Description

Technical Field

[0001] This utility model relates to the field of burner technology, and in particular to a sulfur recovery reactor burner. Background Technology

[0002] Existing sulfur recovery reactor burners generally employ an axial arrangement, meaning the burner axis is coaxial with the reactor axis. This structure has the following drawbacks:

[0003] 1. Uneven mixing: The acid gas has low diffusion mixing efficiency with air / oxygen in the furnace, which easily leads to incomplete reaction;

[0004] 2. Concentrated flame: The high-temperature zone is concentrated in the center of the furnace body, and the furnace lining is prone to local overheating and damage;

[0005] 3. Turbulent flow field: Axial jets are prone to forming backflow zones, resulting in uneven material residence time, local dead zones, and uneven heating, which increases the risk of side reactions.

[0006] Traditional sulfur recovery reactor burners all adopt an axial arrangement scheme and lack optimized design for tangential swirl enhancement. Utility Model Content

[0007] To address the aforementioned technical problems, this invention provides a sulfur recovery reactor burner that can effectively improve the reaction rate and recovery efficiency while reducing pollutant emissions.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0009] This utility model provides a sulfur recovery reactor burner, including a reactor body and a burner. The burner is equipped with a process gas injection gun and a fuel gas injection gun. The central axis of the burner is perpendicular to the central axis of the reactor body, and the burner is installed in the tangential direction on the periphery of the reactor body. The angle between the central axis of the burner and the central axis of the reactor body is 90°.

[0010] Furthermore, a vortex generator is installed inside the burner's air box, and the ratio of the projected overlap area between adjacent blades of the vortex generator is 1.5-1.6.

[0011] Furthermore, the blade adjustment angle of the vortex generator is ±15°.

[0012] Furthermore, the process gas spray gun is equipped with flow stabilizing blades, and the flow stabilizing blades are tilted at an angle of 45°.

[0013] Furthermore, the spray diffusion angle of the fuel gas nozzle is 60°.

[0014] Furthermore, the reactor body is provided with a flange interface on its periphery, and the flange interface is set along the tangential direction of the periphery of the reactor body; the burner is connected to the flange interface.

[0015] The above technical solution has the following advantages or beneficial effects: The sulfur recovery reactor burner provided by this utility model includes a reactor body and a burner. The burner is equipped with a process gas injection gun and a fuel gas injection gun. The central axis of the burner is perpendicular to the central axis of the reactor body, and the burner is installed tangentially to the periphery of the reactor body. The angle between the central axis of the burner and the central axis of the reactor body is 90°. The sulfur recovery reactor burner provided by this utility model can effectively improve the reaction rate and recovery efficiency, and reduce pollutant emissions. Attached Figure Description

[0021] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0022] Example 1:

[0023] like Figure 1-3 As shown:

[0024] The present invention provides a sulfur recovery reactor burner, comprising a reactor body 1 and a burner 2. The burner 2 is provided with a process gas spray gun 21 and a fuel gas spray gun 3. The central axis of the burner 2 is perpendicular to the central axis of the reactor body 1, and the burner 2 is installed in the tangential direction around the reactor body 1. The angle between the central axis of the burner 2 and the central axis of the reactor body 1 is 90°.

[0025] Because the existing reactor body 1 and burner 2 are coaxially connected in series, the diffusion and mixing efficiency of acid gas and oxygen is low. This invention addresses this by vertically connecting the reactor body 1 and burner 2, with the burner 2 positioned on the side wall of the reactor body 1. The flame diffuses tangentially along the furnace wall, avoiding localized high temperatures and dead zones, thus protecting the furnace lining. The swirling flow field propels the material forward in a spiral, resulting in a more uniform residence time distribution and reduced byproducts. This structure creates a stable and intense swirling flow within the furnace, improving temperature uniformity. Combustion is strong, the flame is short, and operation is stable. Using this structure, the sulfur conversion rate increases by approximately 1.0%-2.5%, the residual content of pollutants such as nitrogen oxides and nitric oxide is lower, and the furnace lining lifespan can be extended by 20%.
