Description

Technical Field

[0001] This utility model relates to the field of carbon dioxide recovery technology, and in particular to a carbon dioxide waste gas recovery device that is beneficial to pollution reduction and carbon reduction. Background Technology

[0002] Most existing waste gas carbon dioxide recovery and treatment devices mix the solution with the waste gas and then evaporate it. After evaporation, the evaporated carbon dioxide is collected through storage equipment. However, during this process, some waste gas residue may remain inside the mixed and evaporated carbon dioxide, making it difficult to completely treat the carbon dioxide in the waste gas.

[0003] Therefore, an existing waste gas carbon dioxide recovery and treatment device, with publication number CN221673852U, evaporates carbon dioxide inside the solution and discharges the carbon dioxide gas from the treatment tank through the outlet pipe. When the device is working, the carbon dioxide gas flows upward and into the interior of the return pipe. By injecting water into the interior of the water inlet pipe and heating the heat conduction ring through the operation of the heating jacket, the water temperature inside the water storage box rises, thereby further heating the carbon dioxide gas and separating the residual substances in the gas. The residual substances in the heated carbon dioxide gas will re-enter the interior of the inlet pipe through the return pipe and flow back into the treatment tank for further treatment, thus fully processing the waste gas.

[0004] However, when the device is treating carbon dioxide in the waste gas, if the carbon dioxide gas after preliminary treatment contains other gaseous impurities, some impurities will be discharged directly from the outlet pipe, and some will be processed again through the return pipe, thus making the function of the return pipe insignificant. Utility Model Content

[0005] The purpose of this invention is to solve the problems existing in the prior art and to propose a carbon dioxide waste gas recovery device that is beneficial to pollution reduction and carbon reduction.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a carbon dioxide waste gas recovery device that is beneficial for pollution reduction and carbon reduction, comprising a treatment box and a return pipe. A partition is fixedly connected inside the treatment box, and the treatment box is divided into upper and lower treatment chambers by the partition. The lower treatment chamber is connected to a selection box through a pipe. A gas outlet pipe is connected to the bottom of the selection box and the side of the selection box near the treatment box. A connecting pipe is connected to the top of the selection box and the side of the selection box near the treatment box. The other end of the connecting pipe is connected to the upper treatment chamber. One end of the return pipe is connected to the top of the selection box and the side of the selection box away from the treatment box, and the other end is connected to the upper treatment chamber. A sealing block is provided inside the selection box to seal one end of the return pipe.

[0007] Preferably, an electric push rod extends through the side of the selection box away from the processing box, and the telescopic end of the electric push rod is fixedly connected to the sealing block.

[0008] Preferably, the bottom of the selection box is fixedly connected to two opposing limiting plates, which are located on both sides of the sealing block and the air outlet pipe, respectively.

[0009] Preferably, the conveying pipe is connected to the partition plate through it, and multiple atomizing nozzles are connected to one side of the conveying pipe. The multiple atomizing nozzles are divided into two groups, and the two groups of atomizing nozzles are located in two processing chambers respectively.

[0010] Preferably, a carbon dioxide purity detector is fixedly connected to the side of the sealing block facing the processing box.

[0011] Preferably, the connecting pipe is equipped with an electric valve.

[0012] Preferably, an electric fan is fixedly installed on one side of each of the two processing chambers.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, by setting up a selection box, a sealing block, an electric push rod, and a carbon dioxide purity detector, the purity of carbon dioxide gas can be determined. When the purity is insufficient, the electric push rod pushes the sealing block to move, promptly blocking the unqualified gas from being discharged from the outlet pipe and guiding it into the return pipe for further processing. This avoids the direct discharge of gas containing impurities, improves the purity of recovered carbon dioxide, and enhances the processing effect of the recovery device.

[0015] 2. In this utility model, by setting up a feeding pipe, an atomizing nozzle and an electric fan, the atomizing nozzle evenly atomizes the liquid medicine in the treatment chamber, increasing the contact area between the liquid medicine and the exhaust gas, while the electric fan agitates the gas in the treatment chamber, accelerating the mixing efficiency of the liquid medicine and the exhaust gas, so that the separation of carbon dioxide and other impurities is more complete.

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] like Figure 1-4 As shown, a carbon dioxide waste gas recovery device that is beneficial for pollution reduction and carbon reduction includes a treatment box 1 and a return pipe 2. A partition 9 is fixedly connected inside the treatment box 1, and the treatment box 1 is divided into upper and lower treatment chambers 15 by the partition 9. The lower treatment chamber 15 is connected to a selection box 4 through a pipe. The bottom of the selection box 4 and the side of the selection box 4 near the treatment box 1 is connected to an outlet pipe 14. The top of the selection box 4 and the side of the selection box 4 near the treatment box 1 is connected to a connecting pipe 3. The other end of the connecting pipe 3 is connected to the upper treatment chamber 15. One end of the return pipe 2 is connected to the top of the selection box 4 and the side of the selection box 4 away from the treatment box 1, and the other end is connected to the upper treatment chamber 15. A sealing block 6 is provided inside the selection box 4 to seal one end of the return pipe 2.

[0024] In this technical solution, among the two processing chambers 15, the lower processing chamber 15 is the main processing chamber. After the gas enters the processing box 1, it first enters the lower processing chamber 15. After processing, the carbon dioxide gas enters the selection box 4 and is discharged through the outlet pipe 14. If the purity of the processed carbon dioxide gas is insufficient, the sealing block 6 moves in the selection box 4, and its bottom blocks the outlet pipe 14 to prevent the gas from being discharged through the outlet pipe 14. After the sealing block 6 moves, one end of the return pipe 2 is exposed, and the carbon dioxide gas with insufficient purity enters the upper processing chamber 15 through the return pipe 2 for further processing to increase the concentration of carbon dioxide.

[0025] Furthermore, by setting the connecting pipe 3, the gas outlet pipe 14 of the sealing block 6 is blocked, and the gas enters the upper processing chamber 15 through the return pipe 2. After the upper processing chamber 15 processes the gas, it returns to the selection box 4 through the connecting pipe 3.

[0026] like Figure 4 As shown, an electric push rod 5 runs through the side of the selection box 4 away from the processing box 1. The telescopic end of the electric push rod 5 is fixedly connected to the sealing block 6. Two opposing limit plates 13 are fixedly connected to the bottom of the selection box 4. The two limit plates 13 are located on both sides of the air outlet pipe 14, and the sealing block 6 is located between the two limit plates 13.

[0027] In this technical solution, an electric push rod 5 is provided to push the sealing block 6 to move, and a limiting plate 13 is provided to guide the sealing block 6 when it moves.

[0028] like Figure 2 As shown, the conveying pipe 8 and the partition plate 9 are connected through each other. Multiple atomizing nozzles 11 are connected to one side of the conveying pipe 8. The multiple atomizing nozzles 11 are divided into two groups, and the two groups of atomizing nozzles 11 are located in two processing chambers 15 respectively.

[0029] In this technical solution, an atomizing nozzle 11 is provided to mix the liquid medicine with the gas.

[0030] like Figure 4 As shown, a carbon dioxide purity detector 12 is fixedly connected to the side of the sealing block 6 facing the processing box 1, and an electric valve 7 is installed on the connecting pipe 3.

[0031] In this technical solution, a carbon dioxide purity detector 12 is set up. When the carbon dioxide purity is insufficient, an alarm is issued, which enables the operator to control the electric push rod 5 to work. An electric valve 7 is set up. When the carbon dioxide purity is normal, it is in the closed state, and when the upper processing chamber 15 needs to discharge gas through the connecting pipe 3, it is in the open state.

[0032] Alternatively, the carbon dioxide purity analyzer 12 can be a μ-GC series miniature gas chromatograph from Membrapor.

[0033] like Figure 3 As shown, an electric fan 10 is fixedly installed on one side of each of the two processing chambers 15.

[0034] In this technical solution, an electric fan 10 is used to agitate the gas inside the treatment box 1, thereby accelerating the mixing efficiency.

[0035] Working principle: After the gas enters the treatment chamber 1, it first enters the lower treatment chamber 15. After treatment, the carbon dioxide gas enters the selection chamber 4 and is discharged through the outlet pipe 14. If the carbon dioxide purity detector 12 detects that the purity of the treated carbon dioxide gas is insufficient, it will sound an alarm, causing the operator to control the electric push rod 5 to extend, which will move the sealing block 6 in the selection chamber 4, blocking the outlet pipe 14 at its bottom to prevent the gas from being discharged through the outlet pipe 14. After the sealing block 6 moves, one end of the return pipe 2 is exposed, and the carbon dioxide gas with insufficient purity enters the upper treatment chamber 15 through the return pipe 2 for further treatment to increase the concentration of carbon dioxide. This continues until the carbon dioxide purity detector 12 detects that the gas purity in the lower treatment chamber 15 is sufficient. The electric push rod 5 retracts, causing the sealing block 6 to reset, re-blocking the return pipe 2 and exposing the outlet pipe 14. At this time, the electric valve 7 opens, and the carbon dioxide gas in both the upper and lower treatment chambers 15 is discharged through the outlet pipe 14.

[0036] The wiring diagrams for the electric push rod 5, electric valve 7, electric fan 10, and carbon dioxide purity detector 12 in this utility model are common knowledge in the field. Their working principles are known technologies. The appropriate model is selected according to actual use. Therefore, the control methods and wiring layouts of the electric push rod 5, electric valve 7, electric fan 10, and carbon dioxide purity detector 12 will not be explained in detail.

[0037] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
