Description

Technical Field

[0001] The invention relates to the technical field of catalyst modules, in particular to an SCR catalyst module with adjustable installation angle. Background Art

[0002] The SCR catalyst module is a device that integrates catalyst units. These catalyst units can promote the chemical reaction between nitrogen oxides and reducing agents, thereby achieving the denitrification effect. In the SCR system, the catalyst module is the core component, which is responsible for providing the catalytic surface required for the reaction, so that nitrogen oxides and reducing agents can undergo efficient catalytic reduction reaction at a lower temperature.

[0003] When in use, most existing catalyst modules are a box-shaped structure with a catalytic unit arranged inside. When in use, they are installed and placed in the flue so that when the flue gas flows in the flue, the flue gas passing through the catalyst module contacts and reacts with the catalyst in the module. However, the catalytic components in the catalyst module are mostly fixedly installed, and the flue gas flows vertically to the end face of the catalyst. The angle during installation cannot be adjusted, which limits the effective contact between the flue gas and the catalytic component, increases the resistance of the catalyst layer, and reduces the rate and conversion rate of the catalytic reaction.

[0004] Therefore, an SCR catalyst module with adjustable installation angle is proposed to solve the above problems. Summary of the invention

[0005] In view of this, the technical problem to be solved by the present invention is to propose an SCR catalyst module with adjustable installation angle to solve the problem that the catalyst member in the catalyst module in the prior art cannot be flexibly adjusted.

A reset spring is equidistantly fixedly connected between the linkage rod and the mounting groove, and one end of the fixing screw located in the mounting groove is in contact with one side of the linkage rod.

[0011] One end of the L-shaped rod is fixedly connected to a positioning slider, and one side of the mounting frame is provided with a positioning groove, the positioning slider is slidably connected to the positioning groove, the bottom of the linkage rod is fixedly connected to an L-shaped slide, one side of the L-shaped slide is symmetrically rotatably connected to a connecting piece, both sides of the inner wall of the positioning slider are penetrated by limited position blocks that are slidably connected, and the connecting pieces are rotatably connected to adjacent limited position blocks.

[0012] One side of the L-shaped rod passes through a slidably connected limiting column, a compression spring is fixedly connected between the limiting column and the L-shaped rod, and limiting grooves are arranged on both sides of the inner wall of the installation frame.

[0013] The top end of the limiting column is set to be semicircular, the positioning groove is set to be cross-shaped, the limiting block is inserted into the positioning groove by sliding, and the limiting column is inserted into the limiting groove by sliding.

[0014] The adjusting sealing mechanism includes a transverse column, which is fixedly connected to one side of the linkage rod, and the transverse column is slidably connected to the mounting vertical plate. A fixed block is symmetrically slidably connected to one side of the mounting vertical plate, and a guide block is fixedly connected to the side of the fixed block close to the mounting vertical plate. The guide block is slidably connected to the mounting vertical plate, and a triangular groove is provided on the top of the guide block, and the transverse column is in contact with the inclined surface of the triangular groove.

[0015] A tension spring is fixedly connected between the fixing block and the mounting vertical plate, a resisting rod is fixedly connected to one side of the fixing block, and a fixing plate is symmetrically fixedly connected to one side of the mounting vertical plate.

[0017] A support spring is fixedly connected between the installation rod and the support frame, and a sealing strip is fixedly connected to one side of the installation rod away from the support spring, and the sealing strip is arranged in a Y shape.

[0018] Compared with the prior art, the present invention provides an SCR catalyst module with adjustable installation angle, which has the following beneficial effects:

[0019] 1. By sliding the adjustment block, the support frame can be adjusted under the action of the adjustment connecting rod. After the adjustment, the inclined catalyst body increases the contact area with the flue gas, and can also adapt to the direction of different flue gas flows, thereby improving the efficiency of the catalytic reaction. After the adjustment is completed, the limit block can be inserted into the positioning groove by rotating the fixing screw once, and the limit column can be inserted into the limiting groove, so that the adjusted catalyst body is more stable. At the same time, through the setting of the positioning slider and the limit block, when in use, it forms a cross through mechanical movement, and the cross-shaped positioning slider and the limit block can be combined with the cross-shaped The positioning grooves fit together, so that when the adjusted catalyst body is subjected to an external force of up and down vibration, the two cross-shaped fits can prevent the installation vertical plate from shaking up and down. At the same time, the limiting column is inserted into the limiting groove, so that when the adjusted catalyst body is subjected to an external force of front and back vibration, the limiting column and the limiting groove are plugged in and fit with the cross-shaped positioning slider and the limiting block, so that the installation vertical plate can be prevented from shaking back and forth. As a result, the adjusted catalyst body can be subjected to multi-directional vibrations and can maintain a relatively stable state, thereby improving the stability of the installation vertical plate after installation, thereby improving the accuracy of the catalyst body after adjustment.

[0020] In addition, by adjusting the angle of the catalyst body, when the adjustment angle becomes larger, the cross-sectional length of the mounting plate and the catalyst body increases, so a smaller number of mounting plates and catalyst bodies are placed in the mounting frame, and when the adjustment angle of the catalyst body becomes smaller, the cross-sectional length of the mounting plate and the catalyst body becomes smaller, so more mounting plates and catalyst bodies can be placed in the mounting frame, so that when the subsequent mounting frame needs to be placed in a flue with a higher flue gas pressure, more catalyst bodies can be installed to ensure the efficiency of flue gas catalysis, and when it needs to be placed in a flue with a lower flue gas pressure, fewer catalyst bodies can be installed, thereby saving the use cost of the catalyst body.

[0021] 2. By setting the positioning slider and the limit stopper, the positioning of the mounting plate can be achieved by plugging the positioning slider into the positioning groove during installation. At the same time, after the angle of the catalyst body is adjusted, the positioning slider and the limit stopper are continued to move to form a cross shape, and the formed cross shape is fitted with the cross-shaped positioning groove. When subjected to external force vibration, it can not only reduce the vibration influence in multiple directions and avoid shaking of the mounting plate, but also the cross-shaped fitting design can disperse the stress to multiple points, thereby reducing the risk of single-point damage.

[0022] 3. By setting the sliding of the mounting rod and the sealing strip, the sealing strip does not contact the inner wall of the mounting frame during adjustment, which can reduce the friction when the support frame rotates, reduce wear, and improve the smoothness of adjustment. At the same time, after the adjustment is completed, during the process of fixing the mounting vertical plate, the sealing strip is fitted with the inner wall of the mounting frame with the cooperation of the horizontal column and the triangular groove, thereby improving the sealing of the catalyst body and the support frame after the angle adjustment is completed. In addition, through the Y-shaped design of the sealing strip, when the sealing strip abuts against the inner wall of the mounting frame, the reaction force of the inner wall of the mounting frame can cause the sealing strip to undergo elastic deformation, so that the Y-shaped sealing strip becomes a T-shaped one. In this process, the two ends of the lower part of the sealing strip move in opposite directions. During the movement, the arc-shaped ends of the sealing strip can push the impurity particles on the inner wall of the mounting frame outward to prevent the impurity particles from affecting the sealing of the sealing strip, thereby improving the sealing effect of the support frame and the catalyst body when in use.

[0023] 4. By adjusting the coordination of the stabilizing mechanism and the sealing mechanism, after the angle adjustment of the catalyst body is completed, the catalyst body and the mounting plate can be fixed by rotating the fixing screw at the same time. At the same time, through the design of the cross column, the fixing block, the guide block and the triangular groove, the sealing work of the support frame after adjustment can be completed. Two fixing operations and one sealing work are completed in one rotation, which saves additional operating steps, so that the installation and fixing work of the catalyst body, the angle adjustment and fixing work and the sealing work after adjustment are completed simultaneously, which greatly saves the installation and adjustment time of the catalyst body and improves the installation and adjustment efficiency of the catalyst body.

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention.

[0041] In order to solve the problems mentioned in the technical solution, the embodiment of the present application provides an SCR catalyst module with adjustable installation angle, including an installation frame 1, and also including: an adjustment and stabilization mechanism and an adjustment and sealing mechanism, wherein the adjustment and sealing mechanism is driven by the adjustment and stabilization mechanism;

[0042] The adjusting and stabilizing mechanism includes a catalyst body 202, the adjusting and stabilizing mechanism is used to adjust the placement angle of the catalyst body 202, and the adjusting and sealing mechanism is used to seal the adjusting and stabilizing mechanism;

[0043] The catalyst body 202 is composed of catalyst units assembled together. The catalyst units can be implemented in a corrugated or honeycomb type. The catalyst units are supported and sealed by metal parts. The external dimensions and pore dimensions of the catalyst units can be freely adjusted.

[0044] The adjustment and stabilization mechanism also includes a mounting plate 201, which is arranged at the bottom of the inner wall of the mounting frame 1, and the mounting plate 201 located in the middle of the mounting frame 1 can be fixedly plugged into the outer wall of the mounting plate 201 to further improve the catalytic efficiency. One side of the mounting plate 201 is rotatably connected to a support frame 206, and the catalytic body 202 is fixedly connected between the inner walls of the support frame 206. One side of the mounting plate 201 is symmetrically provided with a slide groove 203, and each slide groove 203 is slidably connected to an adjustment block 204, and each adjustment block 204 is rotatably connected to an adjustment block 204 on one side. Connecting rod 205, one end of the adjusting connecting rod 205 is rotatably connected to the supporting frame 206; an L-shaped rod 2011 is symmetrically fixedly connected to one side of the mounting plate 201, and a fixing screw 207 is threadedly connected to one side of the adjusting block 204. Mounting grooves 208 are provided in the mounting plate 201 and the L-shaped rod 2011, and the fixing screw 207 is slidably connected to the sliding groove 203. A linkage rod 209 is slidably connected in the mounting groove 208, and a reset spring 210 is equidistantly fixedly connected between the linkage rod 209 and the mounting groove 208, and one end of the fixing screw 207 located in the mounting groove 208 is in contact with one side of the linkage rod 209.

[0045] One end of the L-shaped rod 2011 is fixedly connected to a positioning slider 211, and a positioning groove 212 is provided on one side of the installation frame 1. The positioning slider 211 is slidably connected to the positioning groove 212. An L-shaped slide 213 is fixedly connected to the bottom of the linkage rod 209, and a connecting piece 214 is symmetrically rotatably connected to one side of the L-shaped slide 213. Both sides of the inner wall of the positioning slider 211 pass through slidingly connected limited position blocks 215, and the connecting pieces 214 are rotatably connected to adjacent limited position blocks 215. One side of the L-shaped rod 2011 passes through a slidingly connected limited position column 216, and a compression spring 217 is fixedly connected between the limited position column 216 and the L-shaped rod 2011. Both sides of the inner wall of the installation frame 1 are provided with limited position grooves 218, the top of the limited position column 216 is set as a semicircle, and the positioning groove 212 is set as a cross. The limited position block 215 is inserted into the positioning groove 212 by sliding, and the limited position column 216 is inserted into the limited groove 218 by sliding.

[0046] Among them: when the mounting uprights 201 are placed, one side of the first mounting upright 201 is close to one side of the inner wall of the mounting frame 1, and the remaining mounting uprights 201 are constantly close to one side of the support frame 206, so that they are arranged equidistantly inside the mounting frame 1, and by adjusting the angle of the catalyst body 202, different numbers of catalyst bodies 202 can be placed in the mounting frame 1, when the adjustment angle of the catalyst body 202 becomes larger, the cross-sectional length of the mounting uprights 201 and the catalyst body 202 increases, so a smaller number of mounting uprights 201 and catalyst bodies 202 are placed in the mounting frame 1, when the adjustment angle of the catalyst body 202 becomes smaller, the cross-sectional length of the mounting uprights 201 and the catalyst body 202 becomes smaller, so more mounting uprights 201 and catalyst bodies 202 can be placed in the mounting frame 1, and after the adjustment is completed, when there is a gap between the last support frame 206 and one side of the inner wall of the mounting frame 1, the gap can be filled by installing an external filling plate.

[0047] In the prior art, the catalytic components in the catalyst module are mostly fixedly installed, and the angle during installation cannot be adjusted, which limits the effective contact between the flue gas and the catalytic component, and reduces the rate and conversion rate of the catalytic reaction. Compared with the prior art, in the implementation of this embodiment, the inclined catalytic component body 202 can increase the contact area with the flue gas, thereby improving the efficiency of the catalytic reaction, making the adjusted catalytic component body 202 more stable, improving the stability during use, and improving the accuracy of the adjusted catalytic component body 202.

[0048] For further examples, please refer to Figures 1 to 10 As shown:

[0049] The regulating sealing mechanism includes a horizontal column 301, which is fixedly connected to one side of the linkage rod 209, and the horizontal column 301 is slidably connected to the mounting plate 201. A fixed block 302 is symmetrically slidably connected to one side of the mounting plate 201, and a guide block 303 is fixedly connected to the side of the fixing block 302 close to the mounting plate 201. The guide block 303 is slidably connected to the mounting plate 201, and a triangular groove 304 is provided on the top of the guide block 303. The horizontal column 301 contacts the inclined surface of the triangular groove 304, and the fixing screw When 207 drives the linkage rod 209 to slide in the direction away from the adjustment block 204, it can drive the horizontal column 301 to slide at the same time. The horizontal column 301 pushes the inclined surface of the triangular groove 304, so that the guide block 303 drives the fixed block 302 to slide in the direction of the fixed plate 306. A tension spring 308 is fixedly connected between the fixed block 302 and the mounting vertical plate 201. A support rod 305 is fixedly connected to one side of the fixed block 302. A fixed plate 306 is symmetrically fixedly connected to one side of the mounting vertical plate 201. The lower two sides are slidably plugged with mounting rods 309, and one side of the mounting rods 309 is fixedly connected with an arc piece 307, which is movably connected to the fixed plate 306. The fixed plate 306 is also set to be arc-shaped, and an arc groove is set at the bottom of the fixed plate 306. The arc piece 307 slides along the arc groove when rotating, thereby improving the stability of the arc piece 307 when making an arc movement. At the same time, when the arc piece 307 is pressed down by the rod 305, the arc piece 307 can slide downward in the arc groove, and one of the arc pieces 307 A scale groove is provided on the top, the arc-shaped piece 307 is arc-shaped, and a scale groove is provided on the top of the arc-shaped piece 307 located at the bottom. When the staff adjusts the angle of the support frame 206 and the catalyst body 202, the scale groove penetrating the arc-shaped piece 307 can be used to improve the accuracy of adjustment. A support spring 311 is fixedly connected between the mounting rod 309 and the support frame 206, and a sealing strip 310 is fixedly connected to the side of the mounting rod 309 away from the support spring 311, and the sealing strip 310 is set in a Y shape.

[0050] Wherein: the sealing strip 310 is made of rubber material and has good elasticity. Through its Y-shaped design, when the sealing strip 310 abuts against the inner wall of the installation frame 1, the reaction force of the inner wall of the installation frame 1 can cause the sealing strip 310 to undergo elastic deformation, so that the Y-shaped sealing strip 310 becomes a T-shape.

[0051] Compared with the prior art, the implementation of this embodiment does not contact the inner wall of the installation frame 1 during adjustment, which can reduce the friction when the support frame 206 rotates, reduce wear, and improve the smoothness of adjustment. At the same time, after the adjustment is completed, during the process of fixing the mounting plate 201, with the cooperation of the cross column 301 and the triangular groove 304, the sealing strip 310 is fitted with the inner wall of the installation frame 1, thereby improving the sealing of the catalyst body 202 and the support frame 206 after the angle adjustment is completed.

[0052] Everything in the above example works like this:

[0053] In the initial state: the return spring 210 is in a normal state, the limit stop block 215 is located in the positioning slider 211, the linkage rod 209 is away from the top of the limit column 216, and when the compression spring 217 is in a normal state, the semicircular end of the top of the limit column 216 is located on the sliding track of the linkage rod 209.

[0054] The following is the working process of adjusting the placement angle of the catalyst body 202 by adjusting the stabilizing mechanism:

[0055] When in use, the mounting stand 201 is placed at the bottom of the inner wall of the mounting frame 1. When placed, it slides from front to back so that the positioning slide block 211 is inserted into the positioning groove 212, and then the adjusting block 204 is slid according to the demand. When the adjusting block 204 slides, the adjusting connecting rod 205 is driven to swing, and the swing of the adjusting connecting rod 205 drives the supporting frame 206 to rotate, so that the supporting frame 206 drives the catalyst body 202 to rotate to a proper angle, and the adjusting block 204 stops sliding, and the fixing screw 207 is manually rotated. Since the fixing screw 207 is threadedly connected with the adjusting block 204, the fixing screw 207 is screwed to the adjusting block 204. Rod 207 is in contact with linkage rod 209, so by rotating fixed screw 207, linkage rod 209 can be driven to slide in the direction away from adjustment block 204, reset spring 210 is compressed, linkage rod 209 slides and drives L-shaped slide 213 to slide, so that L-shaped slide 213 pushes connecting piece 214, connecting piece 214 rotates and pushes limit stop block 215 to slide outside positioning slide block 211, limit stop block 215 slides through positioning slide block 211 and is inserted into positioning groove 212, so that the two limit stop blocks 215 are away from each other and abut against the upper and lower sides of positioning groove 212.

[0056] Furthermore, when the linkage rod 209 slides in the direction away from the adjustment block 204, the bottom of the linkage rod 209 approaches the top of the limiting column 216 at the same time. Since the top of the limiting column 216 is set in a semicircular shape, when the linkage rod 209 approaches the limiting column 216, it will squeeze the semicircular top of the limiting column 216, thereby pushing the limiting column 216 to slide downward, the compression spring 217 is compressed, and the limiting column 216 slides downward and inserts into the limiting groove 218. At this time, the rotation of the fixing screw 207 can be stopped, and the positioning slide block 211 and the limiting stop block 215 passing through the positioning slide block 211 form a cross shape identical to the positioning groove 212. The cross shape formed by the positioning slider 211 and the limiting abutment 215 passing through the positioning slider 211 fits the inner wall of the positioning groove 212, and the linkage rod 209 is located above the limiting column 216. Under the limitation of the linkage rod 209, the limiting column 216 is inserted into the limiting groove 218 and no longer moves. At the same time, the pressure generated by the rebound of the reset spring 210 makes the linkage rod 209 and the fixing screw 207 tightly abut together, thereby increasing the friction between the linkage rod 209 and the fixing screw 207, thereby increasing the friction when the adjustment block 204 slides, thereby ensuring the fixing effect of the catalyst body 202 after adjustment.

[0057] By sliding the adjusting block 204, the support frame 206 can be adjusted under the action of the adjusting connecting rod 205. After the adjustment is completed, the limiting block 215 can be inserted into the positioning groove 212 and the limiting column 216 can be inserted into the limiting groove 218 by rotating the fixing screw 207 once, so that the adjusted catalyst body 202 is more stable and the stability during use is improved. At the same time, by setting the positioning slider 211 and the limiting block 215, when in use, a cross is formed through mechanical movement, and the cross-shaped positioning The positioning slider 211 and the limiting block 215 can fit with the cross-shaped positioning groove 212, so that when the adjusted catalyst body 202 is subjected to an external force of up and down vibration, the two cross-shaped fits can prevent the installation vertical plate 201 from shaking up and down. At the same time, the limiting column 216 is inserted into the limiting groove 218, so that when the adjusted catalyst body 202 is subjected to an external force of forward and backward vibration, the limiting column 216 and the limiting groove 218 are plugged and fit with the cross-shaped positioning slider 211 and the limiting block 215. , which can avoid the front and back shaking of the mounting plate 201, so that the catalyst body 202 after adjustment is subjected to multi-directional vibrations and can maintain a relatively stable state, thereby improving the stability of the mounting plate 201 after installation, thereby improving the adjustment accuracy of the catalyst body 202. At the same time, by adjusting the angle of the catalyst body 202, when the adjustable angle becomes larger, the cross-sectional length of the mounting plate 201 and the catalyst body 202 increases. Therefore, a small number of mounting plates 201 and catalyst bodies 202 are placed in the mounting frame 1. When the catalyst body 202 is When the adjustment angle of the component body 202 becomes smaller, the cross-sectional length of the mounting plate 201 and the catalytic component body 202 becomes smaller. Therefore, more mounting plates 201 and catalytic component bodies 202 can be placed in the mounting frame 1. When the subsequent mounting frame 1 needs to be placed in a flue with a higher flue gas pressure, more catalytic component bodies 202 can be installed to ensure the efficiency of flue gas catalysis. When it needs to be placed in a flue with a lower flue gas pressure, fewer catalytic component bodies 202 can be installed, thereby saving the use cost of the catalytic component bodies 202.

[0058] In addition, by providing the positioning slider 211 and the limiting stopper 215, the mounting plate 201 can be positioned by plugging the positioning slider 211 into the positioning groove 212 during installation. After the catalyst body 202 is adjusted in angle, the positioning slider 211 and the limiting stopper 215 are continued to move to form a cross shape, and the formed cross shape fits with the cross-shaped positioning groove 212. When subjected to external vibration, it can not only reduce the vibration influence in multiple directions and avoid shaking of the mounting plate 201, but also the cross-shaped fitting design can disperse the stress to multiple points, thereby reducing the risk of single-point damage.

[0059] When disassembly is required, the fixing screw 207 can be rotated in the opposite direction, and with the cooperation of the reset spring 210, the linkage rod 209 and the compression spring 217, the limiting stop block 215 is disengaged from the positioning groove 212, the limiting column 216 is disengaged from the limiting groove 218, so that the mounting plate 201 can be disassembled, which is simple and convenient. It should be noted that when the mounting plate 201 is placed, one side of the first mounting plate 201 is close to one side of the inner wall of the mounting frame 1, and the remaining mounting plates 201 are constantly close to one side of the support frame 206, so that they are equidistantly arranged inside the mounting frame 1. When one of the catalyst body 202 is damaged, the damaged catalyst body 202 can be disassembled and replaced alone, which will not affect the use of other catalyst body 202.

[0060] Please refer to the above working process Figures 1 to 10 .

[0061] The following is the working process of the adjusting sealing mechanism to the adjusting and stabilizing mechanism seal:

[0062] Furthermore, when the adjustment and stabilization mechanism is in use, the rotation of the support frame 206 can simultaneously drive the arc piece 307 to make an arc movement. Since the arc piece 307 is arc-shaped and a scale groove is provided on the top of the arc piece 307 located below, when the staff adjusts the angle of the support frame 206 and the catalyst body 202, the scale groove that runs through the arc piece 307 can be used to improve the accuracy of the adjustment. After the adjustment is completed, when the fixed screw 207 is rotated to drive the linkage rod 209 to slide in a direction away from the adjustment block 204, the cross column 301 can be driven to slide at the same time, and the cross column 301 pushes the inclined surface of the triangular groove 304, so that the guide The block 303 drives the fixed block 302 to slide in the direction close to the fixed plate 306, the tension spring 308 is stretched, and the fixed block 302 slides in the direction of the fixed plate 306, driving the push rod 305 to move at the same time, so that the end of the push rod 305 close to the arc piece 307 pushes the arc piece 307 to move toward the inner wall of the installation frame 1, and then drives the installation rod 309 to slide through the arc piece 307, and the support spring 311 is compressed. When the installation rod 309 slides, the sealing strip 310 abuts against the inner wall of the installation frame 1, and the gaps on the upper and lower sides of the support frame 206 are sealed, thereby improving the sealing performance of the support frame 206 after adjustment.

[0063] By the sliding arrangement of the mounting rod 309 and the sealing strip 310, the sealing strip 310 does not contact the inner wall of the mounting frame 1 during adjustment, which can reduce the friction force when the support frame 206 rotates. At the same time, after the adjustment is completed, in the process of fixing the mounting vertical plate 201, the sealing strip 310 is fitted with the inner wall of the mounting frame 1 under the cooperation of the cross column 301 and the triangular groove 304, thereby improving the sealing performance of the catalyst body 202 and the support frame 206 after the angle adjustment is completed. In addition, the Y-shaped design of the sealing strip 310 makes it possible for the sealing strip 310 to abut against the inner wall of the mounting frame 1 due to the reaction force of the inner wall of the mounting frame 1. The sealing strip 310 is elastically deformed, so that the Y-shaped sealing strip 310 becomes T-shaped. In this process, the two ends of the lower part of the sealing strip 310 move in opposite directions. When moving, the arc-shaped ends of the sealing strip 310 can push the foreign particles on the inner wall of the mounting frame 1 outward to prevent the foreign particles from affecting the sealing performance of the sealing strip 310, thereby improving the sealing effect of the support frame 206 and the catalyst body 202 when in use. In addition, when it is necessary to disassemble the mounting plate 201, the fixing block 302 and the sealing strip 310 can be driven to reset under the action of the tension spring 308 and the support spring 311, which is convenient for the next use.
