In the context of today’s rapid industrial development, solid-liquid separation is an indispensable key process in many industries. Its efficiency and reliability directly affect the company’s operating costs, product quality and even environmental protection compliance. Among many separation equipment, the decanter centrifuge has become the preferred equipment in the fields of municipal sewage treatment, chemical industry, food, pharmaceuticals, petroleum, environmental protection, etc. due to its significant advantages such as automation, continuous operation, high efficiency and low energy consumption. Helping users better realize the core value of modern industrial production.
What is a horizontal screw centrifuge?
The horizontal screw centrifuge, also known as the horizontal screw discharge sedimentation centrifuge, is a highly efficient solid-liquid continuous separation device. The internal structure of the device mainly includes a high-speed rotating horizontal drum and a screw conveyor that rotates at a differential speed with it. After the material enters the drum, it is rapidly settled and separated under the action of centrifugal force. The solid matter is pushed to the slag outlet by the screw conveyor and the clarified liquid flows out from the other end. The whole process is completed automatically and continuously.
Working principle: Strong centrifugal force brings efficient separation
1. Introduction to core components
Drum: High-speed rotation generates strong centrifugal force, which is the core area for achieving solid-liquid separation;
Screw conveyor: Rotates relative to the drum at a certain differential speed to push the settled solids to the slag outlet;
Differential: Regulates the speed difference between the drum and the screw to control the slag discharge efficiency;
Feeding system: Stable feeding is achieved through the buffer chamber to avoid disturbing the separation area;
Slag outlet and overflow port: Realize the separate discharge of solids and liquids;
Drive system: Main motor + auxiliary motor provides power, supporting variable frequency speed regulation.
2. Description of separation process
Material enters the drum through the feed port;
Under the action of centrifugal force, solid particles quickly settle to the drum wall;
Screw conveyor pushes out the solids continuously;
Clear liquid is discharged through the overflow pipe.
The entire process can be operated 24 hours a day, truly realizing the modern industrial separation mode of “saving time, saving people, and saving effort”.
Core advantages of decanter centrifuge
1. High efficiency and low energy consumption
Decanter centrifuge can achieve efficient separation in a short time, adapt to high solid content and high viscosity materials, and the processing capacity of a single device can reach more than 100m³/h, while the energy consumption is much lower than that of traditional filter press equipment.
2. Automatic operation, saving labor
The equipment can integrate PLC control system, support one-button start, automatic speed regulation, abnormal alarm and other functions, and realize true unattended operation, especially suitable for areas with high labor costs or continuous operation requirements at night.
3. Compact structure and convenient maintenance
The whole machine occupies a small area, flexible installation, and modular design of the equipment, easy maintenance and replacement of parts, reducing operation and management costs.
4. Strong adaptability and wide application range
It can be used to process materials with various complex working conditions such as high corrosion, high temperature, and high viscosity. The equipment material can be customized according to industry needs (such as 304/316 stainless steel, duplex steel, Hastelloy, etc.).
5. Environmental protection meets standards and helps achieve the “dual carbon” goals
Through effective dehydration, the volume of sludge is greatly reduced, transportation costs are reduced, and pollutant emissions in wastewater are reduced, helping companies meet environmental protection requirements and carbon emission indicators.
FAQ
Q1: What materials are suitable for horizontal screw centrifuges?
A: Almost all suspensions containing settleable solids can be used, such as municipal sludge, fruit and vegetable residues, chemical waste liquid, petroleum sludge, yeast liquid, Chinese medicine residue, etc.
Q2: How low can the moisture content of mud cake be reduced?
A: Depending on the material type and equipment configuration, the moisture content can generally be controlled between 60% and 80%. It can be reduced to below 55% under special design.
Q3: Can it handle highly corrosive materials?
A: Anti-corrosion materials (such as duplex stainless steel, titanium alloy) and explosion-proof electronic control systems can be customized to meet the needs of chemical, pharmaceutical and other industries.
