Dehydration oil filter: key equipment for modern industrial oil treatment

The dehydration oil filter is a new type of oil treatment equipment. It effectively removes water, impurities, particles and tiny bubbles in oil products through a series of advanced physical and chemical methods, and restores the cleanliness and original performance of oil products. This equipment plays an important role in many industries such as electricity, petroleum, chemical industry, metallurgy, papermaking, textile, shipbuilding, etc., especially in occasions with extremely high requirements for oil quality, such as the treatment and recycling of power transformer oil, steam turbine oil, hydraulic oil, lubricating oil, etc., the dehydration oil filter has become an important key equipment.

The working principle of the dehydration oil filter is mainly based on vacuum dehydration technology, precision filtration system and intelligent control system. Vacuum dehydration technology uses vacuum environment to reduce the boiling point of oil products, so that the water dissolved in the oil evaporates and discharges quickly, greatly reducing the water content of oil products, thereby improving the insulation and lubrication properties of oil products. 

The precision filtration system uses high-precision filter materials, such as stainless steel mesh, fiber filter paper or ceramic filter element, to effectively intercept and remove solid particles, colloids and some additive decomposition products in oil products, and improve the cleanliness of oil products. The intelligent control system can accurately control the temperature, pressure and other parameters during the treatment process to ensure the accuracy and efficiency of oil treatment.

In actual application, the working process of the dehydration oil filter includes four process stages: particle filtration, coalescence, sedimentation and separation. 

The oil first enters the coalescence separator after filtering out the particulate pollutants from the primary filter. Under the action of the coalescence filter element, the free water and emulsified water in the oil are coalesced into larger water droplets, and then sink into the water storage tank under the action of gravity. Then, the oil passes through the separation filter element, and the water droplets are blocked on the outer surface of the filter element, coalescing with each other until they sink into the water storage tank due to gravity. Finally, the purified oil is discharged from the outlet to achieve the function of removing water.

The advantages of the dehydration oil filter are not only its efficient dehydration and filtration performance, but also its intelligent operation characteristics. The equipment can realize online operation and automatic control without manual supervision, which greatly improves work efficiency and safety. At the same time, the oil filter also has the advantages of large processing capacity and convenient operation and maintenance, which can meet the needs of different industries for oil treatment.

In the power industry, oil filters are widely used in the purification of transformer oil to keep transformer oil dry and clean, prevent insulation breakdown accidents, and extend the service life of equipment. In the machinery manufacturing industry, oil filters can improve the cleanliness of hydraulic oil, reduce hydraulic system failures, and ensure the continuous and stable operation of the production line. In the petrochemical industry, oil filters can process lubricating oil and base oil, improve oil quality, and reduce production costs. In the shipbuilding industry, oil filters ensure the purity of oil used in ship power systems and improve navigation safety.

In short, the dehydration oil filter, with its excellent dehydration, filtration performance and intelligent operation characteristics, provides strong support for improving oil quality and ensuring stable operation of equipment.
