Embodiment Construction

[0012] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0013] like figure 1 As shown, nine microbead releasers 2 are installed at the bottom of the storage tank 1 . When the crude oil is injected into the tank body 1 for a certain period of time, an oil-water interface 4 will gradually be formed. When the microbead releaser 2 receives the order, it releases the ceramic microbeads 3 stored in it, and when the microbeads 3 slowly rise to the oil-water interface 4 in the water layer 5, they encounter crude oil 6 with a higher viscosity, It will float up very slowly or even stop, thus forming a dense heat insulation layer at the interface of oil and water.

[0014] The crude oil tank 1 is a steel tank for storing crude oil, and its volume is generally 100,000m 3 .

[0015] The microbe...

Abstract

The invention discloses a device capable of preventing the phenomenon that deflagration happens to a crude oil storage tank due to accidental burning of fuel oil when flame burns to the oil-water separation interface. The oil-water separation device comprises a storage tank, ceramic microbeads and microbead releasers. The microbead releasers are installed at the bottom of a storage tank body. The ceramic microbeads are stored in the microbead releasers. As for a conventional crude oil storage tank, a certain amount of moisture always exists in crude oil, and the specific gravity of water is greater than that of the crude oil, so that the water always gathers at the bottom of the tank body to form the oil-water separation interface. According to the oil-water separation device, the microbead releasers are installed at the bottom of the crude oil storage tank, and the ceramic microbeads can be released outwards automatically or manually in emergencies. The ceramic microbeads are of a hollow structure, low in density, and capable of arriving at the oil-water separation interface from the bottom of the tank body rapidly to form a compact heat-insulating layer. A certain heat-insulating and inflaming-retarding effect is achieved through the hollow structure, and thus the phenomenon that deflagration occurs when the flame reaches the oil-water separation interface can be prevented, and spreading of fire is retarded and reduced. The protection effect on the whole tank body is achieved, and a certain protection effect is provided for rescue workers.

Description

technical field [0001] The invention relates to the fields of basic materials and mechanics, in particular to an oil-water separation device for preventing deflagration of crude oil storage tanks. Background technique [0002] In the process of crude oil extraction, some water is often mixed, and due to the large difference in density between crude oil and water, stratification is easy to occur, and a water layer of considerable thickness is often formed at the bottom of the storage tank. When a fire occurs in a storage tank, the crude oil will be gradually burned, especially when the combustion interface reaches the oil-water separation interface, a large amount of heat will be transferred to the water, and the temperature will rise rapidly. When the temperature rises and the water temperature reaches close to the boiling point, a large amount of water vapor will be produced, which will be mixed into the flame, further strengthening the fire, and finally deflagration will o...
