Detailed Description
For a better understanding of the present invention, the present invention will be further explained below with reference to the drawings and examples.
Example 1
As shown in fig. 1, a hydrogen supply system for a double hydrogenation port passenger car comprises a first hydrogen cylinder 11, a first hydrogenation port 21 correspondingly connected with the first hydrogen cylinder, a second hydrogen cylinder 12, a second hydrogenation port 22 correspondingly connected with the second hydrogen cylinder, an electromagnetic valve 4 connected with the second hydrogen cylinder through a pipeline, and a fuel cell 8 connected with the pipeline between the second hydrogen cylinder 12 and the electromagnetic valve 4 through a tee joint.
The first hydrogenation port 21 and the second hydrogenation port 22 are preceded by a first check valve 31 and a second check valve 32, respectively.
The pipeline between the tee joint and the fuel cell 8 comprises a filter 5, a pressure reducing valve 6 and a manual emptying valve 7 in sequence.
The hydrogenation mode of the single hydrogenation gun is as follows: when the automobile is hydrogenated, the automobile is powered off, the electromagnetic valve 4 is closed, one hydrogenation port is only connected with one hydrogen cylinder in a butt joint mode, one hydrogen cylinder needs to be added, and the other hydrogen cylinder needs to be added, so that the filling volume is reduced, the temperature rise is reduced, the precooling temperature of the hydrogen can be increased, energy is saved, and the condition that hydrogenation is stopped due to too fast temperature rise is avoided; meanwhile, the total volume of the gas cylinder is unchanged, so that the hydrogenation time is not increased.
When the system is used for supplying hydrogen, as shown in fig. 3, the vehicle is electrified, the electromagnetic valve 4 is opened to connect the two hydrogen cylinders, and the system can supply gas to the use end at the same time, as a conventional hydrogen system.
Example 2
As shown in fig. 2, the present invention is different from example 1 in that a double hydrogenation gun hydrogenation mode is adopted: when the automobile is hydrogenated, the automobile is powered off, the electromagnetic valve is closed, at the moment, the two hydrogen cylinders are mutually independent, two hydrogenation guns can be connected simultaneously to carry out hydrogenation, the advantage of hydrogenation by a single hydrogenation gun also exists, and the hydrogenation time is shortened to 50% of the original hydrogenation time.
The above embodiments are only exemplary embodiments of the present invention and are not intended to limit the present invention, the scope of which is defined by the claims. Various modifications and equivalent substitutions of the invention will occur to those skilled in the art, which are within the spirit and scope of the invention.
