Description

Technical Field

[0001] This utility model relates to the field of spray tower packing replacement, specifically an energy-saving and environmentally friendly waste gas purification and treatment device. Background Technology

[0002] When dusty or oily waste gas passes through the spray tower, a liquid medium is sprayed out at a suitable location inside the tower (depending on the design). Some of these media are alkaline solutions, while others are sulfuric acid solutions. If the waste gas is acidic, an alkaline solution is chosen to neutralize the acidity. If the waste gas is alkaline, a sulfuric acid solution is chosen for absorption. The specific acid or alkaline solution chosen depends on the nature of the waste gas.

[0003] The spray tower also contains packing material. When the packing material needs to be replaced after a long period of use, tools are required to remove the packing balls one by one. After all the packing balls are removed, the replacement can be carried out, which is inefficient. Utility Model Content

[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 Figures 1-6 In this embodiment of the utility model, an energy-saving and environmentally friendly waste gas purification device includes a spray tower 1 with a square cross-section. An inlet pipe 2 is installed at the input end of the spray tower 1, and an exhaust pipe 3 is connected to the output end of the spray tower 1. Two support plates 13 are fixedly installed on the inner wall of the spray tower 1, and two sets of rotating door structures are rotatably installed on the outer wall of the spray tower 1. The bottom end of the rotating door structure is flush with the top end of the support plate 13. The rotating door structure includes two symmetrically opening or closing rotating doors 6. The front part of the support plate 13 is a solid structure, and the rear part of the front part of the support plate 13 is a porous structure. A synchronization mechanism is installed on the segmental solid structure. The synchronization mechanism is used to drive the two rotating doors 6 in a group to open or close synchronously. Guide rail structures are installed on both sides of the inner wall of the spray tower 1. The guide rail structure includes four guide rails 8 distributed in a four-corner pattern. A power mechanism is installed on one side of the inner wall of the spray tower 1. The power mechanism is located between the upper and lower guide rails 8 and extends to the outside of the spray tower 1. Fixed seats 4 are fixedly installed on the outer sides of both ends of the spray tower 1. Rotating seats 5 are rotatably installed on the inner side of the fixed seats 4. The rotating seats 5 are fixedly connected to the front end of the rotating door 6. A packing layer 11 is slidably installed on the inner side of the four guide rails 8 in the same group.

[0022] In this embodiment: when the device is used to purify the exhaust gas, the exhaust gas is pumped by the air pump and enters the spray tower 1 through the air inlet pipe 2. Then, the exhaust gas is purified by the interception of the packing balls inside the packing layer 11 and the spraying action. The purified gas is discharged through the exhaust pipe 3 or further processed.

[0023] After the packing layer 11 has been used for a long time, it needs to be replaced. At this time, the power mechanism is started, and the power mechanism drives the rotating door 6 connected to it to open outward. The rotating door 6 drives another rotating door 6 to open synchronously through the synchronization mechanism. At this time, the sealing of the packing layer 11 can be removed, and the packing layer 11 can be pulled outward to replace it.

[0024] It should be noted that the packing layer 11 is an integral design, with packing balls filling the interior of the packing layer 11, which facilitates overall replacement. The outer layer of the packing layer 11 has a porous structure.

[0025] Please refer to this carefully. Figure 3 and Figure 5 The power mechanism includes a pipe 7 that extends from one end outside the spray tower 1 into the inner cavity of the spray tower 1. A sleeve 9 is fixedly installed at the input end of the pipe 7. An inlet 23 is provided at the connection position between the sleeve 9 and the pipe 7. A telescopic rod 10 is slidably installed on the inner wall of the sleeve 9. A spring 22 is fixedly installed between the protrusion of the telescopic rod 10 on the inner wall of the sleeve 9 and one end of the inner wall of the sleeve 9. A pulley 12 is rotatably installed at the end of the telescopic rod 10 located outside the sleeve 9. A guide rail 24 that is slidably connected to the pulley 12 is installed on the back end of a rotating door 6.

[0026] In this embodiment: when the revolving door 6 is opened, the hydraulic pump sends hydraulic oil into the inner cavity of the sleeve 9 through the pipe 7 and the inlet 23. The hydraulic oil pushes the protrusion (i.e., the piston part) at one end of the telescopic rod 10. At this time, the telescopic rod 10 is pushed outward, and the spring 22 is compressed. Since the telescopic rod 10 can only move along the installation direction of the guide rail 8, the telescopic rod 10 pushes the revolving door 6 to open outward through the pulley 12. At this time, the revolving door 6 drives the rotating seat 5 and the fixed seat 4 to rotate relative to each other. At this time, the pulley 12 slides in the guide rail 24.

[0027] When the hydraulic pump draws out the hydraulic oil, the spring 22 returns to its original position, thus resetting the telescopic rod 10.

[0028] Please refer to this carefully. Figure 4 and Figure 5The synchronization mechanism includes a mounting box 14 fixedly installed at the bottom of the support plate 13. A first pulley 17 is rotatably installed inside the mounting box 14. The first pulley 17 is connected to a second pulley 19 via a transmission belt 18. A toothed block 20 is integrally formed on the outer circumference of the bottom end of the second pulley 19. A gear 21 meshes with the outer circumference of the toothed block 20. The gear 21 is symmetrically arranged with the first pulley 17. A synchronization shaft that is rotatably connected to the support plate 13 is fixedly installed at the top center of both the gear 21 and the top center of the first pulley 17. A swing arm 16 is fixedly connected to the top of the two synchronization shafts. A pulley is rotatably installed at the end of the swing arm 16 away from the synchronization shaft. A groove 15 for the pulley to slide is opened at the back end of the rotating door 6. The vertical section of the groove 15 is convex and the groove 15 is hooked to the pulley.

[0029] In this embodiment: when the aforementioned rotating door 6 is opened, the opened rotating door 6 pulls the pulley through the slide groove 15. During the process of the pulley being pulled, the swing arm 16 rotates. The rotating swing arm 16 drives the first pulley 17 to rotate through the synchronous shaft. The first pulley 17 drives the second pulley 19 to rotate in the same direction and synchronously through the transmission belt 18. The rotating second pulley 19 drives the gear 21 to rotate synchronously in the opposite direction through the tooth block 20. At this time, the other rotating door 6 opens synchronously. Conversely, when the power mechanism is shortened, the two rotating doors 6 close synchronously.

[0030] This design allows the two rotating doors 6 to open simultaneously, thereby replacing the packing layer 11 and reducing downtime.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
