Description

Technical Field

[0001] The utility model relates to the technical field of distillation kettles, in particular to energy-saving recycling equipment for distillation kettles. Background Art

[0002] A distillation kettle is a chemical reactor, which consists of a kettle body, a conical bottom, a heat exchanger, a cooler, a reboiler, a steam generator, a condenser and other components. The distillation kettle is mainly divided into two types: dry distillation kettle and wet distillation kettle. In the dry distillation kettle, the mixture enters the kettle body through heating. After the mixture boils, the saturated steam enters the heat exchanger for cooling, and then enters the condenser after cooling. In the condenser, the steam becomes liquid after cooling and then flows into the container. During the whole process, the components with lower boiling points are first converted into steam, and then cooled into liquid, so as to be separated, while the components with higher boiling points remain in the kettle body until they reach the corresponding boiling point.

[0003] A Chinese patent with announcement number CN213965217U discloses a distillation kettle for CCMP production, which continuously blows cold air into a conversion box through a refrigerator. The high-temperature water vapor will liquefy into small water droplets after being cooled, and fall into the conversion box for storage. The evaporated water is recycled to avoid wasting water resources, thereby improving practicality.

[0004] Although the device can condense steam into liquid water to recycle steam, the steam will carry a certain pressure when discharged from the kettle, and this pressure is not well utilized. In addition, the steam carries high heat, and the direct condensation of the steam will not only cause heat waste, but also slow down the condensation efficiency. To this end, we provide a distillation kettle energy-saving recovery device to solve the above problems. Utility Model Content
