When treating the waste gas, the solid particle impurities in the waste gas will be sprayed first, so a scrubbing tower will be used. When the existing scrubbing tower is in use, most of the spray heads are installed on the top of the tower, and then the waste gas is introduced into the tower and sprayed. However, such a spraying method is inconvenient for continuously spraying the waste gas. Therefore, the waste gas needs to be re-introduced into the tower for secondary spraying, which reduces the efficiency of spraying the waste gas. At the same time, when spraying the organic waste gas, it is inconvenient to separate the spraying liquid from the solid particle impurities and recycle the spraying liquid, making the spraying treatment of the organic waste gas more wasteful.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.
[0020] Please refer to Figures 1-4 , the present utility model provides an organic waste gas scrubbing tower for automobile painting, including a tower body 1. The upper surface of the tower body 1 is fixedly connected with an intake pipe 2. A side opening 3 is provided on the side of the tower body 1. A slag collection box 4 is fixedly connected below the port of the side opening 3. A spray pump body 5 is fixedly connected to the side of the tower body 1. A flushing pump body 6 and a conduit 7 are fixed to the front of the tower body 1. A right guide plate 8 is fixedly connected to the right inner wall of the tower body 1. A left guide plate 9 is fixedly connected to the left inner wall of the tower body 1. A lower filter screen 10 is fixedly connected to the upper side inside the tower body 1. A lower inclined plate 11 is fixedly connected to the lower side inside the tower body 1;
[0021] The gap between the right guide plate 8 and the left inner wall of the tower body 1 forms a left through-port 12, and the gap between the left guide plate 9 and the right inner wall of the tower body 1 forms a right through-port 13. Filter grooves 14 are formed on the surfaces of the right guide plate 8 and the left guide plate 9. Guide plate inner cavities 15 are formed inside the right guide plate 8 and the left guide plate 9. An inner filter plate 16 is fixedly connected inside the guide plate inner cavity 15. The gap between the inner filter plate 16 and the inner top surface of the guide plate inner cavity 15 forms a slag discharge cavity 17, and the gap between the inner filter plate 16 and the inner bottom surface of the guide plate inner cavity 15 forms a drainage cavity 18. A flushing head 19 is fixed to the side of the slag discharge cavity 17. A pipe network 20 is fixed inside the right guide plate 8 and the left guide plate 9. Spraying heads 21 are fixed to the bottom surfaces of the right guide plate 8 and the left guide plate 9. Organic waste gas can be introduced into the tower body 1 through the intake pipe 2. The waste gas can be guided by the right guide plate 8 to flow leftward through the left through-port 12 and then downward, and then the waste gas can be guided by the left guide plate 9 to flow leftward through the right through-port 13 and then downward, so as to treat the waste gas in a thickness-wise manner.
[0022] Further, the pipe network 20 is composed of water pipes arranged in the left-right direction and water pipes arranged in the front-back direction. One end of the pipe network 20 is connected to the spraying head 21, and the other end of the pipe network 20 is connected to the spraying pump body 5.
[0023] Further, the flushing head 19 is located inside the slag discharge cavity 17 and is inclined along the inner bottom surface of the slag discharge cavity 17. The flushing head 19 is connected to the flushing pump body 6 through a built-in conduit. The flushing pump body 6 can convey clean water into the flushing head 19, and the flushing head 19 can suck the solid impurities inside the slag discharge cavity 17 into the slag collection box 4.
[0024] Further, the inner filter plate 16 is inclined. The outer end of the inner filter plate 16 penetrates through the side opening 3 and extends into the slag collection box 4. The slag discharge cavity 17 and the drainage cavity 18 are inclined. Through holes are formed on the inner bottom surface of the drainage cavity 18, so that the solid impurities inside the slag discharge cavity 17 can be washed into the slag collection box 4 through the inner filter plate 16, and the solid impurities can be centrally collected.
[0025] Further, two groups of the right guide plate 8 and the left guide plate 9 are provided, and the right guide plate 8 and the left guide plate 9 are arranged in a staggered manner in the up-down direction. Organic waste gas can be introduced into the tower body 1 through the intake pipe 2, and the waste gas can flow downward in the left through-port 12 and the right through-port 13. The waste gas can flow downward in a snake shape through the left through-port 12 and the right through-port 13, so as to increase the flow stroke of the waste gas, and thus the waste gas can be continuously sprayed and treated.
[0026] Further, the lower filter screen 10 is inclined with the right side higher and the left side lower, and the lower inclined plate 11 is inclined with the left side higher and the right side lower. Side openings 3 are provided at both the left end of the lower filter screen 10 and the right end of the lower inclined plate 11. Through the lower filter screen 10, the solid impurities in the spraying liquid can be filtered again and discharged through the side openings 3 at this position. Through the lower inclined plate 11, the spraying liquid can be led outwards and discharged through the side openings 3 at this position.
[0027] During use, the organic waste gas can be introduced into the tower body 1 through the intake pipe 2. As shown in the attached drawings of the specification Figure 4 The waste gas can flow leftwards through the left through-port 12 and then downwards under the guidance of the right guide plate 8, and then the waste gas can flow leftwards through the right through-port 13 and then downwards under the guidance of the left guide plate 9. Therefore, the waste gas can flow in a snake-like shape inside the tower body 1, so that the flow path of the waste gas inside the tower body 1 can be increased for subsequent continuous spraying treatment of the waste gas. During the flow of the waste gas, the spraying liquid can be conveyed into the spray head 21 through the spraying pump body 5 and the pipe network 20, and the spraying liquid can spray the waste gas flowing in a snake-like shape on the right guide plate 8 and the left guide plate 9. Therefore, the waste gas can be continuously sprayed to improve the effect of spraying treatment of the waste gas. The sprayed spraying liquid falls on the right guide plate 8 and the left guide plate 9 and enters the guide plate inner cavity 15 through the filter groove 14. The inner filter plate 16 can filter the solid impurities in the spraying liquid, and the filtered solid impurities remain in the slag discharge cavity 17. The filtered spraying liquid enters the drainage cavity 18 and flows out through the through-holes on the bottom surface of the drainage cavity 18 and is led out by the lower inclined plate 11. And when the spraying treatment of the waste gas is completed, the cleaning water can be conveyed into the cleaning head 19 through the cleaning pump body 6. Therefore, the cleaning head 19 can wash the impurities inside the slag discharge cavity 17 obliquely downwards. And during the movement of the solid impurities inside the slag discharge cavity 17, the cleaning water can enter the drainage cavity 18 and then be discharged. The impurities inside the slag discharge cavity 17 can enter the slag collection box 4. Therefore, the spraying liquid and the solid impurities can be classified and collected.
