Hydrogen supply system and working method of a vehicle-mounted hydrogen storage cylinder

Abstract

The invention relates to a hydrogen supply system of a vehicle-mounted hydrogen storage bottle and a working method thereof, and belongs to the field of clean and environment-friendly hydrogen energy.The hydrogen supply system comprises a hydrogen source, a vacuum pump, a vehicle-mounted hydrogen storage bottle, a standby storage tank and three compression mechanisms; the hydrogen source is connected to a first ionic liquid compressor; the vacuum pump, a third-stage high-pressure storage tank and the standby storage tank are connected to the vehicle-mounted hydrogen storage bottle, and the vehicle-mounted hydrogen storage bottle is connected to a first-stage high-pressure storage tank; and a first high-pressure separator, a second high-pressure separator and a third high-pressure separator are connected to the hydrogen source through a storage tank. According to the hydrogen supply system of the vehicle-mounted hydrogen storage bottle and the working method thereof, the hydrogen source passes through an ionic liquid compressor, then the hydrogen source is cooled through a cooler, hydrogen and water are separated through high-pressure separators, and the hydrogen is stored in the high-pressure storage tanks and is supplied to the vehicle-mounted hydrogen storage bottle; and after the hydrogen is subjected to three-stage compression, when the third-stage high-pressure storage tank cannot meet the pressure requirement of the vehicle-mounted hydrogen storage bottle, the standby storage tank can be directly started to be used for quickly inflating the vehicle-mounted hydrogen storage bottle.

Description

technical field [0001] The invention provides a hydrogen supply system for a vehicle-mounted hydrogen storage cylinder and a working method thereof, belonging to the field of clean and environment-friendly hydrogen energy. Background technique [0002] Due to the advantages of abundant resources, environmental protection, renewability and large-scale storage, hydrogen energy stands out among many new energy sources and has become a secondary energy source that has attracted much attention in today's society. In the 1990s, countries rushed to start research on new energy vehicles, especially hydrogen vehicles. For the research of hydrogen energy vehicles, the key technology is how to supply hydrogen to the cylinders for use in vehicles, and the hydrogen supply system of the on-board hydrogen storage cylinders can solve this problem. At present, the patents disclosed for the hydrogen supply system of the vehicle-mounted hydrogen storage cylinder are as follows. [0003] Appl...
