Description

Technical Field

[0001] The present invention relates to the technical field of electrostatic precipitators, and in particular to an inlet flue pipe connection device and method for an ultra-low emission wet electrostatic precipitator. Background Technique

[0002] Electrostatic precipitators are essential auxiliary equipment for dust removal. An important structure in an electrostatic precipitator is the inlet and outlet trumpet, which is a transition section between the flue and the electric field. Flange connections are usually selected between the inlet and outlet trumpets and the flue. Traditional flange connections use all-bolt fixed connections. Due to the huge volume of the electrostatic precipitator, the working height between the inlet and outlet trumpets and the flue is very high, and hoisting equipment needs to be used to assist in centering installation. During this process, the flanges between the flange of the inlet and outlet trumpet and the inlet and outlet flue will shift, shake, and misalign. The installation fit is difficult, the installation difficulty is high, the workload of workers is large, the efficiency is low, and forced installation often causes the center between the inlet and outlet trumpet and the flue to shift, and leakage often occurs, making it difficult to ensure the function of the electrostatic precipitator and causing environmental pollution.

[0003] "An adjustable wet electrostatic precipitator for ultra-low emission of flue gas" in the publication number CN210994788U discloses including a main body, an inlet trumpet is arranged on one side of the main body, a smoke inlet pipe is arranged on one side of the inlet trumpet, a first flange and a second flange are respectively arranged between the smoke inlet pipe and the inlet trumpet, and two groups of positioning mechanisms are arranged between the first flange and the second flange. The two groups of positioning mechanisms include a first mounting block and a second mounting block; through the designed positioning mechanism, it is avoided that the bolts and the threaded holes are misaligned due to shaking during the hoisting and assembly process, which is convenient for operators to install and improves the installation speed; however, this positioning mechanism is fixed by a spring. Due to the elasticity of the spring, during the installation process, the spring will drive the slider to shake, which will cause the positioning mechanism to loosen, affect the installation work, and reduce the stability. Summary of the Invention

[0004] In order to overcome the deficiencies of the prior art, the present invention provides an inlet flue pipe connection device and method for an ultra-low emission wet electrostatic precipitator. An installation block is arranged on one side of the flange on the side of the inlet trumpet, the installation block is inserted with a positioning insert block, a positioning jack is arranged on the smoke inlet flange of the smoke inlet pipe, and the positioning insert block is inserted into the positioning jack for positioning by magnetic attraction. At the same time, the limiting groove arranged at the bottom of the positioning insert block is magnetically attracted to the outer surface of the smoke inlet pipe for limiting, preventing the flange installation from shaking and misaligning, with accurate positioning, quick and simple installation of the smoke inlet pipe and the inlet trumpet, stable installation, small workload of operators, and high efficiency.

[0005] In order to achieve the above object, the present invention is realized by adopting the following technical solutions:

[0006] An inlet flue gas pipe connection device for an ultra-low emission wet electrostatic precipitator, comprising an electrostatic precipitator main body. An inlet horn is arranged on one side of the electrostatic precipitator main body. A flange arranged at one end of the inlet horn is connected to a flue gas pipe flange arranged on the inlet flue gas pipe. A plurality of mounting blocks are arranged on the outer circumference of one side of the flange. The mounting blocks are inserted with positioning blocks. The positioning blocks pass through the flange, and the flue gas pipe flange is provided with positioning holes corresponding to the positioning blocks. A limiting block is inserted at the bottom of the positioning block, and a magnetic attraction device is arranged inside the mounting block.

[0007] Further, the magnetic attraction device includes an upper electromagnetic block, a lower electromagnetic block, a traction block, a traction rope, a moving plate, a mounting plate, a connecting rod and a return spring. The upper electromagnetic block and the lower electromagnetic block are arranged on the inner wall of the mounting block away from the positioning block. The mounting plate is fixedly arranged inside the mounting block. A moving plate is slidably arranged at a position corresponding to the lower electromagnetic block between the lower electromagnetic block and the mounting plate. A connecting rod is arranged on the side of the moving plate away from the lower electromagnetic block. The other end of the connecting rod passes through the mounting plate and is connected to the positioning block. A return spring is arranged between the mounting plate and the positioning block. A traction block is slidably arranged at a position corresponding to the upper electromagnetic block. A traction rope is arranged on one side of the traction plate. One end of the traction rope passes through the moving plate, the mounting plate and the inside of the positioning block and is connected to the limiting block.

[0008] Further, a plurality of fixing threaded holes two are arranged on the outer surface of the flange, and a plurality of fixing threaded holes one are arranged on the outer surface of the flue gas pipe flange. The fixing threaded holes one and the fixing threaded holes two correspond to each other.

[0009] Further, a limiting sliding groove one is arranged on the inner wall of the mounting block on the side slidably connected to the moving plate.

[0010] Further, a limiting sliding groove two is arranged on the inner wall of the mounting block on the side slidably connected to the positioning block.

[0011] Further, a limiting sliding groove three is arranged on the inner wall of the mounting block on the side slidably connected to the traction block.

[0012] Further, a magnetic attraction block is arranged at the outer end of the limiting block, and the bottom radius of the magnetic attraction block corresponds to the outer diameter of the inlet flue gas pipe.

[0013] Further, the connection method of the inlet flue gas pipe connection device for the ultra-low emission wet electrostatic precipitator includes the following contents:

[0014] S1. When installing the inlet flue gas pipe and the inlet horn, the upper electromagnetic block is electrified to generate a magnetic attraction effect. Under the action of the upper electromagnetic block, the upper electromagnetic block generates a magnetic attraction effect on the traction plate. The traction plate slides towards the side of the upper electromagnetic block. Furthermore, the traction plate drives the traction rope to traction the limiting block, so that the limiting block can retract and be inserted into the inside of the positioning block.

[0015] S2. After the limit block retracts, activate the magnetic attraction of the lower electromagnet. Under its magnetic force, the lower electromagnet attracts the moving plate, causing the moving plate to slide towards the lower electromagnet, driving the positioning plug to slide into the interior of the mounting block, and compressing the return spring between the positioning plug and the mounting plate.

[0016] S3. After the flue pipe flange and the flange are aligned, the lower electromagnet loses power, and the return spring rebounds. Under the elastic force of the return spring, it pushes the positioning plug to insert through the corresponding positioning hole. The upper magnetic attraction block loses power, and the traction rope no longer pulls the limit block. The magnetic attraction block on the bottom surface of the limit block makes the limit block disengage from the interior of the positioning plug under the action of magnetic force and adsorb on the outer surface of the inlet flue pipe to limit and fix the connection between the flue pipe flange and the flange, and then install the bolts between the flange and the flue pipe flange.

[0017] S4. When disassembling the inlet flue pipe and the inlet bell, remove the bolts. The upper electromagnet is powered on to generate magnetic attraction. The upper electromagnet attracts the traction plate to slide towards the upper electromagnet, driving the traction rope to retract the limit block and insert it into the interior of the positioning plug. The lower electromagnet is powered on to attract the moving plate to slide and drive the positioning plug to retract into the positioning block, and the disassembly of the inlet flue pipe and the inlet bell is completed.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1) The flange connection between the inlet flue pipe and the inlet bell of the electrostatic precipitator is positioned by the positioning plug and the positioning hole. The positioning is controlled by a magnetic attraction device, with accurate positioning, avoiding shaking during hoisting and assembly, preventing misalignment between the bolt and the threaded hole, facilitating the installation by the operator, improving the installation speed, and enhancing the stability during installation.

[0020] 2) The limit block is controlled by a magnetic attraction device and adsorbs on the outer surface of the inlet flue pipe for further accurate positioning. The magnetic attraction positioning eliminates the need for manual positioning, with simple positioning, reducing the installation difficulty, decreasing the workload of workers, and improving the installation efficiency.

[0021] 3) The positioning plug is slidably connected inside the second limit chute to limit its movement and make its operation more stable, enhancing the stability during installation.

[0022] 4) The flange installation accuracy of the inlet flue pipe and the inlet bell of the electrostatic precipitator is high, avoiding the center offset between the inlet and outlet bells and the flue, preventing leakage accidents such as running, leaking, dripping, and leaking at the flange position, avoiding environmental pollution, and improving the ecological environment.

Detailed implementation manners

[0028] The following further describes the detailed implementation manners of the present invention with reference to the accompanying drawings:

[0029] As Figures 1-4 shown, a connection device for the inlet flue pipe of an ultra-low emission wet electrostatic precipitator includes a main body 1 of the electrostatic precipitator. A ash hopper 2 is provided at the lower end of the main body 1 of the electrostatic precipitator. An inlet horn 12 is provided on one side of the main body 1 of the electrostatic precipitator. A flange 10 is provided at one end of the inlet horn 12. A plurality of mounting blocks 3 are installed on the outer surface of one side of the inlet horn 12. A positioning plug 9 is inserted into one end of the mounting block 3. One end of the positioning plug 9 passes through the flange 10 and is provided on the outer surface of the other side. A plurality of second fixing threaded holes 11 are formed on the outer surface of the flange 10. The inlet horn 12 is connected to the inlet flue pipe 6 through the flange 10. A flue pipe flange 5 corresponding to the flange 10 is provided on one side of the inlet flue pipe 6. A first fixing threaded hole 8 corresponding to the second fixing threaded hole 11 is formed on the outer surface of the flue pipe flange 5. A positioning jack 7 corresponding to the positioning plug 9 is formed on the surface of the flue pipe flange 5. A limit block 4 corresponding to the inlet flue pipe 6 is inserted into one end of the positioning plug 9. Through the above design, under the action of the positioning plug 9 and the limit block 4, the connection between the flue pipe flange 5 and the flange 10 can be limited and fixed during installation, facilitating subsequent installation and improving convenience and stability.

[0030] As Figures 1-3As shown in the figure, an electromagnet 16 is installed at one end inside the mounting block 3. A mounting plate 19 is provided inside the mounting block 3. A return spring 22 is installed on one side of the mounting plate 19. One end of the return spring 22 is connected to a positioning plug 9. A moving plate 18 corresponding to the electromagnet 16 is slidably connected inside the mounting block 3. The moving plate 18 is arranged between the mounting plate 19 and the electromagnet 16. One end of the positioning plug 9 is provided with a connecting rod 21. The other end of the connecting rod 21 penetrates through the inside of the return spring 22 and the mounting plate 19, and is arranged on one side surface of the moving plate 18. When the electromagnet 16 is activated, under the action of its magnetic force, the moving plate 18 is magnetically attracted, so that the moving plate 18 drives the positioning plug 9 to move into the mounting block 3. When installation and positioning are required, the electromagnet 16 is turned off. Under the elastic force of the return spring 22, the positioning plug 9 is pushed to be inserted into the corresponding positioning hole 7 for positioning and fixing, improving the stability during installation.

[0031] As Figures 2-4 shown, an upper electromagnet 15 is provided on one side inside the mounting block 3. A traction plate 14 corresponding to the upper electromagnet 15 is slidably connected to the upper end inside the mounting block 3. The traction plate 14 is arranged between the moving plate 18 and the upper electromagnet 15. One side of the traction plate 14 is provided with a traction rope 13. One end of the traction rope 13 penetrates through the inside of the moving plate 18, the mounting plate 19 and the positioning plug 9, and is arranged on one side of the limiting block 4. Under the action of the upper electromagnet 15, a magnetic attraction effect is generated on the traction plate 14, so that the traction plate 14 drives the traction rope 13 to traction the limiting block 4, enabling the limiting block 4 to retract into the positioning plug 9, improving convenience.

[0032] As Figure 4 shown, a magnetic block 24 corresponding to the smoke inlet pipe 6 is installed inside one end of the limiting block 4. Through the magnetic attraction of the magnetic block 24, it is adsorbed on the surface of the smoke inlet pipe 6, thereby fixing the limiting block 4 and reducing the possibility of its shaking, improving the stability during installation.

[0033] As Figures 1-2 shown, a limiting chute 17 is opened on one side inside the mounting block 3. One end of the moving plate 18 is slidably connected inside the limiting chute 17. By sliding one end of the moving plate 18 inside the limiting chute 17, the movement of the moving plate 18 is limited, making its operation smoother and improving the stability during installation.

[0034] As Figures 1-2 shown, a limiting chute 20 is opened on one side inside the mounting block 3. One end of the positioning plug 9 is slidably connected inside the limiting chute 20. By sliding one end of the positioning plug 9 inside the limiting chute 20, the movement of the positioning plug 9 is limited, making its operation smoother and improving the stability during installation.

[0035] As shown Figure 3 As shown, a limiting sliding groove three 23 corresponding to the traction plate 14 is opened on one side inside the mounting block 3. One end of the traction plate 14 slides inside the limiting sliding groove three 23. By sliding one end of the traction plate 14 inside the limiting sliding groove three 23, the movement thereof is limited, so that its operation is more stable and the stability is improved.

[0036] As shown Figures 1-4 As shown, the connection method of the connection device for the inlet flue pipe of an ultra-low emission wet electrostatic precipitator:

[0037] S1. During installation, under the action of the upper electromagnet 15, a magnetic attraction effect is generated on the traction plate 14, so that the traction plate 14 drives the traction rope 13 to traction the limiting block 4, so that the limiting block 4 can retract into the positioning insert block 9;

[0038] S2. Start the lower electromagnet 16. Under its magnetic force, the moving plate 18 is magnetically attracted, so that the positioning insert block 9 compresses the return spring 22, and then the moving plate 18 drives the positioning insert block 9 to move into the mounting block 3;

[0039] S3. When the flue pipe flange 5 and the flange 10 are aligned, turn off the lower electromagnet 16. Under the elastic force of the return spring 22, the positioning insert block 9 is pushed to insert through the corresponding positioning hole 7. Under the action of the magnetic attraction block 24, the limiting block 4 is separated from the inside of the positioning insert block 9 and adsorbed on the outer surface of the inlet flue pipe 6 to limit and fix the connection between the flue pipe flange 5 and the flange 10, which is convenient for subsequent installation;

[0040] S4. When disassembling the inlet flue pipe 6 and the inlet horn 12, remove the bolts. The upper electromagnet 15 is energized to generate a magnetic attraction effect. The upper electromagnet 15 magnetically attracts the traction plate 14 to slide towards the upper electromagnet 15, driving the traction rope 13 to retract the limiting block 4 into the positioning insert block 9. The lower electromagnet 16 is energized to magnetically attract the moving plate 18 to slide and drive the positioning insert block 9 to retract into the positioning block 3, and the disassembly of the inlet flue pipe 6 and the inlet horn 12 is completed.

[0041] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
