Description

Technical Field

[0001] This utility model relates to the field of desulfurization tower technology, specifically a desulfurization tower spray layer cleaning device. Background Technology

[0002] Desulfurization towers are core equipment used to treat sulfur dioxide in industrial waste gas. They are widely used in coal-fired power plants, steel, chemical, and metallurgical industries to reduce environmental problems such as acid rain. The spray layer in the desulfurization tower uses multiple spray pipes for spraying. In the existing technology, the spray pipes are purged by a blowing device to remove the impurities that clog the pipes. However, some scale adheres to the inner wall of the pipes, making it difficult to blow the scale off completely, resulting in an unsatisfactory cleaning effect on the pipes.

[0003] For example, patent publication number CN222342487U specifically describes a spray layer device for a desulfurization tower, relating to the field of spray technology. It includes a main spray pipe and spray branch pipes, with the branch pipes vertically connected to the main spray pipe. Each branch pipe includes a first spray pipe and a second spray pipe. The first spray pipe is equipped with a valve, and the second spray pipe has flanges at both ends, with blind flanges on the outer sides of the flanges. Several nozzles are evenly distributed on the second spray pipe. By setting up several sets of spray branch pipes and installing valves on the first spray pipes, the second spray pipe can be sprayed without stopping the desulfurization tower. The spray pipe enables online cleaning and maintenance, greatly reducing the risk of blockage. Furthermore, by placing both ends of the second spray pipe outside the desulfurization tower, it eliminates the need for extraction and purging. It can be directly connected to a pipeline purging device to remove impurities from the second spray pipe and avoids the need for secondary cleaning inside the desulfurization tower. While the operation is simple, there is a problem: although the purging device removes blockages from the pipe, some scale adheres to the inner wall, making it difficult to remove completely, resulting in a less than ideal cleaning effect. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a desulfurization tower spray layer cleaning device, which solves the problem that while the spray pipe is purged using a purging device to remove impurities that clog the inside, some scale adheres to the inner wall of the pipe, making it difficult to fully blow off the scale and resulting in an unsatisfactory cleaning effect.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a desulfurization tower spray layer cleaning device, including a spray pipe, with switch valves installed at both ends of the spray pipe, an inlet pipe at the bottom of one end of the spray pipe, a sealing mechanism on the inlet pipe, and an inner wall cleaning mechanism on one side of the spray pipe.

[0006] The inner wall cleaning mechanism includes an elastic strip and a support frame. Brush bristles are fixedly connected to the elastic strip, and an insertion hole is opened at one end of the elastic strip. A mounting base is fixedly connected to the support frame, and a drive motor is fixedly installed on the top of the mounting base. A driving bevel gear is fixedly connected to the end of the output shaft of the drive motor. A driven bevel gear is provided on one side of the driving bevel gear. A connecting shaft is fixedly connected to the end of the driven bevel gear. A connecting rod is fixedly connected to the end of the connecting shaft. A threaded post is fixedly connected to the end of the connecting rod. An anti-detachment cap is provided on one side of the threaded post, and a threaded groove is opened inside the anti-detachment cap.

[0007] Preferably, the spray pipe passes through the desulfurization tower at both ends and extends partially to the outside of the desulfurization tower. A fixing plate is fixedly connected to the spray pipe, and the support frame is fixedly installed on the fixing plate so that the support frame can remain stable.

[0008] Preferably, the insertion hole matches the threaded post, and the diameter of the insertion hole is smaller than the outer diameter of the anti-detachment cap, so that the anti-detachment cap can limit the elastic strip and prevent the elastic strip from separating from the threaded post.

[0009] Preferably, the driving bevel gear meshes with the driven bevel gear, and the output shaft end of the drive motor is connected to the connecting shaft through the driving bevel gear and the driven bevel gear, so that the drive motor can drive the connecting shaft to rotate.

[0010] Preferably, the connecting rod is perpendicular to the connecting shaft and the threaded column, and the central axis of the connecting shaft is parallel to the central axis of the threaded column, so that the threaded column and the connecting shaft are misaligned and parallel, thereby enabling the rotation of the connecting shaft to drive the threaded column to make a circular motion.

[0011] Preferably, the threaded groove matches the threaded post, and the anti-loosening cap is threadedly connected to the threaded post through the threaded groove, so that the anti-loosening cap can be screwed onto the threaded post and is easy to remove.

[0012] Preferably, the sealing mechanism includes a mounting ring disposed inside the inlet pipe, the inlet pipe having a sealing screw hole, a connecting strip fixedly connected to the end of the mounting ring, a sealing cap fixedly connected to the end of the connecting strip, and a sealing screw fixedly connected to the end of the sealing cap, which can seal the inlet pipe and prevent water leakage during normal spraying operation.

[0013] This invention provides a cleaning device for the spray layer of a desulfurization tower. Compared with the prior art, it has the following advantages:

[0014] 1. The desulfurization tower spray layer cleaning device opens the valves at both ends, and then sends an elastic strip with bristles into the spray pipe through the inlet pipe. The insertion hole on the elastic strip is fitted onto the threaded column, and the drive motor pulls the elastic strip to move back and forth continuously inside the spray pipe, so that the bristles continuously sweep away the scale on the inner wall, thoroughly cleaning the scale. Then, in conjunction with the blowing device, the debris is discharged, effectively improving the cleaning effect.

[0015] 2. The desulfurization tower spray layer cleaning device can seal the inlet pipe by screwing the sealing screw into the sealing screw hole and fixing the sealing cap to the end of the inlet pipe, thus preventing water leakage during normal spraying operation. Attached Figure Description

[0022] 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.

[0023] Please see Figures 1-4This utility model provides a technical solution: a desulfurization tower spray layer cleaning device, including a spray pipe 1, with switch valves 3 installed at both ends of the spray pipe 1, which can be connected to a purging device to blow out the debris inside the spray pipe 1 from the other end. An inlet pipe 5 is provided at the bottom of one end of the spray pipe 1, and a sealing mechanism 4 is provided on the inlet pipe 5. An inner wall cleaning mechanism 2 is provided on one side of the spray pipe 1, which can clean the scale on the inner wall of the spray pipe 1. Combined with the purging device, it can effectively clean out the debris and effectively improve the cleaning effect.

[0024] The inner wall cleaning mechanism 2 includes an elastic strip 201 and a support frame 204. The elastic strip 201 can be made of spring steel, which has good deformation and recovery capabilities. The spray pipe 1 passes through the desulfurization tower at both ends and extends partially to the outside of the desulfurization tower. A fixed plate is fixedly connected to the spray pipe 1, and the support frame 204 is fixedly installed on the fixed plate to ensure the stability of the support frame 204. Brush bristles 202 are fixedly connected to the elastic strip 201. The brush bristles 202 have a certain degree of elasticity, allowing them to pass through the inlet pipe 5 and reach the interior of the spray pipe 1, where they are naturally open and make contact with the inner wall. The elastic strip 201 has a hole 203 at one end for easy cleaning of scale on the inner wall. A mounting base 205 is fixedly connected to the support frame 204. A drive motor 206 is fixedly mounted on the top of the mounting base 205. A drive bevel gear 207 is fixedly connected to the output shaft end of the drive motor 206. A driven bevel gear 208 is provided on one side of the drive bevel gear 207. A connecting shaft 209 is fixedly connected to the end of the driven bevel gear 208. The drive bevel gear 207 meshes with the driven bevel gear 208. The output shaft end of the drive motor 206 passes through the drive bevel gear 207. The driven bevel gear 208 is connected to the connecting shaft 209, enabling the drive motor 206 to rotate the connecting shaft 209. A connecting rod 210 is fixedly connected to the end of the connecting shaft 209, and a threaded post 211 is fixedly connected to the end of the connecting rod 210. The connecting rod 210 is perpendicular to the connecting shaft 209 and the threaded post 211. The central axis of the connecting shaft 209 is parallel to the central axis of the threaded post 211, making the threaded post 211 and the connecting shaft 209 offset and parallel. This allows the rotation of the connecting shaft 209 to drive the threaded post 211 to perform circular motion. 203 is matched with the threaded post 211. The diameter of the insertion hole 203 is smaller than the outer diameter of the anti-detachment cap 212, so that the anti-detachment cap 212 can limit the elastic strip 201, thereby preventing the elastic strip 201 from separating from the threaded post 211. The threaded post 211 is provided with an anti-detachment cap 212 on one side. The anti-detachment cap 212 has a threaded groove 213 inside. The threaded groove 213 matches the threaded post 211. The anti-detachment cap 212 is threadedly connected to the threaded post 211 through the threaded groove 213, so that the anti-detachment cap 212 can be screwed on the threaded post 211 and is easy to remove.

[0025] Please see Figure 1 and Figure 5 The sealing mechanism 4 includes a mounting ring 403, which is disposed inside the inlet pipe 5. A sealing screw hole 402 is provided inside the inlet pipe 5. A connecting band 401 is fixedly connected to the end of the mounting ring 403 to prevent the sealing cap 404 from being lost. A sealing cap 404 is fixedly connected to the end of the connecting band 401. A sealing screw 405 is fixedly connected to the end of the sealing cap 404. The sealing cap 404 can be fixed to the end of the inlet pipe 5 by screwing the sealing screw 405 into the sealing screw hole 402, thereby sealing the inlet pipe 5 and preventing water leakage during normal spraying operations.

[0026] During operation, the switch valves 3 at both ends are opened, and the elastic strip 201 with bristles 202 is then fed into the spray pipe 1 through the inlet pipe 5. The insertion hole 203 on the elastic strip 201 is then fitted onto the threaded post 211, and the anti-detachment cap 212 is screwed onto the threaded post 211. Then, the drive motor 206 drives the active bevel gear 207 to rotate, which in turn drives the driven bevel gear 208 to rotate. The driven bevel gear 208 then drives the connecting shaft 209 to rotate, which in turn drives the connecting rod 210 to rotate. The connecting rod 210 then drives the threaded post 211 to rotate, causing the threaded post 211 to make a circular motion. This causes the elastic strip 201 to move back and forth continuously inside the spray pipe 1, allowing the bristles 202 to continuously sweep away the scale on the inner wall, thoroughly cleaning the scale. Then, in conjunction with the blowing device, the debris is discharged, effectively improving the cleaning effect.

[0027] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
