Description

Technical Field

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

[0002] A distillation column is a key piece of equipment used to separate different components in a mixture. It is widely used in many fields such as petrochemicals, chemical industry, pharmaceuticals, and food and beverage. The trays in a distillation column are key components for realizing gas-liquid mass transfer and separation processes. The trays provide sufficient space and surface for the rising gas phase and the descending liquid phase to make contact, which is conducive to the diffusion and exchange of substances between the two phases.

[0003] In existing technologies, during the use of distillation column trays, gas and liquid need to diffuse and exchange on the tray surface. However, the liquid, falling under gravity, is difficult to distribute evenly on the tray surface, which affects the diffusion and exchange efficiency. Furthermore, after prolonged use, it is inconvenient to disassemble and clean the trays, which also affects their performance. Therefore, this application designs a distillation column tray.
