Hydraulic CNG (Compressed Natural Gas) gas filling substation and pipeline system, control system and control method thereof

Abstract

The invention discloses a pipeline system and a control system of a gas filling substation and the gas filling substation comprising the same and also discloses a control method of the gas filling substation. The disclosed pipeline system of the gas filling substation comprises a pressurization mechanism and a gas dispenser and also comprises a first gasbomb set and a second gasbomb set, wherein the first gasbomb set comprises a plurality of first gasbombs, and the second gasbomb set comprises a pluraity of second gasbombs; the output ends of the first gasbombs are communicated with the first input port of a distributing valve by a first output control valve; the output ends of the second gasbombs are communicated with the second input port of the distributing valve by a second output control valve; and the pressurization ends of the first gasbombs and the pressurization ends of the second gasbombs are respectively communicated with the pressurization port the pressurization mechanism by a first pressurization control valve and a second pressurization control valve. The technical scheme can improve the gap pickup rate of the system while improving the gas supply capacity of the hydraulic CNG (Compressed Natural Gas) gas filling substation.

Description

technical field [0001] The present invention relates to a hydraulic CNG (Compressed Natural Gas, compressed natural gas) gas filling technology, in particular to a pipeline system, a control system of a hydraulic CNG gas filling substation and a hydraulic system including the pipeline system and the control system. A control method for a type CNG sub-station and a hydraulic CNG sub-station. Background technique [0002] At present, natural gas has been widely used in many aspects of society and life. Among them, the use of natural gas as fuel to drive the operation of other equipment has become an important aspect of natural gas utilization. In order to facilitate transportation and loading, compressed natural gas (CNG) is formed by pressurizing natural gas, which has become one of the important ways of natural gas utilization. [0003] In order to expand the scope of use of CNG, currently it is usually adopted to set up a CNG refueling sub-station at a predetermined posit...

AI Technical Summary

Problems solved by technology

Although the hydraulic CNG substation can improve the gas supply capacity, because its self-pressurized steel cylinder relies on internal pressure to supply gas to the outside, the stagnant pressure inside the cylinder is high, resulting in a decrease in the gas intake rate of the entire system
