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.
