[0002] Waste gas refers to toxic and harmful gases discharged by humans in the process of production and life, especially from chemical plants, steel mills, pharmaceutical plants, coking plants and refineries. The waste gas emitted has a strong odor, seriously polluting the environment and affecting human health.

[0003] A spray device is needed in the process of exhaust gas treatment. When dust-containing flue gas passes through the mist space, the dust particles fall down with the droplets due to the collision, interception and condensation between the dust particles and the droplets. The spray device can filter the dust particles in the exhaust gas. The problem with the prior art is that the existing spray device for exhaust gas treatment does not have the function of water recycling. During use, the used water will be directly discharged, which will cause a waste of water resources, increase the cost of users, and bring inconvenience to users.

[0004] Therefore, in view of the shortcomings of the prior art, it is necessary to provide a water circulation device for waste gas spray treatment to solve the shortcomings of the prior art. Utility Model Content

[0039] The utility model is further described in conjunction with the following embodiments.

[0040] Example 1.

[0041] like Figure 1-3 As shown, a water circulation device for waste gas spray treatment includes a waste gas channel 1, a connecting frame 2 is installed around the outside of the waste gas channel 1, a spray water tank 3 is installed on the top of the connecting frame 2, a circulating water tank 4 is installed at the bottom of the connecting frame 2, circulation mechanisms 5 are arranged on both sides of the connecting frame 2, a spray mechanism 6 is installed on the top of the waste gas channel 1, and a collecting mechanism 7 is arranged below the waste gas channel 1.

[0042] When in use, the connection frame 2 installed outside the exhaust gas channel 1 installs the spray water tank 3 and the circulating water tank 4. The circulating water tank 4 and the spray water tank 3 circulate the sprayed water through the circulation mechanism 5. The spray mechanism 6 and the collecting mechanism 7 installed at the upper and lower ends of the exhaust gas channel 1 can spray the exhaust gas inside the exhaust gas channel 1, and the collecting mechanism 7 collects the exhaust gas into the circulating water tank 4 for the next step of recycling, thereby reducing the exhaust gas treatment cost.

[0043] The circulation mechanism 5 includes a circulation pipeline 8, which is connected between the spray water tank 3 and the circulation water tank 4. A booster pump 9 is installed in the center of the circulation pipeline 8. A bent pipe 10 is installed at one end of the circulation pipeline 8 close to the circulation water tank 4. A circulation water pump 11 is connected to the bent pipe 10, and the circulation water pump 11 is installed at the bottom end of the circulation water tank 4.

[0044] When the water is circulating, the water in the circulating water tank 4 is extracted by the circulating water pump 11 installed in the circulating water tank 4, and the extracted water enters the circulating pipeline 8 through the bent pipe 10. The booster pump 9 installed in the center of the circulating pipeline 8 can prevent the water pressure from being too low, increase the water pressure, improve the pumping effect, and accelerate the circulation rate, and finally send the water into the spray tank 3.

[0045] The spray mechanism 6 includes a temporary water tank 12 , which is installed below the spray water tank 3 . An electric-controlled boost valve 13 is provided inside the temporary water tank 12 , and a boost nozzle group 14 is connected to the bottom of the electric-controlled boost valve 13 .

[0046] The water in the spray tank 3 will flow into the temporary storage tank 12. The electrically controlled Zheng Auntie valve installed inside the temporary storage tank 12 can pump the water in the temporary storage tank 12 into the booster nozzle group 14, so as to facilitate the spraying treatment of the exhaust gas channel 1.

[0047] The collecting mechanism 7 includes a filter plate 15, which is installed at the bottom of the exhaust gas channel 1. A liquid collecting tank 16 is installed at the bottom of the filter plate 15. A guide port 17 is opened in the center of the liquid collecting tank 16. A filter screen 18 is cross-installed inside the guide port 17. The guide port 17 is arranged above the circulating water tank 4.

[0048] After spraying the exhaust gas channel 1, water will fall onto the filter plate 15, and the impurities in the exhaust gas channel 1 will be filtered out by the filter plate 15 to facilitate the recycling of water. The filtered water will enter the collecting tank 16, and the water will flow into the guide port 17 through the sloped collecting tank 16, and will finally fall into the circulating water tank 4 for secondary filtration through the filter net 18 to wait for circulation.

[0049] Fan-shaped nozzles 19 are evenly arranged on the boost nozzle group 14. The boost nozzle groups 14 are staggered and installed. The length of the boost nozzle group 14 is the same as the length of the temporary water tank 12. The fan-shaped nozzles 19 increase the water spraying area. At the same time, the storage and installation of the boost nozzle group 14 can fully cover the interior of the exhaust gas channel 1, thereby increasing the exhaust gas treatment efficiency.

[0050] The filter plate 15 is integrally formed with an anti-splashing protrusion 20, which is installed in parallel with the booster nozzle group 14. The anti-splashing protrusion 20 can prevent water from splashing outward during the spraying process, making it easier for the filter plate 15 to filter the water used to treat the exhaust gas.

[0051] During the production process, the water in the waste gas treatment process is sprayed and collected through the spraying mechanism 6 and the collecting mechanism 7 arranged at the upper and lower ends of the waste gas channel 1. At the same time, the spray water tank 3 and the circulating water tank 4 installed above and below the waste gas channel can ensure the circulation effect of the spraying water through the installation of the circulating mechanism 5, thereby improving the treatment effect of the waste gas spraying, reducing the waste of water resources, reducing the user cost, and providing great convenience for waste gas treatment.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit the protection scope of the utility model. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
