Description

Technical Field

[0001] The utility model belongs to the technical field of light emitting diodes, and in particular relates to an anaerobic tower capable of improving the degradation rate of sewage. Background Art

[0002] The anaerobic combined bed reactor (UBF) is essentially a combination of an anaerobic biofilter (AF) and an upflow anaerobic sludge reactor (UASB), hence the name UBF reactor. The lower portion of the anaerobic combined bed reactor consists of a suspended sludge layer, while the upper portion is filled with filler. This can be thought of as reducing the filler layer thickness of an upflow anaerobic biofilter. This creates a space between the bottom water distribution system and the filler layer, allowing for the growth and accumulation of suspended granular sludge. This, in turn, constitutes a UASB treatment process. As wastewater passes through the suspended sludge layer and filler layer, organic matter comes into contact with the microorganisms in the granular sludge layer and the filler biofilm, breaking it down.

[0003] In the prior art, the patent announcement number CN214528315U is an integrated device for organic sewage treatment and deodorization. The above patent includes a tower base and a tower body. The tower body is located on the top of the tower base. An anaerobic biological filter tower and an activated carbon adsorption tower are arranged inside the tower body, and the activated carbon adsorption tower is located above the anaerobic biological filter tower. The inner wall of the tower body is fixedly connected with a first porous plate and a second porous plate, and the second porous plate is located directly above the first porous plate. Anaerobic biological filtration towers can remove organic matter through the biodegradation of anaerobic microorganisms, thereby reducing the COD of sewage and improving its biodegradability, which is beneficial to subsequent aerobic biological treatment; the activated carbon filler inside the activated carbon adsorption tower can adsorb and purify odors to achieve gas deodorization. It has a simple structure and can better treat organic sewage while purifying the generated odors, which is more environmentally friendly. However, in actual use, there are still the following shortcomings: From a practical point of view, when treating sewage, the device only relies on its own treatment conditions for treatment, the degradation rate is slow, the treatment effect is poor, it is difficult to meet increasingly stringent environmental protection requirements, and it is impossible to improve the sewage treatment efficiency.

[0004] Therefore, there is a need for an anaerobic tower that can increase the sewage degradation rate to solve the problem of slow sewage treatment efficiency in the prior art. Utility Model Content

[0008] It is further worth mentioning that a first anaerobic zone is formed in the tower body between the mixing section and the first-stage three-phase separator, and a second anaerobic zone is formed between the first-stage three-phase separator and the second-stage three-phase separator.

[0009] It should be further explained that the first riser is arranged to pass through the secondary three-phase separator.

[0010] As a preferred embodiment, the stirring mechanism includes a connecting bearing, which is fixedly mounted on the downcomer and arranged in the first anaerobic zone. A paddle is fixedly connected to the outer surface of the connecting bearing, and the other side of the paddle is fixedly connected to a rotating cylinder and movably arranged in the tower body.

[0019] The present invention will be further described below with reference to the embodiments.

[0020] See also Figure 1-4 The utility model provides an anaerobic tower that can improve the degradation rate of sewage, including a tower body 1, a water inlet pipe 2 is fixedly connected to the bottom of the left side of the tower body 1, a water outlet pipe 3 is fixedly connected to the top of the right side of the tower body 1, an external circulation pipe 101 is fixedly connected to the tower body 1 below the water outlet pipe 3, a cyclone gas-liquid separator 4 is fixedly connected to the top of the tower body 1, an air outlet pipe 401 is fixedly connected to the top of the cyclone gas-liquid separator 4, a mixing part 201 is provided at the bottom of the tower body 1 in communication with the water inlet pipe 2, and a water distributor is provided at the corresponding position of the mixing part 201 202. A downcomer 5 is fixedly connected to the upper portion of the water distributor 202. A stirring mechanism 8 is provided on the downcomer 5 and is arranged at the upper portion of the mixing section 201. A first-stage three-phase separator 6 is installed in the tower body 1 above the stirring mechanism 8. A first rising pipe 601 is installed on the upper portion of the first-stage three-phase separator 6 and passes through the cyclone gas-liquid separator 4. A second-stage three-phase separator 7 is installed in the tower body 1 above the first-stage three-phase separator 6. A second rising pipe 701 is connected to the upper portion of the second-stage three-phase separator 7 and passes through the cyclone gas-liquid separator 4.

[0021] Further as Figure 2 and Figure 3 As shown, it is worth mentioning that the downcomer 5 passes through the primary three-phase separator 6 and the secondary three-phase separator 7 and is arranged in the cyclone gas-liquid separator 4 and is connected. A first anaerobic zone is formed in the tower body 1 between the mixing section 201 and the primary three-phase separator 6, and a second anaerobic zone is formed between the primary three-phase separator 6 and the secondary three-phase separator 7. The first ascending pipe 601 passes through the secondary three-phase separator 7.

[0022] The biogas degraded in the first anaerobic zone and the second anaerobic zone are collected by the primary three-phase separator 6 and the secondary three-phase separator 7 respectively, and the cyclone gas-liquid separator 4 is used to separate the gas and liquid so that the biogas can be discharged. At the same time, it is convenient for the sewage to be fully degraded and treated, and the mixing mechanism 8 is used to improve its degradation efficiency.

[0023] Further as Figure 2 、 Figure 3 and Figure 4 As shown, it is worth mentioning that the stirring mechanism 8 includes a connecting bearing 801, which is fixedly mounted on the downcomer 5 and is arranged in the first anaerobic zone. The outer surface of the connecting bearing 801 is fixedly connected to a paddle 802, and the other side of the paddle 802 is fixedly connected to a rotating cylinder 803 and movably arranged in the tower body 1. There are multiple paddles 802 and they are spirally arranged between the connecting bearing 801 and the rotating cylinder 803. The paddles 802 are made of lightweight material.

[0024] Sewage is injected into the tower body 1 through the water inlet pipe 2 and enters the mixing part 201 through the water distributor 202 into the first anaerobic zone, where it is evenly mixed with the anaerobic granular sludge. Most of the organic matter in the sewage is converted into biogas here. When the biogas rises and passes through the paddle 802, the flow rate changes, which drives the paddle 802 to rotate on the connecting bearing 801, thereby fully stirring the first anaerobic zone and improving the degradation efficiency of the sewage.

[0025] This solution has the following working process: when this device is used, sewage is injected into the tower body 1 through the water inlet pipe 2 and enters the mixing part 201, and enters the first anaerobic zone through the water distributor 202, and is evenly mixed with the anaerobic granular sludge. Most of the organic matter in the sewage is converted into biogas here. When the biogas rises and passes through the blade 802, the flow rate changes, which drives the blade 802 to rotate on the connecting bearing 801, thereby fully stirring the first anaerobic zone and improving the degradation efficiency of the sewage. When the biogas passes through the first three-phase separator 6, the biogas mixture is collected by the gas collecting hood of the first three-phase separator 6 and injected into the cyclone gas through the first rising pipe 601. In the liquid separator 4, the cyclone gas-liquid separator 4 is used to separate the biogas and muddy water, so that the muddy water flows back to the water distributor 202 through the downcomer 5 and is mixed and reacted again, and the biogas is discharged through the outlet pipe 401. The sewage formed by the first anaerobic zone naturally rises to the second anaerobic zone and is evenly mixed with the anaerobic granular sludge again to degrade the remaining organic matter. The formed biogas enters the cyclone gas-liquid separator 4 through the secondary three-phase separator 7 and the second riser 701 for separation and discharge. The muddy water mixture flows back to the water distributor 202 through the downcomer 5, and is degraded by the second anaerobic zone so that the treated sewage passes through the secondary three-phase separator 7 and is discharged at the outlet pipe 3.

[0026] In summary: through the setting of the stirring mechanism 8, in the process of treating sewage in the tower body 1, the gas generated by the first anaerobic zone treatment above the water distributor 202 rises, driving the stirring mechanism 8 to stir the mixed liquid therein, thereby accelerating the reaction efficiency inside it, cooperating with subsequent treatment work, and further accelerating the degradation efficiency of sewage.
