysis tank 2 when needed. The pressure relief regulating unit includes a regulating connector 36, a pressure relief ball 40, a pressure relief spring 39, and an exhaust pipe 37. The outer surface of the exhaust pipe 35 has an external thread 42, and one end of the regulating connector 36 has an internal thread 43. The exhaust pipe 35 and the regulating connector 36 are detachably connected via the external thread 42 and the internal thread 43. The distance between the regulating connector 36 and the sealing cover can be adjusted by rotating the regulating connector 36, thereby regulating the pressure environment within the first pyrolysis tank 1 or the second pyrolysis tank 2. A limiting ring plate 38 is welded to the regulating connector 36, connecting the limiting ring plate 38 to the regulating connector 36. A pressure relief ball 40 is disposed within the regulating connector 36 and positioned between the limiting ring plate 38 and the exhaust pipe 35, thereby sealing the opening of the exhaust pipe 35. The two ends of the pressure relief spring 39 abut against the limiting ring plate 38 and the pressure relief ball 40 respectively, providing elastic force to the pressure relief ball 40, allowing it to seal the exhaust pipe 35 without external force. The outer surface of the pressure relief ball 40 is covered with a rubber sealing layer 41, enabling a more tight seal of the exhaust pipe 35. During use, the distance between the limiting ring plate 38 and the exhaust pipe 35 is adjusted by rotating the regulating connector 36, thereby compressing the pressure relief spring 39 and providing a greater pressure environment within the first pyrolysis tank 1 or the second pyrolysis tank 2. The outer surface of the regulating connector 36 is polygonal, facilitating its rotation.

[0034] Reference Figure 1 , Figure 2 , Figure 5The bottom of either the first pyrolysis tank 1 or the second pyrolysis tank 2 is connected to a discharge pipe 30, facilitating the discharge of pyrolyzed chicken manure from the first pyrolysis tank 1 or the second pyrolysis tank 2. The discharge pipes 30 at the bottom of the first pyrolysis tank 1 and the second pyrolysis tank 2 are connected, specifically a T-junction. This T-junction connects to an outlet pipe 31 and a migration pipe 32. The migration pipes 32 on both the first pyrolysis tank 1 and the second pyrolysis tank 2 are connected, allowing the chicken manure to flow within both tanks and achieve thorough mixing. A second valve 33 and a third valve 34 are connected to the outlet pipe 31 and the migration pipe 32, respectively, allowing control of their opening and closing. A first valve 5 is connected to the inlet pipe 4, allowing control of its opening and closing. The first valve 5, the second valve 33, and the third valve 34 can also be solenoid valves. The solenoid valves are electrically connected to a microcontroller control module assembly, thereby controlling the opening and closing of the three solenoid valves according to the microcontroller control module assembly.

[0035] In operation, firstly, open the first valve 5 on the first pyrolysis tank 1, and close the second valve 33 and the third valve 34 on the first pyrolysis tank 1. Simultaneously, loosen the regulating joint 36 to create a lower pressure environment inside the first pyrolysis tank 1. Next, chicken manure raw material is fed into the first pyrolysis tank 1 through the feed pipe 4 via the screw conveyor. During the conveying process, the mixing and stirring motor 29 is energized, and high-temperature saturated steam is input through the steam input pipe 44. The steam pressure is set to ≥1.6 MPa. The high-temperature steam enters the rotating shaft 10 and is discharged into the first pyrolysis tank 1 through the mixing and stirring rod 26. Simultaneously, the mixing and stirring motor 29 drives the rotating shaft 10 to rotate, which in turn drives the mixing and stirring rod 26 to rotate, thereby achieving rapid and thorough mixing of the chicken manure in the first pyrolysis tank 1. This ensures that the chicken manure is evenly contacted with the high-temperature steam until a certain amount of chicken manure has been conveyed. Then, close the screw conveyor and the first valve 5. After the mixing and stirring rod 26 has been mixing the chicken manure in the first pyrolysis tank 1 for a period of time, open the third valve 34. Simultaneously, tighten the regulating connector 36 on the first pyrolysis tank 1. At this time, the first valve 5 and the second valve 33 of the second pyrolysis tank 2 are closed, and the regulating connector 36 on the second pyrolysis tank 2 is in a loose state. Under the pressure of high-temperature steam, the chicken manure in the first pyrolysis tank 1 is pushed into the second pyrolysis tank 2 through the migration pipe 32, so that the chicken manure can be mixed more evenly. During this process, the mixing and stirring motor 29 on the second pyrolysis tank 2 is turned on, and high-temperature steam is supplied through the steam input pipe 44 on the second pyrolysis tank 2. When all the chicken manure in the first pyrolysis tank 1 has entered the second pyrolysis tank 2, the third valve 34 is closed, and the mixing and stirring motor 29 and the high-temperature steam input on the first pyrolysis tank 1 are turned off. Then tighten the regulating connector 36 on the second pyrolysis tank 2, and continue to supply high-temperature steam into the second pyrolysis tank 2 until the second pyrolysis tank 2 maintains a high temperature and high pressure state. Stop supplying high-temperature steam into the second pyrolysis tank 2, so that the second pyrolysis tank 2 is maintained for a certain period of time. Finally, after the pyrolysis is completed, open the second valve 33 to discharge the chicken manure in the second pyrolysis tank 2, thus completing the high-temperature and high-pressure pyrolysis of chicken manure.

For any fixed connections mentioned above, welding is preferred.
