Sulfur dioxide and acid mist are known as the main culprits of air pollution and have a very great impact on human health and the ecological system, so sufficient attention must be paid. At present, for environmental purification, polluted gases will be treated. When treating polluted gases, some solid impurities will be adsorbed on the inner wall of the tail gas absorption tower. In order to reduce the impact on the service life of the tail gas absorption tower, there has emerged on the market a method of using a rotating cleaning plate to clean the inner wall of the tail gas absorption tower, so that solid impurities will not adhere to the inner wall of the tail gas absorption tower.

[0003] The existing technology has the following problems:

[0004] After a large number of searches, it is found that the patent document with the application number CN202122252456.5 discloses a tail gas absorption tower with a self-cleaning function. The above patent still has problems in actual use. More obviously, the method of using a rotating arc-shaped cleaning plate and a square cleaning plate to clean the inner wall of the lower tower. After multiple uses, the arc-shaped cleaning plate and the square cleaning plate will be worn due to friction. After wear, there will be gaps between the arc-shaped cleaning plate and the square cleaning plate and the inner wall of the lower tower, thus affecting the cleaning effect of the solid impurities on the inner wall of the lower tower.

[0025] Please refer to Figures 1-4 , an absorption tower with a self-cleaning function, including a lower tower 1 and an upper tower 2. The upper tower 2 is detachably installed on the lower tower 1, and a cleaning component 3 is installed on the upper tower 2.

[0026] In this embodiment: The cleaning component 3 includes a driving motor 31, a support frame 32, a servo motor 33, a lead screw 34, a support plate 35, a guide rod 36, a rotating rod 37, a stirring rod 38, a sliding groove 39, a centrifugal rod 310, and a cleaning plate 311. Support plates 35 are fixedly installed on both sides of the top surface of the upper tower 2, and a servo motor 33 and a guide rod 36 are respectively installed on the side surfaces of the two support plates 35 close to each other. A lead screw 34 is installed at the output end of the servo motor 33. A support frame 32 is used in cooperation with both the guide rod 36 and the lead screw 34, and a driving motor 31 is installed on the support frame 32. A rotating rod 37 is installed at the output end of the driving motor 31, and a stirring rod 38 is fixedly connected to the surface of the rotating rod 37. A sliding groove 39 is opened at the end of the stirring rod 38, and a centrifugal rod 310 is slidably connected inside the sliding groove 39. A cleaning plate 311 is installed at one end of the centrifugal rod 310, and the surface of the cleaning plate 311 is attached to the inner wall of the lower tower 1.

[0027] Specifically, during use, first add a sufficient amount of chemical reagent into the interior of the lower tower 1 through the water inlet pipe 4, then let the polluted gas enter the interior of the lower tower 1 through the air inlet pipe 5, and then turn on the drive motor 31. The drive motor 31 can drive the rotating rod 37 to rotate, thereby driving the stirring rod 38 on the rotating rod 37 to rotate, so that the chemical reagent and the polluted gas are fully mixed. When the rotating rod 37 rotates, the centrifugal rod 310 is thrown outwards from the chute 39 opened on the surface of the stirring rod 38 under the action of centrifugal force, and the cleaning plate 311 at one end of the centrifugal rod 310 is closely attached to the inner wall of the lower tower 1, achieving the effect of self-cleaning the solid impurities on the inner wall of the lower tower 1, preventing gaps from being generated between the cleaning plate 311 and the lower tower 1, ensuring the cleaning ability of the solid impurities on the inner wall of the lower tower 1, and not easily causing the problem of solid impurities remaining on the inner wall of the lower tower 1. Among them, the forward and reverse rotation of the lead screw 34 converts the rotational motion into a linear motion and drives the cleaning plate 311 to move up and down, which can expand the self-cleaning range of the inner wall of the lower tower 1 and further improve the cleaning effect of the solid impurities on the inner wall of the lower tower 1.

[0028] In this implementation scheme: a control panel 7 is fixedly installed on the outer wall of the lower tower 1, and the control panel 7 is electrically connected to the drive motor 31 and the servo motor 33 through wires.

[0029] Specifically, it is a common circuit connection structure, which is commonplace for those skilled in the art and will not be elaborated here.

[0030] In this implementation scheme: the centrifugal rod 310 is made of an aluminum alloy tube, and the diameter of the centrifugal rod 310 is smaller than the diameter of the chute 39.

[0031] Specifically, it reduces its own weight to ensure that the centrifugal rod 310 can be smoothly thrown outwards under the action of centrifugal force.

[0032] In this implementation scheme: a drain valve is installed on the drain pipe 6.

[0033] Specifically, it can control the opening and closing of the drain pipe 6.

[0034] In this implementation scheme: legs are fixedly installed on the bottom surface of the lower tower 1, and there are several legs.

Only its use is carried out without modification, so the control method and circuit connection will not be described in detail.

[0037] Working principle: When in use, first add a sufficient amount of chemical reagent into the interior of the lower tower 1 through the water inlet pipe 4, then let the polluted gas enter the interior of the lower tower 1 through the air inlet pipe 5, and then turn on the drive motor 31. The drive motor 31 can drive the rotating rod 37 to rotate, thereby driving the stirring rod 38 on the rotating rod 37 to rotate, so that the chemical reagent and the polluted gas are fully mixed. When the rotating rod 37 rotates, the centrifugal rod 310 is thrown outwards from the sliding groove 39 formed on the surface of the stirring rod 38 under the action of centrifugal force, and the cleaning plate 311 at one end of the centrifugal rod 310 is closely attached to the inner wall of the lower tower 1, achieving the effect of self-cleaning the solid impurities on the inner wall of the lower tower 1, preventing a gap from being generated between the cleaning plate 311 and the lower tower 1, ensuring the cleaning ability of the solid impurities on the inner wall of the lower tower 1, and not easily causing the problem that solid impurities remain on the inner wall of the lower tower 1. Among them, the forward and reverse rotation of the lead screw 34 converts the rotational motion into a linear motion and drives the cleaning plate 311 to move up and down, which can expand the self-cleaning range of the inner wall of the lower tower 1 and further improve the cleaning effect of the solid impurities on the inner wall of the lower tower 1. Moreover, the solid impurities cleaned off can be discharged along with the liquid through the drain pipe 6. It has strong practicability and is worthy of promotion.

[0038] It should be noted that: The model specifications of the control panel 7, the drive motor 31, and the servo motor 33 need to be selected and determined according to the actual specifications of the device, etc. The specific selection calculation method adopts the existing technology in this field, so it will not be elaborated in detail.

[0039] The power supply and its principle of the control panel 7, the drive motor 31, and the servo motor 33 are clear to those skilled in the art, and will not be described in detail here.

[0040] The above is only the preferred specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto.
