Description

Technical Field

[0001] This utility model relates to the field of diversion device technology, and more specifically, to a diversion device for a pressure swing adsorption tower equalization flushing system. Background Technology

[0002] Pressure swing adsorption (PSA) is a separation technology based on the selective adsorption characteristics of adsorbents for different gas components. In processes such as hydrogen purification, oxygen production, or nitrogen production, multiple adsorption towers operate alternately to complete the adsorption, desorption, and regeneration processes. Among these processes, "pressure equalization" is used to transfer high-pressure gas between towers to recover energy, while "rinsing" is used to further desorb residual impurities and ensure sufficient regeneration of the adsorbent. Pressure equalization and rinsing of the PSA towers are key steps to achieve efficient gas separation and adsorbent regeneration. By recovering energy through pressure balance and using product gas or inert gas to remove impurities, the hydrogen recovery rate and purity are improved. At the same time, a flow distribution device is required between multiple PSA towers for flow distribution.

[0003] Most existing pressure swing adsorption tower equalization flushing systems have diversion devices equipped with straight-through connection valves. During use, multiple sets of valves are used for diversion. However, at the moment the equalization valve is opened, the gas from the high-pressure tower often rushes to the low-pressure tower, forming an airflow impact. This impact can cause the adsorbent particles in the adsorption tower to loosen, rub, or even pulverize, shortening the adsorbent's lifespan and causing severe vibrations in the equipment and pipelines, thus affecting its service life.

[0004] In summary, in order to divert the flow in the pressure equalization flushing system of the pressure swing adsorption tower, it is necessary to address the problem that the diverted fluid has a large impact force and is prone to damaging the equipment. The diversion device of the pressure equalization flushing system of the pressure swing adsorption tower should be able to be quickly connected to the pipeline, and slow down the fluid during diversion to improve the service life of the equipment. Utility Model Content

[0005] The problem to be solved by the diversion device of the pressure swing adsorption tower equalization flushing system provided by this utility model is that the existing diversion device of the pressure swing adsorption tower equalization flushing system uses multiple sets of valves to divert the flow. However, the gas in the high-pressure tower often rushes to the low-pressure tower, forming an airflow impact. This impact will cause the adsorbent particles in the adsorption tower to loosen, rub, or even pulverize, shorten the adsorbent life, and cause severe vibration of the equipment and pipelines, affecting the overall service life of the device.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a diversion device for a pressure equalization flushing system of a pressure swing adsorption tower, comprising two mounting sleeves, mounting frames provided on the inner sides of the two mounting sleeves, mounting platforms fixedly connected to the upper and lower ends of the mounting frames, a support platform installed on the outer side of the mounting platforms, a damper body for buffering installed on the inner side of the mounting platforms, a mounting block provided on the damper body, a support spring provided on the outer side of the damper body, a protective tube for protecting the damper body and the support spring installed between the mounting block and the support platform, and a baffle plate for slowing down the flushing fluid provided on the outer side of the mounting block.

[0007] In a preferred embodiment, a splitter body is provided on the outside of the mounting sleeve, a connecting seat is fixedly connected to the outside of the splitter body, a fixing pipe is provided on the outside of the connecting seat, and a first connecting plate is fixedly connected to both the upper and lower ends of the fixing pipe.

[0008] In a preferred embodiment, a support rod is provided on one side of the fixed tube, and a fixing ring is fixedly connected to both the upper and lower ends of the support rod, with the fixing ring rotatably connected to the fixed tube.

[0009] In a preferred embodiment, a rotating platform is rotatably connected to the outer side of the support rod, and mounting rings are provided on both sides of the rotating platform.

[0010] In a preferred embodiment, a second connecting plate is fixedly connected to both the upper and lower ends of the mounting sleeve, a fixing frame is fixedly connected to the inner side of the mounting sleeve, and a limit rod is fixedly connected to the inner side of the fixing frame.

[0011] In a preferred embodiment, a connecting ring is provided on the outer side of the limiting rod, and a limiting hole is provided on the connecting ring. The limiting rod is slidably connected to the limiting hole. A blocking plate is installed on the inner side of the connecting ring, and a fixing block is rotatably connected to the upper end of the blocking plate. The fixing block is threadedly connected to the mounting block.

[0012] In a preferred embodiment, the upper and lower ends of the mounting frame are provided with support frames, the inner side of the support frames is rotatably connected to a rotating frame, and the inner side of the rotating frame is equipped with a spoiler.

[0013] The beneficial effects of this utility model are as follows:

[0014] This invention uses an installation sleeve to install the mounting frame, and utilizes an installation platform and support platform to install and fix the damper body and mounting block. Simultaneously, the damper body and support springs support the mounting block and blocking disc, and the fixing frame and limiting rod facilitate the movement of the blocking disc inside the installation sleeve. During flow diversion, the fluid enters the installation sleeve and impacts the blocking disc, thereby reducing the overall fluid velocity and protecting the flow diversion device and the pressure equalization and flushing system of the side pressure adsorption tower. Furthermore, the support frame and rotating frame facilitate the rotation of the baffle plate, thereby disturbing the entire fluid and improving overall stability and flow diversion effect.

[0015] This utility model uses a diverter body and a connecting seat to connect and fix the pipe, which facilitates the connection and installation of the sleeve for diversion. The fixing pipe is supported by a support rod and a fixing ring for easy overall fixation. At the same time, the installation sleeve is placed on a rotating table and an installation ring, which facilitates the movement of the installation sleeve. Multiple sets of first connecting plates are connected to the connecting seat or second connecting plate by bolts to improve the overall fixation effect and connect to the pressure swing adsorption tower equalization flushing system.

[0026] It is worth noting that the damper body 23 and the support spring 25 support the mounting block 24 and the baffle plate 15. During the diversion, the fluid enters the mounting sleeve 9 and impacts the baffle plate 15, thereby reducing the overall fluid speed, protecting the diversion device and the pressure equalization flushing system of the side pressure adsorption tower, improving the protection effect of the overall equipment, and improving the overall maintainability.

[0027] Referring to the attached drawings in the instruction manual, a splitter body 1 is provided on the outside of the mounting sleeve 9, a connecting seat 2 is fixedly connected to the outside of the splitter body 1, a fixing pipe 3 is provided on the outside of the connecting seat 2, and a first connecting plate 4 is fixedly connected to both the upper and lower ends of the fixing pipe 3.

[0028] It should be noted that the main body 1 of the distributor and the connecting seat 2 are connected to the fixed pipe 3, which facilitates the connection and installation of the sleeve 9, thereby enabling the distribution of the flow.

[0029] Refer to the instruction manual appendix Figure 2 A support rod 5 is provided on one side of the fixed tube 3. The upper and lower ends of the support rod 5 are fixed with a fixing ring 6, which is rotatably connected to the fixed tube 3.

[0039] It is worth noting that the first connecting plate 4 is connected to the connecting seat 2 or the second connecting plate 10 by bolts, thereby improving the overall fixing effect. The two mounting sleeves 9 can be moved as a whole by the mounting ring 8, which facilitates maintenance and replacement and improves the overall loading and unloading stability. At the same time, the baffle 19 receives the decelerated fluid, which facilitates the driving of the rotating frame 18 to rotate, further improving the disturbance effect and enhancing the protection capability.
