Description

Technical Field

[0001] This invention relates to the field of catalyst support detection technology, and in particular to a catalyst support detection device. Background Technology

[0002] In the environmental protection field, especially in the treatment of industrial flue gas, SCR (Selective Catalytic Reduction) technology is widely used in denitrification processes, and corrugated plate SCR catalysts are one of the core components. Their performance directly affects the removal efficiency of nitrogen oxides (NOx), system operating costs, and environmental compliance. Therefore, monitoring the corrugated plate SCR catalyst is crucial. For example, to ensure denitrification efficiency and environmental compliance, activity decay is often monitored. When SCR catalysts are exposed to high temperatures (300-400℃), high dust levels, sulfur-containing (SO2 / SO3), and heavy metals (such as As and Pb) in flue gas for extended periods, the active components (such as V2O5-WO3 / TiO2) can become deactivated due to poisoning, sintering, or blockage. Regular testing can assess the remaining catalyst activity and prevent NOx emissions from exceeding limits due to efficiency decline. At the same time, the structural integrity is tested. The multi-layered corrugated structure of the corrugated plate catalyst is prone to cracks and collapse due to mechanical stress or uneven thermal expansion. Testing can detect physical damage in time and prevent local airflow short circuits from causing a sharp drop in denitrification efficiency.

[0003] Chinese Patent Publication No. CN213068630U discloses a honeycomb-type carrier catalyst detection device, characterized by comprising a support and a light source box. The light source box is mounted on the support and contains a detection unit and a drying unit. The detection unit includes a light source, a lens, and a support plate. The light source is fixed at the bottom of the light source box. The lens converts the light source light into a substantially straight beam. The support plate is located above the lens and is made of transparent glass. The support plate contains an air flow channel with an upward-facing air outlet. The drying unit includes a box body, an axial flow motor, and fan blades. The box body is mounted on the light source box and has an air inlet and an air outlet. The air inlet is connected to an air inlet on the light source box. The axial flow motor is mounted inside the box body, and the air outlet of the box body is connected to the air inlet of the air flow channel via a pipe. Therefore, the honeycomb-type carrier catalyst detection device has the following problems:

[0004] The light source cannot be moved according to the location of the carrier or the actual situation, and cannot fully irradiate the catalyst carrier. Insufficient irradiation range affects the detection accuracy. Summary of the Invention

[0005] Therefore, the present invention provides a catalyst support detection device to overcome the problems in the prior art where the light source cannot be moved according to the position or actual situation of the support, thus failing to fully irradiate the catalyst support and resulting in insufficient irradiation range affecting the detection accuracy.

[0006] To achieve the above objectives, the present invention provides a catalyst support detection device, comprising:

[0007] A support frame, wherein a plurality of support components are arranged sequentially from top to bottom within the support frame;

[0008] An image detection component, located at the top of the support frame, is used to acquire upper and lower projected images of the catalyst carrier located in the middle of the support frame within an enclosed space. The image detection component includes a camera device, a supplementary lighting device, and an adjustment device. The camera device is suspended from the top of the support frame via the adjustment device, which can adjust the height and tilt angle of the camera device and control its four-way lateral movement.

[0009] A carrier receiving component, located in the middle of the carrier frame, is used to measure the weight of the catalyst carrier and limit the relative position of the catalyst carrier and the image detection component;

[0010] The projection assembly includes a light source device and a projection carrier. The light source device is located at the bottom of the carrier receiving assembly and is used to penetrate and irradiate the interior of the catalyst carrier. The projection carrier is located at the bottom of the image detection assembly and is used to receive and form a lower projection image of the interior of the catalyst carrier.

[0011] Furthermore, the imaging device is an industrial camera, the adjustment device is a sheet metal bracket, and the supplementary lighting device is a strip-shaped supplementary light, used to provide a light source in an enclosed space to supplement the image of the upper part of the carrier acquired by the industrial camera.

[0012] Furthermore, the sheet metal bracket includes a hanging plate and a side plate. The hanging plate has several hanging holes for suspending the sheet metal bracket on the top of the support frame. The side plate has several side holes in the vertical direction for suspending the industrial camera so that it can slide up and down and adjust its angle.

[0013] Furthermore, the projection carrier is a glass panel, which is disposed on the support assembly located at the top of the support frame and is used to support the lower projected image.

[0014] Furthermore, the carrier receiving component includes a glass base and a U-shaped scale. The glass base is located at the bottom of the catalyst carrier and is used to support the catalyst carrier and limit the relative positional relationship between the catalyst carrier and the U-shaped scale.

[0015] The U-shaped scale is fixedly connected to the inner side of the support assembly at the bottom of the support frame and is located at the bottom of the glass base, used to detect the weight of the catalyst carrier.

[0016] Furthermore, the light source device is a fixed device or a mobile device, and the fixed device includes a parallel light source;

[0017] The parallel light source is plate-shaped and located at the bottom of the U-shaped scale. It penetrates the catalyst carrier and projects onto the glass panel to form a lower projection image.

[0018] Furthermore, the mobile device includes a parallel light source and a moving component;

[0019] The movable component is disposed at the bottom of the parallel light source. The movable component includes a bracket, a first slide rail, and a second slide rail. The first slide rail and the second slide rail are mounted parallel to each other on the top two sides of the bracket.

[0020] The parallel light source is plate-shaped and located at the bottom of the U-shaped scale and at the top of the first and second slide rails of the moving component, and can slide on the first and second slide rails.

[0021] Furthermore, the detection device also includes an inspection door and a roller shutter door;

[0022] The support frame is provided with a roller shutter door on its side, and when the roller shutter door is lowered, it forms the enclosed space with the support frame.

[0023] The inspection door is located on the top of the roller shutter door and on the top side of the support frame, on the same side as the roller shutter door, and the inspection door is hinged to the support frame;

[0024] A display screen is embedded in the middle of the inspection door, and the display screen is used to display the detection information of the catalyst carrier.

[0025] Furthermore, the detection device is equipped with a moving mechanism at the four corners of its bottom, the moving mechanism consisting of a fuma wheel and a mounting base;

[0026] The mounting base is fixedly connected to the four bottom corners of the detection device, and the fuma wheel is located at the bottom of the mounting base and is rotatably connected to it.

[0027] Furthermore, the catalyst support detection device is also equipped with a pushing device, which includes:

[0028] A first base plate with a square frame structure is located at the bottom of the glass base; a second base plate is located at the bottom of the first base plate and is fixedly connected to the pushing device; four lifting rods are provided between the first base plate and the second base plate.

[0029] The pushing device also includes an operating rod for controlling the extension and retraction of the lifting rod, which can drive the first base plate to rise and fall by controlling the extension and retraction of the lifting rod.

[0030] Compared with existing technologies, the advantages of this invention are that this device can quickly detect physical indicators such as weight, size, and number of layers of the corrugated plate catalyst carrier before production, and can quickly screen out unqualified carriers, avoiding waste of resources in the next process. It also retains the physical information of qualified carriers, which helps to establish a full life-cycle quality management system. For finished catalysts, it can quickly detect the pore permeability of the corrugated plate catalyst, and identify unqualified products through algorithm evaluation. While catalyst carriers have advantages such as low pressure drop and high anti-clogging properties in SCR (Selective Catalytic Reduction) denitrification systems, in actual applications, the start-up and shutdown of the unit may cause distortion or cracks on the surface of the catalyst carrier. For used catalyst carriers, this device performs preliminary detection of the catalyst carrier's condition through an image of the upper part of the carrier, and proceeds to the next step of detection if the carrier is in good condition.

[0031] Furthermore, the structure of corrugated plate catalysts is susceptible to blockage by fly ash in the flue gas. After long-term operation, fly ash accumulates and cakes on the catalyst surface and within the corrugated channels, leading to a reduction in effective reaction area and a decrease in denitrification efficiency. Simultaneously, ammonium bisulfate (ABS) may also adhere to the catalyst surface in liquid form, exacerbating blockage. This device achieves in-depth non-destructive testing by acquiring lower projection images and analyzing the carrier permeability based on these images.

[0032] Furthermore, due to the diffuse reflection of fly ash and the scattering angle of the light source, the actual ash accumulation at the edge of the catalyst support may be misjudged as normal (insufficient illumination masks grayscale changes), and slight discoloration in the central area may be magnified as a serious defect. This device uses the horizontal movement of the bottom parallel light source for dynamic optical reconstruction and utilizes multi-angle projection difference analysis to determine the three-dimensional transparency characteristics of the catalyst support. This significantly improves the accuracy and depth information acquisition capability of traditional static detection, avoiding the detection error risk caused by illumination attenuation at the edge. Simultaneously, this device can complete the detection of the catalyst support's weight (error ±100g), length and width dimensions (±1mm), number of corrugated layers (error ±1 layer), and pore transparency within a 2-minute detection cycle. In existing technologies, except for the pore transparency parameter, the overall detection speed is approximately 5 minutes, and the pore transparency parameter cannot be manually detected.

[0045] This invention provides a catalyst support detection device, comprising:

[0046] A support frame, wherein a plurality of support components are arranged sequentially from top to bottom within the support frame;

[0047] An image detection component, located at the top of the support frame, is used to acquire upper and lower projected images of the catalyst carrier located in the middle of the support frame within an enclosed space. The image detection component includes a camera device, a supplementary lighting device, and an adjustment device. The camera device is suspended from the top of the support frame via the adjustment device, which can adjust the height and tilt angle of the camera device and control its four-way lateral movement.

[0048] A carrier receiving component, located in the middle of the carrier frame, is used to measure the weight of the catalyst carrier and limit the relative position of the catalyst carrier and the image detection component;

[0049] The projection assembly includes a light source device and a projection carrier. The light source device is located at the bottom of the carrier receiving assembly and is used to penetrate and irradiate the interior of the catalyst carrier. The projection carrier is located at the bottom of the image detection assembly and is used to receive and form a lower projection image of the interior of the catalyst carrier.

[0050] In this embodiment,

[0051] The support frame has several supporting components 9 inside. From top to bottom, the support frame has a top plate 8, a sheet metal bracket 61, an industrial camera 6, a fill light 7, a glass panel (not shown), a catalyst carrier 21, a glass base 11, a U-shaped scale 3, a parallel light source 4, and a moving component.

[0052] Specifically, the catalyst carrier testing device is an 800mm*800mm*1855mm painted stainless steel square box. A 15.6-inch display screen is mounted on the upper front of the box. Inside, at the top, is a 20-megapixel industrial camera with an 8mm fixed-focus lens, adjustable at multiple angles. The camera lens has a centered, vertically downward viewing angle. A compact computer, power supply, and control circuit board are also included. Inside the box, strip-shaped supplementary lights are installed on the upper three-quarters of the sides, providing downward illumination at a 45° angle. A semi-transparent glass panel (removable) is placed in the center. A U-shaped scale is located at the bottom, below which is a 550*550 parallel light source, vertically upward, for penetrating illumination of the catalyst carrier. An opening is provided at the bottom front of the box for the catalyst carrier to be tested to enter and exit. After the catalyst carrier is placed, the flexible electric roller shutter door closes, creating a sealed, light-proof environment. All parts are fixedly connected to the metal box with bolts and brackets through drilled holes.

[0053] The industrial camera 6 is suspended from the bottom of the top plate 8 by a sheet metal bracket 61, and is used to acquire the upper image and lower projection image of the catalyst carrier 2. The sheet metal bracket 61 can adjust the height and lens tilt angle of the vision camera 6 and control its four-way horizontal movement.

[0054] The sheet metal bracket includes a hanging plate 612 and a side plate 613. The hanging plate is provided with a plurality of hanging holes 611 for suspending the sheet metal bracket 61 on the top of the support frame. The side plate is provided with a plurality of side holes 614 in the vertical direction. The side holes 614 are used to suspend the industrial camera 6 so that it can slide up and down and adjust the angle.

[0055] Specifically, the sheet metal bracket 61 is a multi-angle adjustable bracket that supports the camera to move horizontally in four directions (front, back, left, and right), supports the camera to move vertically by 100mm, and supports the camera lens to swing and tilt freely by 180°.

[0056] The glass panel is disposed on top of the support assembly 9 located at the top of the support frame, and is used to support the lower projected image;

[0057] The glass base 11 is located at the bottom of the catalyst carrier 2 and is used to support the catalyst carrier 2 and limit the relative positional relationship between the catalyst carrier 2 and the U-shaped scale 3.

[0058] The U-shaped scale 3 is fixedly connected to the inner side of the support component 9 at the bottom of the support frame and is located at the bottom of the glass base 11, and is used to detect the weight of the catalyst carrier 2.

[0059] The side of the support frame is provided with a roller shutter door 5, which forms a closed space with the support frame when it is lowered.

[0060] The parallel light source 5 is plate-shaped and located at the bottom of the U-shaped scale 4. The moving component is located at the bottom of the parallel light source 5. The moving component includes a bracket 41, a first slide rail 42 and a second slide rail 43. The first slide rail 42 and the second slide rail 43 are mounted parallel to each other on the top two sides of the bracket 41.

[0061] The industrial camera 6 has an adjustable lens angle, and the fill light 7 is a strip-shaped light source used to provide fill light to the industrial camera in a closed environment.

[0062] The detection device also includes an inspection door 101, which is located on the top of the roller shutter door 5 and the top side of the support frame, on the same side as the roller shutter door 5. The inspection door 101 is hinged to the support frame.

[0063] A display screen 102 is embedded in the middle of the inspection door 101. The display screen 102 is used to display the detection information of the catalyst carrier 2.

[0064] The detection device has a moving mechanism at the four corners of its bottom. The moving mechanism consists of a fuma wheel 17 and a mounting base 16. The mounting base 16 is fixedly connected to the four corners of the bottom of the detection device, and the fuma wheel 17 is located at the bottom of the mounting base 16 and is rotatably connected to it.

[0065] Specifically, the support frame has four sets of support components from top to bottom, which divide the support frame into five layers. The industrial camera, inspection door, and display screen are located on the fifth layer of the support frame. The fill light, roller shutter door, and glass panel are located on the fourth layer of the support frame. The catalyst carrier is located on the third and second layers of the support frame. The glass base and U-shaped scale are located on the second layer of the support frame. The parallel light source and the moving component are located on the first layer of the support frame.

[0066] Specifically, this device can quickly detect physical indicators such as weight, size, and number of layers of the corrugated plate catalyst support before production, rapidly screening out unqualified supports and preventing resource waste in subsequent processes. It also retains the physical information of qualified supports, contributing to the establishment of a full life-cycle quality management system. For finished catalysts, it can quickly detect the pore permeability of the corrugated plate catalyst and, through algorithm evaluation, identify unqualified products. While catalyst supports offer advantages such as low pressure drop and high anti-clogging properties in SCR (Selective Catalytic Reduction) denitrification systems, in practical applications, unit start-ups and shutdowns can cause surface distortion or cracking of the catalyst support. For used catalyst supports, this device performs preliminary inspection using images of the upper part of the support to determine its condition, proceeding to the next step of inspection if the support is in good condition.

[0067] The catalyst support detection device is further provided with a pushing device 1, which includes:

[0068] A first base plate 13 with a square frame structure is located at the bottom of the glass base. A second base plate 14 is located at the bottom of the first base plate 13 and is fixedly connected to the pushing device 1. Four lifting rods 15 are provided between the first base plate 13 and the second base plate 14. The first base plate 13 can be raised and lowered by extending and retracting the lifting rods 15. The pushing device 1 also includes an operating rod 12 for controlling the extension and retraction of the lifting rods.

[0069] In this embodiment, the physical parameters of the catalyst support are as follows:

[0070] It is a white cuboid, 465mm long, 465mm wide, and 500mm high. It has 120 layers (1 layer is wavy), weighs 30.2±2.5KG, and has triangular pores with a pore size of approximately 5mm.

[0071] Specifically, the structure of corrugated plate catalysts is susceptible to blockage by fly ash in the flue gas. After long-term operation, fly ash accumulates and cakes on the catalyst surface and within the corrugated channels, leading to a reduction in effective reaction area and a decrease in denitrification efficiency. Simultaneously, ammonium bisulfate (ABS) may also adhere to the catalyst surface in liquid form, exacerbating the blockage. This device achieves in-depth non-destructive testing by acquiring lower projection images and analyzing the carrier permeability based on these images.

[0072] Work process:

[0073] The catalyst carrier is placed on the base of the movable pusher device. The height of the first base plate is raised, and the pusher device is moved to push the catalyst carrier into the support frame box. The height of the first base plate of the pusher device is then lowered, and the carrier, along with the glass base, is supported by the U-shaped scale inside the box. The pusher device slides out, and the electric roller shutter door is lowered using a remote control. After the box is closed, the layer identification button on the box is pressed, and the strip-shaped supplementary light above illuminates for 1 second. Simultaneously, the industrial camera takes a picture according to the first exposure compensation preset parameters to acquire an image of the upper part of the carrier. The computer reads the reading of the U-shaped scale through the RS485 interface and displays the analyzed carrier size, number of layers, weight, and whether it is qualified, along with the upper part of the carrier image, on the 15.6-inch display screen of the box. The information is also recorded in the local database.

[0074] After the catalyst carrier passes the initial inspection, the electric roller shutter door is raised, a semi-transparent glass panel is placed, the electric roller shutter door is lowered, and the hole-blocking identification button on the chamber is pressed. The bottom parallel light source lights up for 5 seconds, the beam penetrates the carrier, and projects onto the semi-transparent glass panel. At the same time, the industrial camera takes a picture of the lower projection image according to the second exposure compensation preset parameters. The computer displays the analyzed carrier transparency and whether it is qualified, along with the lower projection image, on the 15.6-inch screen of the chamber.

[0075] Specifically, due to the diffuse reflection of fly ash and the scattering angle of the light source, the actual ash accumulation at the edge of the catalyst support may be misjudged as normal (insufficient illumination masks grayscale changes), and slight discoloration in the central area may be magnified as a serious defect. This device uses a horizontally moving bottom parallel light source for dynamic optical reconstruction and utilizes multi-angle projection difference analysis to determine the three-dimensional transparency characteristics of the catalyst support. This significantly improves the accuracy and depth information acquisition capability of traditional static detection, avoiding the detection error risk caused by illumination attenuation at the edge. Simultaneously, this device can complete the detection of the catalyst support's weight (error ±100g), length and width dimensions (±1mm), number of corrugated layers (error ±1 layer), and pore transparency within a 2-minute detection cycle. In existing technologies, except for the pore transparency parameter, the overall detection speed is approximately 5 minutes, and the pore transparency parameter cannot be manually detected.
