Abstract
Description
Technical Field
[0001] This utility model relates to the field of carbon capture technology, specifically to an integrated carbon capture device that combines multi-stage membrane separation with chemical adsorption. Background Technology
[0002] The multi-stage membrane separation coupled with chemisorption carbon capture integrated equipment is an advanced carbon capture technology device. It combines multi-stage membrane separation technology with chemisorption method to efficiently capture carbon dioxide (CO2) from industrial waste gas (such as flue gas from coal-fired power plants, steel plants, cement plants, etc.).
[0003] A multi-stage membrane separation coupled with chemisorption carbon capture integrated equipment typically consists of a pretreatment unit, a membrane separation unit, a chemisorption unit, auxiliary equipment, and a control system.
[0004] The chemical adsorption device is filled with chemical adsorbents, which can react chemically or physically with carbon dioxide to separate it from the gas. Over time, the adsorbents become saturated and need to be processed. Replacing the chemical adsorbents requires the regular purchase of new adsorbents, which increases the operating cost of the equipment. At the same time, the waste disposal costs generated during the replacement of the adsorbents also increase the operating cost. Therefore, a multi-stage membrane separation coupled with chemical adsorption carbon capture integrated equipment is proposed. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] This utility model provides a technical solution: a multi-stage membrane separation coupled with chemical adsorption integrated carbon capture device. Please refer to [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3 and Figure 4 ,include:
[0028] The pretreatment device 1, membrane separation device 2, adsorption tower 3 and auxiliary equipment 4 are provided. The adsorption tower 3 is provided with an inner frame 5. The adsorption tower 3 is provided with supports 22 on the upper and lower sides outside the inner frame 5. The inner frame 5 and the supports 22 are movably connected.
[0029] The first servo motor 7 is located inside the adsorption tower 3 at the lower left of the inner frame 5. The output end of the first servo motor 7 is equipped with a drive rod 8, and the upper end of the drive rod 8 is equipped with two steam nozzles 9.
[0030] The second servo motor 10 is located at the upper end of the drive rod 8, away from the end of the first servo motor 7. The output end of the second servo motor 10 is equipped with a drive gear 11, and the lower end of the inner frame 5 is provided with a transmission gear ring 12. The drive gear 11 and the transmission gear ring 12 are meshed and connected.
[0031] Chemical adsorbent 6 is placed inside the inner frame 5.
[0032] Please see Figure 2 , Figure 3 and Figure 4A return spring 13 is provided on one side of the upper end of the drive rod 8. A bracket 15 is provided on the upper end of the return spring 13, and the bracket 15 is fixed to the return spring 13. The return spring 13 is used to lift the bracket 15.
[0033] Please see Figure 2 , Figure 3 and Figure 4 A rotating roller 16 is rotatably mounted inside the upper end of the bracket 15, and a vibrator 14 is provided at the lower end of the bracket 15. The vibrator 14 is fixed to the bracket 15. The vibration generated by the vibrator 14 is transmitted to the bracket 15, and the bracket 15 transmits the vibration to the chemical adsorbent 6 through the rotating roller 16.
[0034] Please see Figure 2 and Figure 4 The adsorption tower 3 is provided with a side door 17 on the right side of the inner frame 5, and the side door 17 is rotatably connected to the adsorption tower 3.
[0035] Please see Figure 2 and Figure 4 The adsorption tower 3 is provided with a second side block 20 and a first side block 18 at the lower end of the side door 17. The second side block 20 is fitted with an adjusting bolt 19 through a threaded connection. The adjusting bolt 19 is used to control the lifting and lowering of the limit plate 21.
[0036] Please see Figure 2 and Figure 4 The upper end of the adjusting bolt 19 is rotatably connected to the limiting plate 21, and the limiting plate 21 is slidably connected to the second side block 20. The limiting plate 21 is used to limit the side door 17.
[0037] This scheme involves connecting and turning on the input end of the steam source and steam nozzle 9. The first servo motor 7 is activated to control the drive rod 8 to rotate towards the chemical adsorbent 6 until it reaches a horizontal parallel position. At this point, the drive gear 11 meshes with the transmission gear ring 12, and the steam nozzle 9 heats the chemical adsorbent 6, causing the adsorbed organic matter to carbonize or volatilize. The second servo motor 10 is activated, causing the drive gear 11 to rotate. The transmission gear ring 12 and the drive gear 11 drive the inner frame 5 to rotate, ensuring sufficient contact between the steam and the chemical adsorbent 6 at different positions. Simultaneously, the vibrator 14 is activated to generate vibration, which is transmitted to the chemical adsorbent 6 through the bracket 15 and the rotating roller 16. The vibration disrupts the agglomeration on the adsorbent surface, making it easier for adsorbate molecules to desorb from the adsorbent surface. The adsorbate molecules gain sufficient energy to desorb from the adsorbent surface, forming gas or vapor. This gas or vapor can be discharged through the outlet of the adsorption tower 3 and subjected to appropriate treatment (such as condensation, absorption, etc.) to recover or process the adsorbate. After heating and regeneration, the adsorption tower 3 needs to be cooled to restore the adsorbent to a suitable operating temperature.
