Problems solved by technology

[0002] At present, most of the buried oil tanks widely used in domestic gas stations are carbon steel single-layer oil tanks. Due to the electrolytic corrosion in the process of contacting the buried oil tanks with the soil, there are short service life of the oil tanks and pollution after oil leakage. Environmental hidden dangers, the existence of such hidden dangers has caused scientific research scholars to urgently improve the structure of oil tanks to eliminate the above defects

Abstract

The invention relates to an underground double-layered oil tank and a preparation method thereof and provides the underground double-layered oil tank and the preparation method thereof. The underground double-layered oil tank comprises an inner-layer steel tank and a housing, wherein a vacuum interlayer is formed between the inner-layer steel tank and the housing; a detection device for detecting the liquid leakage of the inner-layer steel tank and the housing is arranged in the vacuum interlayer; and the detection device is in remote-communication connection with a control room. The underground double-layered oil tank and the preparation method thereof have the advantages of simple structure, convenience in preparation, low production and maintenance cost, high automation degree, safe and reliable operation, short preparation period and the like, and is conductive to environmental protection.

Description

technical field [0001] The buried oil tank for gas stations of the present invention is especially a buried double-layer oil tank and a preparation method thereof. The buried double-layer oil tank can be used to store gasoline, ethanol gasoline, diesel oil, aviation kerosene, aviation petrol etc. Background technique [0002] At present, the buried oil tanks widely used in domestic gas stations are mostly carbon steel single-layer oil tanks. Due to the electrolytic corrosion in the process of contacting the buried oil tanks with the soil, there are short service life of the oil tanks and pollution after oil leakage. Environmental hidden dangers, the existence of such hidden dangers has caused scientific research scholars to urgently improve the structure of oil tanks to eliminate the above defects. Foreign developed countries (the United States, Japan, the European Union, etc.) started research on double-layer oil tanks earlier, and have a certain share in the market. Howe...
