Description

Technical Field

[0001] This invention relates to the field of gas-liquid separation equipment technology, and specifically to a fiberglass C-type hook demister. Background Technology

[0002] Wet desulfurization is a technology that removes pollutants such as sulfur dioxide (SO2) from flue gas by reacting alkaline solutions or slurries with the flue gas, thereby reducing the pollution of the atmosphere caused by flue gas emissions.

[0003] In wet desulfurization, flue gas produces droplets after being scrubbed by the absorption tower. To ensure the safe operation of the equipment, these droplets must be removed. Commonly used demisting equipment includes cyclone demisters, ridge demisters, and horizontal demisters. Horizontal demisters consist of several horizontally arranged baffles fixed together by a frame, forming a baffle channel. As the flue gas passes through the baffle channel, lighter air passes through smoothly and is discharged, while heavier droplets and dust collide with the baffles to form droplets, which then converge and flow back into the desulfurization tower, thus reducing the possibility of air carrying impurities and causing atmospheric pollution.

[0004] However, during the demisting process, when the fan drives the flue gas through the demister, if the flue gas flows too fast, the pressure exerted by the flue gas on the demister baffle plate is too high, which can easily damage the demister. If the flow velocity is too low, the flue gas may not have enough inertia when it flows to the baffle plate, resulting in poor demisting effect. At the same time, dust and other impurities can easily adhere to the demister during long-term use, which can easily damage the demister or cause dust to be discharged into the air during the demisting process, thus causing a certain degree of atmospheric pollution. Summary of the Invention

[0005] In view of this, the purpose of this invention is to provide a fiberglass C-type hook demister to solve the problems of existing demisters. When the fan drives the flue gas through the demister, if the flue gas flows too fast, the pressure exerted by the flue gas on the demister's baffle plate is too high, easily damaging the demister. Conversely, if the flow velocity is too low, the flue gas may lack sufficient inertia when flowing to the baffle plate, resulting in poor demister performance. Furthermore, prolonged use of the demister can lead to the accumulation of dust and other impurities, causing damage or releasing dust into the air during the demister process, thus polluting the atmosphere.

[0006] This invention is achieved through the following technical solution:

[0007] A fiberglass C-type hook demister includes a support frame, baffles, and a drive unit. The support frame is fixed to the outlet end of the absorption tower. There are multiple baffles arranged at intervals along the length of the support frame. The upper edge of the baffle plate is rotatably connected to the support frame with the length of the baffle plate as the rotation center. The drive unit is used to drive the rotation of the baffle plates.

[0008] Furthermore, the upper edge of the baffle plate is provided with a rotating shaft along the length direction, and the support frame is recessed inward to form a rotating groove corresponding to the position of the baffle plate, and the rotating shaft is rotatably fitted into the rotating groove.

[0009] Furthermore, the drive unit includes connecting rods, racks, and an adjustment unit. There are multiple connecting rods, one end of which is connected to a rotating shaft and the other end is hinged to the rack. The rack is connected to the adjustment unit, which is used to adjust the movement of the rack.

[0010] Furthermore, the adjusting part includes a rotating rod, a fan blade, a gear, and a spring. The upper end of the rotating rod is connected to the fan blade, and the lower end is connected to the support frame. The gear is connected to the middle of the rotating rod and meshes with the rack. The two ends of the spring are respectively connected to the absorption tower and one end of the rack.

[0011] Furthermore, it also includes a cleaning unit, of which there are two, which are respectively located on both sides of the support frame, and both cleaning units can be movably connected to the baffle plate along the length of the baffle plate.

[0012] Furthermore, the cleaning unit includes a cleaning brush, a reciprocating screw, a dual-axis motor, and a connecting rod. There are multiple cleaning brushes, with the lower ends of each brush corresponding to the two sides of multiple baffles, and the upper ends rotatably connected to the connecting rod. The reciprocating screw is arranged in a direction parallel to the baffles, and its two reciprocating ends are respectively connected to the output end of the dual-axis motor and the connecting rod.

[0013] Furthermore, the support frame is connected to a flexible switch, which can rotate parallel to the length direction of the baffle plate as a rotation axis. The rotating rod is connected to a cam, and the protruding part of the cam abuts against one end of the flexible switch. The flexible switch is used to control the rapid rotation of the dual-axis motor.

[0014] Furthermore, the cleaning unit also includes a cleaning tank, a water tank, and nozzles. The cleaning tank is connected to the outer wall of the absorption tower, and the water tank is equipped with multiple nozzles, each corresponding to a cleaning brush.

[0015] Furthermore, the cleaning unit also includes a small axial flow pump, a recovery tank, and a filter screen. The recovery tank is connected to the cleaning tank, the filter screen is located between the recovery tank and the cleaning tank, the small axial flow pump is installed inside the recovery tank, and the output end of the small axial flow pump is connected to a water tank.

[0016] Furthermore, the cleaning unit also includes a first bevel gear and a second bevel gear. The first bevel gear is connected to one end of the reciprocating screw, and the second bevel gear is connected to the pump shaft of the small axial flow pump. The first bevel gear and the second bevel gear mesh.

[0017] The beneficial effects of this invention are as follows:

[0018] 1. By dynamically adjusting the rotation angle of the baffle plate through the drive unit, the baffle plate achieves a dynamic balance when demisting the flue gas. This ensures the efficiency of the demister in demisting the flue gas while reducing the possibility of excessive flue gas pressure on the baffle plate, which could lead to damage. This, to a certain extent, guarantees the service life of the demister and reduces the possibility of damage to the absorption tower.

[0019] 2. The cleaning unit cleans the baffles, reducing the likelihood of air carrying away dust accumulated on them, further minimizing the possibility of exhaust air pollution. Simultaneously, the cleaning unit works in conjunction with the drive unit to adapt to changing operating conditions, balancing airflow speed and cleaning speed, and avoiding over-design.

[0027] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0028] Please see Figure 1-5 This invention provides a technical solution for a fiberglass C-type hook demister: a fiberglass C-type hook demister includes a support frame 1, baffles 2, and a drive unit 3. The support frame 1 is fixed to the outlet end of the absorption tower 5. There are multiple baffles 2, and the multiple baffles 2 are arranged at intervals along the length direction of the support frame 1. The upper edge of the baffles 2 is rotatably connected to the support frame 1 with the length direction of the baffles 2 as the rotation center. The drive unit 3 is used to drive the rotation of the baffles 2.

[0029] When using the C-type hook demister of the present invention to demist flue gas, the support frame 1 is first installed at the outlet of the absorption tower 5. Since the upper edge of the baffle plate 2 is rotatably connected to the support frame 1 with the length direction of the baffle plate 2 as the rotation center, the angle between the baffle plate 2 and the support frame 1 can be adjusted when the flue gas passes through.

[0030] In the initial position, multiple baffles 2 are arranged parallel to each other and at a certain angle to the vertical plane. At this time, the minimum gap between two adjacent baffles 2 is the smallest, and the velocity of the flue gas passing through the baffles 2 is the largest. When the flue gas flow rate increases, the flow rate of the flue gas through the baffles 2 also increases, and the flow velocity through the baffles 2 increases. At this time, the drive unit 3 drives the baffles 2 to rotate, which increases the minimum gap between two adjacent baffles 2, thereby reducing the pressure on the baffles 2 when the flue gas passes through the baffles 2, thus reducing the possibility of the baffles 2 being easily damaged due to excessive pressure over a long period of time. When the flue gas flow rate is small, the drive unit 3 drives the baffles 2 to rotate again, which reduces the minimum gap between the baffles 2, thereby increasing the contact area between the baffles 2 and the flue gas, and also increasing the baffles 2's resistance to water mist in the flue gas, thereby increasing the demisting efficiency of the demister, increasing the cleanliness of the exhaust gas to a certain extent, and reducing the pollution of the exhaust gas to the atmosphere.

[0031] With this structure, the dynamic adjustment of the rotation angle of the baffle plate 2 by the drive unit 3 enables the baffle plate 2 to achieve a dynamic balance when demisting the flue gas. This ensures the efficiency of the demister in demisting the flue gas while reducing the possibility of damage to the baffle plate 2 due to excessive flue gas pressure. To a certain extent, this ensures the service life of the demister and reduces the possibility of damage to the absorption tower 5.

[0032] In this embodiment: the upper edge of the baffle plate 2 is provided with a rotating shaft 21 along the length direction, and the support frame 1 is recessed inward to form a rotating groove 11 corresponding to the position of the baffle plate 2, and the rotating shaft 21 is rotatably fitted into the rotating groove 11.

[0033] With this structure, the upper edge of the baffle 2 can be rotatably connected to the support frame 1 with the length direction of the baffle 2 as the rotation center.

[0034] In this embodiment: the driving unit 3 includes a connecting rod 31, a rack 32 and an adjusting unit. There are multiple connecting rods 31. One end of each connecting rod 31 is connected to the rotating shaft 21, and the other end is hinged to the rack 32. The rack 32 is connected to the adjusting unit, and the adjusting unit is used to adjust the movement of the rack 32.

[0035] When the adjusting unit adjusts the movement of the rack 32, it drives the connecting rod 31 to make a circular motion around one end of the connecting rod 31 as the center, thereby driving the rotating shaft 21 to rotate with the one end of the connecting rod 31. The rotation of the rotating shaft 21 drives the baffle plate 2 to rotate around the center line of the rotating shaft 21 as the center of rotation, thereby changing the distance of the minimum gap between two adjacent baffle plates 2. Since one end of the multiple connecting rods 31 is connected to the rotating shaft 21 in a one-to-one correspondence and the other end is hinged to the rack 32, the rotation angle of the baffle plate 2 can be adjusted simultaneously.

[0036] In this embodiment: the adjustment part includes a rotating rod 33, a fan blade 34, a gear 35 and a spring 36. The upper end of the rotating rod 33 is connected to the fan blade 34 and the lower end is connected to the support frame 1. The gear 35 is connected to the middle of the rotating rod 33 and meshes with the rack 32. The two ends of the spring 36 are respectively connected to the absorption tower 5 and one end of the rack 32.

[0037] When the flue gas flows too fast through the demister, the thrust of the flue gas flow will drive the fan blade 34 to rotate. The rotation of the fan blade 34 will drive the gear 35 to rotate, which will in turn drive the rack 32 to move. Since the two ends of the spring 36 are respectively connected to the absorption tower 5 and one end of the rack 32, the movement of the rack 32 will cause the spring 36 to be compressed or stretched, and the rotation angle of the fan blade 34 will be limited by the spring 36.

[0038] When the gas flow rate of the flue gas after passing through the demister is low, the restoring deformation force of the spring 36 will drive the fan to rotate at a certain angle so that the flue gas flow rate reaches a certain equilibrium state. When the flue gas flow rate is too fast, it will further drive the fan blade 34 to rotate. In this way, the rotation angle of the fan blade 34 is maintained at a suitable state.

[0039] Specifically, the gear 35 is slidably connected to the rotating rod 33, and the upper and lower end faces of the rack 32 are both connected to abutment plates. The abutment plates abut against the upper and lower end faces of the gear 35. With this structure, the rack 32 will not disengage from the meshing area with the gear 35.

[0040] In this embodiment, a cleaning section 4 is also included. There are two cleaning sections 4, which are respectively located on both sides of the support frame 1. Both cleaning sections 4 can be movably connected to the baffle plate 2 along the length direction of the baffle plate 2.

[0041] By moving along the length of the baffle plate 2, the two cleaning sections 4 clean the dust and other impurities remaining on the baffle plate 2 on both sides of the support frame 1, reducing the possibility that the impurities on the baffle plate 2 will be carried out again and discharged when the flue gas flows, thus reducing the possibility of the discharged gas polluting the atmosphere to a certain extent.

[0042] In this embodiment: the cleaning unit 4 includes a cleaning brush 41, a reciprocating screw 42, a dual-axis motor 43, and a connecting rod 44. There are multiple cleaning brushes 41, with the lower ends of the multiple cleaning brushes 41 correspondingly abutting against the two sides of multiple baffles 2, and the upper ends rotatably connected to the connecting rod 44. The reciprocating screw 42 is arranged in a direction parallel to the baffles 2, and the two ends of the reciprocating screw are respectively connected to the output end of the dual-axis motor 43 and the connecting rod 44.

[0043] Start the dual-axis motor 43, which drives the reciprocating screw 42 to rotate, thereby driving the cleaning brush 41 to move back and forth along the length of the baffle 2. With this structure, the cleaning part 4 can clean the dust on the baffle 2.

[0044] In this embodiment: the support frame 1 is connected to an elastic switch 12, which can rotate parallel to the length direction of the baffle plate 2 as a rotating shaft 21. The rotating rod 33 is connected to a cam 13, and the protruding part of the cam 13 abuts against one end of the elastic switch 12. The elastic switch 12 is used to control the dual-axis motor 43 to rotate rapidly.

[0045] Since the rotating rod 33 is connected to the cam 13, when the fan drives the rotating rod 33 to rotate, it can drive the cam 13 to rotate. When the flue gas speed is slow, the angle at which the flue gas drives the fan to rotate is small, thus driving the cam 13 to rotate at a small angle. At this time, the cam 13 is insufficient to push the elastic switch 12 to open. At this time, the motor speed is slow, and the cleaning brush 41 cleans the dust slowly. When the flue gas speed increases, the angle at which the fan rotates increases, thus causing the cam 13 to rotate and push the elastic switch 12 to open, causing the motor to rotate quickly and driving the cleaning brush 41 to move quickly. This allows the cleaning brush 41 to better clean the baffle 2 when the flue gas volume increases. With this structure, the cleaning brush 41 can adjust its speed according to the flue gas volume, which ensures the cleaning effect to a certain extent.

[0046] In this embodiment: the cleaning unit 4 further includes a cleaning trough 45, a water tank 46 and a nozzle 47. The cleaning trough 45 is connected to the outer wall of the absorption tower 5. The water tank 46 is provided with a plurality of nozzles 47, and the plurality of nozzles 47 are arranged one by one to the cleaning brush 41.

[0047] When the cleaning brush 41 moves to the side wall of the absorption tower 5, the water in the water tank 46 of the nozzle 47 cleans the cleaning brush 41 through the nozzle 47. The sewage after cleaning the cleaning brush 41 flows into the cleaning tank 45 for collection. With this structure, the nozzle 47 can clean the cleaning brush 41, which reduces the possibility that the dust adhering to the cleaning brush 41 will be carried back to the baffle plate 2 to a certain extent.

[0048] In this embodiment: the cleaning unit 4 further includes a small axial flow pump 48, a recycling tank 49 and a filter screen 40. The recycling tank 49 is connected to the cleaning tank 45. The filter screen 40 is located between the recycling tank 49 and the cleaning tank 45. The small axial flow pump 48 is installed in the recycling tank 49. The output end of the small axial flow pump 48 is connected to the water tank 46.

[0049] Wastewater in the cleaning tank 45 is filtered through the filter screen 40 and enters the recycling tank 49. The small axial flow pump 48 draws water from the recycling tank 49 into the water tank 46 and then uses it to clean the cleaning brush 41. This structure realizes water circulation and saves water resources to a certain extent.

[0050] In this embodiment: the cleaning part 4 further includes a first bevel gear 481 and a second bevel gear 482. The first bevel gear 481 is connected to one end of the reciprocating screw 42, and the second bevel gear 482 is connected to the pump shaft of the small axial flow pump 48. The first bevel gear 481 and the second bevel gear 482 mesh.

[0051] The reciprocating screw 42 rotates, driving the cleaning brush 41 to move back and forth, while simultaneously driving the first bevel gear 481 to rotate. The rotation of the first bevel gear 481 drives the second bevel gear 482 to rotate, and the rotation of the second rotary gear 35 drives the pump shaft of the small axial flow pump 48 to rotate, drawing water from the recycling box 49 into the water tank 46. With this structure, water circulation can be achieved without additional power, saving energy to a certain extent.

Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention.
