Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment equipment, in particular to waste gas treatment equipment for chemical production. Background Art

[0002] The waste gas generated in the chemical production process often has various characteristics, such as high concentration, high toxicity, strong corrosiveness, flammability and explosiveness, etc., and the waste gas may contain various harmful substances, such as sulfur dioxide, nitrogen oxides, volatile organic compounds, etc. If these waste gases are directly discharged into the atmosphere, it will cause serious pollution to the environment;

[0003] Therefore, when discharging the waste gas from chemical production into the atmospheric environment, it is necessary to make the waste gas contact countercurrently with the spraying liquid through a spray tower, and utilize the spraying and packing effects of the liquid to make the pollutants in the waste gas chemically react or physically adsorb with the liquid, so as to achieve the purpose of purifying the waste gas. As the use time increases, the performance of the packing will gradually decrease, and its adsorption, absorption or reaction ability will weaken, thus affecting the treatment effect of the spray tower on the waste gas. Therefore, it is necessary to regularly replace the packing in the spray tower. However, due to the small diameter of the inspection opening of the spray tower, when replacing the packing, it is necessary to gradually scrape out the packing on the packing rack from the outside with the help of a drill rod, so as to realize the removal of the packing. Therefore, this method of removing the packing is difficult to operate, has low efficiency, and at the same time, it will also cause a certain amount of packing to remain in the packing rack and be difficult to remove. Summary of the Utility Model

[0004] The purpose of the utility model is to provide waste gas treatment equipment for chemical production, which can effectively solve the problems in the background art.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0028] A plurality of spacer meshes 11 are fixedly installed between the material tray 7 and the multiple supporting beams 8. Based on this, by arranging the spacer mesh 11 between the material tray 7 and the supporting beam 8, the packing material can be placed in the material tray 7, and the sprayed water can fall through the packing material in the material tray 7 to the bottom inside the spray tower body 1. Embodiment 2:

[0029] As Figures 2-7 shown, a discharge notch is formed inside the material tray 7, and two guide rails 12 are fixedly installed inside the material tray 7. The longitudinal section of the guide rail 12 is in a T shape. Based on this, by arranging two guide rails 12 inside the material tray 7, a guiding path can be provided for the movement of the connecting shaft 10. A first chute 13 is formed at the top of one of the supporting beams 8, and fixing seats 14 are fixedly installed at the bottom of the supporting beam 8 on both sides of the first chute 13. A guide rod 15 is fixedly installed between the two fixing seats 14. Based on this, by arranging the guide rod 15 inside one of the supporting beams 8, a guiding path can be provided for the movement of the middle position of the pushing plate 9. A slider 17 is fixedly installed at the middle position of the bottom of the pushing plate 9, a cover plate 18 is fixedly installed on one side of the slider 17, mounting grooves 19 are formed on both sides of the pushing plate 9, rotating shafts 20 are fixedly installed at the top and bottom of the connecting shaft 10, two second chutes 21 are formed inside the connecting shaft 10, and the connecting shaft 10 is rotatably installed in the corresponding mounting grooves 19 through the two rotating shafts 20, and the connecting shaft 10 is also slidably installed on the two guide rails 12 through the two second chutes 21.

[0030] It should be noted that the present utility model is an exhaust gas treatment device for chemical production. When removing the packing in the tray 7, the end cover of the inspection port 4 on one side of the corresponding tray 7 can be opened first. Subsequently, the packing at the upper layer position in the tray 7 can be scraped and scattered by using a drill rod. Then, the pull rope 22 can be pulled to one side, so that the two ends of the pull rope 22 drive the corresponding connecting shafts 10 to move in the tray 7 respectively, and the connecting shafts 10 slide reversely on the two guide rails 12 through the two second chutes 21 on the outside. Thus, the two connecting shafts 10 drive the push plate 9 to move towards the inspection port 4 through the rotating shaft 20. Then, the push plate 9 synchronously drives the slider 17 at the bottom to slide on the guide rod 15 and compresses the compression spring 16 outside the guide rod 15 towards one of the fixed seats 14, while the cover plate 18 continuously covers the first chute 13. It can make the push plate 9 move towards the inspection port 4 in the tray 7 and make the two sides of the push plate 9 deform and converge towards the inspection port 4, so as to scrape the packing in the tray 7 towards the inspection port 4. When the packing in the tray 7 is taken out, the pull rope 22 can be released, and the push plate 9 can be reset by means of the rebound force of the compressed compression spring 16.
