Description

Technical Field

[0001] This utility model relates to the technical field of ammonia removal devices, specifically an ammonia removal device for coal chemical wastewater. Background Technology

[0002] Coal chemical wastewater is industrial wastewater generated during coal chemical production processes. If this wastewater is discharged without treatment, it will cause pollution of water bodies in different ways and to different degrees, thereby endangering human health and affecting industrial and agricultural production.

[0003] The publication number CN220182856U discloses a novel ammonia removal device for coal chemical wastewater. By rotating the stirring fan blades and pumping air into the stripping space with the combined pump, the air is evenly ejected from the uniform jet nozzle, allowing the ammonia-containing wastewater in the stripping space to fully contact the air, thereby greatly improving the stripping efficiency. The pH value of the wastewater in the stripping space is monitored in real time to optimize the stripping efficiency.

[0004] However, in the aforementioned prior art, when using the stripping method to treat wastewater, the wastewater directly enters the stripping space and accumulates inside the space. Air is sprayed below the stirring fan blades located in the wastewater, resulting in poor stripping efficiency. Furthermore, the accumulation of wastewater inside the stripping space easily leads to the adhesion of scale on the inner wall, requiring manual cleaning, thus making the device less practical.

[0005] Therefore, a coal chemical wastewater ammonia removal device is proposed to solve the problems mentioned above. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example: Please see Figure 1 - Figure 4 The ammonia removal device for coal chemical wastewater in this embodiment includes a cylinder assembly, an air jet assembly, a cleaning assembly, and a packing assembly. The air jet assembly and the cleaning assembly are respectively inserted into the side wall of the cylinder assembly, and the packing assembly is disposed inside the cylinder assembly. The cylinder assembly includes a cylinder body 1, a cylinder cover 2, and a cylinder seat 3. When wastewater is sprayed from inside the cylinder cover 2 into the cylinder body 1, the wastewater will come into contact with the packing assembly as the cylinder body 1 falls. At the same time, the jet assembly located below can blow high-temperature air upward, forming a counter-current flow. The packing assembly can increase the contact area between the wastewater and the high-temperature air inside the cylinder body 1. At this time, the free ammonia in the wastewater will evaporate into the air at the gas-liquid interface, which can effectively prevent the waste liquid from forming a scale layer inside the cylinder assembly and affecting subsequent processing. The overall device is more practical.

[0020] The cleaning assembly includes an insertion box 16 and a scraper 25. A first side hole 15 matching the insertion box 16 is provided on the side wall of the cylinder body 1. A box cover 19 overlaps the upper end of the insertion box 16. A motor 20 is fixedly connected to the upper surface of the box cover 19. The output shaft of the motor 20 passes through the box cover 19 and is fixedly sleeved with a first helical gear. An extension cylinder 17 is fixedly connected to the side wall of the insertion box 16. A transmission groove 18 is provided at the lower end of the extension cylinder 17. The transmission groove 18 communicates with the interior of the insertion box 16, and the transmission groove 18 rotates together with the inner wall of the insertion box 16. A transmission rod 21 is connected, and a second helical gear is fixedly sleeved on the transmission rod 21. The first and second helical gears mesh with each other. An upper connecting shaft 23 is rotatably connected to the inner wall of the transmission groove 18. A worm gear 22 is fixedly sleeved on the upper connecting shaft 23. The front side wall of the transmission rod 21 is provided with helical teeth. The worm gear 22 meshes with the helical teeth of the transmission rod 21. A lower connecting shaft 24 is fixedly connected to the lower end of the upper connecting shaft 23. The lower end of the lower connecting shaft 24 is fixedly connected to the upper end face of the scraper 25. A collection groove 26 is opened inside the cylinder seat 3. After being sprayed, the wastewater falls through the gaps in the packing assembly and eventually collects in the collection tank 26 of the cylinder seat 3. The liquid residue of the wastewater after gas-liquid separation will be temporarily stored in the collection tank 26. To prevent calcium and magnesium ions in hard wastewater from forming carbonate / hydroxide scale in the alkaline environment of the collection tank 26, the motor 20 can be started, causing the output shaft of the motor 20 to drive the first helical gear to rotate. The first helical gear then meshes with the second helical gear, causing the transmission rod 21 to rotate in the inner wall of the transmission tank 18 and the insertion box 16. The helical teeth at the front end of the transmission rod 21 can drive the upper connecting shaft 23 to rotate through meshing with the worm gear 22, which in turn drives the lower connecting shaft 24 and the scraper 25 to rotate in the collection tank 26. The scraper 25 can continuously slide and scrape the material on the inner wall of the collection tank 26 to avoid the formation of a scale layer, reducing labor consumption and making the cleaning of scale easier.

[0021] The packing assembly includes an annular shell 10, a packing layer 13 is provided inside the annular shell 10, a hook ring 14 is provided at the center of the upper end face of the packing layer 13, four limiting blocks 11 are fixedly connected to the side wall of the annular shell 10, and four limiting grooves 12 matching the limiting blocks 11 are opened on the inner wall of the cylinder body 1. By setting up a packing assembly, the wastewater comes into contact with the packing layer 13 inside the annular shell 10 during the spraying and falling process. The jet assembly can pass hot air through the gaps in the packing layer 13 and contact the wastewater, thereby achieving gas-liquid contact between the wastewater and the packing assembly. The setting of the limiting block 11 and the limiting groove 12 allows the annular shell 10 and the internal packing layer 13 to be slidably installed into the inside of the cylinder 1 from the upper opening of the cylinder 1. The hook lifting ring 14 is used to connect with an external crane, so that the external crane can remove the packing assembly from the cylinder assembly and complete the replacement through the connection with the hook lifting ring 14, ensuring that the contact area of ​​the wastewater will not shrink due to the aging of the packing assembly.

[0022] The jet assembly includes an air guide plate 31. The side wall of the cylinder body 1 is provided with a second side hole that matches the air guide plate 31. A gas chamber is provided inside the air guide plate 31. An air inlet is provided on the side wall of the air guide plate 31 that communicates with the gas chamber. Four gas nozzles 32 are inserted into the air guide plate 31. The air inlet ends of the four gas nozzles 32 all penetrate the inner wall of the air guide plate 31 and are located in the gas chamber. By setting up the jet assembly, the external gas pump is connected to the air inlet through the delivery pipe, so that hot air can be delivered into the gas chamber through the air inlet. The air guide plate 31 is inserted into the cylinder 1 through the second side hole and overlaps the inner wall of the cylinder 1. At this time, the four gas nozzles 32 are all facing upward and blow the hot air in the gas chamber upward, thereby realizing the upward flow of hot air in the cylinder 1.

[0023] Among them, the side wall of scraper 25 is slidably connected to the inner wall of collection tank 26, and drain pipe 27 is inserted into the side wall of cylinder seat 3. The other end of drain pipe 27 is connected to the inside of collection tank 26. By installing a drain pipe 27, the wastewater remaining in the collection tank 26 can be directed to the outside and await further treatment.

[0024] The upper end of the cylinder cover 2 is provided with a water inlet pipe hole 8, a water inlet pipe is slidably inserted into the water inlet pipe hole 8, an atomizing nozzle is fixedly installed at the lower end of the water inlet pipe, an exhaust pipe 9 is inserted into the side wall of the cylinder cover 2, and valves are fixedly installed on both the exhaust pipe 9 and the drain pipe 27. Wastewater is atomized inside the cylinder cover 2 through the inlet pipe and atomizing nozzle. The wastewater flows downward under the action of the atomizing nozzle so that it comes into contact with the packing assembly. The valve can open and close the exhaust pipe 9 and the drain pipe 27.

[0025] The cylinder body 1 is fixedly connected to a second connecting ring 5 and a third connecting ring 6, the cylinder cover 2 is fixedly connected to a first connecting ring 4, and the cylinder seat 3 is fixedly connected to a fourth connecting ring 7. The upper end faces of the first connecting ring 4, the second connecting ring 5, the third connecting ring 6 and the fourth connecting ring 7 are all provided with multiple threaded holes 28. Multiple first connecting bolts 29 are provided in the multiple threaded holes 28 of the first connecting ring 4 and the second connecting ring 5, and multiple second connecting bolts 30 are provided in the multiple threaded holes 28 of the third connecting ring 6 and the fourth connecting ring 7. After the cap 2 is placed on the upper end of the cylinder body 1, the first connecting ring 4 and the second connecting ring 5 overlap and the multiple threaded holes 28 correspond one-to-one in the vertical direction. At this time, multiple first connecting bolts 29 can be used to fasten the first connecting ring 4 and the second connecting ring 5 through the corresponding threaded holes 28, thereby achieving a fixed connection of the cap 2 on the upper end of the cylinder body 1. The lower end of the cylinder body 1 and the upper end of the cylinder seat 3 are connected by the third connecting ring 6 and the fourth connecting ring 7, and the third connecting ring 6 and the fourth connecting ring 7 are fastened by multiple second connecting bolts 30, ensuring the overall stability of the cylinder assembly.

[0026] The working principle of the above embodiment is as follows: when wastewater is sprayed from the cylinder cover 2 into the cylinder body 1, the wastewater will come into contact with the packing assembly during the fall of the cylinder body 1. At the same time, the jet assembly located below can blow high-temperature air upward to form a counter-flow. The packing assembly can increase the contact area between the wastewater and the high-temperature air in the cylinder body 1. At this time, the free ammonia in the wastewater will evaporate into the air at the gas-liquid interface, which improves the stripping efficiency and effect of the wastewater. At the same time, it avoids the formation of a scale layer in the cylinder body assembly, which will affect subsequent processing. The overall device is more practical.

[0027] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.

[0028] 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 and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
