Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, and in particular to an industrial desulfurization and tar removal device. Background Technology

[0002] Waste gas treatment refers to the technical process of collecting, purifying, or recycling gases containing pollutants (such as organic compounds, dust, toxic and harmful substances) generated during industrial production or daily life. The aim is to reduce their harm to the environment and human health. When desulfurizing sulfur-containing gases, a large amount of tar is generated and deposited at the bottom of the treatment tower. In order to reduce the impact of tar deposition on the treatment tower, the tar needs to be discharged. To better discharge the tar, we propose an automatic tar discharge device for industrial desulfurization.

[0003] For example, Chinese utility model patent CN213610569U, published on July 6, 2021, discloses an automatic tar discharge device for desulfurization and denitrification. It includes an exhaust gas tower, a first filling layer on the upper side of the exhaust gas tower, a second filling layer below the first filling layer, a high-pressure blower mounted on the upper side of a blower mounting base, a diversion duct on the left side of the high-pressure blower, and wind caps evenly distributed on the upper side of the end of the diversion duct away from the high-pressure blower. The tar discharge assembly includes a tar discharge pipe, an external electromagnetic tar discharge valve, and an internal electromagnetic tar discharge valve. This device achieves the following: the external and internal electromagnetic tar discharge valves prevent exhaust gas leakage; the first and second filling layers prevent particulate matter and tar from escaping, improving exhaust gas treatment efficiency; and the control panel, along with the external and internal electromagnetic tar discharge valves, allows for timed automatic tar discharge, making tar discharge simple and convenient. However, this patent does not solve the problem that existing tar removal devices are not conducive to adjusting the spray direction of the cleaning fluid and the discharge position of the tar during use, and are not conducive to uniformly spraying and cleaning tar at different positions on the inner wall of the treatment tower, thus affecting the tar cleaning effect and the flexibility of discharge. Summary of the Invention

[0004] To address the aforementioned technical problems, this utility model proposes an automatic tar removal device for industrial desulfurization, which solves the problem that existing desulfurization tar removal devices cannot adjust the spray direction of the cleaning liquid, thus affecting the tar removal effect.

[0005] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0006] An automatic tar removal device for industrial desulfurization includes a treatment tower and several nozzles evenly arranged on the tower wall for spraying cleaning liquid, with the nozzles rotatably connected to the treatment tower. The angle between the inner end of the nozzle and the tower wall is less than 90 degrees. A slip ring is slidably fitted on the outside of the treatment tower, and a linkage mechanism is hinged between the slip ring and the nozzle. A sliding drive mechanism on the treatment tower drives the rotation of the nozzles. This invention, by setting the nozzles, delivers the cleaning liquid into the interior of the nozzles and sprays it out from the inner end. Because the inner end of the nozzle is inclined, the sprayed cleaning liquid can clean the tar on the inner wall of the treatment tower. The sliding drive mechanism drives the slip ring to slide on the surface of the treatment tower, and the swinging of the linkage mechanism drives the nozzle to rotate within a certain range, spraying cleaning liquid at different locations on the inner wall of the treatment tower to clean the tar, thus improving the tar cleaning effect.

[0007] Furthermore, the linkage mechanism includes long linkage arms and short linkage arms. The outer wall of the slip ring is provided with multiple sets of long linkage arms at equal intervals and corresponding to the nozzle. The end of each long linkage arm near the slip ring is provided with a first connecting shaft, and the long linkage arm is hinged to the slip ring through the first connecting shaft. The end of each long linkage arm away from the slip ring is provided with a short linkage arm. The end of each short linkage arm near the long linkage arm is provided with a second connecting shaft, and the short linkage arm is hinged to the long linkage arm through the second connecting shaft. The end of each short linkage arm away from the long linkage arm is fixedly connected to the nozzle.

[0008] Furthermore, the sliding drive mechanism includes an electric push rod mounted on the outer wall of the processing tower, and a push arm extending along the axial direction of the processing tower is mounted on the output end of the electric push rod. The end of the push arm away from the electric push rod is connected to a slip ring.

[0009] Furthermore, in order to improve the cleaning effect of spraying, a nozzle is connected to the inner end of the spray pipe.

[0010] Furthermore, the bottom end of the processing tower is provided with a discharge pipe, and the discharge pipe is rotatably connected to a connecting pipe; the lower end of the connecting pipe is cross-connected to a discharge pipe; the discharge pipe or the processing tower is provided with a rotating discharge drive mechanism for driving the discharge pipe to rotate.

[0011] Furthermore, the rotating discharge drive mechanism includes a servo motor mounted on the outer wall of the discharge pipe, a drive shaft mounted on the output end of the servo motor, a gear ring fitted on the outer side of the connecting pipe, and a gear connected to the drive shaft, with the gear meshing with the gear ring.

[0012] Furthermore, in order to control the tar discharge process, a solenoid valve is installed at the top of the discharge pipe.

[0013] Furthermore, in order to better transport and discharge the tar, the discharge pipe is equipped with spiral blades inside, and the spiral blades are rotatably connected to the discharge pipe.

[0014] Furthermore, a drive motor is provided on the side wall of the discharge pipe, and the output end of the drive motor is connected to the spiral blade.

[0015] Furthermore, an air inlet pipe is provided on the side wall of the processing tower, and support legs are provided at the bottom of the processing tower.

[0016] The beneficial effects of this utility model are:

[0017] 1. This utility model uses a spray pipe to deliver cleaning fluid into the inside of the spray pipe and spray it out from the inner end of the spray pipe. Because the inner end of the spray pipe is inclined downwards, the sprayed cleaning fluid can clean the tar on the inner wall of the treatment tower.

[0018] 2. This utility model uses a push arm to drive a slip ring to slide on the surface of the treatment tower. The slip ring drives a long linkage arm to rotate via a first connecting shaft, and the long linkage arm drives a short linkage arm to rotate via a second connecting shaft. With the rotation of the nozzle and the treatment tower, the short linkage arm drives the nozzle to rotate within a certain range, thereby adjusting the spraying direction of the nozzle. This allows for the spraying and cleaning of tar at different locations on the inner wall of the treatment tower, resulting in a cleaner tar removal. This design achieves linkage adjustment of the spraying direction of the cleaning liquid, facilitating the spraying and cleaning of tar at different locations on the inner wall of the treatment tower and improving the tar cleaning effect.

[0019] 3. This utility model uses a servo motor to drive a gear through a drive shaft, which in turn drives a connecting pipe through a gear ring, which in turn drives a discharge pipe to rotate. This allows for adjustment of the discharge position of the discharge pipe, facilitating the discharge of tar from different locations and improving the flexibility of discharge.

[0020] 4. The tar discharge device of this utility model not only realizes the linkage adjustment of the spraying direction of the cleaning liquid and the adjustment of the tar discharge position, which facilitates the uniform spraying and cleaning of tar at different positions on the inner wall of the treatment tower, but also improves the tar cleaning effect and the flexibility of discharge.

[0029] 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.

[0030] like Figure 1 As shown in Embodiment 1 of this utility model, an automatic tar removal device for industrial desulfurization includes a treatment tower 1, with an air inlet pipe 3 installed on the side wall of the treatment tower 1. Several nozzles 20 are evenly arranged on the side wall of the treatment tower 1. The outer ends of the nozzles 20 are connected to a cleaning liquid source via flexible pipes, and these flexible pipes are connected to a liquid pump to supply cleaning liquid to the nozzles 20. This allows the inner end of the nozzles 20 within the treatment tower 1 to spray the cleaning liquid, cleaning the tar from the inner wall of the treatment tower 1. The connection between the nozzles 20 and the treatment tower 1 is a rotatable connection. Furthermore, the angle between the inner end of the nozzle 20 within the treatment tower 1 and the tower wall of the treatment tower 1 is less than 90 degrees; that is, the portion of the nozzle 20 within the treatment tower 1 is bent. Figure 2As shown, the inner end of the nozzle 20 is inclined, causing the cleaning liquid to be sprayed out at an angle at the liquid outlet. In this embodiment, the inner end of the nozzle 20 located inside the treatment tower 1 is inclined downwards, and the angle between the nozzle 20 and the inner wall of the treatment tower 1 below it is 45-80 degrees. A slip ring 15 is slidably fitted on the outer side of the treatment tower 1, and a linkage mechanism is hinged between the slip ring 15 and the nozzle 20. Figure 5 As shown, the treatment tower 1 is equipped with a sliding drive mechanism for pushing the slip ring 15 to slide, which in turn drives the linkage mechanism to swing, thereby causing the nozzle 20 to rotate. Since multiple nozzles 20 are evenly distributed on the treatment tower 1, each nozzle 20 is connected to the slip ring via a linkage mechanism. The sliding of the slip ring can drive the multiple nozzles 20 to rotate within a certain range. The rotation and spraying of the multiple nozzles 20 can cover most of the interior of the treatment tower, thereby improving the cleaning effect. At the same time, the nozzles 20 do not spray directly at a single location, but rotate to spray, making the cleaning fluid spray and clean the treatment tower more evenly.

[0031] Furthermore, such as Figure 6 As shown, the linkage mechanism includes a long linkage arm 17 and a short linkage arm 19 hinged together, forming a two-bar linkage mechanism. Figure 5 As shown, the outer wall of the slip ring 15 is provided with multiple sets of long linkage arms 17 at equal intervals and corresponding to the nozzle 20. Each long linkage arm 17 has a first connecting shaft 16 at its end near the slip ring 15, and the long linkage arm 17 is hinged to the slip ring 15 via the first connecting shaft 16. Each long linkage arm 17 has a short linkage arm 19 at its end away from the slip ring 15. Each short linkage arm 19 has a second connecting shaft 18 at its end near the long linkage arm 17, and the short linkage arm 19 is hinged to the long linkage arm 17 via the second connecting shaft 18. The end of the short linkage arm 19 away from the long linkage arm 17 is fixedly connected to the nozzle 20, so that the sliding of the slip ring 15 drives the swinging of the long linkage arms 17 and the short linkage arms 19, thereby causing the nozzle 20 to rotate within a certain range.

[0032] Example 2 differs from Example 1 in that, as Figure 5 As shown, the sliding drive mechanism includes an electric push rod 13 mounted on the outer wall of the processing tower 1. The output end of the electric push rod 13 is equipped with a push arm 14 extending along the axial direction of the processing tower 1. The end of the push arm 14 away from the electric push rod 13 is connected to a slip ring 15 for pushing the slip ring 15 to slide along the axial direction of the processing tower 1.

[0033] Example 3 differs from Example 1 in that, as Figure 2 As shown, a nozzle is connected to the inner end of the spray pipe 20 to improve the spraying effect.

[0034] Example 4 differs from Example 1 in that, as Figure 2 and Figure 3 As shown, the bottom end of the processing tower 1 is provided with a discharge pipe 7, and the discharge pipe 7 is rotatably connected to a vertical connecting pipe 8. In this embodiment, as... Figure 3 As shown, the lower end of the discharge pipe 7 is rotatably connected to the connecting pipe 8 via a bearing, and the connecting pipe 8 is sleeved on the outside of the lower end of the discharge pipe 7. The lower end of the discharge pipe 7 extends into the connecting pipe 8 to a certain depth, so that tar does not easily contaminate the bearing. The lower end of the connecting pipe 8 is cross-fixedly connected to the discharge pipe 2. In this embodiment, the discharge pipe 2 is arranged laterally and perpendicularly to the connecting pipe 8. In other embodiments, the discharge pipe 2 is arranged at a downward inclination, and the included angle between the discharge pipe 2 and the connecting pipe 8 can be greater than 90 degrees and less than 160 degrees.

[0035] Furthermore, such as Figure 4 As shown, the discharge pipe 7 or the processing tower 1 is equipped with a rotary discharge drive mechanism for driving the discharge pipe 7 to rotate. In this embodiment, the outer wall of the discharge pipe 7 is equipped with a rotary discharge drive mechanism for driving the discharge pipe 7 to rotate.

[0036] In addition, such as Figure 3 As shown, a solenoid valve 6 is installed at the top of the discharge pipe 7.

[0037] Example 5 differs from Example 4 in that, as Figure 4 As shown, the rotating discharge drive mechanism includes a servo motor 10 mounted on the outer wall of the discharge pipe 7. The output shaft of the servo motor 10 faces vertically downwards, and a drive shaft 11 is mounted on the lower end of the output shaft. The drive shaft 11 is connected to a gear 12. A gear ring 9 is fitted on the outer side of the connecting pipe 8. The gear 12 meshes with the gear ring 9, so that the rotation of the gear ring 9 driven by the servo motor 10 drives the rotation of the connecting pipe 8, thereby driving the rotation of the discharge pipe 2 to achieve discharge from multiple directions.

[0038] Example 6 differs from Example 5 in that, as Figure 1 and Figure 2 As shown, the bottom of the processing tower 1 is provided with support legs. A base is also fixedly connected to the bottom of the support legs. In this embodiment, there are two to three support legs, and the discharge pipe 2 extends out from the gap between two of the support legs, allowing it to swing within the gap between the two support legs.

[0039] Example 7 differs from Example 6 in that, as Figure 2 As shown, the discharge pipe 2 is provided with a spiral blade 4 inside, and the end of the spiral blade 4 is rotatably connected to the discharge pipe 2.

[0040] Furthermore, a drive motor 5 is provided on the side wall of the discharge pipe 2, and the output end of the drive motor 5 is connected to the spiral blade 4.

[0041] In addition, a support cylinder coaxial with the connecting pipe 8 is provided on the base to support the discharge pipe 2. At the same time, a short pipe coaxial with the support cylinder can be provided at the bottom of the discharge pipe 2. The short pipe is rotatably connected to the support cylinder through a bearing, so that the support cylinder can both support the discharge pipe 2 and not hinder the rotation of the discharge pipe 2.

[0042] The usage process of this utility model is as follows:

[0043] Sulfur-containing flue gas is discharged into the interior of treatment tower 1 through inlet pipe 3, where treatment tower 1 performs desulfurization treatment on the flue gas. Tar is generated during the treatment process, and over time, the tar adheres to the inner wall of treatment tower 1.

[0044] When tar removal is required, the outer end of the nozzle 20 is connected to an external cleaning fluid via a flexible pipe. A liquid pump pressurizes the cleaning fluid through the flexible pipe into the nozzle 20 and sprays it out. Because the inner end of the nozzle 20 is curved and oriented diagonally downwards, the sprayed cleaning fluid can reach the inner wall of the treatment tower 1 to clean the tar from its surface. The removed tar flows down the inner wall to the bottom of the treatment tower.

[0045] To more thoroughly clean the tar on the inner wall of the treatment tower, an electric push rod 13 drives a push arm 14 to move. The push arm 14 then drives a slip ring 15 to slide on the surface of the treatment tower 1. The slip ring 15 drives a long linkage arm 17 to rotate via a first connecting shaft 16. The long linkage arm 17 then drives a short linkage arm 19 to rotate via a second connecting shaft 18. With the coordinated movement of the spray nozzle 20 and the treatment tower 1, the short linkage arm 19 drives the spray nozzle 20 to rotate, thereby adjusting the spray direction of the spray nozzle 20. This allows for the spraying and cleaning of tar at different locations on the inner wall of the treatment tower 1, resulting in a more thorough cleaning. This system achieves coordinated adjustment of the spray direction of the cleaning fluid, facilitating the spraying and cleaning of tar at different locations on the inner wall of the treatment tower and improving the tar cleaning effect.

[0046] When tar needs to be discharged, the solenoid valve 6 is opened, and the mixture flows through the discharge pipe 7 and connecting pipe 8 into the discharge pipe 2. The drive motor 5 drives the spiral blades 4 to rotate, which in turn moves the mixture and discharges it from the discharge pipe 2. When the tar discharge position needs to be adjusted, the servo motor 10 drives the gear 12 to rotate via the drive shaft 11. The gear 12 then drives the connecting pipe 8 to rotate via the gear ring 9, which in turn drives the discharge pipe 2 to rotate. This adjusts the discharge position of the discharge pipe 2, allowing for convenient tar discharge from different locations and improving discharge flexibility.

[0047] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that any modifications to the technical solutions described in the foregoing embodiments, or equivalent substitutions of some or all of the technical features thereof, within the spirit and principles of the present invention, do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention, and should all be included within the protection scope of the present invention.
