How To Solve The Diesel Fuel Oil Pollution

Writer： Kaiqian Oil Purifier Release time：2025-11-03 16:05 Clicks：

   Diesel fuel is the primary power source for industrial production, transportation, and construction machinery. Its quality directly impacts the efficiency, lifespan, safety, and stability of equipment. However, during transportation, storage, and use, diesel fuel is prone to contamination from water, particulates, colloids, and microorganisms, leading to issues such as incomplete combustion, increased fuel consumption, and reduced power output. It can also cause injector blockages, fuel system corrosion, and accelerated engine wear, resulting in high maintenance costs and unexpected downtime. To address the challenges of diesel contamination, the Kaiqian coalescing oil filter employs advanced precision filtration technology, providing a stable and reliable oil purification solution for various diesel-powered applications.

Coalescing Oil Filter in Power Plant

1. Core Technology: Dual-Stage Filtration, Efficient Contaminant Separation

Coalescing Stage: The coalescing oil filter utilizes a dual-stage filtration principle of "coalescing + separation" to achieve deep purification of water and impurities from diesel fuel, achieving a filtration accuracy of <1µm. The special polymer material within the filter element is highly hydrophilic, adsorbing and coalescing tiny water droplets dispersed in the diesel fuel for initial purification.

Separation Stage: Diesel fuel that has undergone initial agglomeration enters the separation filter. The filter, made of hydrophobic material, effectively blocks the passage of coalesced water droplets, allowing only pure diesel to flow freely. This ultimately achieves complete separation of water from diesel fuel while also filtering out any remaining fine impurities.

  The entire process requires no heating or chemical additions; purification is achieved solely through physical separation. This avoids altering the diesel fuel's properties, while also being energy-efficient and environmentally friendly. Its filtration efficiency far exceeds that of traditional oil filtration equipment.

2. Two Core Advantages: Addressing Diesel Fuel Use Pain Points

• Efficient dehydration and impurity removal: The system can quickly remove over 99% of free water, emulsified water, and particles larger than 0.5 microns from diesel fuel, achieving diesel cleanliness of NAS 6 grade or higher, reducing carbon buildup, and lowering equipment failure rates.

• Extended equipment lifespan: Pure diesel reduces wear on critical components such as engines, fuel pumps, and injectors, extending equipment maintenance cycles by over 30% and saving on repair and replacement costs.

• Adaptable to Complex Operating Conditions: The equipment is constructed using high-quality, high-pressure, corrosion-resistant steel. The filter cartridges have strong anti-clogging capabilities and can operate stably within a temperature range of -20°C to 80°C and a pressure range of 0.1 MPa to 1.0 MPa. This ensures long-term, continuous filtration across various applications, from outdoor construction machinery to ship propulsion systems and industrial diesel generator sets.

• Simple operation: The equipment is equipped with automatic liquid level control, pressure alarm, and automatic drainage functions, enabling fully automatic operation upon startup. Operators only need to perform regular inspections of the equipment and replace the filter cartridges, significantly reducing labor costs.

3. Versatile in multiple scenarios:

Transportation: This system provides pre-filtration for the fuel systems of diesel-powered vehicles, including freight trucks, passenger buses, and ships, preventing roadblocks caused by oil contamination, ensuring smooth transportation routes, and minimizing delays and losses.

Construction Machinery: Suitable for outdoor equipment such as excavators, loaders, and rollers, it effectively blocks moisture and impurities from entering the engine in complex environments like dust and rain, ensuring continuous and stable operation during construction and accelerating progress.

Industrial Production: Provides oil purification for diesel generator sets and boiler combustion systems in factories, ensuring a stable emergency power supply and sufficient boiler combustion. This prevents production interruptions caused by power outages, reduces fuel consumption and exhaust emissions, and helps companies achieve green production.

Oil Storage: Used for regular circulation filtration in diesel storage tanks, preventing deterioration caused by moisture accumulation and microbial growth during long-term storage, extending diesel's shelf life, and avoiding economic losses caused by oil scrapping.
