The scrubbing liquid can absorb particulate matter and soluble gases in the exhaust gas. During the washing process, the chemical substances in the scrubbing liquid react with the harmful components in the exhaust gas, such as neutralization reaction and oxidation-reduction reaction, to further remove pollutants. However, the cooling and washing effect of the exhaust gas by spraying is not uniform enough, resulting in the exhaust air quality not meeting the standards. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model;
[0027] Please see Figures 1-5 In this utility model, a high-efficiency high-temperature waste gas scrubbing tower includes a tower body 1. A rotating rod 2 is rotatably connected to the inner wall of the tower body 1. The top end of the rotating rod 2 passes through and extends to the top of the tower body 1. A motor 3 is installed at the top of the tower body 1. The output shaft of the motor 3 is fixedly connected to the rotating rod 2. An air inlet pipe 4 is inserted through and fixedly connected to the bottom of the tower body 1. The bottom end of the rotating rod 2 is hollow. A groove 5 is formed in the inner bottom wall of the tower body 1. The inner wall of the groove 5 is rotatably connected to the rotating rod 2. Two stirring tubes 6 are connected to the bottom end of the rotating rod 2. The bottom of each of the two stirring tubes 6 has an outlet pipe arranged at equal intervals. The tower body 1 has an air vent 7 and a liquid inlet pipe 8 that is fixedly connected to it. A sleeve 9 is fixedly connected to the inner top wall of the tower body 1. The sleeve 9 is fitted onto the rotating rod 2 and is rotatably connected to it. An annular groove 10 is opened on the inner side of the sleeve 9. The top of the rotating rod 2 is hollow. An annularly distributed air inlet 11 is opened at the top of the rotating rod 2. Two horizontal pipes 12 are connected to the top of the rotating rod 2. The bottom of the two horizontal pipes 12 is provided with nozzles 13 arranged at equal intervals. An exhaust pipe 14 is connected to the top of the tower body 1. A drain pipe 15 is connected to the bottom of the tower body 1. A water pump 16 is installed on the drain pipe 15.
[0028] In this invention, during use, exhaust gas enters the groove 5 through the inlet pipe 4, then enters the rotating rod 2, and is discharged into the washing liquid inside the tower body 1 through the outlet 7 on the stirring pipe 6. The exhaust gas is then cleaned and cooled by the washing liquid before floating out. Prior to this, the washing liquid is injected through the inlet pipe 8, enters the sleeve 9, and then enters the top of the rotating rod 2 through the annular groove 10 and the inlet 11. The washing liquid is then sprayed out through the nozzles 13 at the bottom of the two horizontal pipes 12. The sprayed washing liquid replenishes the washing liquid in the tower body 1 and comes into contact with the exhaust gas, further cooling and cleaning it, thus effectively improving the cleaning effect. The secondary treatment of the washing liquid... The liquid will be discharged from the exhaust pipe 14, completing the washing of the exhaust gas. During the entire washing process, the user turns on the motor 3, which drives the rotating rod 2 to rotate. During this process, the rotating rod 2 drives the stirring tube 6 to stir the washing liquid in the tower body 1. Stirring allows the exhaust gas and washing liquid to come into better contact, thereby improving the washing and cooling effect of the exhaust gas. Moreover, the rotation of the stirring tube 6 changes the position of the exhaust gas entering the washing liquid, further allowing the exhaust gas and washing liquid to come into even contact, thereby improving the treatment effect of the exhaust gas. At the same time, the rotating rod 2 drives the horizontal tube 12 to rotate, thereby changing the orientation of the nozzle 13, so that the washing liquid sprayed from the nozzle 13 can be evenly sprayed in the tower body 1, further improving the uniformity of the washing and cooling of the exhaust gas.
[0029] Please see Figure 3 Two filter plates 17 are fixedly connected to the rotating rod 2, and the two filter plates 17 are located in the middle of the rotating rod 2.
[0030] In this invention, the rotating rod 2 drives the filter plate 17 to rotate during rotation. The filter plate 17 can capture particulate matter in the exhaust gas during rotation, thereby reducing the difficulty of washing the exhaust gas with the sprayed washing liquid and improving the washing effect of the exhaust gas.
[0031] Please see Figures 1-3 Among them: a gas sensor 18 is installed on the exhaust pipe 14, a vertical pipe 19 connects the exhaust pipe 14 and the intake pipe 4, a one-way valve 20 is installed on both the vertical pipe 19 and the exhaust pipe 14, and an air pump 21 is installed on the vertical pipe 19.
[0032] In this invention, the gas sensor 18 can detect the quality of the exhaust air. If the detected air quality does not meet the standards, the air pump 21 will be turned on. The air pump 21 will re-enter the treated exhaust gas into the intake pipe 4 through the vertical pipe 19 for secondary treatment of the exhaust gas until the exhaust gas is treated to meet the appropriate emission standards before being discharged.
[0033] Please see Figure 3The drain pipe 15 is fitted with a box 22 fixedly connected to the right end. A filter box 23 is slidably connected to the front of the box 22. A conduit 24 is connected to the right side of the box 22. A connecting pipe 29 is connected to the right end of the box 22. A square box 25 is fixedly connected to the top of the connecting pipe 29. Cooling chips 26 are installed on both the front and back of the square box 25. The heat dissipation ends of the two cooling chips 26 are located on the outside of the square box 25. The heat absorption ends of the two cooling chips 26 penetrate and extend into the interior of the square box 25. A return water pipe 27 is connected to the left side of the square box 25. The left end of the return water pipe 27 penetrates and extends into the interior of the tower body 1.
[0034] In this invention, the water pump 16 can extract the washing liquid that has grown in the tower body 1. The extracted washing liquid is filtered by the filter box 23. The filtered washing liquid is discharged into the recovery system through the conduit 24, thereby maintaining the washing liquid at a suitable water level. During the extraction of the washing liquid, the filtered washing liquid can enter the connecting pipe 29. The washing liquid will enter the square box 25 from the connecting pipe 29. The cooling plate 26 in the square box 25 will cool the washing liquid. The cooled washing liquid will re-enter the tower body 1 from the return water pipe 27, thereby cooling the washing liquid inside the tower body 1 and improving the cooling effect on the exhaust gas.
[0035] Please see Figure 3 Among them, the left end of the return water pipe 27 is fixedly connected to the nozzle 28.
[0036] In this invention, the nozzle 28 fixedly connected to the left end of the return water pipe 27 allows the cooled washing liquid to be evenly sprayed into the tower body 1, thereby assisting in the cooling and washing of the exhaust gas and further improving the efficiency of the device in cooling and washing the exhaust gas.
[0037] The above are merely preferred embodiments of this utility model; however, the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and its improved concept, should be included within the scope of protection of this utility model.
