Description

Technical Field

[0001] This utility model relates to the field of adsorption tower technology, specifically a multi-stage purification adsorption tower for raw gas. Background Technology

[0002] An adsorption tower is based on the principle of pressure swing adsorption and uses high-quality carbon molecular sieves as adsorbents to extract dry gas from the air under certain pressure.

[0003] The existing adsorption equipment has an air inlet located at the bottom of the adsorption tower and an exhaust outlet located at the top of the adsorption tower. During operation, the air enters the adsorption tower through the air inlet at the bottom of the adsorption tower, and then passes upward through the molecular sieve for adsorption. The finished gas is then directly discharged from the exhaust outlet at the top to achieve continuous production.

[0004] Adsorption towers are large pieces of equipment, and their cylinders are often quite large, which makes them difficult to install and transport. Typically, the components are transported to a designated location and the adsorption tower is installed and fixed using welding. After the project is completed or after a certain period of use, the tower does not have the function of reverse disassembly, making it inconvenient for later relocation and secondary installation and transportation. Therefore, we need a multi-stage purification adsorption tower for raw gas that can be reversibly disassembled. Utility Model Content

A connecting module 8 is provided between the lower cylinder 1 and the upper cylinder 2 for fastening the connection between the lower cylinder 1 and the upper cylinder 2. A support frame 3 is installed at the bottom of the lower cylinder 1, and a bottom support assembly 4 is provided below the lower cylinder 1. An air inlet pipe 9 is installed in the lower middle part of the lower cylinder 1 through the bottom support assembly 4. A core rod assembly 5 is provided at the center of the lower cylinder 1 and the upper cylinder 2, and several molecular sieves 7 located inside the lower cylinder 1 and the upper cylinder 2 are installed on the outside of the core rod assembly 5. A detachable exhaust hood 6 is provided at the top of the upper cylinder 2.

[0026] In this embodiment, as Figure 2 and 5 As shown, the adsorption tower includes a lower cylinder 1 and an upper cylinder 2. The outer diameter of the upper cylinder 2 is smaller than the inner diameter of the upper cylinder 1, allowing the upper cylinder 2 to be inserted into the lower cylinder 1 for transport and disassembly. A connecting module 8 is provided between the lower cylinder 1 and the upper cylinder 2 for fastening the connection between them. The connecting module 8 includes a bushing 81 at the top of the lower cylinder 1 and a ring 82 at the bottom of the upper cylinder 2. The bushing 81 is inserted into the ring 82. Several sealing rings 83 are arranged vertically between the bushing 81 and the ring 82. The interior of the bushing 81 extends from bottom to top. A reinforcing sleeve 84 is inserted into the upper part, and a buckle 85 connected to the reinforcing sleeve 84 is provided above the ring sleeve 82. When installing the lower cylinder 1 and the upper cylinder 2, the operator can install the upper cylinder 2 above the lower cylinder 1, and at the same time use the bushing 81 inserted into the inside of the ring sleeve 82 for limiting. The sealing ring 83 provided inside improves the sealing between the lower cylinder 1 and the upper cylinder 2. Then the operator pushes the reinforcing sleeve 84 upward from the inside of the lower cylinder 1 and uses the buckle 85 to fix it to the top of the reinforcing sleeve 84. The two can be connected with bolts, thereby realizing the fixed connection between the lower cylinder 1 and the upper cylinder 2.

[0027] In this embodiment, as Figure 1 and 6 As shown, a support frame 3 is installed at the bottom of the lower cylinder 1, and a bottom support assembly 4 is provided below the lower cylinder 1.

A pull rod 444 is fixedly disposed at one end of the core post 442, extending through the outside of the housing 441. When the operator holds the pull rod 444, the core post 442 can slide inside the housing 441, thereby allowing the core post 442 to be pulled out from the inside of the lower cylinder 1, releasing the connection between the support ring 42 and the lower cylinder 1. After the operator releases the pull rod 444, the core post 442 can be tightly inserted into the inside of the lower cylinder 1 under the action of the spring 443.

[0029] In this embodiment, as Figure 2 and 6 As shown, an air inlet pipe 9 is installed in the lower middle part of the lower cylinder 1 via a base support assembly 4.

The connecting plate 91 is used to fix and limit the sealing plate 41.

[0030] In this embodiment, as Figure 3 As shown, a core rod assembly 5 is provided at the center of the lower cylinder 1 and the upper cylinder 2. The core rod assembly 5 is composed of multiple sections and includes a support column 51. A threaded connection module 52 is provided in the middle of the support column 51.

[0032] Working principle: When installing the adsorption tower, the support frame 3 is first fixed on the preset platform, then the bottom support assembly 4 is fixed above the support frame 3, the air inlet pipe 9 is installed in the middle of the bottom support assembly 4, then the lower cylinder 1 is fixed on the bottom support assembly 4, and the upper cylinder 2 is fixed above the lower cylinder 1 using the connecting module 8, thereby realizing the assembly and connection of the adsorption tower. The upper cylinder 2 is installed above the lower cylinder 1, and there is more than one upper cylinder 2. A smaller upper cylinder 2 structure can also be set above the upper cylinder 2, thereby realizing the assembly and connection of multi-stage adsorption towers. Finally, the exhaust hood 6 is fixed to the top of the upper cylinder 2. When disassembling or transporting the adsorption tower, the upper cylinder 2 is inserted into the interior of the lower cylinder 1, and the above components are used for quick disassembly, which is more conducive to the transportation and disassembly of the adsorption tower.
