Description

TECHNICAL FIELD

[0001] The utility model relates to condensing equipment field, concretely is a laboratory with arc plate reflux device. BACKGROUND

[0002] Gas condensation is a common process in chemical production, and a typical representative is the overhead condensation in rectification process. The steam generated by rectification is partially or totally refluxed to the rectification tower through the overhead condensation part, and high-purity products are obtained through multiple reflux. Therefore, the research on the overhead condenser has always been the focus of attention. The traditional overhead condenser usually adopts a tube heat exchanger, but the tube heat exchanger has low heat exchange efficiency and large equipment size. Later, there was an innovation to use a plate heat exchanger as an overhead condenser. However, the plate heat exchanger has a square structure and limited pressure resistance.
