Under the current background of high-quality development, manufacturing enterprises are at a critical node of transformation and upgrading. On the one hand, the policy level puts forward higher requirements for energy conservation, emission reduction and clean production; on the other hand, the market’s expectations for product quality, production efficiency and intelligence continue to increase. Driven by this dual drive, enterprises can only stand out in the fierce competition by working hard on “equipment selection” and “technology investment”.
As an important equipment in the field of industrial separation, the horizontal screw centrifuge has been widely used in many industries such as food, chemical, pharmaceutical, environmental protection, petroleum, mining, metallurgy, etc. in recent years. With its continuous, high-efficiency, low-energy consumption and intelligent characteristics, it has become an important equipment to promote the long-term development of enterprises.
Technical principles and performance advantages
Decanter Centrifuge is a device that uses high-speed rotation to generate strong centrifugal force to effectively separate materials of different densities. Its core technology is to achieve continuous and automatic solid-liquid (or solid-liquid-liquid) separation. Without the need for filter materials, the internal and external rotors are controlled by a differential to achieve high-efficiency and high-reliability operation.
Core performance advantages:
Strong continuity
Compared with traditional batch sedimentation or filter press equipment, the decanter centrifuge achieves continuous feeding, separation, slag discharge, and liquid discharge, greatly improving production efficiency.
High degree of automation
The equipment can be integrated with a PLC control system, which can realize remote monitoring, parameter adjustment, abnormal alarm and other functions, reducing human dependence.
Accurate separation effect
The parameters such as drum speed, differential speed, liquid level depth, etc. can be adjusted according to the characteristics of the material to achieve efficient adaptation to materials of different particle sizes, concentrations, and viscosities.
Stable operation and simple maintenance
Compact structure, low vibration, low noise, long maintenance cycle, greatly reducing the risk of unplanned downtime.
Energy saving and environmental protection
The equipment adopts advanced frequency conversion control system with low energy consumption; closed operation avoids material leakage and environmental pollution.
These performance advantages not only reflect the technical advancement of the decanter centrifuge, but also lay the foundation for its long-term value in enterprise operations.
Long-term value analysis at the economic level
1. Save labor and operation and maintenance costs
Traditional separation processes such as sedimentation tanks, filter presses, centrifuge tubes, etc. require a large number of manpower on duty and frequent cleaning, which is labor-intensive. However, the horizontal screw centrifuge has a high degree of automation, and only one person is required to patrol and manage one device, which greatly saves labor costs.
Take a chemical plant as an example: the original 3-worker team rotated day and night to operate the plate and frame filter press system. After switching to the horizontal screw centrifuge, only one person was required to patrol, and the annual labor cost was saved by more than 200,000 yuan.
2. Improve processing efficiency and increase production capacity
The equipment can operate continuously for 24 hours, and the processing capacity of a single device is as high as 3~60m³/h. The mud dryness is high, the liquid phase clarification effect is good, and the process time is greatly shortened.
In the food industry, after a juice factory introduced a horizontal screw centrifuge, the juice yield increased by 8%, the pomace residue decreased by 30%, and the annual output increased by nearly 600 tons.
3. Reduce material loss and improve product yield
By precisely controlling separation parameters, the decanter centrifuge can maximize the recovery of usable substances, such as protein in whey, residual oil in oil, enzymes and bacteria in fermentation broth, and reduce the loss of usable components.
In oil and fat enterprises, the residual oil rate dropped from 6% to 1.5% after the introduction of the decanter centrifuge, and the annual revenue increased by millions of yuan.
4. Extend equipment life and reduce replacement frequency
The core components of the decanter centrifuge are made of corrosion-resistant and wear-resistant materials such as alloy steel, ceramic spraying, and high-strength bearings. The design life of the whole machine is more than 10 years, which is far better than traditional equipment.
Long-term value contribution in environmental protection
The value of the decanter centrifuge in environmental protection is particularly prominent, and it is an important tool for enterprises to achieve green and sustainable development.
1. Reduce the moisture content of sludge, reduce the amount and volume
The treatment cost of high-moisture sludge is high and transportation is difficult. The decanter centrifuge can reduce the moisture content from 90% to about 70%, reduce the sludge volume by nearly half, and save transportation and subsequent treatment costs.
2. Reduce odor and odor emissions
Since the equipment is a closed structure, no open gas diffusion is generated during operation, which effectively avoids odor nuisance and improves the factory environment.
3. Help enterprises achieve environmental compliance and emission standards
For sewage, chemical, and pharmaceutical companies, the decanter centrifuge helps them achieve national or local emission standards, avoid fines, suspension of production, or damage to brand reputation.
4. Convenient for recycling and reuse, helping resource circulation
Such as residual oil recovery in oil residue, waste yeast recovery in breweries, and secondary use of bacterial cells in pharmaceutical factories, it effectively promotes the regeneration and comprehensive utilization of resources, which meets the industry requirements under the background of the “dual carbon” strategy.
Selection suggestions and precautions
To maximize the long-term value of the horizontal screw centrifuge, enterprises should pay attention to the following points when selecting and deploying:
Fully evaluate the properties of the material: solid content, viscosity, particle size, etc. determine the matching of equipment parameters;
Clear production capacity and continuous operation requirements: select appropriate processing volume and operation time;
Focus on follow-up service capabilities: high-quality suppliers should provide installation and commissioning, remote diagnosis, spare parts supply and technical training;
Scalability: consider whether to support future needs such as transformation and modular expansion;
Environmental certification and energy efficiency comparison: products that have passed ISO, CE, RoHS and other environmental and quality system certifications are preferred.
The decanter centrifuge is not only a separation device, but also an important technical asset that promotes enterprises to achieve efficient operation, environmental compliance, and intelligent manufacturing. The “long-term dividends” it brings, such as cost savings, increased production capacity, enhanced environmental protection, and optimized management, are becoming an important choice for more and more industry leaders.
In this era of “long-termism”, equipment investment should not only look at the purchase price, but also evaluate its support for the company’s ten, twenty, or even longer-term development goals. The decanter centrifuge is just such a “long-term value equipment.”
