Description

Technical Field

[0001] This invention relates to the field of air pollution control technology, specifically to a method for testing the wear strength of the support mesh of an SCR denitrification catalyst module. Background Technology

[0002] Nitrogen oxides (NOx) are among the major pollutants emitted into the atmosphere by human activities, primarily consisting of nitric oxide and nitrogen dioxide. Combustion sources of NOx mainly originate from the combustion of fossil fuels such as coal, oil, and natural gas. NOx in flue gas primarily exists in the form of NO, accounting for approximately 95% of initial emissions. NOx emissions cause acid rain, photochemical smog, ozone layer depletion, and many other environmental problems, significantly threatening human health. my country's abundant coal reserves and scarce oil and natural gas resources mean that coal-fired power plants, which dominate the country's power supply sector, rely heavily on coal as their primary fuel, a situation unlikely to change in the short term. Statistics show that coal combustion accounts for 70% of total fuel emissions in my country, and data from the China Environmental Statistics Yearbook indicates that national NOx emissions reached 19.7 million tons in 2020.

[0003] Selective Catalytic Reduction (SCR) of NH3, or NH3-SCR for short, is currently the most mature and widely used denitrification technology. The introduction of various new environmental protection policies has spurred the large-scale promotion of SCR technology. This technology has advantages such as high efficiency, good selectivity, and technological maturity, and is widely used in coal-fired power plants. Currently, in the flue gas denitrification systems of coal-fired power plants in China, the most widely used catalyst is a metal oxide catalyst, which uses anatase titanium dioxide as a carrier to support vanadium oxide as the active material, supplemented by tungsten oxide or molybdenum oxide as a co-catalyst. The key to NH3-SCR technology is a high-performance denitrification catalyst, currently VW / TiO2 is commonly used as the flue gas denitrification catalyst. This catalyst was first developed by Japan and Germany in the 1970s and has gradually been widely adopted in developed countries. Existing flue gas denitrification catalysts mainly use honeycomb SCR denitrification catalysts. These catalysts are generally packaged in iron boxes, with catalyst module support mesh installed at the inlet of the iron box. Based on existing experience, after the catalyst module is installed in the power plant, its mechanical strength is one of the most important factors affecting the catalyst's service life during operation. Therefore, for the entire catalyst module, in addition to the mechanical strength of the catalyst itself, the wear strength of the support mesh of the catalyst module also directly affects the catalyst's service life. Currently, there is no specific testing method for the wear strength of the catalyst module support mesh, both domestically and internationally. Therefore, mastering an efficient and reasonable testing method for the wear strength of the catalyst module support mesh is of positive significance for catalyst production.

[0035] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of the present invention.

Therefore, unless otherwise stated, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature; "multiple" means two or more. The term "comprising" and any variations thereof mean a non-exclusive inclusion, the possibility of the presence or addition of one or more other features, units, components, and / or combinations thereof.

[0037] Furthermore, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium, or internal connections between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0038] The first aspect of this invention provides a device for testing the wear strength of the support mesh of an SCR denitrification catalyst module, such as... Figure 2-3 As shown, the SCR denitrification catalyst module support mesh wear strength testing device includes a blower 1 and an automatic feeder 3;

[0039] One input end of the test pipe 2 is connected to the output end of the blower 1, and the other input end is connected to the output end of the automatic feeder 3. The output end of the test pipe 2 is connected to an abrasive collection device 5. The test pipe 2 includes a test sample area 4 for placing a support mesh of a set shape.

[0040] Based on the above technical solution, the wear strength of the support mesh of the denitrification catalyst module can be tested quickly and accurately, allowing for the selection of the most cost-effective support mesh. This not only benefits industrial applications but also reduces the overall production cost of the denitrification catalyst, lowering the procurement and replacement costs for power plants and contributing to environmental protection. The automatic feeder 3, resembling a funnel, is used to add quartz sand into the test pipe 2. The support mesh can be made of 304 stainless steel, 65 manganese steel, or galvanized iron wire.

[0041] The SCR denitrification catalyst module support mesh wear strength testing device of the present invention has a test sample area 4 located behind the automatic feeder 3. In a specific embodiment, the diameter of the pipe at the end of the test sample area 4 closest to the wear agent collection device is slightly smaller than the diameter of the pipe at the end closest to the automatic feeder, thereby ensuring that the support mesh is always within the test sample area 4. In a more specific embodiment, the test sample area 4 is provided with a movable cover plate, so that the cover plate can be opened as needed to place the support mesh into the test sample area 4, and the support mesh can be removed after the test is completed.

[0042] In a preferred embodiment, the SCR denitrification catalyst module support mesh wear strength testing device of the present invention can also set up a comparison sample area in the test pipe 2 between the blower 1 and the automatic feeder 3, so as to compare with the test sample area.

[0043] In a specific embodiment of the SCR denitrification catalyst module support mesh wear strength testing device of the present invention, the blower 1 includes an air volume adjustment mechanism for outputting air at a set speed as required, thereby adjusting the air speed to match the feeding speed of the automatic feeder 3, and thus better testing the wear strength of the support mesh.

[0044] In a specific embodiment of the SCR denitrification catalyst module support mesh wear strength testing device of the present invention, the wear agent collection device 5 is connected to a dust removal device 6 to prevent untreated dust from entering the environment and causing pollution to the construction site or the environment. The wear agent collection device 5 can be any device for storing quartz sand, such as a storage box or cabinet.

[0045] The second aspect of this invention also provides a method for testing the wear strength of the support mesh of an SCR denitrification catalyst module, such as... Figure 1 As shown, the method includes the following steps:

[0046] S1. Cut the support mesh into the set shape;

[0047] S2. Place the support mesh of the set shape into the oven for drying, and after drying, let it cool naturally at room temperature and weigh it.

[0048] S3. After wrapping the support mesh of the set shape with sponge, place it in the test pipe 2 of the wear strength test device;

[0049] S4. Use blower 1 to blow air into test pipe 2 at a set wind speed, and add the first set mass of quartz sand into automatic feeder 3 to start the wear strength test experiment.

[0050] S5. During the test, at set intervals, add the second set mass of quartz sand into the automatic feeder 3 until the third set mass of quartz sand has been added.

[0051] S6. After the test is completed, turn off the blower 1, take out the support mesh of the set shape, put it into the oven for drying, and then place it at room temperature to cool naturally and weigh it after drying.

[0052] S7. Calculate the wear intensity of the support mesh with the set shape based on the wear amount of the support mesh with the set shape.

[0053] In the specific implementation of the SCR denitrification catalyst module support mesh wear strength test method of the present invention, the support mesh can be cut into various shapes. Preferably, for example, the support mesh can be cut into an L-shape, a U-shape or a rectangle. Most preferably, the support mesh is cut into a U-shape, so that the support mesh can be better tested in the test pipe 2.

[0054] In the specific implementation of the SCR denitrification catalyst module support mesh wear strength test method of the present invention, in steps S2 and S6, the support mesh of the set shape is treated in the same way in the oven. The drying time and temperature in the oven are 30-180 minutes and 80-160 degrees Celsius, respectively. Preferably, the drying temperature in the oven is 100-120 degrees Celsius. Most preferably, the drying time and temperature in the oven are 120 minutes and 105 degrees Celsius, respectively, so that the support mesh is fully dried and the weighing accuracy is guaranteed.

[0055] In a specific embodiment of the SCR denitrification catalyst module support mesh wear strength test method of the present invention, step S3 involves wrapping the support mesh of a set shape with a sponge. Specifically, taking a U-shaped support mesh as an example, a square sponge is used to wrap the parallel opposite sides of the U-shaped support mesh, so that sand and dust pass through the non-parallel sides of the U-shaped support mesh, thereby avoiding wear caused by friction between the U-shaped support mesh and the pipe wall in the test sample area 4, and ensuring the accuracy of the wear strength measurement of the U-shaped support mesh.

[0056] In a specific embodiment of the SCR denitrification catalyst module support mesh wear strength test method of the present invention, in step S4, a blower 1 is used to blow air into the test pipe 2 at a set wind speed. Specifically, this includes: the blower 1 blows air into the test pipe 2 at a wind speed of 1-30 m / s, preferably, the blower 1 blows air into the test pipe 2 at a wind speed of 5-20 m / s, more preferably, the blower 1 blows air into the test pipe 2 at a wind speed of 12-16 m / s, and most preferably, the blower 1 blows air into the test pipe 2 at a wind speed of 16 m / s, so that the wind speed matches the speed at which the automatic feeder 3 feeds the quartz sand, thereby achieving the optimal test effect.

[0057] In the specific implementation of the SCR denitrification catalyst module support mesh wear strength test method of the present invention, 30-80 mesh quartz sand is selected, preferably 40-70 mesh quartz sand is selected, and most preferably 60 mesh quartz sand is selected, so as to avoid excessive test time while ensuring test effect.

[0058] The SCR denitrification catalyst module support mesh wear strength test method of the present invention, in a specific embodiment, has the following settings: the first set mass is 1-15 kg, the second set mass is 3-10 kg, and the third set mass is 20-30 kg; preferably, the first set mass is 3-12 kg; most preferably, the first set mass is 6 kg, the second set mass is 5 kg, and the third set mass is 26 kg. 26 kg of quartz sand is added to the automatic feeder 3 in increments of 6, 5, 5, 5, 5 kg, thus ensuring the uniformity of feeding by the automatic feeder 3 and guaranteeing the accuracy of the test results. In another specific embodiment, the set time is 10-40 minutes, most preferably 20 minutes. The total time for the wear strength test is 80-180 minutes, preferably 120 minutes, to ensure the accuracy of the test results. Here, the total time for the wear strength test mainly refers to the time from the initial addition of quartz sand to the automatic feeder 3 until all the last added quartz sand is used up.

[0059] The present invention will be described in detail below through embodiments, but the scope of protection of the present invention is not limited thereto.

[0060] like Figure 1-3As shown, the wear strength test device for the SCR denitrification catalyst module support mesh is used. The wear strength test device includes a blower 1 and an automatic feeder 3. One input end of the test pipe 2 is connected to the output end of the blower 1, and the other input end is connected to the output end of the automatic feeder 3. The output end of the test pipe 2 is connected to an abrasive collection device 5. The test pipe 2 includes a test sample area 4 for placing a support mesh of a set shape. The blower 1 includes an airflow regulating mechanism for outputting air at a set airflow speed as required. The abrasive collection device 5 is connected to a dust removal device 6.

[0074] Table 3: Test data on the wear strength of U-shaped support mesh made of galvanized iron wire

[0075]

[0076] As can be seen from Tables 1-3 in Examples 1-3 above, the wear strength test method and device for the SCR denitrification catalyst module support mesh described in this invention can accurately and efficiently test the wear strength of support meshes of various materials.

[0077] To maximize the economic benefits of the selected support mesh while ensuring its usability, the wear strength of the catalyst itself was further tested as follows.

[0078] like Figure 1-3 As shown, the SCR denitrification catalyst module support mesh wear strength testing device is used. The wear strength testing device includes a blower 1 and an automatic feeder 3. One input end of the test pipe 2 is connected to the output end of the blower 1, and the other input end is connected to the output end of the automatic feeder 3.

During the test, 5 kg of 60-mesh quartz sand is added to the automatic feeder 3 every 20 minutes until 26 kg of 60-mesh quartz sand has been added (i.e., added in five batches of 6, 5, 5, 5 kg). After the test, the blower 1 is turned off, the catalyst sample is removed, and it is placed in an oven and dried at 105 degrees Celsius for two hours. After drying, it is allowed to cool naturally at room temperature and weighed. The wear strength of the catalyst sample is calculated based on the amount of wear.

[0081] The test results are shown in Table 4 below.

[0082] Table 4: Test data on the wear intensity of catalyst samples

[0083]

[0084] Comparing Tables 1-3 and 4 above, it can be seen that the wear strength of the support mesh made of 304 stainless steel, manganese steel 65 and galvanized iron wire is better than that of the catalyst sample. At this time, the support mesh made of the material that maximizes economic benefits can be selected, thereby reducing the cost of the entire catalyst module.
