Description

Technical Field

[0001] This utility model relates to the field of organic waste gas treatment technology, specifically to a high-efficiency absorption tower. Background Technology

[0002] Organic waste gas is a common type of pollutant in industrial production, mainly originating from industries such as chemical, coating, printing, and pharmaceutical manufacturing. Its composition is complex, containing volatile organic compounds such as benzene, toluene, xylene, alcohols, and esters, and it is characterized by flammability, explosiveness, toxicity, and irritation. If these waste gases are emitted directly without treatment, they will not only exacerbate air pollution, forming photochemical smog and ozone layer depletion, but may also harm human health through inhalation or skin contact, causing headaches, allergies, and even increasing the risk of cancer. Currently, organic waste gas treatment technologies include adsorption, catalytic combustion, and biological treatment, achieving emission standards by recovering or decomposing pollutants.

[0003] Utility model patent CN214552390U discloses a high-efficiency absorption device for organic waste gas, including an absorption tower with a cleaning port on the top surface of the absorption tower, a spray assembly, and a cleaning mechanism. The cleaning mechanism includes a drive motor, the power output end of which passes through the absorption tower and is fixedly connected to a threaded screw. A sliding nut is slidably installed on the outside of the threaded screw, and a lifting plate is fixedly installed on the outer wall surface of the sliding nut. A storage rack is fixedly installed on the top surface of the lifting plate. This utility model, through the installed cleaning mechanism, allows the drive motor to rotate the threaded screw clockwise, which in turn moves the sliding nut upwards, thereby moving the lifting plate upwards. This allows the storage rack to be removed from the cleaning port, and the packing material inside the storage rack can then be taken out. This facilitates the cleaning and replacement of the packing material inside the device, thus ensuring the treatment effect of the device and demonstrating excellent practicality.

[0004] However, common organic waste gas absorption towers require redistribution of the absorbent liquid during its descent. The redistribution structure is usually fixed, and the dripping absorbent liquid falls from fixed through-holes, making it difficult to fully contact the waste gas. Therefore, high-efficiency absorption towers are proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a high-efficiency absorption tower, which has the advantages of uniform dripping of the absorbent during redistribution and full contact with the waste gas, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A high-efficiency absorption tower includes a tower body, an air inlet pipe fixedly installed on one side of the tower body, a cover connected to the top flange of the tower body, a spray pipe fixedly installed on the inner wall of the tower body, and a rotating redistribution assembly provided on the inner wall of the tower body.

[0008] The rotating redistribution assembly includes a redistribution disk rotatably mounted on the inner side wall of the tower body. The redistribution disk is located below the spray pipe. The bottom of the redistribution disk has evenly distributed distribution holes. The top of the redistribution disk has two connecting pipes fixedly installed. The surface of the connecting pipes near the top has ventilation holes. The top of the connecting pipes has a baffle fixedly installed. The tower body is provided with a drive mechanism to rotate the redistribution disk.

[0009] Furthermore, the bottom of the redistribution disc has two connecting holes that are adapted to the connecting pipe, and the top of the cover is fixedly installed with an air outlet pipe.

[0010] Furthermore, a sealing ring is fixedly installed on the inner wall of the tower body, and a sealing groove adapted to the sealing ring is opened on the surface of the redistribution plate.

[0011] Furthermore, the drive mechanism includes a rotating shaft rotatably mounted on the bottom wall of the tower body, the top end of the rotating shaft being fixedly connected to the bottom of the redistribution disk, and a rotating motor that drives the rotating shaft to rotate being fixedly mounted on the bottom of the tower body.

[0012] Furthermore, an inlet pipe is fixedly installed on one side of the tower body, which is connected to a spray pipe. A nozzle is fixedly installed on the inner wall of the spray pipe, with the outlet of the nozzle tilted upward. A drain pipe is fixedly installed at the bottom of the tower body.

[0013] Furthermore, an installation partition is fixedly installed on the inner wall of the tower body. The installation partition is located above the spray pipe, and four installation rings are fixedly installed on the top of the installation partition.

[0014] Furthermore, the mounting ring is internally threaded with a packing cylinder, an ultrasonic vibrator is fixedly mounted on the surface of the packing cylinder, a support leg is fixedly mounted at the bottom of the tower body, and a base plate is fixedly mounted at the bottom end of the support leg.

[0015] Compared with the prior art, this utility model provides a high-efficiency absorption tower with the following beneficial effects:

[0016] This high-efficiency absorption tower features a redistribution disc mounted rotatably on the inner wall of the tower body. The absorbent drips onto the redistribution disc, and a rotating motor drives the rotating shaft, which in turn rotates the redistribution disc. As the absorbent drips from the distribution holes, it rotates and falls, ensuring even contact with the organic waste gas and improving absorption efficiency. This solves the problem of common organic waste gas absorption towers where the absorbent needs to be redistributed during its fall, but the redistribution structure is usually fixed, and the dripping absorbent falls from fixed through-holes, making it difficult to fully contact the waste gas.

[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 to 4 The high-efficiency absorption tower in this embodiment includes a tower body 1, an air inlet pipe 2 fixedly installed on one side of the tower body 1, a cover 3 connected to the top flange of the tower body 1, a spray pipe 4 fixedly installed on the inner wall of the tower body 1, and a rotating redistribution assembly provided on the inner wall of the tower body 1.

[0024] The rotating redistribution assembly includes a redistribution disk 5 rotatably installed on the inner wall of the tower body 1. The redistribution disk 5 is located below the spray pipe 4. Distribution holes 6 are evenly opened at the bottom of the redistribution disk 5. Two connecting pipes 7 are fixedly installed on the top of the redistribution disk 5. Ventilation holes 8 are opened on the surface of the connecting pipes 7 near the top. A cover 9 is fixedly installed on the top of the connecting pipes 7. A drive mechanism for rotating the redistribution disk 5 is provided on the upper part of the tower body 1.

[0025] Specifically, after the absorbent liquid is sprayed above the redistribution disk 5 and comes into contact with the organic waste gas, it falls onto the redistribution disk 5 and drips from the distribution holes 6 at the bottom of the redistribution disk 5. The driving mechanism drives the redistribution disk 5 to rotate, so that the absorbent liquid drips evenly from the redistribution disk 5 and fully contacts the organic waste gas, thereby improving the absorption effect.

[0026] Meanwhile, the bottom of the redistribution plate 5 has two connecting holes 51, which are adapted to the connecting pipe 7, and the top of the cover 3 is fixedly installed with an air outlet pipe 10.

[0027] Among them, a sealing ring 11 is fixedly installed on the inner side wall of the tower body 1, and a sealing groove 52 adapted to the sealing ring 11 is opened on the surface of the redistribution plate 5.

[0028] Secondly, the drive mechanism includes a rotating shaft 12 rotatably mounted on the bottom wall of the tower body 1. The top end of the rotating shaft 12 is fixedly connected to the bottom of the redistribution disk 5. A rotating motor 13, which drives the rotating shaft 12 to rotate, is fixedly mounted on the bottom of the tower body 1. The rotating motor 13 drives the rotating shaft 12 to rotate, which in turn drives the redistribution disk 5 to rotate.

[0029] Please see Figure 1 In this embodiment, an inlet pipe 14 is fixedly installed on one side of the tower body 1, and the inlet pipe 14 is connected to the spray pipe 4. A nozzle 15 is fixedly installed on the inner wall of the spray pipe 4, and the outlet of the nozzle 15 is inclined upward. A drain pipe 16 is fixedly installed at the bottom of the tower body 1. The absorbent liquid enters the spray pipe 4 from the inlet pipe 14 and is sprayed out from the nozzle 15.

[0030] Please see Figure 1 and Figure 3 In this embodiment, an installation partition 17 is fixedly installed on the inner side wall of the tower body 1. The installation partition 17 is located above the spray pipe 4, and four installation rings 18 are fixedly installed on the top of the installation partition 17.

[0031] The installation ring 18 is internally threaded to a packing cylinder 19. An ultrasonic vibrator 20 is fixedly mounted on the surface of the packing cylinder 19. A support leg 21 is fixedly mounted at the bottom of the tower body 1, and a base plate 22 is fixedly mounted at the bottom end of the support leg 21. The ultrasonic vibrator 20 drives the packing cylinder 19 to vibrate, dislodging impurities adhering to the holes on the surface of the packing cylinder 19 and reducing the occurrence of blockage in the packing cylinder 19.

[0032] The working principle of the above embodiment is as follows: organic waste gas is introduced into the tower body 1 through the inlet pipe 2 and comes into contact with the absorbent dripping from the redistribution plate 5. The organic components in the waste gas are absorbed. The organic waste gas enters the area above the redistribution plate 5 through the connecting pipe 7 and enters the tower body 1 above the redistribution plate 5 through the vent hole 8. It comes into contact with the absorbent sprayed from the nozzle 15. The organic waste gas then enters the packing cylinder 19 for adsorption again and is discharged through the outlet pipe 10.

[0033] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that achieves the desired beneficial effect can be implemented. Furthermore, all electrical components in this embodiment are electrically connected to the main controller and power supply. The main controller can be a conventional, known device such as a computer that performs control functions. Those skilled in the art can control the electrical components through simple programming, and the existing disclosed power connection technologies are common knowledge in the field. Therefore, this embodiment will not elaborate further on their specific structural composition and working principles.
