As the core filter element of turbine regeneration devices, Cellulose filter element for regeneration device A156.73.43.10 is specially designed for turbine oil regeneration (such as dehydration, deacidification, and particle interception). With its environmentally friendly materials, high adsorption performance and long-life characteristics, it has become a key component for oil recycling and low-carbon operation and maintenance in the industrial field. This article will analyze the unique advantages of this filter element from the dimensions of technical highlights, application value and measured data.

Cellulose filter element for regeneration device A156.73.43.10 is mainly used in turbine oil regeneration devices. Its core functions include:

- Deeply adsorb free water and emulsified water to control the water content of oil to ≤100ppm;

- Capture acidic substances (such as carboxylic acids and esters) generated by oxidation to inhibit the increase of oil acid value;

- Intercept solid particles above 5μm to prevent mechanical wear and sludge generation;

- Extend the service life of oil, reduce waste oil emissions, and help achieve the “dual carbon” goals.

Technical highlights

1. Multi-layer composite structure design

The filter element adopts a gradient filtration solution of natural cellulose fiber + resin bonding layer + polyester support layer:

- Outer layer: high-density cellulose fiber, which efficiently absorbs water and polar pollutants through hydrogen bonds;

- Middle layer: cationic resin coating, neutralizes acidic substances and reduces the acid value of oil (acid value inhibition rate ≥ 85%);

- Inner layer: tear-resistant polyester mesh, providing mechanical support to prevent fiber shedding.

2. Environmental protection and safety characteristics

- Biodegradability: Cellulose materials can be naturally degraded and meet ISO 14855 environmental protection standards;

- Fire rating: UL 94 V-0 certified, suitable for high-temperature oil and gas environments;

- No metal precipitation: avoid secondary contamination of oil by traditional metal filter materials.

Application

- Steam turbine lubricating oil regeneration system: connected in series at the rear end of the vacuum dehydration device to deeply remove residual water;

- EH fire-resistant oil purification circuit: adsorb acidic substances produced by phosphate ester degradation, maintaining resistivity ≥5.0×10⁹Ω·cm;

- Oil offline regeneration equipment: cooperate with the centrifuge to achieve rapid recovery of waste oil performance.

Maintenance recommendations

- Condition monitoring: install a differential pressure sensor (threshold 0.25MPa) to prompt replacement in real time;

- Regeneration treatment: waste filter elements can be safely treated by high-temperature incineration (≥600℃);

- Storage conditions: avoid light and moisture, temperature 10-30℃, to avoid moisture and hardening of the cellulose layer.

Cellulose filter element for regeneration device A156.73.43.10 provides a cost-effective pollution control solution for turbine oil systems through the integration of natural material science and oil regeneration technology. Its environmentally friendly properties and excellent adsorption performance not only reduce operation and maintenance costs, but also promote green transformation in the industrial field. It is recommended that users combine oil laboratory analysis data to establish a dynamic replacement model to maximize the regeneration potential of the filter element.
