DETAILED DESCRIPTION

[0039] Example 1, as Figure 1-Figure 3As shown, the application provides a CO2 degassing process auxiliary research test device, which comprises a test box 1, a CO2 removal assembly 3 and a flow monitoring assembly 2. Two sets of partitions 101 divide the internal space of the test box 1 into a degassing cavity 102 in the middle and installation cavities 103 on both sides. The test box 1 is provided with a gas inlet pipe 105 and a gas outlet pipe 106 which are in communication with the degassing cavity 102 at the head and tail, a liquid inlet pipe 107 and a liquid outlet pipe 108 which are in communication with the installation cavities 103, and a box cover 104 corresponding to the installation cavities 103 on both sides, which facilitates the maintenance of the equipment in the installation cavities 103. The CO2 removal assembly 3 is provided in multiple sets along the gas flow direction in the degassing cavity 102. Each set of CO2 removal assembly 3 is rotatably penetrated through the two partitions 101. During rotation, CO2 in the internal solution is separated into the degassing cavity 102 by membrane technology and is carried out by the gas flow. The head end of the first set of CO2 removal assembly 3 is connected to the liquid inlet pipe 107 through pipeline one 4, and the tail end of the last set of CO2 removal assembly 3 is connected to the liquid inlet pipe 107 through pipeline two 5. The flow monitoring assembly 2 is connected to the head end and tail end of adjacent two sets of CO2 removal assembly 3 and is located in the installation cavity 103, which monitors the data of the liquid flowing through.

[0040] As shown, Figure 4 The CO2 removal assembly 3 comprises 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 condensed gas with strong polarization, its solubility coefficient in the membrane material is large, so its permeation 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, polyether sulfone membrane and polyimide film, etc. One end of the removal cylinder 301 is provided with a rotating part 302 for driving its rotation and supplying solution, and the other end is provided with a fixed part 303 for rotation connection and supplying solution. The flow monitoring assembly 2 is located between the adjacent two sets of rotating parts 302 / two sets of fixed parts 303, forming an S-shaped liquid flow channel.

[0041] Further, as shown, Figure 5 The rotating part 302 comprises a rotating pipe 302a which is coaxially connected to the removal cylinder 301 and is rotatably arranged on the partition 101. The rotating pipe 302a is connected to the corresponding pipeline one 4 / pipeline two 5 / flow monitoring assembly 2. The outside of the rotating pipe 302a is provided with a gear ring 302b, one side is provided with a motor 302d and a gear 302c connected to the main shaft of the motor 302d. The gear 302c is engaged 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 CO2 in the internal solution has the 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 engages the gear rings 302b on both sides. Therefore, the adjacent removal cylinders 301 rotate synchronously in opposite directions, causing the liquid to be repeatedly mixed forward and backward as it moves along the S-shaped trajectory, which is beneficial for comprehensive CO2 removal.

[0044] It needs to be further said that Figure 5 As shown, the fixing member 303 comprises a rotating seat 303h that is detachably connected to the end of the removal cylinder 301. A sealing seat 303b is rotatably mounted on one side of the rotating seat 303h. A cleaning and stirring element, which seals through the rotating seat 303h and extends into the interior of the removal cylinder 301, is mounted on one side of the sealing seat 303b. A fixing tube 303a is mounted on the other side of the sealing seat 303b. The rotating seat 303h, sealing seat 303b, and fixing tube 303a are connected in series and communicate with the corresponding flow monitoring assembly 2.

[0045] The end of the removal cylinder 301 is engaged 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 solution inside it can be stirred.

[0046] It needs to be further said that Figure 6 As shown, the cleaning and stirring element includes a stirring frame 303c that rotates and extends through a rotating base 303h. The lower end of the stirring frame 303c is equipped with an inlet and outlet head 303g, which is connected to the flow monitoring assembly 2. The upper end is equipped with a mounting frame 303e with a cleaning brush 303f. A leakage slag cover 303d is installed on the side wall. The solution flows into the rotating tube 302a and flows out of the inlet and outlet head 303g, or flows into the inlet and outlet head 303g and flows out of the rotating tube 302a. During the flow, the removal cylinder 301 rotates, the cleaning brush 303f cleans its inner wall, and the leakage slag cover 303d catches dirt accumulated on the carbon dioxide separation membrane. These structures also have a disturbing effect, further mixing the solution. After degassing is completed, the cleaning and stirring element can be removed for cleaning and maintenance.

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

[0048] It should be further noted that the liquid inlet and outlet head 303g is close to the rotating seat 303h, and the flow time of the liquid is prolonged by being away from the rotating tube 302a.

[0049] like Figure 7 As shown, the flow monitoring assembly 2 includes a connecting pipe 201 connecting two adjacent groups of rotating pipes 302a / two groups of fixed pipes 303a; a monitoring box 202 located on the connecting pipe 201; a water pump 203 is provided on the monitoring box 202, and a monitoring probe for monitoring the solution is also provided.

[0050] like Figure 8 As shown, a circulation component 6 is provided between the liquid inlet pipe 107 and the liquid outlet pipe 108; the circulation component 6 includes a connecting pipe 2 601 respectively connected to the liquid inlet pipe 107 and the liquid outlet pipe 108 through a three-way valve; a monitoring box 2 602 is located on the connecting pipe 2 601; a water pump 2 603 is provided on the monitoring box 2 602, and a monitoring probe 2 for monitoring the solution is also provided.

[0051] It should be further explained that monitoring probe 1 and monitoring probe 2 can be temperature monitoring probes and CO2 concentration monitoring probes, which are inserted into the corresponding solution segments to obtain relevant data before and after degassing. By collecting data in segments, the test conditions can be accurately grasped, facilitating timely adjustment of parameters.

[0052] In addition, temperature regulating components are provided in the rotating tube 302a and the fixed tube 303a, such as resistance wires for electric heating and semiconductor refrigeration plates for electric cooling. According to the monitoring results of the temperature monitoring probe, the temperature of the solution is adjusted in sections to keep the temperature stable throughout the process, thereby reducing the impact of temperature on CO2 degassing.

[0053] When the data acquisition end detects that the CO2 degassing is not complete, the circulation component 6 can be started to degas the CO2 multiple times by repeatedly passing the solution into the S-shaped liquid flow channel. During the degassing process, the temperature and gas flow rate are adjusted to conduct auxiliary research on the CO2 degassing process until the test goal is achieved.

[0054] Example 2: Based on the CO2 degassing process auxiliary research test device in Example 1, this example proposes a CO2 degassing process auxiliary research test method, and the method steps are as follows:

[0055] S1. Pre-treat the sample solution in advance. The main pre-treatment methods include filtering to remove impurities, temperature adjustment, etc. At the same time, accelerate gas (such as nitrogen) and connect the gas source to the degassing chamber 102.

[0056] S2, the sample solution enters from the liquid inlet pipe 107 and passes through the rotating and sequentially connected CO2 removal components 3;

[0057] S3, the sample solution moves in an S-shaped track, and the rotation of the removal cylinder 301 can mix the solution, so that the CO2 in the solution has the opportunity to contact the carbon dioxide separation membrane, and the membrane technology repeatedly separates the CO2 in the solution into the degassing cavity 102, and is driven out by the accelerated airflow; in addition, when the removal cylinder 301 rotates, the rotating seat 303h rotates synchronously, the cleaning stirring part is stationary with the sealing seat 303b, and the relative removal cylinder 301 is in a moving state, so that the removal cylinder 301 can be cleaned and the solution inside can be stirred;

[0058] S4, the flow monitoring assembly 2 monitors the data of the liquid flowing through: the monitoring probe one and the monitoring probe two can be temperature monitoring probes and CO2 concentration monitoring probes, which extend into the corresponding section of the solution to obtain relevant data before and after degassing; in addition, temperature adjusting parts are arranged in the rotating pipe 302a and the fixed pipe 303a, and the temperature of the solution is adjusted in sections according to the monitoring results of the temperature monitoring probes; when the data acquisition end collects that the CO2 degassing is not complete, the circulating part 6 can be started, the solution is repeatedly introduced into the S-shaped liquid flow channel, and the CO2 degassing is performed multiple times, and in the degassing process, the CO2 degassing process is assisted by temperature adjustment and gas flow rate adjustment, until the test target is reached.

[0059] S5, the mixed gas capturing CO2 is introduced into a measuring device to measure the captured CO2 data, for example, calcium hydroxide solution, because calcium hydroxide reacts with CO2 to produce a precipitate, the amount of precipitate can be calculated by capturing the amount of precipitate, and the green treatment of CO2 is also realized;

[0060] S6, the captured CO2 data and the collected sample solution data before and after each degassing are used for the auxiliary research of the CO2 degassing process of the sample solution.

[0061] The embodiments of the application are described in detail above in combination with the drawings, but the application is not limited thereto, and various changes can be made within the knowledge of those skilled in the art without departing from the purpose of the application.
