Product technical principle:

This product is designed specifically for filtering and purifying diesel. Based on the characteristics of light diesel, it uses Dingneng high-performance membrane filtration technology to filter and refine diesel.

The filtering principle is:After the emulsified oil is effectively filtered for impurities and particles through the front-end filter, it is sent to the dehydration filter. The aggregation material in the filtering component aggregates the small water droplets dispersed in the oil into larger water droplets. The aggregated water droplets settle into the lower water tank under the action of gravity and the impact force of the oil flow direction, and are released by the drain valve. Then, the oleophilic and hydrophobic properties of the membrane separation filter material are used to allow the oil to pass smoothly while effectively preventing water droplets from passing through, achieving an effective dehydration effect. By utilizing the selective characteristics of membrane technology, impurities and moisture in diesel can be separated and filtered.

The selective passage of the filter element is to allow oil molecules to pass smoothly while intercepting water molecules and impurities, thereby separating oil and water, filtering out impurity particles, gum, and moisture in diesel, improving the cleanliness and quality level of diesel fuel, and enhancing the performance of diesel fuel.

The membrane filter has a rigid structure, high pressure resistance, and a membrane wall thickness of 3-16mm, which belongs to deep filtration. The pores in the membrane are three-dimensional in structure, and the pore accuracy can be controlled within (30 μ m~0.2 μ m). It can effectively backwash and restore blocked pores. The filter can be reused. Due to the characteristics of the filter membrane, the normal working pressure of the equipment is only 0.2-0.3Map, and low pressure difference, high flow rate, and high production capacity are the significant features of this machine.

Oil water separation:

The filter adopts Dingneng's unique "polymer film separation" technology, which has a particularly significant separation effect on severely emulsified oil containing a large amount of water, and its dehydration efficiency is several times that of ordinary filters.

Filter material:

Diesel specific membrane filter element is the core of Dingneng diesel filtration technology, and the filter element component is made of polymer membrane material; With the excellent characteristics of Dingneng filter membrane material, its service life is more than ten times that of ordinary filter cartridges, or even longer.

The filter membrane does not require frequent replacement, providing customers with higher economy and cost-effectiveness.

Under normal use, the membrane filter can last for 2-3 years or longer. If the oil is particularly dirty, its service life may be shortened. Regular cleaning, maintenance, and upkeep of the membrane filter can greatly improve its service life.

Filter installation and connection:

Fix the filter foot to the ground with expansion bolts, install the filter in series on the pipeline, leave a certain space around the filter, and ensure that the working environment is safe and free of open flame hazards when using this product.

Filtering cost:

Due to the long service life, high cost-effectiveness, small footprint of filtration equipment, low power consumption, filtration pressure difference not exceeding 0.2-0.3MPa, simple operation, low comprehensive energy consumption, material consumption, labor cost and maintenance cost, the total cost is quite low.

Anti cleaning device for filter membrane:

This filter is designed with a backwash system. When the oil filtration system becomes clogged, the pressure will rise, and the backwash system can automatically flush impurities from the filter membrane tube wall.

There is a backwash interface left on the upper part of the filter. When the backwash effect is not ideal, compressed air needs to be used for backwashing to remove impurities from the filter membrane. Since the filter membrane is rigid, backwashing can blow impurities off the wall of the filter membrane tube, and at the same time, most of the particles inside the capillary pores can be backwashed out to achieve regeneration of the fine pores.

When thorough cleaning is required, the quick opening top cover can be opened to thoroughly clean the backwash filter membrane. The current filtration technology cannot make the filter maintenance free forever. Our innovation in technical details can only extend the service life of the filter membrane. It is necessary to regularly drain impurities and moisture from the bottom of the tank and clean the filter membrane.

Attachment: User knowledge:

1. Application

The Dingneng D series filters are commonly used in industries such as oil loading filtration, oil unloading filtration, mining, construction, large generator sets, engineering machinery, refineries, oil depots, docks, railway locomotive refueling stations, military, power, oil extraction plants, etc. The demand and application of diesel filtration by central and Chinese enterprises in Africa, the Middle East, and other regions.

Example 1: Dingneng D series diesel purification filters are widely used in the mining industry and construction machinery. Clean diesel significantly reduces engine failure rates, improves efficiency, reduces maintenance costs, reduces fuel consumption by 5-10%, and has a significant fuel saving effect. The service life of diesel engines is extended by 2-3 times.

Example 2: Application of Dingneng D series diesel purification filter in diesel refining process. As a terminal refining filter, it is very suitable for small refineries to refine and filter diesel, improve diesel cleanliness and grade.

2. Why does diesel need to be filtered

90% of diesel engine malfunctions are caused by dirt and water in the diesel fuel. It is necessary to filter out pollutants and moisture to reduce the cleanliness of oil products. Clean diesel significantly reduces engine failure rates, improves efficiency, reduces maintenance costs, reduces fuel consumption by 5-10%, and has a significant fuel saving effect. The service life of diesel engines is extended by 2-3 times.

3. Regarding diesel:

The quality and cleanliness of diesel fuel are key factors in ensuring engine performance and service life. According to a research report by diesel engine manufacturers, 90% of diesel engine failures are caused by dirt and water in the diesel fuel. Although diesel leaving the refinery is usually clean and up to standard, the oil may be contaminated after multiple storage and transportation, and the cleanliness of the oil may decrease. It is necessary to filter out these pollutants and moisture to reduce the cleanliness of the oil. Polluted diesel can increase engine fuel consumption by 5% -20%, or even higher. For China, diesel pollution is even more serious. Based on the current cleanliness of diesel in our country, "the national requirements for National III and IV engines cannot work properly. In addition, all foreign engines currently in use have lowered their usage standards to meet the relatively dirty diesel in our country, resulting in significant differences in exhaust emissions and fuel consumption compared to similar foreign engines. In China, diesel powered trucks account for only about a quarter of the total number of vehicles, but their emissions of particulate matter account for nearly 80%, making them a major contributor to automobile exhaust pollution. Using clean diesel can greatly reduce the exhaust emissions of diesel vehicles and extend the service life of engines.

4. Decolorization

This model of product is not suitable for diesel decolorization. When using this product in refineries, the color of diesel will become slightly lighter. This is because the transparency of diesel increases after filtering out impurities, and it cannot completely remove the pigments in diesel. To achieve complete decolorization, please choose other methods.

5. Remove odor

This model of filter cannot remove odors from diesel. It is recommended to use other professional methods to remove odors, such as chemical methods, adsorption, etc.

6. Refining process

This model of product cannot be used in the intermediate process of some small refineries, and can only be used as a terminal filtration equipment for diesel to refine the diesel to be shipped.
