Description

Technical Field

[0001] This utility model relates to the field of oxygen-generating air-cooled tower technology, specifically to an oxygen-generating air-cooled tower nozzle backwashing device. Background Technology

[0002] An oxygen-generating air-cooled tower is a commonly used device in industrial oxygen production systems, primarily used to reduce gas temperature and facilitate effective heat exchange. In the oxygen production process, after compression and heating, the gas needs to be cooled before entering subsequent separation and processing steps. The oxygen-generating air-cooled tower is the key device used to accomplish this cooling process.

[0003] In the existing technology, the spray nozzles of oxygen-generating air-cooled towers cannot effectively perform the function of backwashing the spray head. Therefore, we propose a backwashing device for oxygen-generating air-cooled tower spray nozzles. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a backwashing device for the spray head of an oxygen-generating air-cooled tower, which solves the technical problem that the existing technology cannot better achieve backwashing of the spray head.

[0005] According to one aspect, at least one embodiment of the present invention provides a backwashing device for an oxygen-generating air-cooled tower nozzle, comprising: an air-cooled tower, a support leg fixedly connected to the bottom of the air-cooled tower, a fan provided on the inner side of the air-cooled tower, and a nozzle backwashing device provided on the side of the air-cooled tower. The nozzle backflushing device includes chilled water nozzles, one end of which is connected to the side of an air-cooled tower. A cooling water nozzle is also connected to the side of the air-cooled tower. A heat exchanger is fixedly connected to the inner side of the air-cooled tower. One end of the chilled water nozzle is fixedly connected to a chilled water pipe, and a chilled water flow control valve is installed on the circumference of the chilled water pipe. One end of the cooling water nozzle is fixedly connected to a cooling water pipe, and a cooling water flow control valve is installed on the circumference of the cooling water pipe. Two drain pipes are connected to the side of the chilled water pipe, corresponding to the chilled water pipe and the cooling water pipe respectively. Both drain pipes have chilled water backflushing valves and cooling water backflushing valves on their circumferences. This allows the device to backflush blockages in the chilled water or cooling water nozzles when they become clogged, using the pressure from the drain pipes and the air-cooled tower to restore normal spraying.

[0006] For example, in at least one embodiment of this utility model, a backwashing device for an oxygen-generating air-cooled tower nozzle further includes: a chilled water backwashing valve disposed on the circumferential surface of a drain pipe connected to a chilled water pipe, and a cooling water backwashing valve disposed on the circumferential surface of a drain pipe connected to a cooling water pipe. The function of these cooling water backwashing valves and chilled water backwashing valves is to remove dirt and impurities from the chilled water nozzles and cooling water nozzles, ensuring smooth operation of the chilled water and cooling water systems, and improving equipment efficiency and service life.

[0007] Two heat exchangers are provided, arranged in an array along the longitudinal axis of the air-cooled tower. This dual-array design helps improve heat exchange efficiency, optimize fluid flow, distribute workload, provide redundancy protection, and enhance system stability and reliability.

[0008] The two heat exchangers are located directly below the chilled water nozzle and the cooling water nozzle, respectively, and five support legs are provided. Optimizing heat exchange efficiency, ensuring system stability and reliability, uniform load distribution, and enhancing the structural stability of the equipment are all measures that help improve the operating efficiency of the air-cooled tower and heat exchanger system, extend its service life, and reduce the risk of failure.

[0009] The five supporting legs are arranged in a circumferential array along the bottom of the air-cooled tower, with a gap between the circumferential surfaces of the cooling water pipes and the chilled water pipes. This design enhances the stability of the air-cooled tower through the circumferential array of the five supporting legs, and improves airflow, reduces thermal interference, facilitates installation and maintenance, mitigates the effects of thermal expansion, and prevents condensation on the equipment through the gap between the cooling water pipes and the chilled water pipes, thereby improving the overall system's efficiency, stability, and long-term operational reliability.

[0010] According to another aspect, at least one embodiment of this utility model also provides a backwashing device for the nozzle of an oxygen-generating air-cooled tower, comprising: an anti-clogging device provided on the side of the sewage pipe, the anti-clogging device including a connecting pipe, one end of the connecting pipe being fixedly connected to one end of the sewage pipe, a slot being opened on the side of the connecting pipe, a connecting rod being slidably connected to the inner side of the slot, a rotating shaft being fixedly connected to one end of the connecting rod, a push plate being rotatably connected to the circumferential surface of the rotating shaft, and a main sewage pipe being penetratingly connected to the circumferential surface of the connecting pipe. This anti-clogging device mainly uses structural design, utilizing components such as the slot, connecting rod, and rotating shaft, to automatically clean debris in the sewage pipe, prevent clogging, and ensure the normal operation of the sewage system.

[0011] For example, in at least one embodiment of this utility model, an oxygen-generating air-cooled tower nozzle backwashing device further includes: two push plates, which are symmetrical about the horizontal axis of the rotation shaft. The two symmetrically arranged push plates can apply force evenly, improve cleaning efficiency, maintain equipment balance, and reduce friction and wear, thereby ensuring the normal operation of the sewage pipe and extending the service life of the equipment.

[0012] A sealing ring is fixedly connected to the inner surface of the slot, and the diameter of the sealing ring is the same as the diameter of the slot. The design of the sealing ring ensures the efficient operation, cleanliness, and durability of the sewage system by preventing leakage, reducing friction, and improving sealing performance.

[0013] The circumferential surface of the connecting rod is slidably connected to the sealing ring, and a return torsion spring is fixedly connected to the circumferential surface of the rotating shaft. One end of the return torsion spring is fixedly connected to the side of the push plate. The sliding connection between the return torsion spring and the sealing ring in the overall design provides flexible motion control and a stable sealing effect. The return torsion spring automatically resets the push plate, ensuring that the system maintains a stable working state during operation and avoiding system failures or efficiency reductions caused by the push plate deviating from its position. The sliding connection ensures sealing performance while allowing relative movement of components, reducing friction and wear, and ensuring long-term system operation.

[0014] A limiting plate is fixedly connected to the inner side of the connecting pipe. One end of the limiting plate is located on the displacement trajectory of the push plate, and the diameter of the push plate is the same as the inner diameter of the main drain pipe. The limiting plate restricts the displacement range of the push plate, ensuring that it does not exceed the predetermined trajectory during cleaning, thus preventing excessive movement or damage to the equipment. The design of the push plate's diameter matching the inner diameter of the main drain pipe ensures efficient and uniform cleaning, while minimizing the risk of clogging and improving the system's stability and service life.

[0015] The beneficial effects of the embodiments of this utility model are as follows: 1. In this utility model, the chilled water pipes, chilled water flow control valve, and other components work together to achieve the following: When a chilled water nozzle becomes clogged, the chilled water flow control valve is closed, and the chilled water backflushing valve is opened. The pressure from the drain pipe and the air-cooled tower is used to flush out the blockage in the chilled water nozzle, restoring normal spraying. Similarly, when a cooling water nozzle becomes clogged, the cooling water flow control valve is closed, and the cooling water backflushing valve is opened. The pressure from the drain pipe and the air-cooled tower is used to flush out the blockage in the cooling water nozzle, restoring normal spraying. This achieves the effect of using the drain pipe and the air-cooled tower pressure to flush out the blockage in either the chilled water or cooling water nozzle when it becomes clogged, thus restoring normal spraying.

[0016] 2. In this utility model, the connecting rod, push plate, and other components work together to achieve the following: the operator holds the connecting rod and pushes it, causing the connecting rod to drive the rotating shaft to move horizontally. The horizontal movement of the rotating shaft drives the push plate to move horizontally, thus disengaging the push plate from the limiting plate. The reset torsion spring, through its own torque, drives the push plate to rotate and reset, thereby pushing out the dirt residue in the main sewage pipe. This achieves automatic cleaning of debris in the sewage pipe, preventing blockages and ensuring the normal operation of the sewage system. Attached Figure Description

[0026] like Figures 1-6As shown, it illustrates an oxygen-generating air-cooled tower nozzle backwashing device according to an embodiment of the present invention, including an air-cooled tower 1, a support leg 2 fixedly connected to the bottom of the air-cooled tower 1, a fan provided on the inner side of the air-cooled tower 1, and a nozzle backwashing device 3 provided on the side of the air-cooled tower 1. The nozzle backwashing device 3 includes a chilled water nozzle 31, one end of which is connected to the side of the air-cooled tower 1. A cooling water nozzle 310 is connected to the side of the air-cooled tower 1. A heat exchanger 32 is fixedly connected to the inner side of the air-cooled tower 1. A chilled water pipe 33 is fixedly connected to one end of the chilled water nozzle 31. A chilled water flow control valve 34 is provided on the circumferential surface of the chilled water pipe 33. A cooling water pipe 35 is fixedly connected to one end of the cooling water nozzle 310. A cooling water flow control valve 36 is provided on the circumferential surface of the cooling water pipe 35. A drain pipe 37 is connected to the side of the chilled water pipe 33. There are two drain pipes 37, which correspond to the chilled water pipe 33 and the cooling water pipe 35, respectively. A chilled water backwash valve 38 and a cooling water backwash valve 39 are provided on the circumferential surface of the drain pipe 37. This allows the system to flush out blockages from the chilled water nozzle 31 or cooling water nozzle 310 when the nozzles are clogged, using the pressure from the drain pipe 37 and the air-cooled tower 1, thus restoring the normal spraying function of the chilled water nozzle 31 or cooling water nozzle 310.

[0027] In some examples, the chilled water backflushing valve 38 is located on the circumferential surface of the drain pipe 37 connected to the chilled water pipe 33, and the cooling water backflushing valve 39 is located on the circumferential surface of the drain pipe 37 connected to the cooling water pipe 35. The function of these cooling water backflushing valves 39 and chilled water backflushing valves 38 is to remove dirt and impurities from the chilled water nozzles 31 and cooling water nozzles 310, ensuring smooth operation of the chilled water and cooling water systems and improving equipment efficiency and service life.

[0028] Two heat exchangers 32 are provided, arranged in an array along the longitudinal axis of the air-cooled tower 1. The design of two heat exchangers 32 arranged along the longitudinal axis helps to improve heat exchange efficiency, optimize fluid flow, share the workload, provide redundancy protection, and enhance the stability and reliability of the system.

[0029] Two heat exchangers 32 are located directly below the chilled water nozzle 31 and the cooling water nozzle 310, respectively, and five support legs 2 are provided. Optimizing heat exchange efficiency, ensuring system stability and reliability, even load distribution, and enhancing the structural stability of the equipment are all measures that help improve the operating efficiency of the air-cooled tower 1 and heat exchanger 32 system, extend its service life, and reduce the risk of failure.

[0030] Five support legs 2 are arranged in a circumferential array along the bottom of the air-cooled tower 1, with a gap between the circumferential surface of the cooling water pipe 35 and the circumferential surface of the chilled water pipe 33. This design enhances the stability of the air-cooled tower 1 through the circumferential array of the five support legs 2, and improves air circulation, reduces thermal interference, facilitates installation and maintenance, mitigates the effects of thermal expansion, and prevents condensation on the equipment through the gap between the cooling water pipe 35 and the chilled water pipe 33, thereby improving the overall system efficiency, stability, and long-term operational reliability.

[0031] For example, such as Figures 1-6 As shown, when the chilled water nozzle 31 becomes clogged, the chilled water flow control valve 34 is closed, and the chilled water backflushing valve 38 is opened. The pressure from the drain pipe 37 and the air-cooled tower 1 is used to backflush the blockage in the chilled water nozzle 31, restoring normal spraying. When the cooling water nozzle 310 becomes clogged, the cooling water flow control valve 36 is closed, and the cooling water backflushing valve 39 is opened. The pressure from the drain pipe 37 and the air-cooled tower 1 is used to backflush the blockage in the cooling water nozzle 310, restoring normal spraying.

[0032] like Figures 1-6 As shown, this invention illustrates a backwashing device for an oxygen-generating air-cooled tower nozzle in another embodiment. The device includes an anti-clogging device 5 on the side of a sewage pipe 37. The anti-clogging device 5 includes a connecting pipe 51, one end of which is fixedly connected to one end of the sewage pipe 37. A slot 52 is formed on the side of the connecting pipe 51, and a connecting rod 53 is slidably connected to the inner side of the slot 52. A rotating shaft 54 ​​is fixedly connected to one end of the connecting rod 53, and a push plate 55 is rotatably connected to the circumferential surface of the rotating shaft 54. A main sewage pipe 56 is penetrated through the circumferential surface of the connecting pipe 51. This anti-clogging device 5, through its structural design, utilizes components such as the slot 52, connecting rod 53, and rotating shaft 54 ​​to automatically clean debris from the sewage pipe 37, preventing clogging and ensuring the normal operation of the sewage system. In some examples, two push plates 55 are provided, and the two push plates 55 are symmetrical about the horizontal axis of the rotation axis 54. The two symmetrically arranged push plates 55 can ensure the normal operation of the sewage pipe 37 and extend the service life of the equipment by applying force evenly, improving cleaning efficiency, maintaining equipment balance, and reducing friction and wear.

[0033] A sealing ring 57 is fixedly connected to the inner side of the slot 52, and the diameter of the sealing ring 57 is the same as the diameter of the slot 52. The design of the sealing ring 57 ensures the efficient operation, cleanliness and durability of the sewage system by preventing leakage, reducing friction and improving sealing performance.

[0034] The circumferential surface of the connecting rod 53 is slidably connected to the sealing ring 57, and a return torsion spring 58 is fixedly connected to the circumferential surface of the rotating shaft 54. One end of the return torsion spring 58 is fixedly connected to the side of the push plate 55. The sliding connection between the return torsion spring 58 and the sealing ring 57 in the overall design provides flexible motion control and a stable sealing effect. The return torsion spring 58 automatically resets the push plate 55, ensuring that the system maintains a stable working state during operation and avoiding system failures or efficiency reductions caused by the push plate 55 deviating from its position. The sliding connection ensures sealing performance while allowing relative movement of components, reducing friction and wear, and ensuring long-term system operation.

[0035] A limiting plate 59 is fixedly connected to the inner side of the connecting pipe 51. One end of the limiting plate 59 is located on the displacement trajectory of the push plate 55, and the diameter of the push plate 55 is the same as the inner diameter of the main drain pipe 56. By limiting the displacement range of the push plate 55, the limiting plate 59 ensures that the push plate 55 does not exceed the predetermined trajectory during cleaning, avoiding excessive movement or damage to the equipment. The design that the diameter of the push plate 55 is the same as the inner diameter of the main drain pipe 56 ensures efficient and uniform cleaning, while minimizing the risk of clogging and improving the stability and service life of the system.

[0036] For example, such as Figures 1-6 As shown, the operator holds the connecting rod 53 and applies a certain force to push it. The connecting rod 53, through its linkage with the rotating shaft 54, transmits horizontal movement to the rotating shaft 54, causing it to move along the horizontal axis. This horizontal movement of the rotating shaft 54 ​​further drives the push plate 55 to move horizontally accordingly. The push plate 55, as it moves, disengages from the limiting plate 59 that originally restricted its movement and enters the main drain pipe 56. Simultaneously, the return torsion spring 58, affected by the movement of the push plate 55, begins to generate a counterforce through its own torque, pushing the push plate 55 back to its original position. As the push plate 55 rotates and resets, its tight fit with the inner wall of the main drain pipe 56 effectively pushes out accumulated dirt and debris, ensuring the unobstructed and clean interior of the main drain pipe 56 and preventing blockages or poor drainage due to dirt accumulation.

[0037] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
