About the Decanter Centrifugal Dewatering System
The Decanter Centrifugal Dewatering System is a highly efficient solid-liquid separation equipment, and its core component is the horizontal spiral unloading sedimentation centrifuge (hereinafter referred to as the decanter centrifuge). The system is widely used in the sludge treatment process in various fields such as urban domestic sludge, papermaking sludge, chemical sludge, pharmaceutical sludge, printing and dyeing sludge, and food industry sludge. The following is a detailed introduction to the decanter centrifugal dewatering system:
Equipment Introduction
The decanter centrifuge is a key equipment in the sludge dewatering system. It uses the principle of centrifugal sedimentation to separate county floating objects. For various county floating liquids with an equivalent diameter of solid particles of 23um, a weight concentration ratio of ≤10% or a volume concentration ratio of ≤70%, and a liquid-solid density difference of 20.05g/cm, the decanter centrifuge can effectively separate liquid and solid. The equipment has a variety of models and can be widely adapted to different separation requirements in different industries.
Working Principle
The main structure of the decanter centrifugal dewatering machine includes a screw shaft, a spiral blade, a differential, a feed port, a washing port, a discharge port, a mud collecting tank, and a drive device. Its working principle is: the centrifugal force is generated by the rotation of the spiral shaft, so that the sludge is separated into liquid and solid parts under the action of centrifugal force. The wave body is discharged through the discharge port, and the solid is collected in the sludge collecting tank. At the same time, under the action of the washing port, washing liquid can be added to wash the sludge to further improve the dehydration effect.
Application fields
The application fields of the decanter centrifugal dehydration system are very wide, mainly including:
1. Chemical industry: used for solid-liquid separation, concentration and dehydration of suspensions, such as separation of solid particles in county suspensions in chemical processes, removal of impurities in waste liquids, and concentration of solutions such as hydrochloric acid, nitric acid, and sulfuric acid.
2. Environmental protection industry: widely used in the treatment of industrial wastewater and urban sludge. Centrifugal separation effectively reduces the solid content in sewage, improves water quality, and achieves waste liquid reduction and resource recycling.
3. Food industry: used for solid-liquid separation and clarification of juice, dairy products, and alcohol, such as juice concentration, soy milk separation, and wine clarification.
4. Pharmaceutical industry: used for the separation and purification process of biological drugs, such as separation of cell culture fluid, extraction of antibiotics, separation of plasma, etc.
In addition, the decanter centrifugal dehydration system is also used in the fields of petroleum, light industry, and non-metallic mineral industry.
