[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods. Embodiment 1

[0019] like Figure 1-Figure 3 As shown, this embodiment discloses a complex exhaust gas comprehensive treatment system, including a cylinder 1, an air inlet pipe 3 is provided at the middle and lower part of the outer surface of the cylinder 1, the air inlet pipe 3 extends into the cylinder 1 at one end close to the cylinder 1 and is provided with a mounting cylinder 4, and the mounting cylinder 4 is connected with the air inlet pipe 3, a rotating tube 10 is provided in the middle of the inner cavity bottom wall of the mounting cylinder 4, and a rotating impeller 9 for rotating by the air flow blown out of the air inlet pipe 3 is provided on the outer surface of the rotating tube 10, the upper end of the rotating tube 10 extends to the outside of the mounting cylinder 4 and is provided with an interception treatment component 6 for improving the exhaust gas treatment effect, the interception treatment component 6 is similar to the packing layer in the exhaust gas spray treatment, the upper part of the inner cavity of the cylinder 1 is provided with an atomizing nozzle component 7 for spraying and neutralizing the exhaust gas liquid, and the bottom of the cylinder 1 is also provided with an environmental protection water tank, which is a conventional design in the prior art, so it is not described; Specifically, Figure 3 As shown, the interception processing assembly 6 is composed of a supporting filter plate 1 61 and a supporting filter plate 2 62. The supporting filter plate 1 61 and the supporting filter plate 2 62 are close to each other and do not contact each other. The inner sides of the supporting filter plate 1 61 and the supporting filter plate 2 62 are filled with fillers for increasing the gas-liquid contact area. The supporting filter plate 1 61 is fixedly connected to the inner wall of the cylinder 1, the supporting filter plate 1 61 is sleeved on the outer side of the rotating tube 10 and is rotatably connected to the rotating tube 10, and the supporting filter plate 2 62 is fixedly connected to the top of the rotating tube 10.

[0020] Therefore, the specific implementation of this embodiment is: When the exhaust gas enters the cylinder 1 through the air inlet pipe 3, it will also blow the rotating impeller 9 to rotate, and then the rotating impeller 9 will drive the supporting filter plate 2 62 to rotate through the rotating tube 10, so that the supporting filter plate 2 62 and the supporting filter plate 1 61 rotate relative to each other, changing the distribution of the inner fillers of the supporting filter plates 1 61 and 2 62, disrupting the original flow path of the exhaust gas, making the flow of the exhaust gas in the cylinder 1 more complicated and disordered, thereby increasing the chance and area of ​​contact between the exhaust gas and the spray liquid, thereby improving the exhaust gas treatment effect. Embodiment 2

[0021] This embodiment adds a dust removal and dispersion mechanism 5 on the basis of the first embodiment, so as to remove part of the particulate matter in the exhaust gas in advance, reduce the deposition and scaling of the filler surface in the supporting filter plate 1 61 and the supporting filter plate 2 62, keep the pores and channels of the filler unobstructed, and also reduce the probability of the shower head and the pipeline being blocked. Figure 2 , Figure 4 and Figure 5 As shown, a dust removal and dispersion mechanism 5 for pretreatment is provided in the middle of the inner cavity of the cylinder 1, and the dust removal and dispersion mechanism 5 is sleeved on the outer side of the rotating tube 10 and is rotatably connected with the rotating tube 10. A collecting box 2 for collecting solid impurities inside the dust removal and dispersion mechanism 5 is provided in the middle and lower part of the outer surface of the cylinder 1. The horizontal height of the bottom of the communication port between the collecting box 2 and the fixed box 51 is greater than the horizontal height of the top of the discharge trough 54, so as to prevent the slurry in the fixed box 51 from flowing into the collecting box 2 autonomously, thereby affecting the collection of solid impurities by the collecting box 2. Specifically, Figure 4 and Figure 5 As shown, the dust removal and dispersion mechanism 5 includes a fixed box 51 fixedly connected to the mounting cylinder 4, and the fixed box 51 is connected to the inner cavity of the mounting cylinder 4. The top wall of the fixed box 51 is a filter plate structure. Looking from top to bottom, a plurality of filter holes on the top wall of the fixed box 51 are evenly distributed on the outside of the connection port between the bottom wall of the fixed box 51 and the mounting cylinder 4 to prevent the slurry after neutralization of the exhaust gas from entering the mounting cylinder 4. The left and right parts of the bottom wall of the fixed box 51 are provided with a discharge trough 54 vertically penetrating the side wall of the fixed box 51. The inner top of the discharge trough 54 is provided with a filter screen to filter solid impurities in the slurry and reduce the probability of clogging of the environmental protection water tank at the bottom of the cylinder 1. As can be seen from the above, the exhaust gas in the installation cylinder 4 first passes through the filter plate structure on the top wall of the fixed box 51 and flows out in a dispersed manner to avoid different exhaust gas concentrations in some areas. The slurry produced by the droplets sprayed by the atomizing nozzle assembly 7 after neutralizing the exhaust gas will also flow into the fixed box 51, increasing the moisture concentration in the fixed box 51, thereby increasing the capture of exhaust gas particles, reducing the deposition and scaling on the surface of the filler in the supporting filter plate 1 61 and the supporting filter plate 2 62, keeping the pores and channels of the filler unobstructed, and in addition, reducing the probability of blockage of the spray head and the pipeline, and the slurry finally leaves through the discharge trough 54.

[0022] Further, such as Figure 5 As shown, the top wall and the bottom wall of the fixed box 51 are both truncated cone structures that are close to each other in the middle. The horizontal filter plate structure may cause differences in the airflow through different areas of the filter plate due to the uneven initial distribution of the exhaust gas, affecting the uniformity of dispersion. The truncated cone filter plate structure will cause the exhaust gas to flow along the inclined surface, thereby generating different resistances and flow direction changes at different positions, which will help to better adjust and mix the airflow, making the final dispersion effect more uniform.

[0023] In order to avoid excessive solid impurities in the fixed box 51, which may affect the effect of the fixed box 51 in dispersing exhaust and filtering slurry, specifically, Figure 6 and Figure 7 As shown, in this embodiment, a collecting mechanism 53 for cleaning solid impurities is provided on a portion of the outer surface of the rotating tube 10 located on the inner side of the fixed box 51. The collecting mechanism 53 includes a movable box 531 fixedly connected to the rotating tube 10, and the movable box 531 and the inner cavity bottom wall of the fixed box 51 are in close contact with each other to better collect the solid impurities remaining on the bottom wall of the fixed box 51 and the filter screen. The upper end of the movable box 531 is an inclined surface structure for facilitating the sliding of the slurry. An opening groove 538 is provided on a portion of the rear side wall of the movable box 531 away from the rotating tube 10 to facilitate the movable box 531 to collect the solid impurities remaining on the bottom wall of the fixed box 51 and the filter screen when rotating. A portion of the inner cavity bottom wall of the movable box 531 away from the rotating tube 10 is provided with a triangular grinding block 535 for serving as a temporary closing component. The triangular grinding block 535 cooperates with the U-shaped plate 536 to facilitate the movement of the U-shaped plate 536 to move the movable box 531. The solid impurities collected in the moving box 531 are pushed into the collecting box 2. The front inner wall and the rear inner wall of the triangular grinding block 535 are both provided with inclined parallelogram grooves 534. The inclined parts of the left and right parts of the inclined parallelogram groove 534 have the same inclination angle as the inclined surface of the left end of the triangular grinding block 535. A bidirectional screw 533 is horizontally provided on the upper part of the inner wall of the side of the moving box 531 close to the rotating tube 10. The outer surface of the bidirectional screw 533 is provided with a telescopic plate 532. The bottom of the end of the telescopic plate 532 away from the rotating tube 10 is provided with a U-shaped plate 536 for collecting solid impurities, and the lower horizontal part of the U-shaped plate 536 is an inclined structure adapted to the bottom wall of the moving box 531. The upper front end and the upper rear end of the U-shaped plate 536 are both provided with elastic telescopic rods 537, and the two elastic telescopic rods 537 are respectively slidably connected to the inclined parallelogram groove 534 on the same side; Specifically, a fixing rod 17 is provided in the middle of the bottom wall of the installation cylinder 14, and the fixing rod 17 is located inside the rotating tube 10, and one end of the bidirectional screw 533 close to the rotating tube 10 extends to the inside of the rotating tube 10 and a bevel gear set 18 is provided between the upper end of the fixing rod 17; Further, when the U-shaped plate 536 moves to the farthest distance from the rotating tube 10, the middle of the connecting opening of the movable box 531 and the collecting box 2 and the fixed box 51 are located in the same vertical plane, and the movable box 531 is connected to the collecting box 2, that is, the movable box 531 is located at Figure 6 The symmetrical position of the middle moving box 531; In addition, since the bottom wall of the fixed box 51 is a truncated cone structure with a high middle and low sides, most of the liquid in the fixed box 51 will leave through the discharge groove 54, leaving only a small amount of liquid and most of the solid impurities; As can be seen from the above, when the rotating tube 10 controls the mobile box 531 to rotate and collects the solid impurities in the fixed box 51 through the open groove 538, it will also control the bidirectional screw 533 to rotate through the bevel gear set 18, and then the bidirectional screw 533 controls the telescopic plate 532 to move horizontally. In this process, the U-shaped plate 536 will also drive the telescopic plate 532 to stretch under the action of the elastic telescopic rod 537 and the inclined parallelogram groove 534, so that the U-shaped plate 536 can move in an inclined direction to collect the solid impurities in the mobile box 531. Finally, the U-shaped plate 536 moves upward under the action of the inclined part of the right side of the inclined parallelogram groove 534 and the triangular grinding block 535, and the collected solid impurities are put into the collecting box 2 through the connecting port between the fixed box 51 and the collecting box 2, thereby reducing the residual solid impurities in the fixed box 51 and avoiding clogging the filter screen and affecting the departure of the slurry.

[0024] Since the slurry enters the inner side of the fixed box 51 through the filter holes on the top wall of the fixed box 51, the inner wall of the filter holes is relatively moist, which makes it very easy to capture particulate matter in the exhaust gas, thereby changing the aperture of the filter holes. In addition, when the liquid passes through the filter holes, due to the uneven flow rate and pressure distribution, there is more time and opportunity to form a liquid film at the upper and lower openings of the filter holes on the top wall of the fixed box 51. In summary, these will affect the effect of dispersing the exhaust gas by the fixed box 51, resulting in different local concentrations when the device treats the exhaust gas, which affects the exhaust gas treatment effect to a certain extent. Specifically, Figure 4 , Figure 8 and Fig. 9As shown, in this embodiment, a movable mechanism 52 for clearing the filter holes on the top wall of the fixed box 51 is provided in the middle and upper part of the inner cavity of the fixed box 51, and the movable mechanism 52 includes a plurality of sliding rods 522, and the plurality of sliding rods 522 respectively correspond to the positions of the filter holes on the top wall of the fixed box 51, and the top and bottom of the sliding rods 522 are both hemispherical structures that are convenient for movement under pressure, and a fixed frame 521 is commonly provided at the lower part of the outer surface of the plurality of sliding rods 522, and the fixed frame 521 is fixedly connected to the inner wall of the fixed box 51, and the fixed frame 521 is slidably connected to the sliding rods 522, and the upper part of the sliding rods 522 extends into the filter holes on the top wall of the fixed box 51 and is provided with six connecting rods 524, and the six connecting rods 524 are commonly provided with a movable tube 523 for cleaning the filter holes at one end away from the sliding rods 522, and the top wall and the bottom wall of the movable tube 523 are both inclined surface structures that facilitate the sliding of slurry; It can be seen from this that when the moving box 531 rotates, it will also use the inclined surface structure on its top to push part of the sliding rod 522, and then use the self-gravity of the sliding rod 522 and the moving tube 523 to force the sliding rod 522 and the moving tube 523 to move up and down, scraping off the solid impurities attached to the inner wall of the filter hole, and using the falling impurities and the movement of the sliding rod 522 and the moving tube 523 to destroy the liquid film that may be produced at the upper and lower openings of the filter hole, and some impurities attached to the inner wall of the moving tube 523 will fall off most of them under the impact of the impurities scraped off the inner wall of the filter hole and the inertia during the up and down movement, thereby minimizing the impact of the moving tube 523 on the exhaust gas circulation.

[0025] Furthermore, the farther the plurality of movable tubes 523 are from the rotating tube 10 , the shorter the length of the movable tubes 523 is, so that the movable tubes 523 at various locations move downward and extend out of the filter holes by the same distance, so that the exhaust gas can be dispersed as evenly as possible.

[0026] Further, such as Figure 5 and Figure 6 As shown, a trapezoidal scraper 8 is provided on the upper portion of the outer surface of the rotating tube 10 for pushing the slurry on the upper end of the fixed box 51, and the upper side of the inclined surface at the bottom of the trapezoidal scraper 8 is at the same level as the horizontal plane where the top of the sliding rod 522 is located after the maximum upward movement, so that the sliding rod 522 can destroy the liquid film that may exist at the top opening of the filter hole when moving upward; In addition, after the device has been used for a long time, the sliding rod 522 may increase its own friction coefficient due to corrosion and other problems, making it impossible for the sliding rod 522 to slide naturally. This allows the trapezoidal scraper 8 to not only push the slurry to the filter hole, but also push down the sliding rod 522 that fails to fall in time, so that the dust removal and dispersion mechanism 5 can continue to function, reduce the maintenance of the device, and thus improve the practicality of the device.

[0027] Furthermore, the moving tube 523 is always located at the lower side of the upper end surface of the fixed box 51 to avoid hindering the movement of the trapezoidal scraper 8.

[0028] Therefore, the specific implementation of this embodiment is: The exhaust gas in the installation cylinder 4 first passes through the filter plate structure on the top wall of the fixed box 51 and flows out evenly and dispersedly to avoid different exhaust gas concentrations in some areas. The slurry produced by the droplets sprayed by the atomizing nozzle assembly 7 after neutralizing the exhaust gas will first drip onto the fixed box 51, and then, under the push of the trapezoidal scraper 8, enter the inner side of the fixed box 51 through the filter holes on the top wall of the fixed box 51, and then pass through the discharge trough 54 and the filter screen for solid-liquid separation; During this process, the rotating tube 10 will control the mobile box 531 to rotate and collect the solid impurities remaining in the fixed box 51, and control the bidirectional screw 533 to rotate through the bevel gear set 18. Then, under the action of the elastic telescopic rod 537 and the inclined parallelogram groove 534, the U-shaped plate 536 moves in an inclined direction to collect the solid impurities in the mobile box 531. Then, under the action of the right inclined part of the inclined parallelogram groove 534 and the triangular grinding block 535, the U-shaped plate 536 moves upward, and the collected solid impurities are put into the collecting box 2 through the connecting port between the fixed box 51 and the collecting box 2, thereby reducing the residual solid impurities in the fixed box 51, avoiding clogging of the filter screen, and affecting the departure of the slurry. In addition, during the rotation process, the moving box 531 will also use the inclined surface structure on its top to push part of the sliding rod 522, and then use the self-gravity of the sliding rod 522 and the moving tube 523 to force the sliding rod 522 and the moving tube 523 to move up and down, scraping off the solid impurities attached to the inner wall of the filter hole, and using the falling of impurities and the movement of the sliding rod 522 and the moving tube 523 to destroy the liquid film that may be produced at the upper and lower openings of the filter hole, so as to avoid affecting the emission of exhaust gas.

[0029] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention.
