Description

Technical Field

[0001] This utility model relates to the technical field of waste gas treatment equipment, and in particular, to a treatment tower for waste gas scrubbing. Background Technology

[0002] Industrial waste gas requires treatment before discharge. Typically, this waste gas contains dust particles and toxic gases. Dust particle removal is generally achieved using a scrubbing tower, also known as a spray tower. Sprayers are installed at the top of the scrubbing tower. During operation, dust-laden waste gas enters the tower from the bottom, and the sprayers at the top spray washing liquid. The rising waste gas and the descending spray form a counter-current contact. During this process, dust particles in the waste gas are captured by the mist droplets and flow with them to the bottom of the tower for discharge. The washed gas then exits from the top. Currently, in most commercially available waste gas scrubbing towers, the nozzle positions are fixed. The nozzle position directly determines the spray range within the tower. Once the nozzle position is locked, the spray range within the tower is also fixed. This results in insufficient contact between the waste gas and the spray water in the space corresponding to the nozzle, leading to poor scrubbing efficiency. Therefore, the inventors need to improve the structure of the waste gas scrubbing tower to solve the above problems. Utility Model Content

[0021] The present invention will now be described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0022] Please see Figures 1-5 This utility model provides a treatment tower for waste gas scrubbing, including a tower body 10, a tower cover 20, and a spray assembly 30. The tower cover 20 is rotatably mounted on the tower body 20, and the spray assembly 30 is installed inside the tower cover 20 and is slidable relative to the tower cover 20. A first driving member 40 is installed on the tower body 10, and a second driving member 50 is installed on the tower cover 20. The first driving member 40 is used to drive the tower cover 20 to rotate relative to the tower body 20, and the second driving member 50 is used to drive the spray assembly 30 to slide relative to the tower cover 20.

[0023] The tower body 10 has a cylindrical structure with both ends open. An air inlet pipe 11 is connected to the side wall of the tower body 10. The air inlet pipe 11 passes through the side wall of the tower body 10, and the part of the air inlet pipe 11 located inside the tower body 10 is bent upward so that the central axis of the smoke outlet of the air inlet pipe 11 is arranged longitudinally and is coaxial with the central axis of the tower body 10.

[0024] The tower cover 20 has an arc-shaped cover structure with an opening at the lower end. The tower cover 20 includes a straight cylindrical section 21 and a hemispherical shell 22. The straight cylindrical section 21 is fixedly connected to the lower end of the hemispherical shell 22. The straight cylindrical section 21 is a hollow annular structure and is rotatably connected to the top of the tower body 10. Additionally, an exhaust pipe 23 is installed on the top of the hemispherical shell 22, and the exhaust pipe 23 communicates with the inner cavity of the tower cover 20. During operation, waste gas generated in industrial production enters the tower body 10 through the inlet pipe 11, is sprayed and washed by the spray assembly 30, and finally flows out of the tower through the exhaust pipe 23.

[0025] In this embodiment, the exhaust pipe 23 is made of a rigid material, such as stainless steel. The exhaust pipe 23 penetrates the top wall of the hemispherical shell 22 and is rotatable relative to the hemispherical shell 22. Thus, during use, the exhaust pipe 23 is connected to external equipment and remains stationary, while the tower cover 20 rotates relative to the tower body 10 under the driving action of the first driving member 40, ensuring that the rotation of the tower cover 20 does not affect the normal operation of the exhaust pipe 23. Furthermore, a bearing is provided at the connection between the exhaust pipe 23 and the hemispherical shell 22 to improve rotational smoothness. Simultaneously, a sealing ring is provided at the connection between the two to enhance sealing and prevent exhaust gas leakage.

[0026] Please see Figure 5 In this embodiment, a groove 101 is provided at the outer edge of the upper surface of the tower body 10, and a flange 201 is provided at the outer edge of the lower surface of the straight cylindrical section 21 of the tower cover 20. The flange 201 and the groove 101 cooperate with each other. The cooperation between the flange 201 and the groove 101 ensures that the user can quickly install the tower cover 20 on the top of the tower body 10. As a preferred embodiment, a plurality of steel balls 102 are rotatably embedded in the bottom wall of the groove 101. The steel balls 102 can rotate relative to the tower body 10 but cannot be separated from the tower body 10. The lower surface of the flange 201 abuts against the steel balls 102. Thus, when the tower cover 20 rotates, it can drive the steel balls 102 to rotate, thereby reducing the friction between the tower cover 20 and the tower body 10. Furthermore, a bushing 202 is fixedly sleeved on the outside of the flange 201. The bushing 202 is made of copper alloy material, which has high hardness and high wear resistance to reduce wear between parts. In addition, a sealing ring is provided on the upper surface of the flange 201, which tightly abuts against the lower surface of the tower cover 20, thereby playing a sealing role and preventing exhaust gas leakage.

[0027] A guide rod 24 is installed on the inner wall of the straight section 21 of the tower cover 20, and the spray assembly 30 is slidably installed on the guide rod 24. Specifically, the spray assembly 30 includes a slider 31 and a spray pipe 32. The slider 31 is slidably sleeved on the outside of the guide rod 24, and the spray pipe 32 is fixedly connected to the slider 31. Multiple nozzles 33 are installed on the spray pipe 32 along its extension direction. The second driving member 50 is used to drive the slider 31 to slide along the guide rod 24.

[0028] In the exhaust gas scrubbing treatment tower of this utility model, during operation, the water distribution mechanism injects scrubbing liquid (e.g., water) into the spray pipe 32, and then sprays it out through each nozzle 33. At the same time, under the action of the first drive assembly 40, the tower cover 20, together with the internal spray pipe 32 and nozzle 33, rotates synchronously relative to the tower body 10. Meanwhile, under the action of the second drive assembly 50, the slider 31, together with the spray pipe 32 and nozzle 33 on it, slides relative to the guide rod 24. During the rotation and sliding of the nozzle 33, the spray coverage area can be increased, the uniformity of the spray water in the tower body 10 can be improved, the spray water distribution can be more extensive, and the rising flue gas can fully countercurrent contact with the spray water, thereby improving the scrubbing effect.

[0029] In a preferred embodiment, the nozzle 33 is a fan-shaped nozzle. This nozzle can achieve spraying over a large area, with a spray angle between 90° and 180°, effectively covering a large area.

[0030] Please refer to it again. Figure 2 , Figure 4 In this embodiment, the first driving component 40 includes a gear motor 41. The body of the gear motor 41 is fixedly mounted on the outer wall of the tower body 10. A gear 42 is fixedly mounted on the output shaft of the gear motor 41. A gear ring 43 is fixedly sleeved on the outside of the straight cylindrical section 21 of the tower cover 20, and the gear ring 43 meshes with the gear 42. During operation, the gear motor 41 is driven to rotate the gear 42, which in turn drives the gear ring 43 to rotate, further driving the straight cylindrical section 21 to rotate. At this time, the function of the spray assembly 30 rotating relative to the tower body 10 is realized. Furthermore, the gear motor 41 is a forward and reverse reversible motor. During operation, the gear motor 41 drives the gear ring 43 to rotate 90° forward and then rotate in the reverse direction to return to the center position, and then rotates 90° in the reverse direction and then rotates in the forward direction to return to the center position. This repeated operation avoids the problem of excessive winding of the water distribution main pipe 34 due to excessive rotation of the tower cover 20.

[0031] In addition, the outer diameter of gear 42 is much smaller than the outer diameter of gear ring 43, so as to achieve the deceleration motion of gear ring 43 and ensure the stability of tower cover 20 rotation.

[0032] In this embodiment, there are two guide rods 24 arranged in parallel, and two sliders 31, with one slider 31 slidably mounted on one guide rod 24. A connecting rod 311 is fixedly connected between the two sliders 31. The connecting rod 311 is a T-shaped rod, and the second driving member 50 is used to drive the connecting rod 311 to move.

[0033] The spray pipe 32 is a serpentine pipe closed at both ends. The serpentine shape ensures that the spray pipe 32 has a sufficient length within the limited space. The serpentine pipe is fixedly connected to both sliders 31. A water distribution main pipe 34 is connected to the spray pipe 32 and communicates with it. The water distribution main pipe 34 is used to connect to the washing liquid supply source. The water distribution main pipe 34 is a flexible hose that extends through the straight section 21 to the outside of the tower cover 20. In addition, the water distribution main pipe 34 has sufficient length inside the tower to meet the rotation requirements of the tower body 20.

[0034] In this embodiment, the connecting rod 311 slidably passes through the outside of the straight section 21. The second driving member 50 is a linear drive actuator, the extended end of which is fixedly connected to the connecting rod 311, thereby driving the spray assembly 30 to slide along the guide rod 24 by moving the connecting rod 311. In one specific embodiment, the second driving member 50 is a cylinder. In other embodiments, the second driving member 50 can also be a linear drive actuator such as an electric push rod, which is not limited here.

[0035] The exhaust gas scrubbing treatment tower of this utility model also includes a settling tank 60. The settling tank 60 has an opening at its upper end and is fixedly installed at the bottom of the tower body 10. During operation, the sprayed water eventually settles into the settling tank 60. A liquid outlet pipe 601 is connected to the side wall of the settling tank 60 for discharging the scrubbing water from the settling tank 60. At the same time, an ash discharge window 602 is detachably installed on the side wall of the settling tank 60 for cleaning impurities in the settling tank 60 after opening the ash discharge window 602. In specific implementation, a water pump can be installed on the liquid outlet pipe 601, and a filter can be installed at the liquid inlet end of the liquid outlet pipe 601 to ensure that impurities in the liquid are filtered out before discharge.

[0036] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the scope of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
