[0002] A reboiler is a device that vaporizes a liquid again. Its structure is similar to that of a condenser, but one is used for cooling, while a reboiler is used for heating and vaporization. Reboilers are often used in conjunction with fractionating towers or rectification towers. A reboiler is a special heat exchanger that can exchange heat and has a vaporization space. The material level in the reboiler is at the same height as the fractionating tower level. The liquid phase is supplied from the bottom line of the tower to the reboiler. Usually 25-30% of the liquid phase is vaporized in the reboiler, and the vaporized two-phase flow is sent back to the fractionating tower. The gas phase component in the return tower passes upward through the tower plate, while the liquid phase component falls back to the bottom of the tower. The current reboiler is often installed by docking it to the side of the distillation tower by a crane. The operation is relatively complicated and time-consuming and labor-intensive. Therefore, a reboiler for a distillation tower is needed.
