Problems solved by technology

[0005] 2) Since the volume of the steel container cannot be changed, the air pressure in the steel cylinder drops after the transport vehicle supplies air to the air-receiving vehicle
The high cost has kept the price of compressed natural gas high for a long time, restricting the popularization and application of this clean energy

Embodiment Construction

[0029] The present invention will be described in further detail below in conjunction with accompanying drawing:

[0030] The present invention makes use of the existing standard containers and general valves, by grouping the pressure container steel cylinders of the transport vehicle 1, and supplying air to the receiving vehicle in turn, so that the transport vehicle 1 has the functions of transportation and multi-line gas supply at the same time, and can directly supply air to the third line or Five-line gas vending machine 3 gas supply. Realize the gas sales process without power consumption under the condition of maintaining a high gas extraction rate.

[0031] see figure 1 The schematic diagram of the refueling system of the unpowered natural gas substation is shown:

[0032] The gas filling system of the natural gas sub-station of the present invention includes a transport vehicle 1, a gas unloading column 2 and a gas vending machine 3, and the transport vehicle 1 is p...

Abstract

The invention discloses a non-powered natural gas filling system and a filling method thereof. The system comprises a transport vehicle (1), a gas unloading column (2) and a gas vending machine (3). The transport vehicle (1) is provided with A plurality of independent gas supply container groups, each group of containers are respectively connected to an outlet through pipelines and valves and directly connected to the gas vending machine (3) through the corresponding pressure pipeline through the unloading column (2); the gas filling method of the present invention Including the following two methods: 1. Use a single vehicle with a pressure level of 25MPa, each group of 2-4 containers, a total of five groups of containers, to continuously supply air to the receiving vehicle in sequence: 2. Use a pressure level of 25MPa, each vehicle is equipped with There are three groups of transport vehicles with 2-5 containers in each group, and the gas is supplied to the receiving vehicle in the manner of successively replacing the container groups with two vehicles; compared with the prior art, the present invention does not rely on compressors, high and medium pressure storage for stations The gas cylinder group supplements the pressure or the booster oil pump maintains the pressure, and uses the specially designed long-tube transport vehicle for grouping and sequentially supplying gas and the unique way of unloading gas in stages to realize rapid gas sales without power.

Description

technical field [0001] The invention relates to compressed natural gas substation equipment and a gas filling method, in particular to a non-powered natural gas substation gas filling system and a gas filling method. Background technique [0002] At present, there are two types of natural gas vehicle refueling stations commonly used at home and abroad: 1) the gas refueling stations that use natural gas from the pipeline transportation system (pipe network) and sell it on the spot after compression are called standard stations; 2) use the natural gas from pipelines Natural gas is compressed by multiple large-scale equipment and transported in high-pressure containers to distributed gas station groups in different places, which is called the mother-substation system. The centralized compression station is called the parent station, and the gas filling station with the on-board pressure vessel as the gas source is the sub-station. [0003] Existing ordinary substation technolo...
