DETAILED DESCRIPTION

[0024] Clearly, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0025] Please refer to Figures 1-5 The utility model provides a technical scheme: a kind of high-efficiency liquid distributor suitable for triethylene glycol absorption tower, and the bottom of installation cylinder 1 is provided with discharge plate 2, and a plurality of groups of liquid outlet holes 201 are opened in discharge plate 2.

[0026] Specifically, the liquid outlet hole 201 is provided below with a drainage mechanism 202 used in cooperation with the liquid outlet hole 201, the drainage mechanism 202 comprises a tapered drainage frame 2021, and a drainage pipe 2022 is installed at the end of the tapered drainage frame 2021 away from the liquid outlet hole 201, liquid flows down from the tapered drainage frame 2021, collects at the tip of the tapered drainage frame 2021, and the drainage pipe 2022 at the tip can drain the liquid into the reaction container. A circular adjusting plate 3 is rotatably arranged on the top of the discharge plate 2, and a plurality of groups of adjusting holes 301 used in cooperation with the liquid outlet hole 201 are arranged on the circular adjusting plate 3. A drive rod 302 is installed at the center of the top of the circular adjusting plate 3, and a first bevel gear 303 is arranged on the outer side of the drive rod 302. The first bevel gear 303 is engaged with a second bevel gear 304, and the second bevel gear 304 is installed on the outer side of a rotating rod 305. One end of the rotating rod 305 is connected with a speed reduction drive mechanism 306. The speed reduction drive mechanism 306 comprises a drive motor 3061, and the drive motor 3061 can drive a first gear 3063 arranged inside a mounting box 3062 to rotate. The first gear 3063 is engaged with a second gear 3064, and the second gear 3064 is installed on the outer side of a rotating rod 3065. A third gear 3066 is arranged on the outer side of the rotating rod 3065, and the third gear 3066 is engaged with a fourth gear 3067. The fourth gear 3067 is installed on the outer side of the rotating rod 305. The size of the second gear 3064 is greater than that of the first gear 3063, and the size of the fourth gear 3067 is greater than that of the third gear 3066. When it is necessary to adjust the liquid flow rate of the liquid outlet hole 201, the drive motor 3061 is started. Under the action of the drive motor 3061, the first gear 3063 arranged inside the mounting box 3062 can be driven to rotate. Since the first gear 3063 is engaged with the second gear 3064 and the size of the first gear 3063 is smaller than that of the second gear 3064, the second gear 3064 can be driven to rotate at a reduced speed. The second gear 3064 drives the rotating rod 3065 and the third gear 3066 to rotate synchronously. Since the third gear 3066 is engaged with the fourth gear 3067 and the size of the third gear 3066 is smaller than that of the fourth gear 3067, the fourth gear 3067 and the rotating rod 305 can be driven to rotate at a reduced speed. The rotating rod 305 drives the first bevel gear 303 and the drive rod 302 to rotate through the second bevel gear 304. Thus, the circular adjusting plate 3 is driven to rotate through the drive rod 302, so that the adjusting holes 301 move, the overlapping area of the adjusting holes 301 and the liquid outlet hole 201 changes, liquid flows out from the overlapping area, and thus the liquid flow rate changes. The arrangement of the speed reduction drive mechanism 306 can slow down the movement speed of the adjusting holes 301, thereby facilitating later adjustment.

[0027] In further embodiments, a liquid storage tank 4 is arranged inside the mounting cylinder 1 and above the circular adjusting plate 3. A plurality of liquid outlets 401 are arranged on the bottom of the liquid storage tank 4, and liquid valves matched with the liquid outlets 401 are installed in the liquid outlets 401. Liquid is first stored in the liquid storage tank 4, thereby avoiding the liquid from gathering in one place when entering.

[0028] In still further embodiments, the circular adjusting plate 3 is symmetrically provided with a stabilizing rod 5 at the top, and the stabilizing rod 5 is provided with a sliding block 501 at one side of the top, and the sliding block 501 is in sliding connection with a ring-shaped sliding groove 601 arranged inside the triethylene glycol absorption tower 6, so that the stability of the circular adjusting plate 3 during rotation can be improved.

[0029] The terms "center", "longitudinal", "transverse", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, which is only a simplified description for the convenience of describing the utility model, and does not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the protection scope of the utility model.
