Continuously discharging reboiler

Abstract

The invention provides a continuously discharging reboiler which comprises a tower kettle (1). A heating device is arranged inside the tower kettle; a feed inlet (2) is arranged at the top of the tower kettle, and a discharge outlet (3) is arranged at the bottom of the tower kettle; the top of the tower kettle is connected with a rectifying column (4); the top of the rectifying column is connected with a return pipe (5); a temperature sensor (6) is mounted in the tower kettle and is connected with a temperature controller (7); and the temperature controller is connected with the heating device. According to the invention, the temperature sensor and the temperature controller are employed to accurately control heating temperature, and the discharge outlet is arranged at the bottom of the tower kettle, which enables discharging to be convenient and continuous production to be realized.

Description

technical field [0001] The invention relates to a chemical machinery, in particular to a continuous discharge reboiler. Background technique [0002] Precision rectification and vapor-liquid equilibrium determination are indispensable methods and basic data in the research process of chemical and pharmaceutical production. There are many types of precision rectification devices, and the internal structures of rectification devices are various. The structure of precision rectification devices currently used can be divided into packing type and plate structure, and can be divided into continuous type and batch type distillation devices according to the operation mode. The distillation device is generally composed of a round-bottomed flask, a rectifying column, a three-way distillation head and a condenser tube. The round-bottomed flask is used for heating. There are two problems in the process of use. One is that the heating area at the bottom is small and the heating spee...

Problems solved by technology

The distillation device is generally composed of a round-bottomed flask, a rectifying column, a three-way distillation head and a condenser tube. The round-bottomed flask is used for heating. There are two problems in the process of use. One is that the heating area at the bottom is small and the heating speed is slow. Second, the bottom discharge is difficult

In order to realize continuous distillation at the bottom in the laboratory, the bottom discharge of the tower is often realized by negative pressure suction. This method is used to realize the discharge of the bottom of the tower, but the process is complicated, not only buffer devices are required, but also a vacuum system is required. Sometimes the material will be taken away by the vacuum system, and at the same time, the heating speed is found to be slow
