[0002] Currently, desulfurization and dust removal of flue gas generated from carbon production typically utilizes integrated wet electrostatic precipitator (WEEP) tower equipment. This equipment, from bottom to top, consists of a desulfurization spray system, a demister, a supporting grid, and a wet electrostatic precipitator. However, in practical use, the demister and grid suffer from clogging and damage. When problems arise, they cannot be quickly and easily disassembled and replaced, significantly impacting overall processing efficiency and requiring improvement. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide a desulfurization wet electrostatic precipitator for flue gas treatment, which can realize quick disassembly and replacement of the two-layer demister assembly and the whole grid plate, so as to solve the above problems.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a desulfurization wet electrostatic precipitator for flue gas treatment, comprising a tower body, an air inlet at the bottom and an air outlet at the top, wherein a desulfurization spray mechanism, a two-layer demister assembly, a grid plate and a wet electrostatic precipitator are arranged sequentially from bottom to top within the tower body between the air inlet and the air outlet. An mounting plate is fixedly mounted on one side of both the demister assembly and the grid plate, and a through groove is opened on the corresponding side of the tower body. Several insertion holes are opened through the mounting plate. A circular arc guide rail is fixedly sleeved on the outer side of the tower body below the demister assembly. First electric sliding blocks are slidably mounted on both sides of the circular arc guide rail. Linear guide rails are fixedly mounted on the top of both first electric sliding blocks. Second electric sliding blocks are slidably mounted on both linear guide rails. Support plates are fixedly mounted on both second electric sliding blocks. A vertically arranged sealing plate is fixedly connected to one end of the plate near the tower body. The sealing plate and the mounting plate are respectively provided with slots. A double-rod hydraulic cylinder is vertically fixed on the outer side of the sealing plate between the lower slot and the middle slot, and a single-rod hydraulic cylinder is vertically fixed on the outer side of the sealing plate between the middle slot and the upper slot. The two piston rods of the double-rod hydraulic cylinder and the upper end of the piston rod of the single-rod hydraulic cylinder are fixedly connected to a fixing plate. Several fixing rods are fixed on the side of the fixing plate away from the corresponding piston rod in a rectangular array. The sealing plate abuts against the outer side of the tower body where the through slot is located. The demister assembly and the grid plate abut against the sealing plate through the through slot, and the mounting plate is inserted through into the corresponding slot. The fixing plate abuts against the adjacent mounting plate, and the fixing rods on it correspond one-to-one with the insertion holes on the corresponding mounting plate and are inserted through.

[0005] Preferably, the through groove is adapted to the corresponding demister assembly and grille.

[0006] Preferably, the slot is adapted to the corresponding mounting plate.

[0007] Preferably, the fixing rod is adapted to the corresponding insertion hole.

[0008] Preferably, a vertically arranged electric push rod is fixedly mounted on the outer wall of the tower body on the upper side of the sealing plate. The telescopic end of the electric push rod faces downward and a blind hole adapted to the telescopic end of the electric push rod is opened on the top of the corresponding sealing plate. The telescopic end of the electric push rod is inserted into the corresponding blind hole.

[0009] Preferably, the demister assembly consists of a ridge demister and two tube demisters distributed on the upper and lower sides of the ridge demister.

[0010] Preferably, L-shaped insulating boxes are provided on the outer sides of the tower body at both the upper and lower ends on both sides of the wet electrostatic precipitator. The cathode conductive rod of the wet electrostatic precipitator extends into the insulating box and is fixed inside the porcelain insulator in the insulating box. A hollow air distribution plate is provided on the inner wall of the insulating box around the porcelain insulator. Several air outlet holes are opened on the inner side of the air distribution plate. A hot air conveying pipeline is connected to the outer side of the air distribution plate.

[0011] The beneficial effects of this utility model are as follows: Before use, the demister assembly and the grid plate can be installed on a sealing plate. The specific installation steps are as follows: First, align the mounting plates of the two sets of demister assemblies with the corresponding slots and insert them into place. Then, operate the double-rod hydraulic cylinder to extend its two piston rods, driving the corresponding fixing plate to move until the fixing plate presses against the corresponding mounting plate and the fixing rod is inserted into the corresponding hole. This completes the installation of the two sets of demister assemblies. Next, align the mounting plate on the grid plate with the corresponding slots and insert it into place. Then, operate the single-rod hydraulic cylinder to extend its piston rod, driving the corresponding fixing plate to move until the fixing plate presses against the corresponding mounting plate and the fixing rod is inserted into the corresponding hole. This completes the installation of the grid plate assembly. Then, operate the corresponding first electric slide to rotate the corresponding sealing plate to the side where the through groove is located, so that the demister assembly and the grid plate on the sealing plate are aligned with the corresponding through groove. Next, the corresponding second electric slide is operated, driving the corresponding sealing plate towards the tower body until the sealing plate abuts against the tower body. At this point, the demister assembly and the grid plate can be inserted into the tower body through the corresponding through slots, thus completing the overall installation of the demister assembly and the grid plate, ensuring a stable installation without affecting subsequent use. Afterward, the flue gas to be treated can be input through the air inlet, allowing the flue gas to flow from bottom to top through the desulfurization spray mechanism, the demister assembly, the grid plate, and the wet electrostatic precipitator. After being treated by desulfurization, demisting, and dust removal, the flue gas is discharged from the air outlet to the subsequent process.

[0012] After a period of operation, when the demister assembly and grating plate inside the tower become clogged or damaged and need replacement, the demister assembly and grating plate can be installed on another sealing plate in advance according to the aforementioned steps. Then, stop the machine and operate the second electric slide corresponding to the sealing plate abutting against the tower body. This will move the corresponding sealing plate away from the tower body, allowing the original demister assembly and grating plate to be pulled out of the tower body. Then, operate the two first electric slides to exchange their positions, allowing the new demister assembly and grating plate to be rotated to the side where the through slot is located. Then, insert the new demister assembly and grating plate into place according to the aforementioned steps and continue using it. At the same time, operate the double-rod hydraulic cylinder and single-rod hydraulic cylinder corresponding to the problematic demister assembly and grating plate, causing their piston rods to retract and reset, driving the fixing plate back and causing the fixing rod to exit from the corresponding insertion hole. This will release the insertion and fixing of the corresponding mounting plate. Then, pull out the mounting plate, and the problematic demister assembly and grating plate can be removed from the corresponding sealing plate, ready for subsequent replacement operations. This allows for quick and easy disassembly and replacement of the two-layer demister assembly and the entire grille, greatly reducing the adverse impact on overall processing efficiency and making the overall use more flexible, convenient, and practical.

Detailed Implementation

[0021] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0022] like Figures 1 to 7 As shown, a desulfurization wet electrostatic precipitator for flue gas treatment includes a tower body 1. The lower part of the tower body 1 has an air inlet 2, and the top has an air outlet 3. Between the air inlet 2 and the air outlet 3, the tower body 1 contains, from bottom to top, a desulfurization spray mechanism 4, a two-layer demister assembly 5, a grid plate 6, and a wet electrostatic precipitator 7. Mounting plates 8 are fixed to one side of both the demister assembly 5 and the grid plate 6, and corresponding slots 9 are formed on the side of the tower body 1 on that side. Several insertion holes 10 are formed through the mounting plates 8. A circular arc guide rail 11 is fixedly fitted to the outer side of the tower body 1 below the demister assembly 5. First electric slide blocks 12 are slidably mounted on both sides of the circular arc guide rail 11. Linear guide rails 13 are fixedly mounted on the top of each of the two first electric slide blocks 12. Second electric slide blocks 14 are slidably mounted on each of the two linear guide rails 13. Support plates 15 are fixedly mounted on each of the two second electric slide blocks 14. A vertically arranged sealing plate 16 is fixedly connected to one end of the support plate 15 near the tower body 1. The sealing plate 16 corresponds to the position of the mounting plate 8. Each slot 17 is provided through. A double-rod hydraulic cylinder 18 is vertically fixed on the outer side of the sealing plate 16 between the lower slot 17 and the middle slot 17. A single-rod hydraulic cylinder 19 is vertically fixed on the outer side of the sealing plate 16 between the middle slot 17 and the upper slot 17. The two piston rods of the double-rod hydraulic cylinder 18 and the upward-facing piston rod of the single-rod hydraulic cylinder 10 are all fixedly connected to a fixing plate 20. Several fixing rods 21 arranged in a rectangular array are fixed on the side of the fixing plate 20 away from the corresponding piston rod. The sealing plate 16 abuts against the outer side of the tower body 1 where the through slot 9 is located. The demister assembly 5 and the grid plate 6 abut against the sealing plate 16 through the through slot 9, and the mounting plate 8 is inserted through into the corresponding slot 17. The fixing plate 20 abuts against the adjacent mounting plate 8, and the fixing rods 21 on it correspond one-to-one with the insertion holes 10 on the corresponding mounting plate 8 and are inserted through.

[0023] Before use, the demister assembly 5 and the grid plate 6 can be installed on the sealing plate 16. The specific installation steps are as follows: First, align the mounting plates 8 of the two sets of demister assemblies 5 with the corresponding slots 17 and insert them into place. Then, operate the double-rod hydraulic cylinder 18 to extend its two piston rods, driving the corresponding fixing plate 20 to move until the fixing plate 20 presses against the corresponding mounting plate 8 and the fixing rod 21 is inserted into the corresponding insertion hole 10. This will fix the mounting plates 8 of the two sets of demister assemblies 5, completing the fixed installation of the two demister assemblies 5. Next, align the mounting plate 8 on the grid plate 6 with the corresponding slots 17 and insert it into place. Then, operate the single-rod hydraulic cylinder 19 to extend its piston rod, driving the corresponding fixing plate 20 to move until the fixing plate 20 presses against the corresponding mounting plate 8 and the fixing rod 21 is inserted into the corresponding insertion hole 10. This will fix the mounting plate 8 of the grid plate 6 assembly, completing the fixed installation of the grid plate 6. Then, the corresponding first electric slide 12 is operated, driving the corresponding sealing plate 16 to rotate to the side where the through slot 9 is located, so that the demister assembly 5 and the grid plate 6 on the sealing plate 16 are aligned with the corresponding through slot 9. Next, the corresponding second electric slide 14 is operated, driving the corresponding sealing plate 16 to move towards the tower body 1 until the sealing plate 16 abuts against the tower body 1, so that the demister assembly 5 and the grid plate 6 can be inserted into the tower body 2 through the corresponding through slot 9, thus completing the overall installation of the demister assembly 5 and the grid plate 6 and ensuring that the installation is secure and does not affect subsequent use. After that, the flue gas to be treated can be input through the air inlet 2, so that the flue gas flows from bottom to top through the desulfurization spray mechanism 4, the demister assembly 5, the grid plate 6 and the wet electrostatic precipitator 7, and after being treated by desulfurization, demisting and dust removal, it is discharged from the air outlet 3 to the subsequent process.

[0024] After a period of operation, when the demister assembly 5 and grid plate 6 inside the tower body 1 need to be replaced due to blockage or damage, the demister assembly 5 and grid plate 6 can be installed on another sealing plate 16 in advance according to the aforementioned steps. Then, stop the machine and run the second electric slide 14 corresponding to the sealing plate 16 abutting against the tower body 1, so that it moves the corresponding sealing plate 16 away from the tower body 1, and the original demister assembly 5 and grid plate 6 can be pulled out of the tower body 1. Then, run the two first electric slides 12 to exchange positions, so that the new demister assembly 5 and grid plate 6 can be rotated to the side where the through slot 9 is located. Then, insert the new demister assembly 5 and grid plate 6 into place according to the aforementioned steps and continue to use. Simultaneously, the double-rod hydraulic cylinder 18 and single-rod hydraulic cylinder 19 corresponding to the problematic demister assembly 5 and grid plate 6 are operated, causing their piston rods to retract and reset, driving the fixing plate 20 to retract, and causing the fixing rod 21 to exit from the corresponding insertion hole 10. This releases the insertion and fixing of the corresponding mounting plate 8. Then, the mounting plate 8 is pulled out, allowing the problematic demister assembly 5 and grid plate 6 to be removed from the corresponding sealing plate 16, awaiting subsequent replacement. This allows for quick and convenient disassembly and replacement of both layers of demister assemblies 5 and grid plates 6, significantly reducing the adverse impact on overall processing efficiency and making the overall use more flexible, convenient, and practical. The desulfurization spray mechanism 4 and the wet electrostatic precipitator 7 can both utilize existing technology; their specific structures and working principles will not be detailed here.

[0025] In this embodiment, the through groove 9 is adapted to the corresponding demister assembly 5 and the grid plate 6 to ensure that the demister assembly 5 and the grid plate 6 can be smoothly inserted into the tower body 1.

[0026] In this embodiment, the slot 17 is adapted to the corresponding mounting plate 8 to ensure that the mounting plate 8 is smoothly inserted into place.

[0027] In this embodiment, the fixing rod 21 is adapted to the corresponding socket 10 to ensure that the fixing rod 21 can be smoothly inserted into the corresponding socket 10.

[0028] In this embodiment, a vertically mounted electric push rod 22 is fixedly mounted on the outer wall of the tower body 1 above the sealing plate 16. The telescopic end of the electric push rod 22 faces downward, and a blind hole 23 adapted to the telescopic end of the electric push rod 22 is opened on the top of the corresponding sealing plate 16. The telescopic end of the electric push rod 22 is inserted into the corresponding blind hole 23, so that after the sealing plate 16 abuts against the tower body 1, the electric push rod 22 can be operated to extend its telescopic end and insert it into the blind hole 23, thereby locking the sealing plate 16 and ensuring the stability of the installation of the demister assembly 5 and the grid plate 6. When it is necessary to replace the demister assembly 55 and the grid plate 6, the electric push rod 22 can be operated first to retract its telescopic end and exit the blind hole 23, thereby releasing the locking of the sealing plate 16, and then the disassembly and replacement operation can be performed according to the aforementioned steps.

[0029] In this embodiment, the demister assembly 5 consists of a ridge demister 24 and two tubular demisters 25 distributed on the upper and lower sides of the ridge demister 24. This structure, which uses two types of demisters in combination, can more effectively improve the demisting effect and is more conducive to subsequent wet electrostatic precipitator operations. Both the ridge demister 24 and the tubular demisters 25 can be made using existing technologies.

[0030] In this embodiment, L-shaped insulating boxes 26 are provided on the outer sides of the tower body 1 at both the upper and lower ends on the left and right sides of the wet electrostatic precipitator 7. The conductive rod 27 of the cathode of the wet electrostatic precipitator 7 extends into the insulating box 26 and is fixed in the porcelain insulator 28 inside the insulating box 26 to ensure the conductivity and insulation of the wet electrostatic precipitator system, and to ensure the stable operation and safe operation of the equipment. The insulating box 26, conductive rod 27 and porcelain insulator 28 can all adopt existing technologies. A hollow air distribution plate 29 is provided on the inner wall of the insulating box 26 surrounding the porcelain insulator 28. Several air outlets 30 are opened on the inner side of the air distribution plate 29, and a hot air delivery pipe 31 is connected to the outer side of the air distribution plate 29. In actual use, hot air can be input into the air distribution plate 29 through the hot air delivery pipe 31 and evenly sprayed out through the air outlets 30 onto the periphery of the porcelain insulator 28. This allows for uniform and effective drying of the porcelain insulator 28, effectively preventing short circuits caused by condensation on the porcelain insulator 28 and ensuring the smooth operation of wet electrostatic precipitators. The hot air delivery pipe 31 can be connected to an existing conventional hot air dryer to provide the required drying hot air.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
