Description

Technical Field

[0001] The present invention relates to the technical field of wastewater treatment equipment, in particular to an ammonia nitrogen wastewater treatment device, and in particular to a treatment method of the ammonia nitrogen wastewater treatment device. Background Art

[0002] Ammonia nitrogen wastewater treatment mainly comes from industries such as fertilizer, coking, petrochemical, pharmaceutical, food, landfill, etc. A large amount of ammonia nitrogen wastewater discharged into the water body will not only cause eutrophication of the water body and cause the water body to be black and smelly, but also increase the difficulty and cost of water treatment, and even have a toxic effect on people and organisms.

[0003] Chinese patent CN111137936B discloses a method for treating ammonia nitrogen wastewater, including A1 pre-treating ammonia nitrogen wastewater; A2 first heat-exchange-treating the pre-treated ammonia nitrogen wastewater, and then performing a concentration and temperature-raising treatment; A3 using a stripping tower to strip the heated ammonia nitrogen wastewater to obtain ammonia-containing steam and deammoniated wastewater; A4 connecting the ammonia-containing steam in step A3 to step A2 to concentrate the ammonia nitrogen wastewater; A5 heating the deammoniated wastewater in step A3 to generate secondary steam and high-temperature deammoniated wastewater, and connecting the secondary steam to the stripping tower to supplement the steam in the stripping tower. The stripping tower in step A3 includes a tank body, a spray device and a steam spray device, and the spray device includes a spray pipe, a spray head rotatably mounted on the end of the spray pipe, and a driving part. The steam spray device includes a steam pipe, a steam spray head rotatably mounted on the end of the steam pipe, and a rotating part. The device has a high deammoniation efficiency.

[0004] Although the above-mentioned device can allow ammonia nitrogen wastewater to enter the tank body through the spray pipe and be sprayed from the top of the tank body from top to bottom by the spray head, at the same time, high-temperature steam is sprayed from the bottom to top through the steam pipe through the steam spray head, so that the ammonia nitrogen wastewater entering the tank body is in countercurrent contact with the steam. Although this convection spraying method can achieve uniform contact between the ammonia nitrogen wastewater and the steam, due to the presence of certain water stains and dirt in the ammonia nitrogen wastewater, the device will cause the spray hole to be blocked when the ammonia nitrogen wastewater passes through the spray head for a long time, which greatly affects the spraying and deammoniation effect of the ammonia nitrogen wastewater. At the same time, the tank body needs to be opened manually for long-term maintenance, which greatly affects the work efficiency. Summary of the invention

[0015] A treatment method for an ammonia nitrogen wastewater treatment device comprises the following steps;

[0016] S1. First, start the entire ammonia nitrogen wastewater treatment device, including the steam nozzle and the one-way rotating spray head. The steam nozzle supplies high-temperature steam through the steam pipe, and rotates and sprays from bottom to top to form an ascending hot steam flow. The one-way rotating spray head is connected to the water pipeline, and rotates and sprays the ammonia nitrogen wastewater from top to bottom to form a countercurrent contact with the ascending steam.

[0017] S2. During the countercurrent contact process between steam and wastewater, the free ammonia in the wastewater volatilizes under the action of high-temperature steam, thereby achieving the removal of ammonia nitrogen.

[0018] S3. According to the detection of the spraying effect of the one-way rotating spray head, if the spraying effect decreases, the one-way rotating spray head needs to be unblocked.

[0019] S4. When unblocking the one-way rotating spray head, stop the one-way rotating spray head and the steam spray head, start the mobile push slide, push the hole unblocking device to the bottom of the one-way rotating spray head, and the hole unblocking device dredges and cleans the water outlet of the one-way rotating spray head by physical means. During this process, the one-way rotating spray head will slowly spray ammonia nitrogen wastewater to cooperate with the hole unblocking device for unblocking and cleaning. After unblocking is completed, the mobile push slide will reset the hole unblocking device to the standby state.

[0020] S5. If the one-way rotating sprinkler head is worn out or needs to be replaced after long-term use, start the sprinkler head unlocking device, which will work synchronously with the hole clearing device to unlock and remove the one-way rotating sprinkler head from the installation position, and install a new sprinkler head in the same position.

[0021] S6. After completing the hole unblocking or replacing the spray head, restart the steam spray head and the one-way rotating spray head to continue the treatment of ammonia nitrogen wastewater.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. In the long-term spraying process of ammonia nitrogen wastewater, the accumulation of water stains and dirt in traditional ammonia nitrogen wastewater treatment devices often leads to blockage of the spray head nozzles, which seriously affects the countercurrent contact effect of wastewater and steam, thereby reducing the ammonia nitrogen removal efficiency. The hole dredging device and the mobile push slide are used to realize the automatic dredging and cleaning of the water outlet holes of the one-way rotating spray head. When the spraying effect is detected to be reduced, the system can automatically start the mobile push slide to push the hole dredging device to the bottom of the one-way rotating spray head for physical dredging. At the same time, the one-way rotating spray head slowly sprays ammonia nitrogen wastewater to cooperate with dredging and cleaning, thereby effectively solving the problem of nozzle blockage and ensuring the stability of the spraying effect and the ammonia nitrogen removal efficiency.

[0024] 2. During the maintenance of traditional ammonia nitrogen wastewater treatment equipment, it is usually necessary to manually open the tank to clean and replace the spray head, which is not only time-consuming and labor-intensive, but also increases operational risks and errors. By designing a nozzle unlocking device, the one-way rotating spray head can be quickly disassembled and replaced. When the spray head is worn out due to long-term use and needs to be replaced, the nozzle unlocking device can work synchronously with the hole dredging device to unlock and remove the one-way rotating spray head from the installation position. At the same time, the new spray head can also be quickly installed in place through the same device. This device greatly improves the efficiency of equipment maintenance, reduces labor costs, and reduces production interruption time caused by maintenance. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0037] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0038] See also Figures 1 to 10 As shown, an ammonia nitrogen wastewater treatment device includes a stable spraying device installed inside a tank body 1, the stable spraying device is arranged directly above a steam nozzle 2, and the stable spraying device includes a one-way rotating spraying head 3, a hole clearing device 4, a nozzle unlocking device 5 and a movable pushing slide 6; the one-way rotating spraying head 3 is installed inside the tank body 1, and the one-way rotating spraying head 3 is connected to a water supply pipeline; the movable pushing slide 6 is installed on the side of the tank body 1, and the movable end of the movable pushing slide 6 extends toward the inside of the tank body 1; the hole clearing device 4 is installed at the movable end of the movable pushing slide 6, and the hole clearing device 4 is used to clear and clean the water outlet hole 323 of the one-way rotating spraying head 3; the nozzle unlocking device 5 is installed on the hole clearing device 4, and the nozzle unlocking device 5 is used to disassemble the one-way rotating spraying head 3.

[0039] The steam nozzle 2 is installed at the bottom of the tank body 1, and high-temperature steam is supplied through the steam pipe, and it rotates and sprays from bottom to top to form an ascending hot steam flow. The one-way rotating spray head 3 is installed directly above the steam nozzle 2, connected to the water pipeline, and is responsible for rotating and spraying the ammonia nitrogen wastewater from top to bottom to form a countercurrent contact with the ascending steam. This design ensures the full mixing and uniform contact of the wastewater and the steam, which is conducive to the volatilization of free ammonia in the wastewater. In order to avoid the problem of nozzle blockage caused by long-term spraying of ammonia nitrogen wastewater, a hole dredging device 4 and a mobile push slide 6 are equipped. The mobile push slide 6 is installed on the side of the tank body 1, and its movable end can be extended into the interior of the tank body 1, and the hole dredging device 4 is carried. After the one-way rotating spray head 3 works for a period of time, the one-way rotating spray head 3 and the steam nozzle 2 both stop working. At the same time, the control system automatically starts the mobile push slide 6 to push the hole dredging device 4 to the bottom of the one-way rotating spray head 3. The hole unclogging device 4 unclogs and cleans the water outlet hole 323 of the spray head by physical means. When the hole unclogging device 4 unidirectionally rotates the spray head 3 during unclogging and cleaning, the unidirectionally rotating spray head 3 will slowly spray the ammonia nitrogen wastewater, and the flowing ammonia nitrogen wastewater will cooperate with the hole unclogging device 4 to dredge and clean, thereby effectively improving the unclogging effect and ensuring that the spraying effect of the unidirectionally rotating spray head 3 is not affected.

[0040] Considering the wear and tear and replacement requirements of the sprinkler head after long-term use, the sprinkler head unlocking device 5 is installed on the hole dredging device 4. When the sprinkler head needs to be replaced, the sprinkler head unlocking device 5 cooperates with the hole dredging device 4 to work synchronously to unlock and remove the one-way rotating sprinkler head 3 from the installation position. At the same time, the new sprinkler head can also be quickly installed in place through the same device without opening the entire tank body 1, thereby greatly saving maintenance time and labor costs. The entire processing process is highly automated. It can be automatically completed through a preset program and control system. This not only improves work efficiency, but also reduces errors and risks caused by human operation.

[0041] The innovative stable spray device design effectively solves the problem of spray hole blockage in traditional spray devices and significantly improves the maintenance efficiency and overall working performance of the equipment.

[0042] See also Figures 1 to 4 As shown, the one-way rotating spray head 3 includes a one-way rotating joint 31 installed on the water supply pipeline, a diffusion spray head 32 is installed on the one-way rotating joint 31, a plurality of water outlet holes 323 are provided on the diffusion spray head 32, a connection bayonet 322 is provided at the connection between the diffusion spray head 32 and the one-way rotating joint 31, and a plurality of limiting docking holes 321 are provided on the side of the diffusion spray head 32.

[0043] Ammonia nitrogen wastewater enters the one-way rotating joint 31 through the water pipeline. When the ammonia nitrogen wastewater passes through the one-way rotating joint 31, the one-way rotating joint 31 will drive the diffusion spray head 32 to start rotating clockwise. As the diffusion spray head 32 rotates, the wastewater is evenly sprayed out through multiple water outlets 323, covering the entire treatment area from top to bottom. This spraying method is conducive to the full mixing and countercurrent contact of wastewater and steam, and promotes the volatilization of free ammonia. In order to avoid clogging of the water outlet 323 after long-term use, when the system detects that the spraying effect decreases or reaches the preset dredging cycle, the control system will start the mobile push slide 6 and push the hole dredging device 4 to the bottom of the diffusion spray head 32. The hole dredging device 4 dredges and cleans the water outlet 323 by physical means. In this process, the diffusion spray head 32 will slowly spray wastewater, cooperate with the dredging device, and improve the dredging effect. The connecting bayonet 322 is used to cooperate with the nozzle unlocking device 5 to unlock the diffusion spray head 32 , and the limiting docking hole 321 is used to cooperate with the hole dredging device 4 to accurately dock the diffusion spray head 32 .

[0044] See also Figures 3 to 5 As shown, the one-way rotating joint 31 includes a one-way limit clamping joint 311 fixedly connected to the water supply pipe, a plurality of movable clamping teeth 3111 are installed on the outer side of the one-way limit clamping joint 311, a limit clamping sleeve 312 is installed on the bottom of the one-way limit clamping joint 311, a plurality of self-rotating guide blades 3121 are arranged inside the limit clamping sleeve 312, a plurality of limit clamping teeth 3122 are arranged on the top of the limit clamping sleeve 312, a plurality of limit installation grooves are arranged on the outer side of the limit clamping sleeve 312, movable clamping blocks 3123 are installed inside the limit installation grooves, and first push springs 3124 are installed between the movable clamping blocks 3123 and the limit installation grooves.

[0045] The one-way rotating spray head 3 is composed of a one-way rotating joint 31 and a diffusion spray head 32. The ammonia nitrogen wastewater enters the one-way rotating joint 31 through the water pipe. When the ammonia nitrogen wastewater passes through the one-way rotating joint 31, due to the design of the one-way limit clamp joint 311, the water flow drives the self-rotating guide blade 3121 to rotate, thereby driving the entire diffusion spray head 32 to start rotating clockwise. As the diffusion spray head 32 rotates, the wastewater is evenly sprayed out through the multiple water outlet holes 323 thereon, forming a covering spray from top to bottom, which is conducive to the full mixing and countercurrent contact of the wastewater and steam.

[0046] The hole dredging device 4 is used to regularly clean the water outlet hole 323 of the diffusion spray head 32 to prevent blockage. When the spraying effect of the diffusion spray head 32 decreases or reaches the preset dredging cycle, the control system starts the mobile push slide 6 to push the hole dredging device 4 to the bottom of the diffusion spray head 32. The working end of the hole dredging device 4 first contacts the outer wall of the diffusion spray head 32 and attempts to dock with the limit docking hole 321. If the limit docking hole 321 is not aligned during the initial contact, the working end of the hole dredging device 4 will rotate counterclockwise, and the diffusion spray head 32 may be driven to rotate by friction. However, due to the design of the limit clamping sleeve 312, the diffusion spray head 32 cannot rotate counterclockwise under the interaction between the limit clamping tooth 3122 and the movable clamping tooth 3111, and remains stationary. The hole dredging device 4 continues to rotate until its working end is aligned with the limit docking hole 321 and inserted to achieve stable docking. After the connection is completed, the hole dredging device 4 starts to physically dredge and clean the water outlet hole 323. At this time, the diffusion spray head 32 will slowly spray waste water, cooperate with the hole dredging device 4, and improve the dredging effect.

[0047] The nozzle unlocking device 5 is used to disassemble and replace the diffusion spray head 32. When the diffusion spray head 32 needs to be replaced, the working end of the nozzle unlocking device 5 passes through the connection bayonet 322 and presses the movable block 3123. The movable block 3123 shrinks and moves toward the inside of the limit installation groove under the action of the first push spring 3124, thereby releasing the limit of the connection bayonet 322 and unlocking the diffusion spray head 32. After unlocking, the nozzle unlocking device 5 cooperates with the hole dredging device 4 to easily disassemble the old diffusion spray head 32, and the new spray head can be quickly installed in place through the same connection bayonet 322 without opening the entire tank body 1, saving maintenance time and labor costs.

[0048] See also Figure 2 and Figure 4 As shown, the hole clearing device 4 includes a mounting base 41 mounted on the mobile pushing slide 6, a limited lifting frame 43 is installed on the mounting base 41, a water guide pipe 44 is installed at the bottom of the mounting base 41, and a first linear driver 42 is also installed on the mounting base 41. The output end of the first linear driver 42 is connected to the limited lifting frame 43, and a docking positioning rotating disk 45 is installed on the limited lifting frame 43. The docking positioning rotating disk 45 is used to position the docking diffusion spray head 32, and a synchronous telescopic cleaning mechanism 46 is installed on the docking positioning rotating disk 45. The synchronous telescopic cleaning mechanism 46 is used to synchronously clean multiple water outlet holes 323.

[0049] The mounting base 41 is mounted on the mobile push slide 6 to provide a stable foundation for the entire dredging device. The limiting lifting frame 43 is connected to the mounting base 41 through the first linear drive 42 to achieve lifting movement to adjust the docking height with the diffusion spray head 32. The first linear drive 42 provides power to push the limiting lifting frame 43 to move up and down on the mounting base 41. The docking positioning rotating disk 45 is mounted on the limiting lifting frame 43, which is used to dock with the diffusion spray head 32 and drive it to rotate synchronously. The synchronous telescopic cleaning mechanism 46 is mounted on the docking positioning rotating disk 45, which includes multiple cleaning elements for synchronously cleaning multiple water outlets 323 on the diffusion spray head 32. The water guide pipe 44 is installed at the bottom of the mounting base 41 to guide the discharge of wastewater or impurities generated during the dredging process.

[0050] When the system detects that the spraying effect decreases or reaches the preset dredging cycle, the control system starts the mobile push slide 6 to push the hole dredging device 4 to the bottom of the diffusion spray head 32. After the mounting base 41 arrives at the specified position with the mobile push slide 6, the first linear driver 42 is started to push the limit lifting frame 43 to rise, so that the docking positioning rotating disk 45 contacts the outer wall of the diffusion spray head 32. If the docking end of the docking positioning rotating disk 45 is not aligned with the limit docking hole 321 during the initial contact, the docking positioning rotating disk 45 will continue to rotate counterclockwise and try to dock with the limit docking hole 321 through friction. Once aligned and inserted into the limit docking hole 321, stable docking is achieved. After the docking is completed, the docking positioning rotating disk 45 will drive the docked diffusion spray head 32 to rotate synchronously clockwise, and when the diffusion spray head 32 rotates clockwise, it will drive the synchronous telescopic cleaning mechanism 46 to start working. The multiple cleaning elements in the cleaning mechanism are synchronously telescoped to physically clean each water outlet 323 on the diffusion spray head 32. During this process, the diffuser spray head 32 will slowly spray wastewater and cooperate with the cleaning mechanism to improve the dredging effect. The wastewater and the cleaned impurities are discharged through the water pipe 44. After the cleaning is completed, the first linear drive 42 drives the limit lifting frame 43 to descend, so that the docking positioning rotating disk 45 is separated from the diffuser spray head 32, and the hole dredging device 4 is reset to the standby state. The device realizes efficient and regular cleaning of the water outlet 323 of the diffuser spray head 32, ensuring the long-term stable operation and spraying effect of the ammonia nitrogen wastewater treatment device.

[0051] See also Figures 6 to 10 As shown, a limit slot 451 is provided on the side of the docking positioning rotating disk 45, a plurality of positioning sensing columns 452 are installed on the docking positioning rotating disk 45, a plurality of insertion holes 453 are provided inside the docking positioning rotating disk 45, and an induction card connection device 455 is also installed on the side of the docking positioning rotating disk 45, and the induction card connection device 455 is used to detect the position of the docking positioning rotating disk 45.

[0052] When the system detects that the spraying effect decreases or reaches the preset dredging cycle, the control system activates the mobile push slide 6 to accurately push the hole dredging device 4 to the bottom of the diffusion spray head 32. At this time, the mounting base 41 firmly supports the entire dredging device to ensure operational stability. The first linear drive 42 is started, pushing the limit lifting frame 43 to rise, so that the docking positioning rotating disk 45 gradually approaches and initially contacts the outer wall of the diffusion spray head 32. If the docking end of the docking positioning rotating disk 45 is not accurately aligned with the limit docking hole 321 of the diffusion spray head 32 during the initial contact, the docking positioning rotating disk 45 will rotate counterclockwise through the built-in rotation drive device 454, and use friction to produce relative movement with the outer wall of the diffusion spray head 32 until the multiple positioning sensing columns 452 thereon are initially aligned with the limit docking hole 321 of the diffusion spray head 32. Once the positioning sensing column 452 is preliminarily aligned with the limit docking hole 321, the inductive clamping device 455 intervenes immediately to detect the position of the docking positioning rotating disk 45 and combine it with the limit clamping groove 451 on its side to achieve more accurate docking correction. This step ensures the stable fit between the docking positioning rotating disk 45 and the diffusion spray head 32, laying the foundation for subsequent cleaning work. After the docking is completed, the docking positioning rotating disk 45 rotates clockwise under the drive of the rotation drive device 454, and this rotation action also drives the docked diffusion spray head 32 to rotate and adjust synchronously.

[0053] See also Figures 8 to 10 As shown, the positioning sensing column 452 is slidably connected to the docking positioning rotating disk 45, a first sliding ball 4521 is provided on the top of the positioning sensing column 452, a first pressure detector 4522 is installed on the positioning sensing column 452, and a second pushing spring 4523 is also installed between the positioning sensing column 452 and the docking positioning rotating disk 45.

[0054] The first linear drive 42 is started, pushing the limit lifting frame 43 upward, so that the docking positioning rotating disk 45 gradually approaches and initially contacts the outer wall of the diffusion spray head 32. The subsequent docking operation provides the necessary initial contact. During the initial contact, if the docking end of the docking positioning rotating disk 45 is not accurately aligned with the limit docking hole 321 of the diffusion spray head 32, the rotary drive device 454 will rotate the docking positioning rotating disk 45 counterclockwise. This allows the docking positioning rotating disk 45 to gradually adjust its position. In this adjustment process, the positioning sensing column 452 plays a key role.

[0055] A first sliding ball 4521 is provided on the top of the positioning sensing column 452, which helps to reduce friction resistance and make the docking process smoother. At the same time, a first pressure detector 4522 is installed on the positioning sensing column 452, which can monitor the pressure change when the positioning sensing column 452 contacts the diffusion spray head 32 in real time. When the positioning sensing column 452 is initially aligned with the limit docking hole 321 of the diffusion spray head 32, the first pressure detector 4522 will capture this signal due to the change in contact area and pressure. In addition, a second push spring 4523 is also installed between the positioning sensing column 452 and the docking positioning rotating disk 45. This spring design can provide a certain buffer and thrust during the docking process to ensure that the positioning sensing column 452 can smoothly enter the limit docking hole 321. Once the positioning sensing column 452 is initially aligned with the limit docking hole 321, the induction card connection device 455 immediately intervenes to achieve stable docking and fitting.

[0056] See also Figures 8 to 10 As shown, the inductive card connection device 455 includes a second linear driver 4551 installed on the limit lifting frame 43, a limit mounting sleeve 4552 is installed on the output end of the second linear driver 4551, a limit plug 4553 is installed on the limit mounting sleeve 4552, a third push spring 4554 is arranged between the limit plug 4553 and the limit mounting sleeve 4552, and a second pressure detector is also installed inside the limit mounting sleeve 4552.

[0057] The limiting insertion rod 4553 matches with the limiting slot 451 of the docking positioning rotating disk 45 .

[0058] When the staff needs to replace the diffusion spray head 32, in order to ensure that the nozzle unlocking device 5 can accurately press the movable block 3123 to achieve the unlocking operation, the positioning sensing column 452 of the docking positioning rotating disk 45 is initially aligned with the limit docking hole 321, and the inductive clamping device 455 is then involved. A limit mounting sleeve 4552 is installed on the output end of the second linear drive 4551, and a limit plug rod 4553 is installed on the limit mounting sleeve 4552. The limit plug rod 4553 matches the limit card slot 451 of the docking positioning rotating disk 45. When the second linear drive 4551 is started, it will push the limit plug rod 4553 to move toward the docking positioning rotating disk 45 until the limit plug rod 4553 is fully inserted into the limit card slot 451. There is a third push spring 4554 between the limit rod 4553 and the limit installation sleeve 4552, which provides additional thrust to ensure that the limit rod 4553 can be firmly inserted into the limit slot 451, so as to achieve stable fit between the docking positioning rotating disk 45 and the diffusion spray head 32. The limit installation sleeve 4552 on the second pressure detector is used to detect the pressure of the third push spring 4554, and whether the limit rod 4553 is engaged with the limit slot 451 of the docking positioning rotating disk 45 is determined based on the pressure value. The inductive engagement device 455 can effectively assist the spray head unlocking device 5 to stably unlock.

[0059] See also Figures 6 to 10 As shown, the synchronous telescopic cleaning mechanism 46 includes a positioning installation tube 461 installed at the bottom of the docking positioning rotating disk 45, a synchronous limiting bucket 462 is slidably installed on the positioning installation tube 461, a limiting slide groove is provided inside the synchronous limiting bucket 462, a lifting ring 4621 is provided at the bottom of the synchronous limiting bucket 462, a convex edge 4622 and a concave edge 4623 are provided at the bottom of the lifting ring 4621, and a telescopic installation strip 463 is installed in the limiting slide groove of the synchronous limiting bucket 462, and a limiting guide column 464 is slidably installed on the telescopic installation strip 463, and one end of the limiting guide column 464 is connected to the docking positioning rotating disk 45 The bottom is fixedly connected, and a fourth push spring 465 is installed between the telescopic mounting strip 463 and the docking positioning rotating disk 45. A plurality of telescopic cleaning brushes 466 are also installed on the telescopic mounting strip 463. One end of the telescopic cleaning brush 466 extends toward the insertion hole 453 of the docking positioning rotating disk 45. The synchronous telescopic cleaning mechanism 46 also includes a guide push ring 467 installed on the limiting lifting frame 43. A guide push rod 4671 is installed on the guide push ring 467. A second sliding ball 4672 is provided on the top of the guide push rod 4671. The second sliding ball 4672 is used to resist the bottom of the lifting ring 4621.

[0060] When the docking positioning rotating disk 45 is docked with the diffusion spray head 32 and is ready for cleaning. When the rotary drive device 454 rotates clockwise, the entire synchronous telescopic cleaning mechanism 46 begins to enter the working state. During the rotation of the docking positioning rotating disk 45, the positioning installation tube 461, the telescopic installation strip 463, the limiting guide column 464 and the synchronous limiting bucket 462 at the bottom thereof will be driven to rotate synchronously. The convex edge 4622 and the concave edge 4623 of the lifting ring 4621 on the synchronous limiting bucket 462 will move along the guide push rod 4671 on the guide push ring 467. The second sliding ball 4672 on the guide push rod 4671 is designed to reduce friction and ensure that the lifting ring 4621 can move up and down smoothly along the guide push rod 4671. When the convex edge 4622 of the lifting ring 4621 contacts the guide push rod 4671, the lifting ring 4621 will be pushed to move upward; and when the concave edge 4623 contacts the guide push rod 4671, the lifting ring 4621 will fall. This lifting movement will further push the synchronous limit bucket 462 to rotate synchronously. The lifting movement of the synchronous limit bucket 462 will drive the multiple telescopic mounting strips 463 inside it to synchronously contract or stretch along the limiting guide column 464. In this process, the telescopic mounting strip 463 will squeeze or release the fourth push spring 465, and the elastic force of the spring is used to reset the telescopic mounting strip 463. The movement of the telescopic mounting strip 463 will drive the multiple telescopic cleaning brushes 466 to move synchronously. These cleaning brushes will pass through the insertion hole 453 of the docking positioning rotating disk 45 and extend into the water outlet hole 323 of the diffusion spray head 32. During the reciprocating telescopic movement, the telescopic cleaning brush 466 will generate friction with the inner wall of the water outlet 323, thereby achieving an effective cleaning effect. This friction cleaning can remove the blockage in the water outlet 323 and ensure that the spraying effect is not affected. The synchronous telescopic cleaning mechanism 46 achieves effective cleaning of the water outlet 323 of the diffusion spray head 32 through precise mechanical linkage and ingenious design. It effectively improves the cleaning efficiency and ensures the stability and durability of the spraying effect.

[0061] See also Figure 6 and Figure 8 As shown, the nozzle unlocking device 5 includes a bidirectional ball screw slide 51 installed on the limit lifting frame 43, and the movable ends of the bidirectional ball screw slide 51 are both installed with a sliding abutment frame 52, and the side of the sliding abutment frame 52 is provided with a pressing block 53.

[0062] When the diffusion spray head 32 needs to be replaced, the control system will issue an unlocking command. At this time, the nozzle unlocking device 5 is in a standby state, the movable end of the two-way ball screw slide 51 has been installed with the sliding resistance frame 52, and the side pressure block 53 of the sliding resistance frame 52 is ready. The control system activates the two-way ball screw slide 51, and the two-way ball screw slide 51 starts to work, and its movable end drives the sliding resistance frame 52 to move along the screw direction. During the movement of the sliding resistance frame 52, the pressure block 53 on its side gradually approaches the movable block 3123 on the diffusion spray head 32. When the pressure block 53 contacts the movable block 3123, the sliding resistance frame 52 continues to move, and the pressure block 53 will apply a certain pressure to the movable block 3123. This pressure will cause the movable block 3123 to move toward the inside of the limiting clamp sleeve 312. When the movable block 3123 moves, the hole clearing device 4 drives the diffusion spray head 32 to move downward, so that the diffusion spray head 32 and the one-way rotating joint 31 are separated from each other to achieve unlocking and disassembly.

[0063] A treatment method for an ammonia nitrogen wastewater treatment device comprises the following steps;

[0064] S1. First, start the entire ammonia nitrogen wastewater treatment device, including the steam nozzle 2 and the one-way rotating spray head 3. The steam nozzle 2 supplies high-temperature steam through the steam pipe, and rotates and sprays from bottom to top to form an ascending hot steam flow. The one-way rotating spray head 3 is connected to the water pipeline, and rotates and sprays the ammonia nitrogen wastewater from top to bottom to form a countercurrent contact with the ascending steam.

[0065] S2. During the countercurrent contact process between steam and wastewater, the free ammonia in the wastewater volatilizes under the action of high-temperature steam, thereby achieving the removal of ammonia nitrogen.

[0066] S3. According to the detection of the spraying effect of the one-way rotating spray head 3, if the spraying effect is reduced, the one-way rotating spray head 3 needs to be unblocked.

[0067] S4, when unblocking the one-way rotating spray head 3, stop the one-way rotating spray head 3 and the steam spray head 2, start the mobile pushing slide 6, push the hole unblocking device 4 to the bottom of the one-way rotating spray head 3, and the hole unblocking device 4 dredges and cleans the water outlet hole 323 of the one-way rotating spray head 3 by physical means. During this process, the one-way rotating spray head 3 will slowly spray ammonia nitrogen wastewater to cooperate with the hole unblocking device 4 for unblocking and cleaning. After unblocking is completed, the mobile pushing slide 6 resets the hole unblocking device 4 to the standby state.

[0068] S5. If the one-way rotating sprinkler head 3 is worn out or needs to be replaced after long-term use, the sprinkler head unlocking device 5 is started, and the sprinkler head unlocking device 5 works synchronously with the hole dredging device 4 to unlock and remove the one-way rotating sprinkler head 3 from the installation position, and install a new sprinkler head in the same position.

[0069] S6. After the hole is dredged or the spray head is replaced, the steam spray head 2 and the one-way rotating spray head 3 are restarted to continue the treatment of the ammonia nitrogen wastewater.

[0070] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
