Description

Technical Field

[0001] This utility model relates to the field of flue gas filtration technology, specifically to a deacidification tower for filtering flue gas. Background Technology

[0002] Flue gas filtration refers to the removal of pollutants from flue gas using physical or chemical methods to reduce their harm to the environment and human health. Most flue gas contains significant amounts of sulfur dioxide and hydrogen chloride, acidic gases produced during combustion. If left untreated, these gases can severely impact the environment and human health. Therefore, flue gas filtration requires the use of deacidification towers. Current technologies often employ wet deacidification methods, where an alkaline solution is atomized and sprayed from the top of the tower. The atomized liquid contacts the rising flue gas, deacidifying it. To increase the contact area between the flue gas and the deacidification liquid, some deacidification towers also use packing materials such as ceramic granules or quartz balls. The adsorption of the deacidification liquid on the packing surface improves the deacidification quality. However, the deacidification liquid is often sprayed directly onto the packing surface, resulting in uneven contact. Furthermore, the deacidification liquid detaches from the packing mainly due to gravity, and the replacement of the deacidification liquid on the packing surface is not timely. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a deacidification tower for filtering flue gas. While stirring the deacidification tower packing, the packing on the lower side is brushed to make the contact between the deacidification liquid and the packing more uniform. The deacidification liquid on the surface of the packing is replaced in time, increasing the contact area between the flue gas and the deacidification liquid and improving the deacidification quality of the flue gas. This can effectively solve the problems in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a deacidification tower for filtering flue gas, comprising a treatment tower and a packing mechanism;

[0005] Processing tower: It is equipped with a high-pressure liquid delivery pipe at the upper end, and an atomizing nozzle is installed at the outlet of the high-pressure liquid delivery pipe;

[0006] The packing mechanism includes a rotating ring, a pusher plate, a turntable, vents, and a top column. The rotating ring is rotatably connected to the center of the treatment tower. Pusher plates are provided on the inner arc surface of the rotating ring. A turntable is rotatably connected to the lower end of the rotating ring. The turntable is in contact with the lower surface of the rotating ring. The space formed by the turntable and the rotating ring is filled with packing material. Vents are provided on the surface of the turntable. A top column is provided in the center of the upper surface of the turntable. The rotating ring and the turntable rotate in opposite directions. While stirring the packing material in the deacidification tower, the packing material on the lower side is brushed to make the contact between the deacidification liquid and the packing material more uniform. The deacidification liquid on the surface of the packing material is replaced in time to increase the contact area between the flue gas and the deacidification liquid and improve the deacidification quality of the flue gas.

[0007] Furthermore, the packing mechanism also includes a brush, which is disposed on the upper surface of the turntable to facilitate brushing the packing.

[0008] Furthermore, the rotating ring and the processing tower, the rotating ring and the rotating disk, and the rotating disk and the processing tower are all rotatably connected by sealed bearings, providing rotational sealing between the rotating disk, the rotating ring, and the processing tower.

[0009] Furthermore, the outer arc surface of the turntable is provided with a lower external toothed ring, and the outer arc surface of the rotating ring is provided with an upper external toothed ring. The right end of the processing tower is rotatably connected to a rotating column, and both the upper and lower ends of the rotating column are provided with drive gears. The lower drive gear meshes with the lower external toothed ring, and the upper drive gear is installed in conjunction with the upper external toothed ring, thereby driving the turntable and the rotating ring to rotate.

[0010] Furthermore, it also includes a microcontroller, which is located on the left side of the processing tower. The input terminal of the microcontroller is electrically connected to an external power source. A motor is provided at the right end of the processing tower. The output shaft of the motor is fixedly connected to the rotating column.

[0011] Furthermore, the right end of the processing tower is rotatably connected to a transmission gear via a rotating shaft, and the upper drive gear and the upper external gear ring are both meshed with the transmission gear, so that the rotation direction of the turntable and the rotating ring are opposite.

[0012] Furthermore, all the pusher plates are inclined plates, which facilitates the up-and-down movement of the seasonings.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This deacidification tower for filtering flue gas has the following advantages:

[0014] While stirring the packing material in the deacidification tower, brushing is applied to the lower packing material to ensure more uniform contact between the deacidification liquid and the packing material.

Detailed Implementation

[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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 This embodiment provides a technical solution: a deacidification tower for filtering flue gas, including a treatment tower 1 and a packing mechanism 4;

[0022] Treatment tower 1: It is equipped with a high-pressure liquid delivery pipe 2 at its upper end. The outlet of the high-pressure liquid delivery pipe 2 is equipped with an atomizing nozzle 3. The flue gas enters the interior of the treatment tower 1 through the air inlet pipe at the lower end of the treatment tower 1. At the same time, the external high-pressure deacidification liquid is delivered through the high-pressure liquid delivery pipe 2 and atomized and sprayed out from the atomizing nozzle 3. The atomized deacidification liquid absorbs the acidic substances in the flue gas and deacidifies the flue gas.

[0023] Packing mechanism 4: It includes a rotating ring 41, a pusher plate 42, a turntable 43, vents 44, and a top column 46. The rotating ring 41 is rotatably connected to the center of the processing tower 1. The inner arc surface of the rotating ring 41 is provided with pusher plates 42. The lower end of the rotating ring 41 is rotatably connected to the turntable 43, which is in contact with the lower surface of the rotating ring 41. The space formed by the turntable 43 and the rotating ring 41 is filled with packing material. Vents 44 are opened on the surface of the turntable 43. A top column 46 is provided in the center of the upper surface of the turntable 43 to prevent the packing material from moving to the center of the rotating ring 41, ensuring that the pusher plate 42 pushes the packing material normally. The turntable 43 and the rotating ring 41 are connected to the turntable 41. The rotating ring 41 rotates in the opposite direction. During the deacidification process, the rotating ring 41 drives the pusher plate 42 to rotate, stirring the packing and making the contact between the atomized deacidification liquid and the packing more uniform. At the same time, the rotating disk 43, rotating in the opposite direction, brushes the packing on the lower side, so that the deacidification liquid absorbing acidic substances can be removed from the packing surface in time, facilitating the adhesion of the subsequent deacidification liquid to the packing surface. The packing mechanism 4 also includes a brush 45, which is set on the upper surface of the rotating disk 43 to facilitate brushing the packing surface. There are connections between the rotating ring 41 and the treatment tower 1, between the rotating ring 41 and the rotating disk 43, and between the rotating disk 43 and the treatment tower 1. A sealed bearing 12 is rotatably connected to provide a rotational seal between the turntable 43, the rotating ring 41, and the processing tower 1. The outer arc surface of the turntable 43 is provided with a lower external gear ring 5, and the outer arc surface of the rotating ring 41 is provided with an upper external gear ring 6. A rotating column 7 is rotatably connected to the right end of the processing tower 1. Both the upper and lower ends of the rotating column 7 are provided with drive gears 8. The lower drive gear 8 meshes with the lower external gear ring 5, and the upper drive gear 8 is fitted with the upper external gear ring 6. The rotating column 7 drives the two drive gears 8 to rotate, thereby driving the turntable 43 and the rotating ring 41 to rotate through gear meshing. The system also includes a microcontroller 10, located at... On the left side of the processing tower 1, the input terminal of the microcontroller 10 is electrically connected to an external power source to control the start and stop of the entire device. The right end of the processing tower 1 is equipped with a motor 9, the output shaft of the motor 9 is fixedly connected to the rotating column 7, and the input terminal of the motor 9 is electrically connected to the output terminal of the microcontroller 10 to provide power for the rotation of the rotating column 7. The right end of the processing tower 1 is rotatably connected to a transmission gear 11 through a rotating shaft. The upper drive gear 8 and the upper external gear ring 6 are both meshed with the transmission gear 11 to transmit the driving force, so that the rotation direction of the turntable 43 and the rotating ring 41 is opposite. The pusher plates 42 are all inclined plates, which facilitates the up and down movement of the packing.

[0024] The working principle of the desulfurization tower for filtering flue gas provided by this utility model is as follows: During use, flue gas enters the interior of the treatment tower 1 through the inlet pipe at the lower end of the treatment tower 1. At the same time, the external high-pressure desulfurization liquid is conveyed through the high-pressure liquid delivery pipe 2 and atomized and sprayed out from the atomizing nozzle 3. The atomized desulfurization liquid falls onto the surface of the packing. The microcontroller 10 starts the motor 9. The output shaft of the motor 9 drives the rotating column 7 and two drive gears 8 to rotate. The lower drive gear 8 meshes with the lower outer gear ring 5, causing the lower outer gear ring 5 to drive the turntable 43 to rotate. The upper drive gear 8 and the upper outer gear ring 6 both mesh with the transmission gear 11. The upper outer toothed ring 6 drives the rotating ring 41 to rotate. The rotating disk 43 rotates in the opposite direction to the rotating ring 41. The inclined pusher plate 42 pushes the packing to move and stir the packing, making the contact between the atomized deacidification liquid and the packing more uniform. As the flue gas rises inside the treatment tower 1, the flue gas and the deacidification liquid on the surface of the packing absorb the acidic substances in the flue gas and deacidify the flue gas. During the deacidification process, the rotating disk 43 drives the brush 45 to brush the surface of the packing on the lower side, so that the deacidification liquid that has absorbed the acidic substances can be removed from the surface of the packing in time, which facilitates the subsequent adhesion of the deacidification liquid to the surface of the packing.

[0025] It is worth noting that the microcontroller 10 disclosed in the above embodiments can be an AT89C4051 microcontroller, and the motor 9 can be freely configured according to the actual application scenario. It is recommended to use an HC-KFS servo motor. The microcontroller 10 controls the operation of the motor 9 using methods commonly used in the prior art.

[0026] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
