Description

Technical Field

[0001] The invention relates to the technical field of catalyst unit arrangement, and in particular to an angle-controllable SCR catalyst unit arrangement device. Background Art

[0002] The SCR catalyst module is a device that integrates catalyst materials. These catalyst materials 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. It 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, the catalyst module needs to be installed and placed in the flue or reactor. When placed, the installation angle of the catalyst module can be adjusted to make it better adapt to the flow field distribution in the flue or reactor, thereby improving the catalytic efficiency. However, after the existing catalyst modules complete the angle adjustment, most of them directly fix each catalyst module by bolts or welding, which makes it inconvenient to change the angle later and has poor flexibility. In order to flexibly adjust the angle of the catalyst module during installation, some catalyst modules will connect each catalyst module together by means of hinges. Because the hinges need to be fixed to the catalyst modules with bolts during installation, this method will cause inconvenience when each catalyst module is disassembled later, resulting in poor flexibility or inconvenient disassembly and maintenance of the existing catalyst modules when adjusting the angle.

[0018] Compared with the prior art, the present invention provides a controllable angle SCR catalyst unit arrangement device, which has the following beneficial effects:

[0019] 1. Through the cooperation of the angle adjustment mechanism and the fixed installation mechanism, the arrangement of the second ball and the annular groove, when the angle of the first catalyst body and the second catalyst body is adjusted, through the plug-in limit between the plug plate and the upper slot and the plug-in limit between the second ball and the annular groove, when the first catalyst body and the second catalyst body are subjected to the action of axial external force, the bottom of the upper insert tube and the top of the fixed bottom tube are always in contact with each other through the limit, and no axial movement occurs, thereby improving the stability of the upper insert tube and the fixed bottom tube when they rotate relative to each other, and through the rotation of the second ball, when the upper insert tube and the fixed insert tube rotate in the fixed bottom tube, the friction force of the fixed insert tube when it rotates in the fixed bottom tube can be reduced, thereby ensuring the upper The insert tube and the fixed insert tube rotate smoothly with the fixed bottom tube, and the first catalyst body and the second catalyst body are adjusted smoothly. Compared with the hinge connection in the prior art, on the basis of ensuring stability and smoothness, the pull block slides up and down, so that the linkage pull rod drives the conical push block to slide up and down, and with the cooperation of the reset spring, the second ball is inserted into or out of the connection with the annular groove. The operation can be completed without the help of tools, and the connection between the fixed insert tube and the fixed bottom tube can be easily completed. Not only can the installation angle of the first catalyst body and the second catalyst body be flexibly controlled, but also it is convenient to complete the disassembly and maintenance of the first catalyst body and the second catalyst body in the subsequent process.

[0020] 2. By setting the pressing and extruding mechanism, the lubricating liquid can be evenly attached between the fixed insert and the fixed base cylinder. By pressing the fixed insert and the fixed base cylinder during installation, the lubricating liquid can be evenly added between the fixed insert and the fixed base cylinder. Compared with manual spraying and spraying, it saves power resources while ensuring uniformity. At the same time, the lubricating liquid can be sprayed by squeezing the compression tube while inserting the fixed insert, so that installation and spraying can be carried out simultaneously, saving additional spraying steps and improving the uniformity of spraying the fixed insert and the fixed base cylinder. The concave and convex ring shape of the compression tube can make it easier to compress when under pressure. By setting the third ball, when the fixed insert and the fixed base cylinder rotate relative to each other, the friction between the bottom end of the fixed insert and the bottom end of the inner cavity of the fixed base cylinder can be reduced by rotating the compression tube, further improving the smoothness of the rotation of the fixed insert and the fixed base cylinder.

[0021] 3. Through the cooperation of the angle adjustment mechanism, the fixed installation mechanism and the pressing and extruding mechanism, the first catalyst body and the second catalyst body can be connected through the fixed lower cylinder, the upper insert cylinder and the fixed insert tube, and after the connection, the first catalyst body and the second catalyst body can be flexibly adjusted in angle, which not only ensures the stability and smoothness during adjustment, but also enables the first catalyst body and the second catalyst body to be disassembled or installed by only sliding the sliding plate up and down, avoiding the use of tools and complicated operations, improving the convenience of subsequent maintenance of the first catalyst body and the second catalyst body, and improving the efficiency of subsequent maintenance;

[0022] 4. By setting the sliding column to have a smaller diameter than the guide sleeve and one end of the guide sleeve being in an arc shape, when the sliding column is received in the fixed insert tube, the guide sleeve can support one end of the sliding column and receive the second ball, thereby guiding the movement trajectory of the sliding column and providing necessary storage and sliding space for the sliding column and the second ball. At the same time, the arc-shaped setting at one end of the guide sleeve can make the guide sleeve better fit the inner wall of the fixed insert tube, thereby enhancing the stability of the structure. By setting the tapered surface of the tapered push block, the linkage pull rod slides upward at one time, so that the tapered surface of the tapered push block can squeeze multiple first balls to slide outward at the same time, thereby simultaneously making multiple second balls enter the annular groove, ensuring that all first balls are simultaneously subjected to thrust and slide outward, thereby achieving multiple second balls synchronously entering the annular groove and fitting together, with high synchronization, preventing the second balls from being uneven in the annular groove, which not only improves the installation efficiency, but also improves the stability and accuracy during installation.

[0037] 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. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] The present invention is further described in detail below based on the accompanying drawings and embodiments.

[0039] Embodiments of the present invention: Please refer to Figures 1 to 9 As shown:

[0040] In order to solve the problems mentioned in the technical solution, the embodiment of the present application provides an angle controllable SCR catalyst unit arrangement device, including a reactor body 1, a first catalyst body 11 and a second catalyst body 12 are respectively arranged at the bottom of the inner wall of the reactor body 1, and also includes: an angle adjustment mechanism, a fixing installation mechanism and a pressing and extruding mechanism;

[0041] The angle adjustment mechanism is used to adjust the installation angle of the first catalyst body 11 and the second catalyst body 12 , the fixing and installation mechanism is used to fix the first catalyst body 11 and the second catalyst body 12 , and the pressing and extruding mechanism is used to extrude the lubricating liquid.

[0042] The first catalyst body 11 and the second catalyst body 12 are assembled from equidistantly arranged catalyst units. The catalyst units are implemented in a corrugated or honeycomb type.

[0043] The angle adjustment mechanism includes a fixed bottom cylinder 201, which is fixedly connected to the side of the first catalyst body 11 close to the second catalyst body 12, and the second catalyst body 12 is fixedly connected to the side of the first catalyst body 11 close to the first catalyst body 11. The first catalyst body 11 and the second catalyst body 12 are arranged at the same height, and the upper insert cylinder 202 and the fixed bottom cylinder 201 are arranged with the same diameter. The inner cavity of the fixed bottom cylinder 201 is symmetrically provided with an annular groove 203, and the bottom of the upper insert cylinder 202 is fixedly connected to a fixed insert tube 204, and the fixed insert tube 204 is plugged into the fixed bottom cylinder 201. A guide sleeve 205 is fixedly connected to the fixed insert tube 204, and a sliding column 200 is slidably connected to the guide sleeve 205. 6. The diameter of the sliding column 206 is smaller than that of the guide sleeve 205. The end of the guide sleeve 205 close to the fixed insert tube 204 is arc-shaped. The sliding column 206 is slidably connected to the fixed insert tube 204. A reset spring 207 is equidistantly fixedly connected between the guide sleeve 205 and the sliding column 206. One end of the sliding column 206 is rotatably connected to a first ball 208. The end of the sliding column 206 away from the first ball 208 is rotatably connected to a second ball 209. The second ball 209 can be inserted into the annular groove 203. A linkage rod 210 is slidably connected to the bottom of the upper insert tube 202. A conical push block 211 is symmetrically fixedly connected to the outer surface of the linkage rod 210. The conical surface of the conical push block 211 is in contact with the first ball 208.

[0044] The fixed installation mechanism includes a connecting column 301, which is fixedly connected to the top of the linkage pull rod 210, and a sliding disk 302 is fixedly connected to the top of the connecting column 301. The sliding disk 302 is slidably connected to the upper plug-in tube 202, and a pull block 303 is slidably inserted at the top of the sliding disk 302. The lower end of the pull block 303 is equidistantly connected to a connecting push-pull sheet 304, and an insert plate 305 is equidistantly penetrated and slidably connected to the outer surface of the sliding disk 302. The end of the insert plate 305 close to the connecting push-pull sheet 304 is rotatably connected to the connecting push-pull sheet 304, and the upper The inner cavity of the insert tube 202 is symmetrically fixed with a positioning block, the inner cavity of the upper insert tube 202 is provided with a slot 309, the insert plate 305 is plugged into the slot 309, one side of the insert plate 305 and one side of the slot 309 are both arranged in a zigzag shape, the bottom end of the pull block 303 is fixedly connected to a bottom column 307, the bottom of the inner wall of the sliding plate 302 is fixedly connected to a support column 306, the outer surface of the upper end of the support column 306 is equidistantly fixedly connected with a clamping block 308, the clamping block 308 is clamped with the bottom column 307, and a spring telescopic rod is arranged between the insert plate 305 and the support column 306.

[0045] Among them: through the setting of the first ball 208, when the conical push block 211 squeezes the first ball 208, the friction between the conical push block 211 and the first ball 208 can be reduced through the rolling of the first ball 208, thereby reducing the friction between the conical push block 211 and the first ball 208, thereby increasing its service life, and also improving the smoothness of the linkage rod 210 when pulling upwards, saving manpower.

[0046] In the prior art, after the existing catalyst modules complete the angle adjustment, most of them are directly fixed by bolts or welding, which makes it inconvenient to replace the angle later and has poor flexibility. In order to flexibly adjust the angle of the catalyst module during installation, some catalyst modules will connect the catalyst modules together by hinges. Because the hinges need to be fixed to the catalyst module by bolts during installation, this method will cause inconvenience when the catalyst modules are disassembled later, resulting in poor flexibility or inconvenient disassembly and maintenance of the existing catalyst modules when adjusting the angle. Compared with the prior art, the implementation of this embodiment ensures that the bottom of the upper insert cylinder 202 and the top of the fixed bottom cylinder 201 are always in contact with each other through limiting, and no axial movement occurs, thereby improving the stability of the upper insert cylinder 202 and the fixed bottom cylinder 201 during relative rotation, and through the rotation of the second ball 209, the upper When the insert tube 202 and the fixed insert tube 204 rotate in the fixed bottom tube 201, the friction force of the fixed insert tube 204 when rotating in the fixed bottom tube 201 can be reduced, thereby ensuring the smoothness of the upper insert tube 202 and the fixed insert tube 204 when rotating with the fixed bottom tube 201, and the smoothness of the angle adjustment of the first catalyst body 11 and the second catalyst body 12. On the basis of ensuring stability and smoothness, the linkage pull rod 210 drives the conical push block 211 to slide up and down by sliding the pull block 303 up and down, and with the cooperation of the return spring 207, the second ball 209 is inserted into or disengaged from the annular groove 203, and the operation can be completed without the aid of tools, thereby easily completing the plug-in of the fixed insert tube 204 and the fixed bottom tube 201, which can not only flexibly control the installation angle of the first catalyst body 11 and the second catalyst body 12, but also facilitate the subsequent disassembly and maintenance of the first catalyst body 11 and the second catalyst body 12.

[0047] For further examples, please refer to Figures 1 to 9 As shown:

[0048] The pressing and extruding mechanism includes a connecting tube 401, which is clamped at the bottom of the fixed insert tube 204. The lower end of the connecting tube 401 is fixedly connected to a compression tube 402. The outer surface of the compression tube 402 is arranged in a concave-convex ring shape. The bottom of the compression tube 402 is fixedly connected to a fixing seat. The bottom of the fixing seat is rotatably connected to a third ball 403. Liquid outlet holes 404 are equidistantly provided on the outer surface of the fixed insert tube 204. A connecting channel is provided on the fixed insert tube 204. The liquid outlet holes 404 are connected to the connecting tube 401 and the compression tube 402 through the connecting channel.

[0049] Wherein: the compression tube 402 is set to be made of rubber material, has good elasticity, and can be better compressed and rebounded by cooperating with its concave and convex ring.

[0050] In the prior art, lubricants are mostly sprayed manually or by machine during installation. Manual spraying is unstable and may result in waste or uneven spraying. In addition, machine spraying requires electricity. Compared with the prior art, the implementation of this embodiment ensures uniformity while saving the use of electricity resources. At the same time, the lubricant is sprayed by inserting the fixed insert 204 and squeezing the compression tube 402 at the same time, which saves additional spraying steps and improves the uniformity of spraying the fixed insert 204 and the fixed bottom cylinder 201. The concave and convex annular setting of the compression tube 402 makes it easier to compress when it is under pressure. Through the setting of the third ball 403, when the fixed insert 204 and the fixed bottom cylinder 201 rotate relative to each other, the friction between the bottom end of the fixed insert 204 and the bottom end of the inner cavity of the fixed bottom cylinder 201 can be reduced by rotating the compression tube 402, further improving the smoothness of the fixed insert 204 and the fixed bottom cylinder 201 when rotating.

[0051] Everything in the above example works like this:

[0052] In the initial state: when the return spring 207 is in a normal state, the sliding column 206 does not penetrate the fixed insert tube 204 and is received in the fixed insert tube 204, when the connecting column 301 does not slide upward, the plug plate 305 is plugged into the lower slot 309, and the top of the support column 306 is in contact with the bottom of the bottom column 307, the clamping block 308 is in a clamping state with the bottom column 307, and when the fixed insert tube 204 is not fully inserted into the fixed bottom cylinder 201, the compression tube 402 is in a normal state.

[0053] The following is a working process of the angle adjustment mechanism adjusting the installation angle of the first catalyst body 11 and the second catalyst body 12 and the fixing mechanism fixing the first catalyst body 11 and the second catalyst body 12:

[0054] When in use, first insert the fixed insert tube 204 on one side of the second catalyst body 12 into the fixed bottom cylinder 201 until the bottom of the upper insert tube 202 contacts the top of the fixed bottom cylinder 201, then pull the pull block 303 upward, the pull block 303 slides upward to drive the end of the connecting push-pull sheet 304 close to the pull block 303 to move upward, so that the end of the connecting push-pull sheet 304 close to the plug plate 305 pulls the plug plate 305 toward the center, the spring telescopic rod is compressed, the block 308 is disengaged from the bottom column 307, and the end of the plug plate 305 inserted into the slot 309 is disengaged. At this time, since the limit of the plug plate 305 and the slot 309 is released, the pull block 303 can continue to be pulled to make the sliding plate 302 slide upward until the top of the sliding plate 302 contacts the positioning block in the upper insertion tube 202, and then the pulling of the pull block 303 is stopped. At this time, under the rebound action of the spring telescopic rod, the pull block 303 is driven to slide into the sliding plate 302, and under the push of the connecting push-pull sheet 304, the plug plate 305 is inserted into the upper slot 309, and the clamping block 308 is re-engaged with the bottom column 307, thereby completing the fixation of the sliding plate 302.

[0055] Furthermore, when the sliding plate 302 slides upward, the sliding plate 302 simultaneously drives the connecting column 301 and the linkage pull rod 210 to move upward, and the linkage pull rod 210 drives the conical push block 211 to move upward, and when the bottom of the upper insert cylinder 202 contacts the top of the fixed bottom cylinder 201, the sliding column 206 and the pull block 303 are just in the same vertical plane. At this time, the upward movement of the conical push block 211 can squeeze the first ball 208 through the conical surface of the conical push block 211 to slide in the direction away from the conical push block 211, thereby causing the first ball 208, the sliding column 206 and the second ball 209 to slide at the same time until the outer surface of the bottom column of the conical push block 211 contacts the first ball 208, the first ball 208 stops sliding, and the reset spring 207 enters a compressed state. At this time, the second ball 209 is inserted into the annular groove 203, and the outer surface of the second ball 209 contacts the annular groove 203.

[0056] By setting the conical surface of the conical push block 211, the linkage pull rod 210 slides upward once, and the conical surface of the conical push block 211 can squeeze multiple first balls 208 to slide outward at the same time, thereby simultaneously allowing multiple second balls 209 to enter the annular groove 203, and then through the plug-in limit of the above-mentioned plug plate 305 and the upper slot 309, the linkage pull rod 210 and the conical push block 211 cannot slide downward. At this time, the fixed insert 204 cannot slide upward under the plug-in limit of the second ball 209 and the annular groove 203, thereby completing the installation between the upper insert tube 202 and the annular groove 203.

[0057] After the installation is completed, the second ball 209 and the annular groove 203 are arranged so that when the first catalyst body 11 and the second catalyst body 12 are adjusted in angle, the plug-in limit between the plug plate 305 and the upper slot 309 and the plug-in limit between the second ball 209 and the annular groove 203 make it possible for the first catalyst body 11 and the second catalyst body 12 to be always in contact with the top of the fixed bottom cylinder 201 through the limit when an axial external force is applied, and no axial movement occurs, thereby improving the stability of the upper plug cylinder 202 and the fixed bottom cylinder 201 when they rotate relative to each other, and through the rotation of the second ball 209, when the upper plug cylinder 202 and the fixed plug tube 204 rotate in the fixed bottom cylinder 201, the fixed plug tube 204 can be reduced in the fixed bottom cylinder 201 The friction force during rotation ensures the smoothness of the rotation of the upper insert tube 202 and the fixed insert tube 204 and the fixed bottom tube 201. Compared with the hinge connection in the prior art, on the basis of ensuring stability and smoothness, the pull block 303 slides up and down, so that the linkage pull rod 210 drives the conical push block 211 to slide up and down, and with the cooperation of the reset spring 207, the second ball 209 is inserted into or disengaged from the annular groove 203. The operation can be completed without the aid of tools, and the fixed insert tube 204 and the fixed bottom tube 201 can be easily connected. Not only can the installation angle of the first catalyst body 11 and the second catalyst body 12 be flexibly controlled, but it is also convenient for the subsequent disassembly and maintenance of the first catalyst body 11 and the second catalyst body 12.

[0058] By pulling the pull block 303, the sliding plate 302 slides upward for a distance. At the same time, by connecting the push-pull sheet 304 and the spring telescopic rod, the plug plate 305 is inserted into the upper slot 309 from the lower slot, thereby completing the fixation of the sliding plate 302. Through the setting of the pull block 303 and the connecting push-pull sheet 304, a single pull of the pull block 303 can drive multiple plug plates 305 to slide inward or outward at the same time, thereby completing the fixation of the sliding plate 302 at multiple angles. At the same time, the serrated setting of the plug plate 305 and the slot 309 improves the friction force when the plug plate 305 and the slot 309 are plugged in, thereby improving the fixing effect of the sliding plate 302, thereby preventing the linkage pull rod 210 and the conical push block 211 from shaking up and down during use, thereby ensuring the stability of the second ball 209 when inserted into the annular groove 203.

[0059] Please refer to the above working process Figures 1 to 9 .

[0060] The following is the working process of the pressing and extruding mechanism to squeeze out the lubricating fluid:

[0061] Furthermore, before the fixed insert tube 204 is inserted into the fixed bottom cylinder 201, the connecting tube 401 can be pulled downward to disengage the connecting tube 401 from the fixed insert tube 204, and then the lubricating liquid can be added to the compression tube 402. After the addition is completed, the connecting tube 401 is pushed to re-engage with the bottom of the fixed insert tube 204, and then the fixed insert tube 204 is inserted into the fixed bottom cylinder 201. During the insertion, the compression tube 402 is compressed by the downward pressure, so that the lubricating liquid in the compression tube 402 flows out from the liquid outlet 404 through the connecting tube 401 and the connecting channel, and then through the liquid outlet holes 404 arranged at equal distances, the lubricating liquid can be evenly attached between the fixed insert tube 204 and the fixed bottom cylinder 201. By installing the fixed insert tube 204 and the fixed bottom cylinder 201, the lubricating liquid is evenly distributed. Added between the fixed insert tube 204 and the fixed base cylinder 201, compared with manual spraying and spraying with a sprayer, while ensuring uniformity, it also saves the use of electrical resources. At the same time, the lubricating liquid is sprayed by inserting the fixed insert tube 204 and squeezing the compression tube 402 at the same time, saving an extra spraying step and improving the uniformity of spraying the fixed insert tube 204 and the fixed base cylinder 201. The concave and convex annular setting of the compression tube 402 makes it easier to compress when it is under pressure. Through the setting of the third ball 403, when the fixed insert tube 204 and the fixed base cylinder 201 rotate relative to each other, the friction between the bottom end of the fixed insert tube 204 and the bottom end of the inner cavity of the fixed base cylinder 201 can be reduced by the rotation of the compression tube 402, further improving the smoothness of the rotation of the fixed insert tube 204 and the fixed base cylinder 201.
