In order to further improve the working stability of the combined packing absorption tower, the upper end and the lower end of the regular packing part 3 are provided with the supporting grid plates 4. The support grid 4 comprises an abutment ring body 41, an elastic connection column 42 and a bearing ring body 43 which are connected in sequence. Wherein a height difference is formed between the abutment ring body 41 and the bearing ring body 43. The bearing ring body 43 is connected with the rotation of drive slewing mechanism, and the butt ring body 41 is used for the corresponding one end butt with regular packing portion 3, and the elastic connection post 42 is used for connecting butt ring body 41 and bearing ring body 43. Therefore, support grid plate 4 and play the effect of effective restriction regular packing portion 3 position, wherein be connected corresponding high position through bearing ring body 43 and drive slewing mechanism's rotation to elastic connection post 42 drive butt ring body 41 and regular packing portion 3 butt make this combination formula packing absorption tower have simple structure, simple operation and stable effect. Meanwhile, the driving rotation mechanism comprises a driving motor 2 and two driving rotary columns 5 which are respectively connected with the corresponding structured packing parts 3. The axis of the driving rotary column 5 coincides with the axis of the tower 1. Be provided with a plurality of fixed connecting rod 51 that match fixedly respectively with corresponding initiative packing layer 31 on drive rotary column 5, two drive rotary column 5 interconnect, and driving motor 2 is used for drive rotary column 5 to be the circumferential direction rotary motion, and then when driving motor 2 drives drive rotary column 5 and is the circumferential direction rotary motion, fixed connecting rod 51 rotates and drives and match fixed initiative packing layer 31 and rotate to realize the regular packing layer of steady drive and rotate and realize the purpose of stable gas-liquid contact.

As shown in fig. 6, 7 and 8, the bottom of the driving rotary column 5 at the upper end is provided with a plurality of connecting ridges 52 distributed in an equal arc. A gap for liquid flowing is formed between two adjacent connecting ridges 52, and the bottom of the connecting ridge 52 is connected with the central connecting column 71 of the corresponding rotary liquid outlet device 7. The top of the driving rotary column 5 at the lower end is fixedly connected with a corresponding rotary liquid outlet 7. Therefore, the connecting prism 52 is connected with two coaxial driving rotation, and simultaneously, the liquid collected by the liquid redistributor 8 passes through and enters the rotating liquid outlet device 7 at the lower end, and the effects of simple connecting structure, high structural stability and low production cost are achieved.

It should be mentioned that the drive motor 2 is provided with a drive connection rod 21. The driving connecting rod 21 is arranged along the transverse direction and is connected with a driving helical tooth 22. The bottom of the drive turret 5 at the lower end is provided with turret helical teeth 54 which mesh with the drive helical teeth 22, and a drive gear 53. The rotary column helical teeth 54, the driving gear 53 and the driving rotary column 5 are coaxially arranged and do circumferential rotation motion with the same angular velocity. A U-shaped ring groove 15 communicating with the air inlet pipe 12 is provided inside the lower end of the tower body 1. The gas distributor 9 is plugged into the U-shaped ring groove 15. The gas outlet 92 is located inside the gas distributor 9 and has a circular arc outer sidewall. The driving gear 53 is meshed with a driven gear 94, the driven gear 94 is fixedly connected with a rotary driving part 93, a plurality of grooves matched with the air outlet part 92 are formed in the peripheral side wall of the rotary driving part 93, an air inlet ring groove 91 used for being communicated with the air inlet pipeline 12 is formed in one side, away from the axis, of the air distributor 9, and therefore when the driving motor 2 runs, the driving connecting rod 21 drives the driving helical teeth 22 to rotate circumferentially, so that the rotary column helical teeth 54 meshed with the driving helical teeth 22 rotate, and the rotary column helical teeth 54 and the driving rotary column 5 are coaxially fixed, so that when the rotary column helical teeth 54 rotate, the driving rotary column 5 rotates in the same circumferential direction as the rotary column helical teeth 54; when the driving rotary column 5 rotates, the driving gear 53 which is coaxial is driven to rotate, and the driven gear 94 is meshed with the driving gear 53, so that the driven gear 94 performs circumferential rotation motion opposite to that of the driving gear 53, and the gas distributor 9 is driven to perform circumferential rotation motion opposite to that of the structured packing part 3 and the liquid distributor; wherein, the gas inlet ring groove 91 keeps real-time intercommunication with air inlet pipeline 12 for gas distributor 9 to when making gas get into in the tower body 1 through air inlet pipeline 12, go out gas portion 92 to the upper end of tower body 1 exhaust on the gas distributor 9 in the U type ring groove 15 again, thereby realize showing the availability factor who promotes this combination formula filler absorption tower.

To sum up, when the driving rotating column 5 is driven to do circumferential rotation motion by the driving motor 2, the driving gear 53 rotates and drives the driven gear 94 to do reverse rotation motion, at this time, the gas distributor 9 does clockwise or counterclockwise circumferential rotation under the drive of the driven gear 94, the structured packing portion 3 and the rotating liquid outlet device 7 do counterclockwise or clockwise circumferential rotation under the drive of the driving rotating column 5, the rotational angular velocity of the driving packing layer 31 in the structured packing portion 3 is the same as the rotational angular velocity of the driving rotating column 5, and the rotational angular velocity of the driving packing layer 32 is smaller than or equal to the rotational angular velocity of the driving rotating column 5, so as to realize that gas and liquid do opposite rotation motion, thereby realizing the obvious improvement of gas-liquid contact effect in the tower body 1 of unit height and obviously improving the use efficiency of the combined packing absorption tower.
