Local gas cylinder fire test system with safety isolation device

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 ...

Problems solved by technology

[0005] Chinese patent CA201410150729.7 provides a gas cylinder fire test test system, but it is mainly aimed at the overall fire test, and cannot meet the requirements for accurate and controllable heating of local gas cylinders in the local fire test, and because the test operation is carried out outdoors, Data measurement is greatly affected by environmental factors such as temperature and wind speed, and the data reliability is poor

In addition, nowadays in China, simple steel frames are often built outdoors and simple isolation panels are set up for testing, which is prone to accidents of gas cylinder explosion and splashing, which poses a large safety hazard
