Residual mist treatment in the application of oil mist lubrication systems

Thread Content

As oil mist lubrication is increasingly used in petrochemical enterprises, its advantages are becoming more apparent, but the negative effects it causes cannot be ignored, especially environmental pollution. Since oil mist lubrication relies on compressed air to atomize the lubricating oil for lubrication, about 20% of the lubricating oil is discharged directly into the external air through the exhaust port, thus causing some pollution to the environment. Therefore, the control and recovery of residual mist are of great significance for the development of oil mist lubrication. To address the environmental pollution issue caused by oil mist lubrication, Shenyang Jiayi Oil Mist Technology Co., Ltd. has developed equipment for recovering residual mist, enabling an environmentally friendly closed-loop control of oil mist lubrication systems. This helps to improve the environment and achieve green and low-carbon production. Working principle: The residual mist recovery unit is designed based on the principles of centrifugal impact and self-circulation. Driven by the motor, the hub rotates at high speed, drawing in oil mist particles into the hub; these particles collide continuously with the blades and coalesce into oil droplets. Under the effect of centrifugal force, these oil droplets pass through the pores in the fiber filter and move toward the inner wall of the housing, where they form larger oil drops that eventually flow back into the oil tank ； The gas rises, passes through the sound-dampening filter pad at the top; part of it is released into the air, while the other part returns to inside the hub for secondary centrifugal impact separation. The oil mist concentration emitted by the residual mist recovery system is ≤ 5 mg/m3, meeting the requirements of OSHA’s Occupational Safety and Health Standards in the United States.
