Technical Field

[0001] The utility model relates to the technical field of distillation tower accessories, in particular to a high-efficiency heat transfer type distillation tower plate component. Background Art

[0002] A distillation tower is a tower-type gas-liquid contact device, and is also a widely used mass transfer and heat transfer device in petrochemical production. It is mainly used for efficient distillation. Its working principle is to use the different volatilities of the components in the mixture, that is, the different vapor pressures of the components at the same temperature, to transfer the light components in the liquid phase to the gas phase, and the heavy components in the gas phase to the liquid phase, thereby achieving the purpose of separation. The plate assembly is the core component of the distillation tower, which is used to make the two fluids in close contact and exchange mass between the two phases to achieve the purpose of separating the components of the liquid mixture or gas mixture. The distillation efficiency of the distillation tower depends largely on the structure of the plate assembly.

The utility model has the function of fully contacting steam and liquid to improve the distillation efficiency, and the exhaust cap and valve stem are provided to allow the steam to flow through the sieve holes and the exhaust holes to contact the liquid, thereby increasing the contact area and improving the distillation efficiency, and the downcomer and the baffle can effectively reduce the gap at the liquid reflux port between the plate bodies, and effectively reduce the circulation of steam at the reflux port. However, the distillation tower tray assembly is not convenient for further preventing the gas phase from bypassing the tray through the downcomer, and is not convenient for increasing the contact time between the gas phase and the liquid phase.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a high-efficiency heat transfer type distillation tower plate assembly is proposed. Utility Model Content
