Description

Technical Field

[0001] This utility model relates to the technical field of industrial denitrification devices, and in particular to a honeycomb catalyst structure for a denitrification SCR system. Background Technology

[0002] Currently, the domestic approach to ultra-clean emissions involves adding a catalyst layer. However, this increases the cost of the reactor structure. Furthermore, due to limitations in catalyst height, in some power plants where the reactor volume cannot be increased further, insufficient catalyst can lead to failure to meet ultra-clean emission standards. Consequently, the power plant's output is restricted, resulting in direct economic losses for the enterprise.

[0003] The existing announcement number CN206823806U discloses a honeycomb catalyst structure for a denitrification SCR system, including a frame and catalyst units. The frame surrounds the catalyst units to form a catalyst module. The key technology is that the catalyst modules are connected by positioning connecting blocks. The catalyst modules are connected by connecting blocks, and two catalyst sections can be loaded in the same layer. This breaks through the limitation of the length of the catalyst unit, which means that up to twice the original amount of catalyst can be loaded in one layer. This solves the problem of catalyst loading that has long been difficult to solve in the industry. The connecting blocks control the alignment of the upper and lower modules to ensure that they are not tilted. The force between the upper and lower modules can be smoothly transmitted through the steel plate around the module without pressing on the catalyst and damaging it.

[0004] However, the honeycomb catalyst structure of the aforementioned denitrification SCR system makes it inconvenient to install and disassemble the catalyst structure during use, and the catalyst structure is not easy to replace, resulting in a decrease in catalytic efficiency over a long period of use. Utility Model Content

[0005] The purpose of this invention is to provide a honeycomb catalyst structure for a denitrification SCR system, which solves the problems of inconvenient installation and disassembly of the catalyst structure and the difficulty in replacing the catalyst structure during use, leading to a decrease in catalytic efficiency over a long period of use.

[0006] To achieve the above objectives, this utility model provides a honeycomb catalyst structure for a denitrification SCR system, including a mounting frame, a mounting assembly, and a fixing assembly. The mounting assembly includes a support plate, a mounting base, mounting bolts, and positioning columns. Multiple support plates are fixedly connected to the mounting frame and located in the center of the frame. The mounting base is fixedly connected to the support plates and located between them. The mounting bolts are detachably connected to the mounting base and pass through it. Multiple positioning columns are fixedly connected to the mounting base and located at the top of the base. The fixing assembly is connected to the mounting frame.

[0007] The mounting assembly further includes multiple inserts, each of which is fixedly connected to the mounting frame and located on the outside of the mounting frame.

[0008] The mounting frame has multiple slots on its outer side, the mounting base has two mounting holes on its top, two limiting holes on its top, and multiple fixing grooves on its outer side.

[0009] The fixing assembly includes a rotating shaft, a rotating seat, a pressure plate, and a limiting block. There are multiple rotating shafts, each rotatably connected to the mounting frame and located inside the mounting frame. There are multiple rotating seats, each rotatably connected to a rotating shaft and located outside the rotating shaft. There are multiple pressure plates, each fixedly connected to a rotating seat and located above the support plate. There are multiple limiting blocks, each fixedly connected to a pressure plate and located inside the fixing groove.

[0010] The fixing assembly further includes a fixing plate, fixing bolts, and limiting rods. The fixing plate is detachably connected to the mounting base and is located on top of the mounting base. There are two fixing bolts, which are threaded to the mounting base and pass through the fixing plate and the mounting hole, respectively. There are two limiting rods, which are fixedly connected to the fixing plate and are located inside the limiting hole, respectively.

[0011] This invention discloses a honeycomb catalyst structure for a denitrification SCR system. The mounting frame provides overall support for the device, the support plate provides support and positioning for the honeycomb catalyst, and the mounting base connects to the support plate. Mounting bolts facilitate the installation of the mounting base and mounting frame within the system. Positioning posts guide the position of the fixing plate. In use, the fixing assembly is opened, and the mounting bolts secure the mounting base and mounting frame within the system. The catalyst is then placed on the surface of the support plate, and finally, the fixing assembly is placed over the catalyst surface, facilitating the installation and fixing of multiple catalyst pieces. The combination of multiple inserts and slots allows for the positioning and connection of the mounting frames, enabling multiple mounting frames to be connected together. This significantly improves the catalytic efficiency of the catalyst and solves the problems of inconvenient installation and disassembly of the honeycomb catalyst structure in denitrification SCR systems, which hinders catalyst replacement and leads to reduced catalytic efficiency over long-term use.

[0021] In this specific embodiment, there are multiple support plates 102, each fixedly connected to the mounting frame 101 and located in the middle of the mounting frame 101. A mounting base 103 is fixedly connected to the support plates 102 and located between the multiple support plates 102. A mounting bolt 104 is detachably connected to the mounting base 103 and passes through it. There are multiple positioning posts 105, each fixedly connected to the mounting base 103 and located at the top of the mounting base 103. A fixing assembly is connected to the mounting frame 101. The mounting frame 101 provides support for the entire device. The support plates 102 provide support and limit the position of the honeycomb catalyst. The 03 is used to connect the support plate 102. The mounting bolt 104 facilitates the installation of the mounting base 103 and the mounting frame 101 in the system. The positioning post 105 is used to guide the position of the fixing plate 115. In use, the fixing assembly is opened, and the mounting bolt 104 facilitates the fixing of the mounting base 103 and the mounting frame 101 in the system. Then, the catalyst is placed on the surface of the support plate 102, and finally the fixing assembly is placed on the surface of the catalyst to facilitate the installation and fixing of multiple catalysts. The cooperation of multiple inserts 106 and slots 107 facilitates the limiting and connection of the mounting frame 101, so that multiple mounting frames 101 can be connected together, which significantly improves the catalytic efficiency of the catalyst.

[0022] The number of inserts 106 is multiple, and the multiple inserts 106 are fixedly connected to the mounting frame 101 respectively and are located on the outside of the mounting frame 101. The inserts 106 are used to provide a connection to the mounting frame 101. The insert 106 on the outside of one mounting frame 101 cooperates with the slot 107 of another mounting frame 101 to facilitate the connection of multiple mounting frames 101.

[0024] Furthermore, there are multiple rotating shafts 111, each rotatably connected to the mounting frame 101 and located inside the mounting frame 101.

The pressure plate 113 and the support plate 102 facilitate the fixing of the catalyst. The limiting rods 117 and the positioning post 105 cooperate to position the fixing plate 115, preventing it from shifting during installation. Finally, the fixing bolts 116 secure the fixing plate 115, facilitating the installation and removal of the catalyst.

In use, the fixing assembly is opened, and the mounting bolts 104 facilitate the connection of the mounting base 103 and the mounting frame 101. The catalyst is fixed inside the system, then placed on the surface of the support plate 102, and finally the fixing component is placed on the surface of the catalyst. This facilitates the installation and fixing of multiple catalysts.
