Large underground fuel gas storage device

Abstract

The invention provides a large underground fuel gas storage device. The large underground fuel gas storage device comprises an oval hollow tank body and sealing covers, wherein three openings are formed in the tank body, including an air injection port, a construction port and an output port, and the sealing covers are arranged on the three openings. The fuel gas storage device is a full-automaticsystem, after gas injection is completed for the first time, unattended operation can be achieved, and when a network cable pipeline stops supplying air or is insufficient in air supply, an electromagnetic switch valve is automatically opened, and air is automatically supplied to the network cable pipeline through a buffer tank; when an external gas source is sufficient, the electromagnetic switch valve is automatically opened, LNG is supplemented into the tank, and the LNG is automatically stopped after being filled. When the fuel gas storage amount needs to be increased, multiple tanks canbe connected in parallel for use. The fuel gas storage device not only can be used for storing the LNG, CNG and other combustible and explosive gas, but also can store combustible and explosive liquidsuch as gasoline and kerosene. The large underground fuel gas storage device plays a positive role in promoting social build-up and improving the living level of urban people.

Description

technical field [0001] The utility model belongs to gas storage equipment, in particular to a large-scale underground gas storage device. Background technique [0002] With the development of society, natural gas has been rapidly developed and widely used as a clean and efficient energy source. People's livelihood-related power generation, chemical raw materials, new energy vehicles, and especially residential gas use have all relied heavily on natural gas. Since my country's reform and opening up, the economy has continued to grow, people's lives have continued to improve, and the pursuit of a good living environment and sustainable development goals has become an important part of the development strategy of building a well-off society in an all-round way. Atmospheric environment and the solemn commitment made by the Chinese government to the world to reduce the emission of CO2 greenhouse gases, vigorously develop and utilize natural gas and other efficient and clean energy...

AI Technical Summary

Problems solved by technology

Because most cities do not have large-scale gas storage equipment, when the external gas supply decreases or the gas supply pipeline fails, or there are problems in the process of transporting LNG, coupled with other factors such as the imbalance of gas consumption day and night, it will directly The gas supply in urban areas fluctuates up and down, and gas supply decreases or cuts off, which seriously affects the production and life of the people.
