Description

Technical Field

[0001] This utility model relates to the field of distillation column technology, specifically to a quick-release distillation column tray installation structure. Background Technology

[0002] Distillation columns are key separation equipment widely used in industries such as chemical engineering, petroleum refining, and pharmaceuticals. They achieve efficient separation by utilizing the differences in volatility of components in a mixture. Their core structure includes the column body, trays (or packing), reboiler, and condenser. During operation, the liquid and gas phases come into counter-current contact within the column, undergoing multiple partial vaporization and condensation processes. Lighter components rise with the vapor and accumulate at the top, while heavier components descend with the liquid and concentrate at the bottom. The trays, as the main structural component of the distillation column, provide support and isolation. Traditional distillation column trays are typically fixed, making disassembly cumbersome and hindering the maintenance process. Utility Model Content

[0003] The purpose of this utility model is to provide a quick-release distillation column tray installation structure to solve the problem mentioned in the background art that traditional distillation column trays are usually fixedly connected, and the disassembly process of the trays is cumbersome during the maintenance of the distillation column, which affects the maintenance process of the distillation column.

[0005] Preferably, a secondary through groove is provided between the fixed edge and the left mounting plate and between the fixed edge and the right mounting plate. The material discharge pipe passes through the fixed sleeve through the left secondary through groove. A main through groove is provided between the two mounting plates. The first screen plate and the second screen plate are correspondingly arranged with the main through groove.

[0006] Preferably, the receiving plate, the first screen plate, the second screen plate, the limiting plate, and the dropping plate are all fixedly connected to the fixing edge and the mounting plate by fixing bolts.

[0007] Preferably, the upper edge of the discharge pipe is correspondingly arranged with the upper edge of the overflow plate, and the upper edges of both the discharge pipe and the overflow plate are located inside the upper edge of the fixed sleeve.

[0008] Preferably, a reinforcing plate is provided inside the fixing sleeve and at the midpoint between the lower surfaces of the two mounting plates.

[0009] Compared with the prior art, the beneficial effects of this utility model are: replacing the traditional fixed connection distillation column tray structure, the tray is designed into several parts, which are fixedly connected by screws, and there is no interference between each part. When the distillation column is overhauled, the corresponding faulty part can be disassembled and replaced.
