[0002] A related technology (announcement number: CN222076241U) discloses a spray device for treating organic waste gas, including a working box. Connecting cylinders are fixedly connected to both ends of the working box. A suction pump is fixedly installed on the surface of each connecting cylinder. A first filter plate is fixedly installed on one side of the inner wall of the connecting cylinder. A second filter plate is fixedly installed inside the working box. A water pump is fixedly installed on one side of the top of the working box. A water pipe is provided at the output end of the water pump. A water tank is fixedly connected to one end of the water pipe, and a spray nozzle is fixedly connected to the other end of the water pipe. An electric three-way valve is fixedly installed on the surface of the water pipe.

[0003] In the process of implementing the technical solution disclosed herein, at least the following problems were found in the related technologies:

[0004] This spray device for treating organic waste gas draws the organic waste gas from the connecting cylinder into the working chamber. A water pump and an electric three-way valve then extract water from the water tank or working chamber and spray it into the working chamber through nozzles to filter the organic waste gas. However, because the spray liquid directly contacts the organic waste gas, sufficient contact between the two is difficult, resulting in poor treatment efficiency.

[0018] This disclosure provides a spraying device for treating organic waste gas, comprising a spray tower, a shell, hollow shafts, branch pipes, nozzles, a first pipe, a second pipe, and a grid plate. The spray tower includes multiple through holes evenly distributed along its height on its sidewalls, each through hole allowing passage of relevant components of the device. The shell is installed on the inner wall of the spray tower and surrounds the multiple through holes, supporting the relevant components and providing sealing protection. Hollow shafts are rotatably inserted through the bottom wall of each shell along the height of the spray tower. The axes of the hollow shafts coincide with the axis of the spray tower, allowing them to rotate relative to the tower's axis and transport spray liquid. Branch pipes are installed at the bottom ends of the hollow shafts and connected to them. Both ends of the branch pipes are sealed, serving to contain spray liquid and support the nozzles.

[0037] Combination Figures 1 to 5As shown in the figure, this disclosure provides a spraying device for treating organic waste gas, including a spraying tower 1, a shell 2, hollow shafts 3, branch pipes 4, nozzles 5, a first pipe 6, a second pipe 7, and a grid plate 8. The spraying tower 1 includes multiple through holes located on its sidewalls and evenly distributed along its height direction, each through hole being used for the passage of relevant components of the device. The shell 2 is installed on the inner wall of the spraying tower and surrounds the multiple through holes, supporting the relevant components of the device and providing sealing protection. The hollow shafts 3 are rotatably inserted through the bottom wall of each shell 2 along the height direction of the spraying tower 1. The axes of the multiple hollow shafts 3 coincide with the axis of the spraying tower 1, allowing them to rotate relative to the axis of the spraying tower 1 and transport spray liquid. The branch pipes 4 are installed at the bottom ends of the multiple hollow shafts 3 and are connected to the bottom ends of the multiple hollow shafts 3. Both ends of the multiple branch pipes 4 are sealed, serving to contain spray liquid and support the nozzles 5. Nozzles 5 are evenly installed on each branch pipe 4, and each branch pipe 4 is connected to multiple nozzles 5 thereon, all for spraying spray liquid. First pipes 6 are located inside multiple shells 2, one end of each first pipe 6 is rotatably connected to the top of multiple hollow shafts 3, and the other end of each first pipe 6 passes through multiple through holes, all for conveying spray liquid. Second pipes 7 are connected to the ends of the first pipes 6 located outside the multiple shells 2, one end of the second pipe 7 is sealed, and the other end is used to connect to a liquid supply device and also for conveying spray liquid. Grid plates 8 are installed on the inner wall of the spray tower 1, along the height direction of the spray tower 1, below each of the multiple shells 2, for supporting the packing material. Multiple hollow shafts 3 are controlled to rotate simultaneously, thereby driving multiple branch pipes 4 to rotate simultaneously.

[0038] This disclosure provides a spray device for treating organic waste gas. By controlling the operation of the liquid supply equipment, the spray liquid enters the hollow shaft 3 through the second pipe 7 and multiple first pipes 6, then enters the multiple branch pipes 4, and is finally sprayed out by multiple nozzles 5 on each branch pipe 4. Driven by an external force, the multiple hollow shafts 3 rotate simultaneously, which in turn drives the multiple branch pipes 4 to rotate. This, in turn, drives the multiple nozzles 5 on each branch pipe 4 to rotate, thereby uniformly spraying the spray liquid onto the packing layers on multiple grid plates, forming a uniform liquid film. The organic waste gas then enters through the inlet of the spray tower 1 and, as it passes through multiple grid plates, fully contacts the liquid film through multiple packing layers, achieving mass transfer and chemical reaction between the gas and liquid phases. This allows for a thorough chemical reaction, and the gas is finally discharged from the outlet of the spray tower 1, improving the treatment effect.

[0039] Optionally, combined Figures 1 to 4As shown, the system also includes driven synchronous pulleys 9, support plates 10, rotating shafts 11, driving synchronous pulleys 12, and synchronous toothed belts. The driven synchronous pulleys 9 are respectively mounted on the outer walls of multiple hollow shafts 3 and located inside multiple housings 2, respectively, and are used to drive the multiple hollow shafts 3 to rotate. The support plate 10 is connected to the outer wall of the spray tower 1 and is used to support and mount the rotatable rotating shaft 11. The rotating shaft 11 is rotatably mounted on the support plate 10 along the height direction of the spray tower 1 and is opposite to multiple through holes, allowing it to rotate relative to the support plate 10. The driving synchronous pulleys 12 are mounted on the rotating shaft 11 and are respectively opposite to the multiple driven synchronous pulleys 9, all rotating under the drive of the rotating shaft 11. Along the height direction of the spray tower 1, the diameter of the multiple driving synchronous pulleys 12 increases sequentially from top to bottom. The synchronous toothed belts are respectively fitted between the opposite driving synchronous pulleys 12 and driven synchronous pulleys 9, respectively, and are used to transmit driving force. The rotating shaft 11 can be rotated in a controlled manner so that multiple hollow shafts 3 can rotate simultaneously.

[0040] In this embodiment, the rotating shaft 11 rotates under external force, which in turn drives multiple active synchronous pulleys 12 to rotate. Through multiple synchronous toothed belts, multiple hollow shafts 3 can be driven to rotate, ultimately achieving the function of rotating multiple nozzles 5 on each branch pipe 4. Compared to driving multiple hollow shafts 3 separately, this reduces the number of power sources. Furthermore, the design of the diameter of the multiple active synchronous pulleys 12 increasing sequentially from top to bottom allows the rotational speed of the multiple hollow shafts 3 to increase sequentially from top to bottom. This results in a more uniform liquid film thickness at the bottom, improving the treatment effect on flue gas with a high organic waste gas content at the bottom of the tower.

[0041] Optionally, combined Figure 1 , Figure 2 and Figure 5 As shown, it also includes a support rod 13, a mounting plate 14, a motor 15, and a coupling. The support rod 13 is installed on the top surface of the support plate 10 along the height direction of the spray tower 1, supporting the mounting plate 14. The mounting plate 14 is installed at the top of the support rod 13, supporting the motor 15. The motor 15 is installed on the top surface of the mounting plate 14, with its rotating end passing through the mounting plate 14 to provide driving force. The coupling is installed between the rotating end of the motor 15 and the rotating shaft 11 to transmit driving force.

[0042] In this embodiment, the control motor 15 operates, and through a coupling, it drives the rotating shaft 11 to rotate, ultimately achieving the function of automatic rotation of multiple nozzles 5 on each branch pipe 4.

[0043] Optionally, combined Figure 1 , Figure 2 and Figure 5As shown, it also includes a first bearing housing 16 and a first bearing. The first bearing housing 16 is mounted on the support plate 10 and sleeved on the rotating shaft 11. The first bearing is installed between the first bearing housing 16 and the rotating shaft 11.

[0044] In this embodiment, after the first bearing housing 16 is installed on the support plate 10, it is used to support and install the first bearing and limit the position of the first bearing. The first bearing is used to support and install the rotatable rotating shaft 11, reduce the frictional force on the rotating shaft 11, and improve the rotational accuracy of the rotating shaft 11.

[0045] Optionally, combined Figure 1 , Figure 4 and Figure 5 As shown, it also includes a seated bearing 17. The seated bearing 17 is fitted onto the rotating shaft 11, installed on the outer wall of the spray tower 1, and is evenly distributed along the height direction of the spray tower 1. Each of the multiple seated bearings 17 includes a notch, and the second pipe 7 passes through the multiple notches.

[0046] In this embodiment, the mounted bearing 17 is used to reduce the radial runout of the rotating shaft 11, thereby ensuring the stability of the rotating shaft 11 during rotation. Furthermore, the notches of the plurality of mounted bearings 17 can be used for passage of the second conduit 7, so that the second conduit 7 can be connected to the plurality of first conduits 6.

[0047] Optionally, combined Figure 1 and Figure 5 As shown, it also includes a material exchange port 18 and a sealing cover.

The sealing cover is detachably installed on multiple material exchange ports 18, and is used to open or close multiple material exchange ports 18 respectively.

[0048] In this embodiment of the disclosure, when the multiple sealing covers open the multiple material replacement ports 18, the packing material on the multiple grid plates can be replaced. When the multiple sealing covers close the multiple material replacement ports 18, the packing material and spray liquid can be prevented from flowing out of the multiple material replacement ports 18.

[0049] Optionally, combined Figure 1 and Figure 3 As shown, it also includes a second bearing housing 19 and a second bearing. The second bearing housing 19 is respectively mounted on multiple housings 2 and respectively sleeved on multiple hollow shafts 3. The second bearing is respectively installed between multiple second bearing housings 19 and multiple hollow shafts 3.

[0050] In this embodiment, the second bearing housing 19 is installed on multiple housings 2 to support and limit the installation of multiple second bearings. The multiple second bearings are used to support and install multiple rotatable hollow shafts 3, reducing the frictional force on the multiple hollow shafts 3 and improving the rotational accuracy of the multiple hollow shafts 3.

[0051] Optionally, combined Figures 1 to 4 As shown, it also includes supports 20. Supports 20 are respectively fitted onto multiple first pipes 6 and respectively installed on the inner walls of multiple housings 2.
