Description

Technical Field

[0001] This application relates to the field of oxidation towers, and more particularly to an oxidation tower. Background Technology

[0002] Because natural gas contains hydrogen sulfide, which is harmful to humans and the environment, desulfurization is often necessary. Current natural gas desulfurization methods typically use oxidation towers. Natural gas is transported into the oxidation tower, and an oxidant is introduced through aeration pipes to hydrogenate the sulfide in the natural gas into elemental sulfur, which is then removed. However, the aeration pipes in existing oxidation towers are positioned in a single location, preventing the hydrogen sulfide in the natural gas from undergoing a sufficient oxidation-reduction reaction.

[0003] Regarding the aforementioned technologies, the inventors believe there is a need for an aeration pipe that can promote the full reaction of substances within the oxidation tower. Utility Model Content

[0004] In order to promote sufficient reaction between substances within the oxidation tower, this application provides an oxidation tower.

[0005] The oxidation tower provided in this application adopts the following technical solution:

[0006] An oxidation tower includes an oxidation tower body and an aeration pipe rotatably mounted on the oxidation tower body. The aeration pipe has an air inlet channel, and an aeration assembly communicating with the air inlet channel is provided at the bottom of the aeration pipe. The aeration assembly has aeration channels communicating with the air inlet channel and circumferentially spaced along the axis of the aeration pipe. The aeration assembly includes an aeration disc installed at the bottom of the aeration pipe and aeration branch pipes circumferentially spaced on the aeration disc. The aeration branch pipes are arranged in a one-to-one correspondence with the aeration channels, and the aeration branch pipes are bent and inclined on the aeration disc. The top of the aeration disc is also provided with an upwardly extending stirring blade.

[0007] By adopting the above technical solution, during the use of the oxidation tower, gas is supplied to the main body of the oxidation tower through the air inlet channel of the aeration pipe. Since the bottom of the aeration pipe is equipped with an aeration component and the aeration branch pipe in the aeration component is bent and inclined and arranged on the aeration disc, the gas output from the aeration component can drive the aeration pipe to rotate in the opposite direction of the bending direction of the aeration branch pipe, and at the same time drive the rotation of the stirring fan blades at the top of the aeration disc, thereby achieving the effect of aeration and stirring at the same time in the oxidation tower, effectively ensuring the full reaction of the substances in the oxidation tower.

[0008] Optionally, the aeration pipe includes a fixed pipe and a rotating pipe rotatably mounted on the bottom of the fixed pipe. The rotating pipe includes a connecting pipe connected to the fixed pipe and a functional pipe connected to the bottom of the connecting pipe. The outer diameter of the connecting pipe is smaller than the outer diameter of the functional pipe. The connecting pipe is fitted with a rotating bearing for cooperating with the fixed pipe. A sealing structure is provided between the connecting pipe and the fixed pipe.

[0009] By adopting the above technical solution, the specific structure of the aeration pipe is disclosed. By installing a rotary bearing on the connecting pipe of the rotating pipe to cooperate with the fixed pipe, the rotating pipe can have stable support during rotation, reducing the probability of loosening and ensuring the normal operation of the oxidation tower. The sealing structure between the connecting pipe and the fixed pipe helps reduce the probability of leakage at the connection point, ensuring normal gas output.

[0010] Optionally, the oxidation tower body includes an oxidation tower cover, the oxidation tower cover having an installation through hole for the aeration pipe to pass through, the aeration pipe including a first pipe section arranged at the top of the oxidation tower cover and a second pipe section arranged at the bottom of the oxidation tower cover, a first gear being sleeved on the first pipe section of the aeration pipe, and an auxiliary drive assembly for cooperating with the first gear to assist the rotation of the aeration pipe being provided at the top of the oxidation tower cover.

[0011] By adopting the above technical solution, when the reaction force brought by the gas output from the aeration disc cannot drive the rotating tube to rotate, the rotation of the first gear on the first pipe section can be driven by the auxiliary drive component, thereby driving the rotation of the rotating tube, so that the function of the aeration tube can be implemented normally, thus ensuring the full reaction of the substances in the oxidation tower.

[0012] Optionally, the auxiliary drive assembly includes a mounting bracket slidably mounted on the top surface of the oxidation tower cover, a drive motor mounted on the top surface of the mounting bracket, and a second gear connected to the output shaft of the drive motor and meshing with the first gear. The mounting bracket has an arrangement slot for arranging the second gear.

[0013] By adopting the above technical solution, the specific structure of the auxiliary drive component is disclosed. When the auxiliary rotating tube needs to rotate, the mounting bracket is pushed to slide towards the rotating tube until the second gear meshes with the first gear. Then, the rotation of the second gear is driven by the drive motor, which in turn drives the rotation of the first gear, thereby realizing the rotation of the rotating tube. This helps to ensure the normal rotation of the rotating tube and allows the substances in the oxidation tower to react fully.

[0014] Optionally, the top surface of the oxidation tower cover is provided with a guide slide rail and the guide slide rail is provided with a positioning groove. The bottom of the mounting bracket is provided with a guide slider that cooperates with the guide slide rail. The guide slider is provided with a plunger hole and a ball-head spring plunger is provided at the plunger hole. When the plunger ball of the ball-head spring plunger is engaged with the positioning groove, the first gear meshes with the second gear.

[0015] By adopting the above technical solution, the cooperation between the top guide rail of the oxidation tower cover and the bottom guide slider of the mounting frame provides guidance for the sliding process of the mounting frame, improving the efficiency of the engagement between the first and second gears. The positioning groove on the guide rail and the ball spring plunger on the guide slider help limit the sliding process of the mounting frame. When the ball spring plunger on the guide slider is engaged with the positioning groove of the guide rail, the second gear meshes with the first gear, meaning that it is no longer necessary to push the mounting frame towards the rotating tube, and this also helps reduce the probability of the auxiliary drive component sliding away from the aeration pipe during operation.

[0016] Optionally, the number of guide rails is two.

[0017] By adopting the above technical solution, the setting of two guide rails helps to provide stable guidance for the sliding process of the mounting bracket and reduces the probability of the mounting bracket deviating during the sliding process.

[0018] Optionally, the bottom of the aeration disc is provided with a downwardly extending support column, and the aeration disc is provided with a support assembly at the support column. The support assembly includes a support ring rotatably mounted on the support column and a support foot hinged to the support ring. The end of the support foot away from the support ring abuts against the main body of the oxidation tower.

[0019] By adopting the above technical solution, the specific structure of the support component is disclosed. The setting of support ring and support foot helps to provide support force during the rotation of the aeration pipe, reducing the probability of the rotating pipe of the aeration pipe shifting or loosening during rotation, ensuring the normal operation of the oxidation tower, and effectively ensuring the full reaction between substances in the oxidation tower.

[0020] Optionally, the support ring is provided with at least three support feet at uniform intervals around its circumference.

[0021] By adopting the above technical solution, the support ring is provided with at least three support feet evenly spaced around the circumference, which helps to improve the structural strength of the support component and can effectively improve the stability of the aeration disc, reduce the probability of the aeration disc shifting or loosening during rotation, and ensure the stability of the aeration component during the aeration process.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. An oxidation tower, wherein an aeration component is installed at the bottom of an aeration pipe, and the aeration branch pipes in the aeration component are arranged in a bent and inclined manner so that the gas output from the aeration pipe can drive the rotation of the aeration pipe and at the same time drive the rotation of the stirring fan blades at the top of the aeration disc, so that the oxidation tower can achieve the effect of aeration and stirring at the same time, effectively ensuring the full reaction of the substances in the oxidation tower.

[0024] 2. The cooperation between the first gear on the rotating tube and the auxiliary drive assembly at the top of the oxidation tower cover helps to reduce the occurrence of the rotating tube stopping due to the gas output from the aeration tube failing to drive it to rotate, thus effectively ensuring the full reaction of substances in the oxidation tower.

[0025] 3. By setting a support component at the bottom of the aeration disc, it helps to provide support for the rotating pipe and reduces the probability of the rotating pipe loosening or shifting during rotation. Attached Figure Description

Detailed Implementation

[0034] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0035] This application discloses an oxidation tower. (Refer to...) Figure 1 An oxidation tower includes an oxidation tower body 1 and an aeration pipe 2 rotatably mounted on the oxidation tower body 1. The oxidation tower body 1 includes an oxidation tower cover 11, which has an installation through hole 111 for the aeration pipe 2 to pass through. The oxidation tower body 1 has a variable diameter structure, with the upper part being a larger diameter cylinder and the lower part gradually transitioning to a frustum-cone shape.

[0036] Reference Figure 1 and Figure 2 The aeration pipe 2 has a hollow cylindrical structure and an air inlet channel 21. The aeration pipe 2 includes a fixed pipe 22 and a rotating pipe 23 rotatably mounted on the bottom of the fixed pipe 22. The rotating pipe 23 includes a connecting pipe 231 connected to the bottom of the fixed pipe 22 and a functional pipe 232 connected to the bottom of the connecting pipe 231. The outer diameter of the connecting pipe 231 is smaller than the outer diameter of the functional pipe 232. A rotating bearing 24 is fitted over the connecting pipe 231 to cooperate with the fixed pipe 22, enabling a rotatable connection between the fixed pipe 22 and the rotating pipe 23. To reduce the probability of air leakage at the connection between the fixed pipe 22 and the rotating pipe 23, a sealing structure is provided between the connecting pipe 231 and the fixed pipe 22, located at the bottom of the rotating bearing 24. In this embodiment, the sealing structure is a sealing ring 25.

[0037] Reference Figure 3 and Figure 4An aeration assembly 26 is provided at the bottom of the functional pipe 232 of the aeration pipe 2. The aeration assembly 26 has an aeration channel 261 communicating with the air inlet channel 21, and the aeration channels 261 are arranged circumferentially along the axis of the aeration pipe 2. The aeration assembly 26 includes an aeration disc 262 installed at the bottom of the aeration pipe 2 and aeration branch pipes 263 arranged circumferentially at intervals on the aeration disc 262. The aeration branch pipes 263 are arranged in a one-to-one correspondence with the aeration channels 261, and the aeration branch pipes 263 are bent and inclined on the aeration disc 262, so that when gas is output from the aeration pipe 2, it can drive the aeration pipe 2 to rotate in the opposite direction of the bending direction of the aeration branch pipe 263. To further promote the full reaction of substances within the oxidation tower, agitator blades 27 are installed at the top of the aeration pipe 2 and the aeration disc 262. The agitator blades 27 extend upwards and towards the inner wall of the oxidation tower body 1, allowing for stirring of the solution within the oxidation tower during aeration. In this embodiment, the aeration disc 262 has five aeration channels 261, with one aeration pipe 2 corresponding to each aeration channel 261. Four agitator blades 27 are evenly spaced around the top of the aeration disc 262.

[0038] Reference Figure 1 and Figure 3 To reduce the probability of the rotating tube 23 loosening during rotation, a downwardly extending support column 2621 is provided at the bottom of the aeration disc 262, and a support assembly 3 is provided at the support column 2621 of the aeration tube 2. The support assembly 3 includes a support ring 31 rotatably mounted on the support column 2621 and a support foot 32 hinged to the support ring 31. The end of the support foot 32 away from the support ring 31 abuts against the inner wall of the oxidation tower body 1. To further improve the support effect of the support assembly 3, at least three support feet 32 ​​are evenly spaced circumferentially on the support ring 31, and a suction cup structure 321 is provided on the side of the support foot 32 abutting against the oxidation tower body 1, which helps to reduce the probability of the support foot 32 slipping off the inner wall of the oxidation tower body 1. In this embodiment, three support feet 32 ​​are evenly spaced circumferentially on the support ring 31.

[0039] Reference Figure 1 and Figure 5 To reduce the probability of the rotating tube 23 failing to rotate due to insufficient power from the gas output, an auxiliary drive assembly 4 is provided at the top of the oxidation tower cover 11. The aeration pipe 2 includes a first pipe section 28 arranged at the top of the oxidation tower cover 11 and a second pipe section 29 arranged at the bottom of the oxidation tower cover 11. A first gear 281, which cooperates with the auxiliary drive assembly 4, is fitted onto the first pipe section 28 of the aeration pipe 2 to assist the rotation of the rotating tube 23.

[0040] Reference Figure 6 and Figure 7The auxiliary drive assembly 4 includes a mounting bracket 41 slidably mounted on the top surface of the oxidation tower cover 11, a drive motor 42 mounted on the top surface of the mounting bracket 41, and a second gear 43 connected to the output shaft of the drive motor 42 and meshing with a first gear 281. The output shaft of the drive motor 42 extends downwards, and the mounting bracket 41 has an arrangement slot 411 for accommodating the second gear 43. To guide and position the sliding process of the mounting bracket 41, a sliding plate 12 is provided on the top surface of the oxidation tower cover 11. A guide rail 121 is provided on the top surface of the sliding plate 12, and a positioning groove 1211 is provided at the guide rail 121. The top surface of the mounting bracket 41 has a guide slider 412 that cooperates with the guide rail 121. There are two guide rails 121. The guide slider 412 has a plunger hole 4121, and a ball-head spring plunger 44 is provided within the plunger hole 4121. When the plunger ball 441 of the ball-end spring plunger 44 is engaged in the positioning groove 1211, the first gear 281 meshes with the second gear 43, thereby driving the rotation of the second gear 43 through the drive motor 42. The cooperation between the second gear 43 and the first gear 281 assists in the rotation of the rotating tube 23. In this embodiment, the guide rail 121 is a T-shaped rail, and the guide slider 412 is a T-shaped slider.

[0041] The implementation principle of an oxidation tower according to an embodiment of this application is as follows: During the use of the oxidation tower, gas is supplied to the inner cavity of the oxidation tower body 1 through the air inlet channel 21 of the aeration pipe 2. Since the aeration pipe 2 is provided with an aeration component 26 at the bottom of the rotating pipe 23, and the aeration branch pipe 263 in the aeration component 26 is arranged in a curved and inclined manner, the reaction force brought by the output gas can drive the rotating pipe 23 in the aeration pipe 2 to rotate in the direction away from the curvature of the aeration branch pipe 263. At the same time, the rotation of the aeration disc 262 can drive the rotation of the stirring fan blade 27, so that the oxidation tower can stir the solution in the oxidation tower body 1 while aerating, effectively ensuring the full reaction of the substances in the oxidation tower. In order to reduce the probability of the rotating pipe 23 not being able to rotate due to the power of the gas output, a first gear 281 is provided in the first pipe section 28 of the aeration pipe 2, and an auxiliary drive component 4 is provided on the top of the oxidation tower cover 11 to cooperate with the first gear 281 to assist the rotation of the rotating pipe 23.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
