For alcohol recovery, the most economical machine is the rotary evaporator, and the most efficient is the rising film evaporator. According to the actual needs of customers, you can also choose a wiped film evaporator and a falling film evaporator. Different alcohol recovery equipment has different advantages, just choose the most suitable one based on your actual needs. Today we will mainly understand together, what is the working principle of alcohol recovery equipment?
The working principle of the alcohol recovery tower is to use the principle that the boiling point of alcohol is lower than that of other solutions. Use a temperature slightly higher than the boiling point of alcohol to heat and volatilize the dilute alcohol solution to be recovered. After the tower body is refined, pure alcohol is precipitated. Gas, increase the concentration of alcohol solution, to achieve the purpose of alcohol recovery.
For rising film evaporator, It is composed of alcohol feeding pump, feeding tank, evaporation tower, separation chamber, condenser, recovery tank, high-precision gear pump or centrifugal pump. Rising film evaporator is suitable for the recovery of dilute alcohol in the pharmaceutical, food, light industry, chemical and other industries. The contact parts between the evaporator and materials are made of stainless steel SUS304 or SUS316L, which has good corrosion resistance, and has the advantages of energy saving, environmental protection, lower production costs, and improved efficiency. This alcohol recovery device can distill the dilute alcohol of 30 to 50 degrees to 93 to 95 degrees, and the residual liquid discharge has low alcohol content, which meets the requirements of environmental protection.
