Problems solved by technology

Due to the limited pressure capacity of storage tanks, there are fewer applications for storing gas in gaseous form
Especially in the field of long-distance gas transportation, the storage of gas per unit volume is too small, resulting in low efficiency of gas transportation in gaseous form, and it is difficult to replace gas transportation in liquid form

Embodiment Construction

[0032] The present invention is described in detail below in conjunction with accompanying drawing:

[0033] Such as Figure 1 to Figure 5 As shown, the high-pressure gas storage device 100 includes a first cylinder 120 and a second cylinder 110 . The first barrel 120 and the second barrel 110 are preferably cylindrical.

[0034] The first cylinder 120 is provided with a first chamber 121; the first chamber 121 is used for storing gas at a pressure of P1. The second barrel 110 is provided with a second cavity 111 . The first barrel 120 is disposed in the second cavity 111 of the second barrel 110 . There is a gap between the outer wall 112 of the first barrel 120 and the inner wall 122 of the second barrel 110 . The gap between the outer wall 112 of the first cylinder and the inner wall 122 of the second cylinder is used to store gas at a pressure of P2. The P1 is greater than P2. In a preferred example of the present invention, there are multiple first barrels 120 , all...

Abstract

The invention discloses a high-pressure gas storage device which is characterized by comprising a first cylinder and a second cylinder, wherein a first containing cavity is formed in the first cylinder and is used for storing gas with the highest pressure of P1; a second containing cavity is formed in the second cylinder; the first cylinder is arranged in the second containing cavity of the second cylinder; a gap is formed between the outer wall of the first cylinder and the inner wall of the second cylinder and is used for storing gas with the highest pressure of P2; and P1 is higher than P2. According to the invention, the gas with high pressure is stored in the first containing cavity, and gas with secondary high pressure is stored between the first cylinder and the second cylinder. The pressure difference of the gas inside and outside the first cylinder is smaller than or equal to pressure which can be born by the first cylinder, gas support is provided for the first cylinder by utilizing the gas pressure in a cavity of the gap between the first cylinder and the second cylinder, and the pressure difference borne by the first cylinder is reduced, so that the storage pressure inside the first cylinder is enhanced.

Description

technical field [0001] The invention relates to a high-pressure gas storage device. Background technique [0002] Since the current sea transportation of liquefied natural gas is transported at ultra-low temperature (minus 162 degrees), the production of the hull requires special low-temperature resistant steel, and the cost of manufacturing and maintenance is too high. Moreover, at ultra-low temperature, natural gas is easy to gasify due to temperature rise. Changes will bring about a chain reaction with a high risk factor. [0003] When storing high-pressure gas in gaseous form, the pressure that the storage tank can withstand is limited by the material of the storage tank, which is about 20MPa. The lower the pressure, the less gas can be stored per unit volume of storage tank. Due to the limited pressure capacity of storage tanks, there are few applications for storing gas in gaseous form. Especially in the field of long-distance transport of gas, the storage of gas pe...
