Description

Technical Field

[0001] This utility model relates to the field of oxidation duct technology, and in particular to an oxidation duct support and fixing device. Background Technology

[0002] Oxidation ducts are usually installed in the slurry pool area of ​​the absorption tower. The main function of the oxidation ducts is to send oxidation air into the absorption tower to provide oxygen for the desulfurization reaction. This ensures that the air can be evenly distributed throughout the entire absorption tower, promoting the oxidation reaction of calcium sulfite.

[0003] Currently, most oxidation ducts in thermal power plant absorption towers are fixed using pipe clamps. These clamps secure the ducts to the welded plates of the support beams. The contact surface between the oxidation duct and the horizontal support beam is line contact. The fixing force of the clamp is concentrated at the contact point directly below the duct and the support beam. The oxidation duct is subject to tangential scouring and disturbance from the airflow inside the duct and the slurry outside the duct. Due to the thin wall of the duct, the force is concentrated at this contact point, causing deformation. This deformation leads to loosening of the duct and the clamp. The duct is subjected to long-term disturbance from the airflow and slurry, and friction and collision with the clamp cause wear and damage to the bolt holes of the duct fixing plate, resulting in the clamp falling off and the duct breaking. Therefore, we propose an oxidation duct support and fixing device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a support and fixing device for oxidation ductwork to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An oxidation duct support and fixing device includes an absorption tower body. Several oxidation ducts are arranged on the front side of the absorption tower body. Several sets of main beams are arranged on the front side of the absorption tower body. Support beams are fixedly connected to the sides of each set of main beams that are close to each other. Ribs are welded to the ends of each set of support beams. Two sets of screw holes are opened inside each rib. Bolts are installed inside each set of screw holes. A clamp is fixedly connected to the top of each set of bolts. Each set of clamps is located outside the oxidation duct. A first nut is threaded onto the outer surface of each set of bolts. The first nut is located on the upper part of each set of ribs. A second nut is threaded onto the outer surface of each set of bolts. The second nut is located on the bottom surface of each set of ribs.

[0007] In a further embodiment, the absorption tower body is internally fixedly connected with several support beams.

[0008] In a further embodiment, the weld joint between each set of support beams and ribs is reinforced with glass flake corrosion protection and FRP.

[0009] In a further embodiment, one end of each oxidation duct is fixedly connected to a flange connector, and the outer surface of each flange connector is fixedly connected to a duct inlet.

[0010] In a further embodiment, a first washer is movably connected to the outer surface of each group of bolts, the bottom surface of each group of first washers is in contact with the upper surface of the rib, and the upper surface of each group of first washers is in contact with the bottom surface of the first nut.

[0011] In a further embodiment, a second washer is movably connected to the outer surface of each group of bolts, the upper surface of each group of second washers is in contact with the bottom surface of the rib, and the bottom surface of each group of second washers is connected to the upper surface of the second nut.

[0012] In a further embodiment, each set of bolts has a locking nut threaded onto its outer surface, and the upper surface of each locking nut is in contact with the bottom surface of the second nut.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] By using bolts, a first nut, a second nut, and clamps to encircle the outside of the oxidation duct, a rigid, double-clamp fixing method is formed, which can greatly improve the duct's fixing firmness, effectively limit the radial displacement of the duct, and avoid shaking caused by slurry scouring and disturbance. This solves the problem that the existing oxidation duct commonly uses a single-clamp fixing process, which is prone to duct breakage. Attached Figure Description

[0024] Please see Figure 1-5In this utility model, the oxidation duct support and fixing device includes an absorption tower body 1. The front of the absorption tower body 1 is provided with several oxidation ducts 6, and the front of the absorption tower body 1 is provided with several sets of main beams 8. Each set of main beams 8 has a support beam 7 fixedly connected to its adjacent side. Each set of support beams 7 has a rib plate 9 welded to its end. Each rib plate 9 has two sets of screw holes 10 inside, and each set of screw holes 10 has a bolt 12 inside. Each set of bolts 12 has a clamp 11 fixedly connected to its top. Each set of clamps 11 is located on the oxidation duct 6. On the outside, each set of bolts 12 has a first nut 13 threadedly connected to its outer surface. Each set of first nuts 13 is located on the upper part of the rib plate 9. Each set of bolts 12 has a second nut 14 threadedly connected to its outer surface. Each set of second nuts 14 is located on the bottom surface of the rib plate 9. Through the cooperation of the main beam 8 and the support beam 7, a fixed frame can be formed. Through the cooperation of bolts 12, first nuts 13, second nuts 14 and clamps 11, the frame surrounds the outside of the oxidation duct 6, forming a rigid fixed double clamp fixed method, which can effectively limit the radial displacement of the duct.

[0025] The absorption tower body 1 is internally fixedly connected with several support beams 2, which can enhance the structural strength of the absorption tower body 1.

[0026] The weld joints between each set of support beams 7 and ribs 9 are reinforced with glass flake anti-corrosion coating and FRP, which improves the corrosion resistance of the device and extends its service life.

[0027] Each oxidation duct 6 has a flange connector 4 fixedly connected to one end, and each flange connector 4 has a duct inlet 5 fixedly connected to its outer surface. By providing the flange connector 4, it is easy to replace the duct inlet 5, thus improving the replacement efficiency.

[0028] Each set of bolts 12 has a first washer 15 movably connected to its outer surface. The bottom surface of each set of first washers 15 is in contact with the upper surface of the rib plate 9, and the upper surface of each set of first washers 15 is in contact with the bottom surface of the first nut 13. By providing the first washer 15, the contact panel between the first nut 13 and the rib plate 9 is increased, preventing the rib plate 9 from being damaged due to concentrated force.

[0029] Each set of bolts 12 has a second washer 16 movably connected to its outer surface. The upper surface of each set of second washers 16 is in contact with the bottom surface of the rib plate 9, and the bottom surface of each set of second washers 16 is connected to the upper surface of the second nut 14. By providing the second washer 16, the contact area between the second nut 14 and the rib plate 9 can be increased, preventing the rib plate 9 from being damaged due to concentrated force.

[0030] Each bolt 12 has a threaded anti-loosening nut 3 on its outer surface. The upper surface of each anti-loosening nut 3 is in contact with the bottom surface of the second nut 14. By providing anti-loosening nuts 3, the nuts can be further prevented from loosening, ensuring the fixed state of the oxidation duct 6.

[0031] The working principle of this utility model is as follows:

[0032] During use, several sets of main beams 7 and support beams 7 on the front of the absorption tower body 1 cooperate to form a fixed frame, providing a support base for fixing the oxidation duct 6. The clamp 11 is wrapped around the outside of the oxidation duct 6, and the bolts 12 pass through the screw holes 10 on the rib plate 9. By tightening the first nut 13 located on the upper part of the rib plate 9 and the second nut 14 located on the bottom surface of the rib plate 9, the clamp 11 tightly hugs the oxidation duct 6 through the cooperation of the bolts 12, the first nut 13 and the second nut 14, thus fixing the oxidation duct 6. By fixing the oxidation duct 6 with multiple clamps 11, the radial displacement of the duct is effectively limited, and it is prevented from shaking due to the disturbance of slurry scouring.
