Description

Technical Field

[0001] The present application relates to the technical field of airflow distribution equipment, and in particular to a flue denitrification ozone distribution device. Background Art

[0002] During the metal smelting process, a large amount of waste gas is generated, such as sulfur dioxide, nitrogen monoxide and other waste gases. These waste gases contain a large amount of harmful gases that need to be removed before they are discharged. In the process of denitrification, ozone is used for denitrification. During the treatment process, the prepared ozone gas is introduced into the flue gas pipe so that it can fully react with the nitric gas to produce nitrate. In actual use, ozone is usually introduced through a pipe. However, the ozone introduced in this way is unevenly distributed in the pipe, resulting in insufficient reaction. Moreover, the flue gas is flowing, which will drive the ozone forward, which is not conducive to the reaction. Utility Model Content

[0003] In order to solve or partially solve the problems existing in the related art, the present application provides a flue denitrification ozone distribution device, which can evenly distribute ozone to ensure sufficient denitrification reaction.

[0004] The present application discloses a flue denitrification ozone distribution device, comprising:

[0005] The main pipeline is configured as a double-layer pipe, including an outer pipe and an inner pipe. The interlayer between the outer pipe and the inner pipe constitutes an air distribution layer. An air inlet pipe is formed on the outer pipe to connect to the air distribution layer. Flanges are constructed on both sides of the main pipeline; and

[0006] The air distribution pipe is set to three layers, namely the central air distribution pipe, the outer air distribution pipe, and the middle air distribution pipe;

[0007] Among them, the end faces of the central air distribution pipe, outer air distribution pipe and middle air distribution pipe of the air distribution pipe are in the same plane; the central air distribution pipe, outer air distribution pipe and middle air distribution pipe are arranged on the inner side of the inner pipe and connected to the air distribution layer of the main pipe.

[0008] Optionally, the central air distribution pipe is set as one pipe; more than 6 middle air distribution pipes are set around the central air distribution pipe; and more than 6 outer air distribution pipes are set around the middle air distribution pipe.

[0009] Optionally, at least three layers of spiral sheets are spirally arranged on the inner wall of the air distribution pipe on one side of the air outlet to form three air outlet holes.

[0010] Optionally, at least five layers of spiral sheets are spirally arranged on the inner wall of the air distribution pipe on one side of the air outlet to form five air outlet holes.

[0011] Optionally, a wire mesh is provided on one side of the air outlet of the air distribution pipe.

[0012] Optionally, the diameter of the central air distribution pipe is set to 6 times the diameter of the middle air distribution pipe and 2 times the diameter of the outer air distribution pipe.

[0013] The technical solution provided by this application may have the following beneficial effects:

[0014] This device installs a three-layered air distribution pipe array within a single plane within the main pipeline's inner tube. Ozone is then introduced into the inner tube through a network of interconnected air distribution layers. During operation, the air distribution pipes are aligned with the incoming flue gas. As the flue gas passes through, it collides with the flue gas through the three layers of air distribution pipes, encompassing the center, middle, and outer layers. This collision with the flue gas allows the ozone to react with the flue gas at three levels, effectively removing nitrate. Ozone is introduced evenly, ensuring a thorough denitrification reaction.

[0030] In response to the above problems, an embodiment of the present application provides a flue denitrification ozone distribution device. The technical solution of the embodiment of the present application is described in detail below with reference to the accompanying drawings.

[0031] like Figure 1 A flue denitrification ozone distribution device shown includes:

[0032] The main pipeline 1 is provided as a double-layer pipeline, including an outer pipe 11 and an inner pipe 12, and a gas distribution layer 13 is formed between the outer pipe 11 and the inner pipe 12. The outer pipe 11 is provided with an air inlet pipe 14 connected to the gas distribution layer 13, and flanges 3 are arranged on both sides of the main pipeline 1. In this application, the main pipeline 1 is connected to the flue gas pipeline during use, and then the air inlet pipe 14 is connected to the ozone pipeline. In this way, ozone can be filled into the gas distribution layer 13, and it is recommended to use ozone with air pressure during use.

[0033] The application also includes a gas distribution pipe 2, which is provided as a three-layer pipe, including a central gas distribution pipe 21, an outer gas distribution pipe 22, and a middle gas distribution pipe 23. The pipe end faces of the central gas distribution pipe 21, the outer gas distribution pipe 22, and the middle gas distribution pipe 23 are in the same plane, and the central gas distribution pipe 21, the outer gas distribution pipe 22, and the middle gas distribution pipe 23 are arranged on the inner side of the inner pipe 12 and connected to the gas distribution layer 13 of the main pipeline 1.

[0034] In this way, the application arranges the three-layer gas distribution pipe array in one plane of the inner pipe 12 of the main pipeline 1, and then fills ozone into the inner pipe 12 through the same gas distribution layer. During use, the gas distribution pipe 2 is arranged to face the direction of the flue gas, and the flue gas passes through the three-layer gas distribution pipe to collide with the flue gas. The three-layer gas distribution pipe includes a central layer, a middle layer, and an outer layer. The ozone and the flue gas react on the three layers to remove nitrogen through collision with the flue gas. The ozone is evenly distributed, and the reaction is sufficient.

[0035] In one embodiment, as shown in Figure 2 The central gas distribution pipe 21 is provided as one pipe, the middle gas distribution pipe 23 is provided as more than 6 pipes surrounding the central gas distribution pipe 21, and specifically 12 pipes, and the outer gas distribution pipe 22 is provided as more than 6 pipes surrounding the middle gas distribution pipe 23, and specifically 12 pipes. In this way, the overall gas distribution pipe 2 occupies a relatively reasonable pipe surface of the main pipeline 1, and the ozone gas is relatively evenly distributed.

[0036] As an option, the diameter of the central gas distribution pipe 21 is 6 times the diameter of the middle gas distribution pipe 23, and 2 times the diameter of the outer gas distribution pipe 22. In this way, the gas distribution pipes on the central and outer sides have a larger outlet, while the middle layer between them is relatively small, facilitating collision with the flue gas and thus sufficient reaction.

[0037] In one embodiment, in order to avoid the gas blown out by the gas distribution pipe 2 from being concentrated, as shown in Figure 3As shown, the inner wall of the air distribution pipe 2 on the outlet side is spirally provided with at least three layers of spiral blades to form three spiral air outlet holes, or at least five layers of spiral blades to form five spiral air outlet holes. Furthermore, a wire mesh 5 is provided on the outlet side of the air distribution pipe 2. This allows the airflow to be blown out by the wind pressure and easily form a spiral trumpet shape. This allows the ozone emitted from the three air distribution pipes 2 on the same plane to form a collision surface and react with the flue gas. This results in a more even distribution of ozone within the cross-sectional area, and a more complete denitrification reaction.

[0038] Finally, it should be noted that, in this document, relationships such as first and second, etc., are used solely to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms include, comprise, or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
