In the wine production process, the treatment of wine lees waste liquid is a crucial link. This waste liquid contains a large amount of solid particles, organic matter and water. If it is not properly treated, it will not only pollute the environment, but also waste the potential resources. Therefore, it is crucial to choose efficient and reliable separation technology for the treatment of wine lees waste liquid. As an advanced solid-liquid separation equipment, the horizontal screw centrifuge has shown its unique advantages in this field.
The working principle of the horizontal screw centrifuge is mainly based on the action of centrifugal force. Inside the equipment, the material enters the cavity between the drum and the screw conveyor through the feed pipe, and is subjected to strong centrifugal force in the high-speed rotating drum. Due to the density difference between the solid phase and the liquid phase, the heavier solid phase particles are thrown to the inner wall of the drum to form a solid phase layer; while the lighter liquid phase is discharged through the pores in the solid phase layer or the filter cloth under the action of centrifugal force. At the same time, the screw conveyor rotates with the drum at a certain differential speed, and continuously pushes the solid phase layer deposited on the inner wall of the drum to the slag discharge port, thereby realizing solid-liquid separation.
In the treatment of wine lees waste liquid, the decanter centrifuge can efficiently separate the solid particles from the liquid in the waste liquid, purify the waste liquid, and recover valuable solid components. Compared with traditional separation methods, the decanter centrifuge has the following significant advantages:
1. High separation efficiency: The decanter centrifuge can achieve rapid separation of a large amount of wine lees waste liquid in a short time, greatly improving production efficiency.
2. High degree of automation: The equipment is equipped with an advanced control system, which can automatically complete the entire process of feeding, separation, slag discharge and cleaning, reducing manual operation and labor intensity.
3. Energy saving and environmental protection: The decanter centrifuge generates less noise and vibration during operation, and can recycle the solid components in the waste liquid, reducing resource waste and environmental pollution.
4. Strong adaptability: The decanter centrifuge can handle wine lees waste liquid of different concentrations and viscosities, and has strong adaptability and flexibility.
In addition, the application of horizontal screw centrifuge in the treatment of wine lees waste liquid also has certain economic benefits. By recovering the solid components in the waste liquid, it can be reused as feed or fertilizer, etc., creating an additional source of income for the company. At the same time, the purified waste liquid can also be used for irrigation, washing and other purposes, further improving the utilization rate of resources.
