Description

Technical Field

[0001] This utility model relates to the technical field of vapor-liquid separation equipment, specifically a stripping tower vapor-liquid separator. Background Technology

[0002] Stripping towers are key equipment in petrochemical, MVR evaporation, and other systems. They are mainly used to efficiently separate gas-liquid mixtures, protect downstream equipment, and improve product quality.

[0003] Traditional packed stripper gas-liquid separators typically use a support grid to hold the packing material inside the tower. Without a packing pressure grid at the top, the packing stability is low. However, the presence of a packing pressure grid improves stability. Currently, the packing pressure grid is generally a single-plate structure. Removing, cleaning, or replacing the entire grid requires opening the top cover, which is inconvenient due to the presence of an exhaust pipe at the top. Furthermore, if a distributed packing pressure grid is used, it is prone to tipping or sliding during operation. Therefore, an improved technology is urgently needed to address this problem in existing technologies. Utility Model Content

[0004] The purpose of this invention is to provide a stripping tower vapor-liquid separator to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a stripping tower vapor-liquid separator, comprising a lower cylinder, an upper cylinder, a packing support grid, and a packing pressing grid. The top end of the lower cylinder is connected to the bottom end of the upper cylinder via a flange. A ring plate is clamped at the connection between the lower and upper cylinders. A packing support grid is provided on the inner side of the ring plate. Several uprights are vertically arranged on the upper surface of the packing support grid. A crossbar is connected between adjacent uprights. Packing is filled on the packing support grid. There are several packing pressing grids, all of which form a circular grid structure. The packing pressing grid is pressed onto the packing. The packing pressing grid has through holes, which cooperate with the uprights. The uprights pass through the through holes of the packing pressing grid.

[0019] Please see Figure 1-3 This utility model provides a technical solution: a stripping tower vapor-liquid separator, comprising a lower cylinder 1, an upper cylinder 2, a packing support grid 3, and a packing pressing grid 4. The top end of the lower cylinder 1 is connected to the bottom end of the upper cylinder 2 via a flange 5. A ring plate 6 is clamped at the connection between the lower cylinder 1 and the upper cylinder 2. The packing support grid 3 is arranged inside the ring plate 6. Several uprights 7 are vertically arranged on the upper surface of the packing support grid 3, and horizontal bars 8 are connected between adjacent uprights 7. Packing 9 is filled on the packing support grid 3. There are several packing pressing grids 4. The packing press grid 4 forms a circular grid structure, which is pressed on the packing. The packing press grid 4 has through holes 10, which are matched with uprights 7. The uprights 7 pass through the through holes 10 of the packing press grid 4. Each packing press grid 4 is matched with at least two uprights 7 to ensure the stability of each packing press grid 4. The packing support grid 3 and the packing press grid 4 are both welded together from two layers of mutually perpendicular straight rods / pipes to form a grid structure, thereby preventing the packing 9 from passing through.

[0020] The bottom of the lower cylinder 1 is provided with a drain port 11 to discharge the liquid. The lower cylinder 1 is provided with an air inlet 12 and a spare port 13 on both sides. The air inlet is used for the entry of the gas-liquid mixture. The side wall of the lower cylinder 1 is also provided with an observation port 14 to observe the internal state of the separator when it is working. Several support legs 15 are connected to the periphery of the lower cylinder 1 to achieve overall lifting and support fixation.

[0021] The top of the upper cylinder 2 is conical and has an exhaust port 16 to allow gas to be discharged. A hand hole 17 and a discharge port 18 are respectively provided on one side of the upper cylinder 2. The discharge port 18 is located below the hand hole 17. The hand hole is used for adding the packing 9 and inserting or removing the packing pressing grid 4. The discharge port 18 is used for replacing the packing 9, thereby allowing the packing 9 to be discharged.

[0022] Installation method and operating principle: Place the ring plate 6, with the packing support grid 3 on its inner side, onto the flange 5 at the top of the lower cylinder 1. Weld the bottom of the uprights 7, which are interconnected by the crossbars 8, to the packing support grid 3. Then, fit the upper cylinder 2 over the uprights 7 and secure the bottom of the upper cylinder 2 to the lower cylinder 1 using the flange 5, bolts, and nuts. The upper and lower surfaces of the ring plate 6 are connected to the flanges 5 of the upper and lower cylinders 1 through sealing rings to ensure a tight seal. Insert the packing 9 into the upper cylinder 2 through the manhole 17 and support it on the packing support grid 3. The packing 9 can be a Pall ring. Next, place each packing pressing grid 4 into the upper cylinder 2 in sequence through the manhole 17 and connect it to the uprights 7 through the through hole 10, so that the packing pressing grid 4 presses down on the packing 9, completing the installation. Before use, the handhole 17 and discharge port 18 are sealed with sealing plates. The exhaust port 16 is connected to the exhaust pipe, the air inlet 12 is connected to the air inlet pipe, the liquid outlet 11 is connected to the liquid outlet pipe, and the spare port 13 is sealed with a blind flange. During use, the gas-liquid mixture enters the lower cylinder 1 through the air inlet 12. The gas passes through the packing support grid 3 and comes into contact with the packing 9. The packing 9 intercepts droplets and increases the contact area to improve separation accuracy. The gas moves upward and is discharged from the exhaust port 16, while the liquid falls into the lower cylinder 1 and is discharged through the liquid outlet 11. This utility model has a reasonable structure. The packing support grid 3 is vertically equipped with several uprights 7, and there are multiple packing pressing grids 4, each of which is connected to the uprights 7 through through holes 10. The cooperation of the uprights 7 ensures that the packing pressing grid 4 will not tilt or fall, thus ensuring the stability of the packing 9. At the same time, the non-integral structure of the packing pressing grid 4 makes it easy to remove or insert through the handhole 17 and facilitates cleaning.

[0023] Any aspects of this utility model not described in detail are well-known technologies to those skilled in the art.

[0024] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although this utility model has been described in detail with reference to the embodiments, those skilled in the art should understand that modifications and equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
