Description

Technical Field

[0001] The utility model relates to the technical field of chemical industry, in particular to a multi-layer anti-leakage structure of a plate fractionation tower. Background Art

[0002] A fractionation tower is a tower-type vapor-liquid device for distillation, also known as a distillation tower. There are two main types of fractionation towers: plate towers and packed towers. According to the operation type, they can be divided into continuous fractionation towers and intermittent fractionation towers. The size of the sieve holes on the plates of plate fractionation towers is mostly fixed and cannot be adjusted. The size of the sieve holes required for different liquids is different. For example, for some liquids with higher viscosity, too small a sieve hole can easily cause clogging of the sieve hole. If the size of the sieve hole remains unchanged, the requirements for the properties of the required liquid are too single and it does not have wide applicability.

[0003] For example, announcement number CN202210501729.1 discloses "A Plate Distillation Tower", which has a slider and a groove on the edge of the sieve hole. The size of the sieve hole is controlled by changing the gas flow rate, which makes the plate distillation tower have a wider range of applications.

[0004] Although the size of the sieve holes can be controlled by changing the gas flow rate to avoid clogging of the sieve holes, the expansion of the sieve holes will increase the amount of liquid passing through, and will also cause the liquid on the pedals in the distillation tower to leak due to the increase in liquid, which is not conducive to the use of the plate distillation tower.
