Embodiment 1

[0042] Embodiment 1 of the present application provides a method such as figure 1 The high-efficiency mobile gas-liquid dual-mode hydrogen fuel filling device shown includes a liquid hydrogen storage and vaporization system and an intelligent control system for the filling process; the liquid hydrogen storage and vaporization system includes a liquid hydrogen storage unit, a hydrogen recovery module and multiple liquid hydrogen Vaporization unit; filling process intelligent control system includes central processing unit, temperature sensor, pressure sensor, automatic control valve, safety relief valve and check valve;

[0043] The liquid hydrogen storage unit includes a main liquid hydrogen tank 1, and the main liquid hydrogen tank 1 is surrounded by an explosion-proof wall enclosure 18; the liquid hydrogen input port 20 at one end of the liquid hydrogen input pipeline 2 is connected to the liquid hydrogen source, and the liquid hydrogen input pipeline 2 The other end is conn...

Embodiment 2

[0047] On the basis of Embodiment 1, Embodiment 2 of this application provides the working method of the high-efficiency mobile gas-liquid dual-mode hydrogen fuel filling device in Embodiment 1:

[0048] The gas-liquid dual-mode hydrogen fuel filling device replenishes liquid hydrogen: the liquid hydrogen input port 20 is connected to the liquid hydrogen source, and the liquid hydrogen directly enters the liquid hydrogen main tank 1, and the pressure sensor 10 and the temperature sensor 11 in the liquid hydrogen main tank 1 are synchronized Detect the pressure and temperature in the liquid hydrogen main tank 1. When the pressure in the liquid hydrogen main tank 1 exceeds the set value due to too much flash hydrogen, the central processing unit issues an instruction to open the outlet connection of the liquid hydrogen self-pressurization pipeline 4. The pressure relief valve 8 in the safety relief valve 8 releases the pressure, and all other valves remain closed; when the liquid...

Abstract

The invention relates to an efficient movable gas-liquid dual-mode hydrogen fuel filling device. The efficient movable gas-liquid dual-mode hydrogen fuel filling device is operated according to the steps that liquid hydrogen is supplemented by the gas-liquid dual-mode hydrogen fuel filling device; the gas-liquid dual-mode hydrogen fuel filling device prepares for filling; and a liquid hydrogen vaporization unit enters an enhanced heat exchange stage, the liquid hydrogen vaporization unit fully exchanges heat with air through metal fins on a liquid hydrogen vaporization cavity, liquid hydrogen in the liquid hydrogen vaporization cavity absorbs heat to be vaporized, the pressure is increased, and after the set filling pressure is reached, filling preparation is completed. The device has the beneficial effects that extra electric energy can be generated and stored in a vehicle-mounted battery; the device can be used for driving truck platforms and in other application occasions, the energy self-sufficiency rate is greatly increased, the economical efficiency of hydrogenation facilities is improved, and the service market and the application range of the hydrogenation facilities are expanded; and low-temperature liquid hydrogen is used as a main hydrogen storage mode, so that the hydrogen storage capacity is improved, a gaseous hydrogen fuel filling mode and a liquid hydrogen fuel filling mode can be provided, and the application scenarios of the filling system are increased.

Description

technical field [0001] The invention belongs to the technical field of hydrogen fuel filling, in particular to an efficient mobile gas-liquid dual-mode hydrogen fuel filling device. Background technique [0002] As a typical clean energy, hydrogen has gradually gained favor from the scientific community, industry and governments due to its high calorific value and non-polluting combustion characteristics. It is an ideal substitute for traditional fossil energy, especially in transportation where fossil energy dominates. field. It is predicted that by 2050, the number of fuel cell vehicles in my country will reach 30 million. The supporting hydrogen fueling infrastructure will usher in huge market opportunities. [0003] At present, the hydrogen refueling facilities for passenger vehicles on the market are mainly fixed hydrogen refueling stations and mobile hydrogen refueling vehicles. Among them, hydrogen fuel is mainly stored in the form of normal temperature gas or cryo...
