Description

Technical Field

[0001] The utility model relates to the technical field of redistributors, in particular to a distillation tower with a redistributor. Background Art

[0002] The redistributor of a distillation tower is generally assembled from two devices, a collector and a distributor. Existing redistributors first collect the wall flow on the inner wall of the distillation tower, and then redistribute the collected liquid downward through the redistributor, and transfer mass with the rising gas phase in the packing layer to achieve fractionation. However, traditional redistributors wait for the wall flow to passively flow to the liquid collector below. The passive wall flow collection efficiency is low. Between the upper packing layer and the lower packing layer, there will still be a lot of wall flow on the inner wall of the distillation tower corresponding to the redistributor, which affects the utilization rate of the liquid phase. Patent documents have been made to improve this.

[0003] For example, Chinese patent CN219764513U discloses a redistributor for a distillation tower, comprising: a scraping device, a liquid collecting cup and a rotating shaft device, wherein the rotating shaft device comprises a rotating shaft, the bottom end of which is fixedly mounted in the center of the liquid collecting cup, and a plurality of scraping devices are evenly distributed circumferentially on the side wall of the liquid collecting cup, wherein the scraping device comprises a scraper blade and a flow trough, wherein the scraper blade is tiltedly fixed on the side wall of the liquid collecting cup, and the flow trough is fixed on the lower edge of the scraper blade, and a plurality of first leak holes are evenly distributed circumferentially on the bottom of the liquid collecting cup. The scraper blade and the flow trough of the utility model are integrally formed, and actively scrape the wall flow under the drive of the rotating shaft, and redistribute the collected liquid evenly into the distillation tower.

[0004] Although the collected liquid in the above patent is evenly distributed in the distillation tower, the rotating shaft of the above patent will pass through the packing layer during installation, so that the rotating shaft continues to rotate in the packing layer, which is not convenient for installation and may even affect the use of the packing layer. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a distillation tower with a redistributor, which solves the problem that the rotating shaft passes through the packing layer during installation, causing the rotating shaft to continuously rotate in the packing layer, which is inconvenient to install and may even easily affect the use of the packing layer.

[0006] To achieve the above objectives, the utility model is implemented through the following technical solutions: a distillation tower with a redistributor, comprising a distillation tower body, wherein packing layer bodies are arranged above and below the inside of the distillation tower body, a water tank is fixedly connected between the two sides of the inner cavity of the distillation tower body and between the two packing layer bodies, a rotating rod is rotatably connected to the bottom of the inner cavity of the water tank through a bearing, one end of the rotating rod penetrates the water tank and extends to the top of the water tank, a fixed sleeve is fixedly connected to the outer surface of the rotating rod and is located outside the water tank, a connecting plate is fixedly connected to the outer surface of the fixing sleeve, a scraping plate is fixedly connected to one side of the connecting plate, and a driving mechanism compatible with the rotating rod is arranged on one side of the distillation tower body.

[0007] Preferably, the driving mechanism includes a mounting frame, which is fixedly connected to the outer surface of the distillation tower body, and a motor is fixedly connected to one side of the mounting frame. The output shaft of the motor is fixedly connected to a rotating rod through a coupling, one end of the rotating rod passes through the distillation tower body and extends to the interior of the distillation tower body, and a sealed rotating port that matches the rotating rod is opened on one side of the distillation tower body.

[0008] Preferably, one end of the rotating rod extending into the interior of the fractionation tower body is fixedly connected to a first bevel gear, and a second bevel gear matched with the first bevel gear is fixedly connected above the outer surface of the rotating rod.

[0009] Preferably, a water storage frame is fixedly connected to the lower part of the front portion of the scraper plate, and a guide pipe is connected to one side of the water storage frame.

[0010] Preferably, a rectangular opening adapted to fit the rotating rod and the flow guide tube is provided on the top of the water storage tank.

[0011] Preferably, the front and rear portions of the water storage tank are both connected to a plurality of distribution pipes, and the lower portion of the outer surface of the distribution pipes is connected to a plurality of drainage holes.

[0012] Beneficial Effects
