Multi functional glass continuous distillation experimental deviceDevice features

deviceincludecontinuousThe distillation tower and intermittent distillation tower are two parts, with the two towers operating independently. Double glass distillation tower,The entire tower is made of visible transparent glass material, which allows for clear observation of the gas-liquid flow inside the tower.The outer wall of the tower is made of transparent conductive film using new insulation technology, and electrically heated insulation is used to offset heat loss. There is also a glass sleeve covering the exterior of the tower for insulation.Two metering pumps feed the continuous distillation tower.Automatic temperature control of tower kettle, digital display of instruments; Two sections of the tower are manually insulated. Temperature measurement of tower top kettle, instrument digital display. Reflux ratio self-control, instrument digital display.

Computer data acquisition interface and software, using high-precision process control instruments and data control and acquisition configuration software for high reliability and small sizeAIDCSDistributed Control System (Instrumentation)+serial communication+In the upper monitoring computer mode, connect to the computer for remote control and display.Real time display and monitoring of process flow and process parameters, canControl and collect data such as temperature and reflux ratio.Implement data collection, processing, and analysisHistorical data query and export; Alarm settings, queries, and records.
