[0061] Direct filling mode, bottle filling mode, bottle charging mode, and automatic hydrogenation mode;

[0062] The above four operation modes are all regulated by the control cabinet 7, and different operation modes are carried out according to different working conditions.

[0063] When in the direct filling mode, the exhaust valve and the hydrogenation valve are in the open state, and the pressure relief valve and the hydrogen storage valve are in the closed state;

[0064] In the direct filling mode, the hydrogen output by the compressor 4 can directly flow to the hydrogenation gun 6, and the object to be hydrogenated outside can be directly filled through the hydrogenation gun 6.

[0065] When in the bottle filling mode, the pressure relief valve and the exhaust valve are in the closed state, and the hydrogen storage valve and the hydrogenation valve are in the open state;

[0066] In the bottle filling mode, when carrying out the hydrogenation operation, the stored hydrogen gas in the hydrogen storage cylinder 5 flows to the hydrogenation gun 6 to carry out the bottle filling operation.

[0072] The skid-mounted base is bolted with a bracket for hanging the hydrogenation gun 6;

[0073] When the hydrogenation gun 6 is not in use, it can be hung on the bracket.

[0074] Working principle:

[0075] In this solution, the exhaust valve, hydrogen storage valve, hydrogen addition valve, and pressure relief valve are respectively represented by Y1, Y2, Y3, and Y4 in the attached drawings;

[0076] In the direct filling mode: The system in the control cabinet 7 first controls to open the exhaust valve and hydrogen addition valve, close the pressure relief valve and hydrogen storage valve, and then sequentially starts the chiller and hydrogen generator 2. When the hydrogen generator 2 operates normally and the pressure in the buffer tank 3 reaches the set value, the compressor 4 automatically starts, and directly inputs hydrogen into the hydrogen filling gun 6 for direct filling. After the filling is completed, the compressor 4, hydrogen generator 2, exhaust valve, hydrogen addition valve, and chiller are sequentially closed, and then the pressure relief valve is opened to release the pressure in the hydrogen filling pipeline to a slightly positive pressure, that is, the operation of the direct filling mode is completed; The chiller is a commonly used cooling device in the prior art, mainly used to cool the hydrogen generator 2 and the compressor 4, and the chiller is also fixed on the skid-mounted base by bolts.

[0077] In the bottle filling mode: The system in the control cabinet 7 sequentially controls to close the pressure relief valve and exhaust valve, open the hydrogen storage valve and hydrogen addition valve, and the system directly enters the hydrogen addition mode for the hydrogen storage bottle 5.

[0078] In the bottle charging mode: The system in the control cabinet 7 sequentially controls to close the pressure relief valve and hydrogen addition valve, open the exhaust valve and hydrogen storage valve, and then sequentially starts the chiller and hydrogen generator 2. When the hydrogen generator 2 operates normally and the pressure in the buffer tank 3 reaches the set value, the compressor 4 automatically starts for the compressor 4 to charge the bottle. After the bottle charging is completed, the compressor 4, hydrogen generator 2, exhaust valve, hydrogen storage valve, and chiller are sequentially closed, and then the pressure relief valve is opened to release the pressure in the hydrogen filling pipeline to a slightly positive pressure, that is, the operation of the bottle charging mode is completed.

[0079] In the automatic hydrogen addition mode: The automatic hydrogen addition mode is an automatic judgment mode of the bottle filling mode and the direct filling mode. After selecting the one-key automatic hydrogen addition mode, the system in the control cabinet 7 sequentially controls to close the pressure relief valve and exhaust valve, open the hydrogen storage valve and hydrogen addition valve, and the system directly enters the hydrogen addition mode for the hydrogen storage bottle 5. When the system judges that the pressure difference between the pressure in the hydrogen storage bottle 5 and the pressure in the hydrogen filling pipeline is less than the set value, it means that the pressure in the hydrogen storage bottle 5 is not enough to continue hydrogen addition. The system automatically switches to the direct filling mode, closes the hydrogen storage valve, opens the exhaust valve, and then sequentially starts the chiller and hydrogen generator 2. When the hydrogen generator 2 operates normally and the pressure in the buffer tank 3 reaches the set value, the compressor 4 automatically starts for the compressor 4 to directly fill. After the filling is completed, the compressor 4, hydrogen generator, exhaust valve, hydrogen addition valve, and chiller are sequentially closed, and then the pressure relief valve is opened to release the hydrogen filling pipeline to a slightly positive pressure, that is, the one-key automatic hydrogen addition operation is completed.

[0080] In this solution, in the attached Figure 1Taking the direction in [description] as an example, the electric control area is on the left side, the hydrogen production area is in the upper middle side, the hydrogen storage area is in the lower middle side, the compression area is on the right side, and the buffer tank 3 is placed between the hydrogen production area and the hydrogen storage area. The whole skid-mounted equipment has a compact structure, thus improving the overall flexibility of the integrated equipment.
