DETAILED DESCRIPTION

[0039] Embodiment 1, as Figure 1-Figure 3 As shown, the present invention proposes a CO 2 Degassing process auxiliary research test device, including test chamber 1, CO 2 The two sets of partitions 101 divide the internal space of the test box 1 into a degassing chamber 102 in the middle and installation chambers 103 on both sides. The test box 1 is provided with an air inlet pipe 105 and an air outlet pipe 106 connected to the degassing chamber 102, a liquid inlet pipe 107 and a liquid outlet pipe 108 connected to the installation chamber 103, and a box cover 104 corresponding to the installation chambers 103 on both sides, so as to facilitate the maintenance of the equipment in the installation chamber 103. 2 Multiple groups of removal components 3 are arranged along the gas flow direction in the degassing chamber 102, and each group of CO 2 The removal components 3 rotate the baffles 101 that penetrate both sides, and during the rotation process, the CO in the internal solution is removed by membrane technology. 2 Separated into the degassing chamber 102, and driven out by the airflow, the first group of CO 2 The head end of the removal component 3 is connected to the liquid inlet pipe 107 through a pipe 4, and the last group of CO 2 The tail end of the removal component 3 is connected to the liquid inlet pipe 107 through the pipeline 2 5. The flow monitoring component 2 connects two adjacent groups of CO 2 The head end and the tail end of the assembly 3 are removed and located in the installation cavity 103 to monitor the data of the liquid flowing through.

[0040] like Figure 4 As shown, CO 2The removal component 3 includes a removal cylinder 301 with a carbon dioxide separation membrane; the working principle of the carbon dioxide separation membrane is mainly based on the adsorption and permeation characteristics of carbon dioxide on the membrane material; since carbon dioxide is a condensable gas, it has strong polarization and a large solubility coefficient in the membrane material, so its permeability coefficient and separation coefficient are also large. By controlling the temperature, pressure and gas composition of the membrane material, effective separation of carbon dioxide and other gases can be achieved. Commonly used membrane materials include polydimethylsiloxane membrane, poly-4-methyl-1-pentene membrane, polyethersulfone membrane and polyimide film. A rotating part 302 is set at one end of the removal cylinder 301 to drive its rotation and supply solution in and out, and a fixed part 303 is set at the other end to be connected to it for rotation and supply solution in and out; the circulation monitoring component 2 is located between two adjacent groups of rotating parts 302 / two groups of fixed parts 303, forming an S-shaped liquid flow channel.

[0041] It is necessary to further say that Figure 5 As shown, the rotating member 302 includes a rotating tube 302a which is coaxially connected to the removal cylinder 301 and rotatably arranged on the partition 101; the rotating tube 302a is connected to the corresponding pipeline 14 / pipeline 25 / circulation monitoring component 2, a gear ring 302b is arranged on the outside of the rotating tube 302a, and a motor 302d and a gear 302c connected to the main shaft of the motor 302d are arranged on one side; the gear 302c is meshed with the gear ring 302b.

[0042] The motor 302d drives the gear 302c to rotate, and the gear ring 302b drives the removal cylinder 301 to rotate synchronously. The rotation process of the removal cylinder 301 can achieve the purpose of mixing the solution, so that the CO in the internal solution 2 There is an opportunity to contact with the carbon dioxide separation membrane, which is conducive to the comprehensive removal of CO 2。

[0043] It should be further noted that the gear 302c is located between adjacent removal cylinders 301 and meshes with the gear rings 302b on both sides. Therefore, the adjacent removal cylinders 301 rotate synchronously in opposite directions, so that the liquid is repeatedly mixed in both directions during its movement along the S-shaped trajectory, which is beneficial to the comprehensive removal of CO. 2 .

[0044] It is necessary to further say that Figure 5 As shown, the fixing member 303 includes a rotating seat 303h detachably connected to the end of the removal cylinder 301; a sealing seat 303b is rotatably arranged on one side of the rotating seat 303h, a cleaning stirring member that seals and penetrates the rotating seat 303h and extends into the interior of the removal cylinder 301 is arranged on one side of the sealing seat 303b, and a fixing pipe 303a is arranged on the other side. The rotating seat 303h, the sealing seat 303b and the fixing pipe 303a are connected in series in sequence and communicate with the corresponding flow monitoring assembly 2.

[0045] The end of the removal cylinder 301 is snap-connected with the rotating seat 303h, and the rotating seat 303h rotates on the sealing seat 303b. When the removal cylinder 301 rotates, the rotating seat 303h rotates synchronously, and the cleaning stirring member is stationary with the sealing seat 303b and is in motion relative to the removal cylinder 301, so the removal cylinder 301 can be cleaned and the internal solution can be stirred.

[0046] It is necessary to further say that Figure 6 As shown, the cleaning stirring member includes a stirring frame 303c that rotates and penetrates the rotating seat 303h; the lower end of the stirring frame 303c is provided with a liquid inlet and outlet head 303g connected to the circulation monitoring component 2, the upper end is provided with a mounting frame 303e with a cleaning brush 303f, and the side wall is provided with a leakage slag cover 303d; the solution flows in from the rotating tube 302a and flows out from the liquid inlet and outlet head 303g, or flows in from the liquid inlet and outlet head 303g and flows out from the rotating tube 302a. During the flow process, the removal cylinder 301 rotates, the cleaning brush 303f cleans its inner wall, and the leakage slag cover 303d holds the dirt accumulated on the carbon dioxide separation membrane. At the same time, these structures also have the effect of disturbing the flow to further mix the solution. After the degassing is completed, the cleaning stirring member can be taken out for cleaning and maintenance.

[0047] It should be further mentioned that the leakage slag receiving cover 303d is similar to a boat shape, with the concave surface facing downwards, so as to hold the dirt and allow the solution to pass through.

[0051] It should be further noted that the monitoring probe 1 and the monitoring probe 2 can be temperature monitoring probes and CO 2 The concentration monitoring probe is inserted into the corresponding section of the solution to obtain relevant data before and after degassing. By collecting data in sections, the test situation can be accurately grasped, making it easier to adjust parameters in a timely manner.

[0052] In addition, temperature regulating components are arranged in the rotating tube 302a and the fixed tube 303a, such as a resistance wire for electric heating and a semiconductor refrigeration sheet for electric cooling. According to the monitoring results of the temperature monitoring probe, the temperature of the solution is adjusted in stages to make the temperature stable throughout the process, so as to reduce the influence of temperature on CO 2 Effect of degassing.

[0053] The data acquisition end collects CO 2 If the degassing is not complete, the circulation part 6 can be started to repeatedly pass the solution into the S-shaped liquid flow channel to repeatedly circulate the CO 2 Degassing, during the degassing process, the temperature and gas flow rate are adjusted to carry out CO 2 The degassing process assists the study until the test objectives are achieved.
