[0002] In various smelting processes, excessive sulfur-containing tail gas is often generated. Sulfur-containing tail gas can be treated primarily using wet or dry methods. Because dry treatment does not produce wastewater, it is more environmentally friendly and has become the preferred choice for an increasing number of manufacturers. Currently, dry desulfurization processes require the combined use of multiple reagents to achieve desulfurization. Existing technologies require a material tower for each reagent, resulting in long and complex pipeline routes between towers, a large footprint, increased instability in the sulfur-containing tail gas treatment process, and significantly increased costs.

[0023] The embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0024] Example

[0025] Please refer to Figures 1-3This embodiment provides a material tower for tail gas desulfurization, including a tower body 10. The tower body 10 is a cylindrical structure made of stainless steel plate and coated with high temperature resistant and anti-corrosion coating inside and out. The entire tower body 10 is insulated with aluminum silicate plate. The tower body 10 has an air inlet 11 and an air outlet 12. The air inlet 11 is located below the air outlet 12. The air inlet 11 is located at the bottom of the tower body 10, and the air outlet 12 is located at the top of the tower body 10. At least two partitions 20 are arranged vertically inside the tower body 10. The partitions 20 have multiple ventilation mesh holes 21. In this embodiment, two partitions 20 are preferably used, with a spacing of 2-3 meters. The partitions 20 are made of stainless steel plate with a thickness of 10 mm. The ventilation mesh holes 21 are used for the passage of sulfur-containing tail gas, and the aperture of the ventilation mesh holes 21 is 1 mm. The partitions 20 divide the interior of the tower body 10 into at least a conversion chamber 13 and an absorption chamber 14. The conversion chamber 13 is located below the absorption chamber 14. The conversion chamber 13 is located between the two partitions 20, and the absorption chamber 14 is located between the top partition 20 and the air outlet 12.

[0026] In the specific implementation process, the top baffle 20 is used to place desulfurizing agents and other reagents, and the bottom baffle 20 is used to place conversion agents and other reagents. Sulfur-containing tail gas is input into the tower 10 through the air inlet 11 at the bottom of the tower 10. The sulfur-containing tail gas first enters the conversion chamber 13 through multiple ventilation meshes 21 of the bottom baffle 20, where it comes into contact with the conversion agent. After conversion by the conversion agent, the sulfur-containing tail gas then enters the absorption chamber 14 through multiple ventilation meshes 21 of the top baffle 20, where it comes into contact with the desulfurizing agent. After desulfurization by the desulfurizing agent, the desulfurized tail gas is discharged from the tower 10 through the air outlet 12, completing the dry desulfurization process of the sulfur-containing tail gas. Therefore, this application, by setting up two baffles, allows for the placement of two desulfurization materials in one material tower, greatly reducing the number of desulfurization towers, reducing pipeline usage and floor space, lowering costs, and providing a reliable and efficient solution for the dry desulfurization of sulfur-containing tail gas.

[0027] like Figures 1-3 As shown, in some embodiments, the side wall of the tower body 10 has multiple manholes 15, and both the conversion chamber 13 and the absorption chamber 14 are connected to at least one manhole 15. A sealing cap can be installed at each manhole 15 for sealing. By providing manholes 15, this invention allows operators to add reagents to the conversion chamber 13 and absorption chamber 14 through the manholes 15, and also to clean the reagents within the conversion chamber 13 and absorption chamber 14 through the manholes 15, making operation convenient.

[0028] like Figures 1-3As shown, in some embodiments, the partition 20 is provided with a discharge hole, and a discharge valve 22 is provided at the discharge hole of the partition 20. The discharge valve 22 can be a manual discharge valve or an automatic discharge valve. The top of the tower body 10 has a feed inlet 16, and a sealing cap can be provided at the feed inlet 16 for sealing. The bottom of the tower body 10 has a discharge port 17, and a sealing cap can be provided at the discharge port 17 for sealing.

[0029] This invention facilitates the addition and cleaning of chemicals by providing a discharge hole, a feed inlet 16, and a discharge port 17. When adding chemicals, they can be added into the tower body 10 through the feed inlet 16. First, the chemicals in the lower conversion chamber 13 are filled. At this time, the discharge valve 22 of the bottom partition 20 is closed, and the discharge valve 22 of the top partition 20 is opened. The chemicals are added into the tower body 10 through the feed inlet 16. The chemicals fall into the top of the bottom partition 20 through the discharge valve 22 of the top partition 20. At this time, the chemicals on the top of the bottom partition 20 can be spread flat on the bottom partition 20 through the manhole 15 at the bottom. After filling the chemicals in the lower conversion chamber 13, the discharge valve 22 of the top partition 20 is closed, and the chemicals can continue to be added into the top partition 20 through the feed inlet 16.

[0030] When cleaning the chemicals, first clean the chemicals on the top of the bottom partition 20. This involves opening the discharge valve 22 of the bottom partition 20, and having the worker push the chemicals on the bottom partition 20 to the discharge valve 22 through the manhole 15 at the bottom. The chemicals will then fall through the discharge valve 22 into the discharge port 17 and out. Next, clean the chemicals on the top partition 20. Again, open the discharge valve 22 of the top partition 20, and have the worker push the chemicals on the top partition 20 to the discharge valve 22 through the manhole 15 at the top. The chemicals will then fall through the discharge valve 22 for cleaning.

[0031] like Figures 1-3 As shown, in some embodiments, the discharge holes of each partition 20 are coaxially arranged with the inlet 16. In this way, the medicine falling from the inlet 16 can fall directly into the discharge valve 22 at the discharge hole position, making it convenient to add medicine to the bottom partition 20.

[0032] like Figures 1-3 As shown, in some embodiments, the top of the tower body 10 has multiple instrument interfaces 18. This invention, by providing multiple instrument interfaces 18, facilitates the connection of instruments such as thermometers and pressure gauges for monitoring.

[0033] like Figures 1-3 As shown, in some embodiments, a support 30 is provided around the tower body 10. By providing the support 30, this utility model facilitates the installation and support of the tower body 10. The support 30 can be made of cement, and the tower body 10 can be fixed to the support 30 using expansion bolts.

[0034] Furthermore, unless otherwise explicitly specified or limited, the terms "installation" and "connection" in this application embodiment should be interpreted broadly. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. The terms "upper," "lower," "left," "right," "inner," "outer," and "side," etc., are merely for reference to the direction in the accompanying drawings or the usual placement of the product during use. They are only for clearly describing this application and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. They should not be construed as limitations on this application. The terms "first," "second," etc., are only used for distinguishing descriptions and should not be construed as indicating or implying relative importance; "multiple" refers to at least two. In this application embodiment, the limitations on relative positional relationships such as parallel, perpendicular, and aligned are all relative to the current technological level and are not absolutely strict limitations. Slight deviations are allowed; approximations of parallel, perpendicular, and aligned are all acceptable. For example, "A and B are parallel" means that A and B are parallel or approximately parallel, and the angle between A and B can be between 0 degrees and 10 degrees.
