specific Embodiment

[0029] The gas source device P2 and each pipeline in the pressurization system can be connected by quick joints, flange bolt structures, etc., through the connecting pipes and fire test bench P3, pressurization and safety release device P4 in the steel plate-concrete composite structure The pipelines in are connected. Connectors can also be used to access signal lines, exhaust pipes, etc.

[0030] The safety isolation device P1 is used to isolate the fire test bench P3 and the pressurization and safety release device P4, so as to avoid secondary damage caused by accidents such as gas cylinder explosion during the test, thereby reducing the test risk and ensuring the safety of the test personnel. In order to protect the building from the damage caused by the explosion shock wave of the gas cylinder, the steel plate-concrete composite structure is used as the main structure, and its inner surface is coated with flame-retardant fireproof paint; the top adopts a floating head, whi...

Abstract

The invention relates to a test technology of a hydrogen storage pressure vessel and aims to provide the local gas cylinder fire test system with a safety isolation device. The local gas cylinder fire test system comprises the safety isolation device composed of a circular floatable sealing head and a cylindrical steel plate-concrete composite structure; a to-be-measured gas cylinder and a fire test bench are arranged inside the safety isolation device; the fire test bench comprises a bearing frame on an upper layer and a tube box on a bottom layer; quartz fiber cloth is paved between the bearing frame and the tube box; two fuel supply pipes with spray nozzles and a diffusion nozzle taking the quartz fiber cloth as gas fuel are formed in the tube box; combustion areas of the spray nozzles in the two fuel supply pipes are respectively corresponding to a local combustion area and an overall combustion area. The local gas cylinder fire test system provided by the invention has the benefits that the test safety is fully guaranteed, and local fire test and overall fire test can be performed; the remote operations of burner ignition, flame height adjustment, extinguishment, thermocouple data acquisition, video monitoring transmission and the like are realized.

Description

technical field [0001] The invention relates to a hydrogen storage pressure vessel testing technology, in particular to a gas cylinder partial fire test system with a safety isolation device, which is mainly used for high-pressure hydrogen storage cylinders for fuel cell electric vehicles. Background technique [0002] As a clean and efficient secondary energy source, hydrogen energy is an important part of the national energy strategy, and hydrogen fuel cells are one of the important ways to use hydrogen energy safely and efficiently. Since 2015, the world's largest automobile companies such as Toyota and Honda have successively launched hydrogen fuel cell vehicle products, and all use carbon fiber-wound composite material high-pressure gas cylinders to store hydrogen as an energy source. Since hydrogen is flammable and explosive, has high combustion calorific value, large explosion energy, and the hydrogen storage pressure of high-pressure hydrogen storage cylinders is as ...
