What is the main purpose of JH series alcohol recovery tower
source：www.sjbyj.com Release time：2026-09-28
The JH series alcohol recovery tower belongs to the packed distillation equipment. Its core purpose is to purify the low concentration dilute ethanol waste liquid generated in the production process by distillation, recover high concentration ethanol for recycling, and be compatible with the distillation recovery of some other low boiling point organic solvents. It is widely used in industries such as pharmaceuticals, traditional Chinese medicine extraction, food, and chemical engineering.
1. Pharmaceutical/traditional Chinese medicine extraction industry (most mainstream use): The traditional Chinese medicine alcohol extraction, percolation, reflux concentration processes produce a large amount of dilute alcohol mother liquor, which contains impurities such as drug residue and plant extracts. The equipment distills 30%~70% dilute alcohol to 93%~95%, and the purified ethanol is reused for extraction, cleaning, and extract preparation; The equipment material meets the requirements of GMP clean production, and the residual liquid has low alcohol content, reducing the pressure of wastewater treatment.
2. Food industry: Used for the extraction of food raw materials, spice extraction, fruit and vegetable alcohol extraction, and the recovery of dilute alcohol generated from food workshop cleaning. The recovered alcohol can be reused in the food extraction process to ensure product safety.
3. Chemical and light industry: Recovery of waste ethanol solution generated from chemical synthesis, product cleaning, and extraction processes; It can also be used for distillation recovery of low boiling point organic solvents such as methanol and acetone (by changing process parameters), reducing the purchase of new solvents and lowering production costs.
4. Environmental protection and emission reduction: Separate ethanol from waste liquid, significantly reduce COD and alcohol content in discharged wastewater, meet environmental discharge standards, and reduce the amount of hazardous waste disposal.
5. Other supporting scenarios: The extraction and concentration unit can be operated continuously, supporting both intermittent distillation and continuous distillation modes; Some photovoltaic and new material companies also use this equipment to recycle the ethanol waste liquid generated during the cleaning process.
