In the production process of petroleum industry, it is an important and challenging task to treat the sludge at the tank bottom. The oil sludge at the tank bottom is composed of oily sludge , water and solid particles. Traditional treatment methods are inefficient and costly, and have potential negative impacts on the environment. However, with the continuous progress of technology, the sludge at the bottom of the tank Three phase separation technology The emergence of the provides a new solution for efficient separation of sludge. This article will introduce the principle of three-phase separation of oil sludge at the tank bottom and the application of ultrasonic technology in Sludge treatment And its importance in improving the efficiency of waste treatment in the petroleum industry.
1、 Principle of three-phase separation of tank bottom sludge
The three-phase separation technology of tank bottom sludge is based on the centrifugal force to effectively separate the oily sludge, water and solid particles in the tank bottom sludge. Its working principle mainly includes the following steps:
1. Feeding: the sludge at the bottom of the tank enters the rotating drum of the three-phase separation equipment through the feeding pipe.
2. Centrifugal separation: through the high-speed rotating drum, the centrifugal force makes the solid particles Centrifuge The water and oily sludge are separated by sedimentation on the wall surface of.
3. Liquid discharge: the separated water and oily sludge are discharged respectively through the discharge pipe at the bottom of the centrifuge to realize three-phase separation of oil sludge at the bottom of the tank.
2、 Application of ultrasonic technology in sludge treatment
As an advanced treatment technology, ultrasonic technology has been widely used in sludge treatment in recent years. Through the function of ultrasonic wave, the following functions can be realized:
1. Improve separation efficiency: ultrasonic has a strong dispersion and depolymerization effect on the solid particles and oily sludge in the tank bottom sludge, thus increasing the separation efficiency.
2. Viscosity reduction: the vibration of ultrasonic wave can effectively reduce the viscosity in the sludge, making the separation process more smooth.
3. Improve waste treatment efficiency: ultrasonic technology can accelerate waste treatment process, reduce treatment time and improve treatment efficiency.
3、 Importance of three-phase separation of oil sludge at tank bottom
The three-phase separation technology of tank bottom sludge is of great significance in the treatment of waste in the petroleum industry:
1. Environmentally friendly: the three-phase separation technology of tank bottom sludge can effectively separate harmful substances in sludge, reduce their impact on the environment and reduce waste discharge.
2. Improve the recovery rate: The oil in the oily sludge can be separated through the three-phase separation technology of tank bottom sludge, so as to improve the recovery rate of oil resources.
3. Cost reduction: The three-phase separation technology of oil sludge at the tank bottom can reduce the cost of manpower, energy and chemicals required by traditional treatment methods, and reduce the overall cost of waste treatment.
As an important technical means of waste treatment in the oil industry, the three-phase separation technology of tank bottom sludge can efficiently treat complex tank bottom sludge, reduce the impact on the environment, and improve the recovery and utilization rate of oil resources. The application of ultrasonic technology in sludge treatment has further improved the separation efficiency and treatment efficiency, providing a new solution for waste treatment in the oil industry. In the future development, continue to research, improve and promote the three-phase separation technology of tank bottom sludge, which will further promote the improvement of waste treatment efficiency in the oil industry and achieve the goal of green and sustainable development.
