Abstract
Description
Technical Field
[0001] This utility model belongs to the field of absorption towers and relates to an alloy tray for a sulfur absorption tower. Background Technology
[0002] In the field of flue gas desulfurization, sulfur absorption towers are core equipment for purifying industrial waste gas and reducing air pollution, and their performance and efficiency are crucial. However, the traditional tray design of sulfur absorption towers has revealed some key problems in practical applications. Although these trays can achieve contact and reaction between flue gas and slurry to a certain extent, problems such as poor slurry flow and severe deposit and scaling are common, posing a serious challenge to desulfurization efficiency and stable operation of the equipment.
[0003] Specifically, traditional pallet designs often fail to adequately consider the flow characteristics of the slurry on the pallet surface, resulting in extremely uneven slurry distribution. This uneven distribution easily leads to accumulation and eddies in localized areas, severely hindering effective contact between the slurry and flue gas, thereby reducing desulfurization efficiency. More seriously, this accumulation and eddy phenomenon also exacerbates slurry deposition and scaling, not only shortening the pallet's lifespan but also significantly increasing equipment maintenance costs and operational complexity, placing a considerable burden on the company's production and operations.

[0023] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0024] The following is in conjunction with the appendix Figure 1 To be continued Figure 3 The present invention will be described in detail with reference to specific embodiments:
[0025] A sulfur absorption tower alloy tray, referring to Figure 1, includes a base plate 1, side plates 2, auxiliary plates 3, reinforcing ribs 4, flow guide holes 5 and flow guide grooves 6. The two ends of the base plate 1 are vertically fixed to the side plates 2, and the top of the side plates 2 is horizontally fixed to the auxiliary plates 3. A number of flow guide holes 5 are evenly distributed on the surface of the base plate 1.
[0026] The pallet adopts a flat plate design, which not only significantly reduces the "flooding" phenomenon, but also simplifies the pallet's production and processing process and reduces the difficulty of construction and installation. Overall, the pallet of this utility model has a simple and stable structure, economical manufacturing cost, and strong practicality, making it a high-efficiency component in the sulfur absorption tower system.
[0027] refer to Figure 2 The bottom plate 1 has several guide grooves 6 evenly distributed on its surface. The guide grooves 6 are arranged in a crisscross pattern. The flow rate of the slurry on the surface of the bottom plate 1 is increased by the crisscrossing and interconnected guide grooves 6, which alleviates the problem of solid matter in the reaction liquid depositing and scaling on the tray.
[0028] The upper surface of the base plate 1 is provided with multiple equally spaced parallel reinforcing ribs 4. The two ends of the reinforcing ribs 4 are fixed to the surface of the side plates 2 to form a reinforced support structure. The top of the reinforcing ribs 4 is fixed with stiffening ribs 7. The reinforcing ribs 4 effectively increase the stability between the side plates 2, and the stiffening ribs 7 further increase the stability of the overall structure.
[0029] refer to Figure 3 The guide hole 5 includes an arc-shaped hole 51 and a guide plate 52. One side of the arc-shaped hole 51 is semi-circular, and the guide plate 52 is semi-circular and curves upward to form an angle with the base plate 1. The bottom edge of the guide plate 52 is fixed to the other side of the arc-shaped hole 51.
[0030] The length of the bottom edge of the guide vane 52 is equal to the length of the side edge that connects to the arc-shaped hole 51.
[0031] The arc-shaped orifice 51 and the planar projection of the guide vane 52 form an orifice shape with a semi-circular arc band of width. The semi-circular arc band of the orifice shape helps to reduce the resistance to fluid flow, allowing the fluid to pass through the tray more smoothly, thereby improving the overall efficiency of the sulfur absorption tower system.
[0032] The cross-section of the arc-shaped hole 51 along its length is a trapezoid that is narrower at the top and wider at the bottom, which is beneficial for the slurry to pass through the arc-shaped hole 51.
[0033] The angle between the guide vane 52 and the base plate 1 is 45~60°. The angle between the guide vane 52 and the base plate 1 can be adjusted according to the design requirements of different desulfurization systems. The upward direction of the guide vane 52 is generally along the flue gas direction.
[0034] The guide hole 5 guides the flue gas, preventing it from accumulating and creating a "lifting" effect. Even when a large amount of slurry flows through the tray, it can still maintain a good slurry descent effect. At the same time, it can achieve a good uniform distribution effect after the flue gas flows through the tray.
[0035] The opening ratio of the bottom plate 1 is 40-50%, which is the ratio of the area of the several arc-shaped holes 51 to the area of the bottom plate 1. This opening ratio ensures that there is more space on the bottom plate 1 for the passage and distribution of fluids. This helps to ensure that fluids such as slurry can flow evenly and efficiently through the tray, reducing the possibility of dead corners and fluid accumulation, thereby improving the overall treatment efficiency of the sulfur absorption tower.
[0036] The size, number, and angle of the openings in the tray can be adjusted according to the design requirements of different desulfurization systems, which can meet the layout requirements of different types of desulfurization towers and improve the applicability of this utility model.
[0037] The depth of the flow guide trough 6 gradually increases from the midpoint to both ends along the length of the base plate 1. This design helps guide the fluid to distribute and flow more evenly on the base plate 1. Due to the gradual increase in the depth of the flow guide trough, the fluid experiences a gradually increasing guiding force during flow, thus flowing more smoothly from the middle to both ends of the base plate 1. This helps reduce local accumulation and eddy currents of the fluid on the tray, improving fluid dynamics performance.
[0038] Gradually increasing channel depth allows for more efficient handling of slurries with varying flow rates and concentrations. When the slurry flow rate is high or the concentration is high, a deeper channel provides better fluid flow and greater handling capacity, ensuring stable operation of the pallet even under high load conditions.
[0039] The working principle of the sulfur absorption tower alloy tray provided by this utility model is as follows:
[0040] The flue gas rises from the space beneath the tray and passes through the guide hole 5. Due to the special design of the guide hole 5, including the arc-shaped hole 51 and the guide plate 52, the flue gas can pass through more smoothly and the resistance to fluid flow is reduced. At the same time, the guide plate 52 guides the flue gas, preventing it from accumulating and forming a "lifting" effect, ensuring that the flue gas is evenly distributed above the tray.
[0041] The slurry flows down from above the tray, passing through the guide groove 6 and guide hole 5 on the base plate 1. The depth of the guide groove 6 gradually increases from the midpoint to both ends along the length of the base plate 1. This design helps guide the slurry to be more evenly distributed and flowed on the base plate 1. When the slurry passes through the arc-shaped hole 51, its trapezoidal cross-section design, which is narrower at the top and wider at the bottom, facilitates the smooth passage of the slurry.
[0042] Above the tray, flue gas and slurry interact. The desulfurizing agent in the slurry reacts chemically with sulfur oxides in the flue gas, thereby absorbing sulfur. The tray design ensures sufficient contact between the flue gas and slurry, improving sulfur absorption efficiency.
[0043] The tray design also takes into account hydrodynamic performance. By optimizing the shape and layout of the guide groove 6 and guide hole 5, local accumulation and eddy currents of fluid on the tray are reduced, improving the flow velocity and uniformity of the fluid.
[0044] The alloy tray for sulfur absorption towers provided by this utility model has the following advantages: By optimizing the shape and layout of the guide channels and guide holes, the desulfurization effect is enhanced, while reducing slurry deposition and scaling problems, keeping the tray clean and extending its service life. Its hydrodynamic performance is excellent, improving fluid flow velocity and uniformity. The tray has a simple and stable structure, low manufacturing cost, and the opening parameters can be adjusted according to the design requirements of different desulfurization systems, making it highly adaptable. Therefore, this tray becomes a high-efficiency component in sulfur absorption tower systems, helping to improve desulfurization efficiency and reduce operating costs.
[0045] The present invention has been further described above with reference to specific embodiments. However, it should be understood that the specific description herein should not be construed as limiting the substance and scope of the present invention. Various modifications made by those skilled in the art to the above embodiments after reading this specification are all within the scope of protection of the present invention.
