The spray liquid in the spray tower is recycled through a circulating water pump, which can effectively reduce the waste of water resources.

[0003] In actual use, since the waste gas often contains a large amount of impurities, the sprinkler head will inevitably be clogged. Generally, the clogged sprinkler head is cleaned manually regularly. Especially when dealing with viscous waste gas, the waste gas impurities are very easy to clog the sprinkler head, resulting in a shorter cleaning cycle. Frequent cleaning of the sprinkler head has a great impact on work efficiency. Utility Model Content

[0004] Based on the above description, the utility model provides an anti-blocking exhaust gas spray tower to solve the shortcomings of the existing spray tower that it is easy to be blocked due to impurities contained in the exhaust gas, and after being blocked, it is mostly manually cleaned regularly, thus affecting the work efficiency.

[0005] The utility model is realized through the following technical solutions:

[0021] In order to facilitate understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. Embodiments of the present application are provided in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0023] Combination Figure 1-4 As shown, an anti-blocking exhaust gas spray tower comprises:

[0024] The tower body 1 is a rectangular structure with an opening on the surface, the opening extends inward and a slide groove is formed on the inner wall thereof, and an air outlet pipe 23, an air inlet pipe 11 and a recovery pipe 12 are respectively provided on the top and bottom thereof;

[0025] The cooling box 2 is arranged on the outer wall of the tower body 1 and is located directly above the air inlet pipe 11 and is connected to the air inlet pipe 11 through the air delivery pipe. It is mainly used for preliminary cooling and filtering of the exhaust gas.

[0026] The cleaning element 3 is movably inserted into the opening of the tower body 1 and is mainly used for secondary cleaning of the exhaust gas;

[0027] The water pump 6 is arranged below the tower body 1 and is connected to the recovery pipe 12. It is also connected to the water tank, the cooling box 2 and the cleaning part 3 through the water pipe, so as to achieve the purpose of recycling the water resources at the bottom of the tower body 1.

[0028] Specifically, a plurality of spray pipes 21 are arranged side by side inside the cooling box 2, and an atomizing nozzle 22 can be detachably installed on the outer wall of each spray pipe 21. At the same time, the head and tail of the plurality of spray pipes 21 are interconnected to form a mesh pipeline.

[0029] The atomizing nozzles 22 should all adopt two-fluid atomizing nozzles and be arranged vertically downward. Therefore, it is also necessary to set up multiple air pipes 23 inside the cooling box 2. The tail ends of the multiple air pipes 23 are interconnected and extend to the outside of the cooling box 2 to connect with the air pump 4. The air pump 4 should be directly set on the outer wall of the cooling box 2. The other end of the multiple air pipes 23 is connected to each atomizing nozzle 22 in turn, so as to quickly produce a large amount of water mist.

[0030] In addition, in this embodiment, the two-fluid atomizing nozzle can also be replaced by an ultrasonic atomizing nozzle or other structures. As long as the water can be refined into a mist, the replacement can be adaptively performed.

[0031] An exhaust fan is also provided at the other end of the air intake pipe 11, which quickly inputs the exhaust gas into the tower body 1, thereby forming a negative pressure effect inside the air intake pipe 11. Since the two are interconnected, a large amount of water mist in the cooling box 2 will be drawn into the air intake pipe 11 and finally merged into the tower body 1.

[0032] During the above-mentioned gathering process, water mist will quickly mix into the exhaust gas and perform preliminary cooling treatment on the exhaust gas. At the same time, some impurities in the exhaust gas will gradually approach the nearby water mist particles and eventually gather into larger particles of impurities so that they can be quickly purified after entering the tower body 1.

[0033] The cleaning part 3 is composed of three components: a fixed frame 31, a packing layer 32 and a water seepage pipe 33. The fixed frame 31 is a rectangular frame, which is slidably inserted into the inside of the slide groove. The packing layer 32 is detachably installed at the center of the fixed frame 31 so that it can just cover the cross-section of the tower body 1. A cover plate 34 is also provided on the top surface of the packing layer 32. The cover plate 34 is detachably fixedly connected to the fixed frame 31. At the same time, the cover plate 34 is arranged in a mesh structure, and the four sides are locked and fixed to the top surface of the fixed frame 31 by bolts. The water seepage pipe 33 is arranged inside the cover plate 34 and the fixed frame 31, and one end of the water seepage pipe is connected to the center of the end face of the cover plate 34, and the other end extends to the center of the fixed frame 31 and extends outward. Finally, an interface is formed at the center of the end face of the outward end of the fixed frame 31, and the interface is connected to the water pipe.

[0034] The top surface of the cover plate 34 is also provided with a large number of seepage holes 35, which are arranged in a rectangular array, and a protective cover 36 is provided at the top of each seepage hole 35. The protective cover 36 is arc-shaped and supported by a transparent acrylic plate, and a gap is left between the inner arc surface and the port of the seepage hole 35. When external water is discharged through the seepage hole 35, it will be blocked and flow downward along its arc surface, and finally flow into the inside of the packing layer 32 along the surface of the cover plate 34 with its mesh structure.

[0035] A large number of ball rings or Raschig rings made of plastic are arranged inside the packing layer 32. When water enters these packings, a water film will be formed on their surface. When the exhaust gas at the bottom flows upward, the impurities in the exhaust gas will be captured by these water films and finally gathered at the bottom of the tower body 1, while the clean air will flow upward and finally be discharged to the outside of the tower body 1.

[0036] At the same time, the service life of the packing layer 32 should also be taken into consideration. Therefore, a pull-out plate needs to be provided on the outward side of the fixed frame 31. In addition, a sealing groove should be arranged on the surface of the tower body 1 near the opening in consideration of the sealing performance of the equipment. Flanges are provided on the four sides of the outward side of the fixed frame 31. The flanges protrude toward the tower body 1 to form an insert plate. The insert plate is plugged and fixed to the sealing groove, and the surface of the flange is arranged flush with the surface of the tower body 1.

[0037] The waste water recovered in the recovery pipe 12 contains a large amount of impurities, so a filter 5 should be set at the bottom of the tower body 1 to communicate with the recovery pipe 12 to prevent the recovered liquid from affecting the normal use of the nozzle.

[0038] In the two structures of the cleaning part 3 and the cooling box 2, the water pressures required by the two are different, so flow regulating valves that can adjust the water pressure should be used on the water pipes of the two to control them respectively to ensure that the water in the pipeline can be circulated normally.

[0039] 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 it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solution recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solution from the technical solution of the embodiments of the utility model.
