Embodiment Construction

[0032] Embodiment 1 of the hydrogenation machine of the present invention is as figure 1 As shown, it includes a hydrogen storage tank and a hydrogenation gun 17, and also includes a control system 19 that controls the hydrogenation rate according to the ratio of the pressure of the vehicle hydrogen bottle to the temperature change value within the set time. Different high-pressure hydrogen storage tanks 21, medium-pressure hydrogen storage tanks 22, and low-pressure hydrogen storage tanks 23 are connected through a pipeline system between the hydrogen storage tanks and the hydrogenation gun 17. The pipeline system includes a high-pressure hydrogen storage tank 21, a medium-pressure hydrogen storage tank The pressure hydrogen storage tank 22 and the low-pressure hydrogen storage tank 23 respectively lead to the shunt pipeline of the confluence point and the main pipeline connected to the hydrogenation gun 17 from the confluence point. The high-pressure hydrogen storage tank 21 ...

Abstract

The invention relates to a hydrogenation rate control method and a hydrogenation machine. The hydrogenation rate control method comprises the following steps that a control system of the hydrogenationmachine analyzes and calculates the ratio of the change value of the pressure intensity to the change value of the the temperature of a hydrogen cylinder of a vehicle within a set time and compares the ratio with the rated value set in the control system, when delta P/delta T is less than n, the filling rate of hydrogen is decreased, and when delta P/delta T is greater than m, the filling rate ofthe hydrogen is increased, so that delta P/delta T is greater than or equal to n and less than or equal to m. According to the hydrogenation rate control method and the hydrogenation machine, the control system analyzes the ratio of the change value of the pressure to the change value of the the temperature of the hydrogen cylinder in the vehicle and compares the ratio with the rated value in thecontrol system, then the hydrogenation rate can be timely controlled, the ratio of the change value of the pressure intensity to the change value of the the temperature is always within a set range,the filling rate of the hydrogen is not too large, so that the temperature in the hydrogen cylinder is always within a specified range, the filling rate of the hydrogen can be controlled only by comparing the ratio of the change value of the pressure to the change value of the the temperature of the hydrogen cylinder, the principle is simple, and the implementation cost is low.

Description

technical field [0001] The invention relates to a hydrogenation rate control method and a hydrogenation machine. Background technique [0002] A fuel cell is a device that directly converts the chemical energy of fuel into electrical energy. It only needs to input fuel and oxidant to directly output electrical energy through a chemical reaction. As a fuel, hydrogen has the characteristics of high energy efficiency, wide source, renewable, and pollution-free. It has broad application prospects in the field of fuel cells. [0003] Hydrogen is currently used as fuel for fuel cell vehicles and is currently stored in hydrogen bottles. It needs to be filled with hydrogen through a special hydrogenation machine in the hydrogenation station, using the high-pressure hydrogen in the hydrogen storage tank of the hydrogenation machine and the low-pressure hydrogen in the hydrogen bottle of the vehicle. The pressure difference of the hydrogen gas is used to inject the hydrogen gas into ...
