Description

Technical Field

[0001] This utility model belongs to the field of anaerobic ammonia treatment technology, and in particular relates to an anaerobic ammonia oxidation reactor. Background Technology

[0002] With the rapid development of science and technology and the continuous improvement of industrialization and urbanization, the problem of eutrophication of water bodies has become increasingly serious, making water resources even more scarce. Nitrogen is the main factor causing eutrophication, so more and more countries and regions have formulated nitrogen emission standards. Therefore, the research and development of economical and efficient denitrification technologies has become a research focus in the field of water pollution control engineering. Compared with physicochemical treatment methods, biological treatment has advantages such as lower treatment costs and no secondary pollution to the environment. Therefore, biological treatment has become the main means of secondary and tertiary wastewater treatment. Nitrogen can be transformed into various oxidation states and chemical forms under the action of corresponding microorganisms. Therefore, a large number of combined processes have been derived in biological denitrification treatment of wastewater, and anaerobic ammonia oxidation is currently the most efficient biological denitrification process.

[0003] For example, Chinese patent CN221988321U discloses an anaerobic ammonia oxidation reactor, belonging to the field of reactor technology. Addressing the problem of the inability to quickly and thoroughly mix materials, the invention includes a reactor body. A top plate is fixedly connected to the top of the reactor body, and an mounting plate is fixedly connected to the reactor body below the top plate. A motor is fixedly connected to the top of the top plate, and an mounting frame is fixedly installed outside the motor and connected to the reactor body. A fixed shaft is fixedly connected to the output end of the motor and passes through the mounting plate and is located inside the reactor body via a bearing. A mixing mechanism is provided between the mounting plate and the top plate on the fixed shaft, and a stirring mechanism is provided outside the fixed shaft inside the reactor body. This invention, through its stirring mechanism, can quickly stir the materials inside the reactor body, and the mixing efficiency during the stirring process is high, facilitating a thorough reaction within the reactor body.

[0004] This patented device has several drawbacks in its use. While it effectively agitates the wastewater, it cannot guarantee that the wastewater within the reactor cavity is suitable for the active growth of anaerobic bacteria. It also lacks the ability to quickly and easily adjust and monitor temperature, pH, and oxygen levels within the reactor. This makes the anaerobic bacteria highly susceptible to inactivation due to unsuitable environmental conditions, leading to a decrease in the anaerobic ammonia oxidation reaction rate. Furthermore, the device uses a mounting base and sealed bearings to mount and rotate the central agitator. Since the agitator is submerged for extended periods, its connection points are prone to damage and leakage after prolonged operation, causing irreversible damage to the transmission gears and resulting in a short overall lifespan. Therefore, we propose an anaerobic ammonia oxidation reactor. Utility Model Content

Detailed Implementation

[0018] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0019] In this application, the terms "upper," "lower," "left," "right," "front," "rear," "top," "bottom," "inner," "outer," "middle," "vertical," and "horizontal," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0020] Example 1: This example provides an anaerobic ammonia oxidation reactor, comprising: The reaction vessel 1 has a top-opening, hollow internal structure. The upper surface of the reaction vessel 1 is provided with a top cover 2. The side walls of the reaction vessel 1 are symmetrically provided with heat dissipation holes 3. The upper surface of the reaction vessel 1 is symmetrically provided with mounting grooves 4. An electric hydraulic cylinder 15 is fixedly installed in the mounting groove 4, and the top end of the telescopic rod of the electric hydraulic cylinder 15 is fixed to the lower surface of the top cover 2. The inner cavity of the reaction vessel 1 is fixedly installed with an inner reaction cylinder 5 arranged coaxially, and the upper surface of the inner reaction cylinder 5 is flush with the upper surface of the reaction vessel 1. A stirring mechanism is installed on the upper cover 2 and is used to stir the raw materials inside the inner reaction cylinder 5. A temperature control mechanism is installed on the inner reaction cylinder 5 and is used to regulate the temperature inside the inner reaction cylinder 5. Gas supply pipe 23 and exhaust pipe 24 are both fixedly installed on the upper surface of the upper cover 2 and are connected to the inner cavity of the inner reaction cylinder 5.

[0021] The process involves activating the electric hydraulic cylinder 15, causing its extension rod to rise and lift the upper cover 2 and the stirring mechanism. Then, the wastewater containing ammonia nitrogen is introduced into the inner cavity of the inner reaction cylinder 5. The temperature and pH of the mixed solution within the inner reaction cylinder 5 are measured in real time using pH sensor 21 and temperature sensor 22. The pH of the wastewater is controlled by adding acid or alkali to maintain it between 6 and 8. After adjusting the pH, the temperature is controlled by the temperature control mechanism. After adjustment, anaerobic bacteria are added, and the upper cover 2 is closed. Aeration is then pumped from the inner reaction cylinder 5 to ensure a suitable anaerobic environment. The process continues until dissolved oxygen is released from the wastewater within the inner reaction cylinder 5. After the temperature adjustment is completed, the stirring mechanism is started to stir the wastewater appropriately, thereby accelerating the mixing and reaction of the anaerobic bacteria agent with the wastewater. When venting oxygen, nitrogen can be introduced into the inner cavity of the inner reaction cylinder 5 through the gas supply pipe 23, and the oxygen outlet is connected to the exhaust pipe 24, so that the oxygen content in the inner cavity of the inner reaction cylinder 5 decreases. Specifically, the bottom end of the gas supply pipe 23 is set in the lower part of the inner cavity of the inner reaction cylinder 5. When the wastewater enters the inner reaction cylinder 5, nitrogen is introduced through the gas supply pipe 23. The nitrogen rises and gradually fills the inner cavity of the inner reaction cylinder 5, squeezing the oxygen into the upper space, and finally discharged through the exhaust pipe 24. It is worth mentioning that an oxygen concentration sensor can be installed on the upper surface of the cover 2 to detect the oxygen content in the inner cavity of the inner reaction cylinder 5.

[0022] Example 2: This example provides an anaerobic ammonia oxidation reactor, which, in addition to the technical solutions of the above examples, also has the following technical features: the stirring mechanism consists of a tumbling component and an external stirring component, the tumbling component including: Motor 6 is fixedly installed at the center of the upper surface of the upper cover 2. The main stirring rod 12 is rotatably installed at the center of the lower surface of the upper cover 2. Spiral blades 13 are fixedly installed on the outer circumference of the main stirring rod 12. The output shaft of motor 6 passes through the upper cover 2 and is coaxially connected to the main stirring rod 12.

[0023] The motor 6 is started, and the output shaft of the motor 6 rotates, which drives the main stirring rod 12 to rotate. When the main stirring rod 12 rotates, it can drive the spiral blade 13 to rotate synchronously. The spiral blade 13 can drive the wastewater in the middle of the inner cavity of the inner reaction cylinder 5 to surge upward, thereby accelerating the rapid fusion and reaction between the wastewater in the middle of the inner cavity of the inner reaction cylinder 5 and the anaerobic bacteria.

[0024] By setting up a turbulence component, the anaerobic ammonia oxidation treatment of wastewater in the middle of the inner cavity of the inner reaction cylinder 5 was accelerated.

[0025] Example 3: This example provides an anaerobic ammonia oxidation reactor, which, in addition to the technical solutions of the above examples, also has the following technical features: the external stirring assembly includes: The driving wheel 7 is coaxially mounted on the upper part of the main stirring rod 12. A gear ring 8 is fixedly mounted on the lower surface of the upper cover 2, and the gear ring 8 is coaxially arranged with the upper cover 2. Multiple driven wheels 9 are meshed between the driving wheel 7 and the gear ring 8. A secondary stirring rod 14 is coaxially fixed on the lower surface of the driven wheel 9. Multiple stirring blades are fixedly mounted on the secondary stirring rod 14.

[0026] When the output shaft of the motor 6 drives the main stirring rod 12 to rotate, the driving wheel 7 will also rotate synchronously with the main stirring rod 12. The driving wheel 7 drives the driven wheel 9 to rotate, and under the action of the gear ring 8, multiple driven wheels 9 can rotate around the driving wheel 7 as the axis in the inner ring of the gear ring 8. That is, when the driven wheel 9 rotates, it can drive the auxiliary stirring rod 14 to rotate. The auxiliary stirring rod 14 drives multiple stirring blades on its surface wall to rotate, thereby stirring the wastewater on the outer side of the inner reaction cylinder 5, thereby accelerating the reaction between the wastewater and anaerobic bacteria on the outer side. At the same time, the auxiliary stirring rod 14 also rotates on the outer side of the inner reaction cylinder 5, so that the wastewater at various positions on the outer side of the inner reaction cylinder 5 can be stirred.

[0027] By setting an external stirring component, the contact efficiency between wastewater and anaerobic bacteria at the outer position of the inner reaction cylinder 5 is improved, thereby accelerating the reaction rate of anaerobic ammonia oxidation of wastewater by anaerobic bacteria.

[0028] Example 4: This example provides an anaerobic ammonia oxidation reactor. In addition to the technical solutions of the above examples, it also has the following technical features: the lower surface of the upper cover 2 is provided with an annular groove 10 with a T-shaped cross-section. Multiple connecting blocks 11, the same number as the driven wheels 9, are movably installed in the annular groove 10. The connecting blocks 11 are coaxially connected to the driven wheels 9 at the corresponding positions.

[0029] When the driven wheel 9 rotates and moves under the action of the gear ring 8, it can make circular motion under the action of the connecting block 11 and the annular groove 10.

[0030] Example 5: This example provides an anaerobic ammonia oxidation reactor, which, in addition to the technical solutions of the above examples, also has the following technical features: the temperature control mechanism consists of a heating component and a heat dissipation component, and the heating component includes: Multiple electric heating tubes 18 are evenly and fixedly installed on the outer circumference of the inner reaction cylinder 5. A protective cover 19 is provided on the outside of the electric heating tubes 18, and the protective cover 19 is fixed to the outer wall of the inner reaction cylinder 5.

[0031] When the heating component is working, multiple electric heating tubes 18 are activated. After the electric heating tubes 18 are powered on, they generate heat and heat the inner reaction cylinder 5, thereby increasing the temperature of the wastewater inside the inner reaction cylinder 5.

[0032] By setting up a heating component, the temperature rise of the wastewater inside the inner reaction cylinder 5 can be controlled.

[0033] Example 6: This example provides an anaerobic ammonia oxidation reactor, which, in addition to the technical solutions of the above examples, also has the following technical features: the heat dissipation component includes: Multiple sets of heat-conducting fins 17 are evenly distributed and fixedly installed on the outer circumference of the inner reaction cylinder 5. The heat-conducting fins 17 are arranged between adjacent protective covers 19. A fan 16 is fixedly installed in the heat dissipation hole 3. A temperature acquisition device 20 is fixedly installed on the outer circumference of the reaction tank 1, and the probe of the temperature acquisition device 20 is arranged in the interlayer between the inner reaction cylinder 5 and the reaction tank 1.

[0034] When the heat dissipation component is working, the heating component stops operating. By starting the fan 16, the fan 16 generates negative pressure. One fan 16 blows air inward, and the other fan 16 blows air outward, thus forming a complete air duct. This rapidly cools the high-temperature air between the inner reaction cylinder 5 and the reaction tank 1. The temperature on the inner reaction cylinder 5 is also dissipated into the interlayer through multiple heat-conducting fins 17. As the temperature decreases, the temperature of the wastewater in the inner reaction cylinder 5 also decreases. Through the detection of the temperature acquisition device 20 and the temperature sensor 22, the temperature of the wastewater in the inner cavity of the inner reaction cylinder 5 is controlled to ensure that the temperature of the wastewater is at a suitable temperature for the anaerobic bacteria to be active, thereby improving the overall reaction rate of the anaerobic ammonia oxidation reaction of the device.

[0035] Example 7: This example provides an anaerobic ammonia oxidation reactor. In addition to the technical solutions of the above examples, it also has the following technical features: a pH sensor 21 and a temperature sensor 22 are fixedly installed on the upper surface of the cover 2, and the probes of the pH sensor 21 and the temperature sensor 22 are set in the inner cavity of the inner reaction cylinder 5.

[0036] Example 8: This example provides an anaerobic ammonia oxidation reactor, which, in addition to the technical solutions of the above examples, also has the following technical features: a discharge pipe is fixedly installed on the lower surface of the reaction vessel 1, and a discharge valve is fixedly installed on the discharge pipe.

[0037] After the initial anaerobic ammonia oxidation reaction of the wastewater is completed, the discharge valve is opened, allowing the wastewater to be discharged to the next process through the discharge pipe.

[0038] By setting up a discharge pipe, it is convenient to discharge wastewater from the inner cavity of the inner reaction cylinder 5.

[0039] Working principle: The electric hydraulic cylinder 15 is activated. The telescopic rod of the electric hydraulic cylinder 15 is lifted upward, which drives the upper cover 2 and the stirring mechanism to rise. Then, the wastewater containing ammonia nitrogen to be treated is put into the inner cavity of the inner reaction cylinder 5. After the pH value, temperature and oxygen content of the wastewater in the inner cavity of the inner reaction cylinder 5 are regulated, the wastewater is stirred to accelerate the reaction between anaerobic bacteria and wastewater. During stirring, motor 6 is started, and the output shaft of motor 6 rotates, driving the main stirring rod 12 to rotate. The rotation of the main stirring rod 12 drives the spiral blades 13 to rotate synchronously. The spiral blades 13 cause the wastewater in the middle of the inner reaction cylinder 5 to surge upwards, thereby accelerating the rapid fusion and reaction between the wastewater and anaerobic bacteria in the middle of the inner reaction cylinder 5. When the output shaft of motor 6 drives the main stirring rod 12 to rotate, the driving wheel 7 also rotates synchronously with the main stirring rod 12. The driving wheel 7 drives the driven wheel 9 to rotate, and... Under the action of the gear ring 8, multiple driven wheels 9 can rotate around the driving wheel 7 on the inner ring of the gear ring 8. That is, when the driven wheels 9 rotate, they can drive the auxiliary stirring rod 14 to rotate. The auxiliary stirring rod 14 drives multiple stirring blades on its surface to rotate, thereby stirring the wastewater on the outer side of the inner cavity of the inner reaction cylinder 5, thereby accelerating the reaction between the wastewater on the outer side and the anaerobic bacteria. At the same time, the auxiliary stirring rod 14 also rotates on the outer side of the inner reaction cylinder 5, so that the wastewater at all positions on the outer side of the inner reaction cylinder 5 can be stirred. After the reaction is complete, the wastewater can be discharged through the discharge pipe.
