Description

Technical Field

[0001] The utility model relates to the technical field of adsorption tower pressure equalizing diffusion, and more specifically to an adjustable adsorption tower pressure equalizing diffuser. Background Art

[0002] An adsorption tower is a device used to perform an adsorption process. It is commonly used in industrial processes such as gas separation, purification, and drying, as well as liquid decolorization and deodorization. The working principle of an adsorption tower is to utilize the adsorption capacity of an adsorbent (such as activated carbon or molecular sieve) for specific substances, adsorbing the target component in the mixture onto the adsorbent surface, thereby achieving the purpose of separation or purification.

[0003] The pressure equalizing diffuser of the adsorption tower is an important component in the adsorption tower. Its main function is to promote uniform distribution and diffusion of gas when the adsorption tower performs pressure equalizing operation.

[0004] Existing pressure-equalizing diffusers often suffer from poor adjustability when used within adsorption towers. This is especially true when the tower is tall. If the diffuser is insufficiently long, the diffused gas can be confined to a specific area, preventing the adsorbent above from fully contacting the diffused gas and achieving uniform distribution. This significantly limits its flexibility, leading to uneven gas diffusion, preventing the tower from fully utilizing its performance, and potentially negatively impacting the stability and reliability of the entire process.

[0005] Furthermore, existing diffusers may accumulate impurities, dirt, and particulate matter inside over long periods of use. These substances may originate from tiny particles in the gas, byproducts of chemical reactions, or adsorbent debris. If not cleaned promptly, they will gradually clog the diffuser's pores and channels or alter its internal structure, affecting the uniform diffusion and pressure equalization of the gas, and reducing the efficiency and performance of the adsorption tower. Existing cleaning methods typically involve disassembling the diffuser and then manually cleaning it, which undoubtedly increases the labor intensity of the staff and causes numerous inconveniences in actual use.

[0006] In view of this, we propose an adjustable pressure-equalizing diffuser for the adsorption tower. Utility Model Content

[0007] 1. Technical problems to be solved

[0008] The purpose of the utility model is to provide an adjustable adsorption tower pressure equalizing diffuser to solve the problems raised in the above background technology.

[0009] 2. Technical solution

[0010] An adjustable adsorption tower pressure-equalizing diffuser includes an electric push rod, the output end of which is connected to a fixed box, a fixed circular plate is provided at the bottom of the fixed box, a rotating motor is provided inside the fixed box, the output end of the rotating motor is connected to a cleaning and stirring assembly, the cleaning and stirring assembly includes a transmission rod, the bottom of the fixed circular plate is rotatably connected to a diffusion barrel, and the bottom of the diffusion barrel is rotatably connected to a rotating air inlet pipe.

[0011] Preferably, a third electric push rod is provided on the top of the fixed circular plate, an output end of the third electric push rod is connected to a mounting rod, and a limit rod is provided at the bottom of the mounting rod.

[0012] Preferably, a clamping ring is provided at the bottom of the fixed circular plate, and a ball is provided on the inner wall of the clamping ring.

[0013] Preferably, a support plate and a stirring blade are provided on the circumferential outer wall of the transmission rod, and a second electric push rod is provided on the outer wall of the support plate.

[0014] Preferably, the second output end of the electric push rod is connected to a fixing frame, and a cleaning rubber strip is provided on the side wall of the fixing frame.

[0015] Preferably, a diffusion shell is provided on the circumferential outer wall of the diffusion barrel, and the side walls of the plurality of diffusion shells are inclined. The outer walls of the plurality of diffusion shells are also provided with through openings, and the inner wall of the diffusion barrel is correspondingly provided with a plurality of air outlets.

[0016] 3. Beneficial effects

[0017] Compared with the prior art, the advantages of the present invention are that, when in use, the gas can first be injected from the rotating air inlet pipe, and then the rotation of the rotating motor drives the multiple stirring blades to stir and mix the gas, which can effectively prevent the local concentration of the gas from being too high or too low, thereby making the diffusion process more stable and uniform, and the stirring action can break the laminar flow state of the gas and increase the movement and collision of gas molecules, which is very helpful for the gas to diffuse into the adsorption tower faster. When the diffused gas is discharged, it will be inclined to discharge the airflow through the multiple through-holes on the outside of the diffusion shell. This inclined discharge method can utilize the force of the exhaust airflow to drive the diffusion barrel to rotate, and then the reciprocating motion of the electric push rod can drive the diffusion barrel to move up and down horizontally. In this way, the discharged gas can be more evenly diffused inside the adsorption tower, reducing the uneven diffusion caused by diffusion in one area, and can be flexibly adjusted according to the height of the adsorption tower, significantly improving its flexibility of use.

[0018] When the inside of the diffusion barrel needs to be cleaned, the electric push rod 2 can be used to drive the fixed frame carrying the cleaning rubber strip to move so that the cleaning rubber strip can contact the inner wall of the diffusion barrel. Then the electric push rod 3 is used to drive the limit rod to descend and cooperate with the diffusion shell for limiting. Finally, the cleaning rubber strip is driven by the rotating motor to clean the inner wall of the diffusion barrel. Due to the limitation of the limit rod, the cleaning rubber strip will not drive the diffusion barrel to rotate synchronously due to friction resistance when cleaning the inner wall of the diffusion barrel. The overall cleaning method is relatively simple, which greatly reduces the tediousness caused by personnel cleaning and shortens the time for subsequent maintenance of the diffusion barrel.

[0032] In some embodiments, the second electric push rod 240 can be electrically connected to an external power source using a conductive slip ring to avoid the problem of winding during rotation.

[0033] Furthermore, the output end of the electric push rod 240 is connected to a fixing frame 250 , and a cleaning rubber strip 260 is provided on the side wall of the fixing frame 250 to facilitate cleaning of the inner wall of the diffusion barrel 300 .

[0034] It is worth noting that a diffusion shell 310 is provided on the circumferential outer wall of the diffusion barrel 300, and the side walls of the multiple diffusion shells 310 are all inclined. The outer walls of the multiple diffusion shells 310 are also provided with through openings 311. The inner wall of the diffusion barrel 300 is correspondingly provided with multiple air outlets, which is convenient for inclined discharge of the airflow and provides a certain angle so that it can use this force to drive the diffusion barrel 300 to rotate, further improving its diffusion uniformity.

[0035] In some embodiments: the device can be powered by an external conventional power supply, and the device can be controlled by an external controller, all of which belong to the existing technology.

Needless to say, the content protected by the present invention does not involve improvements to the internal structure and methods.

[0037] Working principle: When in use, the gas can first be injected from the rotating air inlet pipe 320, and then the rotation of the rotating motor 120 drives the multiple stirring blades 270 to stir and mix the gas. This can effectively prevent the local concentration of the gas from being too high or too low, thereby making the diffusion process more stable and uniform, and the stirring action can break the laminar state of the gas and increase the movement and collision of gas molecules, which is very helpful for the gas to diffuse into the adsorption tower faster.

This inclined discharge method can use the force of the exhaust airflow to drive the diffusion barrel 300 to rotate, and then the reciprocating motion of the electric push rod 100 can drive the diffusion barrel 300 to move up and down horizontally. In this way, the discharged gas can be more evenly diffused inside the adsorption tower, reducing the diffusion caused by diffusion in one area. In the case of uneven diffusion, it can be flexibly adjusted according to the height of the adsorption tower, which significantly improves its flexibility of use. When the inside of the diffusion barrel 300 needs to be cleaned, the electric push rod 240 can be used to drive the fixed frame 250 carrying the cleaning rubber strip 260 to move, so that the cleaning rubber strip 260 can contact the inner wall of the diffusion barrel 300, and then the electric push rod 3 280 is used to drive the limit rod 282 to descend, and cooperate with the diffusion shell 310 for limiting. Finally, the cleaning rubber strip 260 is driven by the rotating motor 120 to clean the inner wall of the diffusion barrel 300. Due to the limitation of the limit rod 282, the cleaning rubber strip 260 will not drive the diffusion barrel 300 to rotate synchronously due to friction resistance when cleaning the inner wall of the diffusion barrel 300. The overall cleaning method is relatively simple, which greatly reduces the tediousness caused by personnel cleaning, shortens the time for subsequent maintenance of the diffusion barrel, and improves its maintenance efficiency.
