Abstract
The invention discloses a vehicle CNG filling substation system. A CNG supply vehicle gets gas from a natural gas main station or common filling station and stores gas by using small CNG cylinder groups which are detachably fixed on the gas supply vehicle, when the gas supply vehicle arrives at a filling substation, is stored in the filling substation after the CNG cylinder groups are unloaded by using a loading and unloading forklift, a plurality of CNG cylinder groups can form a gas cylinder warehouse, any one CNG cylinder group in the gas cylinder warehouse can be directly connected with a gas inlet of a compressor system through a quick disconnect coupling to introduce CNG into the compressor system; and the compressor system is an adaptive variable working condition compressor system, the inlet pressure of the compressor system is 2-15MPa and the output pressure is 25MPa, and the natural gas in the gas cylinder groups is pumped to 2MPA, thereby enabling the gas pumping rate to reach 92 percent. Pressurized natural gas enters a sequence control plate, high, medium and low gas storage tanks and CNG dispensers are respectively introduced, wherein the CNG dispensers supply the gas for CNG vehicles.
Description
Technical field
The present invention relates to a kind of vehicle CNG filling station, particularly a kind of vehicle CNG filling substation system.
Background technology
CNG (compression natural gas) is promoted rapidly in China as a kind of clean energy resource, particularly compare with gasoline irreplaceable advantage is being arranged aspect economy and the environmental protection as automobile fuel, but, owing to be subjected to the restriction of technology and fund, the development of vehicle CNG is slower at present, its reason shows as: general common CNG gas station builds the place that covers at gas distributing system, and by the direct air feed of gas distributing system, building so common gas station distributed by natural air-air source and the influence of gas distributing system, there be not the place of laying can only build the CNG air entraining substation away from natural air-air source and gas distributing system, but the technology of existing C NG air entraining substation falls behind, operating efficiency is low, particularly fall behind from the CNG technology that car unloads gas to the CNG substation of supplying gas, can not unload gas fully, make the CNG car residual air after unloading gas of supplying gas more, cause the transport power waste, improved traffic cost, simultaneously, the CNG compression system that existing air entraining substation adopts is generally single-stage or multistage compression substation system, need CNG supplied gas and introduce compression system pressurization output again behind the CNG expenditure and pressure of car, cause great energy dissipation.
Summary of the invention
The purpose of this invention is to provide a kind of vehicle CNG filling substation system, this system is owing to adopt the adaptive variable working condition compressor assembly, and the CNG that makes CNG send automobile to be transported to air entraining substation need not through unloading the gas process, directly introduces compressor assembly pressurization output.
Technical scheme of the present invention is:
A kind of vehicle CNG filling substation system, by CNG supply gas car from the natural gas carrier station or common gas station get gas, be transported to the CNG air entraining substation and deposit, CNG is introduced the substation compressor assembly, natural gas via sequence control dish after the pressurization enters storage tank and filling machine, and filling machine is to refueling.
Described CNG supplies gas car by the gas storage of Small-sized C NG gas cylinder group, and CNG supplies gas and by fork truck CNG gas cylinder group unloaded after car arrives the CNG air entraining substation, deposits a plurality of gas cylinder groups in the substation and forms gas bottle depot.
Described substation compressor assembly is the adaptive variable working condition compressor assembly, this compressor assembly can send the gas cylinder group of automobile directly to introduce natural fuels by CNG, need not through the expenditure and pressure process, the inlet pressure scope of described adaptive variable working condition compressor assembly is 2-25Mpa, and delivery pressure is 25Mpa.And the natural fuels in the CNG gas cylinder group can be evacuated to 2Mpa, make gas taking rate reach 92%.Natural gas via sequence control dish after the pressurization enters storage tank and filling machine.
Beneficial effect of the present invention:
Car adopts removably small-sized gas cylinder group because CNG supplies gas, and it can be unloaded the gas cylinder group that is full of CNG in air entraining substation form gas bottle depot, has improved conveying efficiency, has guaranteed the gas-storing capacity that air entraining substation is enough.
Owing to adopt the adaptive variable working condition compressor assembly, make the CNG that is transported to the CNG air entraining substation need not directly to introduce compressor assembly through expenditure and pressure, simplify whole C NG air entraining substation operational system, improved operating efficiency, and reduced the construction cost of air entraining substation.
Description of drawings
Accompanying drawing is a vehicle CNG filling substation system process flow diagram of the present invention
The specific embodiment
Referring to accompanying drawing, vehicle CNG filling substation system of the present invention, by CNG supply gas car from the natural gas carrier station or common gas station get gas, CNG supplies gas car by the gas storage of Small-sized C NG gas cylinder group, CNG gas cylinder group is fixed on the car of supplying gas in mode removably, after the car of supplying gas arrives the CNG air entraining substation, CNG gas cylinder group is unloaded leave in the substation by the loading and unloading fork truck, a plurality of CNG gas cylinder groups can form gas bottle depot, arbitrary gas cylinder group in the gas bottle depot all can be by the admission port direct connection of quick coupling and compressor assembly, CNG is introduced compressor assembly, compressor assembly is the adaptive variable working condition compressor assembly, the inlet pressure scope of this compressor assembly is 2-25Mpa, and delivery pressure is 25Mpa, the natural fuels in the gas cylinder group can be evacuated to 2Mpa, thereby make gas taking rate reach 92%, enter the sequence control dish by the back natural fuels that pressurizes, introduce senior middle school's low pressure gasholder and filling machine more respectively, filling machine is the CNG refueling.
