The multifunctional alcohol recovery tower plays an important role in many industrial fields due to its efficient working performance and many advantages. It not only helps enterprises achieve optimized resource utilization, but also actively responds to the development call of energy conservation and environmental protection. In the future, it will continue to inject stronger power into industrial production with continuous technological innovation.
The basic working principle of a multifunctional alcohol recovery tower:
1. Evaporation section: Dilute alcohol solution (concentration 30-50) is heated in the tower kettle to slightly above the boiling point of alcohol (about 78.4 ℃), and alcohol preferentially vaporizes to form vapor rising.
2. Distillation section: The vapor in the tower body packing layer comes into countercurrent contact with the descending condensate, achieving alcohol purification through mass and heat transfer processes.
3. Recycling section: After passing through multi-stage trays or packing layers, high-purity alcohol vapor enters the condenser for liquefaction and is collected as finished products. The non-volatile impurities and moisture are discharged from the bottom of the tower, and the residual liquid has a low alcohol content, which meets environmental protection requirements.
4. Easy to maintain: The tower kettle adopts a detachable U-shaped tube design, which facilitates regular cleaning and maintenance, reducing downtime.
5. Wide applicability: Suitable for industries such as pharmaceuticals, food, and chemicals, especially for scenarios that require the reuse of alcohol, such as the treatment of mother liquor in traditional Chinese medicine extraction processes.
Precautions for using a multifunctional alcohol recovery tower:
-Safe operation: This tower is a non pressure vessel. If the pressure inside the distillation kettle exceeds 0.03MPA, the steam valve must be immediately closed to identify the cause before continuing to work; Smoking or working with open flames around the tower is strictly prohibited; During the use of the alcohol recovery tower, it is not allowed to leave the site for a long time and 24-hour monitoring should be implemented.
-Material testing: The added solution needs to be tested multiple times to avoid the presence of multiple materials with different properties at the same time, which may cause unnecessary problems in subsequent work.
-Cleaning and maintenance: Before each cleaning operation is completed, it is necessary to ensure that all the alcohol solution in the recovery tower flows out and close the drain outlet to avoid polluting the environment; Regularly clean and maintain the equipment. If there is a significant increase in heating steam pressure, it indicates that scale has formed inside the heat exchange tube, affecting heat transfer. In this case, the heater should be shut down and the top cover should be opened. Use a round steel brush to remove the scale from the heating tube.
-Handover inspection: During the handover, pay attention to whether the valve switches and instrument indications are normal, and strictly prevent water shortage.
