Safe and covert high-capacity oil depot arranged underground

Abstract

The invention discloses a technical method of a safe and covert high-capacity oil depot arranged underground. The safe and covert high-capacity oil depot arranged underground is characterized in that the oil depot is built in mines to be wasted or abandoned mines or idle tunnels, caves, cave dwellings and culverts. The oil depot is composed of a plurality of nonstandard single storage tanks, wherein the storage tanks are connected through pipelines, and tube valves are mutually communicated and isolated. An oil inlet tube and an oil outlet tube are respectively installed on the upper portion and the lower portion of a tank body and connected with an oil inlet and outlet main tube, the oil inlet tube and the oil outlet tube extend to the ground to be connected with an oil discharge device, and a buffer pump and an oil well pump are installed on the main tube. Inflaming retarding isolation protective screens are arranged among the storage tanks, and a pedestrian path is arranged on the side. Ventilation equipment, fire control equipment, lighting equipment and dewatering equipment are installed in the depot, and a camera shooting monitoring instrument and a gas automatic detecting instrument are installed. The safe and covert high-capacity oil depot arranged underground has functions of fire protection, thunder prevention, war prevention and man-made sabotage prevention, solves the problem that the prior art is large in land occupation, high in construction and operational cost, small in storage content, multiple in environmental factor influence, poor in elusive performance and poor in safety and reliability, and has safety risks on the periphery.

Description

technical field [0001] The invention relates to a large-capacity storage method for crude oil, refined oil and liquefied petroleum gas. Background technique [0002] Petroleum, refined oil, and liquefied petroleum gas are indispensable and important energy sources in modern industry, agriculture, national defense, transportation, and life. They are important strategic materials for all countries in the world. In the long run, with the development of the economy, the demand will increase. bigger and bigger. my country is the second largest oil consumer in the world, and oil reserves are related to national strategic security and stable economic development. Since oil is a non-renewable resource, our country's underground reserves are small. From now on, reducing the exploitation of our country's underground oil and leaving it to future generations is a major long-term strategic measure for our country. From the perspective of the international market, due to various reasons...

AI Technical Summary

Problems solved by technology

[0003] my country's finished oil, crude oil, and liquefied petroleum gas are mostly stored in large single storage tanks on the ground. The problems of this storage method are: (1) It occupies a large area. Due to the safety distance between the storage tank itself and the storage tank Interval requirements require a large amount of land resources

(2) Environmental factors have great influence, are sensitive to environmental factors and climatic conditions, and have many safety hazards, such as high temperature, low temperature, lightning, strong wind, heavy rain, etc. will cause harm

(3) The concealment is poor, the storage tanks and oil depots are built in the open air, and they are easily found to be subjected to military attacks and man-made sabotage

(4) Safety and reliability are poor. During use, it is easy to be harmed by fire, lightning, wind and rain, and earthquakes. It is necessary to take corresponding safety measures such as heat preservation, wind and rain, lightning protection, and earthquake protection. The workload is heavy and the maintenance cost is high.

In particular, once serious accidents such as fires and leaks occur in large-scale storage, it is difficult to extinguish them and directly endanger public safety.

(5) To build a single large-scale oil storage tank, due to the increase in the height of the tank body, the requirements for the foundation, steel performance, and manufacturing process are high, the technology is difficult, the cost increases, and the foundation is prone to uneven subsidence

(6) The capacity of a single storage tank is limited by the pressure bearing capacity of its own materials and the endurance of the foundation, and the height of the storage tank cannot be increased indefinitely. (7) It pollutes the atmosphere and is not conducive to environmental protection.

In short, the currently used oil storage methods, methods and construction and operation costs are greatly restricted
