In the realm of electrical power systems, mineral oil is extensively used in transformers and other electrical equipment. Over time, this mineral oil degrades due to various factors such as oxidation, moisture ingress, and the presence of contaminants. A mineral oil purifier plays a crucial role in maintaining the quality of mineral oil, ensuring the reliable operation of electrical equipment. In this blog, we'll explore how a mineral oil purifier functions in a mobile application, and as a trusted mineral oil purifier supplier, we'll delve into the technical details and benefits.
The Basics of Mineral Oil Degradation
Mineral oil in transformers serves multiple important functions. It acts as an insulating medium to prevent electrical breakdowns, and it also helps in dissipating heat generated by the transformer's operation. However, during its service life, the oil is exposed to high temperatures, oxygen, and electrical discharges. These conditions cause oxidation, which leads to the formation of acids, sludge, and other polar compounds. Additionally, moisture can enter the oil system through seals or the atmosphere, reducing the oil's dielectric strength. Solid contaminants, such as dust and metal particles, can also find their way into the oil, further degrading its performance.
Working Principle of a Mineral Oil Purifier
A mineral oil purifier typically employs a combination of physical and chemical processes to remove impurities from the oil. The core processes include filtration, dehydration, and degassing.
Filtration
Filtration is the first step in the purification process. The oil passes through a series of filters with different pore sizes. Coarse filters are used initially to remove large solid particles such as rust, dust, and debris. These filters can capture particles as large as several hundred micrometers. Subsequently, fine filters are employed to remove smaller particles, down to a few micrometers in size. The filtration process not only removes visible contaminants but also helps in preventing the accumulation of particles that could otherwise cause abrasion and damage to the internal components of the electrical equipment.
Dehydration
Moisture in mineral oil is a significant concern as it can severely reduce the oil's dielectric strength. Dehydration is achieved through a vacuum dehydration process. The oil is heated to a certain temperature and then introduced into a vacuum chamber. Under vacuum conditions, the boiling point of water is significantly reduced. As a result, the water in the oil evaporates and is removed from the system. The evaporated water is then condensed and collected separately. This process effectively reduces the moisture content in the oil to a very low level, ensuring the oil's insulating properties are restored.
Degassing
In addition to moisture, the oil may also contain dissolved gases such as oxygen, nitrogen, and carbon dioxide. These gases can contribute to oxidation and other chemical reactions in the oil. Degassing is carried out in a similar vacuum chamber as the dehydration process. The vacuum helps to release the dissolved gases from the oil. The released gases are then pumped out of the system, leaving the oil with a lower gas content.
Mobile Application of Mineral Oil Purifiers
In a mobile application, a mineral oil purifier is designed to be portable and easy to operate on-site. Mobile purifiers are equipped with wheels or are mounted on trailers, allowing them to be transported to different locations where electrical equipment is installed. This is especially useful for power utilities, industrial plants, and maintenance teams who need to purify the oil in transformers and other equipment without the need to transport the oil to a fixed purification facility.
The mobile purifier is connected to the electrical equipment through a set of hoses. The oil is pumped out of the equipment and into the purifier. Inside the purifier, the oil undergoes the filtration, dehydration, and degassing processes as described above. After purification, the clean oil is pumped back into the equipment. The entire process can be monitored and controlled through a user-friendly control panel on the mobile purifier. This allows operators to adjust parameters such as temperature, vacuum level, and flow rate to ensure optimal purification results.
Advantages of Using a Mobile Mineral Oil Purifier
- Cost - effectiveness: Instead of replacing the entire volume of degraded oil, purifying the oil on - site can significantly reduce costs. It also eliminates the need for expensive transportation of oil to a central purification facility.
- Time - saving: On - site purification can be carried out quickly, minimizing the downtime of electrical equipment. This is crucial for industries where continuous power supply is essential.
- Environmental friendliness: Reusing purified oil reduces the need for new oil production, which has a positive impact on the environment. It also reduces the disposal of used oil, which can be a challenging and costly process.
