Description

Technical Field

[0001] The utility model belongs to the technical field of industrial waste water recovery, in particular to a rectification device for ethyl acetate and ethanol used in industrial waste water. Background Art

[0002] Ethanol is a colorless, clear liquid with a burning odor. It flows easily and readily absorbs water from the air. It has a density of 0.789, a melting point of -114.1°C, and a boiling point of 78.5°C. It is an important organic solvent widely used in pharmaceuticals, coatings, sanitary products, cosmetics, oils, and other fields. Ethyl acetate, also known as ethyl acetate, has a density of 0.897, a melting point of -84°C, and a boiling point of 77°C. Pure ethyl acetate is a colorless, transparent liquid with a pungent odor. It has excellent solubility and quick drying properties, making it a versatile organic chemical raw material and an excellent industrial solvent. It is widely used in the production of cellulose acetate, ethyl cellulose, chlorinated rubber, vinyl resin, cellulose acetate resin, synthetic rubber, coatings, and paints. Chemical production generates large amounts of industrial wastewater containing ethyl acetate and ethanol. Therefore, it is necessary to distill the pure ethyl acetate and ethanol in the wastewater and then separate the ethyl acetate and ethanol from the resulting mixture of ethyl acetate, ethanol, and water. However, existing ethyl acetate and ethanol distillation equipment lacks sufficient heating efficiency, reducing treatment efficiency. Utility Model Content
