Problems solved by technology

The quality of the oil directly affects the safe and economical operation of the equipment, especially for long-term equipment units, due to severe wear of high-pressure steam seals, motor shaft seals, improper sealing gaps or pressure adjustments, causing steam leakage, and condensers Leakage will cause serious water in the oil, turbidity or emulsification of the oil, accelerate the aging of the oil, produce soap, colloid and organic and inorganic acids, reduce the stability and lubricating value of the oil, and at the same time, the water will interact with the additives in the oil On the other hand, due to the entry of pollutants outside the system through the oil seal and various pores, such as sand, dust, rust residue, carbon particles, internal metal wear particles, and oil oxidation products, it will also Reduce oil viscosity, anti-foam, destroy oil film, increase friction, wear equipment parts, and may cause jamming and failure of speed control system, causing local overheating and even stuffy car

The emulsified oil may also be deposited in the pipeline of the speed regulation and circulation system to form sludge, which prevents the smooth flow of the operating oil and cannot achieve good lubrication, speed regulation and cooling. If it is not handled in time, it may cause major accidents and seriously affect the Safe and economical operation of the unit

[0003] At present, the dehydration treatment of emulsified oil in China mainly adopts the method of adding chemical demulsifiers. Although the demulsification treatment of a certain type of oil can be achieved, the addition of demulsifiers changes the organic components of the original oils, making the demulsification after demulsification difficult. The oil reduces its function or completely loses its original function and is reused as fuel oil. It is difficult to realize the regeneration of emulsified oil

The physical methods of demulsification, such as microwave demulsification and ultrasonic demulsification, have better effects on crude oil, but are not ideal for emulsified oil produced in the actual production process.
