In the wine production process, the treatment of wine lees waste liquid is a crucial link. This waste liquid not only contains high concentrations of organic matter, floating matter and some soluble solids, but also its treatment effect directly affects the efficiency and cost of subsequent wastewater treatment, as well as environmental protection. As a highly efficient solid-liquid separation equipment, the horizontal screw centrifuge plays an important role in the treatment of wine lees waste liquid.
Working principle of the decanter centrifuge
The spiral centrifuge uses the centrifugal force generated by the high-speed rotation of the drum to separate the solid particles from the liquid in the county suspension. Under the action of centrifugal force, the solid particles with a larger specific gravity are thrown to the inner wall of the drum to form a solid phase layer; while the liquid with a smaller specific gravity flows out through the pores in the solid phase layer or the filter cloth to form a liquid phase. By adjusting the parameters such as the speed of the drum, the differential and the speed of the screw conveyor, it is possible to effectively separate particles of different particle sizes and specific gravities.
Advantages of Decanter Centrifuge in Treatment of Wine Spent Liquid
1. Efficient separation: The horizontal screw centrifuge has extremely high separation efficiency, which can quickly separate the solid particles from the liquid in the wine lees waste liquid, reduce the floating matter content of the waste liquid, and provide convenience for subsequent wastewater treatment.
2. High degree of automation: Modern decanter centrifuges usually adopt advanced control systems, which can monitor the separation effect in real time and automatically adjust the working parameters to ensure stable operation and efficient separation of the equipment.
3. Strong adaptability: The horizontal screw centrifuge is suitable for treating wine lees waste liquid of different concentrations and properties, and can meet the needs of different production scales.
4. Energy saving and environmental protection: By optimizing the design and operating parameters, the horizontal screw centrifuge can reduce energy consumption and noise, while reducing waste liquid discharge, meeting environmental protection requirements.
Application examples of decanter centrifuge
A large brewing company we serve uses a horizontal screw centrifuge to treat wine lees waste liquid. After centrifugal separation, the content of floating matter in the waste liquid is significantly reduced, providing favorable conditions for subsequent biological treatment. At the same time, the separated solid particles can be reused as organic fertilizer or feed raw materials, realizing the recycling of resources. In addition, the stable operation and efficient separation of the horizontal screw centrifuge also save the company a lot of processing costs and time.
The horizontal screw centrifuge has significant advantages and application value in the treatment of wine lees waste liquid. By rationally selecting the equipment model and operating parameters, efficient and stable treatment of wine lees waste liquid can be achieved, contributing to the sustainable development of brewing enterprises and environmental protection.
