In all examples shown and discussed here, any specific value should be interpreted as being merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, and therefore, once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0028] like Figure 1 As shown, the present application provides a flue gas treatment device, and an embodiment of the flue gas treatment device includes: an absorption tower 10, a pump body 21 and a vibrating member 22. The absorption tower 10 includes a tower body 11 and a packing layer 12 arranged in the tower body 11, and the tower body 11 is provided with a flue gas inlet 13, a flue gas outlet 14, a liquid inlet 15 and a liquid outlet 16 at intervals. The pump body 21 is connected to the liquid outlet 16. The first end of the vibrating member 22 is connected to the pump body 21, and the second end of the vibrating member 22 is inserted into the tower body 11 and connected to the packing layer 12.

[0029] Applying the technical solution of this embodiment, the flue gas treatment device includes: an absorption tower 10, a pump body 21 and a vibrating member 22. The first end of the vibrating member 22 is connected to the pump body 21, and the second end of the vibrating member 22 is inserted into the tower body 11 and connected to the packing layer 12. In this way, when the pump body 21 is working, it generates vibration, and the vibration energy can be transferred to the packing layer 12 through the vibrating member 22, so as to promote the distribution of carbonic anhydrase in the packing layer 12. In this way, the energy generated by the vibration of the pump body when working is fully recovered, and the waste of energy is avoided. Therefore, the technical solution of this embodiment effectively solves the problem of energy waste caused by the vibration of the pump body when working in the related art.

[0030] It should be noted that the application of carbonic anhydrase in the field of carbon dioxide capture mainly depends on its ability to catalyze the hydration reaction of carbon dioxide to produce bicarbonate. The use of carbonic anhydrase in carbon dioxide capture is as follows: carbonic anhydrase is added to the packing layer of the absorption tower in the form of an immobilized mesh reactor. This design allows carbonic anhydrase to fully contact with the reaction liquid and gas, while achieving separation from the packing and reaction liquid, which is convenient for recycling.

[0031] like Figure 1As shown, the flue gas treatment device also includes a bracket 23 arranged on the outside of the tower body 11 and a protective cover 24 arranged on the bracket 23, and the protective cover 24 is sleeved on the outside of the vibrating member 22. The bracket 23 can support the protective cover 24, so that the protective cover 24 can protect the vibrating member 22 from mechanical damage and corrosion, while ensuring the effective transmission of vibration energy. The protective tube is made of high-strength, chemically resistant material, and the interior is smooth to reduce the loss that may be generated by the vibrating member 22 during the vibration transmission process.

[0032] like Figure 1 As shown, in order to facilitate the acquisition of the concentration of carbon dioxide in different areas of the packing layer 12, the flue gas treatment device further includes a plurality of carbon dioxide sensors 31 disposed at different positions of the packing layer 12, and the plurality of carbon dioxide sensors 31 can detect the concentration of carbon dioxide in different areas of the packing layer 12. The flue gas treatment device further includes an adjustment member 40 disposed on the bracket 23, and the adjustment member 40 is in abutment with the vibrating member 22. The adjustment member 40 is used to adjust the vibration frequency of the vibrating member 22 to promote uniform distribution of carbonic anhydrase.

[0033] It should be noted that when the carbonic anhydrase sensor detects the distribution of carbonic anhydrase on the packing layer, it mainly indirectly infers the activity and distribution of carbonic anhydrase by measuring the change in the concentration of carbonic acid in the area. The principle is that carbonic anhydrase is an enzyme that can accelerate the reaction of carbonic acid with water to form carbonic acid. When carbonic anhydrase catalyzes the reaction, it consumes carbon dioxide. The carbon dioxide sensor detects the concentration of carbon dioxide. If the carbonic anhydrase activity in a certain area of ​​the packing layer is high, the concentration of carbon dioxide in this area will be relatively low because carbon dioxide is converted into carbonic acid.

[0034] like Figure 1 As shown, in order to adapt to the characteristics of different packing layers and the distribution requirements of carbonic anhydrase, the vibrating member 22 includes a vibrating rod, and the adjusting member 40 is movably arranged along the axial direction of the vibrating rod. The adjusting member 40 includes a mounting tube 41 movably arranged on the bracket 23 and an adjusting rod 42 movably penetrated through the mounting tube 41. The moving direction of the adjusting rod 42 is perpendicular to the moving direction of the mounting tube 41, and the end of the adjusting rod 42 is abutted and matched with the vibrating member 22. Specifically, a guide rail and a guide groove are arranged between the mounting tube 41 and the bracket, and the guide rail moves in the guide groove. The guide groove is a dovetail groove, and the guide rail is an inverted trapezoidal slider.

[0035] The vibration rod of this embodiment includes a spiral shape or a bent shape, which can adapt to the structure of different filler layers.

[0036] like Figure 1As shown, the flue gas treatment device also includes a servo motor 51 arranged on the bracket 23, a gear 52 is arranged on the servo motor 51, and a rack that cooperates with the gear 52 is arranged on the mounting tube 41, and the servo motor 51 is drivingly connected to the gear 52. In this way, the servo motor 51 can drive the gear 52 to rotate when working, and the gear 52 can drive the rack to move along the axial direction of the vibration rod, so that the mounting tube 41 drives the adjustment rod 42 to move for position adjustment. In addition, the flue gas treatment device also includes an electric cylinder 53 arranged on the mounting tube 41, and the adjustment rod 42 is the piston rod of the electric cylinder 53. In this way, the piston rod of the electric cylinder 53 can be telescopically moved so that the adjustment rod 42 can adjust the tightness of the vibration rod, thereby facilitating the adjustment of the vibration frequency of the vibration rod.

[0037] like Figure 1 As shown, the flue gas treatment device also includes a frequency detector 32 connected to the vibrating member 22 and a controller arranged on the bracket 23. Each carbon dioxide sensor 31, frequency detector 32, servo motor 51 and electric cylinder 53 are connected to the controller. The controller is preferably a PLC controller. The frequency detector transmits the information of the vibration frequency of the vibrating member to the controller. The multiple carbon dioxide sensors 31 can detect the concentration of carbon dioxide in different areas of the packing layer 12. Each carbon dioxide sensor 31 transmits the information of the detected carbon dioxide concentration to the controller. The controller automatically controls the servo motor 51 and the electric cylinder 53 to work, and then automatically controls the adjustment rod 42 to adjust the vibration frequency of the vibrating member. The PLC controller includes an input / output module, a display interface and a control panel.

[0038] like Figure 1 As shown, the flue gas treatment device also includes a vibration exciter 61 connected to the middle position of the vibrating member 22. The vibration exciter 61 provides auxiliary vibration excitation for the vibration of the vibrating member to ensure that the vibrating member can provide sufficient energy for the uniform distribution of carbonic anhydrase on the packing layer 12, and the vibration exciter 61 is preferably an electromagnetic driver.

[0039] like Figure 1 As shown, the tower body 11 is provided with an avoidance hole for inserting the second end of the vibrating member 22 into the tower body 11. In order to prevent leakage during the carbon dioxide capture process inside the tower body 11, the flue gas treatment device also includes a plug 62. The plug 62 can avoid the vibrating member 22 and seal the avoidance hole. In order to facilitate the normal vibration of the vibrating member 22, the plug 62 can avoid the vibrating member 22.

[0040] like Figure 1 As shown, the flue gas treatment device further includes a phase separator 63 connected to the pump body 21, and the pump body 21 delivers the absorbent (usually liquid) for capturing carbon dioxide discharged from the liquid outlet 16 to the phase separator 63. The phase separator 63 is used to separate the liquid absorbent rich in carbon dioxide from the flue gas.

[0041] The present application also provides a method for adjusting the distribution of carbonic anhydrase, and the distribution of carbonic anhydrase on the packing layer 12 of the above-mentioned flue gas treatment device is adjusted by using the embodiment of the method for adjusting the distribution of carbonic anhydrase. The method for adjusting the distribution of carbonic anhydrase includes the following steps: at a first vibration frequency, the carbonic anhydrase on the packing layer 12 is distributed in the first area and the second area of ​​the packing layer 12 which are arranged laterally; the concentration of carbon dioxide in the first area and the second area different from the first area of ​​the packing layer 12 is detected; when the concentration of carbon dioxide in the first area is less than the concentration of carbon dioxide in the second area, the first vibration frequency is adjusted to a second vibration frequency which is not equal to the first vibration frequency, and a part of the carbonic anhydrase on the first area is distributed to the second area, so that the difference between the concentration of carbon dioxide in the first area and the concentration of carbon dioxide in the second area is within the range of 0 to 10 g / Nm³. Since the above-mentioned flue gas treatment device can solve the problem of energy waste caused by vibration of the pump body during operation in the related technology, the technical solution of adjusting the distribution of carbonic anhydrase on the packing layer 12 of the above-mentioned flue gas treatment device by using the method for adjusting the distribution of carbonic anhydrase can also solve the same technical problem.

[0042] Furthermore, when the pump body 21 generates vibration when working, in order to transfer the energy of the vibration of the pump body 21 to the packing layer 12, before the step of distributing the carbonic anhydrase on the packing layer 12 in the first and second laterally arranged areas of the packing layer 12 at a first vibration frequency, the method for adjusting the distribution of carbonic anhydrase also includes: generating a first vibration frequency when the pump body 21 is working; and transferring the first vibration frequency to the packing layer 12 through the vibrator 22.

[0043] The absorption tower, pump body and vibration element in the present application are used in combination: by connecting the vibration element to the pump body and the absorption tower packing layer, the vibration energy generated by the pump body during operation can be transferred to the packing layer, and this energy can be used to promote the distribution of carbonic anhydrase in the packing layer, thereby improving the capture efficiency of carbon dioxide. This design effectively recovers the kinetic energy of the pump body vibration and avoids energy waste.

[0044] The setting of the protective cover in the present application: the protective cover is arranged on the outside of the vibrating part, which can protect the vibrating part from external mechanical damage and chemical corrosion, ensure the stability and service life of the vibrating part, and at the same time reduce the loss during energy transfer to ensure the effective use of energy.

[0045] The combination of the carbon dioxide sensor and the adjustment part in the present application: multiple carbon dioxide sensors monitor the carbon dioxide concentration in different areas of the packing layer in real time. The vibration frequency can be adjusted according to the difference in carbon dioxide concentration through the adjustment part (in conjunction with the vibration part), so that the distribution of carbonic anhydrase on the packing layer is more uniform, thereby improving the capture efficiency of the entire system.

[0046] The coordination design of the vibration rod and the adjustment part in the present application is as follows: the adjustment part includes a movable mounting tube and an adjustment rod, which can move along the axis direction of the vibration rod, and the adjustment rod is perpendicular to the moving direction of the mounting tube. Such a design allows the vibration frequency to be precisely adjusted to adapt to the characteristics of different packing layers and the distribution requirements of carbonic anhydrase, thereby ensuring that the distribution of carbonic anhydrase matches the carbon dioxide concentration in the flue gas and improving the overall efficiency.

[0047] Control of the servo motor and electric cylinder in the present application: Through the combination of the servo motor and the electric cylinder, the position of the adjustment part and the tightness of the vibration part can be automatically controlled, and then the vibration frequency can be adjusted to achieve dynamic control of the distribution of carbonic anhydrase, thereby improving the system's degree of automation and operating efficiency.

[0048] Introduction of the controller in this application: The controller is connected to the frequency detector and the carbon dioxide sensor, and can automatically control the servo motor and the electric cylinder, automatically adjust the vibration frequency of the vibrating part according to the change of carbon dioxide concentration in different areas of the packing layer, realize intelligent control, and improve the response speed and control accuracy of the system.

[0049] The function of the vibration exciter in this application is: the vibration exciter is connected to the vibrating member to provide additional vibration excitation for the vibrating member, ensuring that the vibration energy is sufficient and uniform. Even when the vibration of the pump body is weakened or unstable, it can ensure the uniform distribution of carbonic anhydrase and improve the stability and reliability of the system.

[0050] The design of the avoidance hole and the plug in this application: the avoidance hole on the tower body allows the second end of the vibrator to be inserted, and the plug blocks the avoidance hole without interfering with the operation of the vibrator, thereby preventing flue gas leakage, ensuring the sealing and safety of the flue gas treatment device, and reducing energy loss.

[0051] The carbonic anhydrase distribution adjustment method in the present application: This method uses the detected changes in carbon dioxide concentration to automatically adjust the vibration frequency, thereby making the distribution of carbonic anhydrase on the packing layer more uniform, reducing the difference in carbon dioxide concentration between regions, improving the carbon dioxide capture efficiency and the utilization rate of the packing layer, and reducing energy waste.

[0052] Utilization and transmission of the vibration frequency of the pump body in this application: The vibration frequency generated by the pump body when working is first transmitted to the packing layer through the vibrating member, providing an energy basis for the subsequent adjustment of the carbonic anhydrase distribution. This step is the key link in energy recovery and reuse in the entire technical solution, ensuring the effective utilization of the vibration energy of the pump body to improve the flue gas treatment efficiency.

[0053] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the devices or elements referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention. The directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0054] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0055] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0056] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations.
