Description

Technical Field

[0001] This utility model relates to the technical field of flue gas denitrification equipment, specifically to a denitrification catalyst support structure. Background Technology

[0002] Denitrification is a necessary step before flue gas is emitted into the air, aiming to remove nitrogen oxides from the flue gas. Currently, common flue gas denitrification methods generally involve ammonia injection followed by mixing the flue gas with a denitrification catalyst for nitrogen oxide removal. The denitrification catalyst is typically mounted on a frame, which is then connected to the denitrification tower to ensure a stable connection. However, existing denitrification catalyst support structures have the following drawbacks: several catalyst units are arranged on the frame, and when a catalyst unit becomes clogged and affects efficiency, requiring replacement, the close arrangement makes disassembly and replacement inconvenient, thus affecting maintenance efficiency. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of the aforementioned background technology by providing a denitrification catalyst support structure that facilitates the disassembly, maintenance, or replacement of individual catalyst units.

[0004] To achieve the above objectives, this utility model provides a denitrification catalyst support structure, which adopts the following technical solution.

[0005] A denitrification catalyst support structure includes two sets of opposing support plates, each L-shaped. Vertically arranged fixing plates are provided on the support plates, each fixing plate including an L-shaped first fixing plate and a T-shaped second fixing plate. The first fixing plate is located on both sides of the support plate, and the second fixing plate is located between the two ends of the support plate. Vertical grooves are provided on both the first and second fixing plates, and adjusting plates are provided at the grooves. The adjusting plates slide up and down along the grooves. A connecting plate is provided on the side of the adjusting plate, and the connecting plate is attached to the other side wall of the first and second fixing plates. An extension plate extending towards the other support plate is provided below the adjusting plate. The four sets of extension plates on the two support plates are used to support a denitrification catalyst unit.

[0006] A further improvement of the denitrification catalyst support structure of this utility model is that the two ends of the support base plate are provided with reinforcing connecting rods.

[0007] A further improvement of the denitrification catalyst support structure of this utility model is that the upper end of the connecting plate is higher than the adjusting plate, and the adjusting plate is provided with a horizontal plate, which is used to limit the denitrification catalyst unit module.

[0008] A further improvement of the denitrification catalyst support structure of this utility model is that the two ends of the horizontal plate are connected to the second horizontal plate by connecting plates, and there is a gap between the second horizontal plate and the horizontal plate.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] This invention features an adjustable plate that can slide up and down, allowing the denitrification catalyst unit installed on the adjustable plate to move upwards individually. This facilitates the maintenance or replacement of a single denitrification catalyst and improves operational convenience. On the other hand, the horizontal plate further ensures installation stability, and the second horizontal plate facilitates the lifting and replacement of a single denitrification catalyst.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] like Figure 1 and Figure 2 As shown, a denitrification catalyst support structure includes two sets of opposing support base plates 1. The support plates are L-shaped, comprising horizontal and vertical sections. Vertically arranged fixing plates are provided on the horizontal sections of the support base plates, and the connection method can be welding. The fixing plates include an L-shaped first fixing plate 2 and a T-shaped second fixing plate 3. The first fixing plate is located on both sides of the support base plates, and the second fixing plate is located between the two ends of the support base plates. Both the first and second fixing plates have vertical grooves 4, which are located on the sidewalls of the vertical sections of the support base plates where they contact each other. An adjusting plate 5 is provided at each groove, sliding up and down along the groove. A connecting plate 6 is provided on the side of the adjusting plate, and the adjusting plate and connecting plate can be integrally formed. The connecting plate is attached to the other sidewall of the first and second fixing plates, specifically, it can be fixedly connected by bolts or other fasteners. An extension plate 7 is provided below the adjusting plate, extending to one side of the other support base plate. Four sets of extension plates on the two support base plates are used to support a denitrification catalyst unit.

[0016] Furthermore, reinforcing connecting rods are provided at both ends of the two supporting base plates to improve the connection stability between the supporting base plates.

[0017] Furthermore, the upper end of the connecting plate is higher than the adjusting plate, and the adjusting plate is provided with a horizontal plate 8, which is used to limit the denitrification catalyst unit module. Both ends of the horizontal plate are connected to a second horizontal plate 9 via connecting plates, with a gap between the second horizontal plate and the horizontal plate. The horizontal plate further limits the catalyst unit module, while the second horizontal plate facilitates overall lifting. The connection between the horizontal plate, the second horizontal plate, and the connecting plate can be achieved by connecting plates.

[0018] The working principle of this utility model is as follows: the denitrification catalyst unit module is arranged on the extension plate and can be connected and fixed with the adjustment plate and the connecting plate. Then, the catalyst unit, the adjustment plate, the connecting plate, and the extension plate are placed on the two supporting base plates from top to bottom. Then, the connecting plate is connected to the first and second fixing plates. Then, the horizontal plate and the second horizontal plate are arranged. When a denitrification catalyst unit module is blocked and needs to be replaced, the connecting plate is disconnected from the fixing plate, the second horizontal plate is lifted, and the single catalyst unit is removed from the overall structure, making the replacement operation convenient.

[0019] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
