Embodiment Construction
[0021] Below in conjunction with accompanying drawing, the present invention is described in detail.
[0022] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0023] Such as figure 1 with figure 2 As shown, a safe explosion-proof natural gas storage tank includes a tank body 1, and the tank body 1 is provided with several ring-shaped thin-walled parts-2 integrated with the tank body through cutting processing, and the ring-shaped thin-walled parts-2 Divide the body of the tank into several modules 3, the modules 3 and the annular thin-walled part 1 together form a burst part, and the burst part cracks when the pressure in the tank exceeds a specified...

The invention discloses a safe explosive-handling natural gas storage tank which comprises a tank body; a plurality of first annular thin wall parts are arranged on the whole tank body; the first annular thin wall parts and the tank body are integrated through machining; the first annular thin wall parts divide the whole body of the tank body into a plurality of modules; the modules and the first annular thin wall parts jointly form an explosion part; when pressure in the tank body exceeds a specified value, the explosion part cracks to release the pressure in the tank body outwards, the upper and lower peripheral bodies of the tank body are welded with foamed metal interlayers; and the modules are strengthened and fixed through the foamed metal interlayers. Due to the first annular thin wall parts, when the pressure in the tank body exceeds the designed specified value, the tank body explodes and forms a plurality of metal blocks in specified size, the generation of small-sized metal blocks is reduced substantially, and burst metal blocks can be blocked by buildings around as much as possible, so that injuries to personnel around are reduced effectively, and the injury severity and risk arising from explosion of a natural gas storage tank are reduced.
Description
technical field [0001] The invention relates to the field of petroleum and natural gas storage equipment, in particular to a safe explosion-proof natural gas storage tank. Background technique [0002] The existing natural gas storage tanks have high gas storage pressure and large gas storage capacity, which are major hazards, and their safety issues have attracted much attention. The evaluation of the safety of natural gas storage tanks can be evaluated by risk index evaluation method, such as fire and explosion hazard index evaluation method, Mond method and risk evaluation method, etc. However, the impact analysis on the scope of damage and the main forms of damage caused by natural gas storage tanks is less involved. [0003] When a natural gas storage tank explodes, it usually uses a weak link in the tank as a breakthrough to release energy in a violent burst, and the tank uses the breakthrough as a source of cracking to crack the whole body and separate into multiple ...
