Description

Technical Field

[0001] This utility model belongs to the technical field of gas extraction facilities, specifically relating to a multi-stage adsorption separation device for gas purification. Background Technology

[0002] In gas purification processes in fields such as chemical engineering, environmental protection, and energy, multi-stage adsorption separation equipment is the core device that removes impurity gases step by step through multiple adsorption layers. The uniformity of gas distribution in the adsorption layers directly affects the purification efficiency and adsorbent utilization rate.

[0003] In traditional multi-stage adsorption separation equipment, gas is usually directly introduced into the adsorption layer through a fixed inlet structure. The position and angle of the inlet are fixed, which causes the gas to concentrate and impact the middle area of ​​the adsorption layer, while the gas flow is insufficient in the edge area. This non-uniform gas distribution causes the adsorbent in the middle part of the adsorption layer to reach saturation quickly, while the adsorbent in the edge part remains unsaturated for a long time. This not only seriously reduces the overall utilization rate of the adsorbent, but also leads to frequent adsorbent replacement and increased operating costs. Utility Model Content

[0004] The purpose of this invention is to provide a multi-stage adsorption separation device for gas purification, which can change the airflow direction and blow the gas evenly onto the surface of the adsorption layer, thereby improving the overall utilization rate of the adsorption layer.

[0005] The specific technical solution adopted by this utility model is as follows:

[0006] A multi-stage adsorption separation device for gas purification includes multiple connecting pipes, each with an adsorption layer mounted on its inner wall. Two fixed pipes are mounted between the multiple connecting pipes, and a rotating ring is rotatably connected between the two fixed pipes. An airflow reversing component is provided on the inner side of the rotating ring, and a locking component is provided on the side wall of the rotating ring.

[0007] Furthermore, the airflow reversing assembly includes a circular plate fixedly connected to the inner wall of the right fixed tube. The side wall of the circular plate has a plurality of first air inlets, which are arranged in a ring array with the center point of the circular plate. An adjusting plate is fixedly connected to the inner wall of the rotating ring. The side wall of the adjusting plate has a second air inlet, and the adjusting plate is in contact with the side wall of the circular plate.

[0008] Furthermore, a sealing strip is fitted on the side wall of the adjustment plate at the second air inlet.

[0009] Furthermore, flanges are fixedly connected to the ends of the connecting pipe and the fixed pipe, and the flanges are connected by bolts.

[0010] Furthermore, the locking assembly includes a support plate fixedly connected to the side wall of the swivel ring, a stud threadedly connected to the side wall of the support plate, a handwheel fixedly connected to the end of the stud, and a plurality of positioning holes provided on the side wall of the flange, with the other end of the stud inserted into the positioning hole.

[0011] Furthermore, a sealing ring is fixedly connected to the left end face of the connecting pipe, and a sealing groove is opened on the right end face of the fixed pipe on the right side, and the sealing ring is adapted to the sealing groove.

[0012] Furthermore, the sidewall of the rotating ring is fixedly connected with several anti-slip protrusions.

[0013] The technical effects achieved by this utility model are as follows:

[0014] This invention relates to a multi-stage adsorption separation device for gas purification. By rotating a rotating ring, the connection position between the second air inlet on the adjustment plate and the first air inlet on the circular plate can be adjusted, thereby achieving flexible control of the gas inlet direction. This allows the gas to be uniformly guided to various areas of the adsorption layer, effectively solving the problem of saturation in the middle and unsaturation at the edges of the adsorption layer in traditional equipment, and significantly improving the overall utilization rate of the adsorbent and the gas purification efficiency.

[0022] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0023] like Figures 1-5 As shown, a multi-stage adsorption separation device for gas purification includes multiple connecting pipes 1, each connected pipe 1 having an adsorption layer 2 mounted on its inner wall, two fixed pipes 3 mounted between the multiple connecting pipes 1, and a rotating ring 4 rotatably connected between the two fixed pipes 3. An airflow reversing component is provided on the inner side of the rotating ring 4, and a locking component is provided on the side wall of the rotating ring 4.

[0024] The principle and structure of adsorption layer 2 are existing mature technologies. Different adsorption layers 2 can be replaced according to the actual gas purification requirements or gas characteristics. This part is not the focus of this solution and will not be described in detail here.

[0025] like Figure 3 and Figure 4 As shown, the airflow reversing assembly includes a circular plate 5 fixedly connected to the inner wall of the right fixed pipe 3. The side wall of the circular plate 5 has multiple first air inlets 6, which are arranged in a ring array around the center point of the circular plate 5. An adjusting plate 8 is fixedly connected to the inner wall of the rotating ring 4. The side wall of the adjusting plate 8 has a second air inlet 7, and the adjusting plate 8 is in contact with the side wall of the circular plate 5.

[0026] Specifically, the sidewall of the first air inlet 6 is inclined toward the second air inlet 7 to facilitate gas flow and achieve rapid gas flow. In addition, the number of first air inlets 6 is preferably four, and the number of locking components corresponds to the number of first air inlets 6. When it is necessary to change the gas flow direction, the angle of the rotating ring 4 can be controlled by rotating it by 90°-270° at a time, which is used to increase the contact range between the gas and the adsorption layer 2.

[0027] A sealing strip 14 is fitted on the side wall of the adjusting plate 8 at the second air inlet 7. In order to further increase the sealing between the first air inlet 6 and the second air inlet 7, after rotating the rotating ring 4 to drive the second air inlet 7 to rotate, the sealing strip 14 is located between the first air inlet 6 and the second air inlet 7 to prevent gas leakage.

[0028] like Figures 1-4 As shown, flanges 13 are fixedly connected to the ends of connecting pipe 1 and fixed pipe 3, and the flanges 13 are connected by bolts. The connection method of flanges 13 makes it easy to connect multiple connecting pipes 1 and adsorption layer 2 to achieve multi-stage adsorption. The flanges 13 have reserved holes, which can facilitate bolt connection and use studs 10 for insertion and positioning.

[0029] like Figure 2 and Figure 5 As shown, the locking assembly includes a support plate 9 fixedly connected to the side wall of the rotating ring 4. A stud 10 is threadedly connected to the side wall of the support plate 9. A handwheel 11 is fixedly connected to the end of the stud 10. Several positioning holes 12 are opened on the side wall of the flange 13. The other end of the stud 10 is inserted into the positioning hole 12.

[0030] The locking component can lock the rotating ring 4 to prevent it from shifting due to external force or vibration. On the other hand, it can assist in positioning when rotating the rotating ring 4. For example, after rotating 90°, one of the studs 10 can move from the current positioning hole 12 position to the next positioning hole 12 position.

[0031] like Figure 3 As shown, a sealing ring 15 is fixedly connected to the left end face of the connecting pipe 1, and a sealing groove 16 is opened on the right end face of the right fixed pipe 3. The sealing ring 15 is adapted to the sealing groove 16. After multiple connecting pipes 1 and fixed pipes 3 are connected, the sealing effect can be further enhanced by the sealing ring 15 and the sealing groove 16, thus ensuring the gas purification effect.

[0032] like Figure 1 and Figure 2 As shown, several anti-slip protrusions are fixedly connected to the side wall of the rotating ring 4. The anti-slip protrusions increase the friction between the ring and the hand, making it easier to rotate the rotating ring 4.

[0033] The working principle of this utility model is as follows: When it is necessary to adjust the flow direction of the airflow, first reverse the handwheel 11 to drive the stud 10 to disengage from the positioning hole 12, thereby releasing the lock on the rotating ring 4. Then rotate the rotating ring 4, which drives the adjusting plate 8 to rotate. The adjusting plate 8 drives the second air inlet 7 to rotate, so that the second air inlet 7 is connected to the first air inlet 6 at the designated position. Then, turn the handwheel 11 forward to drive the stud 10 to insert into the positioning hole 12 to lock the rotating ring 4. After the airflow enters the connecting pipe 1, it can be blown onto the adsorption layer 2 in the corresponding area through the first air inlet 6 and the second air inlet 7. Through this adjustment method, the airflow can be blown evenly on the surface of the adsorption layer 2, avoiding the fixed flow of the airflow, which causes the adsorption layer 2 to be saturated in the middle and unsaturated at the edges, thus effectively improving its gas extraction and separation effect.

[0034] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
