Description

Technical Field

[0001] The present application relates to the technical field of distillation towers, and in particular to a cooling device for a distillation tower. Background Art

[0002] A distillation tower is a tower-type gas-liquid contact device for distillation. It utilizes 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 (low boiling substances) in the liquid phase to the gas phase, and the heavy components (high boiling substances) in the gas phase to the liquid phase, thereby achieving the purpose of separation. The distillation tower is also a mass transfer and heat transfer device that is extremely widely used in petrochemical production.

[0003] Announcement No. CN 218553169 U discloses a distillation tower cooling device, which is equipped with a steam condensing component to allow the steam that has not been completely cooled and liquefied to flow into the inlet reflux pipe, and the cooled liquid can flow into the inlet steam collecting tube through the condenser pipe to avoid the high gas pressure in the steam collecting tube and extend the service life. By providing a cooling circulation component, the condenser pipe and the steam collecting tube can be cooled simultaneously to improve the cooling effect, and water can be circulated and sprayed to avoid waste of water resources, and the device is highly practical.

[0004] However, there are some defects in the above scheme: in the above scheme, the steam that has not been completely cooled and liquefied is directed into the reflux pipe by setting a reflux pipe condenser for re-condensation, but the steam collecting tube is difficult to quickly condense the incoming steam, and the heat exchange efficiency is low, resulting in low cooling efficiency, and the cooling water is circulated before sufficient heat exchange, resulting in low utilization rate.
