Description

Technical Field

[0001] This invention relates to the field of flue gas environmental protection separation and treatment technology, specifically to an SCR reactor guide plate installation structure. Background Technology

[0002] SCR reactors are core environmental protection equipment in industrial flue gas denitrification systems, widely used in coal-fired power plants, industrial boilers, cement kilns, waste incinerators, and other applications. Their core function is to efficiently remove nitrogen oxides (NOx) from flue gas. x To achieve environmentally compliant emissions, the SCR reactor, during operation, uses a catalyst (mainly vanadium-titanium based, operating temperature 300-400℃) to introduce reducing agents such as ammonia (NH3) into the reactor. These reducing agents selectively react with NO in the flue gas. x A reduction reaction occurs, producing harmless nitrogen (N2) and water (H2O), and it does not react with the large amount of oxygen (O2) present in the flue gas, thus avoiding secondary pollution.

[0003] During the operation of an SCR reactor, flue gas enters the reactor from the flue. Due to pipe bends, diameter changes, or equipment interference, flow deviation and eddies are prone to occur. To avoid this problem, multiple sets of guide plates are installed inside the treatment chamber of the SCR reactor. These guide plates, through preset angles and distribution, force the flue gas to flow along the designed path, ensuring that the flow velocity uniformity of the reactor cross-section (especially the catalyst inlet) meets the requirements. However, during the installation process, the two ends of the guide plates need to be pre-positioned and installed in the designated positions of the treatment chamber by means of threads, and then welded and fixed. Due to the large number of guide plates and the small gap between adjacent sets, the pre-installation of the guide plates is inconvenient. Therefore, we propose an SCR reactor guide plate installation structure. Summary of the Invention

Detailed Implementation

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Example 1

[0032] Please see Figures 1-9 The diagram shows an SCR reactor baffle installation structure, which includes multiple baffle plates 104 disposed inside the SCR reactor. The SCR reactor includes a processing chamber 101, on which an air inlet channel 102 and an exhaust channel 103 are respectively disposed. The multiple baffle plates 104 are arranged in a row inside the processing chamber 101 to guide other air entering through the air inlet channel 102.

[0033] It should be noted that during the separation and treatment of flue gas in the SCR reactor, the flue gas is first pretreated to adjust to 300-400℃ and initially dusted. Then, the reducing agent is evenly injected through the ammonia injection grid and mixed with the flue gas. The mixed gas enters the interior of the treatment chamber 101 through the inlet channel 102. Through the internal catalytic action, the nitrogen oxides in the flue gas are reduced to harmless nitrogen and water. Finally, the purified flue gas is discharged to the outside through the exhaust channel 103. During the flue gas transportation and treatment process, the flue gas is smoothly diverted by multiple sets of guide plates 104 installed inside the treatment chamber 101, eliminating flow field distortion and facilitating efficient separation and treatment of the flue gas.

[0034] In addition, it should be noted that the principle of flue gas separation and treatment by the SCR reactor and the guiding principle of the guide plate 104 are conventional technical means in this application and will not be elaborated on here.

[0035] It also includes an installation component, which is set on the guide plate 104 to assist in the fixed installation of the guide plate 104 inside the processing box 101;

[0036] Driver components are components that are set on the installation components to assist drivers during the installation process;

[0037] And, a sealing assembly and a support assembly provided on the mounting assembly to assist in the sealing and support of the housing 101 during the installation process;

[0038] It should be noted that during the installation of the multiple sets of guide plates 104 on the SCR reactor, the guide plates 104 are positioned and installed through the cooperation of the installation components, drive components, sealing components, and support components. The entire positioning and installation process is simple and convenient, and is not affected by the internal space, which facilitates the rapid and accurate positioning and installation of the guide plates 104. In addition, during the installation process, the transmission can simultaneously ensure the compressive support force and sealing effect between the guide plates 104 and the treatment box 101, which is conducive to the stable flow guiding of the guide plates 104 in the future.

[0039] Preferably, the mounting assembly includes arc-shaped covers 201 disposed on both sides of the guide plate body 104. The two ends of the guide plate body 104 are slidably connected to two sets of arc-shaped covers 201. A guide assembly for auxiliary guiding connection is provided between the end of the guide plate body 104 and the arc-shaped cover 201. An arc-shaped sealing ring 203 for abutment sealing is fixed between the guide plate body 104 and the interior of the arc-shaped cover 201. An arc-shaped sealing ring 203 for contact sealing with the interior of the processing chamber 101 is fixed on the arc-shaped cover 201. The arc-shaped plate 202 is pressed against the wall; the driving assembly includes a mounting hole 401 opened on the guide plate body 104, a double-ended lead screw 402 is rotatably connected to the mounting hole 401, and the threads at both ends of the double-ended lead screw 402 are arranged in opposite directions. A threaded tube 403 is fixed inside the arc-shaped cover 201. Two sets of threaded tubes 403 are respectively engaged with the two ends of the double-ended lead screw 402. A set of arc-shaped covers 201 is provided with a rotating assembly for rotating the double-ended lead screw 402.

[0040] It should be noted that: the rotating assembly drives the double-ended lead screw 402 to rotate. During the rotation of the double-ended lead screw 402, because the threads at both ends of the double-ended lead screw 402 are set in opposite directions, the threaded tubes 403 on the two sets of arc-shaped covers 201 mesh with the two ends of the double-ended lead screw 402 respectively, causing the two sets of arc-shaped covers 201 to move under force. During the movement, through the sliding guidance of multiple sets of sleeves 301 and slide rods 302, the two sets of arc-shaped covers 201 move away from each other after being subjected to force. Through the mutual movement of the two sets of arc-shaped covers 201, the two sets of arc-shaped plates 202 are driven to abut against the inner wall of the processing box 101. Through the abutment and compression action, the positioning and installation of the guide plate 104 is achieved.

[0041] Preferably, the rotating assembly includes a worm gear 504, and a transmission assembly for auxiliary connection transmission is provided between the worm gear 504 and the double-ended lead screw 402. A drive rod 501 is rotatably connected to the arc-shaped cover 201. One end of the drive rod 501 is located inside the arc-shaped cover 201 and a worm 503 is fixed thereon. The worm 503 and the worm gear 504 are meshed with each other. The other end of the drive rod 501 is located outside the arc-shaped cover 201 and a drive pin 502 is fixed thereon. The end of the drive pin 502 is provided with a hexagonal hole for inserting a hexagonal wrench.

[0042] It should be noted that: the guide plate 104 is placed in a designated position inside the processing box 101. After the position of the guide plate 104 is determined, the drive pin 502 is rotated at the bottom of the guide plate 104 using an external tool. During the rotation of the drive pin 502, the worm gear 503 is driven to rotate through the connection of the drive rod 501. During the rotation of the worm gear 503, the transmission sleeve 601 is driven to rotate through the meshing transmission between the worm gear 503 and the worm wheel 504. During the rotation of the transmission sleeve 601, the double-ended lead screw 402 is driven to rotate through the connection and transmission of multiple sets of transmission blocks 603 and multiple sets of transmission grooves 602.

[0043] Preferably, the transmission assembly includes a transmission sleeve 601 sleeved on the outside of the double-ended lead screw 402, a worm gear 504 sleeved and fixed on the transmission sleeve 601, a plurality of transmission grooves 602 are provided inside the transmission sleeve 601, and the plurality of transmission grooves 602 are arranged in a ring array on the transmission sleeve 601, a transmission block 603 is slidably connected to the transmission groove 602, the transmission block 603 is fixed on the outside of the double-ended lead screw 402, and a connecting assembly for assisting in the rotatable connection of the transmission sleeve 601 is provided inside the arc-shaped cover 201.

[0044] It should be noted that: through transmission, the transmission sleeve 601 is driven to rotate. During the rotation of the transmission sleeve 601, the double-ended lead screw 402 is driven to rotate through the connection and transmission action of multiple sets of transmission blocks 603 and multiple sets of transmission grooves 602 respectively. During the transmission process, through the sliding action of multiple sets of transmission blocks 603 on the transmission grooves 602, the double-ended lead screw 402 can be driven to rotate synchronously when the transmission sleeve 601 moves axially.

[0045] Preferably, the connecting assembly includes a mounting bracket 701 fixed inside the arc-shaped cover 201. The mounting bracket 701 has a through hole, the transmission sleeve 601 is located inside the through hole, the through hole has a connecting groove 702, and a connecting ring 703 is rotatably connected inside the connecting groove 702. The connecting ring 703 is sleeved and fixed to the outside of the transmission sleeve 601.

[0046] It should be noted that during the movement of the arc-shaped cover 201, the connection between the mounting bracket 701, the connecting groove 702, and the connecting ring 703 can drive the transmission sleeve 601 and the worm gear 504 on the transmission sleeve 601 to move synchronously. In addition, the connection groove 702 and the connecting ring 703 can assist the transmission sleeve 601 to rotate on the mounting bracket 701.

[0047] Preferably, the guide assembly includes multiple sets of sleeves 301 fixed inside the arc-shaped cover 201, and a slide rod 302 is slidably connected to the sleeve 301. One end of the slide rod 302 is fixed to the end of the guide plate 104.

[0048] It should be noted here that: the multiple sets of sleeves 301 and slide rods 302 facilitate the movement guidance of the arc-shaped cover 201 after being subjected to force.

[0049] Preferably, the support assembly includes an arcuate groove 801 formed on the arcuate plate 202, and a support plate 802 for supporting against the inner wall of the processing box 101 is connected to the arcuate groove 801 by a spring 803. Multiple sets of springs 803 are arranged inside the arcuate groove 801. A sealing assembly is arranged on the support plate 802, and a pressure supply assembly for supplying pressure to the sealing assembly is arranged on the arcuate groove 801.

[0050] It should be noted that during the process of driving the two sets of arc-shaped plates 202 to move away from each other, the supporting plate 802 is driven to move by the connecting and supporting action of the spring 803. During the movement of the supporting plate 802, the supporting plate 802 and the sealing airbag 902 on the supporting plate 802 abut against the inner wall of the processing box 101. With the continued driving of the arc-shaped plates 202 and the abutting and limiting action of the inner wall of the processing box 101 against the supporting plate 802 and the sealing airbag 902, the supporting plate 802 moves relative to the inside of the arc-shaped groove 801. During the relative movement, the spring 803 is continuously compressed. Through the elastic force of the spring 803, the supporting plate 802 is pushed to abut against the inner wall of the processing box 101 with greater force, ensuring the abutting support effect and further ensuring the stability of the positioning installation.

[0051] Preferably, the sealing assembly includes a mounting groove 901 formed on the support plate 802, and a sealing airbag 902 for pressing against the inner wall of the processing box 101 is installed inside the mounting groove 901.

[0052] It should be noted here that during the process of driving the two sets of arc plates 202 to move away from each other, the support plate 802 is driven to move by the connecting support of the spring 803. During the movement of the support plate 802, the support plate 802 and the sealing airbag 902 on the support plate 802 abut against the inner wall of the processing box 101. After abutting, with the subsequent transmission, pressure is supplied to the inside of the sealing airbag 902. During the pressure supply process, the pressure inside the sealing airbag 902 makes the sealing airbag 902 fully fit against the inner wall of the processing box 101. Through the fitting effect, the sealing effect between the guide plate 104 and the processing box 101 is guaranteed during the installation process, which facilitates the subsequent flow diversion.

[0053] Additionally, it should be noted that the sealed airbag 902 is pre-filled with gas to facilitate rapid expansion and deformation after stamping.

[0054] Preferably, multiple sets of pressure supply components are provided, and each set of pressure supply components is matched with each set of springs 803. The pressure supply component includes a mounting cylinder 1001 fixed inside the arc-shaped groove 801, a spring 803 sleeved on the outside of the mounting cylinder 1001, a piston ring 1002 slidably connected inside the mounting cylinder 1001, a pressure supply pipe 1003 connected to the piston ring 1002, and the pressure supply pipe 1003 fixed on the support plate 802 and connected to the sealing airbag 902.

[0055] It should be noted that during the relative movement of the support plate 802 inside the arc groove 801, the piston ring 1002 is pushed to move inside the mounting cylinder 1001 through the connection of the pressure supply pipe 1003. During the movement, part of the gas inside the mounting cylinder 1001 is squeezed and transported to the inside of the sealing airbag 902 through the pressure supply pipe 1003 to supply pressure to the inside of the sealing airbag 902.

[0056] In this solution: an SCR reactor baffle mounting structure includes the following steps:

[0057] During the separation and treatment of flue gas in the SCR reactor, the flue gas is first pretreated to adjust to 300-400℃ and initially dusted. Then, the reducing agent is evenly injected through the ammonia injection grid and mixed with the flue gas. The mixed gas enters the interior of the treatment chamber 101 through the inlet channel 102. Through the internal catalytic action, the nitrogen oxides in the flue gas are reduced to harmless nitrogen and water. Finally, the purified flue gas is discharged to the outside through the exhaust channel 103. During the flue gas transportation and treatment process, the flue gas is smoothly diverted by multiple sets of guide plates 104 installed inside the treatment chamber 101, eliminating flow field distortion and facilitating efficient separation and treatment of the flue gas.

[0058] The installation of multiple sets of guide vanes 104 on the SCR reactor requires two steps. The first step is to pre-position and install the guide vanes 104. The second step is to weld and fix the positioned guide vanes 104 to ensure their stability after installation. During the pre-positioning process, the guide vanes 104 are placed in designated positions inside the treatment chamber 101. After the position of the guide vanes 104 is determined, external tools (hex wrenches) are used to adjust the bottom of the guide vanes 104. The driving pin 502 rotates, and during this rotation, the worm 503 is driven to rotate through the connection of the driving rod 501. During the rotation of the worm 503, the transmission sleeve 601 is driven to rotate through the meshing transmission between the worm 503 and the worm wheel 504. During the rotation of the transmission sleeve 601, the double-ended lead screw 402 is driven to rotate through the connection of multiple sets of transmission blocks 603 and multiple sets of transmission grooves 602. During the rotation of the double-ended lead screw 402, the threads at both ends of the double-ended lead screw 402 rotate... Conversely, the two sets of arc-shaped covers 201 are driven by the meshing of threaded tubes 403 on each end of the double-ended lead screw 402. This causes the two sets of arc-shaped covers 201 to move under force. During this movement, the sliding guide action of multiple sets of sleeves 301 and slide rods 302 causes the two sets of arc-shaped covers 201 to move away from each other. This mutual movement of the two sets of arc-shaped covers 201 drives the two sets of arc-shaped plates 202 to abut against the inner wall of the processing box 101. Through this abutting and pressing action, the guide plate 104 is positioned and installed. During installation, the drive pin 502 can be rotated from the bottom of the guide plate 104. The operation is simple and convenient and is not affected by the internal space. This facilitates the quick and accurate positioning and installation of the guide plate 104. During the process of driving the two sets of arc-shaped covers 201 to move away from each other, the drive rod 501 and the connecting components drive the worm 503 and the worm wheel 504 on the transmission sleeve 601 to move synchronously. This allows the worm wheel 504 and the worm 503 to maintain a meshing transmission state while the arc-shaped cover 201 moves, which facilitates stable drive operation.

[0059] Furthermore, during the process of driving the two sets of arc-shaped plates 202 to move away from each other, the supporting plate 802 is driven to move by the connecting and supporting action of the spring 803. During the movement of the supporting plate 802, the supporting plate 802 and the sealing airbag 902 on the supporting plate 802 abut against the inner wall of the processing box 101. With the continued driving of the arc-shaped plates 202 and the abutting and limiting action of the inner wall of the processing box 101 against the supporting plate 802 and the sealing airbag 902, the supporting plate 802 undergoes relative movement inside the arc-shaped groove 801. During the relative movement, the spring 803 is continuously compressed. Through the elastic force of the spring 803, the supporting plate 802 is pushed to abut against the inner wall of the processing box 101 with greater force, ensuring the abutting support. The support plate 802 further ensures the stability of the positioning installation. In addition, during the relative movement of the support plate 802 inside the arc groove 801, the piston ring 1002 is pushed to move inside the mounting cylinder 1001 through the connection of the pressure supply pipe 1003. During the movement, part of the gas inside the mounting cylinder 1001 is squeezed and transported to the inside of the sealing airbag 902 through the pressure supply pipe 1003, and the inside of the sealing airbag 902 is pressurized. During the pressurization process, the pressure inside the sealing airbag 902 makes the sealing airbag 902 fully fit with the inner wall of the treatment box 101. Through the fitting effect, the sealing effect between the guide plate 104 and the treatment box 101 is ensured during the installation process, which facilitates subsequent flow diversion.
