[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] like Figures 2 to 4 As shown in the figure, a VOCs organic waste gas treatment device according to an embodiment of the present invention includes an anti-clogging mechanism 3. The anti-clogging mechanism 3 includes a plurality of spray chambers 32. A plurality of fixed plates 36 in a ring array are fixedly connected to the opposite surfaces of the plurality of spray chambers 32. A spray inner wall 37 is fixedly connected to the inner side of the spray chambers 32. A cleaning brush handle 23 is slidably connected to the inner side of the spray inner wall 37. A cleaning bristle 24 is fixedly connected below the cleaning brush handle 23. A transmission mechanism 2 is fixedly connected to the end of the cleaning brush handle 23 away from the spray inner wall 37. The transmission mechanism 2 includes a drive motor 22. A drive column 21 is fixedly connected below the drive motor 22. A linear array of cleaning brush handles 23 is fixedly connected to the outer surface of the drive column 21.

[0024] The inner wall 37 of the spray system is fixedly connected to a number of anti-clogging screen plates 31 arranged in a linear array. The surface of the anti-clogging screen plates 31 is provided with a number of filter holes 33 arranged in a ring. The filter holes 33 are all fixedly connected to packing balls 34. The bottom spray cavity 32 is fixedly connected to a mounting base plate 35. The mounting base plate 35 is fixedly connected to a fixing plate 36 on the ring above it. The output end of the mounting base plate 35 is fixedly connected to an air outlet pipe 13. The outer wall of the spray cavity 32 is fixedly connected to the main body of the spray tower device 1. The outer wall of the main body of the spray tower device 1 is fixedly connected to a number of fixing frames 11 arranged in a ring. The middle part of the anti-clogging screen plates 31 is rotatably connected to the outer wall of the drive column. The upper surface of the anti-clogging screen plates 31 is slidably connected to the bottom end of the cleaning brush bristles 24. The cleaning brush bristles 24 are in close contact with the top of the packing balls 34 inside the filter holes 33.

[0025] The problem of impurity accumulation on the anti-clogging screen plate 31 can be solved by the cooperation of the anti-clogging mechanism 3 and the transmission mechanism 2. During use, the drive column 21 is rotated by the output of the drive motor 22, causing the drive column 21 to rotate the cleaning brush handle 23 fixed on the side. The cleaning brush handle 23 then rotates the cleaning bristles 24 below, which slide against the upper surface of the anti-clogging screen plate 31. The cleaning brush handle 23 rotates inside the spray inner wall 37, and the cleaning brush handle 23 drives the cleaning bristles 24 to clean the anti-clogging screen plate 31. This cleans the distilled VO in the spray pipe 14. During the Cs organic waste gas scrubbing process, pollutants combine with the waste gas absorption liquid, causing viscous impurities in the waste gas, such as high-boiling-point organic matter, polymers, and scaling substances such as salt crystals, to easily adhere to the surface of the anti-clogging plate 31. The presence of these impurities hinders the normal contact and mass transfer of gas and liquid on the anti-clogging plate 31, reducing the scrubbing absorption efficiency. The circularly moving cleaning bristles 24 can periodically clean the surface of the anti-clogging plate, removing these accumulated impurities in a timely manner, effectively solving the problem of impurities accumulating on the surface of the tower plate.

[0026] Accumulated impurities may clog the gas-liquid flow channels such as the float valves and sieve holes on the tower plate, affecting the normal flow and mass transfer of gas and liquid between the anti-clogging plate 31. The cleaning action of the cleaning brush 24 can keep these channels unobstructed, ensuring that gas and liquid can have sufficient contact and mass transfer on the anti-clogging plate 31 as required by the design, and maintaining the stable operation of the spray tower.

[0027] like Figure 1 As shown, the main body 1 of the spray tower device has an air inlet pipe 12 fixedly connected to the side input end through the inner and outer walls, an air outlet pipe 13 fixedly connected to the side output end through the inner and outer walls, and a spray pipe 14 fixedly connected to the top input end through the inner and outer walls.

[0028] Working principle: The cooperation of anti-clogging mechanism 3 and transmission mechanism 2 can solve the problem of impurity accumulation in the anti-clogging screen plate 31. During use, the output end of the drive motor 22 drives the drive column 21 to rotate, which in turn drives the cleaning brush handle 23 fixed on the side to rotate. The cleaning brush handle 23 drives the cleaning bristles 24 below to rotate. The cleaning bristles 24 slide against the upper surface of the anti-clogging screen plate 31. The cleaning brush handle 23 rotates on the inner side of the spray inner wall 37, and the cleaning brush handle 23 drives the cleaning bristles 24 to clean the anti-clogging screen plate 31. The cleaning brush handle 23 drives the cleaning bristles 24 to clean the anti-clogging screen plate 31. During the VOCs organic waste gas scrubbing process, pollutants combine with the waste gas absorption liquid, causing viscous impurities in the waste gas, such as high-boiling-point organic matter, polymers, and scaling substances such as salt crystals, to easily adhere to the surface of the anti-clogging plate 31. The presence of these impurities hinders the normal contact and mass transfer of gas and liquid on the anti-clogging plate 31, reducing the scrubbing efficiency. The circularly moving cleaning brush 24 can periodically clean the surface of the anti-clogging plate, removing these accumulated impurities in a timely manner, effectively solving the problem of impurities accumulating on the surface of the tower plate.

[0029] Accumulated impurities may clog the gas-liquid flow channels such as the float valves and sieve holes on the tower plate, affecting the normal flow and mass transfer of gas and liquid between the anti-clogging plate 31. The cleaning action of the cleaning brush 24 can keep these channels unobstructed, ensuring that gas and liquid can have sufficient contact and mass transfer on the anti-clogging plate 31 as required by the design, and maintaining the stable operation of the spray tower.
