Description

Technical Field

[0001] This utility model relates to the field of tube bundle demister technology, and in particular to a tube bundle demister device. Background Technology

[0002] Tube bundle demisters are devices used for industrial waste gas treatment, primarily for removing mist droplets and particulate matter from gases. They are widely used in industries such as chemical, power, and metallurgy. Their core design, through optimized tube bundle structure and materials, significantly improves demister efficiency and durability. Tube bundle demisters primarily utilize the mechanism of collisions between fine mist droplets and dust particles in flue gas for purification. The specific steps include: flue gas enters the upper part of the absorption tower, where it is in a low-temperature saturated state or contains a large number of fine mist droplets. Under airflow conditions, the droplets collide with dust particles and agglomerate into larger particles. These agglomerated particles are then thrown against the inner wall of the tube under centrifugal force and eventually flow back to the bottom of the absorption tower.

[0003] However, when using tube bundle demisters, if the slurry contains excessive gypsum, limestone or other impurities, it is very easy for them to crystallize and deposit on the surface of the tube bundle, which may lead to blockage. This will result in a reduction in the flow area, an abnormal increase in flue gas velocity, and a decrease in demister efficiency, thus affecting the demister effect.

[0004] In view of this, this paper studies and improves the existing problems, and provides a tube bundle demisting device, aiming to solve the problems and improve the practical value through this technology. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model uses the rotation of a fan to drive the rotation of a large gear, which in turn drives the rotation of a small gear, which in turn drives the reciprocating screw to rotate inside a rectangular groove. This causes the slider to move the liquid storage frame up and down. During the movement, the first trapezoidal block moves towards the position of the liquid storage frame under the action of the squeezing block.

[0013] 2. In this utility model, as the liquid storage frame moves, the scraper moves along with it, thereby cleaning the dissolved dirt off. When the scraper moves, the sponge strip also moves along with it, thereby cleaning the water mist remaining on the inner wall of the pipe. At the same time, under the action of the second trapezoidal block and the squeezing block, the water inside the sponge strip can be squeezed out. Attached Figure Description

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Therefore, the following detailed description of the embodiments of this utility model provided in the drawings is not intended to limit the scope of the claimed utility model, but merely to illustrate selected embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0017] See Figures 1 to 4 As shown, this utility model provides a tube bundle demisting device, including a pipe 1, a baffle 4 fixedly connected to the inner wall of the pipe 1, a motor 2 fixedly connected to one side of the baffle 4, a fan 3 provided on the other side of the baffle 4, the fan 3 being driven by the motor 2, a large gear 5 fixedly connected to one end of the fan 3, a groove 6 opened in the inner wall of the pipe 1, a small gear 7 rotatably connected to the inner wall of the groove 6, a rectangular groove 8 opened in the inner wall of the pipe 1, a reciprocating screw 9 rotatably connected inside the rectangular groove 8, the reciprocating screw 9 being fixedly connected to the bottom of the small gear 7, a slider threadedly connected to the surface of the reciprocating screw 9, a liquid storage frame 12 fixedly connected to the side of the slider, a push plate 14 provided inside the liquid storage frame 12, a slide rod fixedly connected to the side of the push plate 14, a first trapezoidal block 15 fixedly connected to one end of the slide rod, a fixing frame 10 fixedly connected inside the pipe 1, a squeezing block 11 fixedly connected to the surface of the fixing frame 10, a first spring 16 sleeved on the surface of the slide rod, and a sponge block 13 fixedly connected to the side of the liquid storage frame 12 near the inner wall of the pipe 1. A fixed rod is fixedly connected to the top of the liquid storage frame 12, a scraper 17 is fixedly connected to the side of the fixed rod, a bracket 18 is fixedly connected to the bottom of the fixed rod, a round rod is slidably connected to the side of the bracket 18, an arc plate 19 is fixedly connected to one end of the round rod, a sponge strip is fixedly connected to the side of the arc plate 19, a second trapezoidal block 20 is fixedly connected to the other end of the round rod, and a second spring 21 is sleeved on the surface of the round rod. The two ends of the first spring 16 are fixedly connected to the side of the liquid storage frame 12 and the side of the first trapezoidal block 15, respectively, and the two ends of the second spring 21 are fixedly connected to the side of the bracket 18 and the side of the second trapezoidal block 20, respectively.

[0018] It should be noted that after pipe 1 is installed, motor 2 is started, causing fan 3 to rotate, which in turn drives large gear 5 to rotate. Under the meshing transmission of the gears, small gear 7 rotates inside groove 6, which in turn drives reciprocating screw 9 to rotate inside rectangular groove 8. This causes liquid storage frame 12 to move along the surface of reciprocating screw 9 with slider. When first trapezoidal block 15 contacts extrusion block 11, slide rod moves into liquid storage frame 12, which in turn pushes push plate 14 towards the inner wall of pipe 1. This allows the liquid inside liquid storage frame 12 to be applied to the inner wall of pipe 1 through sponge block 13. The reaction process dissolves the dirt on the inner wall of pipe 1. After the first trapezoidal block 15 separates from the squeezing block 11, the slide bar resets under the action of the first spring 16. As the liquid storage frame 12 moves downward, the scraper 17 moves downward with the liquid storage frame 12, thereby cleaning the dissolved dirt off the inner wall of pipe 1. At the same time, it also moves the sponge strip, thereby cleaning the liquid on the inner wall of pipe 1. When the second trapezoidal block 20 contacts the squeezing block 11, the round rod moves towards the inner wall of pipe 1, thereby squeezing the sponge strip through the arc plate 19, thereby squeezing out the liquid inside the sponge strip.

[0019] See Figures 1 to 4 As shown, scraper 17 is made of stainless steel and is attached to the inner wall of pipe 1.

[0020] It should be noted that because the scraper 17 is made of stainless steel, the scraper 17 will not rust on the inner wall of the pipe 1, thus avoiding the phenomenon of the scraper 17 and the pipe 1 rusting together.

[0021] See Figures 1 to 4 As shown, the sponge strip is attached to the inner wall of pipe 1, and the sponge block 13 is attached to the inner wall of pipe 1.

[0022] It should be noted that the sponge strip can absorb the water mist on the inner wall of pipe 1, thereby keeping the inner wall of pipe 1 dry. The sponge block 13 can evenly coat the solution inside the liquid storage frame 12 onto the inner wall of pipe 1, thereby completely dissolving the dirt on the inner wall of pipe 1.

[0023] See Figures 1 to 4 As shown, multiple extrusion blocks 11 are evenly arranged on the side of the support 18. The distance between the multiple extrusion blocks 11 is the same. The extrusion blocks 11 are made of rubber material. The first trapezoidal block 15 and the second trapezoidal block 20 are also made of rubber material.

[0024] It should be noted that because multiple extrusion blocks 11 are provided, the solution can be applied to the inner wall of the pipe 1 multiple times through the sponge block 13 when the liquid storage frame 12 moves down. Since the extrusion block 11, the second trapezoidal block 20 and the first trapezoidal block 15 are all made of rubber, there will be no rigid collision, thus avoiding damage.

[0025] See Figures 1 to 4 As shown, the push plate 14 is made of plastic material, and the bracket 18 is made of rigid plastic material.

[0026] Working principle: After the pipe 1 is installed, the motor 2 is started, causing the fan 3 to rotate, which in turn drives the large gear 5 to rotate. Under the meshing transmission of the gears, the small gear 7 rotates inside the groove 6, which in turn drives the reciprocating screw 9 to rotate inside the rectangular groove 8. This causes the liquid storage frame 12 to move along the surface of the reciprocating screw 9 with the slider. When the first trapezoidal block 15 contacts the extrusion block 11, the slider moves into the liquid storage frame 12, which in turn pushes the push plate 14 towards the inner wall of the pipe 1. This allows the liquid inside the liquid storage frame 12 to be applied to the inner wall of the pipe 1 through the sponge block 13, thereby reacting with and dissolving the dirt on the inner wall of the pipe 1. When the first trapezoidal block 15 separates from the extrusion block 11, the slider, under the action of the first spring 16... During the resetting process, as the liquid storage frame 12 moves downward, the scraper 17 moves downward along with the liquid storage frame 12, thereby cleaning the dissolved dirt from the inner wall of the pipe 1. Because the scraper 17 is made of stainless steel, it will not rust on the inner wall of the pipe 1, thus avoiding the phenomenon of the scraper 17 and the pipe 1 corroding together. At the same time, it also drives the sponge strip to move, thereby cleaning the liquid on the inner wall of the pipe 1. When the second trapezoidal block 20 contacts the squeezing block 11, the round rod moves towards the inner wall of the pipe 1, thereby squeezing the sponge strip through the arc plate 19, thereby squeezing out the liquid inside the sponge strip. Because multiple squeezing blocks 11 are provided, the solution can be applied to the inner wall of the pipe 1 multiple times through the sponge block 13 when the liquid storage frame 12 moves downward.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. 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.
