Alcohol recovery tower for the pharmaceutical, food, light industry, chemical industry and other industries dilute alcohol recovery. It is also suitable for the distillation of other soluble coal products such as methanol.Alcohol recovery tower working principle using alcohol having a boiling point lower than than the other the boiling point of the solution of the principle, with slightly higher than the temperature of the boiling point of alcohol, will be recycled dilute alcohol solution were heated volatile, tower body distillation precipitation of pure alcohol gas and improve the concentration of alcohol solution to alcohol recovery.Recovery tower is composed of a tower kettle, a tower body, a condenser, a cooler, a buffer tank, a high position tank six part, applicable to the pharmaceutical, food, light industry, chemical industry industry dilute alcohol recovery, the contact part of the equipment and the material are used stainless steel SUS304 or SUS316L manufacturing, has good corrosion resistance, and has the advantages of energy-saving, environmental protection, reduce production costs, improve efficiency. The device can be 30 degrees to 50 degrees of dilute alcohol distilled to 93 degrees to 95 degrees, residual liquid discharge with low alcohol content, in line with environmental protection requirements.
