Description

Treatment equipment for oil-water separation

Technical Field

The utility model relates to the technical field of separation filter tanks, in particular to treatment equipment for oil-water separation.

Background

Tank-in-tank oil-water separation is a common liquid separation technique for separating the two phases of mixed oil and water. It is commonly used in industrial production for treating oily wastewater, oil-water mixtures in petroleum extraction processes, and the like. The in-tank oil-water separation system generally consists of the following components:

1. Tank body: in-tank oil-water separation systems are generally composed of two mutually isolated tanks, an inner tank for collecting the oil phase and an outer tank for collecting the water phase. The inner tank and the outer tank are connected by a water return pipe system, and a valve of the water return pipe system is cut off during normal operation, so that the inner tank and the outer tank are independent. .

2. And (3) a feeding system: for introducing the mixed oil-water two phases into a tank-in-tank system. The feed system typically includes feed piping, valves, and flow control devices to ensure that the proper amount of the oil-water mixture enters the system.

3. Separation device: is used for realizing the separation of oil phase and water phase. Common separation devices include gravity separators, centrifugal separators, filter media, and the like. Gravity separators utilize the difference in density of oil and water to separate them by gravity. Centrifugal separators utilize centrifugal force to separate oil from water. The filter medium is used for separating solid particles and suspended matters from the oil-water mixture through a filter medium such as a filter screen or filter paper.

4. Discharge system: for discharging the separated oil phase and water phase respectively. The drainage system typically includes oil and water phase drainage lines, valves, pumps, and the like.

5. And (3) a control system: for monitoring and controlling the operation of the in-tank oil-water separation system. The control system can automatically control according to the oil-water separation effect, the liquid level and other parameters so as to ensure the stable operation of the system.

The specific design and working principle of the tank-in-tank oil-water separation system can be different according to different application scenes and requirements. In practical application, factors such as oil-water separation efficiency, processing capacity, equipment maintenance and cleaning are also required to be considered so as to ensure efficient operation and long-term stability of the system.

For some practical scenes, the sewage regulating tank is not arranged on site, only a water tank is arranged, and if the pretreatment of oil-water separation is to be realized, the separation of most of floating oil and part of suspended matters in the oily sewage cannot be effectively implemented.
