Description

[Technical Field]

[0001] This invention relates to the technical field of desulfurization towers, and in particular to an efficiency-enhancing device for wet desulfurization spray towers. [Background Technology]

[0002] Currently, my country's thermal power, steel, metallurgy, and cement industries primarily employ wet desulfurization processes to remove sulfur dioxide from flue gas. The desulfurization tower is the most critical core equipment in a wet flue gas desulfurization system, and can be categorized into spray towers, bubbling towers, and liquid column towers based on their different technical characteristics. To improve the efficiency of spray towers in removing pollutants such as SO2, patent CN206566916U discloses a porous tray for an ultra-clean emission tower for boiler flue gas, and patent CN203971740U discloses an improved alloy porous liquid-holding layer device for desulfurization towers, which can improve desulfurization efficiency.

[0003] However, the existing technologies have some shortcomings: the upper edge of the stiffeners of the modular components uses a flanged design, which increases flue gas resistance and is not conducive to energy saving; the modular components are connected by dense bolts, which makes the manufacturing process more complicated, the assembly more complex, the equipment and operating costs higher, and the maintenance more difficult; the U-shaped clips are prone to causing horizontal swaying and detachment of the modular components, and the horizontal fixing strength needs to be improved; the tower wall fixing clips are not easy to tighten during installation, and the modular components are prone to detachment; all clips need to be spot welded after installation, but the anti-corrosion layer of the support beam and tower wall is generally made of flammable materials, increasing safety hazards. Further improvements are needed in terms of structure, safety, and reliability. [Summary of the Invention]

[0004] The purpose of this invention is to solve the problems in the prior art and propose an efficiency-enhancing device for wet desulfurization spray towers. The manufacturing process is simple, and the installation and maintenance are simple and convenient. It does not require spot welding for fixing and the installation is firm and reliable. At the same time, it can reduce flue gas resistance, improve desulfurization efficiency, and achieve energy saving and efficiency enhancement.

[0005] To achieve the above objectives, this invention proposes an efficiency-enhancing device for a wet desulfurization spray tower. The device is installed on the inner wall of the tower body below the spray layer. It includes several supporting beams arranged side-by-side within the tower body, a supporting plate installed on the inner wall of the tower body, several efficiency-enhancing unit components fixed above the supporting beams and the supporting plate, multiple central fixing components that fix the efficiency-enhancing unit components near the center of the tower body to the supporting beams, and multiple edge fixing components that fix the efficiency-enhancing unit components near the edges of the tower body to the supporting plate. Both ends of the supporting beams are fixed to the inner wall of the tower body. The supporting plate has a ring structure and is installed on the inner wall of the tower body. The efficiency-enhancing unit components have evenly distributed circular holes. A U-shaped flat steel bar is provided below the central fixing components. The U-shaped flat steel is clamped below the support beam. Two first fasteners are symmetrically installed on the U-shaped flat steel, which are used to connect and fix two adjacent efficiency enhancement unit components. The edge fixing component is installed below the support plate. An L-shaped flat steel is provided below the edge fixing component. An insertion groove is formed between the L-shaped flat steel and the lower wall of the efficiency enhancement unit component. The L-shaped flat steel is provided with a second fastener for connecting the efficiency enhancement unit component.

[0006] Preferably, the enhancement unit assembly further includes a perforated plate, which has a plurality of circular holes of the same size evenly distributed. The perforation rate of the perforated plate is 45-60%, the width a of the perforated plate is 300-1000 mm, the length b is 400-3000 mm, and the thickness is 2-5 mm. The perforated plates are arranged at equal intervals, and there is a gap m between adjacent enhancement unit assemblies, where m is 10-100 mm.

[0007] Preferably, a reinforcing rib is provided above the efficiency enhancement unit component. The reinforcing rib includes a longitudinal rib and a plurality of transverse ribs arranged at equal intervals along the length of the longitudinal rib. The transverse ribs are symmetrically arranged on both sides of the longitudinal rib. The height of the transverse ribs and the longitudinal ribs are both 50-200mm, and the thickness is both 2-5mm. The transverse ribs and the longitudinal ribs are arranged perpendicularly to each other.

[0008] Preferably, the central fixing component further includes a pressure plate, which is disposed between the A-type nut and the enhancement unit component to press two adjacent enhancement unit components together. The first fastener includes an A-type screw and two A-type nuts. The upper end of the A-type screw is threaded and has two A-type nuts installed. The lower end of the A-type screw is fixed to the U-shaped flat steel by welding. The pressure plate has two through holes symmetrically provided for the A-type screw to pass through.

[0009] Preferably, the second fastener includes a B-type screw, two B-type nuts, and a washer. The upper end of the B-type screw is threaded and fitted with two B-type nuts. The lower end of the B-type screw is fixed to an L-shaped flat steel bar by welding. The washer is installed between the B-type nuts and the screw.

[0010] Preferably, corrosion-resistant rubber material is provided between the efficiency enhancement unit component and the support beam, and between the U-shaped flat steel and the support beam.

[0011] Preferably, the inner wall of the tower body has an annular protrusion extending toward the center, the cross-sectional shape of the annular protrusion is U-shaped, and the interior of the annular protrusion has a hollow cavity. One end of the support plate is connected to the tower body, and the other end extends into the hollow cavity of the annular protrusion. Corrosion-resistant rubber material is provided between the upper wall of the annular protrusion and the efficiency enhancement unit assembly, and between the lower wall of the annular protrusion and the L-shaped flat steel.

[0012] The beneficial effects of this invention are as follows: By adding reinforcing ribs to the perforated plate, the strength of the perforated plate is enhanced, preventing deformation; the central fixing component prevents the efficiency-enhancing unit components from swaying left and right, and the added pressure plate on the central fixing component facilitates pressing the perforated plate; the edge fixing component effectively fixes the efficiency-enhancing unit components close to the inner wall of the tower, and the added corrosion-resistant rubber material effectively avoids surface cracking of the support beams and support plates. Spot welding is not required for fixing, ensuring a firm and reliable installation; simultaneously, it reduces flue gas resistance, improves desulfurization efficiency, and achieves energy saving and efficiency enhancement.
