1Agglomeration separation oil filter is an efficient oil purification equipment, specifically designed to remove free water, emulsified water, and solid particulate pollutants from light fuels such as diesel and kerosene. The core principle is to use two different filter elements, "coalescence" and "separation", to work together to achieve three-phase separation of oil, water, and solid.
2、 Core working principle
Agglomeration process: The contaminated oil first passes through the agglomeration filter element. This filter element is made of special oleophilic and hydrophobic materials, and its function is to:
Capture tiny water droplets: allowing tiny water droplets (including partially emulsified water) passing through the filter material to collide, aggregate, and merge to form larger water droplets.
Capture solid particles: At the same time, the filter also intercepts solid impurities in the fuel.
Then, at the outlet of the coalescing filter, a mixture of "oil+large water droplets" was formed.
Separation process:
The mixed liquid then enters the separation filter element. The surface of the filter element has undergone special oil repellent and hydrophilic treatment, and its function is to:
Blocking water droplets: Due to surface tension, large water droplets cannot pass through the oil repellent barrier of the separation filter and are effectively blocked outside.
Through clean fuel: Only clean fuel without free water can pass through the separation filter smoothly.
The blocked water droplets settle to the bottom of the collection tank due to gravity.
Emissions:
The settled free water is discharged through automatic or manual drainage valves, and clean fuel is output for equipment use.
3、 Main features and advantages of the product
The advantages and characteristics of this type of product can be summarized as follows:
Efficient dehydration:
Advantages: It can remove tiny water droplets with a particle size of less than 1 micron, and its dehydration efficiency and accuracy are much higher than traditional precipitation or centrifugal separation methods. It can effectively treat free water and partially emulsify water, which ordinary filters cannot achieve.
Precision filtration:
Advantages: While dehydrating, it can efficiently filter solid particles (such as rust, dust, gum, etc.) in fuel, with a filtration accuracy of usually 1-3 microns, effectively protecting downstream precision components.
Three phase separation capability:
Advantages: One device can simultaneously solve the three pollutants of "oil, water, and solid", simplifying the fuel purification system and improving treatment efficiency.
Automated operation:
Advantages: The * * model is equipped with an automatic drainage valve and an online moisture sensor, which can achieve unmanned automatic drainage, greatly reducing maintenance workload and management costs.
Extend equipment lifespan and reduce operating costs:
Advantages: Clean and dry fuel can greatly reduce the wear, corrosion, and sticking of precision components such as engine fuel injection pumps and injectors, significantly extending their overhaul cycle and service life, saving huge maintenance costs and downtime losses.
Improve operational efficiency and reliability:
Advantages: Avoiding power drop, black smoke, difficult start-up, and even shutdown faults caused by fuel water content, ensuring the continuity and reliability of power generation or navigation.
4、 The application in the diesel generator industry is very extensive, and it is moving from being "optional"performBecoming“commonly used”
Background and driving force:
Fuel quality issue: The quality of commercially available diesel varies greatly, and it is easy to mix in moisture and impurities during storage and transportation.
Tightening emission regulations: Modern high-pressure common rail engines have high requirements for fuel cleanliness, and even small amounts of moisture and particles can cause system failures and emissions exceeding standards.
The pursuit of reliability: As a backup power source, diesel generators are often started at critical moments (such as power outages, data centers, hospitals), and their reliability is crucial.
Specific application scenarios:
Backup generator sets: data centers, financial centers, hospitals, airports, communication base stations, etc. In these scenarios, the coalescing oil filter is usually used as an online or offline (bypass) purification system, continuously circulating and filtering the fuel in the fuel tank during the standby of the generator set, ensuring that the fuel is always in a "standby" state.
Constant load generator set: mines, remote power stations, construction sites. Fuel consumption is high, storage time is long, and pollution risk is high. The coalescing oil filter can be used as a protective layer before and after the main fuel supply pipeline, or to purify the fuel in the storage tank.
Fuel management services: Professional fuel service companies use mobile coalescing filters to provide customers with tank cleaning and fuel recovery services, with huge market potential.
Summary of Prospects:
With the increasing demand for power generation reliability and the advancement of engine technology, installing a coalescing separation oil filter has become a standard configuration to ensure the efficient and long-lasting operation of generator sets, and its market demand will continue to grow.
5、 Application prospects and specific applications in the shipbuilding industry
Poor environment: During the transportation and storage of ship fuel at sea, due to the large temperature difference between day and night, the condensation phenomenon on the cabin walls is severe, resulting in a very common problem of water accumulation at the bottom of the fuel tank.
Fuel diversity: Ships often use heavy fuel oil (HFO) and inferior diesel, which need to be separated and purified before entering the engine. Even when using light diesel (MGO/MDO), its quality is far inferior to that of land-based diesel.
**Requirement: Moisture in fuel is a breeding ground for microorganisms, and the resulting "sludge" can clog filters and pipelines, causing serious operational and * * problems.
Specific application scenarios:
Final protection before the main engine and generator electronic fuel injection system: Installing a coalescence separation oil filter as a fine filter before the high-pressure fuel pump of the ship's main and auxiliary engines to intercept trace amounts of moisture and particles that may remain after treatment by the oil separator is a key and effective measure to protect expensive electronic fuel injection systems.
Daily management of fuel tanks: As an offline purification unit, it continuously circulates and purifies the fuel in sedimentation tanks and daily tanks to prevent the formation of sludge and the accumulation of water.
Summary of Prospects:
Under the increasingly strict environmental regulations and the trend of precision in ship power systems, coalescence separation technology has become a very important part of modern ship fuel system design, and its application will be popularized from * * ships to ordinary merchant ships.
