The working principle of the multifunctional alcohol recovery concentrator can be divided into the following core modules based on different designs:
1. Distillation and evaporation system
High temperature evaporation: Heating the waste solution containing alcohol to 40-85 ℃ through a heating system, causing the alcohol molecules to preferentially evaporate into a gaseous state and separate from other components. During this process, the equipment adopts a vacuum negative pressure environment (vacuum degree ≥ 620mmHg) to reduce the boiling point of alcohol and improve evaporation efficiency.
Secondary steam utilization: The secondary steam generated by evaporation is converted into liquid state through a condenser, and some of it is returned to the extraction tank as new solvent for recycling, reducing the consumption of new solvent.
2. Condensation and recovery system
Multi stage condensation: The evaporated alcohol vapor is cooled by a multi-stage condenser and re liquefied through low-temperature condensation, achieving the separation of alcohol and gas impurities. During the condensation process, it may be combined with the structure of the distillation tower, causing high concentration alcohol to accumulate at the top and low boiling point impurities to settle at the bottom.
Circulating purification: The liquefied alcohol is temporarily stored in a recovery tank, and some equipment undergoes secondary purification through a regeneration tower to further increase the alcohol concentration.
3. Circulation and Separation Control
Closed loop operation: The equipment adopts an external circulation design, where the vapor phase substance in the evaporator is condensed and refluxed to the system, forming a continuous cycle and reducing energy consumption. Dynamically adjust the vacuum degree (0.03-0.09MPa) and temperature to adapt to different material properties.
Impurity discharge: Water or other residues are periodically discharged through the discharge outlet to ensure stable solvent density in the system and avoid affecting recovery efficiency.
4. Application scenario characteristics
Adaptability: Supports the recovery of various organic solvents such as ethanol and methanol, with a processing capacity of up to 200-500kg/h depending on the model.
Energy saving: By utilizing waste heat recovery and closed-loop design, energy consumption is reduced, resulting in a significant overall energy-saving rate.
This device achieves efficient recovery and reuse of alcohol through physical phase transition and precision control technology, and is suitable for fields such as medicine and chemical engineering.
