Description

Technical Field

[0001] This utility model belongs to the technical field of distillation columns and their accessories, and in particular relates to a liquid distributor for distillation columns. Background Technology

[0002] Distillation columns are one of the most common and important purification devices in the modern chemical industry. They are pagoda-shaped and achieve separation through continuous partial vaporization and condensation. They utilize the volatility of each component in the mixture to obtain different products at the top and bottom of the distillation column. The most important component of a distillation column is the liquid distributor fixed at the top, which distributes the liquid entering the distillation column evenly.

[0003] Chinese patent application CN222829084U discloses a distributor for distillation columns, belonging to the field of distillation column technology. It mainly addresses the problems of inconvenient installation and maintenance, and poor distribution uniformity in existing distributors. Its structure includes a fixed frame and a distribution trough. The fixed frame is provided with a slot, and a second locking block is fixedly connected to the side end of the distribution trough, the second locking block engaging with the slot. The middle part of the distribution trough is concave, and several second water passages are provided at the middle of the side wall of the distribution trough. Second water passages are provided at both ends of the distribution trough, and several drain pipes are provided at the bottom of the second water passages. This distributor for distillation columns uses a slot inside the fixed frame to engage with the second locking block, and then uses a lug to engage with the side wall of the distribution trough. A retaining ring is also provided on the fixed frame to fix the water inlet channel and the distribution trough within the fixed frame, facilitating manual installation and maintenance.

[0004] The aforementioned distributor for a distillation column has an internal water inlet channel connected to distribution troughs on both sides. Water passages are provided at the bottom of both the inlet channel and the distribution troughs to distribute water. However, this distributor requires careful management to prevent water overflow during use. Overflowing water flows out through gaps in the inlet channel, resulting in uneven distribution. Furthermore, the distributor handles diverse liquid types, and distillation columns often distribute multiple solutions in a single distribution cycle. This distributor can only handle one solution at a time, requiring replacement of other solution supply lines for different solutions, which is time-consuming and prone to leakage. Therefore, we provide a distillation column liquid distributor to address these problems. Utility Model Content

[0015] This utility model has the following beneficial effects:

[0016] This invention features a liquid distribution ring and a liquid distribution assembly. The liquid distribution ring is circular, with six water tanks arranged in a ring array on its sidewall. Water inlet assemblies are installed on the outer sidewall of the liquid distribution ring corresponding to the center of each water tank. The liquid distribution assembly is located inside the liquid distribution ring and includes a liquid distribution box rotatably connected to the ring. A liquid distribution plate is embedded in the bottom of the box, and a liquid distribution pipe is embedded in the sidewall of the box. An outlet hole is provided on the inner sidewall of the water tank corresponding to the liquid distribution pipe. The water inlet assembly includes a water inlet pipe embedded in the outer sidewall of the liquid distribution ring, and an electric switch valve is installed on the water inlet pipe. During use, the inlet... The water pipe is connected to the solution replenishment system, thereby enabling the input of various types of solutions into the water tank of the distribution ring. Then, driven by the drive component, the distribution box rotates inside the distribution ring. When the sealing sleeve two on the inlet hole of the distribution box is aligned with the sealing sleeve one on the outlet hole on the inner wall of the distribution ring, the inlet hole and outlet hole are connected to each other. The solution in the water tank then flows into the distribution box through the sealing sleeve one and the sealing sleeve two, and flows out through the distribution plate at the bottom of the distribution box, thus achieving the effect of distributing the solution.

The drive motor is fixedly installed in the upper side wall of the liquid distribution ring. During use, the drive motor operates, causing the bevel gear on its shaft to rotate. Because the bevel gear meshes with the drive ring, the drive ring also rotates, thus driving the liquid distribution tank to rotate within the liquid distribution ring. This aligns the liquid inlet hole on the liquid distribution tank with the liquid outlet holes on different water tanks on the liquid distribution ring. Furthermore, during the rotation of the liquid distribution tank, the first sealing sleeve on the outlet hole, due to its elasticity, abuts against the outer wall of the liquid distribution tank, achieving a sealing effect. Similarly, the second sealing sleeve on the inlet hole abuts against the inner wall of the liquid distribution ring, also achieving a sealing effect. Therefore, no leakage or seepage occurs. Both the first and second sealing sleeves are made of wear-resistant polytetrafluoroethylene (PTFE). Attached Figure Description

[0028] Please see Figure 1-4 This utility model is a liquid distributor for a distillation column, including a liquid distribution ring 1 and a water inlet assembly 2. The water inlet assembly 2 can replenish and store the solution in the water tank 103 in the liquid distribution ring 1.

[0029] Specifically, the upper sidewall of the liquid distribution ring 1 is provided with a cover plate groove 102, and the bottom sidewall of the cover plate groove 102 is provided with a water tank 103. There are six water tanks 103 in total, and the six water tanks 103 are arranged in a ring array structure. A water inlet component 2 is installed on the outer wall of each water tank 103. The water inlet component 2 includes a water inlet pipe 201 embedded and communicating with the water tank 103.

[0030] Furthermore, the inner wall of the water tank 103 is provided with a liquid outlet hole 103a, and a cylindrical sealing sleeve 104 is bonded to the inner wall of the liquid outlet hole 103a.

[0031] The operation process of this embodiment is as follows: When in use, the water inlet pipe 201 is connected to the solution replenishment system pipeline, and the electric switch valve 202 is opened. At this time, the solution replenishment system pipeline is connected to the water tank 103 in the liquid distribution ring 1 through the water inlet pipe 201, thereby achieving the effect of inputting various different types of solutions into the water tank 103 of the liquid distribution ring 1. Example 2

[0032] Please see Figure 5 Based on Example 1, a liquid distribution assembly 3 is also provided. The liquid distribution assembly 3 can receive the solution in the water tank 103 of the liquid distribution ring 1 and input it into the liquid distribution box 301, and then distribute the solution through the liquid distribution plate 304.

[0033] Specifically, the liquid distribution ring 1 has an annular groove 101 inside, and the annular groove 101 is used for the installation of the liquid distribution assembly 3. The liquid distribution assembly 3 includes a liquid distribution box 301 disposed in the annular groove 101.

A rotating rod 403a is fixedly installed at the shaft of the bevel gear 403, and the rotating rod 403a is connected to the motor shaft of the drive motor 402 by a coupling.

[0039] The operation process of this embodiment is as follows: When in use, the drive motor 402 works, which drives the bevel gear 403 on the shaft end to rotate. Since the bevel gear 403 meshes with the drive ring 401, the drive ring 401 will also rotate. This achieves the effect of pushing the liquid distribution box 301 to rotate inside the liquid distribution ring 1, that is, pushing the liquid inlet hole 301d on the liquid distribution box 301 to connect with the liquid outlet hole 103a on the different water tanks 103 on the liquid distribution ring 1.
