Abstract

The invention discloses a modular hydrogen refueling station and a hydrogen sensitive tracer leakage monitoring system thereof. The hydrogen sensitive tracer leakage monitoring system comprises hydrogen sensitive detection adhesive tape, image acquisition devices, a control device and a safe leakage warning device, wherein the hydrogen sensitive detection adhesive tape is wrapped around the jointbetween hydrogen pipelines and the joint between valves and used for detecting hydrogen leakage by color changes; the image acquisition devices are used for shooting the images of the hydrogen sensitive detection adhesive tape and sending the shot images to the control device; the control device is used for judging the color changes of the hydrogen sensitive detection adhesive tape in the images,and when the color of the hydrogen sensitive detection adhesive tape changes, the control device determines that hydrogen leakage occurs and sends a fault signal to the safe leakage warning device; and the safe leakage warning device is in signal connection with the control device and used for giving out a hydrogen leakage alarm signal after receiving the fault signal. The hydrogen sensitive tracer leakage monitoring system can position hydrogen leakage points quickly and accurately and can provide a guarantee for the safety of hydrogen use.

Description

technical field [0001] The invention relates to the technical field of hydrogen leakage detection, in particular to a modular hydrogen refueling station and a hydrogen-sensitive trace leakage monitoring system thereof. Background technique [0002] Hydrogen is a sustainable and environment-friendly green energy, which has the characteristics of wide sources, high combustion calorific value, recyclable utilization, and various storage methods. With the implementation of hydrogen fuel cell projects in various countries, it is bound to rapidly develop supporting infrastructure such as hydrogen refueling stations. As of the end of 2019, there were 432 operating hydrogen refueling stations in the world, of which 330 are open to the public. Over the past 5 years, the number of hydrogen refueling stations open to the public has increased by more than 200%. Hydrogen refueling stations can be divided into fixed hydrogen refueling stations and modular (skid-mounted) hydrogen refueli...
