Description

Technical Field

[0001] This utility model relates to the field of differential reaction system technology, specifically to a gas-liquid separation device for a differential reaction system. Background Technology

[0002] In differential reaction processes such as continuous flow catalytic reaction and gas-liquid two-phase synthesis, the gas-liquid mixture generated by the reaction needs to be separated in a timely manner to achieve separate collection and subsequent processing of gaseous and liquid products.

[0003] Existing gas-liquid separation devices have significant drawbacks: traditional cylindrical separation chambers are prone to interference with the natural stratification of gas and liquid due to turbulent flow fields, resulting in "droplets entrained in the gas phase and bubbles mixed in the liquid phase," which reduces product purity; the lack of precise temperature control design for the separation chamber makes it impossible to regulate the temperature inside the chamber according to the thermodynamic characteristics of the reaction system, thus hindering the optimization of separation efficiency; liquid phase sampling and wastewater discharge require shutdown and disassembly of the chamber, which not only compromises the system's sealing performance but also reduces production continuity, making it difficult to meet the technical requirements of high efficiency, precision, and continuity for differential reaction systems. Utility Model Content

The gas-liquid mixing inlet assembly is connected to the top of the gas-liquid separation chamber for introducing the gas-liquid mixture to be separated. The gas phase discharge assembly is located on the upper side of the gas-liquid separation chamber for discharging the separated gas phase product. The liquid phase discharge assembly is located on the lower side of the gas-liquid separation chamber for discharging the separated liquid phase product. The temperature-controlled medium conduit is spirally wound around the outer wall of the gas-liquid separation chamber for circulating a hot or cold medium to regulate the temperature inside the chamber.

[0005] Preferably, the gas-liquid mixing inlet assembly includes: a gas-liquid mixing inlet pipe and a first control valve; one end of the gas-liquid mixing inlet pipe is connected to the top of the gas-liquid separation chamber, and the other end is used to connect to an external gas-liquid mixture conveying pipeline; the first control valve is connected in series on the gas-liquid mixing inlet pipe and is used to regulate the feed flow rate of the gas-liquid mixture.

[0006] Preferably, the gas phase discharge assembly includes: a gas phase outlet and a gas phase outlet pipe; the gas phase outlet is located on the upper side of the gas-liquid separation chamber; one end of the gas phase outlet pipe is connected to the gas phase outlet, and the other end is used to connect to an external gas phase product collection pipeline.
