Description

Technical Field

[0001] The utility model relates to the technical field of natural gas storage tanks, in particular to a natural gas explosion-proof storage tank. Background Art

[0002] Natural gas refers to a mixture of hydrocarbons and non-hydrocarbon gases naturally stored in strata. In petroleum geology, it usually refers to oilfield gas and gasfield gas. It mainly exists in oil fields and natural gas fields, and a small amount is also found in coal seams. The main use of natural gas is as fuel. It can be used to make carbon black, chemicals and liquefied petroleum gas. Propane and butane produced from natural gas are important raw materials for modern industry. When people use natural gas, they need to store it in storage tanks and then use it on the move.

[0003] However, when the existing natural gas storage tanks are moved, the liquefied natural gas inside will shake violently. The shaking liquefied natural gas will affect the pressure inside the storage tank, which may easily cause the storage tank to burst. In the past, natural gas storage tanks would also burst after being hit violently, which may easily cause unnecessary harm to people. Therefore, there is an urgent need to solve this problem.

[0025] The pressure relief mechanism includes a pressure relief shell 5 fixed to the top of the natural gas storage tank 1, with slide rails 16 fixed at both ends of the inner wall of the pressure relief shell 5, and a sliding block 17 adapted thereto is slidably provided on the outer wall of the sliding rail 16, and a same connecting plate 18 is fixed to the side where the two sliding blocks 17 are close to each other, a connecting column 19 is fixed to the top of the connecting plate 18, and a sealing plug 15 is fixed to the top of the connecting column 19, an exhaust hole is opened on one side of the top of the pressure relief shell 5, and the sealing plug 15 is adapted to the exhaust hole, and a top rod 13 is provided at the bottom of the connecting plate 18, and when the floating plate 10 rises to contact the bottom of the fixed block 14, the exhaust port will relieve the pressure and exhaust the inside of the natural gas storage tank 1.

[0026] In this embodiment, the top rod 13 passes through the top of the natural gas storage tank 1 and is located inside the natural gas storage tank 1. A fixing block 14 is fixed to the bottom of the top rod 13. A pressure gauge 6 is provided at one end of the top of the natural gas storage tank 1. The bottom of the pressure gauge 6 is connected to a first pressure pipe 7, and the first pressure pipe 7 is communicated with the interior of the natural gas storage tank 1.

[0027] In this embodiment, a second air pressure pipe 12 is provided at the bottom of one end of the pressure relief shell 5 away from the connecting plate 18 , and the second air pressure pipe 12 is communicated with the interior of the natural gas storage tank 1 , and a lifting mechanism is provided below the top rod 13 .

[0028] In this embodiment, the lifting mechanism includes a slide bar 9 fixed to the top of the inner wall of the natural gas storage tank 1, and a floating plate 10 is slidably provided at the bottom of the outer wall of the slide bar 9.

[0029] In this embodiment, a plurality of communicating air holes 11 are formed on the top of the floating plate 10 .

[0030] In this embodiment, a mounting shell is provided on the inner wall of the natural gas storage tank 1, and foam water 8 is provided inside the mounting shell.

[0031] In this embodiment, a protective base 2 is installed at the bottom of the natural gas storage tank 1 , universal wheels 3 are installed at the four corners of the bottom of the protective base 2 , and a protective shell 4 is installed on the outer wall of the natural gas storage tank 1 .

[0032] Working principle: When in use, first install the protective base 2 on the bottom of the natural gas storage tank 1, and then install the protective shell 4 on the outer wall of the natural gas storage tank 1. When the natural gas storage tank 1 is hit and the outer wall is broken, there is a risk of explosion. At this time, the installation shell inside the natural gas storage tank 1 will be broken. When the installation shell is broken, the foam water 8 inside the installation shell will flow out of the installation shell. When the foam water 8 flows out, the foam water 8 will flow from the air vent 11 to the bottom of the floating plate 10. At this time, the foam water 8 will lift the floating plate 10, and the floating plate 10 will move up along the slide bar 9, thereby achieving a certain degree of prevention of explosion-proof of the natural gas storage tank 1. As a result, when the floating plate 10 rises to contact the bottom of the fixed block 14, the floating plate 10 will lift the top rod 13. When the top rod 13 moves up, the top rod 13 will drive the connecting plate 18 to move up. At this time, the connecting plate 18 will drive the two sliders 17 to slide on the slide rail 16. At this time, the connecting plate 18 will drive the connecting column 19 to rise. At this time, the connecting column 19 will drive the sealing plug 15 to rise. At this time, the exhaust port on the top of the pressure relief shell 5 will be opened. At this time, the second air pressure pipe 12 will transport natural gas to the inside of the pressure relief shell 5. At this time, the exhaust port will relieve pressure and exhaust the inside of the natural gas storage tank 1, thereby achieving the explosion-proof effect of the natural gas storage tank 1.
