When entering the washing layer, the gas distribution is uneven, resulting in local gas flow rates being too large or too small, and no gas passing through some areas, affecting the processing efficiency of the equipment. Long-term operation is prone to local blockage. For this reason, a new technical solution needs to be designed to solve this problem. Utility Model Content

[0011] Compared with the prior art, the beneficial effects of the utility model are:
[0012] 1. The utility model combines an air intake pipe, spiral blades and a uniform support plate. When the exhaust gas enters the tower body from the air intake pipe, the lower part of the air intake pipe is provided with an oblique cut, which facilitates the airflow to blow onto the water reservoir below the tower body. The exhaust gas is reflected by the liquid surface in the water reservoir and enters the spiral blades to rotate and be discharged upward. Then the exhaust gas passes through the uniform support plate to evenly distribute the airflow again, so that the airflow enters the filler spray layer more evenly, thereby achieving uniform airflow distribution, thereby avoiding excessive local airflow that reduces the treatment efficiency and blockage caused by excessive airflow.

The utility model combines the first drive motor, the second drive motor, the screw rod, the slide groove, the slider, the drive ring, the annular groove, the limit block, the drive cylinder, the cleaning rod and the limit mechanism. When the uniformly distributed support disk is blocked, the second drive motor is started to drive the screw rod to rotate. Since the slider is guided and moved in the slide groove, the cleaning rod can be brought into contact with the uniformly distributed support disk. Then the first drive motor is started. Since the drive ring is limited on the limit block through the rotation of the annular groove, the cleaning rod can be driven to rotate in cooperation with the limit mechanism. Since the cleaning rod is an elastic rubber rod, the uniformly distributed support disk is vibrated when the cleaning rod rotates and passes through the through hole on the uniformly distributed support disk, thereby facilitating the cleaning of the uniformly distributed support disk blocked inside the tower body, and further making the cleaning of the uniformly distributed support disk more convenient.

DETAILED DESCRIPTION
[0021] The utility model is further described below in conjunction with the accompanying drawings and embodiments:
[0022] Example 1: A gas distribution device for a scrubbing tower, see Figures 1 to 6, including a tower body 1, one side of the tower body 1 is connected with an air intake pipe 2, and the air intake pipe 2 penetrates the tower body 1 and is placed inside the tower body 1, the lower part of the air intake pipe 2 in the tower body 1 is set with an oblique cut, the inner cavity of the tower body 1 is installed with a uniform support plate 3, and a spiral blade 5 is installed below the uniform support plate 3. When the exhaust gas enters the tower body 1 from the air intake pipe 2, since the lower part of the air intake pipe 2 is set with an oblique cut, it is beneficial for the airflow to blow onto the water reservoir below the tower body 1, so that the exhaust gas is reflected by the liquid surface in the water reservoir and enters the spiral blade 5 to rotate and be discharged upward, and then the exhaust gas passes through the uniform support plate 3 to evenly distribute the airflow again, so that the airflow enters the filling more evenly. The material spraying layer can realize uniform distribution of airflow, thereby avoiding excessive local airflow that reduces processing efficiency and blockage caused by excessive airflow; a driving cylinder 6 is slidably penetrated in the middle of the spiral blade 5, and a cleaning rod 61 is fixedly connected to the top of the driving cylinder 6. There are multiple cleaning rods 61, and multiple cleaning rods 61 are elastic rubber rods. Connecting rods 92 are fixedly connected on both sides of the driving cylinder 6, and a driving ring 9 is fixedly connected between the outer sides of the two connecting rods 92. Slide grooves 11 are provided on both sides of the inner cavity of the tower body 1, and sliders 12 are slidably connected in the two slide grooves 11. The opposite ends of the two sliders 12 are fixedly connected to limited Block 13, an annular groove 91 is provided on the outer side of the driving ring 9, a screw rod 81 is rotatably connected in one of the sliding grooves 11, and the slider 12 is threadedly sleeved on the outer side of the screw rod 81. The bottom of the tower body 1 is installed with a first driving motor 4 and a second driving motor 8. The driving end of the first driving motor 4 is fixedly connected with a rotating rod 41, and a limiting mechanism is installed between the rotating rod 41 and the driving cylinder 6. The limiting mechanism includes limiting grooves 42 provided on both sides of the rotating rod 41 and limiting strips 62 installed on both sides of the inner cavity of the driving cylinder 6. The two limiting strips 62 are respectively slidably connected in the two limiting grooves 42, and the driving end of the second driving motor 8 is connected to the screw rod 81. When the uniformly distributed support When the disk 3 is blocked, the second drive motor 8 is started to drive the screw rod 81 to rotate. Since the slider 12 is guided and moved in the slide groove 11, the cleaning rod 61 can be brought into contact with the uniformly distributed support disk 3. Then the first drive motor 4 is started. Since the drive ring 9 is rotated and limited on the limit block 13 through the annular groove 91, the cleaning rod 61 can be driven to rotate in cooperation with the limit mechanism. Since the cleaning rod 61 is an elastic rubber rod, when the cleaning rod 61 rotates and passes through the through hole on the uniformly distributed support disk 3, the uniformly distributed support disk 3 vibrates, thereby facilitating the cleaning of the uniformly distributed support disk 3 that is blocked inside the tower body 1, and further making the cleaning of the uniformly distributed support disk 3 more convenient.
[0023] For details, see Figure 2 A slide rod 7 is fixedly connected between the upper and lower ends of the inner cavity of another slide groove 11, and a slider 12 is slidably sleeved on the outside of the slide rod 7. The slider 12 slides and guides the movement on the outside of the slide rod 7, thereby improving the stability of the drive ring 9 when moving up and down.
[0024] It is worth noting that see Figure 3 A plurality of air holes 51 are provided on the spiral blade 5, and the plurality of air holes 51 are evenly distributed on the spiral blade 5. While the exhaust gas rotates and rises between the spiral blades 5 through the evenly provided air holes 51, the exhaust gas can be further washed by the detergent dripping from the air holes 51, thereby effectively improving the uniformity and washing efficiency of the exhaust gas.
[0025] It is worth noting that see Figure 2 The maximum connection length between the rotating rod 41 and the driving cylinder 6 is greater than the distance between the uniformly distributed support disk 3 and the bottom end of the inner cavity of the tower body 1, which is used to ensure that the cleaning rod 61 can contact the uniformly distributed support disk 3 to clean the blocked uniformly distributed support disk 3.
