Description

Technical Field

[0001] This utility model relates to the field of reflux tank technology for catalytic distillation towers, specifically a discharge device for a reflux tank of a catalytic distillation tower. Background Technology

[0002] The main functions of a reflux tank in a catalytic distillation column include improving separation efficiency, stabilizing operation, and preventing overheating. The working principle of the reflux tank is based on the difference in volatility of substances at different temperatures. By heating, the volatile components in the mixture are vaporized, and then condensed and collected. The condensed liquid portion is pumped back into the top of the distillation column as reflux liquid to increase the gas-liquid contact area and time, thereby improving separation efficiency. The remaining liquid is collected as the product, completing the entire separation process. Existing methods typically use a three-way valve for diverting the flow, with two valves controlling the reflux and discharge rates. However, this control method is relatively simple, requiring separate adjustments, which is cumbersome and not suitable for one-time control. Therefore, a flow rate ratio adjustment orifice for quick reflux and discharge is designed for a more convenient and efficient reflux tank discharge device in a catalytic distillation column. Summary of the Invention

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0022] Please see Figure 1-5 A discharge device for a reflux tank of a catalytic distillation column includes a discharge tank 1 whose top can be connected to the discharge port of the reflux tank of the catalytic distillation column. The bottom of the discharge tank 1 is circumferentially connected to a discharge pipe 2 and a reflux pipe 3 respectively disposed on both sides. The bottom of the discharge tank 1 is rotatably connected to an adjusting cylinder 4 that is sealed and slidably fitted with the inner side wall of the discharge tank 1. The bottom of the adjusting cylinder 4 is circumferentially provided with a discharge port 5 that communicates with the discharge pipe 2 and the reflux pipe 3. When either the discharge pipe 2 or the reflux pipe 3 is fully connected to one of the discharge ports 5, the other discharge pipe 2 and the other reflux pipe 3 are not fully connected to the other discharge port 5. Furthermore, both discharge ports 5 can be simultaneously not connected to either the discharge pipe 2 or the reflux pipe 3. The bottom of the discharge tank 1 is provided with an adjusting mechanism for rotating and adjusting the adjusting cylinder 4 and a locking mechanism for fixing the adjusting cylinder 4.

[0023] Specifically, the adjustment mechanism includes a rotating sleeve 8 fixedly installed at the bottom center of the adjustment cylinder 4 and rotatably connected to the bottom of the discharge tank 1. A gear 12 is fixedly installed on the rotating sleeve 8, and a rack 13 is meshed on one side of the gear 12. The mechanism also includes a feeding moving component that drives the rack 13 to move. Through the feeding moving component, the guide block 15 can be easily moved, so that the guide block 15 meshes with the gear 12, thereby driving the rotating sleeve 8 and the adjustment cylinder 4 to rotate clockwise or counterclockwise as a whole.

[0024] Specifically, the feeding and moving assembly includes a drive cylinder 14 fixedly installed at the bottom of the discharge tank 1. The output shaft of the drive cylinder 14 is fixedly mounted with a moving frame sleeved on the outside of the gear 12. The rack 13 is fixedly installed on the moving frame. The bottom of the discharge tank 1 also includes a guide block 15 that slides with the moving frame. The guide block 15 facilitates the guiding and moving of the moving frame, and the drive cylinder 14 facilitates the overall feeding and moving of the moving frame and the guide block 15.

[0025] Specifically, the locking mechanism includes a fixed sleeve 10 fixedly installed at the bottom of the rotating sleeve 8. A locking rod that can be locked onto the fixed sleeve 10 is fixedly connected to the fixed sleeve 10 via a tension spring 11. A limiting gear 16 that can lock the gear 12 is fixedly installed on the locking rod. The tension spring 11 allows the limiting gear 16 to be positioned at the gear 12, thereby preventing the gear 12 from rotating. The cooperation between the locking rod and the fixed sleeve 10 improves the stability of the limiting gear 16 locking the gear 12. When it is necessary to release the lock, the locking rod can be pulled down to further stretch the tension spring 11 and release the limiting gear 16 from limiting the gear 12, so that the adjustment mechanism can continue to be adjusted.

[0026] Specifically, a flow guiding mechanism is provided at the bottom of the regulating cylinder 4. The flow guiding mechanism includes a rotating shaft 6 rotatably connected to the bottom of the regulating cylinder 4. A flow guiding screw ribbon 7 is fixedly installed on the rotating shaft 6 and rotates and slides with the inner side wall of the regulating cylinder 4. A through shaft 9 is rotatably connected to the top of the rotating sleeve 8. The bottom of the rotating shaft 6 is rotatably connected to the through shaft 9. The rotating shaft 6 and the flow guiding screw ribbon 7 facilitate the rotation of the flow guiding screw ribbon 7 and the rotating shaft 6 as a whole when reflux and discharge are performed, thus ensuring the smoothness of reflux and discharge. The through shaft 9 improves the stability of the rotating shaft 6 installed on the regulating cylinder 4.

[0027] Specifically, valves 17 are installed on the top of the discharge tank 1, as well as on the discharge pipe 2 and the return pipe 3, so that secondary flow rate can be easily controlled through valves 17.

[0028] In use, the discharge tank 1 is connected to the discharge port of the catalytic distillation tower reflux tank. Then, the two discharge ports 5 are adjusted to connect with the discharge pipe 2 and the reflux pipe 3 respectively through the adjustment mechanism. Then, the adjustment cylinder 4 is locked by the locking mechanism. Then, the discharge valve of the discharge port of the catalytic distillation tower reflux tank is opened, and the material is returned and discharged through the two discharge ports 5 through the discharge pipe 2 and the reflux pipe 3 respectively.
