Problems solved by technology
[0003] Disadvantages of the prior art: energy waste, which does not meet the needs of a conservation-oriented society; economic loss, although the amount of emission each time is not large, it is still a considerable economic loss over time; Although it is simple, it has certain dangers. It will cause the concentration of natural gas in the air column to rise in a short period of time, which may threaten the safety of the station and operators; environmental pollution, the natural gas will carry some oil and other impurities, and the oil will be polluted after venting. It will be attached to the bottom of the aeration hood. For a long time, the aeration hood is covered with oil, polluting the environment and lacking in beauty

The invention discloses a compressed natural gas primary station gas filling column vent natural gas recovery device and method. The device comprises a plurality of gas filling columns. The gas filling columns are connected with a pipe I and a pipe II through a pipeline. The pipe I is connected with a buffer tank I. The pipe II is connected with a centralized bleeder pipe. A check valve I and ballvalves II are arranged on the pipe I. Ball valves II are arranged on the pipe II. A pipe III is connected to the buffer tank I and communicates with the pipe II. A safety valve is arranged on the pipe III. A pipe IV and a pipe V are connected to the buffer tank I. The pipe V is connected with a compressor. An inlet of the compressor is connected with a buffer tank II. A check valve II is arrangedon the pipe IV. A downstream gas use point is connected to the pipe V. The bottom of the buffer tank I is provided with a blow-down valve. By adopting the compressed natural gas primary station gas filling column vent natural gas recovery device, energy is saved, economic losses are reduced, the safety of a primary gas filling station is improved, and environmental pollution is avoided.
Description
technical field [0001] The invention relates to the field of compressed natural gas venting devices, in particular to a device and method for venting natural gas from an air filling column in a compressed natural gas parent station. Background technique [0002] The form of venting natural gas at the refueling mother station: adopt the form of centralized and centralized release pipes, and collect the emptied natural gas in the mother station to the centralized and centralized release pipe for release; release on the spot. [0003] Disadvantages of the prior art: energy waste, which does not meet the needs of a conservation-oriented society; economic loss, although the amount of emission each time is not large, it is still a considerable economic loss over time; Although it is simple, it has certain dangers. It will cause the concentration of natural gas in the air column to rise in a short period of time, which may threaten the safety of the station and operators; environme...
