AI Technical Summary

Technical Problem

During the secondary recycling of ethanol, the existing distillation equipment consumes a large energy consumption and has low separation efficiency, making it difficult to effectively separate low-concentration ethanol.

Method used

A low-concentration ethanol filtration device is designed, adopting a large flow rate and multiple frequency filtering method. Through the multiple flow diversion of the deflector plate and the frequent contact of the heated pipe, the low-concentration ethanol vaporizes in the heated environment and is discharged through the exhaust port, and the water is discharged through the drain pipe.

Benefits of technology

Compared with traditional distillation equipment, the device consumes less energy and has better operating continuity, achieving efficient separation of low concentrations of ethanol.
