Explosion-proof device for high-pressure hydrogen tank

Abstract

The invention provides an anti-explosion device for a high-pressure hydrogen tank. The anti-explosion device comprises an underground concrete well wall, well wall prestressed steel wires, unloading springs, a well wall periphery carbon fiber winding layer, a well mouth carbon fiber intercepting net, a high-pressure hydrogen storage tank body, a supporting beam frame and an anti-explosion steel plate, and the well wall prestressed steel wires are poured on the longitudinal well wall of the underground concrete well wall; the unloading springs are connected to the embedded steel plates on the inner side of the underground concrete well wall through bolts respectively. When the high-pressure hydrogen storage tank loses efficacy and explodes, fragments are buffered by a force unloading spring or an anti-explosion steel plate and collide with a well wall to be intercepted by the well wall, and upper fragments are intercepted by a wellhead carbon fiber intercepting net; the anti-explosion steel plate is arranged in a V shape or an I shape and can be vertically or obliquely welded to the well wall embedded steel plate. A plurality of anti-explosion steel plates are arranged, so that the explosion energy can be effectively reduced; by means of the explosion-proof device, even if the high-pressure hydrogen storage tank loses efficacy, huge explosion loss cannot be caused, the hydrogen refueling station can be arranged in the center of a city, and hydrogenation of a hydrogen fuel cell automobile is facilitated.

Description

technical field [0001] The invention belongs to the technical field of hydrogen storage, and in particular relates to an explosion-proof device for high-pressure hydrogen tanks. Background technique [0002] With the excessive development and utilization of traditional fossil energy (oil and coal), its reserves are increasingly depleted, and a series of serious environmental, ecological and social problems have been caused. The development and utilization of new alternative energy is an important measure to solve these problems. Hydrogen, because of its cleanness (the reaction product is only water) and high efficiency, is known as the future energy star. However, the safety of hydrogen utilization has always been one of the main bottlenecks restricting the development of the hydrogen energy industry. The safety of hydrogen storage is the core issue throughout all aspects of hydrogen utilization (including production, storage, transportation and use). Domestic and foreign...

AI Technical Summary

Problems solved by technology

The high-pressure hydrogen storage tanks of current hydrogen refueling stations are all placed above the ground. Once an explosion occurs, it will spread to a range of several hundred meters and cause huge losses. Therefore, the current hydrogen refueling stations are all located in the suburbs of the city, and it is impossible to build hydrogen refueling stations in the city center.
