The following is a detailed description of various embodiments of the present utility model in conjunction with the drawings.

[0024] Example 1

[0025] See also Figures 1 to 8The utility model preferably provides a technical solution: a sewage odor treatment spray tower, comprising: a tower body 101, and a plurality of filler absorption components 6 and spray components 7, the plurality of filler absorption components 6 and spray components 7 are arranged alternately on the tower body 101 from bottom to top and are connected with the tower body 101; the side wall of the tower body 101 near its bottom and the top thereof are respectively provided with an air inlet 2 and an exhaust port 3, when the exhaust gas flows through the plurality of filler absorption components 6 and the spray components 7 from bottom to top, the air inlet 2 and the exhaust port 3 are respectively used for the exhaust gas to enter and the purified gas to be discharged; each group of filler absorption components 6 includes a shell 102, and a cover body 103 arranged on the top of the shell 102, and also includes a cover body 103 rotatably connected to the middle of the shell 102 The frame 608 has three filling components installed on the outer end of the frame 608, and the positions of the three filling components can be transferred. The shell 102 and the cover 103 are respectively provided with a first through slot and a second through slot, and the first through slot is used for connecting the filling component with the tower body 101. The frame 608 also includes a recoil component vertically arranged on a plurality of filling absorption components 6 and connected with the components through the second through slot. The frame 608 also includes a replacement component 8 arranged on the upper surface of each cover 103, which is used for purifying the exhaust gas when the filling component is moved to the tower body 101 and placed under the corresponding spray component 7. When the filling component is docked with the recoil component, it is used for backwashing the filling component. When the filling component is moved to the position of the replacement component 8, it is used for the replacement operation of the filling component.

[0026] In this application, if Figure 1 , 2 As shown in Figures 3 and 4, a plurality of filler absorption components 6 and spray components 7 are alternately arranged on the tower body 101 from bottom to top and are connected to the tower body 101, and cooperate with the air inlet 2 and the exhaust port 3 arranged on the bottom and top side walls of the tower body 101 to realize that the exhaust gas enters the interior of the tower body 101 through the air inlet 2, and flows through the plurality of filler absorption components 6 and the spray components 7 from bottom to top to realize the exhaust gas purification process, and then through the design of the exhaust port 3, the exhaust process of the purified gas is further realized;

[0027] like Figure 5 , 6 As shown, each filler absorption assembly 6 includes a shell 102, a cover 103, and a frame 608 provided in the shell 102, and three filler components provided at the outer end of the frame 608. Here, the frame 608 is rotatably connected to the shell 102, and is fixedly connected to the three filler components. Therefore, by rotating the frame 608, the position switching process of the three filler components is realized. This design uses the position switching characteristics of the three filler components to cooperate with the recoil components provided on several filler absorption assemblies 6, and the replacement assembly 8 provided on each cover 103. It is worth noting that the first through groove and the second through groove provided on the shell 102 and the cover 103 are used for the connection between the filler component and the tower body 101 and the recoil component.

[0028] When the packing component is driven to move to the first through groove and docked with the tower body 101 and placed directly below the corresponding spray assembly 7, the packing component participates in the purification process of the exhaust gas;

[0029] When the packing component is driven to move to the second through groove and dock with the backflushing assembly, the backflushing operation of the packing component is realized;

[0030] When the packing component moves to the position of the replacement component 8, it is further used for the replacement operation of the packing component;

[0031] Therefore, the utility model realizes the purification, backwashing and replacement process of the packing components by adjusting the positions of the three packing components.

[0034] It is worth noting that: when the gas enters the tower body 101 through the air inlet 2, and then flows from bottom to top through the packing layer 605 where the packing absorption component 6 is located, when the exhaust gas contacts the surface of the packing layer 605, the dirt in the gas can react with the chemical substances in the liquid on the surface of the packing, and the soluble substances generated by the reaction can flow with the absorption liquid to the water outlet trough arranged below the tower body 101, that is, the wastewater chamber 504 where the water storage tank component 5 is located below, and the liquid that is not completely absorbed continues to rise to the spray component 7 to further complete the purification process.

[0036] like Figure 5 , 6 As shown in Figure 8, the transmission rod 602 is fixedly connected to the frame 608 where the several filling absorption components 6 are located, and the frame 608 is rotatably connected to the shell 102. Therefore, when the motor 603 is driven to realize the rotation of the transmission rod 602, the synchronous rotation of the several frames 608 is realized, and the synchronous position switching of the filling components where the several filling absorption components 6 are located is further realized.

[0037] Furthermore, each set of replacement components 8 includes a threaded groove opened on the cover body 103, and a threaded cover arranged inside the threaded groove; and also includes a handle fixed on the top of the threaded cover.

[0038] like Figure 1 , 8 As shown, when a filler component needs to be replaced, the corresponding filler component is driven to be placed in the thread groove where the cover body 103 is located, and then the threaded cover is operated to realize the replacement operation of the filler component.

[0039] Furthermore, each group of spray assemblies 7 includes a mounting ring 701, which is arranged on the inner wall of the tower body 101, and a spray rack 702 fixed inside the mounting ring 701 and connected thereto, and the spray rack 702 is placed above the corresponding filler component; it also includes a return pipe assembly arranged on the side wall of the tower body 101, and the return pipe assembly is used for supplying water to the mounting ring 701.
