In today’s context of rapid industrial development and increasingly stringent environmental protection requirements, the importance of solid-liquid separation equipment has become increasingly prominent. Horizontal screw centrifuge (also known as horizontal spiral sedimentation centrifuge), as a modern separation equipment integrating automation, continuity and high efficiency, is playing an irreplaceable role in municipal sewage, industrial wastewater, petrochemicals, food processing, papermaking, pharmaceuticals and other fields.
As a professional Chinese decanter centrifuge manufacturer, we always adhere to the development concept of “technology leadership, quality-oriented, customer first”, focusing on the research and development, manufacturing and service of decanter centrifuges, and providing users with efficient, reliable and customized solid-liquid separation solutions. This article will give you a comprehensive understanding of the technical principles, product advantages, application areas, customer cases, common problems and industry development trends of decanter centrifuges.
What is a decanter centrifuge?
A decanter centrifuge is a continuously working sedimentation centrifugal separation device, mainly used to process solid-liquid mixtures. The device quickly separates materials of different densities through the centrifugal force generated by high-speed rotation, thereby achieving the purpose of liquid clarification, solid concentration or dehydration.
Technical principle
The material is continuously transported into the drum through the feed pipe. Under high-speed rotation, the material is subjected to thousands of times the gravity acceleration, and the solid particles quickly settle to the inner wall of the drum to form a solid phase layer; while the liquid forms a liquid phase layer and is discharged from the other end of the drum. The speed difference between the screw conveyor and the drum is adjusted by the differential to achieve continuous transportation and discharge of solids.
Outstanding advantages of decanter centrifuge
1. Strong continuous operation capability
Decanter centrifuge supports all-weather uninterrupted operation and is suitable for large-scale, continuous production needs, such as municipal sludge dewatering, industrial waste liquid treatment, etc., truly realizing unattended and automatic operation.
2. Efficient separation performance
The separation factor is as high as 2000G-4000G, and the processing speed is fast;
The processing capacity ranges from 1m³/h to 60m³/h, which is suitable for use scenarios of different scales;
When used with flocculants, it can significantly improve the separation efficiency and solid recovery rate.
Widely used in industry scenarios
Decanter centrifuges can be used in almost all fields that require solid-liquid separation. The following are some typical industry applications:
1. Municipal sewage treatment
Dehydration treatment of residual sludge and primary sludge;
Replace traditional belt filter presses to reduce water content and improve incineration or landfill efficiency.
2. Oil and gas industry
Drilling fluid purification, oily sludge treatment, oil-water-solid three-phase separation;
Widely used in shale gas, crude oil mining and other working conditions.
3. Chemical and pharmaceutical industry
Solid-liquid separation of reaction liquid, crystallization liquid, and fermentation liquid;
Efficient treatment of small particles and viscous materials can be achieved.
4. Food and beverage industry
Solid-liquid clarification of soy products, juice, dairy products, and starch;
Protect product flavor while improving production efficiency.
5. Papermaking and dyeing industry
Wastewater treatment, white water recovery, pigment recovery, etc.;
Improve factory drainage indicators and reduce environmental protection costs.
