Problems solved by technology
[0004] From the above, it is an economic loss for LNG cylinder users to discharge natural gas into the air through the main safety valve and the vent stop valve and discharge it back into the gas filling station when filling liquid; especially to discharge into the air, not only It is an economic loss, and also has a great impact on environmental protection, because the main component of natural gas is methane, and the impact of methane on the greenhouse effect is dozens of times that of carbon dioxide, and it also has hidden dangers such as fire and explosion, such as Chinese patent CN201120522081. 3. Once the pressurized outlet pipeline is broken, a large amount of liquid will be vaporized after being sprayed out, and fire and explosion will occur when encountering an open flame, so there is a great safety hazard

Embodiment Construction
[0024] A device for collecting and reusing gas released from LNG gas cylinders for vehicles, such as figure 1 As shown, it includes an LNG gas cylinder 1, a main safety valve 2, a vent stop valve 3, a first one-way valve 4, a special adsorbent 5, an adsorption gas storage device 6, and a second one-way valve 7. Wherein the main safety valve 2, the venting stop valve 3 are connected with the gas phase space of the LNG cylinder 1 through pipelines. The main safety valve 2 and the vent stop valve 3 are connected in parallel with the first one-way valve 4, the adsorption gas storage device 6 and the second one-way valve 7 through the pipeline, and the second one-way valve is connected with the gas supply pipeline system 13 connected. The adsorption gas storage device 6 is filled with a special adsorbent 5, i.e. nano-activated carbon, which is a porous carbon-containing substance with a highly developed pore structure. The porous structure of nano-activated carbon provides it with...

The invention discloses a device for collecting and reusing gas released from LNG cylinders for vehicles. The collection and reuse device includes LNG gas cylinders for vehicles; the gas outlet of the LNG gas cylinders for vehicles communicates with the air inlet of the gas supply pipeline system through a pipeline equipped with an economical throttle valve and a liquid outlet stop valve; The throttle valve communicates with the liquid outlet of the vehicle LNG cylinder through a pipeline equipped with an internal check valve; The pipeline of the gas device and the second one-way valve communicates with the air inlet of the gas supply pipeline system. Thus, the present invention absorbs and stores higher-pressure gas, and releases the adsorbed and stored gas for use when the automobile engine system needs to use natural gas.
Description
technical field [0001] The invention relates to a device for collecting and reusing gas released from LNG gas cylinders for vehicles, and belongs to the field of collecting and reusing gas discharged from LNG gas cylinders. Background technique [0002] LNG cylinders are liquefied natural gas storage and transportation equipment. During storage, transportation and use, gaseous natural gas will be generated in the cylinders to increase the pressure in the cylinders. To ensure the safety of LNG cylinders, a main safety device is installed on the extension pipeline of the cylinder Valve; in order to facilitate the filling of LNG cylinders and the maintenance and inspection of LNG cylinders, a vent stop valve is provided on the extension pipeline of the gas cylinders. [0003] During transportation and use, the gas pressure in the cylinder rises to the set pressure of the opening of the main safety valve, and the higher-pressure gas in the cylinder is discharged into the air thr...
