Description

Technical Field

[0001] This utility model belongs to the field of demister technology, and in particular relates to a demister device for a desulfurization absorption tower. Background Technology

[0002] Demisters operate on the principle of inertia and gravity acting on liquid droplets in flue gas. When flue gas containing droplets passes through the demister channel at a certain speed, the curved structure of the channel forces the flue gas to continuously change direction during its movement. This causes gas-liquid separation under the influence of inertial and centrifugal forces. Some droplets are thrown off and, as they accumulate to a certain extent, move downwards into the scrubbing tank under the influence of gravity. Meanwhile, the solid matter remaining on the demister blades is recovered into the scrubbing tank by the flushing liquid. A search revealed that patent application number 202421193290.1 ​​discloses a demister device suitable for desulfurization absorption towers, relating to the field of demister technology. The device includes a fixed frame, baffle blades, and a descaling assembly. The fixed frame contains baffle blades, and multiple sets of baffle blades are detachably installed at both ends from the fixed frame. The descaling assembly is detachably installed from the baffle blades. The descaling assembly includes end plates, a sliding rod, a connecting seat, a first descaling scraper, and a second descaling scraper. A sliding rod is provided between the two end plates. The first and second descaling scrapers are respectively located on both sides of the baffle blades, and the upper ends of the first and second descaling scrapers are respectively connected to the lower sides of the connecting seat.

[0003] However, during actual use, the applicant found that the baffle blades are fixed to the fixed frame by connecting bolts. When it is necessary to replace the first and second descaling scrapers worn on both sides of the baffle blades, since the first and second descaling scrapers cannot be directly removed from between the two adjacent baffle blades, it is necessary for personnel to disassemble and remove all the baffle blades one by one from the fixed frame. This requires personnel to disassemble multiple bolts, which is not convenient. In view of this, we propose a demisting device for desulfurization absorption tower. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 As shown, this utility model provides a technical solution:

[0022] A demisting device for a desulfurization absorption tower includes a U-shaped frame 1. A movable plate 3 is movably connected to the front side of the U-shaped frame 1 via a screw 2. Guide grooves 11 are symmetrically arranged on the front side of the U-shaped frame 1. Guide sliders 31 are symmetrically arranged on the rear side of the movable plate 3, and the guide sliders 31 slide along the guide grooves 11 to guide the movable plate 3, allowing it to move back and forth along the guide grooves 11 under the drive of the screw 2. The front end of the screw 2 is threaded into the guide slider 31. A drive box 8 is fixedly installed on the rear side of the U-shaped frame 1. The rear end of the screw 2 extends into the drive box 8 and is fitted with a worm gear 81. A worm 82 is rotatably connected to the drive box 8 above the worm gear 81 via a bearing. One end of the worm 82 extends to the outside of the drive box 8 and is fixedly installed with an adjusting handle 821. The worm gear 81 and the worm 82 are connected by a transmission mechanism. Baffle blades 4 are installed side-by-side at equal intervals between frame 1 and movable plate 3. Limiting slots 5 for holding the ends of baffle blades 4 are also installed side-by-side at equal intervals on the inner wall of U-shaped frame 1 and the rear side of movable plate 3. A first descaling scraper 9 is slidably connected to one side of baffle blade 4, and a second descaling scraper 10 is slidably connected to the other side of baffle blade 4. The upper ends of the first descaling scraper 9 and the second descaling scraper 10 are fixedly connected by connecting support 7. The upper ends of the first descaling scraper 9 and the second descaling scraper 10 are fixed to the two sides of the connecting support 7 by second bolts 71. By driving the movable plate 3 forward by the drive screw 2, the baffle blades 4 can be removed from between U-shaped frame 1 and movable plate 3 without disassembling multiple connecting bolts, thus facilitating the quick replacement of worn first descaling scraper 9 and second descaling scraper 10.

[0023] The connecting supports 7 are fixedly connected by connecting beams 6. The connecting beams 6 are fixed to the connecting supports 7 by first bolts 61. The lower end of the first bolts 61 passes through the connecting beams 6 and is screwed into the threaded hole at the top of the connecting supports 7. Connecting grooves 72 are symmetrically provided on the front and rear sides of the connecting supports 7. Connecting protrusions 63 are symmetrically provided on both sides inside the connecting beams 6. The connecting protrusions 63 are connected with the connecting grooves 72, so that the connecting beams 6 can better drive the connecting supports 7 to move back and forth. A handle 62 is fixedly provided on the front side of the connecting beams 6. Multiple connecting supports 7 are connected by the connecting beams 6. By pushing and pulling the connecting beams 6, multiple connecting supports 7 can be moved back and forth synchronously, thereby driving multiple sets of first descaling scrapers 9 and second descaling scrapers 10 to move synchronously, improving the descaling efficiency on the surface of the deflecting blades 4.

[0024] Working Principle: During operation, when the demister is demisting, the flue gas flows upward through the demister. As the flue gas flows between the baffle blades 4, it is acted upon by the baffle blades 4. The liquid droplets carried in the flue gas are captured and move downwards to the scrubbing tank under the action of gravity. When it is necessary to treat the scale buildup on the baffle blades 4, the connecting beam 6 is pushed by holding the handle 62, which causes the connecting support 7 to slide along the top of the baffle blades 4. This causes the first descaling scraper 9 and the second descaling scraper 10 to slide along the side wall of the baffle blades 4. The first descaling scraper 9 and the second descaling scraper 10, which are attached to the side wall of the baffle blades 4, will scrape off the scale on the baffle blades 4. The fallen scale will also enter the scrubbing tank. After a period of time, when it is necessary to repair the worn first descaling scraper... When replacing the first descaling scraper 9 and the second descaling scraper 10, the adjusting handle 821 can be manually rotated counterclockwise to drive the worm gear 82 to rotate. The rotation of the worm gear 82 can drive the worm wheel 81 to rotate together with the screw 2. The rotation of the screw 2 can drive the movable plate 3 to move forward along the guide groove 11, thereby increasing the distance between the U-shaped frame 1 and the movable plate 3, and making the distance between the U-shaped frame 1 and the limiting slot 5 on the movable plate 3 greater than the length of the baffle blade 4. At this time, the connecting beam 6 can be pulled upward, and the first descaling scraper 9 and the second descaling scraper 10 can be moved out through the connecting support 7. Finally, the second bolt 71 at the upper end of the first descaling scraper 9 and the second descaling scraper 10 can be unscrewed, and the first descaling scraper 9 and the second descaling scraper 10 can be removed from the connecting support 7 for replacement.
