Description

Technical Field

[0001] The present application relates to the technical field of carbon dioxide mineralization and maintenance, and in particular to an airflow disturbance device. Background Art

[0002] The implementation of carbon dioxide mineralization curing concrete technology relies on a carbon dioxide mineralization curing kettle. In the existing carbon dioxide mineralization curing kettle technology, a gas pipeline is usually provided inside the cavity of the curing kettle, and the gas pipeline is connected to an external gas supply pipeline for transporting carbon dioxide gas from the outside to the cavity of the curing kettle. As the carbon dioxide gas is input, the carbon dioxide diffuses in the curing kettle and undergoes a mineralization reaction with the concrete products in the kettle, thereby achieving the curing and performance improvement of the concrete. The existing gas pipeline directly transports the carbon dioxide gas into the cavity of the curing kettle. This method causes the carbon dioxide concentration at the outlet to increase instantly when the carbon dioxide gas is discharged from the outlet of the gas pipeline, resulting in extremely uneven distribution of the carbon dioxide gas in the curing kettle. This uneven distribution has a serious impact on the mineralization reaction of the products in the kettle, resulting in large differences in the mineralization reaction rate and carbon fixation rate of the products in the curing kettle. Summary of the Invention

[0003] In view of this, the present application proposes an air flow disturbance device suitable for installation in the cavity of a curing kettle, comprising: a gas transmission pipeline and two or more flow disturbance components;

[0004] The gas pipeline is fixedly mounted on the inner side wall of the curing kettle, and is provided with a cavity with two ends opened. One end of the gas pipeline is adapted to be connected to an external gas supply pipeline. Two or more ventilation holes are provided on the outer side wall of the gas pipeline, and the ventilation holes are evenly spaced along the length of the gas pipeline. Two or more flow-turbulating components are provided at the ventilation holes of the gas pipeline, and the two or more flow-turbulating components correspond one-to-one to the two or more ventilation holes.

[0005] Each of the two or more spoiler assemblies includes: an air jet pipe and a spoiler. The air jet pipe is provided with a cavity with openings at both ends. One end of the air jet pipe is fixedly arranged on the outer wall of the gas transmission pipe, and the cavity of the air jet pipe is connected to the cavity of the gas transmission pipe. The spoiler is fixedly installed in the cavity of the air jet pipe and is suitable for forming a uniform airflow when the gas passes through the spoiler.

[0006] In one possible implementation, the spoiler includes a hub and two or more guide blades; the two or more guide blades are equidistantly arranged along the circumference of the hub, and the hub is fixed in the cavity of the jet duct through the guide blades.

[0007] In one possible implementation, there are ten wind guide blades.

[0008] In a possible implementation manner, the main body of each wind guide blade is a curved sheet-like structure.

[0009] In a possible implementation, the main body of the jet pipe is a tubular structure, and the length direction of the jet pipe is perpendicular to the length direction of the gas transmission pipe.

[0010] In a possible implementation manner, the length directions of the two or more air-jet ducts are parallel to each other.

[0011] In one possible implementation, a flange is provided at one end of the gas transmission pipeline; the gas transmission pipeline is connected to an external gas supply pipeline via the flange.

[0012] Beneficial effects of this application

[0013] By setting up the spoiler component, the spoiler component can break the laminar flow state of the carbon dioxide gas, thereby promoting a more uniform distribution of the carbon dioxide gas in the curing kettle, ensuring that the concrete products can obtain a uniform gas environment during the curing process, and improving the curing quality of the concrete products.

[0014] By arranging the spoiler in the cavity of the jet pipe, the spoiler guides the carbon dioxide gas in the jet pipe to form a rotating airflow and then transports it to the curing kettle. This method helps to evenly distribute the carbon dioxide gas in the cavity of the curing kettle. Compared with the direct injection or natural flow method in the prior art, the rotating airflow can more effectively reduce the gas concentration gradient, so that the carbon dioxide gas can be more evenly covered in every corner of the curing kettle, thereby improving the uniformity of the carbon dioxide gas in the curing kettle and making the reaction between the concrete products in the kettle and the carbon dioxide gas more complete.

[0027] This application proposes an air flow disturbance device suitable for installation in the cavity of a curing kettle 300, such as Figures 1 to 5As shown, it includes: a gas pipeline 100 and two or more spoiler components; the gas pipeline 100 is fixedly arranged on the inner wall of the curing kettle 300, the gas pipeline 100 is provided with a cavity with two ends opened, one end of the gas pipeline 100 is suitable for communicating with the external gas supply pipeline, and the outer wall of the gas pipeline 100 is provided with two or more ventilation holes 110, and the ventilation holes 110 are equidistantly distributed along the body length direction of the gas pipeline 100, and the two or more spoiler components are arranged at the ventilation holes 110 of the gas pipeline 100, and The two or more spoiler assemblies correspond one-to-one to the two or more ventilation holes; the two or more spoiler assemblies each include: an air jet duct 210 and a spoiler 220, the air jet duct 210 is provided with a cavity with openings at both ends, one end of the air jet duct 210 is fixedly arranged on the outer wall of the gas transmission pipeline 100, and the cavity of the air jet duct 210 is connected to the cavity of the gas transmission pipeline 100, and the spoiler 220 is fixedly installed in the cavity of the air jet duct 210, and is suitable for forming a uniform airflow when the gas passes through the spoiler 220.

[0028] It should be noted here that the gas pipeline 100 is fixedly arranged on the inner wall of the curing kettle 300 to ensure that the gas pipeline 100 remains stable in the curing kettle 300 and will not be displaced or deformed due to the flow of gas or other factors, thereby ensuring the stable delivery of gas. One end of the gas pipeline 100 is connected to the external gas supply pipeline, which can ensure that carbon dioxide gas enters the gas pipeline 100 stably and continuously from the outside and is then delivered to the cavity of the curing kettle 300. The ventilation hole 110 is suitable for delivering the carbon dioxide gas in the gas pipeline 100 to the cavity of the curing kettle 300. When the gas enters the curing kettle 300 from the gas pipeline 100, as shown in FIG. Figure 4 As shown, the design of equidistant distribution of the ventilation holes 110 along the length of the gas transmission pipeline 100 can ensure that each area in the curing kettle 300 can obtain the same concentration of gas, thereby improving the consistency of the curing effect. By providing a spoiler component, the spoiler component can break the laminar flow state of the carbon dioxide gas, thereby promoting a more uniform distribution of the carbon dioxide gas in the curing kettle 300, ensuring that the concrete products can obtain a uniform gas environment during the curing process, thereby improving the curing quality of the concrete products.

[0029] like Figure 1 、 Figure 3As shown, the design of the jet pipe 210 with openings at both ends allows carbon dioxide gas to flow smoothly from the gas pipeline 100 into the jet pipe 210, and transport the carbon dioxide gas to the cavity of the curing kettle 300 through its cavity with openings at both ends. The jet pipe 210 ensures that the carbon dioxide gas can be evenly distributed at the required position. The cavity of the jet pipe 210 is connected to the cavity of the gas pipeline 100. The carbon dioxide gas can transition from the gas pipeline 100 to the jet pipe 210 without the need for additional pumping or pressure equipment. This ensures the continuity and stability of the carbon dioxide gas flow and avoids the accumulation or leakage of carbon dioxide gas at the connection between the gas pipeline 100 and the jet pipe 210.

[0030] By arranging the spoiler 220 in the cavity of the air jet duct 210, the spoiler 220 guides the carbon dioxide gas in the air jet duct 210 to form a rotating airflow, which is then transported into the curing kettle 300. This method helps to evenly distribute the carbon dioxide gas in the cavity of the curing kettle 300. Compared with the direct injection or natural flow methods in the prior art, the rotating airflow can more effectively reduce the gas concentration gradient, allowing the carbon dioxide gas to more evenly cover every corner of the curing kettle 300, thereby improving the uniformity of the carbon dioxide gas in the curing kettle 300 and ensuring a more complete reaction between the concrete products in the kettle and the carbon dioxide gas.

[0031] Furthermore, a preset distance is set between every two adjacent ventilation holes 110 , and the preset distance has a value range of 0.5 m to 3 m.

[0032] In one possible implementation, Figure 1 、 Figure 3 As shown, the main body of the jet pipe 210 is a tubular structure, and the length direction of the jet pipe 210 is perpendicular to the length direction of the gas pipeline 100. It should be noted that the tubular structure of the jet pipe 210 can provide a larger flow area, thereby allowing carbon dioxide gas to pass through at a higher speed, improving transmission efficiency. The inner diameter of the jet pipe 210 matches the diameter of the vent hole. The jet pipe 210 is fixedly installed at the vent hole 110 of the gas pipeline 100 by welding. The welding connection method ensures a firm and reliable connection between the jet pipe 210 and the gas pipeline 100, preventing leakage during carbon dioxide gas transmission and ensuring the stability of carbon dioxide gas transmission.

[0033] In one possible implementation, the length directions of two or more jet pipes 210 are parallel to each other. The parallel jet pipes 210 can generate airflow disturbances in a specific direction, guiding the carbon dioxide gas to flow along a preset path, ensuring that different positions in the cavity of the curing kettle 300 can receive the carbon dioxide gas more evenly, thereby improving the curing quality.

[0034] In one possible implementation, Figure 2 、 Figure 3 As shown, the spoiler 220 includes a hub 221 and two or more guide blades 222 ; the two or more guide blades 222 are equidistantly arranged along the circumference of the hub 221 ; the hub 221 is fixedly arranged in the cavity of the jet duct 210 through the guide blades 222 .

[0035] It should be noted here that one end of the guide blade 222 is fixedly connected to the hub 221 by welding, and the end of the guide blade 222 away from the hub 221 is fixedly connected to the inner wall of the jet duct 210 by welding. The guide blade 222 is connected to the hub 221 and the inner wall of the jet duct 210 by welding to form a stable overall structure, ensuring that the spoiler 220 will not loosen or shift, and ensuring its normal function. The fixed position of the guide blade 222 in the jet duct 210 enables it to effectively guide the airflow. When the carbon dioxide gas passes through the jet duct 210, the guide blade 222 can change the direction and speed of the airflow, so that it guides the carbon dioxide gas to flow along a specific path to form a rotating airflow, thereby achieving effective disturbance and uniform distribution of the carbon dioxide gas in the curing kettle 300, improving the mineralization reaction rate and carbon fixation rate of the product in the curing kettle 300, thereby improving the performance and quality of the entire curing process.

[0036] Further, such as Figure 2 As shown, two or more guide blades 222 are equidistantly arranged along the circumference of the hub 221. The two or more guide blades 222 can more effectively change the direction and speed of the airflow. The guide blades 222 equidistantly arranged along the circumference of the hub 221 can simultaneously guide the carbon dioxide gas from different angles, so that the carbon dioxide gas flows more smoothly along a specific path, thereby forming a stable rotating airflow. The two or more guide blades 222 work together to guide the carbon dioxide gas to form a rotating airflow, so that the concrete products in the kettle are fully in contact with the carbon dioxide gas, thereby improving the uniformity of the mineralization reaction of the concrete products and the carbon fixation rate.

[0037] Preferably, there are ten air guide blades 222 .

[0038] In one possible implementation, Figure 2 As shown, the main body of each guide vane 222 is a curved sheet-like structure. It should be noted that the curved sheet-like structure of the guide vanes 222 can guide the carbon dioxide gas along a specific path, reducing airflow turbulence and the formation of vortices. This helps optimize airflow distribution and improve the efficiency and stability of gas flow.

[0039] Furthermore, the guide blade 222 is provided with a preset bending angle, wherein the preset bending angle refers to the degree of bending of the guide blade 222 along its length, that is, the angle formed by the guide blade 222 and the rotating plane from the root of the guide blade 222 to the tip of the guide blade 222. By setting the preset bending angle, the guide blade 222 with the preset bending angle can more effectively guide the flow of carbon dioxide gas, so that it forms a more uniform rotating airflow in the jet duct 210, thereby enhancing the turbulence effect.

[0040] Preferably, the preset bending angle ranges from 10° to 40°.

[0041] In a possible implementation, a flange 120 is provided at one end of the gas pipeline 100, and the gas pipeline 100 is connected to an external gas pipeline via the flange 120. Figure 1 As shown, a flange 120 is provided on the gas pipeline 100 ; the flange 120 is fixedly mounted on one end of the gas pipeline 100 , and the gas pipeline 100 is connected to an external gas supply pipeline via the flange 120 . It should be noted here that the flange 120 has a hollow structure, and the aperture size of the flange 120 matches the outer diameter of the gas pipeline 100. The gas pipeline 100 is fixedly connected to the flange 120 by welding. The welding connection method makes the gas pipeline 100 and the flange 120 more stable, and the external gas supply pipeline is fixedly provided with a fixed flange 120. A plurality of mounting holes 121 are dispersedly provided on the end face of the flange 120. Correspondingly, a plurality of fixing holes are dispersedly provided on the end face of the fixed flange 120, and the mounting holes 121 are coaxially arranged with the fixing holes. The bolts pass through the mounting holes 121 on the flange 120 and are connected with the fixing holes on the fixed flange 120, thereby connecting the external gas supply pipeline with the gas pipeline 100. The gas pipeline 100 is connected to the external gas supply pipeline through the flange 120, making the connection between the external gas supply pipeline and the gas pipeline 100 simple and quick. This connection method not only reduces the installation time, but also reduces the installation difficulty.

[0042] The gas disturbance device of the present application can be installed in the cavity of the curing kettle 300 in multiple ways according to actual conditions, such as Figure 5 As shown, at least two gas pipelines 100 are provided; the at least two gas pipelines 100 are arranged parallel to each other. It should be noted that the two or more parallel gas pipelines 100 simultaneously transport carbon dioxide gas, ensuring uniform distribution of the carbon dioxide gas within the cavity of the curing kettle 300. This improves gas transport efficiency and ensures uniformity and consistency in the reaction process between the concrete product and the carbon dioxide gas within the curing kettle 300.
