Abstract
The gas adding sub station with the gas adding method in high pressure and the device is made by the gas supplying system of three lines sequence in gas adding station, the high pressure gas supping system connected with the multi lines gas in auto sequencing gas adder. In keeping the normal gas adding pressure, the additional high pressure gas supplying system is opened; the gas adder adds the gas to out according to the low, middle, high pressure and additional high pressure sequence, so the gas supplying time of the low pressure gas bottle is prolonged. The invention has the high gas getting effect and gas transforming effect; it also can save the energy, has low cost, stable gas adding pressure to increase the set distance between the gas adding sub station and mother station, to enlarge the radiating field to benefit for using the gas automotive.
Description
Technical field
The present invention relates to the aerating method and the device of compressed natural gas air entraining substation, particularly a kind of additional high-pressure gas entrainment method and device.
Background technique
The aerating method and the device of domestic and international existing compressed natural gas air entraining substation are the three-way order air supply systems that is connected with three-way air intake type filling machine with three groups of gas cylinder groups of basic, normal, high pressure and corresponding gas supply line at present.Order by basic, normal, high pressure is got the method for gas to the gas combustion automobile aerating from the gas cylinder group, use be the three-wire type filling machine, be referred to as three-way order gas entrainment method usually.In the reality, during owing to the gas combustion automobile aerating, more or less for remaining rock gas in the vehicle-mounted gas cylinder, and residual air pressure difference is not all to be to be about to exhaust.Particularly use the air entraining substation of skid gas cylinder group air feed to adopt three-way order gas entrainment method, run into when the vehicle aerating that residual gas is more, residual air pressure is higher is arranged, the pressure of middle and high air bottle group descends very fast, often forming the low pressure gas cylinder group still has 8-10MPa pressure, and the pressure of gas cylinder group can not remain on the normal aerating scope of the 16-20MPa of national automobile fuel filler gas station design and construction standard (GB50156-2002) regulation.Normally add atmospheric pressure for what keep air entraining substation, have to replace with new gas cylinder group, thereby cause the gas taking rate of gas cylinder group not high, the energy consumption waste is big, and operating cost strengthens, and the aerating pressure surge is big, poor stability.
Summary of the invention
The objective of the invention is to overcome the above-mentioned deficiency of prior art, a kind of gas filling substation additional high-pressure gas-filling method and device are provided.The object of the present invention is achieved like this: gas filling substation additional high-pressure gas-filling method and device are set up the additional high-pressure air supply system by the three-way order air supply system of air entraining substation, connecting multi-thread air intake type sorts filling machine automatically and forms, when keeping normally adding the atmospheric pressure aerating, open by needs the additional high-pressure air supply system, the multi-thread air intake type filling machine that sorts is automatically got gas to additional gas according to the order of basic, normal, high pressure, additional high-pressure, fully prolongs the service life of low pressure gas cylinder group.The additional high-pressure air supply system can be an air supply unit, i.e. one group of additional high-pressure gas cylinder group and corresponding gas supply line; Also can be two above air supply units, i.e. two above additional high-pressure gas cylinder groups and corresponding gas supply line; Additional high-pressure gas cylinder group is identical with used other gas cylinder groups, be the skid form, filling pressure is 20-25MPa, multi-thread air intake type sort automatically filling machine admission line more than three, with increase the additional high-pressure air supply system after be consistent, every pipeline is separately installed with pressure transmitter, can get gas according to the order of basic, normal, high pressure, additional high-pressure automatically.
When the air entraining substation that uses skid gas cylinder group air feed adopts aerating of the present invention, each gas cylinder group of air entraining substation is all answered sufficient 20-25MPa compressed natural gas during beginning, owing to have not too big air pressure difference relatively, formed basic, normal, high air bottle group objectively.The multi-thread air intake type filling machine that sorts is automatically at first got gas by basic, normal, high pressure order from basic, normal, high air bottle group during to additional gas.The pressure difference of basic, normal, high air bottle group can increase gradually, and the pressure of each gas cylinder group is also reducing gradually.When the pressure of gas cylinder group is reduced to can not keep normally adding atmospheric pressure the time, the filling machine that sorts is automatically opened the additional high-pressure air supply system, gets gas by the order of basic, normal, high pressure, additional high-pressure, and the maximum pressure to additional gas rises to 20MPa again like this.At this moment still can continue to utilize the externally normal aerating of low pressure gas cylinder group air feed, fully prolong the service life of low pressure gas cylinder group, when low pressure gas cylinder group hypotony, be changed again.The present invention improves more than 20% for gas cylinder group gas taking rate than prior art, can make the pressure of low pressure gas cylinder group use 2-4MPa, even lower.On same admission line, after former low pressure gas cylinder group is replaced with the gas cylinder group that newly fills, need not again the connecting line of other gas cylinder groups to be done change, the air bottle group just becomes the low pressure gas cylinder group in working online in former, former gas cylinder group just becomes the middle air bottle group in working online, former additional high-pressure gas cylinder group just becomes the gas cylinder group in working online, the gas cylinder group that newly fills that replaces with then is the additional high-pressure gas cylinder group in working online, and the multi-thread air intake type filling machine that sorts is automatically still got gas to additional gas by the order of basic, normal, high pressure, additional high-pressure.So continue operation.
The present invention compared with prior art, the good stability that the gas taking rate height of gas cylinder group, energy saving, fortune efficient height, operating cost be low, add atmospheric pressure.Can increase the distance that is provided with at air entraining substation and female station, enlarge the aerating radiation areas, more help the promotion and application of gas combustion automobile.
