[0023] Please refer to Figure 1 and Figure 4 , and a tail gas treatment device provided by the present invention will be described hereinafter. The tail gas treatment device includes a spray tank 1, a plurality of spray heads 2, a gas transmission pipe 3, a sedimentation tank 41, an intake pipe 48, and an exhaust pipe 5. A plurality of spray heads 2 are located inside the spray tank 1 and are fixedly connected to the spray tank 1. The gas transmission pipe 3 penetrates the side wall of the spray tank 1 so that one end of the gas transmission pipe 3 is located inside the spray tank 1. The gas transmission pipe 3 is fixedly connected to the spray tank 1 and is located below the spray heads 2. The sedimentation tank 41 is arranged on the ground on one side of the spray tank 1. The intake pipe 48 is vertically arranged, and the lower end of the intake pipe 48 is located inside the sedimentation tank 41. The intake pipe 48 is fixedly connected to the sedimentation tank 41. One end of the exhaust pipe 5 communicates with the top inside the spray tank 1, and the other end is used to communicate with the upper end of the intake pipe 48. One end of the water outlet pipe 42 is fixedly connected to the spray tank 1 and communicates with the bottom of the spray tank 1.

[0024] Compared with the prior art, in the tail gas treatment device provided by the present invention, an alkaline solution is placed in the sedimentation tank 41, and the spray heads 2 are used to spray the alkaline solution, so that the waste gas enters the spray tank 1 through the gas transmission pipe 3. The spray heads 2 spray the alkaline solution on the waste gas, and the waste gas after spraying floats out of the spray tank 1 through the exhaust pipe 5, and then enters the sedimentation tank 41 through the intake pipe 48 and overflows from the sedimentation tank 41 after being washed by the alkaline solution in the sedimentation tank 41. The alkaline solution sprayed by the spray heads 2 and the alkaline solution in the sedimentation tank 41 can react with the chlorine in the tail gas twice, thereby avoiding the problem that the treatment effect of only using spraying to treat the chlorine in the tail gas is limited.

[0025] In this embodiment, a liquid injection pipe 240 is provided on the spray head 2. The liquid injection pipe 240 penetrates the top wall of the spray tank 1 and is fixedly connected to the top wall of the spray tank 1. The spray head 2 is fixedly connected to the spray tank 1 through the liquid injection pipe 240. An alkaline solution is injected into the liquid injection pipe 240 and then sprayed out through the spray head 2.

[0026] In some embodiments, referring to Figure 4 , the tail gas treatment device further includes a water outlet pipe 42. One end of the water outlet pipe 42 is fixedly connected to the spray tank 1 and communicates with the bottom of the spray tank 1. The other end of the water outlet pipe 42 is located directly above the sedimentation tank 41. In the prior art, the waste liquid formed after the alkaline solution sprayed by the spray head 2 contacts the tail gas still contains unreacted alkaline substances, and if not utilized, it will cause waste of alkaline substances. In this embodiment, the formed waste liquid can flow into the sedimentation tank 41 through the water outlet pipe 42. Thus, the chlorine gas in the tail gas entering the sedimentation tank 41 can continue to react with the alkaline substances in the waste liquid, thereby avoiding waste of alkaline substances.

[0027] In some embodiments, referring to Figure 4 and Figure 5 , the sedimentation tank 41, the air inlet pipe 48 and the water outlet pipe 42 are combined into a treatment unit. The number of treatment units is multiple, and the multiple treatment units are evenly distributed around the spray tank 1. The treatment unit further includes a valve 43. The valve 43 is provided at the other end of the water outlet pipe 42. Wherein, one end of the air outlet pipe 5 can rotatably penetrate the top wall of the spray tank 1, and the rotation of the air outlet pipe 5 enables the other end of the air outlet pipe 5 to be sequentially communicated with the upper ends of each air inlet pipe 48. The initial state of the valve 43 is in the closed state. The waste liquid formed after the alkaline solution sprayed by the spray head 2 contacts the tail gas is at the bottom of the spray tank 1. One of the treatment units can be named the first treatment unit, and the adjacent treatment unit is the second treatment unit. When the other end of the air outlet pipe 5 is communicated with the upper end of the air inlet pipe 48 in the first treatment unit, the tail gas enters the sedimentation tank 41 where the air inlet pipe 48 is located for reaction. After reacting for a period of time, the input of waste gas into the gas transmission pipe 3 is paused, the valve 43 in the second treatment unit is opened, so that the waste liquid in the spray tank 1 flows into the sedimentation tank 41 in the second treatment unit. Then the air outlet pipe 5 rotates so that the other end of the air outlet pipe 5 is communicated with the upper end of the air inlet pipe 48 in the second treatment unit, and then the waste gas is continuously input into the gas transmission pipe 3 and the valve 43 in the second treatment unit is closed, and the waste gas enters the sedimentation tank 41 in the second treatment unit for reaction. The waste liquid in the sedimentation tank 41 in the first treatment unit is subjected to sedimentation treatment.

[0028] Further, the gas delivery pipe 3 has a fourth vertical section 31 arranged vertically, and the fourth vertical section 31 is located inside the spray tank 1. One end of the gas delivery pipe 3 inside the spray tank 1 is located on the fourth vertical section 31 and is the lower end of the fourth vertical section 31. In this way, when the waste liquid overflows the lower end of the fourth vertical section 31, the tail gas first contacts the waste liquid in the spray tank 1 and then is sprayed, thereby further improving the effect of tail gas treatment.

[0029] Further, the treatment unit further includes a position post 47. One end of the position post 47 is fixedly connected to the air inlet pipe 48, and the other end is fixedly connected to the side wall of the sedimentation tank 41. The air inlet pipe 48 is fixedly connected to the sedimentation tank 41 through the position post 47. By reasonably setting the length, orientation, etc. of the position post 47, the air inlet pipe 48 can be fixed at a suitable position inside the sedimentation tank 41.

[0030] In some embodiments, referring to Figure 4 and Figure 7 , the outlet pipe 5 has a first vertical section 51 arranged vertically. The first vertical section 51 is coaxially arranged with the rotation axis of the outlet pipe 5. The tail gas treatment device further includes a positioning ring 6, an annular member 7, and a fixing post 8. The positioning ring 6 is sleeved and fixed outside the first vertical section 51. An annular groove 71 is provided on the inner side wall of the annular member 7, and the annular member 7 is sleeved outside the positioning ring 6 through the annular groove 71. There are several fixing posts 8, and the fixing posts 8 are fixedly arranged on the spray tank 1 and fixedly connected to the annular member 7. The annular member 7 is fixedly connected to the spray tank 1 through the fixing posts 8. The annular member 7 restricts the movement of the first vertical section 51 in the vertical direction through the positioning ring 6.

[0031] In this embodiment, a third gasket 250 may be sleeved on the first vertical section 51, and the third gasket 250 is fixedly attached to the top wall of the spray tank 1 to prevent the tail gas from escaping between the top wall of the spray tank 1 and the first vertical section 51.

[0032] In some embodiments, referring to Figure 1 and Figure 2 , the outlet pipe 5 has a second vertical section 52 arranged vertically. The second vertical section 52 is located above the air inlet pipe 48. The rotation of the outlet pipe 5 enables the second vertical section 52 to be coaxially aligned with each air inlet pipe 48 in sequence. The tail gas treatment device further includes a sliding pipe 9. The sliding pipe 9 is slidably sleeved outside the second vertical section 52. Among them, when the second vertical section 52 is coaxially aligned with one of the air inlet pipes 48, the sliding pipe 9 can be slidably sleeved outside the air inlet pipe 48. The outlet pipe 5 is communicated with the upper end of the air inlet pipe 48 through the sliding pipe 9, and at the same time, the air inlet pipe 48 can restrict the rotation of the outlet pipe 5 through the sliding pipe 9.

[0033] In some embodiments, referring to Figure 2, the tail gas treatment device further includes a drive shaft 100, a limiting member 110, and a connecting shaft 120.

The limiting member 110 is provided with a limiting hole 1101 which is elongated and vertically arranged in the length direction. The limiting member 110 is sleeved outside the drive shaft 100 through the limiting hole 1101. The two ends of the connecting shaft 120 are respectively fixedly connected to the second vertical section 52 and the limiting member 110. In this way, the sliding of the sliding tube 9 can be controlled by the drive shaft 100. The limiting member 110 is fixedly connected to the intake pipe 48 through the connecting shaft 120. The limiting member 110 can limit the self-rotation of the sliding tube 9 through the drive shaft 100, so as to prevent the drive shaft 100 from rotating with the sliding tube 9 to an inconvenient operating position. At the same time, the limiting of the drive shaft 100 through the limiting hole 1101 can prevent the sliding tube 9 from sliding downward and disengaging from the second vertical section 52.

[0034] In some embodiments, referring to Figure 2 and Figure 6 , the tail gas treatment device further includes a placement shaft 130 and a compression spring 140. The placement shaft 130 is located in the limiting hole 1101. The placement shaft 130 is vertically arranged, and the upper end and the lower end of the placement shaft 130 are respectively fixedly connected to the top wall and the bottom wall of the limiting hole 1101. The placement shaft 130 slidably penetrates the drive shaft 100. The compression spring 140 is sleeved outside the placement shaft 130, and the two ends of the compression spring 140 respectively abut against the drive shaft 100 and the top wall of the limiting hole 1101. When the sliding tube 9 slides and is sleeved on one of the intake pipes 48, the resilience of the compression spring 140 can increase the resistance for the sliding tube 9 to slide and disengage from the intake pipe 48.

[0035] In some embodiments, referring to Figure 2 , the processing unit further includes a first support ring 44 and a first gasket 45. The first support ring 44 is sleeved and fixed outside the intake pipe 48. The first gasket 45 is sleeved outside the intake pipe 48 and is fixedly attached to the first support ring 44. Among them, when the sliding tube 9 slides and is sleeved outside the intake pipe 48, the sliding tube 9 can downwardly press the first gasket 45. When the sliding tube 9 slides and is sleeved on one of the intake pipes 48, the sliding tube 9 can press downward on the first gasket 45, and the resilience of the compression spring 140 can cause the sliding tube 9 to tightly press the first gasket 45 downward, so as to ensure the seal between the sliding tube 9 and the intake pipe 48.

[0036] Further, a fourth gasket 260 can be slidably sleeved on the second vertical section 52, and the fourth gasket 260 is fixedly attached to the sliding tube 9, so as to ensure the seal between the sliding tube 9 and the second vertical section 52.

The second supporting ring 180 is sleeved and fixed outside the third vertical section 1701. The second gasket 190 is sleeved outside the third vertical section 1701 and is fixedly attached to the second supporting ring 180. The U-shaped pipe 200 has two parallel connecting sections 2001, and the two connecting sections 2001 are respectively used for slidingly sleeving outside the third vertical section 1701 and one of the intake pipes 48, so that the two connecting sections 2001 can respectively press down the second gasket 190 and the first gasket 45 on the intake pipe 48. When the waste liquid in one of the sedimentation tanks 41 is completely sedimented, there is silt at the bottom of the sedimentation tank 41, and there is supernatant liquid above the silt. The moving vehicle body 150 can move to a suitable position near the sedimentation tank 41, and then the two connecting sections 2001 are respectively slidingly sleeved outside the third vertical section 1701 and the intake pipe 48 in the sedimentation tank 41, and the two connecting sections 2001 respectively press down the second gasket 190 and the first gasket 45 on the intake pipe 48, so as to ensure the sealing between the third vertical section 1701 and the U-shaped pipe 200 and between the intake pipe 48 and the U-shaped pipe 200. Then the water pump 160 can extract the supernatant liquid in the sedimentation tank 41 through the water suction pipe 170, the U-shaped pipe 200 and the intake pipe 48, and then the silt in the sedimentation tank 41 can be cleaned up.
