[0029] 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.
[0030] In the embodiments, by Figure 1-4 The present invention provides a spray device for treating waste gas. The present invention includes a treatment tank 1 and a gas-liquid separator 23. A hollow rotating cylinder 2 is rotatably connected inside the treatment tank 1. A flow-receiving plate 3 is fixedly connected to the outside of the hollow rotating cylinder 2. A flow-receiving cylinder 4 is fixedly connected inside the flow-receiving plate 3. A first flow-receiving plate 5 is fixedly connected to the inner wall of the flow-receiving cylinder 4. A second flow-receiving plate 6 is fixedly connected to the inner wall of the flow-receiving cylinder 4. A storage box 18 is fixedly connected to the bottom of the treatment tank 1.
[0031] In this embodiment, in actual use, the bypass plate 3 is used to guide the flow of exhaust gas and increase the contact time between the exhaust gas and the spray liquid. The guide tube 4, the first guide plate 5 and the second guide plate 6 work together to further optimize the flow path of the exhaust gas and improve the purification efficiency.
[0032] Specifically, refer to Figure 5 A worm gear 12 is fixedly connected to the outside of the hollow rotating drum 2. A servo motor 13 is fixedly installed on the top of the processing tank 1. A worm 14 that meshes with the worm gear 12 is fixedly connected to the output shaft of the servo motor 13. A rotating bracket 7 is fixedly connected to the outside of the hollow rotating drum 2. A rotating rod 8 is rotatably connected inside the rotating bracket 7. A cleaning brush 9 is fixedly connected to the outside of the rotating rod 8. A gear 10 is fixedly connected to the top of the rotating rod 8. A gear disc 11 that meshes with the gear 10 is fixedly connected to the inner top wall of the processing tank 1.
[0033] In this embodiment, in actual use, the servo motor 13 meshes with the worm gear 12 through the worm 14 to drive the hollow drum 2 to rotate. The hollow drum 2 is fixedly connected to the outside of the nozzle 2. There are six guide tubes 4 on the flow plate 3. The uniform distribution of the spray liquid and the full contact of the exhaust gas are achieved by the hollow drum 2 driving the nozzle 20 to rotate.
[0034] It should be noted that, since the hollow rotating drum 2 drives the rotating support 7 to rotate, and the gear 10 meshes with the gear plate 11, the gear 10 will drive the rotating rod 8 to rotate, thereby causing the cleaning brush 9 to clean the inner wall of the treatment tank 1, preventing spray liquid residue and impurity accumulation.
[0035] Specifically, refer to Figure 2 A rotary joint 15 is provided on the top of the hollow rotating cylinder 2. A water delivery pipe 16 is fixedly connected to the end of the rotary joint 15 away from the hollow rotating cylinder 2. A filter plate 19 is slidably connected inside the storage box 18. A water pump 17 is fixedly installed on the top of the storage box 18. The end of the water delivery pipe 16 away from the rotary joint 15 is connected to the water outlet of the water pump 17. The water inlet of the water pump 17 extends into the interior of the storage box 18.
[0036] In this embodiment, in actual use, the rotary joint connects the water delivery pipe 16 and the hollow rotating drum 2 to ensure that the spray liquid can be smoothly delivered during rotation. Impurities are filtered through the filter plate 19 to achieve the recycling of the spray liquid. The filter plate 19 is fixedly connected with a handle, which can be used to easily pull out the filter plate 19 for replacement. The water pump 17 draws the spray liquid from the storage tank 18 and delivers it to the hollow rotating drum 2 through the water delivery pipe 16 to achieve the recycling of the spray liquid.
[0037] In this embodiment, in actual use, an air inlet pipe 21 is fixedly connected to the front of the treatment tank 1, an air outlet pipe is fixedly connected to the top wall of the treatment tank 1, a filter 22 is fixedly connected to the outside of the air outlet pipe, the air outlet end of the filter 22 is fixedly connected to the gas-liquid separator 23, the filter 22 is mainly composed of activated carbon filter screen, the waste gas after treatment is further purified by the filter 22 to ensure that the emission meets the standards, the liquid outlet of the gas-liquid separator 23 is fixedly connected to the recovery pipe 24, the end of the recovery pipe 24 away from the gas-liquid separator 23 is fixedly connected to the storage tank 18, the gas-liquid separator 23 recovers the separated spray liquid to the storage tank 18 through the recovery pipe 24, realizing the recycling of the spray liquid.
[0038] Working principle:
[0039] Exhaust gas enters the interior of treatment tank 1 through inlet pipe 21. The exhaust gas is guided by flow plate 3, flow guide cylinder 4, first flow guide plate 5 and second flow guide plate 6 to increase the contact time between exhaust gas and spray liquid. Spray liquid is drawn from storage tank 18 by water pump 17 and transported to hollow rotating drum 2 through delivery water pipe 16. At the same time, servo motor 13 drives hollow rotating drum 2 to rotate through worm gear 14 and worm wheel 12. The hollow rotating drum 2 drives the nozzle 20 to rotate to achieve uniform distribution of spray liquid and full contact of exhaust gas. The hollow rotating drum 2 also drives rotating bracket 7 to rotate. Since gear 10 meshes with gear disk 11, gear 10 drives rotating rod 8 to rotate, so that cleaning brush 9 cleans the inner wall of treatment tank 1. The treated exhaust gas is further purified by filter 22, and the separated spray liquid is recovered to storage tank 18 through recovery pipe 24 through gas-liquid separator 23, realizing the recycling of spray liquid.
