Description

Technical Field

[0001] The utility model belongs to the technical field of sewage treatment equipment, in particular to an IC anaerobic tower. Background Art

[0002] IC anaerobic tower is an internal circulation anaerobic reactor, which is used for the treatment of organic wastewater. The organic wastewater circulates in the IC anaerobic tower, and anaerobic microorganisms are placed in the IC anaerobic tower. The anaerobic microorganisms degrade the organic matter in the organic wastewater into biogas and inorganic matter to achieve the standard discharge of wastewater.

[0003] For example, the Chinese patent with publication number CN216808507U discloses a high-efficiency anaerobic IC tower, which aims to solve the technical problems that it is inconvenient to export the filtered sludge and the efficiency of exporting the filtered wastewater is low under the existing technology. The high-efficiency anaerobic IC tower includes a tower body and a support leg fixedly installed at the bottom of the tower body; a water inlet pipe is fixedly installed on the inner side of the tower body, a water distributor is fixedly installed on one end of the water inlet pipe, a first three-phase separator is fixedly installed on the inner side of the tower body, a second three-phase separator is fixedly installed on the inner side of the tower body, and the second three-phase separator is located above the first three-phase separator, a liquid-gas separator is fixedly installed on the upper end of the tower body, and a mud guide assembly is fixedly installed on the bottom end of the tower body. The high-efficiency anaerobic IC tower only needs to drive the sludge to be exported through the setting of the mud guide assembly, and the separated wastewater is exported and processed through the setting of the water guide assembly, thereby realizing efficient filtration and treatment of the wastewater.

[0004] This patent has some disadvantages when used, such as: the device in this patent sets a water guide component in the middle of the first three-phase separator and the second three-phase separator, and pours out the wastewater. Since the wastewater only passes through the first three-phase separator, the biogas contained in the wastewater will be discharged from the water guide pipe along with the wastewater, resulting in waste of biogas and inconvenience for centralized treatment of biogas. In addition, due to the presence of the water guide component, the device in this patent is prone to generate vortices when working, thereby accelerating the floating of granular sludge, resulting in a large amount of granular sludge in the final treated water, while reducing the granular sludge content in the high-load area at the bottom of the IC anaerobic tower, which reduces the sewage treatment efficiency of the IC anaerobic tower. In view of this, we propose an IC anaerobic tower. Utility Model Content

A plurality of umbrella plate separators 11 are fixed on the top in sequence, a gas collecting chamber 12 is provided on the top of the separation tank 2, a wire mesh demister 13 is installed in the gas collecting chamber 12, a gas collecting pipe 14 with a T-shaped structure is provided directly above the tower body 1, one end of the gas collecting pipe 14 passes through the gas collecting chamber 12 and extends to the inner cavity of the gas collecting chamber 12, the bottom end of the gas collecting pipe 14 passes through the upper surface of the tower body 1 and extends to the gas-liquid separation area in the tower body 1, a trumpet-shaped gas collecting cover 15 is fixed to the bottom end of the gas collecting pipe 14, and a drain pipe 16 is fixed to the bottom of the separation tank 2;

[0042] The barrier mesh plate 17 is fixedly installed between the primary three-phase separator 3 and the secondary three-phase separator 4 and close to the upper position of the primary three-phase separator 3;

[0043] The cleaning component is located directly above the barrier mesh plate 17 and is used to clean the granular sludge remaining on the barrier mesh plate 17. The cleaning component includes:

[0044] The protective cover 18 is arranged at the axial position just above the barrier mesh plate 17. The supporting rods 19 fixed to the inner wall of the tower body 1 are symmetrically fixed on the peripheral side of the protective cover 18. A rotating shaft 20 is rotatably connected just below the protective cover 18, and the top of the rotating shaft 20 passes through the lower surface of the protective cover 18 and extends to the inner cavity of the protective cover 18. A bevel gear 1 21 is coaxially connected to the rotating shaft 20 and located in the position inside the protective cover 18. The peripheral side of the bevel gear 1 21 is meshedly connected with a bevel gear 22. A bearing seat 23 is installed on the top surface of the inner cavity of the protective cover 18, and the rotating shaft 20 is connected to the inner cavity of the protective cover 18. The shaft 20 cooperates with the bearing seat 23, and a bracket 25 is fixed to the outer wall of the tower body 1, and a motor 26 is installed on the bracket 25. The output shaft end of the motor 26 is coaxially connected with the connecting shaft 24, and the other end of the connecting shaft 24 passes through the outer wall of the tower body 1 and extends to the inner cavity of the protective cover 18 and is coaxially connected to the bevel gear 22. A plurality of circumferentially equidistantly distributed fixing plates 27 are fixed on the rotating shaft 20 and located at the outer side of the protective cover 18. The lower surface of the fixing plate 27 is provided with evenly distributed soft brushes, and the bottom end of the soft brush is in contact with the upper surface of the barrier mesh plate 17.

[0045] When the device is in use, sewage is injected into the inner cavity of the tower body 1 through the water inlet pipe 6. The sewage diffuses upward along the bottom edge of the sludge cover 5 and contacts and reacts with the sludge layer in the mixing zone at the lower part of the first reaction zone to complete the full mixing with the granular sludge in the first reaction zone. The mud-water mixture formed in the mixing zone enters the first reaction zone. Under the action of high-concentration sludge, most of the organic matter is converted into biogas. The upward flow of the mixed liquid and the violent disturbance of the biogas cause the sludge in the first reaction zone to expand and fluidize, thereby strengthening the contact between the mud and water surfaces. The sludge thus maintains high activity. As the biogas production increases, a part of the mud-water mixture is lifted by the biogas to the upper primary three-phase separator 3 and is separated in the primary three-phase separator. The first-level filtration and separation is completed under the action of the device 3, wherein the granular sludge and the decomposed organic matter will form flocculent impurities and form sludge again and settle, and the mixed liquid in a small part moves upward and passes through the barrier screen 17. In this process, the barrier screen 17 effectively blocks the granular sludge and large granular impurities, so that the second reaction zone becomes a relatively clear gas-liquid mixture with less suspended matter. Then these gas-liquid mixtures pass through the secondary three-phase separator 4, and are further subdivided under the action of the secondary three-phase separator 4, and the solid impurities therein are screened and settled. At this time, the mixture in the gas-liquid separation zone of the tower body 1 basically does not contain large granular impurities and the granular sludge that floats thereon;

[0046] Then, the gas-liquid separation component is started, the water pump 9 works, and the biogas-containing liquid on the upper layer of the tower body 1 is pumped from the tower body 1 to the inner cavity of the separation tank 2. The liquid is blocked by the baffle 10 and changes its flow direction and moves downward. At this time, the liquid contacts the umbrella plate separator 11 below, and under the action of the umbrella plate separator 11, the gas-liquid separation is completed. The liquid sinks under the action of gravity and is deposited at the bottom of the separation tank 2 and discharged to the outside through the drain pipe 16. The biogas moves upward and passes through the action of the multiple umbrella plate separators 11 above, and is separated from the moisture contained in the gas again. Finally, the biogas enters the gas collecting chamber 12. In this process, a small amount of liquid in the biogas is separated under the action of the wire mesh demister 13. Finally, the separated biogas is discharged from the gas collecting pipe 14 to the outside. It is worth adding that the lower surface of the gas collecting hood 15 does not contact the water surface in the gas-liquid separation area of ​​the tower body 1, and the gas collecting hood 15 is in a suspended state, thereby realizing the collection of biogas at the top of the inner cavity of the tower body 1.

[0047] When it is necessary to clean the stains on the barrier mesh 17, the cleaning component is started, the motor 26 starts working, the output shaft of the motor 26 rotates and drives the connecting shaft 24 to rotate, the connecting shaft 24 drives the bevel gear 22 to rotate, the bevel gear 22 drives the bevel gear 1 21 to rotate, the bevel gear 1 21 drives the rotating shaft 20 to rotate, and the multiple fixed plates 27 on the rotating shaft 20 rotate accordingly, and the soft brush on the lower surface of the fixed plate 27 cleans the mesh on the barrier mesh 17.

[0048] The IC anaerobic tower of the utility model introduces sewage into the tower body 1 through the water inlet pipe 6, accelerates the mixing of sewage with granular sludge through the sludge cover 5, utilizes the primary three-phase separator 3 and the secondary three-phase separator 4 to perform secondary filtration and separation on the sewage in the tower body 1, and by arranging the barrier mesh plate 17, the granular sludge at the bottom of the tower body 1 is blocked, thereby reducing the possibility of sludge leakage, thereby reducing the possibility of accidents; by arranging the gas-liquid separation component, the separation tank 2, the umbrella plate separator 11, the water pipe 8 and the gas collecting cover 15 are used to separate and process the gas-liquid mixture, thereby improving the collection and utilization rate of biogas by the device and reducing energy loss; by arranging the cleaning component and driving it with the motor 26, the fixed plate 27 can drive the soft brush to clean the granular sludge remaining on the barrier mesh plate 17, thereby avoiding serious blockage of the barrier mesh plate 17 and ensuring the treatment efficiency of the device for sewage purification.
