Embodiment 1

[0052] like figure 2 As shown, a device for separating the middle boiling components of a complex system and returning the low boiling components to the original system, including a reactor interface 1, a first liquid collection device 4, a first temperature control system 6, a tail gas collection device 7, The second temperature control system 8 , the second liquid collection device 11 and the third temperature control system 13 . Wherein, the first liquid collection device 4 and the second liquid collection device 11 are both spherical containers; the first temperature control system 6 and the second temperature control system 8 are serpentine condensers, and the temperature control method is the temperature control of circulating water at a specific temperature The third temperature control system 13 is a straight condenser, and the temperature control mode is temperature control of circulating water at a specific temperature; the tail gas collection device 7 is a spherica...

Embodiment 2

[0057] The method of adopting the device described in embodiment 1 to separate the middle boiling components of the complex system and making the low boiling components return to the original system comprises steps as follows:

[0058] (1) Close all valves in the device first, and connect the reactor interface 1 to the reactor before the system starts to react. After the connection is completed, open the first valve 3, so that the gas in the system passes through the first valve 3 and the first liquid is collected in sequence. The device 4, the first temperature control system 6, the exhaust gas collection device 7 and communicated with the outside atmosphere;

[0059] (2) After the reaction starts and reaches stability, adjust the first temperature control system 6 to make the low-boiling components reflux, avoiding the low-boiling components being collected by the tail gas collection device 7 and causing losses, so that the system reaches stability; The boiling component is ...

Abstract

The invention relates to a method and device for medium boiling components of separating complex systems and returning low boiling components to original systems. The separation of the medium boilingcomponents is achieved through adjusting a temperature control system, and the low boiling components are sent back to the original systems. The separating device mainly consists of a reactor interface, a valve, a three-way device, the temperature control system, a liquid collector and an exhaust gas collection device. The separating device can separately achieve condensation of the medium boilingcomponents and the low boiling components through adjusting parameters of two temperature control systems. And then the medium boiling components are separated from the systems and the low boiling components are sent back to the original systems through controlling the valve. The separating device is simple in principle, convenient to operate, wide in application scope, and can be made into large, medium and small equipment according to different reaction systems, and can widely use in various reaction systems without distillation towers to achieve good separation of boiling components and improve reaction efficiency.

Description

technical field [0001] The invention relates to a special separation device and method for separating specific components from complex systems, belonging to the field of separation and purification of chemical chemicals. Background technique [0002] When a liquid substance is heated, the molecules of the substance escape from the surface of the liquid due to molecular motion, forming vapor pressure. As the temperature rises, the vapor pressure increases. When the vapor pressure is equal to the atmospheric pressure or the given pressure, the liquid boils. The temperature at this time is called the boiling point of the liquid. Every pure liquid organic compound has a fixed boiling point at a certain pressure. Liquid mixtures with a large difference in boiling point (such as a difference of 30°C) can be separated by distillation. If liquids with large boiling points are distilled, the ones with lower boiling points are distilled first, and the ones with higher boiling points...
