Description

A plate distillation column Technical Field

[0001] This invention relates to the field of plate distillation columns, specifically a plate distillation column. Background Technology

[0002] A distillation column is a tower-type gas-liquid contact device used for distillation. It utilizes the property that the components in a mixture have different volatility (i.e., different vapor pressures at the same temperature) to transfer lighter components from the liquid phase to the gas phase, while heavier components from the gas phase transfer to the liquid phase, thus achieving separation.

[0003] A plate column is a type of distillation column, consisting of a typically cylindrical shell and several horizontally arranged trays at regular intervals. The plate distillation column has several trays arranged along its height. Liquid flows from the top to the bottom of the column by gravity, forming a flowing liquid layer on each tray surface. Gas, propelled by pressure differences, flows upwards from the bottom, passing through the liquid layers on each tray to the top. The gas and liquid phases come into contact step-by-step within the column, and the composition of the two phases changes in a stepped manner along the column's height. Technical issues

[0004] Since liquids flow from the top to the bottom of the column by gravity, the trays of existing chemical plate distillation columns are generally fixed inside the column, making it difficult to adjust or replace them, which makes it difficult to adjust the flow rate according to the properties of the liquid.

[0005] The present invention aims to solve the technical problems existing in the prior art, and to this end, a plate distillation column is proposed. Technical solutions

[0006] The purpose of this invention is to provide a plate distillation column to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A plate distillation column includes a distillation column, an adjustment assembly is threadedly connected to one side of the distillation column, the adjustment assembly includes a lead screw, a handle is fixedly connected to one end of the lead screw, a rotating rod is fixedly connected to the other end of the lead screw, a connecting groove is opened on the cylindrical surface of the rotating rod, and a tray assembly is rotatably connected to the other end of the rotating rod, the connecting groove cooperating with the tray assembly.

[0009] As a further aspect of the present invention: the tray assembly includes a sealing plate, which is rotatably connected to a rotating rod. A connecting block is fixedly connected to the inner surface of the sealing plate. The connecting block is located in a connecting groove and slides in contact with the rotating rod. A tray is fixedly connected to the other end of the sealing plate.

[0010] As a further embodiment of the present invention: a feed pipe is fixedly connected to one end of the distillation column, an air inlet pipe is fixedly connected to one side of the distillation column, a valve is fixedly connected to the air inlet pipe, and a discharge pipe is fixedly connected to one side of the distillation column, with a valve being fixedly connected to the discharge pipe. Beneficial effects

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows: the device rotates the handle, which drives the lead screw to rotate. Since the lead screw is threadedly connected to the distillation column, when the lead screw rotates, it moves horizontally, which drives the rotating rod to move. The rotating rod drives the connecting block to move through the connecting groove, and the connecting block drives the tray to move, thus adjusting or removing the tray. The device can easily adjust or remove the tray, control the liquid flow rate according to the liquid characteristics, and adjust the liquid-gas contact time. Attached Figure Description

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0018] The following disclosure provides numerous different embodiments or examples for implementing various structures of the invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0019] Please refer to Figures 1-4. A plate distillation column includes a distillation column 1. An adjustment assembly is threadedly connected to one side of the distillation column 1. The adjustment assembly includes a lead screw 8. One end of the lead screw 8 is fixedly connected to a handle 5, and the other end of the lead screw 8 is fixedly connected to a rotating rod 9. A connecting groove 10 is opened on the cylindrical surface of the rotating rod 9. The other end of the rotating rod 9 is rotatably connected to a tray assembly. The connecting groove 10 cooperates with the tray assembly. This device can easily adjust or remove the trays, control the liquid flow rate according to the liquid characteristics, and adjust the liquid-gas contact time.

[0020] Please refer to Figures 2 and 3. The tray assembly includes a sealing plate 11, which is rotatably connected to a rotating rod 9. A connecting block 12 is fixedly connected to the inner surface of the sealing plate 11. The connecting block 12 is located in the connecting groove 10 and slides in contact with the rotating rod 9. The other end of the sealing plate 11 is fixedly connected to a tray 13. Rotating the handle 5 causes the lead screw 8 to rotate. Since the lead screw 8 is threadedly connected to the distillation column 1, when the lead screw 8 rotates, it moves horizontally, causing the rotating rod 9 to move. The rotating rod 9 moves the connecting block 12 through the connecting groove 10, and the connecting block 12 moves the tray 13, allowing the tray 13 to be adjusted or removed.

[0021] Please refer to Figure 1. One end of the distillation column 1 is fixedly connected to the feed pipe 2, and the other side of the distillation column 1 is fixedly connected to the air inlet pipe 3. The air inlet pipe 3 is fixedly connected to the valve 4. The other side of the distillation column 1 is fixedly connected to the discharge pipe 6, and the discharge pipe 6 is fixedly connected to the valve 7.

[0022] The working principle of this invention is as follows: The device rotates the handle 5, which drives the lead screw 8 to rotate. Since the lead screw 8 is threadedly connected to the distillation column 1, when the lead screw 8 rotates, it moves horizontally, which in turn drives the rotating rod 9 to move. The rotating rod 9 drives the connecting block 12 to move through the connecting groove 10, and the connecting block 12 drives the tray 13 to move. This allows the tray 13 to be adjusted or removed. The device can easily adjust or remove the tray 13, control the liquid flow rate according to the liquid characteristics, and adjust the liquid-gas contact time.
