Technical Field

The invention relates to a fire-resistant oil (EH oil) or a fire-resistant oil (EH oil) system used fire-resistant oil regeneration filter material, a manufacturing process and a using method thereof.

Background

The fire-resistant oil (EH oil) is a synthetic oil and has the characteristics of flame retardancy, no precipitate, low volatility, good abrasion resistance, good stability, stable physical property and the like. The fire-resistant oil (EH oil) has a high self-ignition point (350 ℃ of the ignition point of common hydraulic oil and 539 ℃ of the ignition point of fire-resistant oil) and can not be combusted even if falling on the surface of a high-temperature pipeline, so the fire-resistant oil (EH oil) is mainly used in high-temperature regulating systems (such as a steam turbine control and regulation system, a nuclear turbine lubricating oil system, a steel mill high-temperature part control system and the like). However, after the fire-resistant oil (EH oil) is operated for a period of time, the oil often has problems of increased particle size, increased acid value, increased moisture, increased chloride ions, decreased resistivity, and the like due to the environment, operation, system, and the like. These changes in the index cause significant damage (corrosion of the regulating parts, jamming, viscosity reduction, etc.) to the fuel regulation system.

The density of the fire-resistant oil is high (generally: 1.11-1.17), and the kinematic viscosity is also higher than that of the lubricating oil (generally 25mm2/s-45mm 2/s). Due to the high density of the fire-resistant oil, pollutants in the pipeline can be suspended on the liquid level and circulate in the system, so that certain parts are blocked and abraded; the excessive granularity can cause the jamming of a servo valve and the aggravation of the abrasion of an oil engine, and the operation safety of the unit is directly influenced. The high acid value can accelerate the hydrolysis of the fire-resistant oil, thereby shortening the service life of the fire-resistant oil and causing the corrosion of system components; the smaller the acid value, the better. The water can not only cause hydrolytic degradation of the fire-resistant oil and increase of acid value, but also cause corrosion of system components and influence the lubricating property of oil; if the system is flooded, chloride ions can corrode components in the system (oil motors, servo valves, pipes, etc.) and can damage the sealing materials; the low resistivity accelerates the deterioration of the oil quality of the fire-resistant oil and shortens the life of the fire-resistant oil. Therefore, the normal index of the fire-resistant oil is ensured, and the key for prolonging the service life of the unit and ensuring the operation safety of the unit is provided.

At present, although the regenerated filter materials such as diatomite, resin, molecular sieve and the like used domestically and internationally can solve the index problems, the regenerated filter materials are unstable, and the effect of the regenerated filter materials is gradually reduced until the regenerated filter materials lose the effect after long-term use.
