Application

This equipment is suitable for the recovery of dilute alcohol in industries such as pharmaceuticals, chemicals, and food, as well as for the distillation of products such as methanol, which is beneficial for reducing production costs and improving economic benefits.

Working principle

The equipment is to use the principle of the boiling point of alcohol is lower than that of water and other solution .It heats a dilute alcohol solution at a temperature slightly above the boiling point of alcohol, which vaporizes the alcohol and some of the water .The vapor mixture of alcohol rises along the tower packing. Under the action of the filler，The vapor mixture of alcohol and the backflow liquid from the top of the tower fully vapor-liquid contact for mass and heat transfer exchange , so that the content of ethanol in the rising vapor body continues to increase, and the ethanol content of the recirculating liquid in the column decreases continuously and returns to the still.Alcohol vapors go to the condenser through the pipe connected through the top of the tower，and condense into concentrated alcohol.The unqualified continues to distillation, and residual liquid in the kettle discharges.

This device can distill dilute alcohol at 30-50 % to 90-95%, and the residual liquid discharge has low alcohol content, which meets environmental protection requirements
