Description

Technical Field

[0001] This utility model relates to the field of exhaust gas absorption tower technology, specifically an exhaust gas absorption tower that is easy to maintain. Background Technology

[0002] In existing technologies, exhaust gas absorption towers are widely used in chemical, pharmaceutical and other fields to treat harmful gases such as volatile organic compounds (VOCs), acidic gases (such as HCl, SO2) and ammonia (NH3).

[0003] However, the packing layer of traditional exhaust gas absorption towers is prone to blockage during operation due to particulate matter accumulation, chemical reaction product deposition, or uneven liquid distribution.

[0004] This blockage can lead to a significant decrease in gas-liquid contact efficiency, increased equipment operating resistance, and even affect the overall treatment effect of exhaust gas.

The two sets of protective shells 13 are fixedly installed on the upper and lower sides of the outer surface of one side of the processing tower 1. The eccentric wheel 11 is located at the lower end of the honeycomb hole material support plate 18. The honeycomb hole material support plate 18 is fixedly installed on the lower outer surface of the grid material distribution rack 19. The top packing protective limit net 20 is fixedly installed on the upper outer surface of the grid material distribution rack 19. The lower outer surface of the guide rod 8 is fixedly connected to one side of the upper outer surface of the middle frame of the top packing protective limit net 20.

[0031] The motor 14 is fixed to one side of the upper outer surface of the protective shell 13. The worm gear 17 and worm 16 are both located inside the protective shell 13. The rotating shaft 15 is connected to the lower outer surface of the motor 14. Two sets of worms 16 are fixedly installed on the outer walls of the upper and lower ends of the rotating shaft 15. The worm gear 17 is located on one side of the outer surface of the worm 16, and the worm 16 and worm gear 17 mesh with each other. The worm gear 17 is fixedly installed on the outer wall of one end of the driven shaft 10. A bearing is provided between the rotating shaft 15 and the protective shell 13, and the rotating shaft 15 is rotatably connected to the protective shell 13 through the bearing. Bearings are also provided between the driven shaft 10 and the protective shell 13, and the processing tower 1, and the driven shaft 10 is rotatably connected to the protective shell 13 and the processing tower 1 through the bearing.

The transmission ratio of the worm gear 16 and the worm wheel 17 is set to 1:20-1:30, and the speed range of the motor 14 is 200-300 r / min.

[0032] It should be noted that this utility model is an easy-to-maintain exhaust gas absorption tower. The treatment tower 1, exhaust gas inlet 2, exhaust outlet 3, treatment liquid spraying structure 4, and demister 6 described in this article are all existing technologies and can be effectively known to those skilled in the art. Specific details will not be elaborated further. The packing support assembly 7 fills the packing material into the grid-like material distribution frame 19 on the outer surface of the upper end of the honeycomb perforated material support plate 18, and is covered by the top packing protective limiting net 20. The operation of the motor 14 in the packing vibration structure 5 drives the rotating shaft 15 to rotate. The rotating shaft 15 drives two sets of worm gears 16 to rotate. The worm gears 16 drive the driven shaft 10 to rotate through the worm wheel 17. The driven shaft 10 drives the eccentric wheel 11 to rotate. The eccentric wheel 11 causes the packing support assembly 7 to vibrate up and down, causing the guide rod 8 to move along the guide ring 9. Due to the limiting effect of the grid-like material distribution frame 19 and the top packing protective limiting net 20, the packing material is easily limited, ensuring that the packing material vibrates properly. During the process, the packing will not shift or accumulate, maintaining a uniform distribution, thereby improving gas-liquid contact efficiency. The packing support component 7 vibrates up and down, keeping the packing layer in a dynamically loose state, avoiding blockage caused by particulate matter or chemical substances. The vibration function, combined with the flushing effect of the treatment liquid spray structure, can promptly remove the adhering substances on the packing surface, improving maintenance convenience. Through the high transmission ratio (1:20-1:30) of the worm gear, the high speed of the motor is converted into the low-frequency vibration (10-15r / min) of the eccentric wheel, preventing the packing from scattering or wearing due to high-frequency vibration, while ensuring sufficient vibration force to loosen the deposits. The motor speed is controlled within the range of 200-300r / min, which can provide stable power output and adapt to the physical characteristics of different packings (such as density and impact resistance), balancing the vibration effect and equipment life. The reasonable matching of transmission ratio and speed can reduce the wear of mechanical parts (such as bearings, worm gears) and extend the service life of the packing vibration structure.
