Description

Technical Field

[0001] This utility model belongs to the field of SCR cement catalyst technology, and specifically relates to a packaging module for SCR cement catalyst. Background Technology

[0002] my country has nearly 5,000 cement enterprises, and its output has ranked first in the world for many consecutive years. In 2018, the total national cement output was approximately 2.33 billion tons. The production of cement clinker generates a large amount of... Emissions, and due to the cement industry The high emission concentration and high dust content in the flue gas pose significant challenges to the denitrification work of cement clinker production lines.

[0003] Currently, SCR cement catalysts are commonly used for denitrification of cement production flue gas. These catalysts are typically used in multiple modules to ensure efficient flue gas treatment. Therefore, after production, the SCR cement catalysts require assembly and packaging. Existing packaging modules generally use metal partitions to fix and separate each SCR cement catalyst. However, SCR cement catalysts have inherent dimensional errors during production, and using fixed materials can easily create gaps, making the catalysts less secure. Furthermore, after packaging, the SCR cement catalysts require lifting equipment for transportation and installation. While existing packaging modules include lifting lugs, these lugs protrude above the module itself, resulting in wasted space during storage and stacking. Therefore, a new packaging module for SCR cement catalysts is needed. Utility Model Content

[0004] The purpose of this invention is to provide a packaging module for SCR cement catalysts. By installing lifting lugs on the outer wall of the packaging side panel, and using flat rectangular lugs, a stable connection with the hooks is ensured while reducing the volume of the lifting lugs and the overall maximum extension of the packaging module. This overcomes the shortcomings of existing SCR cement catalyst packaging modules, which waste a lot of space during storage and stacking. The specific technical solution is as follows: A packaging module for SCR cement catalyst includes packaging side panels connected end to end to form a square tube with openings at the front and rear ends, respectively. It also includes isolation cotton, a limiting support assembly, and lifting lugs. The isolation cotton is installed inside the square tube for fixing and separating the SCR cement catalyst. The limiting support assembly is installed at the rear end for limiting and supporting the SCR cement catalyst. The lifting lugs are symmetrically installed on the left and right outer walls of the square tube. Each lifting lug is a flat square tube with a vertical through-hole.

[0005] Preferably, the lifting lugs are arranged symmetrically about the middle surfaces of the upper and lower sides of the square tube.

[0006] Preferably, a reinforcing plate is installed on the outer wall of the packaging side panel, and the reinforcing plate is connected to each other end to end around the outer wall of the square tube.

[0007] Preferably, the reinforcing plate has at least one perforation.

[0008] Preferably, the limiting support assembly includes a vertical support rod, limiting baffles, and a fixed frame. A connecting plate is installed on the edge of the opening at the rear end. The fixed frame is fitted onto the inner wall of the connecting plate. The fixed frame and the connecting plate are fixedly connected by bolts. The two ends of the vertical support rod are respectively connected to the inner walls of the upper and lower sides of the fixed frame. Multiple vertical support frames are arranged in an array along the horizontal direction within the fixed frame. Multiple limiting baffles are arranged in an array on the vertical support rod. The limiting baffles are located on the side of the vertical support rod closer to the front end.

[0009] Preferably, the spacing between the vertical support rods is equal to the width of the SCR cement catalyst, and the gap between the vertical support rods and the SCR cement catalyst is aligned.

[0010] Preferably, it also includes a horizontal support rod, the two ends of which are respectively connected to the inner sidewall of the fixed frame. The horizontal support rod is perpendicular to and passes through the vertical support rod, and a plurality of the horizontal support rods are distributed along the vertical support rod array.

[0011] Preferably, the limiting baffle is located at the intersection of the horizontal and vertical gaps of the SCR cement catalyst, and the limiting baffle is in contact with four SCR cement catalysts simultaneously.

[0012] Preferably, the packaging side panel, limiting support assembly, and lifting lugs are made of only high-strength sheet metal.

[0013] Compared with existing technologies, this utility model has the following beneficial effects: 1. This utility model installs the lifting lugs on the outer side wall of the packaging side panel. The lifting lugs are flat rectangular tubes. While ensuring a stable connection with the hook, the volume of the lifting lugs is reduced and the overall maximum size of the packaging module is extended, which facilitates the stacking and storage of the packaging module as a whole, thereby increasing the utilization rate of space.

[0014] 2. This invention uses insulating cotton instead of metal to separate and fix the SCR cement catalyst. Because the insulating cotton is elastic, it can fully fill the gaps between the SCR cement catalysts according to production errors, ensuring the stability of the SCR cement catalyst within the packaging module. At the same time, because the insulating cotton is relatively soft, it will not damage the SCR cement catalyst when squeezed, thus ensuring that the SCR cement catalyst is not damaged by impacts.

[0022] 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.

[0023] The core of SCR cement catalyst 8's catalytic denitrification of cement production flue gas is the "selective catalytic reduction" reaction. This process begins by injecting ammonia as a reducing agent into the flue gas. When the mixed gas flows through the SCR cement catalyst 8 located at the kiln tail (usually after the preheater, at a temperature of approximately 280-350℃), the main pollutants in the flue gas, nitrogen oxides, react chemically with ammonia on the catalyst surface. The catalyst (usually with TiO2 as a support and V2O5 as the main active component) plays a crucial role in significantly reducing the activation energy of the reaction and highly selectively promoting the efficient and rapid generation of harmless nitrogen and water from NOx and NH3 in the presence of oxygen, thereby achieving removal. To withstand the harsh conditions of high dust and high abrasion in cement kiln flue gas, the catalyst undergoes special processes such as high-pressure extrusion, high-temperature sintering, and end hardening during production, endowing it with extremely high mechanical strength and wear resistance. This ensures that it maintains stable catalytic activity even under long-term scouring, ultimately achieving a denitrification efficiency of over 90%.

[0024] Next, refer to Figures 1 to 5 The working principle of this embodiment will be described in detail so that those skilled in the art can better understand this utility model: A packaging module for SCR cement catalyst 8 includes a packaging side plate 1. The packaging side plate 1 is connected end to end by welding to form a square tube. The two ends of the square tube are the front end 2 and the rear end 3, respectively. When packaging SCR cement catalyst 8, the operator will put SCR cement catalyst 8 into the square tube from the front end 2.

[0025] refer to Figure 5 The packaging side panels 1 can also be connected by bolts. Compared with welding, bolt connection allows the packaging module to be recycled and reused. Moreover, since it can be disassembled and adjusted, the requirements for technicians will be reduced. However, it requires more space overall and has a higher space cost than welding. The two methods can be selected according to the actual situation.

[0026] A packaging module for SCR cement catalyst 8 also includes isolation cotton 4, limiting support assembly 5, and lifting lugs 6. The isolation cotton 4 is installed inside a square tube to fix and separate the SCR cement catalyst 8. Due to its elasticity, the isolation cotton 4 can fully fill the gaps between the SCR cement catalyst 8 according to production errors, ensuring the stability of the SCR cement catalyst 8 within the packaging module. Simultaneously, because the isolation cotton 4 is relatively soft, it will not damage the SCR cement catalyst 8 when squeezed, thus ensuring that the SCR cement catalyst 8 is not damaged by impacts. Furthermore, compared to using metal isolation components, the isolation cotton 4 can significantly reduce the overall weight of the packaging module, reducing transportation costs and lifting difficulty. Since the SCR cement catalyst 8 needs to be used in high-temperature environments, high-temperature resistant materials such as rock wool and aluminum silicate wool can be used inside. The limiting support assembly 5 is installed at the rear end 3 to limit and support the SCR cement catalyst 8, preventing it from moving along the front and rear end directions 3. It also assists in positioning the SCR cement catalyst 8 to ensure it is properly installed during packaging. Lifting lugs 6 are symmetrically welded onto the outer walls of the left and right sides of the square tube. Lifting lugs 6 are flat rectangular tubes with vertical through-holes. When lifting and transporting the packaging module, a hook can be inserted through the lower through-hole of the lifting lug 6 to hook it, forming a secure connection. The flat rectangular shape of the lifting lug 6 ensures a stable connection with the hook while minimizing its volume and the overall extension of the packaging module, facilitating the stacking and storage of the entire module and increasing space utilization.

[0027] The lifting lugs 6 are symmetrically arranged about the middle of the upper and lower sides of the square tube, which makes it convenient for operators to lift the tube whether the top or bottom is facing upwards, thus improving the ease of use of the packaging module.

[0028] A reinforcing plate 7 is installed on the outer wall of the packaging side panel 1. The reinforcing plate 7 is connected end to end around the outer wall of the square tube. The reinforcing plate 7 is used to increase the overall strength of the packaging module and reduce deformation. The reinforcing plate 7 has at least one cutout, which can reduce the overall weight of the module while ensuring overall rigidity and strength.

[0029] The limiting support assembly 5 includes a vertical support rod 51, limiting baffles 52, and a fixing frame 53. A connecting plate 9 is welded and installed on the edge of the opening at the rear end 3. The fixing frame 53 is fitted onto the inner wall of the connecting plate 9, and the fixing frame 53 and the connecting plate 9 are fixedly connected by bolts. The two ends of the vertical support rod 51 are welded and connected to the inner walls of the upper and lower sides of the fixing frame 53, respectively. Through the cooperation of the fixing frame 53 and the vertical support rod 51, the support capacity and stability of the module can be further enhanced. Multiple vertical support frames are arranged in an array along the horizontal direction within the fixing frame 53. Multiple limiting baffles 52 are arranged in an array on the vertical support rod 51. The limiting baffles 52 are located on the side of the vertical support rod 51 closer to the front end 2. The limiting baffles 52 are generally diamond-shaped, circular, or rectangular, etc., and are used to prevent the SCR cement catalyst 8 from moving towards the rear end 3.

[0030] The spacing between the vertical support rods 51 is equal to the width of the SCR cement catalyst 8, and the gap between the vertical support rods 51 and the SCR cement catalyst 8 is aligned, so that the vertical support rods 51 will not obstruct the SCR cement catalyst 8 and will not affect the SCR cement catalyst 8's flue gas treatment efficiency.

[0031] The two ends of the transverse support rod 54 are connected to the inner sidewall of the fixed frame 53. The transverse support rod 54 is perpendicular to and passes through the vertical support rod 51. Multiple transverse support rods 54 are arranged in an array along the vertical support rod 51. The transverse support rods 54 can further enhance the support capacity of the limiting support assembly 5. (Reference) Figure 3 The horizontal support rod 54 can also be used with the lifting lug 6 to lift the entire packaging module, thereby reducing the number of lifting lugs 6 that need to be installed and reducing material costs.

[0032] The limiting baffle 52 is located at the intersection of the horizontal and vertical gaps of the SCR cement catalyst 8. The limiting baffle 52 is in contact with all four SCR cement catalysts 8 at the same time, thereby ensuring that the limiting baffle 52 provides stable support for the SCR cement catalyst 8 while minimizing the total area of ​​the limiting baffle 52. This reduces the obstruction of the limiting baffle 52 to the SCR cement catalyst 8 and prevents the limiting baffle 52 from affecting the flue gas treatment efficiency of the SCR cement catalyst 8.

[0033] The packaging side panel 1, the limiting support component 5, and the lifting lug 6 are made only of high-strength plates, such as Q345 steel or No. 20 boiler steel.

[0034] The usage process of this utility model is as follows: When loading the SCR cement catalyst 8 into the packaging module, preparatory work is required first, including checking the module structure, the limiting support component 5, and the integrity of the catalyst. The operator first uses a packaging side plate 1 as a base plate and bolts the limiting support component 5 onto the connecting plate 9. Then, the SCR cement catalyst 8 is stacked on the packaging side plate 1 to form a module. The gaps between the SCR cement catalyst 8 are aligned with the vertical support rods, and the rear end face of the SCR cement catalyst 8 is in close contact with the limiting baffle 52 to achieve reliable limiting. Isolation cotton 4 is placed between the SCR cement catalyst 8 to separate them. Finally, the isolation cotton 4 is used to wrap and fix the outer wall of the stacked SCR cement catalyst 8 module. The operator then welds or bolts the remaining packaging side plates 1 around the SCR cement catalyst 8 module on the base plate to form the complete packaging module. Finally, a final inspection is performed to ensure that all catalysts are securely in place and that the isolation cotton 4 is fully filled.
