An automatic oil separation and drainage system for oil tank area

Abstract

The invention relates to the technical field of drainage systems, in particular to an automatic oil separation and water drainage system for a tank farm. The system is composed of a water-sealed well, a drainer and a connecting pipeline. A float valve is arranged in the drainer, the float valve is in an open state when water without oil or with only a small amount of oil exists in the drainer, and the water can be drained out through a water drainage pipe while the oil is stopped to stay on the upper portion of the drainer; when the amount of the stopped oil reaches a set value, the float valve can not float up and is in a closed state, the oil is stored in the drainer in a sealing mode, and therefore the tank farm can be isolated from the outside. By the adoption of the technical scheme, the system has the advantages that the system does not need any energy source and can operate automatically, and therefore automatic oil separation and water drainage are achieved for the tank farm; the water-sealed well arranged in front of the drainer plays a role in initial oil separation and fire prevention, and therefore the safety of the system is improved.

Description

technical field [0001] The invention relates to the technical field of drainage systems, in particular to an automatic oil separation and drainage system for oil tank farms. Background technique [0002] my country is currently the world's largest oil consumer. However, in the process of oil extraction, transportation and storage, due to the leakage, leaking, dripping, and leaking of valves, flanges, and pipelines in the oil tank area, or accidental leakage of oil during maintenance And other reasons, more or less will make the oil into the drainage system. The medium flowing out from the drain is not a single water medium, but a small amount of oil-water mixture, that is, emulsified water, which is prone to fire when exposed to open flames or static electricity, which not only pollutes the environment, but also threatens the lives of people around. In addition, most of the drain valves in the oil tank area are installed outside the fire dike. Although these valves are often...

Problems solved by technology

In addition, most of the drain valves in the oil tank area are installed outside the fire dike. Although these valves are often closed to prevent the outflow of oil products, they must be opened to release water in rainy days. If there is another lightning strike at this time, A fire and explosion occurred in the oil tank, and a large amount of oil in the oil tank leaked into the drainage system. At this time, it is almost impossible for the operator to close the valve, so the area of ​​the fire is expanded, and the heat radiation and smoke generated will cause huge casualties
