Description

Technical Field

[0001] The utility model relates to the technical field of distillation towers, in particular to a component inside a distillation tower. Background Art

[0002] A distillation tower is a tower-type gas-liquid contact device for distillation. By utilizing the different volatilities of the components in the mixture, that is, the different vapor pressures of the components at the same temperature, the light components (low-boiling substances) in the liquid phase are transferred to the gas phase, and the heavy components (high-boiling substances) in the gas phase are transferred to the liquid phase, thereby achieving the purpose of separation. The distillation tower is also a mass transfer and heat transfer device that is widely used in petrochemical production.

[0003] However, in the prior art, in the distillation tower assembly, gas entry is usually provided directly by the reboiler. In order to avoid liquid leakage, the reboiler is often set at a higher temperature, which causes the gas to enter the distillation tower too quickly, resulting in liquid flooding. The reboiler has difficulty controlling the gas entry rate within an appropriate threshold. The lack of control over the gas entry rate makes it difficult to maintain the stability of the gas phase, resulting in frequent flooding and leakage, thereby causing low efficiency of the distillation tower.

[0013] 2. In the utility model, when the gas release speed is not fast enough due to the reboiler, the air pressure sensor will sense that the internal gas pressure of sleeve 1 is too low and transmit it to the computer terminal, and then the computer terminal controls the motor to start, the motor drives the connecting shaft to rotate, the gear 1 cooperates with the gear groove to make the gear 2 rotate inside the inner gear, so that the piston moves inside the sleeve 3, and then the reboiler temperature is increased, the gas output efficiency at the gas inlet is improved, the gas enters the distillation tower from the air hole, and the leakage problem is prevented.
