Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to an anaerobic reaction tower with good mixing effect. Background Technology

[0002] An anaerobic reactor is a device that uses anaerobic microorganisms to decompose organic matter in an anaerobic environment, thereby achieving wastewater treatment. It is widely used in the treatment of high-concentration organic wastewater.

[0003] The patent with publication number CN218371966U proposes a novel anaerobic reaction tower, which includes a tower body, a gas-liquid separator installed on the upper surface of the tower body, a first separation unit and a second separation unit inside the tower body, which can better block and separate sludge. A water inlet pipe is provided on the surface of the tower body, and a water distributor is rotatably connected to the bottom surface inside the tower body. Several sets of drain outlets are provided on the side of the water distributor. The water inlet pipe is inserted into the water distributor, and a sealed bearing is sleeved on the surface of the water inlet pipe and fixedly connected to the water distributor. A bend is fixedly connected to the end of the water inlet pipe near the water distributor.

[0004] In the above case, wastewater was introduced through a water distributor, and the anaerobic particles floating inside the tower came into contact with and reacted with the wastewater. As a result, not all wastewater would come into sufficient contact with the anaerobic particles, resulting in poor mixing effect of the device. Moreover, after long-term operation, dirt easily accumulated inside the water distributor, causing the device to become blocked and reducing its service life.

[0005] Therefore, this invention provides an anaerobic reaction tower with good mixing effect to meet the requirements. Utility Model Content

[0006] The purpose of this invention is to provide an anaerobic reaction tower with good mixing effect to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an anaerobic reaction tower with good mixing effect, comprising a reaction tank, a water distributor rotatably connected to the bottom of the inner side of the reaction tank, several water outlet holes opened on the outer side of the top of the water distributor, a fixed sleeve rotatably connected to the center of the top of the water distributor, a scraper frame fixedly connected to the outer side of the bottom of the fixed sleeve, a water supply pipe fixedly connected to the bottom of the reaction tank, one end of the water supply pipe inside the reaction tank penetrating the fixed sleeve and extending into the water distributor, mixing components fixedly connected to the upper and lower ends of the inner side of the reaction tank, separators fixedly connected above the two mixing components on the inner side of the reaction tank, a separation tank fixedly connected to the top of the reaction tank, and a first pipe, a return pipe, and a second pipe fixedly connected to the bottom of the separation tank.

Several input pipes are fixedly connected to the inside of the mixing chamber, and an output pipe is fixedly connected to the top of the mixing chamber.

[0011] In a preferred embodiment, the number of input tubes is six, which are arranged in a ring inside the mixing box, and the bottom end of the mixing box has a bottom hole whose position and shape are adapted to the input tubes.

[0012] In a preferred embodiment, a plurality of support rods are fixedly connected to the outer side of the top end of the input pipe, and the top ends of the plurality of support rods are fixedly connected to the same drain sleeve, the top end of which is fixedly connected to the top end of the inner side of the mixing box.

The bottom of the reaction tank is fixedly connected to a motor, the output of which is fixedly connected to the rotating shaft.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This utility model, by setting up a mixing component, allows sewage to enter the input pipe through the bottom hole when it rises. After flowing out from the top of the input pipe, it is guided downward by the guide sleeve, impacting the anaerobic particles at the bottom of the inner side of the mixing tank 7, and then flows out from the discharge pipe. This ensures that all sewage comes into full contact with the anaerobic particles, improving the mixing effect of the device and enhancing its working efficiency.

[0017] This utility model, by setting up a water distributor, a fixing sleeve, and a scraper frame, ensures that when the water distributor rotates, the fixing sleeve remains stationary through a connecting rod, allowing the scraper frame and the water distributor to rotate relative to each other.

[0023] The present invention will be further described below with reference to the embodiments.

[0024] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention; the conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the concept of the present invention are all within the scope of protection claimed by the present invention.

[0025] Please see Figures 1-4This utility model provides an anaerobic reaction tower with good mixing effect, including a reaction tank 1. A water distributor 2 is rotatably connected to the bottom of the inner side of the reaction tank 1. Several water outlet holes 3 are opened on the outer side of the top of the water distributor 2. A fixing sleeve 4 is rotatably connected to the center of the top of the water distributor 2. A scraper frame 5 is fixedly connected to the outer side of the bottom of the fixing sleeve 4. A water supply pipe 6 is fixedly connected to the bottom of the reaction tank 1. One end of the pipe inside the reaction tank 1 passes through the fixing sleeve 4 and extends into the water distributor 2. A mixing unit is fixedly connected to both the upper and lower ends of the inner side of the reaction tank 1. The reaction tank 1 has an LRC30 separator 13 fixedly connected to the inside of the reaction tank 1 above the two mixing components. The fixed sleeve 4 is fixedly connected to the top of the water distributor 2 outside the top of the fixed sleeve 4, and its other end is fixedly connected to the inner wall of the reaction tank 1. The outer side of the scraper frame 5 is tightly fitted to the inner side and bottom of the water distributor 2. The bottom of the water distributor 2 is fixedly connected to the rotating shaft, which is rotatably connected to the bottom of the reaction tank 1. The bottom of the reaction tank 1 is fixedly connected to the PMDC motor, and its output end is fixedly connected to the rotating shaft.

[0026] Wastewater enters the water distributor 2 inside the reaction tank 1 through the water inlet pipe 6, and flows evenly to the bottom of the reaction tank 1 through the water outlet 3 at the top of the water distributor 2. The motor at the bottom of the reaction tank 1 is started to drive the water distributor 2 to rotate. The fixing sleeve 4 is connected to ensure that it does not move. The outer side of the scraper frame 5 is tightly fitted with the inner side and bottom of the water distributor 2. As the water distributor 2 rotates, the scraper frame 5 rotates relative to the water distributor 2, which can scrape off the sludge that may be deposited on the inner wall of the water distributor 2 and prevent internal blockage.

[0027] The fixed sleeve 4 is fixed by a connecting rod connected to the inner wall of the reaction tank 1, ensuring that it remains stationary during the rotation of the water distributor 2. The scraper frame 5 is fixed to the outer side of the bottom end of the fixed sleeve 4. As the water distributor 2 rotates, the scraper frame 5 and the water distributor 2 generate relative movement, which allows the scraper frame 5 to continuously scrape and clean the inner wall of the water distributor 2, keeping the inside of the water distributor 2 clean and unobstructed. This avoids downtime maintenance caused by problems such as blockage of the water distributor 2, thereby extending the overall service life of the device and reducing the maintenance cost and operating risk of the equipment.

[0028] Please see Figures 1-4The top of the reaction vessel 1 is fixedly connected to a separation vessel 15. The bottom of the separation vessel 15 is fixedly connected to a first pipe 16, a return pipe 17, and a second pipe 18. The mixing assembly includes a mixing box 7 fixedly connected to the inside of the reaction vessel 1. The mixing box 7 is filled with anaerobic particles at half its internal capacity. The top of the mixing box 7 is lower than the top of the input pipe 9 and higher than the bottom of the drainage sleeve 11. Several input pipes 9 are fixedly connected to the inside of the mixing box 7. The top of the mixing box 7 is fixedly connected to a discharge pipe 12. There are six input pipes 9, which are arranged in a ring inside the mixing box 7. The bottom of the mixing box 7 has a bottom hole 8 whose position and shape are adapted to the input pipes 9. Several bottom holes are fixedly connected to the outside of the top of the input pipes 9. Support rod 10, the top of several support rods 10 are fixedly connected to the same flow guide sleeve 11, the top of which is fixedly connected to the top of the inner side of the mixing tank 7. The bottom end of pipe 16 penetrates into the interior of the reaction tank 1 and is fixedly connected to the top of the separator 13 located below. The bottom end of pipe 2 18 penetrates into the interior of the reaction tank 1 and is fixedly connected to the top of the separator 13 located above. The bottom end of return pipe 17 penetrates into the interior of the reaction tank 1 and extends to the bottom of the mixing component located below. There are two mixing components and two separators 13, which are staggered. The top of the inner side of the reaction tank 1 is fixedly connected to a defoaming plate 14, and the top of the reaction tank 1 is fixedly connected to a water outlet pipe above the defoaming plate 14.

[0029] As the wastewater flows upward, it enters the inlet pipe 9 inside the mixing tank 7 below through the bottom hole 8. It flows out from the top of the inlet pipe 9 and is guided downward by the inside of the inverted funnel-shaped guide sleeve 11. It impacts the anaerobic particles at the bottom of the mixing tank 7 and reacts with them. Under the action of anaerobic microorganisms, the complex organic matter in the wastewater is decomposed into substances such as methane and carbon dioxide, and biogas is formed. Then, the biogas and wastewater flow out from the discharge pipe 12 and come into contact with the separator 13 below. The biogas is separated and enters the separation tank 15 through the first pipe 16. The wastewater continues to rise and passes through the mixing components and separator 13 above again. After the separator 13 separates the biogas, it enters the separation tank 15 through the second pipe 18. The treated wastewater is then defoamed by the defoaming plate 14 and discharged from the outlet pipe. After gas-liquid separation, the biogas in the separation tank 15 has liquid flowing back to the reaction tank 1 through the return pipe 17, while the gas is discharged from the top to the external receiving structure.

[0030] The inlet pipe 9 is arranged in a ring inside the mixing tank 7, ensuring that the sewage enters the mixing tank 7 evenly. When the sewage reaches the top of the inlet pipe 9, it is guided downward by the guide sleeve 11. The guide sleeve 11, through the structure and position of the inverted funnel, adjusts the flow direction of the sewage, causing it to act on the anaerobic particles at the bottom of the mixing tank 7 in a powerful impact manner. This impact not only allows the sewage to fully contact the anaerobic particles, but also effectively breaks up the agglomeration between the particles, increasing the surface area of ​​the particles and thus providing more reaction sites for the anaerobic reaction. After sufficient contact and reaction with the anaerobic particles, the sewage flows out from the outlet pipe 12 at the top of the mixing tank 7, greatly improving the mixing effect of the device. This allows the organic matter in the sewage to be decomposed by the anaerobic particles more quickly and fully, thereby greatly enhancing the working efficiency of the entire device and improving the effect and speed of sewage treatment.

[0031] The working principle and usage process of this utility model: Wastewater enters the water distributor 2 inside the reaction tank 1 through the water inlet pipe 6, and flows evenly to the bottom of the reaction tank 1 through the water outlet 3 at the top of the water distributor 2. The motor at the bottom of the reaction tank 1 is started to drive the water distributor 2 to rotate. The fixing sleeve 4 is connected to ensure that it does not move. The outer side of the scraper frame 5 is tightly fitted with the inner side of the water distributor 2 and the bottom. As the water distributor 2 rotates, the scraper frame 5 rotates relative to the water distributor 2, which can scrape off the sludge that may be deposited on the inner wall of the water distributor 2 and prevent internal blockage.

[0032] As the wastewater flows upward, it enters the inlet pipe 9 inside the mixing tank 7 below through the bottom hole 8. It flows out from the top of the inlet pipe 9 and is guided downward by the inside of the inverted funnel-shaped guide sleeve 11. It impacts the anaerobic particles at the bottom of the mixing tank 7 and reacts with them. Under the action of anaerobic microorganisms, the complex organic matter in the wastewater is decomposed into substances such as methane and carbon dioxide, and biogas is formed. Then, the biogas and wastewater flow out from the discharge pipe 12 and come into contact with the separator 13 below. The biogas is separated and enters the separation tank 15 through the first pipe 16. The wastewater continues to rise and passes through the mixing components and separator 13 above again. After the separator 13 separates the biogas, it enters the separation tank 15 through the second pipe 18. The treated wastewater is then defoamed by the defoaming plate 14 and discharged from the outlet pipe. After gas-liquid separation, the biogas in the separation tank 15 has liquid flowing back to the reaction tank 1 through the return pipe 17, while the gas is discharged from the top to the external receiving structure.

[0033] The separator 13 described above is prior art disclosed in this utility model and will not be described in detail here.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles of the present invention, the scope of which is defined by the appended claims and their equivalents.
