This allows the multiple intercepting rods, in conjunction with the top ring, to move the fiber cotton. When the top ring and multiple intercepting rods have all moved to the position of being inserted into the mesh cylinder, the threaded cylinder is manually rotated, causing the threaded cylinder to connect to the surface of the threaded ring through rotation, thus achieving the assembly and fixation between the fiber cotton and the mesh cylinder. Furthermore, the fiber cotton can be disassembled and replaced separately in the later stages, reducing material waste caused by personnel replacing the fiber cotton later and improving the convenience and efficiency of personnel maintaining the demister body.

[0028] The present invention will be described below with specific embodiments, but these are not intended to limit the scope of the invention.
[0029] Example 1
[0030] Figures 1-5 The fiber demister and its desulfurization device shown include a demister body 2 installed inside a desulfurization tower 1. The demister body 2 is divided into a top plate 21 and a mesh cylinder 22. The top plate 21 is fixedly connected to the mesh cylinder 22. A connecting device 4 is provided on one side of the demister body 2, and a cleaning device 3 is provided on the other side. The connecting device 4 includes a threaded ring 41, which is fixedly connected to the mesh cylinder 22. A threaded cylinder 42 is threadedly connected to the surface of the threaded ring 41. Multiple intercepting rods 43 are fixedly connected to the inner wall of the threaded cylinder 42. A top ring 44 is fixedly connected to the end of the multiple intercepting rods 43 away from the threaded cylinder 42. Fiber cotton 48 is snapped between the multiple intercepting rods 43. The surface of the top ring 44 is slidably connected to the inner wall of the mesh cylinder 22. By setting the connecting device 4, the first step is to manually... The fiber cotton 48 is inserted into the inner position of multiple intercepting rods 43 and top ring 44. At this time, the threaded cylinder 42 is manually moved, causing the threaded cylinder 42 to drive the multiple intercepting rods 43 to move, which in turn drives the top ring 44 to move. The multiple intercepting rods 43, in conjunction with the top ring 44, drive the fiber cotton 48 to move. When the top ring 44 and multiple intercepting rods 43 have all moved to the position of being inserted into the mesh cylinder 22, the threaded cylinder 42 is manually rotated, so that the threaded cylinder 42 is connected to the surface of the threaded ring 41 through rotation, thereby achieving the assembly and fixation between the fiber cotton 48 and the mesh cylinder 22. At the same time, the fiber cotton 48 can be disassembled and replaced separately in the later stage, reducing the material waste caused by personnel replacing the fiber cotton 48 in the later stage, and improving the convenience and efficiency of personnel maintenance of the demister body 2.
[0031] Example 2
[0032] Figure 3 and Figure 4A handle 47 is fixedly connected to the side of the threaded cylinder 42 away from the interceptor bar 43. The inner side of the handle 47 is provided with multiple anti-slip protrusions. By setting the handle 47, the handle 47 can provide a point of leverage for the personnel, so that the personnel can easily insert and remove the threaded cylinder 42 and the fiber cotton 48 by manually moving the handle 47. Multiple anti-slip strips 46 are fixedly connected to the surface of the threaded cylinder 42. The multiple anti-slip strips 46 are arranged at equal intervals. By setting the anti-slip strips 46, the anti-slip strips 46 can increase the friction between the hand and the surface of the threaded cylinder 42, reducing the possibility of the hand slipping when the personnel rotate the threaded cylinder 42.
[0033] Figure 3 and Figure 4 A rubber pad 45 is fixedly connected to one side of the top ring 44 shown. The rubber pad 45 completely covers the surface of the top ring 44. By setting the rubber pad 45, the rubber pad 45 can fill the gap between the top ring 44 and the net cylinder 22, improve the fit between the two, and reduce the shaking of the top ring 44 and the intercepting rod 43 inside the net cylinder 22.
[0034] Example 3
[0035] Figure 4 and Figure 5 The cleaning device 3 shown includes a motor 31, which is fixedly connected to the screen cylinder 22. A screw 32 is fixedly connected to the output end of the motor 31. A screw hole block 35 is threadedly connected to the surface of the screw 32. A ring 36 is fixedly connected to one side of the screw hole block 35. The ring 36 is fitted onto the surface of the screen cylinder 22. An annular brush 37 is fixedly connected to the inner wall of the ring 36. The surface of the annular brush 37 is in contact with the surface of the screen cylinder 22. By setting up the cleaning device 3, the motor 31 is first started, which drives the screw 32 to rotate. The screw 32 drives the screw hole block 35 to move up and down, which in turn drives the ring 36 to move up and down along the surface of the screen cylinder 22. The ring 36 then drives the annular brush 37 to move up and down along the surface of the screen cylinder 22 and scrapes off the impurities adhering to the surface of the screen cylinder 22. This achieves rapid cleaning of the surface of the screen cylinder 22, reduces the amount of dust or impurities adhering to the surface of the screen cylinder 22, and prevents blockage of the screen cylinder 22, which would affect the normal entry of flue gas. This improves the convenience and efficiency of cleaning the surface of the screen cylinder 22.
[0036] Figure 4 and Figure 5A support block 33 is fixedly connected to the side of the mesh cylinder 22 away from the motor 31. The end of the screw 32 away from the motor 31 is rotatably connected to the support block 33 through a bearing. By setting the support block 33, the support block 33, in conjunction with the bearing, can support and reinforce the side of the screw 32 away from the motor 31, reducing the wobbling of the screw 32 during use. A positioning rod 34 is fixedly connected to the side of the mesh cylinder 22 away from the motor 31. A circular hole block 38 is fixedly connected to the side of the ring 36 away from the screw hole block 35. The surface of the positioning rod 34 is slidably connected to the inner wall of the circular hole block 38. By setting the positioning rod 34, the positioning rod 34 can be located inside the circular hole block 38 to limit the ring 36 and the annular brush 37, reducing the wobbling of the ring 36 and the annular brush 37 during use.
[0037] Working principle: First, the screen cylinder 22 is installed in the desulfurization tower 1 near the top through the top plate 21. When the gas containing mist particles passes through the inside of the screen cylinder 22, the mist particles will be captured on the fiber layer set inside the screen cylinder 22 through inertial collision, direct interception and Brownian motion. They will gradually condense into large particles or liquid films. Then, under the action of the airflow, the particles or liquid films will pass through the fiber layer and be discharged, thereby achieving the function of capturing mist and purifying gas.
[0038] First, manually insert the fiber cotton 48 into the inner position of the multiple intercepting rods 43 and the top ring 44. Then, manually move the threaded cylinder 42, so that the threaded cylinder 42 drives the multiple intercepting rods 43 to move, which in turn drives the top ring 44 to move. This allows the multiple intercepting rods 43 to work with the top ring 44 to move the fiber cotton 48. When the top ring 44 and the multiple intercepting rods 43 have all moved to the position inside the mesh cylinder 22, manually rotate the threaded cylinder 42 so that the threaded cylinder 42 is connected to the surface of the threaded ring 41 through rotation, thus achieving the assembly and fixation between the fiber cotton 48 and the mesh cylinder 22. At the same time, the fiber cotton 48 can be disassembled and replaced separately later.
[0039] First, start the motor 31, which drives the screw 32 to rotate. The screw 32 then drives the screw hole block 35 to move up and down, which in turn drives the ring 36 to move up and down along the surface of the mesh cylinder 22. The ring 36 then drives the annular brush 37 to move up and down along the surface of the mesh cylinder 22 and scrape off the impurities adhering to the surface of the mesh cylinder 22, thus achieving rapid cleaning of the surface of the mesh cylinder 22.
