Description

Technical Field

[0001] The utility model relates to the technical field of installation of a tray assembly of a distillation tower, in particular to an installation device of a tray assembly of a distillation tower. Background Art

[0002] A distillation tower is a tower-type gas-liquid contact device that performs distillation. By utilizing the different volatilities of the components in a mixture—that is, the different vapor pressures of the components at the same temperature—the light components in the liquid phase are transferred to the gas phase, while the heavy components in the gas phase are transferred to the liquid phase, thereby achieving separation. Distillation towers are also a widely used mass and heat transfer device in petrochemical production. While both equilibrium distillation and simple distillation can achieve a certain separation effect, they cannot separate a mixture into a certain amount of high-purity products. In petrochemical production, very high-purity products are often required, and these high-purity products can be obtained through the distillation process. A plate tower is a widely used gas-liquid mass transfer device consisting of a typically cylindrical shell with a number of plates arranged horizontally at regular intervals. When a plate tower is operating normally, liquid flows from top to bottom through each layer of plates under the action of gravity and is discharged from the bottom of the tower; gas, driven by pressure difference, passes through each layer of plates from bottom to top through the openings evenly distributed on the plates and is discharged from the top of the tower. A certain amount of liquid is stored on each plate, and when the gas passes through the liquid layer on the plate, the two phases come into contact and transfer mass. For example, the Chinese utility model patent with patent number CN218011146U discloses a plate tower assembly for a distillation tower. When the bubble cap is connected to the top of the riser, it is only necessary to fix the integrated frame to the plate body through a fixing mechanism. At this time, the top of each riser is respectively located in a bubble cap, so that the riser and the bubble cap can play a normal gas guiding role. At the same time, a number of long strip-shaped air diffusion holes are vertically opened at the bottom of the bubble cap, which can cut and disperse the gas, thereby enabling the gas phase to better achieve heat exchange with the liquid phase.

[0003] There are still some problems when using the above device. When using a distillation tower for distillation, in order to obtain different distillation products, different numbers of tower plates often affect the distillation efficiency. Therefore, the number of tower plates needs to be adjusted according to actual needs. At the same time, some distillation towers are as high as tens of meters. Installing the tower plates directly on the distillation tower body is inconvenient for staff to operate. Utility Model Content

[0004] In response to the above technical problems, the utility model provides a tray assembly installation device for a distillation tower, which is characterized by comprising a fixed support structure, a tray main structure, and a bottom fixed structure. Fixed support structures are installed on both sides of the tray main structure, and a bottom fixed structure is installed at the bottom of the fixed support structure.

[0005] The main structure of the tower plate consists of a tower plate body, air holes, overflow weirs, and downcomers. An overflow weir is installed on one side of the tower plate body, and downcomers are provided on the side of the overflow weir. Several air holes are provided on the surface of the tower plate body.

[0006] The fixed support structure is composed of a support column A, a support column B, and a fixed splint. Several fixed splints are installed on the inner side of the support column A, and several fixed splints are installed on the inner side of the support column B. The fixed splints on both sides are positioned opposite to each other.

[0007] The bottom fixing structure consists of a bottom plate, a through hole, a bottom fixing plate A, a bottom fixing plate B, a limiting column A, and a limiting column B. The bottom fixing plate A is installed on the inner side of the bottom of the support column A, and the other side of the bottom fixing plate A is installed on the inner side of the bottom of the support column B. The bottom fixing plate B is installed below the bottom fixing plate A. One side of the bottom fixing plate B is installed on the inner side of the bottom of the support column A, and the other side of the bottom fixing plate B is installed on the inner side of the bottom of the support column B. The bottom plate is inserted between the bottom fixing plate A and the bottom fixing plate B. A plurality of through holes are opened through the surface of the bottom plate. The limiting column A is installed on one side of the bottom plate, and the limiting column B is installed on the other side of the bottom plate.

[0008] The tower plate body is inserted into the fixed clamping plates on both sides, and the insertion directions of the two tower plate bodies adjacent to each other are opposite to each other.
